Zero pairs are generated by combining the EQUAL number of positive and negative numbers .
A zero pair could be -11 + 11
The pints of paint that Mike needs to buy in order to paint 4 boxes is 9 pints.
How many pints is needed?
The first step is determine the total surface area of a box.
Total surface area of a cuboid = 2 (lw + wh + lh)
where:
l = length
w = width
h = height
2 x[ (5 x 9/2) + (9/2 x 7/2) + (5 x 7/2) ]
2 x ( 45/2 + 63/4 + 35/2) = 111.5ft
The second step is to determine the total surface area of 4 boxes:
111.5 x 4 = 446
Now, divide 446 by 50
446 / 50 = 9 pints
Answer:
n - (-4) ≥ 10
4(n+5) ≥ 48
Step-by-step explanation:
n - (-4) ≥ 10
n + 4 ≥ 10
n ≥ 6
4(n+5) ≥ 48
4n + 20 ≥ 48
4n ≥ 28
n ≥ 7
Step-by-step explanation:
= -1 × 729
= -729
