Step-by-step explanation:
20% (100) + 15% (93) + 45% (86) + 20% (81)
= 20 + 13.95 + 38.7 + 16.2
= 88.85
Her course average is 88.85% (or 89%, rounded to the nearest integer).
First, subtract 10h from 15h so the variables are on the same side. You get:
5h+30<-45
Then, you can solve the inequality like any other equation. Subtract 30 from -45:
5h<-75
Finally, divide -75 by 5 to get your answer:
h<-15
Answer:
Step-by-step explanation:
A quadratic function has the formula ax² + bx + c
- To determine if a graph will be narrow or wide, the leading coefficient, a, will be the factor that determines this
- The greater the coefficient, the narrower the parabola
- The lesser the coefficient, the wider the parabola
Here all of the functions are in the form ax²
- In
, our "a" term is 
- In y = -2x², our "a" term is -2
- In y = -3x², our "a" term is -3
- In
, our "a" term is 
We can eliminate the two functions with the negative coefficients because they are much smaller than the two functions with the fractions as coefficients, and will therefore open much wider.
We can now compare the two remaining functions, and 
- Giving the two fractions common denominators would turn them into
and 
- The equation with the larger fraction will be the parabola that is the narrowest. In this case, it is the .
- Therefore, will have the narrowest graph

Step-by-step explanation:
Angles that add up to 90 are Complementary angles.
Two angles that have a common vertex and a common side but do not overlap are Adjacent angles.
Angles that are opposite each other and have the same measurment are vertical angles.
Angles that add up to 180 are Supplementary angles.
Hope this helps!! :D
Answer:
105 yards
Step-by-step explanation:
The other side is Width = 374/17 = 22.
So, the new width is 44 ( and the length is 17/2).
Perimeter = 2(17/2) + 2(44) = 17+88=105 yds.
So, 105 yards.
Mark me as Brainliest if this is correct! I really appreciate it! :D
