Answer:

The lengths of the sides of the square base are $2\sqrt{2}\ units$

Step-by-step explanation:

<u><em>The correct question is</em></u>

A triangular prism has an isosceles right triangular base with a hypotenuse of square root of 32 and a prism height of 12. a square prism has a height of 12 and its volume is equal to that of the <em><u>triangular</u></em> prism. what are the dimensions of the square base, in simplest radical form?

we know that

The volume of a prism is given by the formula

$V=Bh$

where

B is the area of the base

h is the height of the prism

so

If the volumes of the solids are the same and their heights are the same, then the area of the base of the triangular prism must be equal to the area of the base of the square prism

step 1

Find the area of the base of the triangular prism

Remember that in a right isosceles triangle, the two legs are equal

Let

x ---> the length side of each leg

Applying the Pythagorean Theorem

$(\sqrt{32})^2 =2x^2$

$x^2=32/2\\x^2=16\\x=4\ units$

The area of the triangular base is equal to

$A=\frac{1}{2}(4)(4)=8\ units^2$

step 2

Find the dimensions of base of the square prism

Let

b ---> the length side of the square base

The area of a square is given by the formula

$A=b^2$

we have

$A=8\ unit^2$ ----> is the same that the area of triangle

substitute

$8=b^2$

$b=2\sqrt{2}\ units$

therefore

The lengths of the sides of the square base are $2\sqrt{2}\ units$

When using the order of operations to simplify (7 + 3) * 4 - 1 + (6 + 8), which operation should be performed first?

enot [183]

Answer:

addition because it's in parentheses and following PEMDAS parentheses comes first so you do addition first.

I hope you find this helpful :D

A grocery store sells Swiss cheese for $5.90 a pound. To the nearest cent, what is the cost per ounce of Swiss cheese? Round you

Debora [2.8K]

Answer:

37 cents

Step-by-step explanation:

Given that a grocery store sells Swiss cheese

Rate per pound = 5.90 dollars

1 pound =16 oz,

Hence cost of 16 ounces is given as 5.90

SO cost of one ounce of Swiss cheese = $\frac{5/90}{16} =0.36875$

Or 36.875 cents

Round off to nearest cent as

37 cents since after decimal digit 8 is more than 5.

Hence answer is 37 cents
