A fitness center charges a monthly fee to use the facilities plus $3 for each fitness class. One month Sara took 6 classes and paid $30 for the month. If she paid $48 for the next month how many classes did she take?

Answer:

-5=x

Step-by-step explanation:

2x-7=5x+8

get like terms on the same side

-7-8=5x-2x    (I did this in one step hope you understand if not i can explain)

simplify

-15=3x

divide both sides by 3

-5=x

Answer: Step E

Step-by-step explanation:

The error is in the last step. In Step D, we see that we're supposed to subtract the second part from the first part. We also see we have the terms 2x-8 in the numerator on the right. Since we're subtracting, the expression should actually be -2x +8. 3 -2x +8 should be -2x +11 which is not the numerator in Step E so the last step is wrong.

Answer:

A.) 1018 square inches

Step-by-step explanation:

The largest sphere will have a diameter equaling the length of the cube (see picture).

If the side length of the cube is 18 inches, the diameter of the sphere is also 18 inches. Use the surface area formula for a circle:

[tex]SA=4\pi r^2[/tex]

For this formula, we need the radius of the sphere. Divide the diameter by 2:

[tex]\frac{18}{2}=9[/tex]

The radius is 9 inches. Plug this into the equation:

[tex]SA=4\pi *9^2[/tex]

Simplify the equation:

[tex]SA=4\pi *81\\\\SA=324\pi \\\\SA=1017.87[/tex]

Round the result to the nearest whole number:

[tex]1017.87[/tex] → [tex]1018[/tex]

The surface area is 1,018 inches².

:Done

Picture:

In a 2D version, we can clearly see that if the circle fits snuggly inside of the square, the diameter of a sphere is the same as the length of a side of the cube.

Answer:

1. The solutions marked on the attached graph

2.The solutions are (-2, 0) and (6, 0)

3. The discriminant would be positive

Step-by-step explanation:

Based on the given graph

1.

Look at the attached figure to see the solutions

2.

∵ The graph intersects the x-axis at points (-2, 0), (6, 0)

∴ The solutions are (-2, 0) and (6, 0)

3.

∵ The discriminant is positive if the graph intersects the x-axis

   at 2 different points

∵ The given graph intersects the x-axis at points (-2, 0) and (6, 0)

→ They are different points

∴ The discriminant would be positive

Step-by-step explanation:

I'm uploading a picture because it thought it had innapropriate words for some reason.

The transformation of a shape includes rotating and reflecting the shape;

(a) Image of BC after [tex]120^o[/tex] rotation

First, we calculate the angle of rotation, to make the hexagon lie onto itself

[tex]\alpha = \frac{\theta}{n}[/tex]

Where:

[tex]\theta = 360^o[/tex] --- angle at the center of the hexagon and the circle

[tex]n = 6[/tex] -- sides of hexagon

So, we have:

[tex]\alpha = \frac{360^o}{6}[/tex]

[tex]\alpha = 60^o[/tex]

This means that a [tex]60^o[/tex] rotation would make the hexagon lie onto itself.

We have that:

[tex]120^o = 60^o \times 2[/tex]

This means that the shape can be rotated [tex]60^o[/tex]  twice to achieve the [tex]120^o[/tex] rotation.

The image of BC at the first [tex]60^o[/tex] rotation is AB

The image of BC at the next [tex]60^o[/tex] rotation is FA

Hence, the image of BC after [tex]120^o[/tex] is FA

(b) Image of BC after reflection over line FC

Line FC divides the hexagon into equal halves.

So, when reflected over line FC, each segment would be flipped on the opposite segment.

The opposite of segment BC is DC.

Hence, the image of BC reflecting over FC is DC.

Answer:

bananas=$12.72

grapes=$9.48

oranges=$5.85

apples=$5.36

Step-by-step explanation:

To find the total cost for each fruit you would multiply the number of fruit by the cost.

bananas=3*4.24=$12.72

grapes=4*2.37=$9.48

oranges=3*1.95=$5.85

Answer:

22.6

Step-by-step explanation:

The cos of any angle is its adjacent over its hypotenuse:

cos 37 = 17.3 / x

We can multiple both sides by x to get x * cos 37 = 17.3 and then we can divide both sides by cos 37 to get x by itself:

x = 17.3 / cos 37

So solving for x, x is equal to about 22.6
