Answer:

A=75

B=60

C=45

every triangle is equal to 180 so we divide

180/12=15

then we multiply each angle by 15

5*15

4*15

and 3*15

don't forget to check your work by adding the answers together to get 180

An open-topped glass aquarium with a square base is designed to hold 444 cubic feet of water. What is the minimum exterior surfa

In-s [12.5K]

Answer:

291.05ft²

Step-by-step explanation:

Volume of the aquarium = L³

L is the length of one side of the aquarium

444 = L³

L = cuberoot[444]

L= 7.63ft

Since the glass aquarium is opened at the top

Total surface Area = 5L²

Total surface Area = 5(7.63)²

Total surface Area = 291.05ft²

Hence the minimum exterior surface area of the aquarium is 291.05ft²

n + 11 and 11 + n

Step-by-step explanation:

Let n be the unknown number,

n is increased by 11,

That is, n + 11

By the commutative property of addition,

The expression would be,

11 + n

For drawing a model that shows n + 11

Take two boxes in which first shows n and second shows 11 and add them,

Similarly, for showing 11 + n, take first box that shows 11 and second box that shows n then add them.
