Answer: total sales $1260

Step-by-step explanation:

GIVEN

Base salary: $360

Additional salary: 1/6 of total sale

Total salary: $570

-------------------------------------------------------

Let x= the total sales

360+(1/6)x=570

Subtract 360 on both sides

(1/6)x=210

Divide 1/6 on both sides

x=210 ÷ (1/6)

Turn division of fraction into multiplying its reciprocal

x=210 × 6

Simplify

x=1260

Answer:

A = –3

B = 7

Step-by-step explanation:

Please see attached photo for explanation.

This is the square root of 6 over 3. The 3 is not inside the square root.

========================================================

Explanation:

sqrt = square root

We have sqrt(6) in the denominator. Your teacher wants you to rationalize the denominator, which means to take out the square root and instead have an integer here.

To achieve this, we multiply top and bottom of the fraction by sqrt(6) like so

[tex]\frac{2}{\sqrt{6}}\\\\\frac{2*\sqrt{6}}{\sqrt{6}*\sqrt{6}}\\\\\frac{2\sqrt{6}}{\sqrt{6*6}}\\\\\frac{2\sqrt{6}}{\sqrt{36}}\\\\\frac{2\sqrt{6}}{6}\\\\\frac{2\sqrt{6}}{2*3}\\\\\frac{\sqrt{6}}{3}\\\\[/tex]

Therefore,

[tex]\frac{2}{\sqrt{6}}=\frac{\sqrt{6}}{3}\\\\[/tex]

Answer:

The answer is 11n.

Step-by-step explanation:

This is because 6n and 5n have the common term of n and you can add them up as if it were just 6 + 5.

6n + 5n = 11n

Answer:

11n

Step-by-step explanation:

We are given the expression:

6n+5n

and asked to simplify.

To simplify, we must combine like terms. Let's analyze the terms.

6n ⇒ has a variable "n"

5n ⇒ also has a variable "n"

The like terms in this expression are the terms with a variable, n.

To combine like terms, add the coefficients and leave an n on the end.

(6+5)n

11n

The expression 6n+5n simplified is 11n.

Answer: The price increase = $2,860.

The price of the next model will be $57,860.

Step-by-step explanation:

Given: The next model sports car will cost 5.2% more than the current model.

Current model costs $55,000.

Price increase = 5.2%  of (Cost of current model)

= (0.052) x ($55000)

= $ 2860

So, the price increase = $2860.

Price of the next model = Cost of current model +  price increase

= $(55000+2860)

= $ 57,860

Hence, the price of the next model will be $57,860.

Answer: [tex]7\dfrac{7}{24}\text{ pounds}[/tex]

Step-by-step explanation:

Given, Monica gained weight in first week = [tex]\dfrac{5}{6}[/tex] pounds

She gained weight in second week = [tex]\dfrac34[/tex] pounds

She gained weight in third week = [tex]\dfrac34[/tex] pounds

She gained weight in fourth week = [tex]\dfrac34[/tex] pounds

She lost weight in fifth week = [tex]\dfrac38[/tex] pounds

Now, net weight she gained= [tex]\dfrac{5}{6}+\dfrac34+\dfrac34+\dfrac34-\dfrac{3}{8}[/tex]

[tex]=\dfrac{20+18+18+18-9}{24}\\\\=\dfrac{65}{24}\\\\=2\dfrac{17}{65}\text{ pounds}[/tex]

She need to gain [tex]10-\dfrac{65}{24}=\dfrac{240-65}{24}=7\dfrac{7}{24}\text{ pounds}[/tex]

Hence, she still have to gain [tex]7\dfrac{7}{24}\text{ pounds}[/tex]more.

Answer:

-5f + 6

Step-by-step explanation:

combining like terms

-4f - f = -5f

-9 + 15 = 6

Absolute value means the distance the number zero.

(3x+2) is (3x+2) from 0.

So right now, 3x+2>9, you have to get rid of the 2 on the left side (because you don't want the variable and the constant on the same side) .

Subtract 2 from the left side and 2 from the right.

Now it is 3x > 9-2

9-2=7

3x > 7

Answer:

y=-1.25x-4.25

Step-by-step explanation:

I had the same assignment.

The equation of the line that passes through (0,-b) and (c,0) is

7y - 8x = 28

The formula for calculating the equation of a line in point-slope form is expressed as:

[tex]y-y_0=m(x-x_0)[/tex]

m is the slope of the line

(x0, y0) is any point on the line

Given the coordinate points (0, -b) and (c, 0)

Since b  = -4 and c = -3.5

The required coordinate  points will be (0, 4) and (-3.5, 0)

Substitute the given parameters into the given formula for calculating the slope:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{0-4}{-3.5-0} \\m = \frac{4}{3.5}\\m = 8/7[/tex]

Substitute m = 8/7 and the point (0, 4) into the expression [tex]y-y_0=m(x-x_0)[/tex]

[tex]y-4=\frac{8}{7} (x-0)\\7(y-4)=8x\\7y-28=8x\\7y-8x=28[/tex]

Hence the equation of the line that passes through (0,-b) and (c,0) is

7y - 8x = 28

Answer:

a. 800 grams = 1.76 pounds

b. 700 grams = 1.54 pounds

Step-by-step explanation:

Here is a weight conversion problem.

In this question, we shall be making conversions from grams to pounds.

Kindly note that 453.592 grams = 1 pound as stated in the question

a. 800 grams

Kindly recall;

453.592 grams = 1 pound

800 grams = x pound

Thus;

453.592 * x = 800 * 1

x = 800/453.592

x = 1.764 pounds which is 1.76 pounds to 2 decimal places

b. 700 grams

1 pound = 453.592 grams

y pound = 700 grams

y * 453.592 = 700 * 1

y = 700/453.592

y = 1.543 pounds which is 1.54 to 2 decimal places

Step-by-step explanation:

Answer:

A. The equation of the line parallel to line L is y = – x

B. The equation of the line perpendicular to line L is y = x

Step-by-step explanation:

We'll begin by calculating the slope of line L.

This can be obtained as follow:

y = –x + 2

Comparing the above equation with:

y = mx + c

We can see that the slope (m) = –1.

Therefore, the slope of line L is –1

A. Determination of the equation of the line parallel to line L. This is illustrated below:

When two lines are parallel, their slope (m) is equal i.e

m1 = m2

m1 = – 1

– 1 = m2

This means that the slope of the line parallel to line L is –1

Now we shall determine the equation of the line parallel to line L as follow:

Coordinate = (0, 0)

x1 coordinate = 0

y1 coordinate = 0

Slope (m) = –1

y – y1 = m(x – x1)

y – 0 = –1 (x – 0)

y = – x

Therefore, the equation of the line parallel to line L is y = – x

B. Determination of the equation of the line perpendicular to line L. This is illustrated below:

When two lines are perpendicular, the product of their slope (m) is –1 i.e

m1 • m2 = – 1

but m1 = –1

–1 x m2 = – 1

Divide both side by – 1

m2 = –1/–1

m2 = 1

Now, we shall determine the equation of the line perpendicular to line L as follow:

Coordinate = (0, 0)

x1 coordinate = 0

y1 coordinate = 0

Slope (m) = 1

y – y1 = m(x – x1)

y – 0 = 1 (x – 0)

y = x

Therefore, the equation of the line perpendicular to line L is y = x

Answer: Hi!

So, to find the answer to this question, we would substitute the variables in the equation with the x, y coordinated of the solution.

x = 2 and 4 = y

Our equation now looks like this:

4 = 17(2) - 12

4 = 34 - 12

4 = 22

This is not a true statement! Therefore, the point (2,4) cannot be a solution for this equation.

  5.  Triangle UVT ~ ∆RSQ by SSS

Step-by-step explanation:

The ratios of side lengths, shortest to longest are ...

  VT : TU : UV = 42 : 70 : 84 = 3 : 5 : 6

  SQ : QR : RS = 15 : 25 : 30 = 3 : 5 : 6

Side lengths are proportional, so ∆UVT ~ ∆RSQ.

__

The triangle names need to be chosen so the sides are in the same order. Here UV and RS correspond, as do VT and SQ. That eliminates all but one answer choice.

Answer:

324 minutes or 5.4 hours

Step-by-step explanation:

400/3 = 133.333

133.333/60 = 2.2222

It took him one minute to paint 2.2222 square feet

720/2.2222 = 324 minutes

324/60 = 5.4 hours

Answer:

It will take Andy 5 hours and 24 minutes to paint 720 sq. ft.

Step-by-step explanation:

Since he painted 400 sq. ft. in 3 hours, then do 400/3 to get 133.33... sq. ft per hour. Then, do 720 / 133.33... to get 5.40000000001 hours taken. The 5 represents 5 hours, and the .4 represents 24 minutes (because 60 x .4 = 24).

Overall, you get 5 hours and 24 minutes of time to pain 720 sq. ft.
