Answer:
so Area = length x width
Area = 450, width = 9
450 = 9 x length
divide 450 by 9, and you have the length.
Perimeter = length + length+ 9 + 9
and you got your perimeter!

Find the range of the data.
67, 63, 72, 62, 64, 79, 74, 66
Answer:
The range is 17
Step-by-step explanation:
67, 63, 72, 62, 64, 79, 74, 66
To find the range of the data, take the largest number and subtract the smallest number.
The largest number is 79
The smallest number is 62
79-62 = 17
The range is 17

A new car sells for $34,500. If the car depreciates at a rate of seven and a half percent each year, how much will the car be worth in five years?
Answer:
$23356.5
Step-by-step explanation:
Given data
Cost = $34,500
rate= 7.5%
Time= 5 years
The expression for the depreciation is
A= P(1-r)^t
substitute
A= 34500(1-0.075)^5
A= 34500(0.925)^5
A= 34500*0.677
A=$23356.5
Hence the worth will be $23356.5

Un parallélépipède rectangle posé sur une de ses faces carrées a un volume de 252cm cube, il a une hauteur de 7. Quelle est la longueur du coté de la base carré
Répondre:
6 cm
Explication étape par étape:
Volume du parallélépipède rectangle V = l²h
l est la longueur du carré basé
h est la hauteur
Étant donné
V = 252 cm³
h = 7 cm
Remplacer
252 = l² (7)
252 = 7l²
l² = 252/7
l² = 36
l = √36
l = 6 cm
D'où la longueur du côté de la base carrée est de 6 cm
Isaac owes \$8,100$8,100 on his credit card. The bank charges an annual interest rate of 21.9%, compounded monthly. If Isaac wants to pay off his credit card using equal monthly payments over the next 16 months, what would the monthly payment be, to the nearest dollar?
Answer:
[tex]M=\$605.58[/tex]
Step-by-step explanation:
From the question we are told that:
Issac's Debit [tex]P=\$8100[/tex]
Annual interest rate [tex]r=21.9\%[/tex]
Number of payments [tex]n=16[/tex]
Generally the equation for Monthly payment is mathematically given by
[tex]M=\frac{Pr}{1-(1+r)^-^n}[/tex]
[tex]M=\frac{1800*0.0219}{1-(1+0.0219)^-^{16}}[/tex]
[tex]M=\$605.58[/tex]
Therefore Payment for each month is given as
[tex]M=\$605.58[/tex]

inches is added to the height, how much more
sand can it hold?
HELP PLASSS!!!
A. 12 ft
B. 15Ft
C: 17.5 ft
D. 21 ft
Answer:
C. 17.5
Step-by-step explanation:
The current volume of the sandbox is 7×5×1 = 35 feet³
If six inches is added to the height, the new volume will be 7×5×1.5=52.5
To find the difference in how much the snadbox can hold, you can subtract. 52.5-35= 17.5

Your salary is $105,000 per year
Each month, 16% of your income is deducted for taxes?
7. What is your after-tax monthly income?
9514 1404 393
Answer:
$7350
Step-by-step explanation:
The tax deduction multiplies your income by 1 -16% = 84%. The expression of it as a monthly amount multiplies it by 1/12. So, your monthly take-home income is ...
$105,000(0.84)(1/12) = $105,000(0.07) = $7,350
Your after-tax monthly income is $7350.

Answer:
Area = 0.785 yrd
Circumference = 12.56 yrd
Step-by-step explanation:
Diameter = 1 yrd
Area of a circle = pi times the radius squared
A = 3.14 (1/2)^2
A = 0.785
Circumference of a circle = 2 times pi times the radius
C = 2(3.14)(1/2)
C = 12.56
