A function is a set of ordered pairs in which no two different ordered pairs have the same x -coordinate.
Btw you need to add an image so we can see which the order pairs
To answer this youd have to set up a proportion. 5/2 is the ratio of weight on earth and mars respectively. The other side has to have the same ratio where 125lbs is the weight on earth and x is the weight on mars. The equation would look like 5/2=125/x. Youd have to cross multiply, and would get (125)(2)=5x. Solve for x to find the weight on mars
Answer:
#3
<u>What was the area left unpainted?</u>
Option D
#4
<u>How big is Ben's share?</u>
- 998.50 - 18.6² = 652.54 m²

#5
<u>The area of a circular pool whose radius is 2 m:</u>
- A = π² = 3.14*2² = 12.56 m²
Option A
So he has to paint 255 m from the 280 m of paint he has
First divide 255/280 to give you a decimal
You should get .9107
Since this is in decimal form (out of 1) you want to get percentage which is out of 100 you multiply by 100
So .9107 times 100
This gives you the percentage which is
91.07%
Now it says round to 1 decimal so it would be
91.1%
