Answer:
30 units^2
Step-by-step explanation:
The area of a trapezoid is
A = 1/2 (b1+b2)h
The scale is 2 units per line
b1 = 2 units
b2 = 8 units
h = 6 units
A = 1/2 ( 2+8) * 6
= 1/2 (10)6 = 30 units^2
-First we have to work out what’s in parenthesis.
(8*10^-3)=(8*0.001)=0.008
-This is for the second parenthesis
(2*10^-4)=(2*0.0001)=0.0002
-Now we multiply them together
ANSWER: 0.0000016
<h3>
Answer: $628 </h3>
==========================================================
Work Shown:
x = Ali's share
4x = Pip's share, because it is four times bigger due to the ratio 4:1
x+4x = 5x = total amount of money = 785
5x = 785
x = 785/5
x = 157 dollars is Ali's share
4x = 4*157 = 628 dollars is Pip's share
Note that 157+628 = 785 to help confirm the answer.
