Answer:
Area of one face of the cube is 
Step-by-step explanation:
A cube is a three dimensional figure that has all of its sides equal.
A cube has six square faces:
Surface area of the cube = 
where 'a' is the side length of the cube:
Area of one face of a cube= 
For surface area of the whole cube: 500 square inches

Dividing by '6' both sides;


Area of one face of the cube is 
Answer:
-1280
Step-by-step explanation:
10, -20, 40, -80, 160, -320, 640, -1280
The pattern of the sign is positive, negative, positive, so the 8th term is negative. Then the rule is times 2.
Answer:
7, 11, 29
Step-by-step explanation:
2233 divided by 7, 11, 29, gives no remainder. They are integers and prime numbers of 2233, they are also called composite number. Prime number are numbers that can divide without remainder, This means that 2233 is divisible by 7, 11, 29, numbers.
Answer: $1040
A = P + I
A = Total
P = Principal
I = Interest
First find the total amount
A = 640(4)(9)
A = 23040
Plug In the Numbers
23040 = 22000 + I
Substract 22000 on both sides
I = $1040
Answer:
after 3 months, both plans cost the same amount
Step-by-step explanation:
- Let x is the number of months
- Let y is the total cost
Given the following information:
<u>Plan 1: pay $20 per month, plus a $60 signing fee </u>
=> the equation for this plan is:
y1 = 20x+60
<u>Plan 2: pay $40 per month plus no signing fee </u>
=> the equation for this plan is:
y2 = 40x
To find number of months will both plans cost the same amount, we need to set the equation of plan 1 = equation of plan 2
<=> y1 = y2
<=> 20x+60 = 40x
<=> 20x = 60
<=> x = 3
So after 3 months, both plans cost the same amount
