Answer 1

Answer:

5.97 cm  to 3 significant figures.

Step-by-step explanation:

The diameter of the circle will be equal to the length of the diagonal of the square.

Area = 56 = πr^2

r^2 = 56 / π

r = √(56 / π) =  4.222 cm

So the diameter = 8.444 cm.

This  is  = diagonal of the square so, by The Pythagoras Theorem:

x^2 + x^2 = 8.444^2     where x  is the side of the square.

x^2 = (8.444)^2 / 2

x^2 = 35.651

x =  5.971 cm

Answer 2
that would be a=5.97cm

How to find the legs of a right triangle with only the hypotenuse?

Answers

Let x = legs of right triangle.

The set up would be:

x^2 + x^2 = (hypotenuse)^2

Understand?

To find the legs of a right triangle with only the hypotenuse known, the Pythagorean theorem is used. Without extra information like an angle or one leg length, it's impossible to find the specific leg lengths due to the infinite possibilities of right triangle configurations with the same hypotenuse length.

The question involves finding the lengths of the legs of a right triangle when only the length of the hypotenuse is known. Utilizing the Pythagorean theorem, which states that in a right triangle the square of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b), expressed as a² + b² = c². To find the lengths of the legs (a and b) given the hypotenuse (c), one needs additional information such as the angle of the triangle or the length of one of the legs.

Without such information, it is not possible to determine the specific lengths of the legs because there are infinitely many right triangles with different sets of leg lengths that could have the same hypotenuse length. Therefore, to address this problem, one might use trigonometry if any angle is known, or apply other relevant context or given data.

Step-by-step explanation:

500 x .05 =25+500= 525 which is the second concert. Multiply that by .05 which is 26.25, add that to 525 to get 551.25 which is not 650.

Five friends are going to the theater. They have purchased a row of five seats with an aisle on either end. James doesn't want to sit next to Jill Betty and Herb are dating and want to sit next to each other Bob must sit on an aisle Provide a seating order that conforms to the above rules. An example of an invalid seating order is: James, Betty, Herb, Bob, Jill The above arrangement is invalid because: Bob is not sitting on an aisle. Specify the seating order as the names separated by s (as in the above example). Please be sure to spell the names correctly, including capitalization.

Answers

Answer:

Bob, Jill, Betty, Herb, James

Final answer:

A valid seating arrangement for the five friends is either Bob, Betty, Herb, James, Jill, or Jill, James, Herb, Betty, Bob. Each arrangement adheres to all given conditions: Bob is on an aisle, Betty and Herb are seated together, and James is not sitting next to Jill.

Explanation:

To solve the seating problem for the five friends going to the theater, we must adhere to the conditions: Bob must sit on an aisle, James cannot sit next to Jill, and Betty and Herb want to sit next to each other. Bearing in mind that there's an aisle on either side of the row of five seats, we can begin by placing Bob on an aisle seat since he must sit on one. This can either be the first seat on the left or the right. Since James doesn't want to sit next to Jill, we can't place Jill next to Bob if we sit James on the other end to maximize distance between them. Betty and Herb must sit together, which can only happen in the three seats left in the middle.

Here is a seating arrangement that satisfies all conditions: Bob, Betty, Herb, James, Jill. In this arrangement, Bob is on an aisle, Betty and Herb are seated together, and James is not sitting next to Jill.

Alternatively, if we place Bob on the other aisle, we get: Jill, James, Herb, Betty, Bob. Again, all conditions are met. Bob is on an aisle, Betty and Herb are sitting together, and James is not sitting next to Jill.

Your drawer contains 6 red socks and 10 blue socks. It's too dark to see which are which, but you grab two anyway. What is the probability that both socks are red?

Please help ASAP. I have a test tomorrow

Answers

Answer:

1/8

Step-by-step explanation:

There's two ways you can solve this.

Method 1: Let's say you grab the socks one at a time.  The first sock you grab has a 6/16 probability of being red.  If the sock is red, then the second sock you grab has a 5/15 probability of being red, because there's one less red sock and one less sock total.  So the overall probability is:

P = 6/16 × 5/15 = 1/8

Method 2: There are ₆C₂ ways to choose 2 red socks from 6 red socks.  There are ₁₆C₂ ways to choose any 2 socks from all 16 socks.  So the probability that both socks you choose are red is:

P = ₆C₂ / ₁₆C₂ = 15 / 120 = 1/8

The probability that both socks are red is 1/8 if the drawer contains 6 red socks and 10 blue socks

What is probability?

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

We have:

Total number of socks= 6+10 = 16

Total ways of selecting = C(16, 2) = 120

Ways of selecting 2 red socks from 6 = C(6, 2) = 15

The probability = 15/120 = 1/8

Thus, the probability that both socks are red is 1/8 if the drawer contains 6 red socks and 10 blue socks

N = amount of C-14 at time t
K = 0.0001
t = time, in years

Answers

Answer:

11,394  years old

Step-by-step explanation:

The equation looks like this:

[tex]N=N_{0}e^{kt}[/tex]

The only thing left up to us is to decide what value should go in for N.  Since we are told that 32% of the original amount is what the hiker finds, we are operating in percentages.  Before any decomposition took place, the amount of skull was 100%.  Filling in now we have:

[tex]100=32e^{.0001t}[/tex]

Divide both sides by 32 to get

[tex]3.125=e^{.0001t}[/tex]

In order to get that t out of the exponential position that it is currently in, we will take the natural log of both sides, since a natural log "undoes" an e (that is because the base of a natural log is e).  Taking the ln of both sides and utilizing that rule for natural logs and e's gives us:

ln(3.125) = .0001t

Divide both sides by .0001 to get that

t = 11,394 years

Jace has consumed 1,500 calories so far today. He has also burned off 400 calories at the gym. He would like to keep his daily calorie total to 1,900 calories per day. How many calories does he have left to consume for the day? Is 1,100 a viable solution to this problem?
===================================
Yes; 1,100 is less than 1,500.
No; 1,100 is more than the 400 he burned off at the gym.
No; 1,100 will cause him to exceed 1,900.
Yes; 1,100 is less than 1,900

Answers

Answer:

No, it will cause him to exceed 1900.

Step-by-step explanation:

1,500 - 400 = 1,100 (his total after the gym)

1,100 + 1,100 exceeds 1,900. He wants to keep his total below 1,900, so this is not a viable solution.

Answer:

No; 1,100 will cause him to exceed 1,900.

Step-by-step explanation:

The rationale for this problem is basic.

Jace established a diet restricted to 1900kcal.

If he started 1500kcal and burned 400kcal in the gym, Jane's partial jump is 1100 calories.

Thus, it can still eat the total of 1900-100 = 800kcal.

Any value over 800kcal will exceed the tax threshold and will disrupt Jane's results.

Step-by-step explanation:

2x = -2x + 11

Add 2x on both sides

4x = 11

Divide 4 on both sides

x = 11/4

x = 2.75

Round to nearest tenth

x is about 2.8

Please mark me for brainliest :D !! Thanks!

Answer:

x = 2.8

Step-by-step explanation:

2x = - 2x + 11                       Add 2x to both sides.

2x+2x = -2x+2x + 11           Combine

4x = 11                                 Divide by 4

4x/4 = 11/4

x = 2 3/4

x = 2.75

Rounded to the 10th place, you would get 2.8

A cricketer has a mean 58 runs in nine innings.Find out how many runs are to be scoredin the 10th inningd to raise the mean scroce to 61.

Answers

Answer:

88

Step-by-step explanation:

Nine innings have a mean of 58 runs, and the tenth inning will have x runs.  So the overall mean is:

μ = (9×58 + x) / 10

We want the mean to be 61, so:

61 = (9×58 + x) / 10

610 = 522 + x

x = 88

The cricketer must score 88 runs to raise the mean to 61.

sherrie is baking a pie for her family. she leaves the room and comes back to 35% of the pie having been eaten before she can put the topping on. how much 1 square inch strips of dough will she need for the top, now that a portion is missing? round your answer to the nearest while nimber.​

Answers

Answer:

131

Step-by-step explanation:

We need to find the area of the top of the pie that is leftover. To do this, we use the formula for the area of a circle and multiply by 0.65 since that is how much of the pie is left.

A = 0.65π[tex]r^{2}[/tex] = 0.65π[tex]8^{2}[/tex] = 130.69025 [tex]in^{2}[/tex]

If each strip of dough is 1 square inch, the total strips of dough needed is 131.

The total strips of dough needed is 131 if Sherrie is baking a pie for her family. she leaves the room and comes back to 35% of the pie.

What is a circle?

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have:

Sherrie is baking a pie for her family. she leaves the room and comes back to 35% of the pie having been eaten before she can put the topping on.

Area of circle:

A = 0.65πr² = 0.65π(8)²

A =  130.69025 square inches ≈ 131 square inches

If each strip of dough is 1 square inch

The total strips of dough needed = 131/1 = 131

Thus, the total strips of dough needed is 131 if Sherrie is baking a pie for her family. she leaves the room and comes back to 35% of the pie.

Triangle QRS has vertices Q(8, –6), R(10, 5), and S(–3, 3). What are the coordinates of the vertices of the image of the triangle after a translation of T–7.6, 4.3(x, y)?

Answers

Answer:

Q'(0.4,-1.7),R'(2.4,9.3), S'(-10.6,7.3)

Step-by-step explanation:

we know that

The rule of the translation is equal to

(x,y) -----> (x-7.6,y+4.3)

That means---> the translation is 7.6 units left and 4.3 units up

Find the coordinates of the vertices of the image

Q(8,-6) -----> Q'(8-7.6,-6+4.3)

Q(8,-6) -----> Q'(0.4,-1.7)

R(10,5) -----> R'(10-7.6,5+4.3)

R(10,5) -----> R'(2.4,9.3)

S(-3,3) -----> S'(-3-7.6,3+4.3)

S(-3,3) -----> S'(-10.6,7.3)

The coordinates of the vertices Q, R, and S of the image of the triangle after a translation are (0.4, -1.7), (2.4, 9.3), and (-10.6, 7.3)

Translation is a way of changing the location of an object on the xy plane.

Given the vertices of the triangle QRS as

Q(8, –6)

R(10, 5)

S(–3, 3)

If the coordinate of the vertices is translated under the rule (x–7.6, y+4.3)

For Q'

Q' = (8-7.6, -6+4.3)

Q' = (0.4, -1.7)

For R':

Q' = (10-7.6, 5+4.3)

Q' = (2.4, 9.3)

For the coordinate S'

S' = (-3-7.6, 3+4.3)

S' = (-10.6, 7.3)

Hence the coordinates of the vertices Q, R, and S of the image of the triangle after a translation are (0.4, -1.7), (2.4, 9.3), and (-10.6, 7.3)

A. AC = 14 cm; CE = 8 cm
B. AC = 12 cm; CE = 7 cm
C. AC = 10 cm; CE = 5 cm
D. AC = 5 cm; CE = 10 cm

Answers

Answer:

C

Step-by-step explanation:

Step 1: find BC

Given Triangles ABC and ADE are similar,

[tex]\frac{AB}{AD}[/tex] = [tex]\frac{BC}{DE}[/tex]

BC = [tex]\frac{AB}{AD}[/tex] x DE

= [tex]\frac{8}{8 + 4}[/tex] x 9

= 6 cm

Step 2: use Pythagorean theorem to find AC and / or AE

Consider triangle ABC,

by Pythagorean theorem,

AB² + BC² = AC²

AC² = 6² + 8² = 100

AC = √100 = 10 (answer... we can see that C is the only one with AC=10.

Step 3: Verify.. even though we know that it is C because AC  = 10,  you can verify that the ansewer is correct by finding CE and confirming that CE=5

By using similar triangles ABC and ADE,

AC/AE = AB / AD

AE = AD/AB x AC = 12/8 x 10 = 15

CE = AE - AC = 15 - 10 = 5 (answer confirmed)

Find an nth degree polynomial function calculator n=4 -1,3,2+4i are zeros

Answers

Step-by-step explanation:

By the fundamental theorem of algebra, the degree of the polynomial equals the number of roots (including complex and multiplicities, i.e. multiple roots).

Since n=4, we expect to find 4 roots, although we are only given three, namely -1,3,2+4i.

Fortunately, if the polynomial has real coefficients (which we will ASSUME), for any complex root to exist, its conjugate is also a root to the equation.

Since the conjugate of 2+4i is 2-4i, we now have all four roots, -1, 3, 2+4i, 2-4i.

An n-degree polynomial may be construct by the product of (x-ri) where ri are the roots.  This means

P(x) = (x-(-1))(x-3)(x-2-4i)(x-2+4i), which is

P(x) = (x+1)(x-3)(x-2-4i)(x-2+4i)

When expanded, P(x) = x^4-6x^3+25x^2-28x-60

Check:

sum of roots = (-1+3+2+4i+2-4i) = 6  (same as negative of coefficient of term x^3)  ok

product of roots = (-1)(3)(2+4i)(2-4i)=-3*20 = -60  = constant term,  ok.

Note: kP(x) is also a polynomial with the same four roots, where k=any real number.  P(x) is a particular case where k=1.

Final answer:

The 4th degree polynomial with given zeros -1, 3, and 2+4i, can be derived from these roots and is of the form f(x) = a(x+1)(x-3)(x-2-4i)(x-2+4i). Complex roots always appear in conjugate pairs if the coefficients of the polynomial are real numbers.

Explanation:

The subject of the question is related to the Mathematics of polynomials. Specifically, the question requests the equation of an nth degree polynomial function with n=4 where the zeros include -1, 3, and 2+4i. Given that we have a 4th degree polynomial and we already have 3 roots, we are missing one more. In mathematics, complex roots always come in pairs, so if 2+4i is one of the roots, then its conjugate 2-4i must also be a root.

So, the four roots are: -1, 3, and 2±4i. The polynomial can then be constructed by setting these roots as factors of the polynomial which would then be of the form:

f(x) = a(x+1)(x-3)(x-2-4i)(x-2+4i)

Where 'a' is a constant that will be 1 if the leading coefficient is not specified in the problem.

Trial and error isn't so difficult for this problem. The final price will be an even number of cents. Without those pennies added, the price per turkey must be below an integer number of cents, but within 1/8 cent of that integer number.

167.90/72 = 2.3319... (too high)267.90/72 = 3.7208... (too high)367.90/72 = 5.1097... good candidate467.90/72 = 6.4986... (too low)567.90/72 = 7.8875 (too low)667.90/72 = 9.2763... (too low)

For higher first digits of the total cost, the per-turkey cost is more than 3 digits.

For our "good candidate", the per-turkey cost will be $5.11, so the total bill will be $5.11×72 = $367.92  . . . .  matches the required digits.

A delivery truck is transporting boxes of two sizes: large and small. The large boxes weigh 50 pounds each, and the small boxes weigh 30 pounds each. There are 120 boxes in all. If the truck is carrying a total of 4900 pounds in boxes, how many of each type of box is it carrying?A delivery truck is transporting boxes of two sizes: large and small.

If the truck is carrying a total of 4900 pounds in boxes, how many of each type of box is it carrying?

Answers

Answer:

55 small boxes, 65 large boxes.

Step-by-step explanation:

First, we let x = the amount of big boxes and let y = the amount small boxes. Then, we know that any combination of such will equal 120 so we say

x + y = 120

We also know that we have to fill 4900 pounds, so we can say

50x + 30y = 4900

Then, we can use either substitution or elimination. I'll do substitution. we make the first equation

x = 120 - y

And now we can plug this into our second equation

50(120 - y) + 30y = 4900

Then we distrubute

6000 - 50y + 30y = 4900

Then simplify

6000 - 20y = 4900

Subtract 6000 from both sides

-20y = -1100

then divide both sides by -20

y = 55

so there are 55 small boxes, which means we can subtract 55 from 120 to get 65 large boxes.

The truck is carrying 65 large boxes and 55 small boxes,

x + y = 120 (total number of boxes)

50x + 30y = 4900 (total weight of the boxes in pounds)

First, we can solve one of the equations for one variable and then substitute that into the other equation. Starting with the first equation:

x = 120 - y

Now substitute x in the second equation:

50(120 - y) + 30y = 4900

6000 - 50y + 30y = 4900

-20y = -1100

y = 55

Now we know there are 55 small boxes, we can go back to the first equation to find x:

x + 55 = 120

x = 120 - 55

x = 65

Therefore, the truck is carrying 65 large boxes and 55 small boxes.

Abby took out a car loan for $10,090 that has a 0% APR for the first 22 months and will be paid off with monthly payments over 5 years. For how many months will Abby be charged interest?


A. 82 months

B. 60 months

C. 22 months

D. 38 months

Answers

Answer:

d 38 months

Step-by-step explanation:

Answer:

The correct answer is D. 38 months

Step-by-step explanation:

Abby took out a car loan with monthly payments over 5 years. Each year has 12 months. So the total number of payments will be 5 (years) multiplied by 12 (months).

x=5*12=60 months

The first 22 months are without interest, so the months that have interest are the rest of then.

x'= 60-22= 38 months
