Zoe has $24 in a savings account. The interest rate is 5% per year and is not compounded. How much will she have to save in 4 ye
umka2103 [35]

Answer:

$28.8

Step-by-step explanation:

First we need to get the interest on the savings for the 4years. Since it is not compounded, we will use the simple interest (SI) formula.

According to the simple interest formula, SI = Principal × Rate × Time/100

Give principal = $24 rate = 5℅ time = 4years

SI = 24×5×4/100

SI = 480/100

SI = $4.8

Zoe interest for four years will be $4.8.

Amount she has saved for 4years = principal + interest = $24+$4.8

= $28.8

Lkm is equilateral. Solve for x if angle k=9x+24
Marta_Voda [28]

Answer:

x = 4

Step-by-step explanation:

Given that the triangle is equilateral then the measure of each angle is 60°

Equate 9x + 24 to 60 and solve for x

9x + 24 = 60 ( subtract 24 from each side )

9x = 36 ( divide both sides by 9 )

x = 4

Piper has a points card for a movie theater. she receives 60 rewards points just for signing up. she earns 13.5 points for each
Arisa [49]

Answer:

10

Step-by-step explanation:

I first took away 60 from 195, as she already had 60 points. Than we were left with 135 points and since she gets 13.5 points every time she visits, I divided 135 by 13, which gives us 10.
