Answer:

Step-by-step explanation:

So first, you find the area of a rectangle, which would be 15 * 30 = 450. Next, find the area of the semicircle by doing $\pi *r^2 / 2$ (you have to divide by 2 because it's only have a circle).

The radius is half of 15, so 15 / 2 = 7.5. This would be:

$\pi * 7.5^2 / 2$

$=\pi * 56.25 /2$

$=28.125\pi$

$=28.125*3.14=88.3125$

The last step is to add 450 + 88.3125 = about 538.3 m^2

Answer:

1st ans

(8x+19)=(9x+9)(vertically opposite angle)

19-9=9x-8x

x=10

2nd ans

(3x-31)=(x+59)(exterior alternate angle)

3x-x=59+31

2x=90

x=90/2

x=45

3rd ans

(5x-33)+(6x+4)=180(straight angle )

11x-29=180

11x=180+29

x=209/11

x=19

angel's dad bought a television for her completing all of her digital learning day lesson. he want to warp the gift. the box mea

atroni [7]

Answer: 13 sheets of paper

Step-by-step explanation:

We are given the dimensions of the box and the wrap paper:

Box:

$(56 in)(8 in)(36 in)$

Warp paper:

$(26 in)(17 in)$

Now we need to find the surface area of the box and the area of the wrap paper:

Box:

$surface_{1}=(56 in)(8 in)(2)=896 in^{2}$

$surface_{2}=(8 in)(36 in)(2)=576 in^{2}$

$surface_{3}=(56 in)(36 in)(2)=4032 in^{2}$

$surface-area=896 in^{2}+576 in^{2}+4032 in^{2}=5504 in^{2}$

Warp paper:

$area=(26 in)(17 in)=442 in^{2}$

Dividing the area of the box by the area of the paper:

$\frac{surface-area}{area}=\frac{5504 in^{2}}{442 in^{2}}=12.45 \approx 13$

This means Angel's dad needs to purchase 13 sheets of wrapping paper.

If x is 1 what is the value of y?9x - 5y = 29

mylen [45]

Given

The equation,

9x - 5y = 29.

To find the value of y when x is 1.

Explanation:

It is given that,

$9x-5y=29$

That implies,

When x=1,

$\begin{gathered} 9(1)-5y=29 \\ 9-5y=29 \\ -5y=29-9 \\ -5y=20 \\ y=\frac{20}{-5} \\ y=-4 \end{gathered}$

Hence, the value of y is -4.
