Answer:
4
Step-by-step explanation:
If each of 12 kids ate 1/3 of a pizza, the amount eaten was ...
12 × 1/3 pizza = 12/3 pizza = 4 pizza
Dominic needed to buy 4 pizzas.
1) The dependent variable is the total cost.
2) The perimeter is 36 inches.
The dependent variable is the one that gets changed by the other one. In this case, the total cost gets changed by the amount of fabric bought.
To find the perimeter:
Since the ratios of the side length to perimeter is the same, we set up the ratio:
2/8 = 9/x
Cross multiply:
2*x = 8*9
2x = 72
Divide both sides by 2:
2x/2 = 72/2
x = 36
44 because the absolute values are 131 and 87 and to find difference you subtract.
Answer:
Each print costed $1.92.
Step-by-step explanation:
First you'll need to divide 25 and 13
Equation: 25/13= 1.92307692
Well remove all the numbers after the number 92. and you'll get that 92.
So the answer is $1.92.
Answer:
13
Step-by-step explanation:
(x + 3)^3/2 = 64
√(x + 3)^3 = 64
(x + 3)^3 = 64^2
(x + 3)^3 = (4^3)^2
(x + 3)^3 = (4^2)^3
Same exponent
So
x + 3 = 4^2
x + 3 = 16
x = 13
