14) 51. You divide 100 by 60 and multiply the answer by 85%.
15) about 200 students loved music. You would round the 398 to 400 and the 52% to 50%, which is half.
16) They would cost the same because adding all of the discount together for the first computer would equal 30% which is the same amount as the second computer.
Hope this helped you!
If you would like to complete the factorization, you can do this using the following step:
9g^2 + 30g + 25 = (3g + 5) * (3g + 5) = (3g + 5)^2
The correct result would be 5.
Answer:
f−1(x)=x/2−7/2
Step-by-step explanation:
Answer:
30 degrees
Step-by-step explanation:
The things we do have and want to find are as follows:
- We know that this is a right triangle, and one angle is 90 degrees
- We want to find an angle
- Relative to that angle, we are given an adjacent side as well as the hypotenuse
One equation that encompasses this is cos(θ) = adjacent/hypotenuse, so
cos(m∠H) = 10√3 / 20
For an equation of form cos(x) = y, we can say that arccos(y) = x. Therefore, we can write our equation as
m∠H = arccos(10√3 / 20)
m∠H = 30 degrees
It should be congruent angles, for "congruent angles" are angles that have the same measures
vertical angles measurements are also equal, however, you want to be as broad as possible
hope this helps
