Paulita is going to build a storage cube. Each edge is 14 inches. The wood costs $0.03 per square inch. Use 0.03(5e2) , where e is the edge length, to evaluate for e = 14 . (1 point)
To evaluate for e = 14, we substitute 14 for e in the expression 0.03(5e^2):
0.03(5(14)^2) = 0.03(5(196)) = 0.03(980) = 29.4
Therefore, the expression evaluates to 29.4.
Miss Yang has bulletin boards of different sizes in her classroom. She wants to calculate how much border she needs for each one. The length of each bulletin board is 6 inches less than three times its width, w . Simplify w + 3w − 6 + w + 3w − 6 to find the formula for the perimeter of each of Miss Yang’s bulletin boards.(1 point) Responses 6w2 − 10 6 w squared minus 10
To find the formula for the perimeter of each bulletin board, we need to simplify the expression w + 3w - 6 + w + 3w - 6:
This simplifies to 10w - 12.
Therefore, the formula for the perimeter of each bulletin board is 10w - 12.
To evaluate the cost of the wood for the storage cube, we are given the formula 0.03(5e^2), where e is the edge length.
Substituting e = 14 into the formula, we get:
0.03(5 * 14^2)
Now, we can simplify the equation:
0.03(5 * 196)
0.03(980)
Finally, we can calculate the value:
0.03 * 980 = $29.40
Therefore, the cost of the wood for the storage cube with each edge measuring 14 inches would be $29.40.
To evaluate the expression 0.03(5e2) for e = 14, we need to substitute the value of e into the expression.
First, let's simplify the expression 5e2.
5e2 = 5 * (e^2) = 5 * (14^2) = 5 * 196 = 980
Now, we can substitute the simplified value of 980 into the expression 0.03(5e2).
0.03(5e2) = 0.03 * 980 = 29.4
Therefore, when e = 14, the value of the expression 0.03(5e2) is $29.4.
