Answer: 40 pages in total
Step-by-step explanation:
Ms. Vega has read 20% of the book and this translates to 8 pages of the book.
20% = 8 pages
Assume the total number of pages is x:
20% * x = 8
0.2x = 8
x = 8 / 0.2
x = 40 pages in total
Answer:0
Step-by-step explanation:
Because it says rate of change witch don’t have one
Answer: 522.15 I think
Step-by-step explanation:
1. We assume, that the number 177 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 177 is 100%, so we can write it down as 177=100%.
4. We know, that x is 295% of the output value, so we can write it down as x=295%.
5. Now we have two simple equations:
1) 177=100%
2) x=295%
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:
177/x=100%/295%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 295% of 177
177/x=100/295
(177/x)*x=(100/295)*x - we multiply both sides of the equation by x
177=0.33898305084746*x - we divide both sides of the equation by (0.33898305084746) to get x
177/0.33898305084746=x
522.15=x
x=522.15
now we have:
295% of 177=522.15
Answer:
there are 20 girls in the band
Step-by-step explanation:
let number of boys= x
let number of girls = 10+x
so
x+10+x=30
2x=30-10
2x=20
x=20/2
x=10....
so if x= 10 then number of boys=10
number of girls=10+10=20....
Answer:
We find 3/4-5/24 = 0.54166666666 and try 2/7 x 6/8 = 0.21428571428
this is 0.069 too much we look at this as a fraction = 0.07 which is 1/10 approx of the 6/8. we then reapply 7/9 x 2/7 x 3/3 = 0.2
So we went up by 1 and can show another
2/7 x 7/10 = 2.0
So to 1dp there is lots of fractions including 2/7 x 7/9 = 2.0
But for three fractions that multiply together we can chose 5/7 x 2/6 x 6/6 = 2.0 As 5 x 2 x 6 = 60 and 60/360-102 = 60/258 = 0.20 and divided 198 =numbers 8 and 1/3 work with = 1.98/8.3 = 2.38554
We try again 1.68/8.3 = -0.2024 = 2/8 x 8/10 = 0.2
The balance is 1.3/2 x 0.8/2 = 0.65 x 0.333 = 13/20 x 1/3
3/5 x 1/3 = 0.2
