Answer:The height of the roof in his house is 72.43 ft.

Step-by-step explanation:

The volume of square pyramid is :

B= area of the base.

h= the height.

Given that,

The roof is a square pyramid in shape. The volume of the roof is 18929.333 cubic feet.

The side length of the base of the roof is 28 feet.

Since the base of the roof is square in shape.

The area of the square is = side²

The area of the base is =(28×28) square feet

=784 square feet

Assume the height of the roof be h ft.

Then, the volume of the roof is =

square feet.

According to the problem,

ft.

The height of the roof in his roof is 72.43 ft.

A bakery has fixed costs for retail space, electricity, and appliances of $15,000. The variable cost of baking a cookie is 0.25

den301095 [7]

Answer:

Step-by-step explanation:

That $15,000 sounds like an annual amount, not a monthly or weekly amount. In the absence of clarification of this, I will include that $15,000 in the following calculations:

Let the # of cookies baked be z and the number of cakes be k.

Then:

Total cost = $15,000 + ($0.25/cookie)z + ($3.53/cake)k

In this specific case, where the number of cookies is z and the number of cakes is k, the formula

Total cost = $15,000 + ($0.25/cookie)z + ($3.53/cake)k

becomes ...

Total cost (z, k) = $15,000 + ($0.25/cookie)(400) + ($3.53/cake)(200),

and this works out to:

TC (z, k) = $15,000 + $100 + $706 = $15,000 + $806 = $15,806.

No cakes or cookies could be good enough to warrant production costs that high!

Double-check to ensure that you have copied this problem down completely and accurately.

anastassius [24]

Given

An algebraic expression is the difference between seven times a number and three times that number.

To find:

The algebraic expression.

Solution:

Let x be the unknown number.

Multiplication is used for times and subtraction is used for difference.

7 times of a number = 7x

3 times of that number = 3x

The difference between seven times a number and three times that number is

$Difference = 7x-3x$

$Difference =4x$

Therefore, the algebraic expression for the given statement is 7x-3x and its simplified form is 4x.
