Answer:
Mariana has better performance.
Step-by-step explanation:
We are given that in a training session, Mariana made 12 of the 15 shots on goal that she kicked and Carla had an effectiveness of 75%.
And we have to find which girl's performance is better.
Since it is stated that Carla had an effectiveness of 75%.
Similarly, we will find the effectiveness of Mariana;
Total shots available to Mariana = 15 shots
Number of shots on goal = 12
So, her effectiveness = 
= 
= 80%
This shows that Mariana has a better performance as compared to Carla as 80% > 75%.
Answer:
b = 32
Step-by-step explanation:
If we are talking a² + b² = c² instead of looking for the hypotenuse we look for a leg and it doesnt matter where it is placed.. so for there forth you'll do
24² + b² = 40²
and then from there you square all the numbers so then you get
576 + b² = 1600
then subtract 576 from both sides so you are left with
b² = 1024
and finally square root it
b = 32
Answer:
3x + 12
Step-by-step explanation:
5x + 6(x - 2) - 8(x - 3) ← distribute parenthesis
= 5x + 6x - 12 - 8x + 24 ← collect like terms
==(5x + 6x - 8x) + (- 12 + 24)
= 3x + 12
Answer:
b^2
step-by-step explanation:
The slant height is the hypotenuse of a right triangle with sides length 7 m and 19 m. Use the Pythagorean theorem.
h² = (7)² + (19)²
h² = 49 + 361
h² = 410
h = √(410)
h = 20.25
rounded to nearest whole number would be 20 m
