i took the quiz
B.) 2x − 60
C.) 5x + 60
D.)2x − 60
Answer:
The answer is C. 5x + 60
Step-by-step explanation:
The number whose 50 percent is 90 is 180.
We have,
Equation:
Number x 50% = 90
And,
50% = 50/100 = 0.5
Divide both sides of the equation by 50%
Number = 90 / 0.5
Number = 180
Cross-checked the number.
50% of 180
= 50/100 x 180
= 0.5 x 180
= 90
Therefore,
The number whose 50 percent is 90 is 180.

paintbrush is dropped from a height of
100 feet. The polynomials represent the
heights (in feet) of the objects after
t seconds.
-16t²- 40t + 200
-16t² + 100
a. Write a polynomial that represents the distance between the penny and the
paintbrush after 7 seconds.
b. Interpret the coefficients of the polynomial in part (a).
Answer:
7.5 yards
Step-by-step explanation:
Since the area of a triangle is found by the equation: , in which b=base h=height, and is base times height, we can work backward from the value of the area to find the height of the park
Start by multiplying 7500 by 2. From this, you get 15000.
Now for the second step, you have to divide 15000 by 2000 in order to determine the height of the triangle. this value comes out to 7.5.
This means that the values of the equation are b=2000 and h=7.5
To double-check, we multiply 2000 by 7.5. and divide that value by 2. This gives us the original area of 7500
This means that the height of the park is 7.5 yards
