Simply substitute the given number for all the equations.

17) 5b + 1 = 16 where b is -3

5(-3) + 1 = 16

-15 + 1 = 16

-14 ≠ 16

So, the given number is not a solution.

19) 2 = 10 - 4y where y is 2

2 = 10 - 4(2)

2 = 10 - 8

2 = 2

The given number is a solution.

21) -6b + 5 = 1 where b is 0.5

-6(0.5) + 5 = 1

-3 + 5 = 1

2 ≠ 1

The given number is not a solution.

A farmer wants to build a new grain silo. The shape of the silo is to be a cylinder with a hemisphere on the top, where the radi

notsponge [240]

Answer:

The radius of the silo should be $16\ ft$

Step-by-step explanation:

we know that

The volume of the grain silo is equal to the volume of the cylinder plus the volume of a hemisphere

$V=\pi r^{2} h+\frac{4}{6}\pi r^{3}$

we have

$V=35,500\pi\ ft^{3}$

$h=4D=8r$

substitute the values and solve for r

$35,500\pi=\pi r^{2} (8r)+\frac{4}{6}\pi r^{3}$

Simplify

$35,500=r^{2} (8r)+\frac{4}{6}r^{3}$

$35,500=8r^{3}+\frac{2}{3}r^{3}$

$35,500=\frac{26}{3}r^{3}$

$r^{3}=35,500*(3)/26$

$r=16\ ft$

Step-by-step explanation:

Given:

The<u> radius </u>of the base of a metallic rod is<u> 2 centimetres</u>, and its<u> height is 15 centimetres.</u>

Question asked:

What is the<u> volume </u>of this cylinder?

<u>Solution</u>:

As we know''

$Volume\ of\ cylinder=\pi r^{2} h$

$=\pi \times2\times2\times15\\ \\ =60\pi$

Answer:

B.

Step-by-step explanation:

Again taking proportionality between their any two sides as the two triangles as considered separate are similar

AB/AC=AD/AE

4/6=7/AE

cross Multiplying

4×AE =6×7

AE=42/4

AE=10.5
