Answer:
$2,812.50
Step-by-step explanation:
Let
y ----> amount that Sarah earn this month
x ----> amount of sales over $5,750
we know that
5%=5/100=0.05
The linear equation that represent this situation is
y=4(525)+0.05(x)
Find the value of x
x=20,000-5750=$14,250
substitute
y=4(525)+0.05(14,250)=$2,812.50
Any perpendicular line has a negative reciprocal slope. So your slope would be 2. The. You would have the equation : y=2x+b. You would then replace the coordinate (5,6) with x and y on your line to solve for b. Your equation would be : y=2x-4
1. To solve this problem you need to apply the formula for calculate the surface area of a square pyramid, which is shown belown:
A=2bs+b^2
A is the surface area of the square pyramid.
b is lenght of the base of the square pyramid.
s is the slant height of the square pyramid.
2. Then, you have:
b=2.7 inches
s=2.5
3. When you substitute the values above into the formula for calculate the surface area of the square pyramid, you obtain:
A=2bs+b^2
A=2(2.7 inches)(2.5 inches)+(2.7 inches)^2
A=13.5 inches^2+7.29 inches^2
A=20.79 inches^2
The answer is: 20.79 inches^2
