Answer:
option B
$28.80
Step-by-step explanation:
Given the question,
side length of one square tile = 9 inches
area of square tile = l² = 9² = 81 inches²
<h3>Step1</h3>
There are 48(96) = 4608 carpet tiles, so the company was making 4608($.05) = $230.40.
<h3>Step2 </h3>
Now, the company countered with square feet. We have a total of 4608(81) = 373,248 square inches.
1 square foot = 144 square inches.
373,248/144 = 2592 square ft.
2592($.10) = $259.20
$259.20 - $230.40 = $28.80
Simplify just means put together everything into one big thing. In this case that is just adding. To add a fraction and a decimal we have to convert the fraction into a decimal as well. The decimal form of 1/4 is 0.25, and as such, 3/4 is .75. This means we have -0.75+1.5. Adding a positive to a negative is the same thing as simply subtracting the first number from the second, or 1.5-0.75. This is .75. The answer is C.
Answer: the value of the account at the end of 6 years is is $8577
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = 6000
r = 6% = 6/100 = 0.06
n = 4 because it was compounded 4 times in a year.
t = 6 years
Therefore,.
A = 6000(1+0.06/4)^4 × 6
A = 6000(1+0.015)^24
A = 6000(1.015)^24
A = $8577
Why?
Because if you draw a line from A to D to make a triangle AED, then triangle all angle add up equal 180.
