Answer:
157.78
Step-by-step explanation:
Area of a trapezoid = ( sum of base lengths / 2 ) × height
the base lengths of the trapezoid shown are <u>8.7m</u> and 16.3 + 7.2 = <u>23.5m</u>
the height is <u>9.8m</u>
so area = (( 8.7 + 23.5 ) / 2) × 9.8
==> add 8.7 and 23.5
area = (32.2 / 2) × 9.8
==> divide 32.2 by 2
area = 16.1 × 9.8
==> multiply 16.1 and 9.8
area = 157.78
Answer:
72 Wrong, so find how many are right with 135 total
Step-by-step explanation:
It's similar to saying if she answered half and this continued how many would she have answered after answering a bigger number, you would say half.
so she answered 8/15 incorrectly a a smaller number, so she will answer that ratio with a bigger number. If it helps 8/15 is about 53%. just like 1/2 is half. So to find half you would multiply something by 1/2 and int he same way you multiply something by 8/15 to get that proportion of it.
so 135, if you take this 53%, or simply multiply it by 8/15 you get your answer of 72. So 72 wrong so al others are right, which you get with 135-72 = 63.
You could also do 135*(1-8/15) = 135 * 7/15. if you ever want to find something NOT part of the proportion you do 1 - that proportion.
Nope sorry I am but not very good
To determine her miles per hour, you will first convert her pace of 0.08 commoners per minute to a number of kilometers per hour.
0.08 x 60 = 4.8 km per hour
Next convert her rate of 4.8 commoners per hour to a number of miles per hour.
4.8/1.61 = 2.99 Miles per hour

Answer:
25 and 20
Step-by-step explanation:
p²=24²+7² ⇒ p²= 625 ⇒ p=25
q²=p²-15² ⇒ q²=625 - 225 ⇒ q²=400 ⇒ q= 20
