First off, remember PEMDAS. Then replace the variables with the values.
3(2x3)^2
First distribute the exponent to the value on the inside.
3(4x9)
Then multiply the 4 and 9.
3(36)
After that just distribute the 3.
3x36 = 108.
Answer:
129 1/6 feet
Step-by-step explanation:
Formula for area is L*W
1. convert the mixed numbers to improper fractions
12 1/2 feet = 25/2
10 1/3 feet = 31/3
2. multiply numerator by numerator (25*31 = 775
3. multiply denominator by denominator (2*3=6
4. convert improper fraction 775/6 into a mixed number by dividing 775 by 6.
5. 775/6 = 129 r. 1 or 129 and 1/6
L = 2 W
B = L x W = 2 W²
Side Area = 2 W H + 2 L H = 2 H ( W + L ) = 6 H W
V = 2 W² H = 10
H = 5 / W²
Cost = 15 * 2 W² + 9 * 5/W
= 30 W² + 270/ W
C ` = 60 W - 270 / W²
= ( 60 W² - 270 ) / W² = 0
60 W² = 270
W ² = 270 : 60
W² = 4.5
W = √ 4.5 = 2.12
Cost (min) = 15 * 2 * 4.5 + 30 / 2.12 = 135 + 14.15 = $149.15
Answer: The cost of materials for the cheapest such container is $149.15.
Answer:
I WRITE THE STEPS
Step-by-step explanation:
Find the Equation of a Line Given That You Know a Point on the Line And Its Slope. The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept. If you a point that a line passes through, and its slope, this page will show you how to find the equation of the line.
