It takes three quarters of an hour to lie 24 carpet tiles.

1 answer:

8 0

Okay so three quarters of an hour is 45 minutes.
6 hours = 360 minutes.
360/45 = 8.
So the scale factor is 8.
Just do 24 x 8 and you get the answer (192 carpet tiles)
I think this is right ??

Answer:

3/20

Step-by-step explanation:

By question it's given that ,

$\implies \dfrac{a}{b}=\dfrac{2}{5}$

$\implies \dfrac{b}{c}=\dfrac{3}{8}$

And we need to find out the value of a/c .For that Multiply both of them , we have ;

$\implies \dfrac{a}{b} \times\dfrac{b}{c}=\dfrac{2}{5}\times \dfrac{3}{8} \\\\\implies \dfrac{a}{c}= \dfrac{3}{20}$

A book sold 39,300 copies in its first month of release. Suppose this represents 6.1% of the number of copies sold to date. How

alexdok [17]

Answer:

644,262 copies

Step-by-step explanation:

Since this is a proportion problem, and we are given three values and one variable which is the total number of copies sold to date (x). Then we can use the Rule of Three to solve this problem. To do this we simply multiply the diagonal values and divide by the last value which would give us the value of the variable x

39,300 copies <======> 6.1%

x copies <=======> 100%

(100*39,300) / 6.1 = 644,262 copies

Therefore, a total of 644,262 copies have been sold to date.

25m/s to miles/h Can anyone solve it? With explanation if you can

Dimas [21]

25 meters per second x 60 seconds = 1500 meters per minute

1500 meters per minute x 60 minutes per hour = 90,000 meters per hour

1 mile = 1609.34 meters

90000/1609.34 = 55.92 miles per hour

round answer to either 55.9 or 56 mph depending on what you need.
