C 37%
F) None of the above

Answers

9514 1404 393

Answer:

B) 3.2%

Step-by-step explanation:

The future value is given by ...

A = P(1 +r)^t

Filling in the given information, we can solve for r.

4097.01 = 3500(1 +r)^5

4097.01/3500 = (1 +r)^5 . . . . divide by 3500

(4097.01/3500)^(1/5) = 1 +r . . . . take the 5th root

(4087.01/3500)^(1/5) -1 = r ≈ 0.032 = 3.2%

The annual interest rate on this account is 3.2%.

the length of a rectangle is five inches less than three times its width . if the perimeter of the rectangle is 150 inches , find the dimensions.

Answers

Step-by-step explanation:

let x be the width of the rectangle.

given

length =

[tex]3x - 5[/tex]

inches.

also given Length + Width = 150 inches,

[tex]3x - 5 + x = 150 \\ 4x - 5 = 150 \\ 4x = 150 + 5 \\ 4x = 155 \\ x = 155 \div 4 \\ = 38.75in[/tex]

Since

Length = 3x-5 in

Width = x in,

Length = 3(38.75) - 5 = 111.25 in

Width = 38.75 in

How do you know if a number is rational irrational or not real number

Answers

Answer:

A rational number can expressed as a whole number, integer, square root, fraction, and more as long as it's not imaginary. However, the number has to be clean like 1/2=0.5, 1/3=0.333, -1, 200. If it is a number that goes on forever and is not repeated like 1.22222, then it's an irrational number like pie-3.14159..., 5/0, 2.201845. If you have an imaginary number- 6i, then this would be considered as non real numbers like x+2, red, wind, and y/7.

WILL GIVE BRAINLIEST TO FIRST CORRECT ANSWER

Answers

Answer:

x = 1/2 y = -1/3

Step-by-step explanation:

Split it into 2 equations:

10x-9y=8

and

21y+15x=0.5

10x - 9y = 8

Step 1: Divide both sides by 10:

x = (8+9y)/(10)

Substitute x = (8+9y)/(10) into 21y+15x=0.5 :

21y + (3(8+9))/(2) = 0.5

Solve for y

y= -1/3

Substitute y= -1/3 into x = (8+9y)/(10)

x = 1/2

A coated heavy- gauge plastie pipeline can be installed, with pumps spaced appropriately along the pipeline. Alternatively, canal can be built; however, it will have greater water loss than the pipeline, due to evaporation and poaching along the canal route. To compensate for the water loss, the canal will have a greater carrying capacity than the pipeline. It is estimated it will cost $125 million to install the pipeline. Major replacements are planned every 15 years at the cost of $10 million. Pumping and other annual operating and maintenance costs are estimated to be $5 million. The canal will cost $200 million to construct; its annual operating and maintenance costs are anticipated to be S1 million. Major upgrades of the canal are anticipated every 10 years, at the cost of $5 million.
