Let's start by identify a 30-60-90 triangle

If we compare those two traingles we can stablish the following relation:

\begin{gathered} a\sqrt[]{3}=6\sqrt[]{3} \\  \end{gathered}

Therefore, a=6

u is the opposite side to the 90° angle, therefore

\begin{gathered} u=2a \\ u=2\cdot6 \\ u=12 \end{gathered}

on the other hand, v is the opposite side to the 30° angles, so

\begin{gathered} v=a \\ v=6 \end{gathered}

xz_007 [3.2K]

Step-by-step explanation:

1. radius=13in

diameter= 2r =2(13)=26in

area=πr²= 22/7*(13)²

531.14in²

circumference= 2πr=2*22/7*13

81.71in

2.radius=32ft

diameter= 2r =2(32)=64ft

area=πr²= 22/7*(32)²

3218.28ft²

circumference= 2πr=2*22/7*32

201.14ft

I'm pretty sure the answer is D. because I don't think anyone would want to take their total meal cost and then multiply it by their tip to make it even larger. You would just add the tip to the meal cost.

8.1 liters to meters
Wittaler [7]

The US equivalent of "liters to meters" would be something like
"quarts to yards", which is equally meaningless.

Liters and meters don't even measure the same thing.  Liters describe
volume, whereas meters describe length or distance.    They don't convert
to each other .

If volume units could be converted to length units, then you (or somebody
with a slightly better grasp of his math) would be able to figure out how many
inches of gas he put into his car last week, and the cost of a foot of milk.

Levart [38]

Answer:

Subtracting 7

Step-by-step explanation:

<u><em>Given:</em></u>

<em>Clara is stacking cups; she put 45 plastic cups in the first stack, 38 plastic cups in the second stack, 31 plastic cups in the third stack, and 24 plastic cups in the fourth stack. </em>

<u><em>To Find:</em></u>

<em>What kind of sequence is this?</em>

<u><em>Solve:</em></u>

<em>Let's make a table:</em>

<em />

<em>[1 stack]  45 </em>

<em>[2 stack] 38</em>

<em>[3 stack] 31</em>

<em>[4 stack] 24</em>

<em />

<em>Now all we have to do is subtract to see what each is:</em>

<em>45 - 38 = 7</em>

<em>38 - 31 = 7</em>

<em>31 - 24 = 7</em>

<em>Thus,</em>

<em>[1 stack]  45 ⇒ 7</em>

<em>[2 stack] 38 ⇒ 7 </em>

<em>[3 stack] 31 ⇒ 7 </em>

<em>[4 stack] 24 ⇒ 7 </em>

<em>Hence, each stack is going down by 7.</em>

The interior angles of a triangle add up to 180 degrees, meaning we can make an equation.

2x+36=180

2x=144
