Answer:

21.25

Step-by-step explanation:

you would multiply 25 by 0.15 to get the percent being taken off then subtract that from your original price

Answer:

J. All real numbers

A number is :

[tex]x[/tex]

_________________________________

Three quarters of it means :

[tex] \frac{3}{4}x \\ [/tex]

_________________________________

Decrease by 20 means :

[tex] \frac{3}{4}x - 20 \\ [/tex]

_________________________________

Equals to 82 means :

[tex] \frac{3}{4}x - 20 = 82 \\ [/tex]

_________________________________

What is that number ?

x asked so we must solve the above equation for x.

Let's do it....

[tex] \frac{3}{4}x - 20 = 82 \\ [/tex]

Plus sides 20

[tex] \frac{3}{4}x = 82 + 20 \\ [/tex]

[tex] \frac{3}{4}x = 102 \\ [/tex]

Multiply sides by 4

[tex]3x = 102 \times 4[/tex]

Divided sides by 3

[tex]x = \frac{102 \times 4}{3} \\ [/tex]

[tex]x = \frac{102}{3} \times 4 \\ [/tex]

Simplify

[tex]x = 34 \times 4[/tex]

[tex]x = 136[/tex]

So that number is 136 .

Answer:

First, two lines are perpendicular if one has slope m, and the other has slope -1/m (Not 1m as Alan says)

That is the first error of Alan.

Now, there is another error.

If m = 0, then -1/m tends to minus infinity (in this case we would have a vertical line).

But we can not really divide by zero, so we should state that:

m can not be zero, if a line is horizontal, the perpendicular line must be vertical.

Step-by-step explanation:

Let say the unknown number we dont know is x

2x+4=6

2x=6-4

2x=2

x=2/2

x=1

So the unknown number is 1

Answer: 594 and 30888

Step-by-step explanation:

5400 x 0.11 = 594

594 dollars in commission of one week

52 weeks in a year

52 x 594 = 30888 dollars made in 2011

594 dollars in commission of one week.

$30888 he make in commission in​ 2011.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Stocks sold= $5400

Commission each week = 11%

So, Commission on Stocks sold

= 5400 x 0.11

= 594

Thus, 594 dollars in commission of one week.

As, 1 Year = 52 weeks

So, He can make in 2011 = 52 x 594 = $30888

Answer:

i think it's

x is greater than or equal to -8

Step-by-step explanation:

Answer:

-2.9375

Step-by-step explanation:

2x-14x+47=0

16x+47=0

16x=-47

x=-2.9375

Answer:

x=7+√ 2 or x=7-√ 2

Step-by-step explanation:

x^2-14x+47=0

Completing the square,

x^2-14x+49-2=0

x^2-14x+49=2

x^2-7x-7x+49=2

x(x-7)-7(x-7)=2

(x-7)^2=2

x-7=√ 2 or x-7=-√ 2

x=7+√ 2 or x=7-√ 2

Answer:

a. 8m

b. 7cm

Step-by-step explanation:

a. Area of a square is s², where s is the side length.

To find s:

s² = 64

s = √64

s = ±8

length cannot be negative, hence it is positive 8

b. Perimeter of a square is 4s = P, where P is the perimeter and s is the side length.

4s = 28

s = 7

Answer: 6.89 per pound (assuming you meant which is the better deal)

Step-by-step explanation:

There are 16 ounces in a pound so you can multiply, 3.5 x 2 (since it is 3.5 for 8 ounces) to get 7. Therefore $6.89 for a pound is cheaper.

Answer:

c = √58

Step-by-step explanation:

Pythagorean Theorem: a² + b² = c²

Because we have a right triangle, we can use the Pythagorean Theorem to help us solve for missing side lengths:

7² + 3² = c²

49 + 9 = c²

58 = c²

c = √58

Answer: c = √58

Answer: 1/4

Step-by-step explanation:

(Not really sure how to explain it, but there's the answer.)

Given:

The cost y (in dollars) of renting a segway for x hours is

[tex]y=30x+25[/tex]

To find:

The initial fee and the cost per hour.

Solution:

We have,

[tex]y=30x+25[/tex]       ...(i)

The slope intercept form of a linear equation is

[tex]y=mx+b[/tex]      ...(ii)

where, m is slope is b is y-intercept or initial value.

From (i) and (ii), we get

[tex]m=30,b=25[/tex]

The value of m is 30, so the slope is 30. It means cost per hour is $30.

The value of b is 25, so y-intercept is 25. It means the initial fee is $25.
