At the start of the year, the balance in a married couple’s account is $ 1 , 750 . They decide to each deposit $ 35 into the acc
Dimas [21]

Answer:

f(n) = 1750 + 70n

Step-by-step explanation:

Since, each of them are depositing 35$ each month, they are adding 35x2 = 70$ each month.

So, in n months, they will be adding 70n $ to their account.

Initially, they had 1,750$ in their account. After n months, they should have 1750+70n $ in their account.

So, the function that represents this is, f(n) = 1750 +70n

Rachel traveled to five different areas (A, B, C, D, and E) to study the number of buckeye butterflies and the number of monarch
Ivenika [448]

Answer:

As we can see our our ration in Area B and Area D gives the same answer, so they are in proportion

Step-by-step explanation:

Given that

Rachel traveled to 5 areas to find  number of Buckeye and Monarch butterflies.

Areas Rachel Traveled to = A, B, C, D, E

The table given below shows her findings.

Area            Buckeye          Monarch

A                     15              16  

B                      27              36  

C                     12              25  

D                      24              32  

E                      44              33

Now lets find the ratio of Buckeye and Monarch Butterflies in these areas

Area A

Buckeye : Monarch = 15:16 = 0.9375

Area B

Buckeye : Monarch = 27:36 = 0.75

Area C

Buckeye : Monarch = 12:25= 0.48

Area D

Buckeye : Monarch = 24:32 = 0.75

Area E

Buckeye : Monarch = 44:33 = 1.334

As we know that if two ratios give same answer after solving the fraction then these ratios are in proportion.

As we can see our our ration in Area B and Area D gives the same answer, so they are in proportion.
