Answer:

27.3 (C)

Step-by-step explanation:

First, add 68 and 26 to get 94.

Subtract 94 from 180 (The measure of a triangle.)

You will get 86.

Subtract 4, to get 82.

Divide by three.

I hope this helps!

A rocket is launched from atop a 65-foot cliff with an initial velocity of 113 ft/s. The height of the rocket above the ground a

OlgaM077 [116]

Answer:

7.6 seconds

Step-by-step explanation:

To solve this problem we can use the following equation:

S = So + 113*t + at^2/2

Where S is the final position, So is the inicial position, Vo is the inicial speed, a is the acceleration and t is the time.

In this problem, we have that S = 0, So = 65, Vo = 113 and a = -32 ft/s2 (The acceleration of gravity)

So we have that:

0 = 65 + 113t - 16t2

16t2 - 113t - 65 = 0

Using Bhaskara's formula, we have:

Delta = 113^2 + 4*65*16 = 16929

sqrt(Delta) = 130.11

t = (113 + 130.11) / (2*16) = 7.597 seconds

Rounding to nearest tenth, we have t = 7.6 seconds

A cylinder is placed within a cube. The diameter of the cylinder is equal to the length of each side of the cube. What is the vo

pochemuha

The volume of a shape is the amount of space in it.

<em>The volume outside the cylinder, but inside the cube is 214.6 cubic inches</em>

The given parameter is:

$l = 10$ ---- length of the cube

So, the volume of the cube is:

$V_1 = l^3$

$V_1 = 10^3$

$V_1 = 1000$

The volume of the cylinder is:

$V_2 = \pi r^2h$

The diameter (d) of the cylinder equals the length of the cube.

This means that:

$d = l$

$d = 10$

Divide by 2 to calculate the radius of the cylinder

$r = \frac{10}{2}$

$r = 5$

Also, the height of the cube is::

$h =l$

$h =10$

So, we have:

$V_2 = \pi r^2h$

$V_2 = \pi \times 5^2 \times 10$

$V_2 = \pi \times 25 \times 10$

$V_2 = \pi \times 250$

$V_2 = 785.4$

So, the volume (V) outside the cylinder is:

$V = V_1 - V_2$

$V = 1000 - 785.4$

$V = 214.6$

Hence, the volume outside the cylinder is 214.6 cubic inches
