Liam rode his bike to the store every day. It took him 45 minutes to get to school and 45 minutes to get home. If he rode for 3 weeks, how many minutes will he ride in all?
Answers
Answer:
1,890 minuts
Step-by-step explanation:
3 weeks = 7 days x 3 = 21 days
He rides his bike for "45 minutes to get to school and 45 minutes to get home" which is 90 minutes per day.
Therefore, in total, he rode for 21 days x 90 minutes per day = 1,890 minutes

Usingthe percent rule, It is found that 6 is 12.5 percent of 48.
How to find how much percent 'a' is of 'b'?
Suppose a number is 'a' Suppose another number is 'b' We want to know how much percent of 'b' is 'a'. Then, it is calculated as:
(in percentage)
We are asked to find that 6 is what percent of 48.
Let x is the unknown percent.
100% / x% = 48/6
Now multiply both sides of the equation by x
(100/x)x = (48/6)x
Then divide both sides of the equation by (8) to get x
100 = 8x
100/8 = x
12.5 = x
x=12.5
Hence, It is found that 6 is 12.5 percent of 48.

100%/x%=48/6
(100/x)*x=(48/6)*x - we multiply both sides of the equation by x
100=8*x - we divide both sides of the equation by (8) to get x
100/8=x
12.5=x
x=12.5

So that means two numbers multiplied to each other equal to x. We can just think of itwo numbers that when multiplied equal to x as a and b.
So that means the side lengths are a and b. And ab = x (will be using this right next).
And it was multiplied by some scale factor that made the new area 9x. So if the scale factor is y, then:
y can not equal to -3, because the length of a side of any polygon can never be negative.
So the dilation is 3.
And so if the dimension is 5 by 8.
Then the area is
And so then
And then after the dilation, it would be
We could check it another way too. Since we said the scale factor is 3, then:
So basically 15 by 24 is the new dimensions :)
