Answer:

200 Bricks

Step-by-step explanation:

1/3 of the bricks were not used(which was 50 bricks), meaning that 3/3 is 150 bricks of the pile. Since 150 is 3/4 of the original pile, that means that there was 200 bricks at the beginning.

Pythagorean Theorem a=11 b=60 c=?
zhuklara [117]

Answer:

61

Step-by-step explanation:

The Pythagorean Theorem is a fundamental in geometry that involves looking at two sides of a right triangle and finding out the length of it. Let's use the formula with the corresponding numbers.

The formula for this question would be c=\sqrt{a^2 + b^2}

Since we know that a = 11 and b = 60, we can do the following and substitute :

c = \sqrt{11^2 + 60^2}

11 squared is 121

60 squared is 3600

Now we need to add the two number together :

121 + 3600

3721

Since this number is under the square root, we have to square root it. :

\sqrt{3721}

61

Therefore c is equal to 61.

Answer:

C) 120 square feet

Step-by-step explanation:

Note that the bed is in the shape of a <em>triangle</em>. You are also finding the area of the bed (Use the formula Area = 1/2(base * height)).

The base = 20, height = 12. Plug in the corresponding numbers to the corresponding variable.

A = 1/2(20)(12)

Simplify.

A = 1/2(20)(12)

A = (20 * 12)/2

A = (10 * 12)

A = 120

C) 120 square feet is your answer.

~

*Good luck!

 50+ 7.99 x =y
50+ 7.99 (40)= y
50+319.60= y
369.60=y

50+ 7.99 x =y
50 + 7.99 (50)
50+ 399.50=449.50
6.99(30)=209.70
449.50 + 209.70 =659.2
