Step-by-step explanation:

so the selling price is pretty much the cost price + the profit

so its

selling price = cost price + profit

Answer:B

Step-by-step explanation:because you need to add

Step-by-step explanation:

The Circumference is:

[tex]c = 2\pi \: r[/tex]

Radius r is:

[tex]r = \frac{d}{2} [/tex]

So,

[tex]c = \pi \: d \\ d = \frac{c}{\pi} \\ d = \frac{604}{\pi} \: cm[/tex]

Answer:

[tex]y = \frac{1}{100} \times 10{}^{x} [/tex]

Step-by-step explanation:

Use coordinates (2,1) and 3,10

The exponential equation is

[tex]y = a \times b {}^{x} [/tex]

Plug in the x and y values.xfor both functions of coordinates.

[tex]1 = a \times b {}^{2} [/tex]

[tex]10 = a \times b {}^{3} [/tex]

Divide the equation with the larger exponet by the other equation.

[tex]10 = b[/tex]

Substitute that in for one of the equations.

[tex]10 = a \times 10 {}^{3} [/tex]

Solve for a.

[tex]10 = a \times 1000[/tex]

[tex] \frac{1}{100} = a[/tex]

So our exponetial equation is

[tex]y = \frac{1}{100} \times 10 {}^{x} [/tex]

979.68

Step-by-step explanation:

Answer $17.22 was spent on a pass and $8.94 on lunch for each student and that implies a total of $26.16 was spent on each student

Step-by-step explanation:

Answer:

f(6) = -22, and g(-3) = 49

Step-by-step explanation:

f(x) = -4x + 2

f(6) = -4(6) + 2

f(6) = -24 + 2

f(6) = -22

I assume the 3 in g(x) = -2x3 -5 is cubed

g(-3) = -2(-3)^3 - 5

g(-3) = -2(-27) - 5

g(-3) = 54 - 5

g(-3) = 49

Answer:

Correct: A, B, C, E, AND F

Step-by-step explanation:

The reason being, that the larger the negative number, the smaller it gets. Think of it like this:

One person owes another, 8 dollars, and let's say he currently has none. So if he owes 8 dollars and he has none, then it would be 0-8, or, -8.

Now let's say someone else owes 200 dollars, and they have 100 dollars.

If they give 100 dollars, they still need to give another 100, right? so it would be -100 dollars, therefore, a greater debt than the guy with the 8 dollars.

If a negative number looks larger than another, in reality, it's just a bigger debt to pay, so it's smaller worth. -8 is larger than -100 because it's closer to 0.

Last example:

-100, -75, -50, -30, -23, -8, -2, 0, 1, 2, 3... See? -8 is closer to zero than -100, so it's larger.  

C is correct because negatives are smaller than positives. -1 is below 0, so it's smaller than 1, which is greater than 0.

Hope this helps :)

Answer:

D. 225

Step-by-step explanation:

Answer:

5:3

Step-by-step explanation:

step one: reduce the fraction

(since 5/3 is a reduced as it can get we can 'skip' this step)

step two: rewrite as a ratio

5/3  

=5 : 3

good luck :)

i hope this helps

Answer:

The first choice

Step-by-step explanation:

Answer:

88.86

Step-by-step explanation:

Okay, first find the area of the circle (πr^2)

The diameter of the circle is 14, however we need the radius. Simply divide the diameter by two.

[tex]\pi 7^{2}[/tex]

3.14*49 =153.86

Next, we find the area of the rectangle (bh)

13*5 =65

Subtract the rectangle from the circle.

153.86-65 =88.86

Hope this helps you :)

Answer: 15.45133224

Step-by-step explanation:

Find the area of the half circle.

r=6

pi (6)^2/2

Divide by two because it is a half circle not a circle.

pi (6)^2/2=18 Pi

We know there are two square with even side lengths so we know the sides of the two squares are 6 it is the same as the radius of the circle.

We multiply B*H= Area of the square

6*6=36 is the length of half of the rectangle aka the square

So we multiply that by 2 because there are 2 squares so we get 72

72-18 Pi= 15.45133224

Answer:

15.48 is the answer

Step-by-step explanation:

6×6×3.14=113.04

113.04÷2= 56.52

6×12= 72

72-56.52= 15.48

Answer:

16

Step-by-step explanation:

Divide 65 by 40 and then multiply it by 10. That gets you 16.25 so you have to round it because you can't have 1/4 of a person. So you'll get 16.

Answer:

7.5

Step-by-step explanation:

you think about the way you would normally solve it but a bit backwards therefore multiply 36x29 and that equals 1,044 and divide that from 7,830 and thats 7.5 multiply to check

Answer:

[tex]A=24[/tex]

Step-by-step explanation:

For finding the area of a trapezoid you first have to use the correct formula which is  [tex]A=\frac{1}{2}(b_1+b_2)h[/tex].

Now we plug in what we already know.

[tex]A=\frac{1}{2}(b_1+b_2)h\\A=\frac{1}{2}(5+7)(4)[/tex]

Now we start with the parenthesis

[tex]A=\frac{1}{2}(12)(4)[/tex]

Now if you can, you can multiply the 1/2 and the 12 and the 4 using a calculator or mentally

[tex]A=24[/tex]

24
