The triangle will be rotated with the rule of (x,y) → (-y,x). The image will be congruent to the pre-image, the side lengths will be the same and the angles too.
Answer:
The answer is C 8 2/5 im pretty sure.
Assume the following:
Brad has been in the soccer team for b years.
Scot has been in the soccer team for s years.
"The number of years that brad has been on the soccer team is 2 less than 5 times the number of years that Scott has"
means: b=5s-2
"in total,the boys have been on the soccer team for 10 years."
means: b+s=10
so we have the equations:
i) b=5s-2
ii) b+s=10
substitute b in ii) with 5s-2, as they are equal, from i
(5s-2)+s=10
5s-2+s=10
6s=12
s=2,
then , from b+s=10, b=8
Answer: Brad has been in the team for 8 years.
Solution:
<u>Note that:</u>
- Men:Woman = 3:2
- 54 women = Total woman in a company
<u>3:2 can also be written as 3x:2x.</u>
- => Men:54 = 3x:2x
- => 54 = 2x
- => x = 27
- => Men = 3x
- => Men = 3(27) = 81
- => Total employees: 81 + 54
- => Total employees: 135
There are 135 employees in total.
