Answer:
$507.30
Step-by-step explanation:
-Given the monthly deposits are $425 and the interest rate is 3.5% for 30 years.
-The amount of the investment after 30 years is calculated as;
-Assuming Saul started saving at age 20, his investment term will be 40 yrs.
-His investment amount is thus:
#We subtract to find how much more he would have if he started saving at 20;
Hence, Saul would have $507.30 more had he started saving 10 years earlier.
Answer:
Step-by-step explanation:
7) The formula for determining the area of a parallelogram is expressed as
Area = base × height.
Length of base = Area/height
Therefore,
Length of base = 7/2 = 3.5 feet
8) The formula for determining the area of a trapezoid is expressed as
Area = 1/2(a + b)h
Where
a and b are the length of the bases
h is the height. Therefore
21 = 1/2(2 + 4)h
21 = 3h
h = 21/3 = 7 inches
9) Area = base × height.
Height = Area/Length of base
Height = 28/14 = 2 inches
10) a and b are 10 inches each.
Area = 1/2(a + b)h
Therefore,
35 = 1/2(10 + 10)h
35 = 10h
h = 35/10
h = 3 inches
Answer:
The equation that can be used to find the missing number is 96 - 12n = 3 + n
Step-by-step explanation:
The difference of 8 less a number n
This is 8 - n
Multiplied by twelve
This is:
12(8 - n) = 96 - 12n
Is equal to 3 more than the number.
96 - 12n = 3 + n
The equation that can be used to find the missing number is 96 - 12n = 3 + n
