first transform feet into inches 4.5 feet = 48.5 inches; 5.5 feet = 60.5 inches;
then get the area in inches : 48.5 x 60.5 = 2934.25 inches; the area of one patch is 18 x 24 = 432 inches
so now divide the area of the desktop by the area of one patch
2934.25 / 432 = 6.7 so she needs 7 patches
He can because you can add it mentally. You can just have 23 in your head and count by adding 10 "4" times.
Hope this helped☺☺
Answer:
Step-by-step explanation: A on edge
Sum of geometric sequence
for the sum where the initial value is a₁ and the common ratio is r and the term is n
common ratio is -3
-5 times -3 is 15, -15 times -3=-45 etc
first term is -5
and we want the 8th term
the sum is 8200
Answer:
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the loan.
P represents the principal or amount taken as loan
R represents interest rate
T represents the duration of the loan in years.
1) From the information given,
P = cost of gym = $2200
R = 6%
T = 3 years
I = (2200 × 6 × 3)/100 = $395
The total amount that he would pay after 3 years is
2200 + 395 = $2596
If he decides to continue going to the gym, the total amount that the would pay in 3 years(3 × 12 = 36 is
80 × 36 = 2880
Therefore, paying for the gym would cost more. He should take the loan.
2) if she takes the loan, the interest would be
I = (18000 × 7.5 × 5)/100 = $6750
The total amount that she would pay back after 5 years is
6750 + 18000 = $24750
Since the value that would be added to her house is $25000, therefore, she should buy it.
