Answer:

$s=5.1$

Step-by-step explanation:

We have been given an equation $0.7(3s+4)-1.1s=7.9$ . We are supposed to solve the given equation.

Using distributive property $a(b+c)=ab+ac$ , we will get:

$0.7(3s)+0.7(4)-1.1s=7.9$

$2.1s+2.8-1.1s=7.9$

$2.1s-1.1s+2.8=7.9$

$1.0s+2.8=7.9$

$s+2.8-2.8=7.9-2.8$

$s=5.1$

Therefore, the solution for the given equation is $s=5.1$ .

The diameter of a cylinder is 3yd the height is 8yd

nalin [4]

Answer:

volume= 56.55 yds

Step-by-step explanation:

If you're looking for the volume, the formula is $V=\pi r^{2} h$ .

Diameter is two times the radius (radius is half of the diameter) so the radius of the cylinder would be 1.5 yds.

After you've gotten that information, plug those values into the formula.

$V=\pi 1.5^{2} 8$

Solve 1.5^2 first. Then multiply that value by pi. Then multiply that value by the height which is 8yds.

Volume=56.55yds rounded to the nearest hunderedth.

Answer:

h(2) = 11

Step-by-step explanation:

To evaluate h(2), substitute x = 2 into h(x), that is

h(2) = 5(2) + 1 = 10 + 1 = 11
