In the problems A-F, You multiply each of the numbers by itself. Like 9²=9×9=81
3³=3×3×3=27 6³=6×6×6=216 and so on for the other problems
G-I is 36=6² 100=10² and so on the cube is the same except you multiply the number three times by itself. I hope this helped a bit. Just ask if you still don't understand.
Answer:
230 cm squared
Step-by-step explanation:
Split the shape into a triangle and a rectangle
The area of a triangle is base x height / 2
20 x 9= 180/2= 90 (9 because you do 16-7 to find height of triangle)
Find the area of the rectangle=
7 x 20= 140
Add them up
140+90= 230cm squared

It should be 18, because despite of 3,14, because that's pi and radius is half of the diameter, so36 divide 2 is 18.
The mass of the first shipment at time t is
The mass of the second shipment at time t is
At time t, the ratio of m₁ to m₂ is
Therefore as a percentage,
Answer: B. 81.2%
Pinpoint the ten's place.
look at the one's place. It is a digit ≥5, round up. If it is digit <5, round down.
all the digits to the right of the ten's place becomes 0.
for example, if you are given $216.23, the ten's place is a 1. Look at the number to the right of it, the one's place is a 6, bigger than 5, so you round up, the 1 becomes a 2. the result is $220.00
if you are given $214.23, the 1 stays a 1 because 4 is smaller than 5, the result is $210.00
