Remember, "mean" means the average of the numbers.
In order to find an average, add all the numbers together, then divide by the amount of numbers.
So:
1+5+7+9+11+16+18+20+30+35=153
Since there are 10 numbers in the sequence, divide by 10.
153/10=15.3
Answer:
P=50
Step-by-step explanation:
First use the formula for perimeter which is P = 2l + 2w. Then plug in to find your answer.
STEPS:
P = 2l + 2w
P=2(13)+2(12)
P=26+24
P=50
The equation is provided below:
x = cost of DVD player
3x = cost of the movies
$532 = total amount purchased for the DVD player and the movies
$532 = x + 3x
$532 = 4x
$532 / 4 = 4x / 4
$133 = x (cost of the DVD player)
$133 * 3 = $399 (cost of the movies)
To check if the equation is correct:
$532 = $133 + ( 3 * $133)
$532 = $133 + $399
$532 = $532
The correct answer for the cost of the movies will be $399.
Answer:
4072
Step-by-step explanation:
I don't have any other loan terms to see, so i will assume that it's over a period of 10 years compounded at interest of 5%. If its not, you can just use the process I use to calculate the other loan terms cost.
So, you plug in the values. We know the final amount, A is equal to the original amount P, 2500, and the time is 10 years.
So A = 2500(1 + 0.05)^10 which equals 4072
