the percentage = area(parallelogram)/area(rectangle).100
so
percent = (4.7)/(6.10).100 = 140/3= 46.6
Answer:
the numbers are 77 and 79
Step-by-step explanation:
so the 2 numbers are
x and x+2
so
x+x+2=156
subtract 2 from both sdies
2x=154
divide by 2
x=77
The trousers will cost $48.
60 / 100 = 0.6
20% off so that will make it 80% of 60 so you put the two together by doing:
0.6 * 80 = 48
The expression to be simplified is: (9x^2 - 25) / (3x + 5)
We first factor the numerator: 9x^2 - 25 is a difference of two squares, (3x)^2 - (5)^2, so this can be factored into (3x + 5)(3x - 5).
Then the expression becomes (3x + 5)(3x - 5) / (3x+5), and the 3x + 5 term cancels out, leaving just 3x - 5 as the final answer.
Steve will earn $160 interest after four years ⇒ 1st answer
Step-by-step explanation:
The formula of the simple interest is I = Prt, where
- P is the initial deposit
- r is the annual rate in decimal
- t is the time of investment
∵ Steve opens a bank account with a simple annual interest rate of 5%
∴ r = 5% = 5 ÷ 100 = 0.05
∵ His initial deposit is $800
∵ He will put the money for four years
∴ t = 4
- Substitute all these values in the formula above
∵ I = 800(0.05)(4)
∴ I = 160
Steve will earn $160 interest after four years
