A company makes wax candles shaped like rectangular prisms. each candle is 5 cm long, 2 cm wide and 12 cm tall. if the company used 5040 cm^3 of wax, how many candles did they make ?

6x-2.50x-30=40

3.50x-30=40

3.50x=70

x=20 ornaments

Kay has to sell 20 ornaments to get a profit of $40.00.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Cost for the table = $30

Cost for each ornament = $2.50

Selling price of each ornament = $6.00

Profit = Revenue - Expense

Let x be the number of ornaments sold to get a profit of $40.00.

Revenue = 6x

Expense = 30 + 2.5x

6x - (30 + 2.5x) = 40

3.5x - 30 = 40

3.5x = 70

x = 20

Hence selling 20 ornaments would give Kay a profit of $40.00.

The complete question is as follows :

Kay's mother taught her how to make handmade ornaments to sell at a craft fair. Kay rented a table at the fair for $30 and set up her work station. Each ornament that she makes costs approximately $2.50 for materials. She sells each ornament for $6.00.

Kay feels that if she earns a profit of 40.00 at this craft, her business will be successful enough for her to branch out to other craft fairs. How many ornaments does she have to sale to earn a 40.00 profit. Write and solve an equation then explain how the steps and operations used in your algebraic solution compare to an arithmetic solution.

Answer:

sure whats the problem

Step-by-step explanation:

Answer:

1. 7 = 35

The tomato plant will be 35 cm tall after 7 weeks.

2. I don't this is a realistic demonstration of a tomato plant growth, because it is in a table

3. We could use variable h to represent the height of a tomato plant, and I chose this variable because height starts with the letter h.

4. We could use variable w to represent the number of weeks the plant has grown, and I chose this variable because weeks starts with the letter w.

5. 5w = h

6. 5*20 = 100

The tomato plant will be 100 cm tall after 20 weeks.

Answer: [tex]10\ cm^3[/tex]

Step-by-step explanation:

Given

The surface area of a rectangular prism is [tex]34\ cm^2[/tex]

Width of prism [tex]w=1\ cm[/tex]

Length of prism [tex]l=2\ cm[/tex]

height of prism [tex]h=x\ cm[/tex]

Surface area is given by

Put values

[tex]34=2[2\times 1+1\times x+2x]\\17=2+3x\\15=3x\\x=5\ cm[/tex]

Now, the volume of Prism is given by

[tex]V=l\times w\times h[/tex]

[tex]\Rightarrow V=2\times1\times 5=10\ cm^3[/tex]

Step-by-step explanation:

It is assumed the angles A and C are congruent:

m∠A = 3*5 + 40 = 55°

Answer:

solution given:

m<a=m<c

3x+40=x+50

3x-x=50-40

x=10/2=5

now

m<a=55° is your answer

Answer:

A. 1 unit

Step-by-step explanation:

A cube has the same dimensions on each side, and the unit is 1 unit cube, none of the other options match.

You can easily rule out, B & D. That leaves you with A & C, and A makes the most sense, since 1 cubic unit would be the volume, and this question is only asking for the side length.

Good luck, hopefully, this helped!

Required data:

| 60 | 105 | 80 | 125 |

| 140 | 95 | 65 | 170 |

Answer:

Mean absolute deviation = 30

Variability of the data about the mean value is 30

Step-by-step explanation:

Mean = Σx / n

n = sample size = 8

Mean = (60 + 105 + 80 + 125 + 140 + 95 + 65 + 170) = 840 / 8 = 105

Mean absolute deviation = Σ|x - mean| ÷ n

( |60-105| + |105-105| + |80-105| + |125 - 105| + |140-105| + |95-105| + |65-105| + |170-105|) / 8

(45 + 0 + 25 + 20 + 35 + 10 + 40 + 65) / 8

240 / 8

= 30

The variability of data about the central point or mean value is 30.

Answer:

C) (x,y)->(x-8,y+4)

Step-by-step explanation:

Just did it on edge 2021

The translation rule will be (x+8 , y+4).

A transformation is a broad phrase covering four distinct methods of changing the shape and/or position of a point, line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.

When we scale a triangle by some factor, neither its shape nor size change. The image corresponds to the previous image.

The horizontal translation of x coordinate is either horizontally right or horizontally left depending on the positive or negative value of x - coordinate.

Depending on the positive or negative value of the y - coordinate, the y coordinate is translated vertically up or down.

Here (8 ,4) shows there is shifting Horizontally right (x+ 8) and there is shifting Vertically up (y + 4).

Answer:

Mean: 63. Median: 69. Mode: 41. Range: 51.

Step-by-step explanation:

The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers. The "median" is the "middle" value in the list of numbers. To find the median, your numbers have to be listed in numerical order from smallest to largest, so you may have to rewrite your list before you can find the median. The "mode" is the value that occurs most often. If no number in the list is repeated, then there is no mode for the list. The "range" of a list a numbers is just the difference between the largest and smallest values.

Answer:

45

Step-by-step explanation:

Total mini chocolates in a bowl= 85

ration of kit kats to hersheys bars = 8:7

ration of kit = 8

Total ratio= 15

Number of kit kats= ratio of kit Kat/ total ratio × total number of mini chocolates

Number of kit Kat = 8/15 × 85= 45

Hence, there are 45 kit kats present there.

Answer:

There were about 45 kit kats.

Step-by-step explanation:

With the information provided, you know that the the ratio of kit kats to hersheys bars is 8:7 and that there are 85 mini chocolates in a bowl, so to be  able to find the number of kit kats there first you can say that you have 15 units because if you add the numbers on the ratio 8+7=15. Then, you divide the total amount of mini chocolates by the units to find the number of chocolates in each unit:

85/15=5.66

Now, you can multiply the ratio of hersheys bars which is 7 for the number of chocolates per unit to find the amount of hersheys bars:

7*5.66=40

Finally, you can multiply the ratio of kit kats which is 8 for the number of chocolates per unit to find the amount of kit kats:

8*5.66=45

According to this, the answer is that there were about 45 kit kats.
