Step-by-step explanation:
Q1
Finding amount of money of the interest (2.5%)
5000 × 0.025 = $125 per year
Since he left the money in for 10 years
125 × 10 = $1250
Add that with the original amount of money
1250 + 5000 = $6250
Q2
Finding the amount of money of the charge (4.5%)
45000 × 0.045 = $2050 year
Since she has been paying off the loan for 20 years
2050 × 20 = $40500
Add that with the original loan to find the amount that she has to pay in TOTAL
40500 + 45000 = $85500
Answer:
The surface area increases by 4 times
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared
Let
z -----> the scale factor
x ----> the surface area of the new rectangular prism
y ---> the surface area of the original rectangular prism
so
we have
----> because is doubled
substitute and solve for x
----> surface area increases by 4 times.
The correct option is D): "an=1/n" because:
<span>since first term: n is 1,
if you plug in 1 in the 1/n,
you get one.
second term: n=2,
so, 1/n = 1/2.</span>
54-6 = 48
48/4 (Alex-twice, Jennifer, Shannon)
48/4= 12
Alex- 12 x 2 = $24
Jennifer- 12 = $12
Shannon- 12+6 (the 6 I subtracted 54-6) = $18
It’s the last one! Hope this helps
