Yes, because if two angles of a triangle are equal, then the third angle must also be equal, because angles of a triangle always add to make 180°.

Which situation is represented by the equation? 6n + 12 = 2n + 36
Romashka [77]
<span>6n+12=2n+36
We move all terms to the left:
6n+12-(2n+36)=0
We get rid of parentheses
6n-2n-36+12=0
We add all the numbers together, and all the variables
4n-24=0
We move all terms containing n to the left, all other terms to the right
4n=24
n=24/4
n=6</span>

Answer:

h(-6) = -\frac{1}{5}

Step-by-step explanation:

Given

h(x) =\left[\begin{array}{cc}8 + 6x\ \ &x < -7\\\frac{x + 4}{10} &-7 \le x

Required

Determine h(-6)

To do this, we make use of:

h(x) = \frac{x + 4}{10}

Because -7 \le -6

So, we have:

h(x) = \frac{x + 4}{10}

h(-6) = \frac{-6 + 4}{10}

h(-6) = \frac{-2}{10}

Simplify

h(-6) = -\frac{1}{5}

For the senior pic mr. Williams is using two cylinders to help keep the food cool the inside still there with the radius of 8 in
Rasek [7]
The answer is  1,695.6 in³.

The volume of the empty space is the difference of the bigger cylinder and the smaller cylinder: V = V1 - V2

The volume of the bigger cylinder is:
V1 = π r² h
r = 10 in
h = 15 in
π = 3.14

V1 = 3.14 * 10² * 15 = 4,710 in³


The volume of the smaller cylinder is:
V2 = π r² h
r = 8 in
h = 15 in
π = 3.14

V2 = 3.14 * 8² * 15 = 3,014.4 in³


The volume of the empty space is:
V = V1 - V2 = 4,710 in³ - 3,014.4 in³ = 1,695.6 in³
