Answer:
3y+4+2y+16=180 sum of two opposite angle of the cyclic quadrilateral is 180
5y=180-20
y=160/5=32
again
2x+58=180sum of two opposite angle of the cyclic quadrilateral is 180
2x=180-58
x=122/2=61
Answer:
17 in.
Step-by-step explanation:
There are two same angles shown, so two sides are equal. We can form an equation x+4=4x+1. Solution is x=1, then both unknown sides are 5 in. long. Given all side lengths we add them 7+5+5+15 getting the perimeter.
Given:
May painted 4 out of 8 equal parts of a poster board is blue.
Jared painted 2 out of 4 equal parts of the same sized poster board red.
May: 4/8 = 1/2 of the poster board.
Jared: 2/4 = 1/2 of the poster board.
The fractions are equal. Since the poster board is of the same size, both May and Jared painted equal parts which is 1/2 of the poster board.
The 8 and 4 only indicate the number of equal parts that are drawn on the poster board.
<em>Answer,</em>
<em><u>4a^3 − 10a + 6/3a^2</u></em>
<em>Explanation,</em>
<em><u>Just Simplify</u></em>
<em>= 16a^4 − 40a^2 + 24a/12a^3</em>
<em>= 16a^3 − 40a + 24/12a^2</em>
<em>= </em><em>4a^3 − 10a + 6/3a^2</em>

Answer:
81 million
Step-by-step explanation:
A = Pe^rt
Let's break this equation down.
A is the total you will have.
P is the starting value.
R is the rate
T is the time.
Let's find the rate first.
74000000 = 70000000e^7r
Divide each side by 70mil
74000000/70000000 = e^7r
Then take the ln() of each side.
ln(74000000/70000000) = 7r
0.0556 = 7r
r = 0.0079
Now we can find how many people will be there in 2010.
A = 70,000,000e^(19 * 0.0079)
A = 81336530.2373
Now we round to the nearest million, leaving us with 81 million.
