Answer:

$13,800

Step-by-step explanation:

She sells the car for 115% of the value of the car, because she wants a 15% profit. 115% of 12000 is the same as 12000*1.15, since 115% is eqaul to 1.15. 12000*1.15 = 13800

Answer:

The value of y is 125 when x=25.

Step-by-step explanation:

It is given that y varies directly as x. It means y is proportional to x.

Where k is constant of proportionality.

It is given that y=25 when x=5. Put x=5 and y=25 in the above equation to find the value of k.

Divide both sides by 5.

The value of k is 5.

The relation between x and y is defined by the equation

Put x=25 in the above equation.

Therefore the value of y is 125 when x=25.

Answer:

Yes because there is an 82.6% chance of a student chosen at random having one or more siblings.

Step-by-step explanation:

There are a total of 23 students of which 19 have 1 or more siblings. This means there's a 82.6% (19 is what percentage of 23) chance that a student chosen at random will have one or more siblings. Since this percentage is significantly high we can say it's likely that a student chosen at random will have 1 or more siblings.

Answer:

1) 5/3

2) 20/3

3) 20/6 = 10/3

4) 42/42 =1

Step-by-step explanation:

Since the formula for the area of a rectangle is a=lw (area= length times width), you just need to multiply the numbers.

If you are multiplying two fractions, you multiply the numerators(the numbers on top) and the denominators(the numbers on the bottom).

Ex. [tex]\frac{1}{2}* \frac{4}{7} = \frac{1*4}{2*7} = \frac{4}{14}[/tex]

If it is a fraction and a whole number, do the same thing, except you should write the whole number as the number over 1.  

Ex. [tex]5*\frac{1}{2}= \frac{5}{1}*\frac{1}{2}[/tex]

I hope this helps :)

Answer:

Half of a number is 15

Step-by-step explanation:

First of all, add commas between each option so it's easier to read I had a hard time figuring out what the options were because of this.

An equation is a statement that the values of two mathematical expressions are equal. An expression is a collection of symbols that jointly express a quantity. This means there has to be an equal sign when the phrases are put into numerical form.

Twice as much as a number:              2X

12 less than a number:                        X - 12

Half of a number is 15:                        X/2 = 15

The difference of 20 and a number: 20 - X

As you can see, only one of these phrases is an equation by definition, and that is X/2 = 15, or half of a number is 15. That's because it's the only one that values two expressions as equal.

Answer:

Given:

a=5

b=7

c=?

(a)^2+(b)^2=(c)^2

(5)^2+(7)^2=(c)^2

25+49=(c)^2

74=(c)^2

c=/74

c=8.60

Step-by-step explanation:

use the pythagorean theorem

inverse of square is square root

Answer:

Step-by-step explanation:

Question 1 is  2.

Question 2. 3 3/5 + 3 3/5 = 6 6/5 which equals 7 1/5 if you add another one.

so the answer for question 2 is " 1.521.

Answer:

Hello! answer: 17

Step-by-step explanation:

Assuming this is the Pythagorean theorem our formula would be

a^2 + b^2 = c^2

meaning both of those sides multiplied by themselves added together will equal a number which is the result of c multiplied byitself sorry it sounds confused but...

15 × 15 = 225 8 × 8 = 64 225 + 64 = 289

the square root or the (number multiplied byitself that equals 289) is 17 because

17 × 17 = 289 so × = 17 I hope that helps!

Answer:

x = 17 cm

Step-by-step explanation:

Since it is a right triangle and you are trying to find x, you can use the pythagorean theorem.  (a² + b² = c²)

First, plug the values into the equation:  (a and b represent the legs and c represents the hypothenuse; otherwise known as the longest side.)  

8² + 15² = c²

Square 8 and 15( or multiply them by themselves):

64 + 225 = c²

Add:  

289 = c²

Take the square root of both sides:  

√289 = √c²

Simplify:

17 = c

Therefore, x = 17 cm.  

Hope this was helpful!  Have a nice day!  :)

Answer:

the slope is 1/2 and the y-int is -3

Step-by-step explanation:

the slope is before the x and the y intercept is the b in y=mx+b

It's literally so obvious...

In a y = mx + b equation, m is the slope and b ins the y-intercept

So for this equation, we see that m is replaced by [tex]\frac{1}{2}[/tex], which is the slope, and b is replaced by -3, which is the y-intercept.

Answer:

$53.85

Step-by-step explanation:

[tex]\frac{y}{44.33} :\frac{15}{100}[/tex]

y · 100 = 44.33 · 15

100y = 664.95

100y ÷ 100 = 664.95 ÷ 100

y = 6.6495

$6.64 for a tip.

[tex]\frac{y}{44.33} :\frac{6.5}{100}[/tex]

y · 100 = 44.33 · 6.5

100y = 288.145

100y ÷ 100 = 288.145 ÷ 100

y = 2.88145

$2.88 for tax.

$2.88 + $6.64 + $44.33

$53.85

Answer: X=8

Step-by-step explanation:

60                            96

5                                 x

5*96/60=8

Answer:

8

Step-by-step explanation:

Write a proportion :)

Choose 96 and x and 60 and 5, for example.

[tex]\frac{60}{5} = \frac{96}{x}[/tex]

your equation will be 60(x)=96x5

60x=480

divide and you get 8!

Answer:

the submarine moves 17.5 feet every minute

Step-by-step explanation:

2100 / 120(minutes) = 17.5(minute)

and maybe you could divide 17.5m by 60 to get how many feet it moves every second, so

17.5m / 60 = 0.2916666

the submarine moves 0.2916666 feet below the surface every second

but this is coming from a 7th grader sooo

tell me if this isn’t right and I’ll try again!

Answer:

10 sections

Step-by-step explanation:

Perform the following division to answer this question:

   2 1/2 ft

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

1/4 ft/section

Convert 2 1/2 into an improper fraction with denominator 4:

 2 1/2 ft                  5/2 ft               10/4 ft

-------------------- = -------------------- = --------------------

 1/4 ft/section     1/4 ft/section      1/4 ft/section

This reduces to:

 10 ft

---------------- = 10 sections

1 ft/section
