Answer:
Surface area of the refrigerator is 864 in².
Step-by-step explanation:
Formula to calculate the surface area of a cube is,
Surface area = 6s²
Here, s = length of a side of the cube
If side length 's' = 12 inches
By substituting this value in the formula,
Surface area = 6(12)²
= 6 × 144
= 864 inch²
Therefore, surface area of the refrigerator is 864 in².
Idk what the ! are for but i would thing the answer is 2...
Answer:
61 years old
Explanation:
You can solve this using an equation. The equation I’m going to use is:
500 - 4x = 256
x will represent the age we are trying to find, so now we will solve to x.
500 - 4x = 256
(- 500 from both sides of the equation)
-4x = -244
(➗-4 on both sides)
x = 61
brainliest plz? :)

Answer: a) Equation y= 20+ 1.50n.</h3><h3>b) Melia have $644 to spend on her 18th birthday.</h3>
Step-by-step explanation: We are given that Melia put $20 initially in piggy bank.
Each week amount added in piggy bank = $1.50.
Let us assume total number of weeks be n Melia added amount in piggy bank and get y amount after n weeks.
a) Therefore, total amount after n weeks = Initial amount + 1.50 times n weeks.
y= 20+ 1.50n.
b) On 18th birthday, there would be total 8 years after 10th birthday.
And in 8 years there would be 52 × 8 = 416 weeks.
So, in order to find the total amount after 8 years or 416 weeks, we need to plug n= 416 in the equation we got in a part.
Therefore,
y = 20+ 1.50(416)
y = 20 + 624 = 644.
<h3>Therefore, Melia have $644 to spend on her 18th birthday.</h3>
