Two eighth-grade classes are selling chocolate bars to raise money for an end-of-year field trip. One class is selling chocolate bars for $3.00 each and has already raised $275.00. The other class is selling chocolate bars for $3.50 each and has already raised $250.00. Which equation can be used to calculate c, the number of additional chocolate bars each class needs to sell, so that the total amount raised is the same for both classes?

Answers

Answer 1

Answer:

Step-by-step explanation:

you add both $275.00 and $250.00 ($525.00) then and $3.00 and $3.50 ($6.50) then divide $525.00 by $6.50 and then you answer would be $88.00

so c = $88.00

Answer 2

Answer:

3.50c + 250.00 = 3.00c + 275.00

3. Write an equation in point-slope form that describes the line with a slope of 2 that contains the point (4,-3)?

Answers

Answer:

y + 3 = 2 (x - 4)

Step-by-step explanation:

y - y₁ = m (x - x₁)

substitute (4, -3) in for (x₁, y₁)

y - (-3) = m (x - 4)

substitute the slope (2) in for m (m=slope) and simplify (y - (-3)) to (y +3) because subtracting a negative is the same as adding a positive

y + 3 = 2 (x - 4)

and that's your final answer! hope this helped :)

Joshua tells his friends that for there to be snow it has to be 32o F. He uses his thermometer outside and sees snow. He finds it is only is 34oF. What is his percent error? (Round to the nearest tenth)

Answers

Answer: Percentage error = -5.9%

Step-by-step explanation:

Step 1

Percentage error =Approximate Value − theoretical  Value / Theoretical value    ×  100%

or

Percentage error = Assumed number - Result number / Result number x 100

Given  Assumed number / Approximate Value=  32o F

Result number/ Theoretical value= 34o F.

Step 2---

Percentage error = (32 - 34)/ 34  x 100

= - 2/34 x 100

= - 5.88%

Joshua  was in error by - 5.88 % which when rounded to nearest tenth gives - 5.9%.

Step-by-step explanation:

Answer:

A. y = -2x + 2

Step-by-step explanation:

4x + 2y = 4

Move 4x to the other side of the equation.

2y = 4 - 4x

Divide the whole thing by 2 to get y by itself.

y = 2 - 2x

which can also be written as

y = -2x + 2

There are 80 tickets in a bag and the ratio of winning tickets to losing tickets is 2 : 8. How many of each kind of ticket are in the bag?

Answers

Given:

Total number of tickets = 80

Ratio of winning tickets to losing tickets is 2 : 8.

To find:

The number of tickets of each kind in the bag.

Solution:

Let the number of winning and losing tickets are 2x and 8x respectively.

Total number of tickets = 80

[tex]2x+8x=80[/tex]

[tex]10x=80[/tex]

Divide both sides by 10.

[tex]x=\dfrac{80}{10}[/tex]

[tex]x=8[/tex]

Now,

Winning tickets : [tex]2(8)=16[/tex]

Losing tickets : [tex]8(8)=64[/tex]

Therefore, the winning and losing tickets are 16 and 64 respectively.

In triangle ABC, we can draw a perpendicular line segment from vertex C to segment AB. The intersection of AB and the perpendicular is called E. We know that BE is the shortest distance from B to and that is the shortest distance from A to CE because of the shortest distance theorem. Therefore, BC > BE and AC > AE. Next, add the inequalities: BC + AC > BE + AE. Then, BE + AE = BA because of the . Therefore, BC + AC > BA by substitution.

What is the percent of change from 5 to 9?

Answers

Hey there! It would be 44% decrease...

Explanation:

So we know that 9 would be 100%. So what is the percent of change?

So let divide 5 with 9. 5 divide 9 would be 0.56.

Great, now we can subtract 100 with 0.56 since we know that 56% is 5. 100-56 is 44. This means that the percent decrease would be 44%.

Final Result: 44%

The percent change from 5 to 9 is 80%.

What is percentage?

Percentage is a measurement to find the value of a given number out of hundred.

Given that,

The original number is 5.

The number changes to 9 .

Increase in number = 9-5 = 4

The percentage change = 4/5×100 = 400/5 = 80%

The percentage change is 80% from 5 to 9.

At Pizza pizzazz the cost of a square pizza depends on the total square inches. A small

Pizza is 5 inches on each side and cost four dollars plus $0.05 per square inch. A medium pizza is 8 inches on each side and cost $3.50 plus $0.04 per square inch. What is the difference in price between a small pizza and a medium pizza?

Answers

Answer:

The difference in price between a small pizza and a medium pizza is $0.81

Step-by-step explanation:

Small pizza

Side = 5inch

Area =  25 sq.in

Cost = $4 +0.04*25

        = 4 + 1.25  = $5.25

Medium pizza

Side = 8inche

Area = 64 sq.in

Cost = 3.50 + 0.04*64 = $6.06

Difference = Medium pizza - small pizza

                  = 6.06 - 5.25

                   = $0.81
