Step-by-step explanation:

Multiplying powers with same base

Answer:

32 yards (squared)

Step-by-step explanation:

Length x width = area (LxW=A)

Step 1:

Length = 6 yards

Width = 5 1/3 yards

Step 2:

Multiply 6 x 5 1/3 because 6 is the length, 5 1/3 is the width, and LxW=A.

6 x 5 1/3 = 32 yards (squared)

Answer:the two numbers are 2 and 19

Step-by-step explanation:

Let one of the numbers be x

and the second be   7+ 6x

so that the sum of the two numbers which totals 21 be expressed as  

x + (7+ 6x) = 21

x+ 7+6x= 21

7 + 7x = 21

7x= 14

x= 14/7 = 2

one of the numbers = 2

the other number given as

7+ 6x = 7+ 6 x 2= 7+12= 19

The numbers are 2 and 19 .

The numbers as described in the question are; 2 and 19

From the given problem statements;

The first number = y

The second number = x

Hence, y = (7 + 6x)

Their sum is therefore;

Hence, the second number is; 7 + 6x = 7 + 6(2);

Step-by-step explanation:

6 is greater than 5 so it rounds up

Answer:

Step-by-step explanation:

Since you are reflecting about the x axis you keep the x coordinate the same and multiply the y coordinate by -1 so you have point (8,-4)

Answer:

y = 6x

Step-by-step explanation:

You can easily find the slope by using slope formula:

(y2-y1) / (x2-x1) (the numbers are subscript)

E.g: (24-12) / (4-2) = 12/2 = 6

m(slope) = 6

Hope this helped :)

Answer:

4448.23

Step-by-step explanation:

[tex]AV=PV(1+\frac{i}{n})^{nt}\\\\6000=PV(1+\frac{.06}{12})^{5*12}\\\\6000=PV*1.3488\\\\PV= 4448.23[/tex]

The present value of an investment that will be worth $6000 at the end of five years is, $4448.23

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Annual value = $6,000

Time = 5 years

Rate = 6%

Hence, We get;

A = P (1 + r/n)ⁿˣ

Substitute all the values, we get;

⇒ 6000 = P (1 + 0.6/12)⁶⁰

⇒ 6000 = P × 1.3488

⇒ P = $4448.23

Thus, The present value of an investment that will be worth $6000 at the end of five years is, $4448.23

Answer:

10,080cm for the whole thing.

the lateral part of the triangular prism is 1680cm

Step-by-step explanation:

30 x 25 = 750cm

30 x 24 = 720cm

30 x 7 =  +210cm

              1680cm

25 x 24 =    600cm

600 x 7 = +4200cm

                  4800cm

4200cm x 2 = 8400cm (both of the triangles)

  1680cm

+8400cm

10,080cm

Answer: D , p = n (800 - 450) - 3000

Step-by-step explanation: Firstly, you have to account for how much money Rafael is making off of each computer (800 - 450). That factor is then multiplied by the variable "n" which represents the amount of computers sold. Lastly, since this is an equation to calculate his monthly profits, you have to subtract the rent that he is paying ($3000) from the total profit that he made off of selling the computers. Therefore, giving you the equation

P (profit) = n (amount of computers sold) (800-450) - 3000 (rent).

The equation that represents Rafael's monthly profit selling 'n' numbers of computers is D. P = n(800 - 450) - 3000.

An equation represents equality for the terms that are on the both side of the equal sign.

Given Rafael buys computers for 450 dollars and sells them for 800 dollars each.

He also had to pay 3000 dollars for rent and utilities for the store and the number of computers sold in each month is given by 'n'.

∴ The equation that represents his profit(P) in a month is,

P = n(800 - 450) - 3000.
