Answer:
1)42
2)400
3)$2000
Step-by-step explanation:
Q1)
- 35% = 35/100 = 7/20 (simplify)
- (7/20)×120 = 42
Q2)
- Let number = $
- 60% = 60/100 = 3/5
- (3/5)×$ = 240
$ = 240 ÷ (3/5)
= 240 x (5/3)
= 400
Q3)
- Let number = #
- 40% = 40/100 =2/5
- (2/5)×# = $800
# = $800 ÷ (2/5)
= $800 × (5/2)
= $2000

Answer: 125.6 cm³
Step-by-step explanation:
1. To solve this problem you must apply the formula for calculate the volume of a cylinder:
Where h is the height and r is the radius.
2. Therefore, you only need to substitute the values of the radius and the height into the formula, as you can see below:
3. Then, the answer is: 125.6 cm³.
Answer: The function that modeled the expected population is: F(y) = 200 ( 1.07) ^y
Step-by-step explanation:
It's important to note that according to our problem, y is the input value in years and x is the output value of the deer population.
Let's begin by stating the general form of an exponential equation and explaining the meaning of each variable in the equation:
f(y) = A(B)y
f(y) = output value of x for input value of y
A = initial output value of x
(when input value of y = 0)
B = multiplier (percentage rate)
y = any input value of y
Given : y = 1
A = present population of dear= 200
B= percent increase multiplier = 1 + 7% = 1 + 0.07 = 1.07
F(y) = x = A (B) ^y
F(y) = 200 ( 1.07) ^ 1
