1. We assume, that the number 25000 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 25000, so we can write it down as 100%=25000.
4. We know, that x% equals 3700 of the output value, so we can write it down as x%=3700.
5. Now we have two simple equations:
1) 100%=25000
2) x%=3700
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=25000/3700
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 3700 is what percent of 25000
100%/x%=25000/3700
(100/x)*x=(25000/3700)*x - we multiply both sides of the equation by x
100=6.75675675676*x - we divide both sides of the equation by (6.75675675676) to get x
100/6.75675675676=x
14.8=x
x=14.8
now we have:
3700 is 14.8% of 25000
Answer:
The mean of the combined group is 76.67 ≈ 77
Step-by-step explanation:
- The sum of the grades in Tom's group is 20×70 = 1400
- The sum of grades in Alice's group is 10×90=900
- The sum of gradees in the combined group is =1400+900=2300
- Then the mean grade of the combined group is
where
- 2300 is the sum of the all grades in the combined group
- 30 is the total number of people in the group
Answer:
the first one
Step-by-step explanation:
Answer:
The length of the circular arc is 8.64 inches
Step-by-step explanation:
Length of circular arc (L) = central angle/360° × 2πr
central angle = pie/4 = 45°, r (radius) = 11 inches
L = 45°/360° × 2 × 3.142 × 11 = 8.64 inches (to two decimal places)
Answer:
0.06*
Step-by-step explanation:
*Assuming you mean 6%
6 percent can be written as 6/100, or six hundredths.
In decimal form, six hundredths is .006.
