Step-by-step explanation:

Given that:

Daily wages paid to a saleswoman = $80

Wages paid for each sale made by her = $6

Target of today's earnings = more than $150

To find:

Least number of sales to be made so that the total earnings today is more than $150.

Solution:

Number of sales for today = [tex]x[/tex]

Wages for one sale = $6

Wages for [tex]x[/tex] number of sales = $6[tex]x[/tex]

Total earnings = Per day sales + Wages for [tex]x[/tex] number of sales > $150

[tex]80 + 6x > 150[/tex]

we need to solve for above inequality to find the least number of sales to be made to meet the goal.

Subtracting 80 from both sides:

[tex]\Rightarrow 6x>70\\[/tex]

Dividing both sides by 6:

[tex]\Rightarrow x > 11[/tex]

Therefore, at least 12 sales must be made.

Step-by-step explanation:

Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10-9. So, how does this work?

We can think of 5.6 x 10-9 as the product of two numbers: 5.6 (the digit term) and 10-9 (the exponential term).

Here are some examples of scientific notation

Answer:

2/3 is the slope of the perpendicular line

Step-by-step explanation:

1) put into slope-intercept form (y=mx+b)

-8=2y+3x

-2y=3x+8

y=-3/2x-4

2) the line is perpendicular so the slope will be opposite and the reciprical of the original slope.

so, because the original was -3/2, the new one is 2/3

Answer:

198 yards

Step-by-step explanation:

Sean wants the sting of each balloon to be 9 feet, and he wants to get a total of 66 balloons.

The total length of stings required for 66 balloons would be;

total length of balloon strings = 66 x 9 feet

                                                 = 594 feet

But the string is sold by the yard at the store.

So that,

1 yard = 36 inches = 3 feet

x yard = 594 feet

Thus,

x = [tex]\frac{594}{3}[/tex]

  = 198 yards

x = 198 yards

Therefore, the total length of string that Sean would need is 198 yards.

Answer:

y=-2x-2

Step-by-step explanation:

y-4=-2(x+3)

Remove parentheses

y-4=-2x-6

Move your constant to the right

4=-2x-6+4

Calculate the sum

y= -2x-2

Answer:

x = 1

Step-by-step explanation:

3(x + 6) -5 = 16

You want to first add the 5 (*flipping the sign)  over to the 16

making your equation ...

3(x +6) = 21

Then you want to distribute the 3 to x and 6

making you equation

3x + 18 = 21

Then you want to subtract the 18 (*flipping the sign) to the right side

making the equation....

3x = 3

Lastly, divide the 3 on the left to the 3 on the right making the answer 1

x = 1

Gross income is money earned before taxes are taken from a paycheck

Step-by-step explanation:

Gross income is money earned before taxes are taken from a paycheck

Gross income refers to the total amount of money earned by an individual over a specific period of time usually a year before any deductions such as taxes is made.

Gross income includes income earned from all sources. It can also be called Gross pay on a paycheck.

For example, if an individual earns $100 in a year and is expected to pay a tax of 2%. The gross income is $100 before tax is deducted

Slope formula: y2-y1/x2-x1

Step-by-step explanation:

8-6/9-6= 2/0

Answer:

Step-by-step explanation:

Alright we need to prove that both the triangles are similar so lets get started

The slope formula is:

Slope = Change in y / Change in x

m = Δy / Δx

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

Where, m is the slope and [tex](x_1,y_1) , (x_2,y_2)\\[/tex] are any points on the line

In this graph we are given three points which are

(0 , 2) , ( 6 , 6) and (9 , 8)

So for our first triangle we use the 2 points (0 , 2) and (6 ,6) and calculate the slope,

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{6-2}{6-0}\\\\m=4/6\\\\m=2/3\\[/tex]

So the slope turns out to be 2/3 , Now for our second triangle use the 2 points (6 , 6) and (9 , 8)

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{8-6}{9-6}\\\\m=2/3\\[/tex]

So we can see the the slope's are equal that's the answer to your first part.

Second part

Yes they are similar due to the property of corresponding angles where angle x of the first triangle equals angle x for the second triangle and angle y for the first triangle equals angle y for the second triangle and both the triangles have 90° se they are similar because all three angles are similar. (AAA = angle angle angle property) I have attached a to make you understand it better.
