Let the side of each side of photo is a inch.

So area of photo = (side)^2 = a^2

But as given area of photo is 9 square inch.

So a^2 = 9

a =  \sqrt{9}
          = 3

So side of photo is 3 inch.

What is the length of the base of a right triangle with an area of 24m and a height of 4m
insens350 [35]
To find the length of the base, we have to understand that area of triangle:

Base x height/2

Therefore we would multiply the area by 2 and divide by 4 to find the answer:

24x2/4

=48/4

=12

Therefore the answer is 12m.

you are serving bratwurst and hamburgers at your annual picnic. you want at least three bratwurst and hamburgers for each of you
Varvara68 [4.7K]
B for Brats and H for Hamburgers
3 total for each of 30 guests
B + H = 3x30 = 90
Then $1.25B + $0.75H <= to $120
Solving for B=90-H
1.25B + 0.75(90-B) <=120 yields cost of B is $52.50 so B = 42.
90-42 = 48 H
So you can buy 42 Brats and 48 Hamburgers
