Answer:
16)
Bobby - 70
Hannah - 90 (Wins the round)
Carlos - 80
17)
Bobby - 7 (Wins the round)
Hannah - 3
Carlos - 5
Step-by-step explanation:
First we can make the variable n into each of the values they chose for the equations. Let's start with 16.
The equation is - (3+7) X (10 - n ÷2)
Now let's input the numbers 6 , 2, and 4 one at a time to figure out the answer.
USE PEMDAS!!!

Hope this Helps!!! :)
Let me know if I should change anything or if the answer was perfect!!!
Answer:
The distance from point A to B that Haley needs for the pole to be perpendicular is:
Step-by-step explanation:
To solve this exercise, imagine that it is a triangle, where the height is the pole, which is 10 feet, and the base of the triangle is the distance between the base of the pole and the point located by Jalen and called C, which it would have a measurement of 6 feet, finally, the measurement between A (the point located six feet) and B (the highest part of the pole) would correspond to the hypotenuse of a triangle,
Therefore, having these two measures, you could use the Pythagorean theorem to find the hypotenuse of a triangle with those measures and solve it, remember that the Pythagorean theorem is:
- Hypotenuse^2 = opposite leg^2 + adjacent leg^2
We replace the values given in the exercise:
- Hypotenuse^2 = (10 ft)^2 + (6 ft)^2
- Hypotenuse^2 = 100 ft^2 + 36 ft^2
- =
- Hypotenuse =
- <u>Hypotenuse = 11.66 ft approximately</u>.
In this form, Jalen can be sure the pole is perpendicular to the ground when <u>the distance from point A to B is 11.66 ft approximately</u>.
If i'm not mistaken there is only 10 or 25 ways he could arrange them,
ie: 23,895, 28395, ect....
A.) m< E is 31 degrees and the m< F is 43 degrees
B.) m< B is 80 degrees and the m< C is 40 degrees
