Just did this one.
The perimeter is the sum of the sides.
n + (3n - 4) + (3n - 5) = 33
7n - 9 = 33
7n = 42
n = 6
3n-4=18-4=14
3n-5=13
Check: 6+14+13=33, good
Answer: 6 cm, 14 cm, 13 cm
When using scientific notation, the number (that is not 10 to the nth power) is always between 1 and 10.
For 772,000.0, I've added the decimal to the correct place. In order to get a number between 1 and 10, we will need to move the decimal 5 places. This leaves us with 7.72 x 10^5.
But, as I see that the answer above is not an option, and the only correct answer would be A, It is the only one between 1 and 10, I feel that there may be a mistake. For A to be correct, the original number would be 7,720,000,000.
Best answer: A
Hope this helps!! :)
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.
Answer:
348 out of 725
Step-by-step explanation:
This is a ratio question, giving us a sample that we can use to extend the number to all students.
12/25 students play a sport so we want the value of x in x/725
So:
12/25 = x/725
Cross-Multiply:
25x = 8700
Divide by 25 to get x:
348
You can also check by dividing these ratios to see if you get the same number. In this case, you do (.48).
