972 represent the total population of the rabbits after five yours. 
Answer: B
Andrei [34K]3 years ago
4 0

Answer: Second option is correct.

Step-by-step explanation:

Since we have given that

The population of a species of rabbit triples every year is expressed as

f(x)=4(3)^x

Here, Initial population = 4

Rate of growth = 3

Number of years = x

So, we have f(5)=972=4(3)^5

So, it means 972 is the population of the rabbits after 5 years.

Hence, Second option is correct.

Suppose that the perimeter a rectangle is 54 feet, and the length is 13 feet more than the width. Find the width ractangle, in f
Vesnalui [34]

Answer:7feet

Step-by-step explanation:

perimeter(p)=54ft

Width(w) +13=Length(L)

Perimeter=2xLength+2xwidth

P=2xL+2xw

L=w+13

54=2(w+13)+2w

54=2w+26+2w

Collect like terms

54-26=2w+2w

28=4w

Divide both sides by 4

28/4=4w/4

7=w

Width =7feet

A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. She knows that Solution A is
Yuri [45]

Answer:

x= 44 ounces y = 66 ounces  

Step-by-step explanation:

Distribution would be an increase to find 80% salt.

Where we use 4/5 = 80 but use here 4/5.

We find 19/20 but just say 95 for solution B =

Let x = the number of ounces of Solution A

Let y = the number of ounces of Solution B

x + y = 110        y = 110 - x

(70x + 95y) = 4/5 x 110

70x + 95y = 88    

70x + 95 y = 88

70x + 95 (88 - x) = 8800 make units equal or for start convert decimalization = same units as 2nd multiplied value.

70x + 8360 - 88x = 8800

-10x - 8360 - 8800 = y

-10x = 440

x = 44 ounces

y = 110- 44

y =  66 ounces
