We can use a factorial for this:
4! = 4*3*2*1 = 24
There are 24 combinations of 4 numbers.
Answer:
3
Step-by-step explanation:
3 ÷ 3 = 1
21x ÷ 3 = 7x
There is no other common factor.
I'm assuming you mean to say that the clock already showed 10 seconds when she started the race.
It took her 5 seconds to run 100 meters since 15-10 = 5.
To find her speed, divide 100 over 5 to get 100/5 = 20 meters per second
20 meters per second is approximately equal to 44.7387258 miles per hour.
Something seems really off because the fastest record speed for a human runner was around 28 mph. Though of course, this is just a hypothetical math problem.
101/2 is 50 1/2
23/8 is 2 7/8
50 1/2 - 2 7/8 = 47 5/8
47 5/8 / 1 2/3 = 27.69, to the nearest hundredth
Since he can't make fractions of picture frame, the answer is 27
Answer:
26%
Step-by-step explanation:
percent change = (new number - old number)/(old number) * 100%
Here, the new number is £504, and the old number is £400.
percent change = (£504 - £400)/(£400) * 100% =
= £104/£400 * 100% = 0.26 * 100% = 26%
