Answer=A
To find the gcf, we need to factor each number.
154=2*7*11
196=2*2*7*7
The number have a factor of 2 and a factor of 7 in common, so...
GCF=2*7
Answer:
There are 25 students in the class.
Step-by-step explanation:
Let x be the number of students in the class
12% failed and the number of students is 3
x*12% = 3
x*.12 = 3
Divide each side by .12
x * .12 /.12 = 3/.12
x =25
There are 25 students in the class
Answer:
1 to 2, 2 to 4, 3 to 6
Step-by-step explanation:
4s double is 8, 5s double is 10, so whichever you choose just double it.
In mathematically, 8/4 = 2, 10/5 = 2, so x to 2x
Step-by-step explanation:
In order to find the length of side TS, first we need to find the length of side TR which is perpendicular to side QS.
By Geometric mean property:

Answer:
- 17.9% of men have a HS degree
- 50.5% of 2-yr degree earners were women
- 27.9% of the group has a 4-yr degree or higher
Step-by-step explanation:
It is convenient to use a spreadsheet to total the numbers for you. This reduces errors and put the numbers in a form that makes it easy to see what you're working with in any given calculation.
men with HS degree = (male HS)/(all male)
= 76/425 ≈ 0.1788 ≈ 17.9%
__
2-yr degrees that are women = (female 2-yr)/(2-yr total)
= 248/491 ≈ 0.5051 ≈ 50.5%
__
4-yr degrees in group = (4-yr degrees)/(total group)
= 258/925 ≈ 0.2789 ≈ 27.9%

<em>Comment on the problem</em>
The spreadsheet is identical to the one used for your other problem. All that needed to be done was to enter the new numbers. The formatting, headers, and formulas remained the same. For solving these problems, it's a matter of picking the two numbers needed from the appropriate row or column and computing their ratio.
(The computations were done by hand here to better show you the numbers used and the rounding to tenth percent. They can be done in the spreadsheet with point and click.)
