Shelby owns a sporting goods store. She buys knowre tennis rackets at a
wholesale price of $100 per racket and sells them for $150. What is the
percent markup?

Answer:

-7/2

Step-by-step explanation:

Use two points.

(6, -21) and (12, -42)

slope = (y2 - y1)/(x2 - x1)

slope = (-42 - (-21))/(12 - 6)

slope = -21/6

slope = -7/2

Answer:

the answer is 32

Answer:

34 X 20.39 = 693.26

693.26 X 52 = 36049.52

100-29.51 = 70.49

36049.52/100 X 70.49 = 25411.306648

monetary value rounded 2dp = $25411.31

answer is D

Answer:

71

Step-by-step explanation:

Add 46 to each number, see if the sum is in the list. In the set of 7 numbers listed, two of them are even (24 and 38), and the other 5 numbers are odd

71

We do not need to look at all differences.

We need to find two numbers fairly far appart,

and not all look promising.

You could look at approximate differences,

or you could look at the last digit.

71-35 and 63-17 are the only promising differences,

because 71 and 63 are the only numbers large enough to be 46 more than another number in that list,

and when you calculate the last digit you calculate

11-5=6 and 13-7=6.

71-35=36

Answer:

The pre-image is the point you start with. To check the transformation rule, substitute the values of the coordinates (4, 5) into the rule. You get (4, 5) → (4+4, 5+7). Simplify to get (4, 5) → (8, 12). This is the image. Instead the rule was applied to the image. This is the source of the error.

Answer:

218 students purchased tickets at the dance.

Step-by-step explanation:

Let,

x be the number of presale tickets

y be the number of tickets sold at the dance

According to given statement;

x+y=334      Eqn 1

18x+24y=7320    Eqn 2

Multiplying Eqn 1 by 18

18(x+y=334)

18x+18y=6012      Eqn 3

Subtracting Eqn 3 from Eqn 2

(18x+24y)-(18x+18y)=7320-6012

18x+24y-18x-18y=1308

6y=1308

[tex]\frac{6y}{6}=\frac{1308}{6}\\y=218[/tex]

Therefore,

218 students purchased tickets at the dance.

11 : 22 : 132

Step-by-step explanation:

1 + 2 + 12 = 15

165 ÷ 15 = 11

1 × 11 = 11

2 × 11 = 22

12 × 11 = 132

11 : 22 : 132

I got answer 16.9

Step-by-step explanation:

1. Let's first look at triangle XYC. We know angle Y is 90 degrees because it has the symbol. and it is given that Angle X 45 degrees. Using the triangle interior angle theoreom, a triangle has 180 degrees so Angle C is 45 degrees. Know let find the sides, First we can deduce XY is 5 cm because of the triangle midsegment theorem XY is half of BC so since we know BC is 10  that means XY is 5.  Then applying 45-45-90 triangle rules, XY=5, YC=5 and XC=[tex]5\sqrt{2}[/tex].

2.Now let look at the triangle XBC. Let find one  missing angles. In the triangle . A  angle bisector  XC bisects XY and BC  . Using that information Angle C of XYC = Angle C of XBC. So angle C=45 degrees. Knowing looking at the main triangle ABC  Angle A=30, Angle C= 45+45=90 and Angle B=60 by interior triangle theorem. So going back to Angle X so angle x is 75 degrees due to interior triangle theorm. Also since Y=90 degrees it forms a linear pair to triangle AXY so Y=90 for AXY

Now let apply 30-60-90 triangle rules to AXY. XY =5, AY=[tex]5\sqrt{3}[/tex] and AX=10.  

Finally. Apply 30-60-90 triangle rules to ABC. AC=[tex]5\sqrt{3}[/tex] +5 BC=10 and AB should turrn out to be 16.9.

This may not be right,but good luck:)

Answer:

a. is congruent by SSS

b. is congruent by AAS

c. is congruent by ASA

d. is congruent by SAS

Step-by-step explanation:

a. is SSS because all sides are marked

b. is AAS because the point where the two triangles meet are vertical angles and the one side of the triangle is marked congruent making AAS

c. is ASA because the angles are on segment FG and segment BC and there is a congruent line in between the two angles making ASA

d. is SAS because the triangles share the segment QS and when two triangles share a segment, that segment is congruent. the outside segment is congruent and then there is an angle and then the inside segment is congruent

Answer: domain:4444

Range: -6, -4, -2, 0

Step-by-step explanation:

X is always the domain, and y is the range

Answer:

m=-2 b=0

Step-by-step explanation:

first, in order to understand anything, you gotta know what y=mx+b means :)

first, m is just there so you can substitute it for a number. x represents the slope, and b represents the y-intercept, which you also substitute for a number.

so in y= -2x, there's no y intercept, because there is no number that represents the y intercept.

so if we use y=mx+b, we can just substitute the numbers.

which would be, y= -2.

Answer:

15/20    16/20    <

Step-by-step explanation:

First, make a common denominator for both, which is 20. So, 3/4 = 15/20. Then 4/5= 16/20. 15/20 < 16/20, so 3/4 < 4/5.

Step-by-step explanation:

In Step 2, the student subtracted 4 on the left side of the equation, but incorrectly added 4 on the right. (The same operation needs to be performed on both sides of the equation.) The correct step 2 would be ...

  -8x = -32 . . . . correct step 2
