What is the height of a triangle, if the area is 20 square inches and the base is 5 inches? Be sure that you can explain how you found your answer.

Answers

Answer 1

so normally we would be finding the area of a triangle which is a=h*b/2

but in this case we are finding the height so theirs 3 ways to do this but i prefer the basic way

20=1/2(5)h

20=2.5

8=h

and to find out if that was correct lets do  8*5=40      40/ 2 =20  so this is correct

the height is 8

Answer 2

Answer:8

All the teachers at a school are either left footed or right footed.
At the school
the number of left footed teachers:the number of right footed teachers = 3:13
At the school, there are 18 left footed teachers.
How many right footed teachers are there?

Answers

Answer:

78

Step-by-step explanation:

Ratio of left-footed teachers to right-footed teachers = 3:13

18 left-footed teachers; 3x6 = 18 (3:13 is a simplified ratio and to get 18, you have to multiply 3 by 6)

13x6 = 78 (whatever you do to one side, you have to do the other)

78 right-footed teachers

The are 78 teachers are right footed.

What is Algebra?

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

The ratio of the number of left footed teachers: the number of right footed teachers = 3:13

Total left footed teachers = 18

let the Common ratio be x.

Then , number of left footed teachers= 3x

and, number of right footed teachers= 13x

So, 3x= 18

x= 6

Hence, there are 78 teachers are right footed.

Dean is comparing prices on ground beef. Store A is selling 5 pounds of ground beef for $23.49. Store B is selling 8 pounds of ground beef for $36.96. Which store is offering the better deal on ground beef? Show work

Answers

Answer:

Store B

Step-by-step explanation:

First you need to set up an equation for each store

Store A  (you have 5 pounds of something sold at $x per pound. which together totals $23.49)

[tex]5x=$23.49[/tex]

Store B (you have 8 pounds of something sold at $x per pound. which together totals $36.96)

[tex]8x=36.96[/tex]

Then you want to isolate the x for each equation to find the price per pound. You do this by diving each total cost, by how many pounds that you get.

Store A: $23.49/5 pounds= $4.698

Store B: $36.96/ 8 pounds = $4.62

This gives you a price per pound, so B is the correct answer because B is $0.07 cheaper per pound, giving you the better deal.
