Answer:
where is the figure and the picture?
Answer:
1) 100 ) 15
Step-by-step explanation:
1) 30 to 50 is 20 miles so 5 * 20 is 100
2)20 to 50 is 30 miles so its 150 and 15 to 20 is 5 so 11 *5 is 55
55+150 equals 250 so the answer is 15 miles.
Let x = the width
then
2x = the length
:
The box dimensions: 2x by x by 4
Given the surface area:
2(2x*x) + 2(2x*4) + 2(x*4) = 220
:
4x^2 + 16x + 8x = 220
A quadratic equation:
4x^2 + 24x - 220 = 0
simplify, divide by 4
x^2 + 6x - 55 = 0
Factor
(x+11)(x-5) = 0
The positive solution is what we want here:
x = 5 ft is the width
then
2(5) = 10 ft is the length
:
Find the volume
10 * 5 * 4 = 200 cu/ft is the volume
Answer:
x = 4
