What is the total surface area of the right regular pyramid with a square base?

Answers

Answer:....C. 106ft2

The lateral surface and the total surface areas of the prism are 96 in² and 2304 in² respectively.

What is surface area?

The surface area of a solid object is a measure of the total area that the surface of the object occupies.

Here,

Given is prism, we need to find the lateral surface and the total surface areas,

Lateral surface area = (perimeter of base) × length

Perimeter of base = 3 × 4 = 12 in

length = 8 in

The lateral surface area = 12 × 8 = 96 in²

Total surface area = (perimeter of base) × length × 2(base area)

= 96 × 2(3×4)

= 96 × 24

= 2304 in²

Hence, the lateral surface and the total surface areas of the prism are 96 in² and 2304 in² respectively.

Cell Phone Plan A charges $25 per month plus $10 per gigabyte of data. Cell Phone Plan B charges $50 per month plus $5 per gigabyte of data. What number of gigabytes of data results in the same cost for one month?

Answers

Answer:

[tex]gb = 5.[/tex]

Step-by-step explanation:

[tex]plan \: A. : \\ 25(per \: month) \: + 10(per \: gb) \\plan \: B. : \\ 50(per \: month) \: + 5(per \: gb) \\for \: both \: plan \: to \: be \: equal \: based \: on \: gb : \\ 50 + 5gb = 25 + 10gb \\ 5gb = 25 \\ gb = 5.[/tex]

The number of the Gega bytes for the same cost will be 5 GB.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Cell Phone Plan A charges $25 per month plus $10 per gigabyte of data. Cell Phone Plan B charges $50 per month plus $5 per gigabyte of data.

The two equations can be written as,

Plan A, 10G + 25

Plan B, 5G + 50

Equate two equations for the same cost.

10G + 25 = 5G +50

10G - 5G = 50 - 25

5G = 25

G = 5 gb

Therefore, the number of the Gega bytes for the same cost will be 5 GB.

Jennifer’s bank account is modeled by the following equation where x equals the number of weeks and
f(x) equals the total balance.
f(x) = 12x + 45
william's bank account balances after weekly deposits are showing in the following table.
Jennifer claims that her bank account is growing at a greater rate of change than William’s bank account. Is Jennifer correct? Justify your reasoning.

Answers

Jennifer is incorrect, her bank account is growing at a rate of 12x, and Williams bank account is growing at 14x. Jennifer just started out with more money.
NO JENNIFER IS NOT CORRECT

Jennifer is correct her bank account is growing at a greater rate of change than William’s bank account. Because, initially Jennifer has $45 in her account and it grows every week.

Given that, Jennifer’s bank account is modeled by the equation f(x)=12x+45.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Substitute x=0, 1, 2, 3, 4, we get y=12x+45

Now,

When x=0, y=12(0)+45=45

When x=1, y=12(1)+45=57

When x=2, y=12(2)+45=69

When x=3, y=12(3)+45=81

When x=4, y=12(4)+45=103

Jennifer is correct her bank account is growing at a greater rate of change than William’s bank account. Because, initially Jennifer has $45 in her account and it grows every week.
