Answer: 0.36 or 36%
60%=60/100=0.6
60% is the same as saying 60/100 or 0.6
To solve for the probability of this problem, we have to, multiply the odds of the two separate events together
event1 is a customer that spends more than 75$. The odds of that happening are .6
event 2 is a customer that spends more than 75$. The odds of that happening are .6
probability=event1*event2
probability=.6*.6
probability=.36 or 36%
Factors of 24: 1,2,3,4,6,8,12,24
factors of 30: 1,2,3,5,6,10,15,30
factors of 42: 1,2,3,6,14,21,42
Step-by-step explanation:
let no. of hours be x.
45x - 12 ≥ 117
45x ≥ 129
x ≥ 2.8667 (5sf)
therefore, 3 hours (round up to next whole number).

Your answer is gram hope this helps that is what unit to use :)
Let's call the two numbers
and
.
Given these variables, we can say:
, based on the first sentence in the problem.
Also, remember that the reciprocal of a number is simply 1 divided by the number. Thus, we can say that:

To solve, we can simply substitute
in for
in the second equation and solve.


- Get terms on the left side to a common denominator for easier addition


- Cross multiplication (
)


- Subtract
from both sides of the equation

- Factor left side of the equation

Now, notice that we have found two solutions, but the problem is only asking for one. This <em>likely </em>means that one of our solutions is extraneous. Let's take a look. Remember that the smaller positive number is equal to 14 less than the larger number. However,
,
Since
is not positive in this case,
is not a solution.
Thus,
is our only solution. In this case,
,
which means that the smaller number is 14 and the larger number is 28.
