Answer: 1/4, 4/7, 5/8
Step-by-step explanation: There are three ways:
1. <u>Convert each to a decimal: </u>
1/4 = 0.25
4/7 = 0.571
5/8 = 0.625
2. <u>Convert to a common denominator:</u>
It looks like we can multiply each by a whole number that will result in a denominator of 56:
1/4 *(14/14) = 14/56
4/7*(7/7) = 35/56
5/8 *(8/8) = 32/56
Now they can be directly compared to get the answer.
3. <u>Estimate the values. </u>
5/8 is clearly larger than 1/4. 4/7 is somewhere in between. Therefore, 1/4, 4/7, 5/8
Answer:
available is 111.5cm tall and Olivia is 88.5cm
Step-by-step explanation:
ok so Olivia is half the height of Luca which means the height of Luca divided by 2
177÷2=88.5
so Olivia is 88.5cm tall
we know that Available is 23cm taller than Olivia which means
the height Available= the height of Olivia+ 23cm
=88.5+23
=111.5
so Available is 111.5cm tall
i'm guessing this is asking what percentage it went up by? if so it went up by 190.47 percent. ***400,000 / 210,000 = 1.9047619***
Answer: With 11 pipes, you need 31.82 minutes to fill the tank.
Step-by-step explanation:
Let's define R as the rate at which one single pipe can fill a tank.
We know that 7 of them can fill a tank in 50 minutes, then we have the equation:
7*R*50min = 1 tank
Whit this equation, we can find the value of R:
R = 1 tank/(7*50min) = (1/350) tank/min.
Now that we know the value of R, we can do the same calculation but now with 11 pipes.
Then the time needed to fill the tank, T, is such that:
11*(1/350 tank/min)*T = 1 tank
We need to isolate T.
T = 1 tank/(11*(1/350 tank/min)) = 31.82 min
With 11 pipes, you need 31.82 minutes to fill the tank.
