Rule: with any inscribed quadrilateral, the opposite angles are supplementary (they add to 180 degrees)
Based on that rule, we can say
d+100 = 180
d+100-100 = 180-100
d = 80
Answer: 80
- Simplify ⇨ 19m + 14 - 3 (3m + 7)
Use the distributive property to multiply -3 by 3m+7.
Combine 19m and -9m to get 10m.
Subtract 21 from -14 to get -35.
Answer:
40 % off
Step-by-step explanation:
First you are going to 1.30, then divided that by 0.80
I got 2,500 left after 5 years.
10,000*15% = 1,500 or you could do 10,000*.15 = 1,500
That is a loss of 1,500 fish per year.
If you want to think of this as a proportion then you would do
Year/fish lost
1/1,500 = 5/x
X=5*1,500
X=7,500
The population of the fish after 5 years equals
10,000-7,500 = 2,500
So your answer is 2,500 fish are left
Water in the swimming pool initially = 2.5 million liters
Water in the swimming pool after evaporation = 2 million liters
Therefore, volume of water evaporated = 2.5 million liters - 2 million liters
=0.5 million liters
To find the percent of water evaporated, divide the volume of water evaporated by the volume of water in the swimming pool initially and then multiply it by 100.
Percent of water evaporated =( 0.5 / 2.5) x 100 =20%
