Answer:
Step-by-step explanation:
- When 1 gallon is has been used 400 square feet of the wall will be paint
- The unit rate is 400 square feet per gallon
The function modelled by the height (x) of the tree is as follows:
y - 180 = (368 - 180)/(7 - 3) (x - 3)
y - 180 = 47(x - 3) = 47x - 141
y = 47x - 141 + 180 = 47x + 39
Therefore, after 10 years, the tree will be 47(10) + 39 = 470 + 39 = 509 cm tall

Answer:
If 32 students are enrolled in the course, there would be 24 girls.
Step-by-step explanation:
Given that For every boy in an advanced math course there are 3 girls who are taking the course.
It means if there are four students in the class. There would be 3 girls and 1 boy. Thus, 75% of the students are girls.
Given that there are 32 students enrolled in the course.
so
75% of 32 = 75/100 × 32
= 24
Thus, if 32 students are enrolled in the course, there would be 24 girls.
Answer:
$20,000 = sales
Step-by-step explanation:
Giving the following information:
Fixed salary= $300
Commission rate= 1% of sales
<u>First, we need to establish the net income formula:</u>
Net income= 300 + 0.01*sales
<u>Now, the sales required for $500 net income:</u>
500= 300 + 0.01sales
200/0.01 = sales
20,000 = sales
Prove:
Net income= 300 + 0.01*20,000
Net income= $500
