17. Subtraction. According to the order of operations, he should've done the exponent of 3 first.
18. He then did 15×2. According to the order of operations, he should've done the multiplication of 8×2, since, if there are only multiplication and/or division left, you work left to right. He isn't correct.
19. 16, I think, I did it in my head.
Answer:
the fraction of quart of milk does each of the four friend get is 1 ÷ 24
Step-by-step explanation:
The computation of the fraction of quart of milk does each of the four friend get is shown below:
= Sharing quart of milk × fraction of friends
= 1 ÷ 6 × 1 ÷ 4
= 1 ÷ 24
Hence, the fraction of quart of milk does each of the four friend get is 1 ÷ 24
Answer:
It should be the second answer!
Step-by-step explanation:
Answer: Choice B) 3/5
==================================================
Explanation:
The smaller horizontal side is JM = 15
The larger horizontal side is NQ = 25
The ratio of these corresponding sides is:
small/large = 15/25 = (5*3)/(5*5) = 3/5
----------------
Alternatively,
The smaller vertical side is ML = 18
The larger vertical side is QP = 30
The ratio of these corresponding sides is:
small/large = 18/30 = (6*3)/(6*5) = 3/5
----------------
Either way, the answer is 3/5
Step-by-step explanation:
Let width be x
according to question
length = 2x-4
perimeter = 58
now,
perimeter = 2(length + width)
58 = 2(x+2x-4)
58 = 6x-8
6x = 66
x = 11
putting value of x in length
2x-4
= 2 X 11 -5
= 18
hence the dimensions of the rectangle is 18 and 11
