12 out of 20 are full.
Divide full by total cans and then multiply by 100:
12/20 = 0.6 x 100 = 60 %
Answer: 60% are full
Answer:
<u>Perimeter
</u>
Step-by-step explanation:
Draw the polygon to have an idea of what you are being asked.
<h3>See picture attached
</h3>
Now find the length of each side and add them up, that is the perimeter.
To find the length of a side use the formula of the distance between to points (a,b) and (c,d)
<u>Distance between (-2,1) and (-3,3)
</u>
<u>Distance between (-3,3) and (-1,5)
</u>
<u>Distance between (-1,5) and (2,4)
</u>
<u>Distance between (2,4) and (2,1) (obviously 3)
</u>
<u>Distance between (2,1) and (-2,1) (obviously 4)
</u>
Add up all the lengths
<u>Perimeter
</u>
Step-by-step explanation:
Factor out two from the expression. The answer should be 2(2*(-2, 3)-(6, -7))
2 is C but I dunno about 1
Step-by-step explanation:
Sin<D = Opposite / Hypotenuse
Opposite - EC
Hyp - DE
Sin<D = EC/DE = x/9
we need x to find <D.
so -->Use pythagorean theorem.
DE^2 = EC^2 + DC^2
DE = 9 DC = 7 EC = ?
EC^2 = DE^2 - DC^2 rearranged.
= 9^2 - 7^2
= 81 - 49
EC^2 = 32 Put both sides under square root.
√(EC^2) = √32
EC = 4√2 ~ 5.65.
We now have X which was representing the unknown side EC.
Sin<D = EC/DE = 5.65/9 = 0.627
To find <D Take the sine inverse of of 0.627.
<D = Arcsin(0.627) = 38.82°.
We now know <D. It's <E's turn.
A right angle triangle has a summation of interior angles of 180°.
thus, <em><D + <C + <E = 180°</em>
38.82° + 90° + <E = 180°
128.82° + <E = 180°
subtract both sides by 128.82°
0 + <E = 180° - 128.82°
<em><E = 51.</em><em>2</em><em>°</em>
