Answer:

y = -5

Step-by-step explanation:

To solve this, we simply plug in 4 into x and then solve for y. We have:

[tex]-3x+9y=-57\\[/tex]

Now we put 4 into x and do some algebra and solve for the value of y:

[tex]-3x+9y=-57\\-3(4)+9y=-57\\-12+9y=-57\\9y=-57+12\\9y=-45\\y=\frac{-45}{9}\\y=-5[/tex]

So y = -5

I believe it is 45 studs to the end of the wall

Answer:

Step-by-step explanation:

First, convert 20 yds to 60 ft. and then from 60 ft to 720 in.

Use the formula for the nth term of an arithmetic sequence:

l = a + (n-1)d:

Here l = 720 ft, and a = 0.  The common difference, d, is 16 in.  Our task is to determine how many studs are needed.

Substituting the knowns, we get 720 = 0 + (n - 1)(16), which simplifies to:

720 = (n-1)(16).

Divide both sides by 16 to isolate (n-1):  45 = n - 1.

Adding 1 to both sides results in 46 = n.

46 studs total are needed; if the worker has already placed the first stud, then 45 additional studs are needed.

The ratio is how much something has, comparative to another thing.

So, for every 10 apples, there are 4 oranges (first blank). Therefore, if there is half, five, of the apples, there are two (second blank), half of four, oranges. And, if the number of oranges tripled (12), there will be triple apples, which is 30 (third blank).

Answer: 10:4, 5:8, 1:12

Step-by-step explanation:

So for apples it goes my 10 then to 5 right? So the next one must be 1

For orange the first number they gave u is 4 and the 3rd number is 12. If u look in the multiplication table it goes like 4,8,12, ect.

Answer:

2727

Step-by-step explanation:

The formula for finding the volume of a cone is

1/3πr²h

The radius would be 11.5 because, radius equals the diameter divided by two.

So, first you would plug your numbers into the equation

1/3(π)(11.5)²(19.7)

*use 3.14 for pi

Then multiply.

V = 2726.9 (2727 if you round to the nearest whole number)

Where’s The Expressions?

Answer:

n  = 30

Step-by-step explanation:

The triangles share the same angle measures, so they are similar triangles.  The side lengths of similar triangles are proportional to each other, so we can set up a proportion and solve for n...

16 is to 20 as 24 is to n

16/20 = 24/n       now solve for n by cross multiplying

16n = 480

     n = 30      (divide both sides by 16)

We are given that the original triangle and its projection are similar. This means that the corresponding angles of the two triangles are congruent, and the ratios of their side lengths are equal.

We are also given the lengths of two sides of the original triangle: 16 cm for the base and 20 cm for the hypotenuse. We are asked to find the missing length on the projection, which corresponds to the base of the original triangle.

To solve this problem, we can set up a proportion based on the similar triangles. Let x be the missing length on the projection:

(base of original triangle) / (base of projection) = (hypotenuse of original triangle) / (hypotenuse of projection)

Substituting the known values:

Cross-multiplying:

Therefore, the missing length on the projection is 19.2 cm. However, the answer choices are all rounded to one decimal place.

Rounding 19.2 cm to one decimal place gives us 19.0 cm. Therefore, none of the provided options are correct.

Answer:

Price of the drink = $1.25

Step-by-step explanation:

4.5% * ( $4.5 + $6.25 + drink) = $0.54

4.5/100 * ( $4.5 + $6.25 + drink) = $0.54

0.045 * ( $4.5 + $6.25 + drink) = $0.54

0.045/0.045 * ( $4.5 + $6.25 + drink) = $0.54/0.045

( $4.5 + $6.25 + drink) = $12

10.75 + drink = $12

drink = $12 - $10.75

drink = $1.25

The price of the drink is $1.25

The given parameters are:

Tax amount = $0.54

Salad = $4.50

Sandwich = $6.25

Let the price of the drink be x.

Given that the sales tax is 4.5%, we have:

4.5% * ( $4.5 + $6.25 + x) = $0.54

Divide both sides by 4.5%

( $4.5 + $6.25 + x) = $12

Evaluate the sum

$10.75 + x= $12

Subtract $10.75 from both sides

x = $1.25

Hence, the price of the drink is $1.25

Answer:

y = - [tex]\frac{1}{4}[/tex] x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

To calculate m use the slope formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (4, 6) and (x₂, y₂ ) = (- 4, 8)

m = [tex]\frac{8-6}{-4-4}[/tex] = [tex]\frac{2}{-8}[/tex] = - [tex]\frac{1}{4}[/tex], hence

y = - [tex]\frac{1}{4}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 4, 8 ), then

8 = 1 + c ⇒ c = 8 - 1 = 7

y = - [tex]\frac{1}{4}[/tex] x + 7 ← equation of line

That is the lowest value = 12

The lowest value in a box-and-whisker plot is the minimum of the dataset. For the given data set, the lowest value, which is the minimum, is 10.

The student is asking us to find the lowest value represented in a box-and-whisker plot. A box-and-whisker plot is a graphical representation of a five-number summary of a dataset: the minimum, first quartile (Q1), median (Q2), third quartile (Q3), and the maximum. The lowest value in a box-and-whisker plot is the minimum of the dataset.

To graph a box-and-whisker plot for the given data values, you would first need to arrange the data in ascending order. Then, find the minimum, Q1, median, Q3, and the maximum. The smallest number, which is placed at the leftmost part of the plot, is the minimum, also known as the lowest value of the dataset. For the data set provided (10, 10, 10, 15, 35, 75, 90, 95, 100, 175, 420, 490, 515, 515, 790), the lowest value is 10.

Replace t with 1 through 4 and solve then add them together:

6^(1-1) = 6^0 = 1

6^(2-1) = 6^1 = 6

6^(3-1) = 6^2 = 36

6^(4-1) = 6^3 = 216

Sum = 1 + 6 + 36 +216 = 259

Answer:  The required sum is 259.

Step-by-step explanation:  We are given to find the sum of the following geometric series :

[tex]\sum_{i=1}^{4}6^{i-1}.[/tex]

The given geometric series can be written as :

[tex]0+6+6^2+6^3.[/tex]

We know that

the sum of a geometric series up to n terms with first term a and common ration r is given by

[tex]S=\dfrac{a(r^n-1)}{r-1}.[/tex]

in the given series, we have

[tex]a=1,~~r=\dfrac{6}{1}=\dfrac{6^2}{6}=\dfrac{6^3}{6^2}=6.[/tex]

Therefore, the sum up to 4 terms will be

[tex]S_4=\dfrac{a(r^4-1)}{r-1}=\dfrac{1(6^4-1)}{6-1}=\dfrac{1296-1}{5}=\dfrac{1295}{5}=259.[/tex]

Thus, the required sum is 259.

Answer: this is the first ones answer is D.

The second answer will be C.

Option: C is the correct answer.

The equation of the blue graph i.e. function G(x) is:

               C.  [tex]G(x)=(x+3)^2+1[/tex]

We are given a parent function F(x) as:

                      [tex]F(x)=x^2[/tex]

Now after looking at the graph of the transformed function G(x) we see that the graph of G(x) is obtained by shifting the graph of F(x) 3 units to the left and  1 units upward.

Hence, the equation of the transformed function G(x) is given by:

                           [tex]G(x)=(x+3)^2+1[/tex]

Answer: D. 648*π in^3

Step-by-step explanation:

The formula for the volume of a cylinder is

[tex]V=\pi *r^2*h[/tex]

V=1130.973355 in^3

or simply

V=1130.97 in^3

or

V=360*π  in^3

Since, you know the radius of the hemisphere on top, you also know the radius since the height of the hemisphere is the same as it is wide.

Next, the formula for the volume of a sphere is

[tex]V=\frac{4}{3} \pi *r^3[/tex]

since you have two hemispheres, its the same thing as solving for one sphere because two halves make a whole. So, the volume of the sphere is

V= 904.7786842 in^3

or simply

V= 904.78 in^3

or

V=288 *π  in^3

Finally, you add both of the volumes together to get

V= 2035.75204 in^3

or simply

V= 2035.75 in^3

or

V= 648*π  in^3

Answer:

1. The area of regular pentagon = 292.5 inches²

2. The area of the regular octagon = 80 cm²

3. The area of the regular hexagon = 126 feet²

Step-by-step explanation:

∵ The area of any regular polygon = 1/2 × perimeter × apothem

1. Regular pentagon

∵ Regular pentagon has 5 equal sides

∵ The perimeter of the regular pentagon = 5 × side length

∵ S = 13 inches

∴ P = 13 × 5 = 65 inches

∵ apothem = 9 inches

∴ A = 1/2 × 65 × 9 = 292.5 inches²

2. Regular octagon

∵ Regular octagon has 8 equal sides

∵ The perimeter of the regular octagon = 8 × side length

∵ S = 4 cm

∴ P = 4 × 8 = 32 cm

∵ apothem = 5 cm

∴ A = 1/2 × 32 × 5 = 80 cm²

3. Regular hexagon

∵ Regular hexagon has 6 equal sides

∵ The perimeter of the regular hexagon = 6 × side length

∵ S = 7 feet

∴ P = 7 × 6 = 42 feet

∵ apothem = 6 feet

∴ A = 1/2 × 42 × 6 = 126 feet²
