A general contractor is constructing a building that requires a concrete foundation that is to be 20 feet by 22 feet and 24 inch
ad-work [718]

Answer:

$38427

Step-by-step explanation:

Surface Area Formula: A=2(wl+hl+hw) where l=length w=width h=height

A=2((20(22))+(22(2))+(20(2)) = 1048ft^2

3 ft = 1yds -> 1048 ft = 349 1/3 yds

349 1/3(110)= 38426.66666

Create an equation to represent the total amount of money Matt and Phil earned at the fundraiser based on the number of cookies
bazaltina [42]

Answer:

A = (0.25)(0.8)(x + 1.25x)  

Step-by-step explanation:

Let x = number of cookies Matt made

Let 1.25x = number of cookies Phil made  {Phil made 25% more cookies than Matt}

A = total money earned

A = (0.25)(0.8)(x + 1.25x)  

They sold 80% of the combined cookies made at $0.25 each.

How do you simplify x-2/2-x?
Anestetic [448]

Answer:

-1

Step-by-step explanation:

Simplify the following:

x - 2/2 - x

Hint: | Reduce (-2)/2 to lowest terms. Start by finding the GCD of -2 and 2.

The gcd of -2 and 2 is 2, so (-2)/2 = (2 (-1))/(2×1) = 2/2×-1 = -1:

x + -1 - x

Hint: | Group like terms in x - 1 - x.

Grouping like terms, x - 1 - x = (x - x) - 1:

(x - x) - 1

Hint: | Look for the difference of two identical terms.

x - x = 0:

Answer:  -1
