Jared has some quarters and dimes that total $5.50. If he has 8 more quarters that dimes, how much dimes does Jared have?

Answer:

Here's what I get.

Step-by-step explanation:

Question 10

The general equation for a sine function is

y = a sin[b(x - h)] + k

Here's what the parameters control:

a = amplitude

k = vertical shift

b = the period (period = 2π/b; If period = 2π/3, b = 3)

h = horizontal shift

Reflect across y-axis (x ⟶ -x)

Your sine function will be:

[tex]\begin{array}{rllll}y = & a \text{ sin}[ & b(x- & h)] + & k)\\& \downarrow & \downarrow & \downarrow & \downarrow\\& 4 & 3 & \frac{\pi}{4} & 3\\\end{array}[/tex]

Here are the effects of each parameter.

(a) Amp = 4

Increases the amplitude by a factor of 4 (Fig. 1)

(b) Up 3

k = 3. The graph shifts up three units (Fig. 2).

(c) Period = 2π/3

Set k = 3. The period changes from 2π to 2π/3 (Fig. 3).

Notice that you now hav3 three waves between 0 and 2π, where originally you had one.

(d) Right π/4.

Set h = 4. The graph shifts right by π/4.

notice how the trough at ½π shifts to ¾π.

(e) Reflect about y-axis

Set x equal to -x. Notice how the trough at (¾π, -1) is transformed to the trough at (-¾π, -1) (Fig. 5).

Question 12

y = a cos[b(x - h)] + k

a = 2

Per = 10π/3 ⟶ b = 3/5

h = 0

k = 0

Reflect over x-axis: y ⟶ -y

(a) a = 2

The amplitude is doubled.

(b) Per = 10π/3 ⟶ b = 3/5

The period (peak-to-peak distance) lengthens to 10π/3.

(c) Reflect about x-axis (y ⟶ -y)

All peaks are transformed into troughs and vice-versa.

Answer:

y = 4

let's recall that a cube is just a rectangular prism with all equal sides, check picture below.

[tex]\bf \textit{volume of a cube}\\\\ V=s^3~~ \begin{cases} s=&length~of\\ &a~side\\ \cline{1-2} V=&27000 \end{cases}\implies 27000=s^3\implies \sqrt[3]{27000}=s\implies 30=s \\\\[-0.35em] ~\dotfill\\\\ \textit{surface area of a cube}\\\\ SA=6s~~\begin{cases} s=&length~of\\ &a~side\\ \cline{1-2} s=&30 \end{cases}\implies SA=6(30)\implies SA=180[/tex]

Answer:

B. <Q = <R

Step-by-step explanation:

Angles are related to their intercepted arcs. An intercepted arc is found by finding the arc segment on a circle whose endpoints connect with the segments that make up an angle.

In this case, TQ and SQ make up <Q, so TS is the intercepted arc of <Q. However, TR and SR make up angle <R as well, making TS the intercepted arc of <R as well.

This means that because the angles share an intercepted arc, they are congruent.

The answer is does matter.

Answer:

x = 8.3

Step-by-step explanation:

Given a tangent and 2 secants drawn to the circle from an external point then

The square of the measure of the tangent is equal to the product of the measures of the secant's external part and the entire secant.

Using the secant with measure 4 + x, then

4(4 +x) = 7²

16 + 4x = 49 ( subtract 16 from both sides )

4x = 33 ( divide both sides by 4 )

x = 33 ÷ 4 = 8.25 ≈ 8.3 ( nearest tenth )

Answer:

B. 60

Step-by-step explanation:

The opposite sides of a parallelogram are parallel and congruent.

This implies that:

|UV|=|XW|

From the diagram; |UV|=15

and [tex]|XW|=\frac{1}{4}y[/tex]

We equate the two side lengths to get:

[tex]15=\frac{1}{4}y[/tex]

We multiply both sides by 4 to obtain:

[tex]4\times 15=4\times \frac{1}{4}y[/tex]

This implies that:

y=60

Answer:

Step-by-step explanation:

Answer:

Part 4) [tex]sin(\theta)=\frac{12}{13}[/tex]

Part 10) The angle of elevation is [tex]40.36\°[/tex]

Part 11) The angle of depression is [tex]78.61\°[/tex]

Part 12) [tex]arcsin(0.5)=30\°[/tex]  or [tex]arcsin(0.5)=150\°[/tex]

Part 13) [tex]-45\°[/tex]  or [tex]225\°[/tex]

Step-by-step explanation:

Part 4) we have that

[tex]cos(\theta)=-\frac{5}{13}[/tex]

The angle theta lies in Quadrant II

so

The sine of angle theta is positive

Remember that

[tex]sin^{2}(\theta)+ cos^{2}(\theta)=1[/tex]

substitute the given value

[tex]sin^{2}(\theta)+(-\frac{5}{13})^{2}=1[/tex]

[tex]sin^{2}(\theta)+(\frac{25}{169})=1[/tex]

[tex]sin^{2}(\theta)=1-(\frac{25}{169})[/tex]  

[tex]sin^{2}(\theta)=(\frac{144}{169})[/tex]

[tex]sin(\theta)=\frac{12}{13}[/tex]

Part 10)

Let

[tex]\theta[/tex] ----> angle of elevation

we know that

[tex]tan(\theta)=\frac{85}{100}[/tex] ----> opposite side angle theta divided by adjacent side angle theta

[tex]\theta=arctan(\frac{85}{100})=40.36\°[/tex]

Part 11)

Let

[tex]\theta[/tex] ----> angle of depression

we know that

[tex]sin(\theta)=\frac{5,389-2,405}{3,044}[/tex] ----> opposite side angle theta divided by hypotenuse

[tex]sin(\theta)=\frac{2,984}{3,044}[/tex]

[tex]\theta=arcsin(\frac{2,984}{3,044})=78.61\°[/tex]

Part 12) What is the exact value of arcsin(0.5)?

Remember that

[tex]sin(30\°)=0.5[/tex]

therefore

[tex]arcsin(0.5)[/tex] -----> has two solutions

[tex]arcsin(0.5)=30\°[/tex] ----> I Quadrant

or

[tex]arcsin(0.5)=180\°-30\°=150\°[/tex] ----> II Quadrant

Part 13) What is the exact value of [tex]arcsin(-\frac{\sqrt{2}}{2})[/tex]

The sine is negative

so

The angle lies in Quadrant III or Quadrant IV

Remember that

[tex]sin(45\°)=\frac{\sqrt{2}}{2}[/tex]

therefore

[tex]arcsin(-\frac{\sqrt{2}}{2})[/tex] ----> has two solutions

[tex]arcsin(-\frac{\sqrt{2}}{2})=-45\°[/tex] ----> IV Quadrant

or

[tex]arcsin(-\frac{\sqrt{2}}{2})=180\°+45\°=225\°[/tex] ----> III Quadrant

A

Step-by-step explanation:

Find the value of x in each equation then compare the solutions from the least to the greatest

In A

5( x-6)+3x=3/4(2x-8) ------------Open brackets

5x-30+3x=3/2x-6

5x+3x-30=3/2x-6

8x-3/2x=-6+30---------------collect like terms

16x-3x=48

13x=48-----------------dived both sides by 13

x=48/13 = 3.7

In B

2.7(5.1x+4.9)=3.2+28.9-------------open bracket

13.77x+13.23=32.1

13.77x=32.1-13.23---------------collect like terms

13.77x=18.87

x=18.87/13.77----------------------divide both sides by 13.77

x=1.37

In C

5(11x-18)=3(2x+7)--------------------open brackets

55x-90=6x+21

55x-6x=21+90-----------------------collect like terms

49x=111----------------------------------divide both sides by 49 to get x

x=111/49 = 2.27

From the solutions, the least value of x is in B, then C ,and finally A

Equation B:[tex]\(x \approx 1.371\)[/tex]

Equation C:[tex]\(x \approx 2.2653\)[/tex]

Equation A: [tex]\(x = \frac{48}{13}\)[/tex]

Order from least to greatest: B, C, A.

To solve each equation, let's start by simplifying each side of the equation step by step.

Equation A:[tex]\(5(x-6) + 3x = \frac{3}{4}(2x - 8)\)[/tex]

Step 1: Distribute the numbers:

[tex]\(5x - 30 + 3x = \frac{3}{4}(2x) - \frac{3}{4}(8)\)[/tex]

Step 2: Combine like terms:

[tex]\(8x - 30 = \frac{3}{2}x - 6\)[/tex]

Step 3: To get rid of the fraction, multiply both sides by 2:

(16x - 60 = 3x - 12)

Step 4: Move all (x) terms to one side by subtracting (3x) from both sides:

(16x - 3x - 60 = -12)

Step 5: Combine like terms:

(13x - 60 = -12)

Step 6: Add 60 to both sides to isolate (x):

13x = 48

Step 7: Divide both sides by 13 to solve for (x):

[tex]\(x = \frac{48}{13}\)[/tex]

Equation B: 2.7(5.1x + 4.9) = 3.2 + 28.9

Step 1: Distribute the number:

13.77x + 13.23 = 32.1

Step 2: Move the constant to the other side by subtracting 13.23 from both sides:

13.77x = 18.87

Step 3: Divide both sides by 13.77 to solve for (x):

x ≈ 1.371

Equation C: (5(11x - 18) = 3(2x + 7)

Step 1: Distribute the numbers:

55x - 90 = 6x + 21

Step 2: Move all (x) terms to one side by subtracting (6x) from both sides:

55x - 6x - 90 = 21

Step 3: Combine like terms:

49x - 90 = 21

Step 4: Add 90 to both sides to isolate (x):

49x = 111

Step 5: Divide both sides by 49 to solve for (x):

x ≈ 2.2653

Now, let's order these solutions from least to greatest:

[tex]\(x= 1.371\)[/tex] (from Equation B)

[tex]\(x = 2.2653\)[/tex] (from Equation C)

[tex]\(x = \frac{48}{13}\)[/tex] (from Equation A)

So, the order from least to greatest based on their solutions is Equation B, Equation C, and then Equation A.

No, Katie has the advantage.

Katie has 5 distinct letters.

Nathan has 4 distinct letters.

They have one overlap (a).

Katie can expect to win 4 out of 26 games.

Nathan can expect to win 3 out of 26 games.

Since Katie has more distinct letters, she has the advantage, so it is not a fair game.

Answer:

Step-by-step explanation:

If we set up our equation using the unknown number of hot dogs and corn dogs with their individual prices attached to them, we can set the sum of them equal to $201.  We know that a hot dog costs $3, so we can represent hot dogs monetarily by attaching the cost of a single hot dog to the h.  For example, if a hot dog costs $3, and we represent the expression as 3h, with h being the number of hot dogs sold, if we sell 4 hot dogs at $3 apiece, we make $12.  If we sell 6 hot dogs we will make $18.  The same goes for the corn dogs.  We don't know how many corn dogs or hot dogs we sold, but we do know that the sales of both made $201.  So our expression for that is

3h + 1.50c = 201

That's great, but we have too many unknowns, and that's a problem.  So let's look back up to where we are told that the number of hot dogs is 3 less than 2 times the number of corn dogs.  "3 less than" is -3 algebraically.  "Twice the number" is 2times  and the words "is" and "was" represent the = sign.  So putting those words into an algebraic equation looks like this:

h = 2c - 3

That says "the number of hot dogs was twice the number of corn dogs less 3".  Now that we have an expression for hot dogs we can sub it into our money equation in place of h:

3h + 1.5c = 201 becomes 3(2c - 3) + 1.5c = 201

Now we have an equation with only c's in it.  

Distribute through the parenthesis to get

6c - 9 + 1.5c = 201

Simplify to 7.5c = 210

Now divide by 7.5 to get that c = 28.

Now that we know that, we go back with that number and sub it in for c in

h = 2c - 3 -->  h = 2(28) - 3 gives us that the number of hot dogs sold was 53

The total number of corn dogs sold is 28 corn dogs and number of hotdogs is 53

let

h = number of hotdogs

c = number of corndogs.

cost of hotdog = $3

corn dog = $1.50

The equation:

3h + 1.50c = 201 (1)

h = 2c - 3 (2)

substitute (2) into (1)

3(2c - 3) + 1.50c = 201

6c - 9 + 1.50c = 201

7.50c - 9 = 201

7.50c = 201 + 9

7.50c = 210

c = 210/7.50

c = 28

Therefore,

h = 2c - 3

= 2(28) - 3

= 56 - 3

= 53

[tex]C=2\pi r =2\pi10=20\pi\approx\boxed{62.8}[/tex]

The answer is D.

The circumference of a circle with a radius of 10 inches is approximately 62.8 inches, calculated using the formula C = 2πr, resulting in the answer choice D. 62.8.

To calculate the circumference of a circle when the radius is given, we use the formula C = 2πr. Given that the radius (r) of the circle is 10 inches, we can calculate the diameter (d) as 2×10 inches, which equals 20 inches. Now, we multiply the diameter by π (approximately 3.1416) to find the circumference:

C = πd = 3.1416 × 20 inches = 62.832 inches.

Based on standard rounding rules, this is approximately 62.8 inches. Thus, the correct answer is D. 62.8 square inches.

26 different outcomes include at least two heads.

There are [tex]26[/tex] different outcomes that include at least two heads when a coin is tossed [tex]5[/tex] times.

The total number of outcomes when a coin is tossed [tex]5[/tex] times is [tex]\(2^5 = 32\)[/tex], since each toss has [tex]2[/tex] possible outcomes (heads or tails).

To find the number of outcomes with at least two heads, we can find the total number of outcomes with exactly one head and no heads, and subtract that from the total number of outcomes.

1. Number of outcomes with no heads: There is only [tex]1[/tex] outcome with no heads ([tex]5[/tex] tails).

2. Number of outcomes with exactly one head: This can be calculated using combinations. There are [tex]5[/tex] ways to choose which toss will be heads, and for each of these, the remaining [tex]4[/tex] tosses must be tails. So, there are [tex]\(5 \times 1 = 5\)[/tex]outcomes with exactly one head.

Therefore, the number of outcomes with at least two heads is:

Final answer:

The probability that a student takes theatre given that the student is taking choir is found using conditional probability and is calculated to be 0.3, or 30%.

Explanation:

To find the probability that a student takes theatre given that the student is taking choir, we use the definition of conditional probability. In this scenario, the probability of a student taking theatre and choir (joint probability) is given as 0.078, and the probability of a student taking choir (marginal probability) is 0.26.

The formula for conditional probability is:

P(A | B) = P(A and B) / P(B)

Let A represent the event of a student taking theatre, and B represent the event of a student taking choir. Substituting the given values into the formula yields:

P(A | B) = 0.078 / 0.26

Performing the division gives us:

P(A | B) = 0.3

Therefore, the probability that a student takes theatre given that the student is taking choir is 0.3, or 30%.

Step-by-step explanation:

This may look daunting, but let us approach it step by step.

multiply 1/10 by x - 3

0.1x - 0.3 = -40

In algebra, the goal is always to undo all the operations and get back to the original problem so that the mystery value can be determined. In this case since 0.3 was removed, we must add it back.

0.1x = -39.7

0.1x/0.1 = x

39.7/0.1 = -397

Answer seems to be B. -397, but we should still check it.

0.1(-397) - 0.3 = -40

-39.7 - 0.3 = -40

-40 = -40 Correct

If the answer was incorrect, this would show that there had been a flaw in our calculations. But everything checks out, so we are done!
