Jermaine earned $2000 during the summer. He plans to put the money in a
savings account and leave it for 40 years. The account will earn 9% simple
interest annually. What will the balance be after 40 years?
Please help!! This is a test and I need a good grade!!
Answer:9200
Step-by-step explanation: .09 * 2000 = 180 * 40 = 7200 + 2000 = 9200
Balance amount in Jermaine account after 40 years is equals to $9200.
What is simple interest?" Simple interest is the process of calculating amount of interest given on the principal amount at the rate of interest over period of time."
Formula used
S.I. = = (P × R × T) / 100
S.I.= Simple Interest
P = Principal amount
R = Rate of interest
T = Time
Total amount = P + S.I.
According to the question,
Given
P = $2000
R = 9%
T = 40 years
Substitute the given values in the formula we have,
Simple Interest = (2000 × 9 × 40) / 100
= $7200
Total balance amount after 40 years = $2000 + $ 7200
= $9200
Hence, balance amount after 40 years is equals to $9200.

Answer:
37.50 square centimeters
Step-by-step explanation:
The computation of the area of the sector is as follows:
As we know that
Area of the circle is
= πr^2
Since the radius is 10 cm so the area of total circle is
= 3.14 × 100
= 314
Also it is 360 degrees
So, the area of the sector is
= 135 ÷ 360 × 1200
= 37.50 square centimeters

* Brittany's teacher tells her that she did well on the Statistics test - her z-score was 1.80 on the test. If the mean score on the test was a 75 with a standard
deviation of 10, find Brittany's score
Answer:
93
Step-by-step explanation:
Given that:
Brittany's Zscore = 1.8
Mean score (m) = 75
Standard deviation (s) = 10
Brittany's score (x) =?
Using the Zscore formula :
Zscore = (x - m) / s
1.8 = (x - 75) / 10
18 = x - 75
18 + 75 = x
93 = x
Hence, Brittany's score is 93

Answer:
a) The equation of V and W
V = k W
b) The value of V = 666.6
Step-by-step explanation:
Step(i):-
Given that V is inversely proportional to W
V∝ W
⇒ V = k W
⇒ 40 = k (0.9)
⇒ [tex]k = \frac{40}{0.9} = 44.44[/tex]
Step(ii):-
Given that W = 15 and k = 44.44
we have to find the value is 'V'
V = k W
⇒ V = 44.44 × 15
⇒ V = 666.6
