Find the area of the rectangle that has a perimeter of 8x − 14 units and a length of x − 5 units.

Answers

Answer 1

Answer: Area = 4 square units

Perimeter of the rectangle = 8x - 14 units

Length of the rectangle = x - 5 units

Let the width of the rectangle = x units

Perimeter = 2( length + width)

8x - 14 = 2(x - 5 + x)

Solve the parenthesis for once

8x - 14 = 2(x + x - 5)

8x - 14 = 2(2x - 5)

8x - 14 = 4x - 10

Collect the like terms

8x - 4x = -10 + 14

4x = 4

Divide both sides by 4

4x/4 = 4/4

x = 1

Since, the length is x - 5 units

Length = 1 - 5

Length = - 4units

Length = 4 units

Width = 1 unit

Area = length x width

Area = 4 x 1

Area = 4 square units

Express 55 miles per hour in kilometers per hour.km/hr(Round to the nearest whole number as needed.)

Answers

Okay, here we have this:

Considering the provided amount in miles per hour, we are going to convert it to kilometers per hour, so we obtain the following:

[tex]\begin{gathered} \frac{55mi}{h}\cdot\frac{1.6km}{1mi} \\ =\frac{55\cdot1.6km}{h} \\ =88\frac{\text{ mi}}{h} \end{gathered}[/tex]

Finally we obtain that 55 miles per hour are equivalent to 88 kilometers per hour.

Which term describes the slope of the line below?

A. Undefined
B. Zero
• C. Positive
D. Negative

Answers

Answer:

D. Negative

Step-by-step explanation:

The slope is negative because the line goes down from left to right. In other words, as x increases, y decreases.

A slope would be positive when the line goes up from left to right. In other words, as x increases, y increases.

A slope would be zero if the line is horizontal, so as x increases, y remains constant.

A slope would be undefined if the line is vertical. It is undefined because x remains constant while y changes. Lines are functions, which mean for every input there is exactly 1 output. If there are multiple y values for 1 x value, then this is not a function and therefore has an undefined slope.

How to find a sine relation when a cosine relation is given?

The sine relation is the ratio of the height to the hypotenuse. Meanwhile, the cosine relation is the ratio of the base to the hypotenuse.

The relation of sine and cosine is given as follows:

[tex]\sin \theta=\pm\sqrt{1-\cos^2\theta}[/tex]

It is given that cos θ = (2/5)

So, the sine value can be obtained from the given value.

[tex]\sin \theta=\pm\sqrt{1-\cos^2\theta}\\=\pm\sqrt{1-(2/5)^2}\\=\pm\sqrt{21}/5\\ =-0.92[/tex]

So, the sine value for the given cosine value is - [tex]\sqrt{21}/5[/tex] or -0.92.

Note that we omitted the positive value because it is given that the tangent value is negative, so the angle lies in the fourth quadrant, where the sine value is also negative.

The smallest whole numbers that makes the statement true are:

(a) 41 - 9 ≡ 2 (mod 5)

(b) 17 + 8 ≡ 4 (mod 7)

Let a, b and m be integers. Then a is said to be congruent to b modulo m if m divided a-b. That is,

a ≡ b(mod m) if and only if m divided a-b.

Also here, if b is the smallest integer satisfying this relation, then b is the remainder when a is divided by m.

(a) So for  41 - 9 ≡   (mod 5)

⇒ 32 ≡    (mod 5)

The smallest whole number satisfying this congruence is the remainder when 32 is divided by 5 which is 2.

That is,  41 - 9 ≡ 2 (mod 5)

(b) Similarly for 17 + 8 ≡   (mod 7)

⇒ 25 ≡   (mod 7)

The smallest whole number which makes this statement true is the remainder when 25 is divided by 7, which is 4.

What is the rate of return when 12 shares of Stock

commission on the sale is $9.
Rate of Return = profit or loss
total cost
First, calculate the total cost.
Hint: 12 shares were purchased for $22
each. So first, we'll multiply 12 - 22.
12- $22= $[?]

Answers

The rate of return of the 12 shares purchased by A is 72.72%.

Here, we are given that A purchases 12 shares at $22 per share.

So the cost price of 12 shares will be = 12 × 22

= 264

A sold these shares at $465.

The commission on sale = $9.

Thus, the total cost of the shares will be = 264 + 9

= $273

Hence, the total profit of A will be-

465 - 273

= 192

The rate of return is calculated as-

Rate of return = profit/cost price × 100

Thus, here-

Rate of return = 192/264 × 100

= 0.7272 × 100

= 72.72%

Thus, the rate of return on these 12 shares purchased by A is 72.72%.

Answers

The linear equation that passes through the point (-6, 5) and B is the point (-2,-3) is:

y = -2x - 7

How to find the linear equation?

A general linear equation is:

y = a*x + b

Where a is the slope and b is the y-intercept.

If the line passes through two points (x₁, y₁) and (x₂, y₂) then the slope is:

s = (y₂ - y₁)/(x₂ - x₁)

In this case, we have the points (-6, 5) and (-2,-3), then the slope is:

s = (-3 - 5)/(-2 + 6) = -8/4 = -2

Then we have:

y = -2*x + c

To find the value of the constant we use one of the points, I will use (-2, -3) to get:

Answers

If  the cost for using 35 HCF IS 61.83. . the cost for using 19 HCF of water is :$68.31.

How to find the cost price?

Straight line: y=mx+b, m=slope, b=y-intercept

Let y=cost of using 19 HCF water

Let x =amount of water used

m=∆y/∆x =(61.83 - 32.13) / (35-19)

m=∆y/∆x =29.7 /16

m=∆y/∆x = 1.85625

m=∆y/∆x = 1.86  ($/HCF) (approximately)

equation: y=1.86x+b

Solving for b using point (19, 32.13)

32.13 =1.86×19+b

32.13=35.34+b

b=35.34 -32.13

b=3.21

equation:

f(x)=1.86x+3.21

f(25)=1.86×35+ 3.21

1. 3x-18> 12 , add 18 on both sides:

3x - 18 + 18 > 12 + 18

3x > 30

2. Divide both sides by 3:

3x/3 > 30/3

x > 10

So, to be a part of the solution, x must be greater than 10, then the interval that represents the solution is (10, ∞). From the given options, the only one that is not included in this interval is 8, because it is less than 10, then the answer is 8.

You are offered two different sales jobs. The first company offers a straight commission of 6% of the sales. The second company offers a salary of $ 270 per week plus 2% of the sales. How much would you have to sell in a week in order for the straight commission offer to be at least as good?

Answers

One needs to sell $6750 worth of goods to make the straight commission be at least good to the secondary offer

Straight offer = 6% commission on the sales

Second offer = $270 + 2% of the sales

For the straight offer to be competitive with the second offer it should be able to cover the fixed income of $270

Let x be the sales made in the week

Formulating the equation we get the following:

6% of x = 270 + 2% of x

6/100x = 270 + 2/100x

4/100x = 270

x = 6750
