A flying squirrel lives in a nest that is 12 feet up in a tree, but wants to
eat an acorn that is on the ground 9 feet away from the base of his tree.
If the flying squirrel glides from his nest to the acorn, then scurries back
to the base of the tree, and then climbs back up the tree to his nest,
how far will the flying squirrel travel in total?

Answers

It’s the Pythagorean theorem which is a squared+b squared =c squared it works with right triangles to find missing sides. You have a=12 and b=9, so 12^2 is 144 and 9^2 is 81. 81+144=225. The square root of 225 is 15 and that’s your answer

is there a difference between a prisoner and a student when it comes to freedom

Answers

Answer:

For my opinion, it is a yes

Explanation:

there is a difference since most students may experience stress when in terms in acads but if we realized something that when we grow older, we have our limits from the ones in childhood.

Students can play and do whatever they want. they aren't limited with the places and the capacity they have as a child

but for prisoners, it will be harsh mostly when it comes to money since being a prisoner will cost much to the government to let you free.

That is only FOR MY OPINION. I'm sorry if it isn't accurate.

Answer:

Yes for me

Step-by-step explanation:

Cause prisoner will be free years or month, student is different to prisoner cause prisoner will not do homework, activities, and never experience outdoor. It depend how you feel or act so goodluck and be safe✨

Pls help it’s due tomorrow!

Answers

Answer:

x=4 and y=−2

Step-by-step explanation:

1. 3(−7x−8y=−12)

−4(4x−6y=28)

2. −21x−24y=−36

−16x+24y=−112

3. divide

4. Substitute 4 for x in−7x−8y=−12:

(−7)(4)−8y=−12

5. −8y−28+28=−12+28

divide 8 to 16

y=-2

Answer:

(4, -2)

Step-by-step explanation:

Given system:

-7x - 8y = -12 4х - 6у = 28

Simplify the second equation:

2x - 3y = 14

Solve the system by elimination, multiply the first equation by 2 and the second equation by 7 and add up. Solve for y:

-7x(2) - 8y(2) + 2x(7) - 3y(7) = -12(2) + 14(7)-16y - 21y = -24 + 98-37y = 74y = -74/37y = -2

Find x using the second equation:

2x - 3(-2) = 142x = 14 - 62x = 8x = 4

Solution is (4, -2)
