The value of the angle shown in the protactor is 50° and the value of y is 10°.

<h3>How to calculate the values?</h3>

The value of y will be:

2y + 30 = 3y + 20

3y - 2y = 30 - 20

y = 10

The value of x when they're complementary will be:

5x - 2 + 3x + 4 = 90

8x + 2 = 90

8x = 90 - 2

8x = 88.

x = 88/8 = 12

The value of angle FDE will be:

3x + 10 + 6x + 8 = 180

9x + 18 = 180

9x = 180 - 18

9x = 162

x = 162/9

x = 18

FDE = 6x + 8

= 6(18) + 8

= 108 + 8

= 116

PLEASE HELP: The mass of a ball is 128 g. It has a density of 0.5 g/cm³. What is the volume of the ball? Show your work and plac

tiny-mole [99]

Answer:

Part 1) The volume of the ball is 256 cm³

Part 2) The radius of the ball is 3.94 cm

Step-by-step explanation:

Part 1) we know that

The density is equal to divide the mass by the volume

D=m/V

Solve for the volume

The volume is equal to divide the mass by the density

V=m/D

In this problem we have

m=128 g

D=0.5 g/cm³

substitute

V=128/0.5=256 cm³

Part 2) what is the radius of the ball?

we know that

The volume of the sphere (ball) is equal to

$V=\frac{4}{3}\pi r^{3}$

we have

$V=256\ cm^{3}$

assume

$\pi =3.14$

substitute and solve for r

$256=\frac{4}{3}(3.14)r^{3}$

$768=(12.56)r^{3}$

$r^{3}=768/(12.56)$

$r=3.94\ cm$

Write an expression that represents n plus 7 multiplied by 3.

diamong [38]

The <span>expression that represents n plus 7 multiplied by 3 is
(n + 7)(3)
The entire expression, (n + 7) is multiplied by 3 since it would be inconvenient to state the expression as given above if what is meant was
(n + 7x3). It would have simply been n plus 21.</span>
