Answer:

90

Step-by-step explanation:

Measure of one arc = 90°

-> Measure of other arc = 360°- 90° = 270°

x° = 1/2 (270° - 90°)

-> x° = 1/2 * 180°

-> x° = 90°

-> x° = 90°

-> x = 90

Answer: 462 yards ^3

Step-by-step explanation:

The equation for the volume of a cylinder is πr^2h

the diameter is 7 yards and the radius is just half the diameter so the radius is 3.5

the height is 12 yards

so π(3.5)^2(12) = 461.814120078 yards ^3

Answer:

I believe the answer is 13.5

Step-by-step explanation:

because u need to find the area of a triangle which is Area= b*h*0.5 so fill in the blank b=9 h=3 b*3*0.5=13.5

Answer:

D). 19.5

Step by step answer:

Bigger triangle:

4 + 5 = 9 (Base)

Height = 3

A = 9 x 3 / 2 = 13.5

Smaller triangle:

Height = 3

Base = 4

A = 4 x 3 / 2 = 6

6 + 13.5 = 19.5

Answer:

25.65634 squares cm

Step-by-step explanation:

The area of the whole circle is

pi x 7 squared

pix49 =153.93804

the degrees of a circle are 360

 60 is 1/6 of 360

so we need to divide the area by 6

153.93804/6 = 25.65634

Answer:

x = 6 , y = 2

Step-by-step explanation:

81x + 10 = 5y + 486 ............ (1)

9x + 40 = 20y + 54 ............ (2)

(1) × 4 - (2)

315x = 1890

x = 6 -------> (2)

9(6) + 40 = 20y + 54

20y = 94 - 54

y = 2

How do you solve a rectangle word problem?

The area A of a rectangle is given by the formula, A=lw , where l is the length and w is the width. Given that, the area is 500 square feet and the width is 20 feet. So, substitute these values into the formula. Divide each side by 20 to isolate l .

Let's see

Answer:

A

Step-by-step explanation:

it is a 90 degree angle so you have to figure out what something plus 10 equals and then multiply the x by 2 so basically it's a solve and answer or redo it until you get 90° for your total

(i dont know what you mean by that cause clearly just do 194 - 177 = 17 pounds)

Round 194 pounds to 190 ; 177 to 180

In estimation, Pedro's book weighs 190 - 180 = 10 pounds more.
190 : 180 = 1.06 times more.

Answer:

The distance between Vega 3 and the Mars (MV) illustrates cosine function, and the distance is 29.1 million light years or 142.8 million light years

From the question, we have the following parameters

See attachment for the illustration of the given parameters.

The distance between Vega 3 and the Mars (MV) is then calculated using the following cosine function

VS² = MS²+ MV² - 2 * MS * MV * cos(Ф)

This gives

4489 = 8649+ MV² -  171.96MV

Subtract 8649 from both sides

MV² -  171.96MV = -4160

Rewrite as:

MV² -  171.96MV + 4160 = 0

Using a graphing tool, we have:

MV = 29.1 and MV = 142.8

Hence, the distance between Vega 3 and the Mars is 29.1 million light years or 142.8 million light years

Answer:

They are the same size.

Step-by-step explanation:

Radius is one half the diameter meaning our diameter is twice as large as our radius. So (diameter)/2 = radius or 2*radius= diameter. So since the radius of circle r is 7 inches, that means its diameter is 14 inches. If the diameter of circle k is 14 inches, that means its radius is 7 inches.

This problem has two variables, b and y. The b value is the number of rows of blue flowers, and the y value is the number of rows of yellow flowers.

In every row of blue, there are 5 flowers.

In every row of yellow, there are 7 flowers.

Therefore, our expression would be 5b + 7y.

I hope this answers your question.

Answer:

It is translation

the car stays the same when it moves from BLUE to B"L"U"E"

Step-by-step explanation:

if it was a rotation, the car would be upside-down in the final product.

if it was a reflection, the car would also be upside-down.

if it was a dilation the final product would be smaller.

This is how we know is a translation.
