What is the surface area of the square pyramid below?A square pyramid. The square base has side lengths of 6 centimeters. The triangular sides have a height of 10 centimeters.
120 cm2
132 cm2
156 cm2
276 cm2

Answers

Since the squarebase has side 6 cm and triangular side has height 10 cm, the total surface area of square pyramid is 156 cm²

What is the Total surface area of a square pyramid?

A square pyramid has a square base and four triangular sides, its surface area, A = area of square base + 4 × Area of triangular side.

Area of square base

Area of square with side, L is A = L²

Area of triangularbase

Area of triangle with height and base, L which is the length of the square base is A' = 1/2Lh

Thus, total surface area of square pyramid ,

A" = L² + 4 × 1/2Lh

= L² + 2Lh

Given that the length of the square base is 6 cm and the height of the triangular side is 10 cm.

Now substituting the values of the variables intot he equation, we have

A" = L² + 2Lh

A" = (6 cm)² + 2 × 6 cm × 10 cm

A" = 36 cm² + 120 cm²

A" = 156 cm²

So, the total surface area of square pyramid is 156 cm²

sales tax and purchase price: suppose the sales tax rate in a certain state is is 8% how much sales tax is charged on a new car if the purchase price is $11,900?

Answers

To calculate the sales tax of an $11,900 purchase, we simply multiply the purchase prices by the sales tax rate.

8% is 8 parts of 100, which can be shown as a fraction with 8/100 or as a decimal with .08

Let's use the decimal in this case:

Sales Tax = purchase price x sales tax rate
Sales tax = 11,900 x .08
Sales tax = $952

So if the car was purchased at $11,900 in a state with an 8% sales tax rate, the sales tax would be $952 bringing the total cost of the car up to $12,852.

Models sells right handed and left Handed baseball gloves in one month 12 gloves for a total revenue 528. Right gloves cost 48 and left handed cost 36 how many right handed gloves were sold.

Answers

Answer:

8 Right handed gloves and 4 left handed gloves.

Step-by-step explanation:

Assumed the number of right handed gloves sold was x and the number of left handed gloves sold was y.

Given that 12 gloves were sold:

x + y = 12

x = 12 - y

Given that the total revenue made was 528:

48x + 36y = 528

Substitute x = 12 - y into 48x + 36y = 528:

48(12 - y) + 36y = 528

576 - 48y + 36y = 528

-12y = -48

y = 4

Substitute y = 4 into x = 12 - y:

x = 12 - 4 = 8

8 Right handed gloves and 4 left handed gloves.

11 were sold. You do revenue 528 divided by cost of that glove (48) equals 11.
