Answer:
-6634
Step-by-step explanation:
(5m)² - (2n-3m)³ if m=-3 and n=5
= (5 * (-3))^2 - (2 * 5 - 3 * (-3))^3
= (-15)^2 - (10 - (-9))^3
= 225 - (19)^3
= 225 - 6859
= -6634

Answer:
B: 24ft^2
Step-by-step explanation:
Area of triangle = (base x height)/2
Step 1: form an equation
a = (12ft x 4ft)/2
Step 2: solve equation
a = 48ft^2 / 2
a = 24ft^2
*the base is the measurement for the bottom of a triangle while height is the measurement of the length from the bottom to the top of a triangle*
Answer:
Percent change = 5.4%
Step-by-step explanation:
Given:
Number of students voted last year = 762
Number of students voted this year = 721
Change in the number of students who voted from last year to this year is given by the difference of their number. This gives,
Change in the number of students that voted = 762 - 721 = 41
Now, percentage change in the number of students that voted is given as:

Therefore, the percent change in the number of students that voted is 5.4%.
