Using proportions, the cheapest option for Alisa to purchase enough sand to fill the court is Option A, which will cost $8.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
For each option, the cost per pound is
- Option A: 12/150 = $0.08.
- Option B: 5/60 = $0.0833.
Option A is cheaper, hence the total cost for 100 pounds is:
$0.08 x 100 = $8.

To be a function, the DOMAIN, the X-COORDINATE, and the INPUT VALUES cannot repeat.
For example, the coordinates (3,6) and (5,6) are good, but if you were to have the coordinates (3,7) and (3,9), that would not be a function.
Answer:
17. C 60°
18. D 121°
Step-by-step explanation:
The external angle is half the difference of the intercepted arcs.
17. (161° -41°)/2 = 60°
__
18. (? -59°)/2 = 31°
? = 59° +2(31°) = 121°
The answer is 25000 hope this help you out!
Answer:
Step-by-step explanation:
Move constant to right hand side and change it's sign
⇒
Add the numbers
⇒
<u>Let's </u><u>check</u><u>:</u>
When d = 15 , R.H.S = 15 - 7 = 8
And L.H.S = 8
Thus , R.H.S = L.H.S when d = 15.
Therefore d = 15 is the solution of the equation.
