Answer:

n = 52m/6.5

Step-by-step explanation:

We are given that;

Distance run; d = 6.5 miles

Time;t = 52 minutes.

Thus, at rate per minute, is;

v = 6.5/52 miles/minutes

Now, we want to find number of minutes, n, she will take to

run m miles at this rate of 6.5/52.

Thus, m/n = 6.5/52

Cross multiply to give;

52m = 6.5n

n = 52m/6.5

If you roll a fair six-sided die and a fair four-sided die, what is the probability that neither die shows a 1?
Masja [62]
For the first die, 5 out of 6 are not 1. 
That is 5/6. 
For the second die, 3 out of 4 are not 1. 
That is 3/4.  
Multiply 5/6 by 3/4 to get the probability.
5/6 x 3/4 = 20/72 
Simplify once to get 10/36. 
Do it again to get 5/18. 
In decimal form it is 0.2777 and in percent form it is 27.77%. 
Hope this helps!

A food service in the mall prepares free samples of chicken to give out during dinner time. One hour later, the food service has
jeka94

The food service gave out 80 samples, which is 4 fewer than 70% of the total number of samples they prepared. Lets make x the total number of samples they prepared.

So lets write it as an equation

80 = (70% of x) -4

70% converts to a decimal by moving the decimal point 2 spaces up, so it is 0.7

80 = 0.7x-4

Add 4 to both sides of the equation

84 = 0.7x

Divide both sides by 0.7 to isolate the x

x = 120

The food service prepared 120 samples.
