Answer:
c 0.28 m
Step-by-step explanation:
A construction worker uses a tape measure to find that a pipe is 28/100 of a meter long. Select the decimal that represents the same length.
a 1.28 m
b 2.8 m
c 0.28 m
d 0.028 m
Given:
Length of the pipe in fraction = 28/100
What is the equivalent length in decimal?
28/100
How many hundred can you get in 28
= 0. Remainder 28
Add 0 to 28 which makes it 280
How many hundred can you get in 280
= 2 remainder 80
Add 0 to 80 which makes it 800
How many hundred can you get in 800
= 8 remainder 0
Bring all the quotient together
Therefore,
28/100 m = 0.28 m
Time taken to fill the pool by faucet:
A-2 days
B-3 days
C-4 days
D-6 hours=6/24=1/4 days
Thus the time taken for the 4 faucets working together to fill the pool will be the GCD of the time taken by the 4, which will be:
GCD(2,3,4,0.25)
=1
=1 day
Answer: 1 day or 24 hours
1/8 of a pizza = $2.50
1/8 of a pizza, multiplied by 8
= 8/8 (or 1 whole)
8/8 = $2.50, multiplied by 8
1 pizza = $20.00
Answer:
336
Step-by-step explanation:
A square has four equal sides therefore you know the perimeter is 20+20+20+20 = 80. Since the square and the rectangle have the same perimeter the perimeter of the rectangle is also 80. We already know that two of the sides are 28 cm long so we can subtract those two sides from 80. That gives us 24 which is the sum of the two remaining sides. Each of these sides is 24/2 which is equivalent to 12. The formula for area of a rectangle is length times width. Your length is equal to 28 and your width is equal to 12. When you multiply these you get 336 which is your final answer.
