Answer:
<u>Trapezoid area:</u>
- A = 1/2(a + b)h, where a, b - bases , h - height
<h3>17. a)</h3>
- a = RS = 4 units
- b = AT = 8 units
- h = 8 units, the distance between RS and AT
A = 1/2(4 + 8)*8 = 48 units²
<h3>17. b)</h3>
- a = SK = 4 units
- b = OC = 10 units
- h = SO = 6 units
A = 1/2(4 + 10)*6 = 42 units²
<h3>18. a)</h3>
- a = ME = 6 units
- b = AZ = 10 units
- h = MA = 8 units
A = 1/2(6 + 10)*8 = 64 units²
Answer:
b is the answer
Step-by-step explanation:
Hey there!
We can set up an equation. Since 20% is said as twenty percent, we can conclude that it says "per-cent", which means "per hundred", like century is a hundred years. That way, we can say that 20% is also written as a decimal of twenty hundredths, because it's per hundred. Thus, we're saying that his down payment, 1,600, is (this is keywording for equals) 20% of (keyword for multiplication) the total price (x). That gives us:
1,600 = .20x
Divide both sides by .20
x = 8,000
Therefore, the cost of the car was 8,000 dollars.
Hope this helps!
