~ALGEBRA! PLEASE HELP!~Austin is climbing on a ladder that is attached against the side of a jungle gym wall. He is 5 feet off the ground and 3 feet horizontally from the base of the ladder, which is 15 feet from the wall. How high up the wall is the top of the ladder?
~Please show work :)

Answers

so I get it now!

so he is currently 5 feet vertically form the wall
he is currently 3 feet horizonatlly from the wall
the ladder's base is 15 total feet from the wall

height:base=5:3

to find the total height
x:15
multiply 5:3 by 5
25:15

so the top of the ladders's vertical height is 25 feet

so the answer is the ladder is 25 feet from the ground

A car is moving at a constant acceleration of 7.0 m/s/s. How fast (velocity) is it going after 4.0 seconds, if it starts from rest.? Show work using ESA format.

Answers

28 m/s is the velocity , when it is going after 4.0 seconds.

What is Acceleration?

When a point or an object moving in a straight line , the acceleration is the rate at which velocity changes with time, in terms of both speed and direction.

Here, given that,

A car is moving at a constant acceleration of 7.0 m/s/s

Now, we have,

Velocity = acceleration * time

After 4 sec. = 7*4 = 28 m/s

Hence, 28 m/s is the velocity , when it is going after 4.0 seconds.

A chef has some broccoli, cauliflower, carrots, and squash to make a vegetarian dish. List the possible combinations if he uses only 3 vegetables in the dish.

Answers

1. broccoli, cauliflower and carrots
2. squash, carrots and cauliflower
3. cauliflower, carrots and squash
I'm not going to type all the combination. So basically you have to multiply the vegetables by the number 3. So 3 x 4 is 12. Therefore he could do it in 12 different ways. Hope this helped.

You mix the letters S, E, M, I, T, R, O, P, I, C, A, and L thoroughly. Without looking, you draw one letter. Find the probability that you select a vowel. Write your answer as a fraction in simplest form my answer is B check my work plz

Answers

Easy, the answer is 5/12
Here, Favorable Outcomes(Vowels): E, I,O, I,A = 5
Total Outcomes: S, E, M, I, T, R, O, P, I, C, A, L = 12

So, Probability = Favorable Outcomes / Total Outcomes
P = 5 / 12

In short, Your Answer would be 5/12

Hope this helps!

Nina completed a third of her homework problems. But one-half of all the problems she solved had incorrect answers. If 7 of the problems she solved had correct answers, then how many problems are in her homework?

Answers

so what you would do is you do it backwards, 7x2 which is one half of her problems do that I'd solved and you get 14. now you times that by 3 and you get the final answer 14x3

7 * 2 = 14
