At 0 hours: 24 boxes
After 1 hour: 24/2 = 12 boxes
After 2 hours: 12/2 = 6 boxes
After 3 hours: 6/2 = 3 boxes
She will have 3 boxes after 3 hours.
Hope this helps :)
7 - 2 (3 - 8x)
7 - 6 + 16x
1 + 16x
Nothing further can be simplified.
Answer:
B. 10.9
Step-by-step explanation:
Area of triangle= 1/2*24*h
∠N=90° ⇒ Area of triangle= 1/2*MN*ON
MN²= h²+(24-7)²
ON²= h²+7²
- 24h=MN*ON
- 24h= √h²+(24-7)²*√h²+7²
- (24h)²=(h²+17²)(h²+7²)
- 576k=k²+289k+49k+289*49
- k²-238k+14161=0
Answer:
The length would be 32 and the width would be 10
Step-by-step explanation:
For the purpose of this, we'll set the width as x. We can then define the length as x + 22 since we know it is 22 ft longer than the width. Now we can use those along with the perimeter formula to solve for the width.
P = 2l + 2w
84 = 2(x + 22) + 2(x)
84 = 2x + 44 + 2x
84 = 4x + 44
40 = 4x
10 = x
Now since we know that the width is 10ft, we can add 22ft to it to get the length, which would be 32ft.
