Jennifer uses the formula P = 0.5e - 5 to determine the profit (P) she makes from selling any number of erasers (e). Last week Jennifer had a profit of $63. How many erasers did Jennifer sell?

Answers

To find this answer we must plug in the values given and then rearrange the equation to solve for e (number of erasers). First we can rearrange the equation for e to get the following expression: (P + 5)/.5 = e . Now we just plug in the $63 profit for P and solve for e. Doing this we get: (63 + 5)/.5 = 68/.5 = 136. Jennifer sold 136 erasers.

a line contains the points (82,-96) and (87,-86)
what is the sloped line is simplified form?

Answers

Slope formula: y2 - y1 ÷ x2 - x1
Let's label the points. (82[x1], -96[y1]) (87[x2], -86[y2])
-86 - -96 would turn into -86 + 96, coming out to 10. 
87 - 82 = 5.
10/5 would be the unsimplified slope.
Divide both numbers by 5, and you get 2/1.
2/1 simplifies to 2 because two divided by one equals two, as one can go into two twice.

the marching band is having a show to raise at least $1000 forntheir upcoming trip. Each adults is $6 and students $4. The auditorium has a maxium capacity of 200 people.

Answers

This question is incomplete. I assume that you are looking for the number of adults and students.

Let a = adult

Let s = student

6a + 4s = 1000...A
a + s = 200...B

We have a system of linear equations in two variables, the variables a and s.

You can select any variable of choice to represent the adults and students.

Solve equation B for a or s (your choice).

a + s = 200

Solve for a or s (your choice).

s = 200 - a

Plug into equation A to find the value of a.

6a + 4(200 - a) = 1000

6a + 800 - 4a = 1000

6a - 4a = 1000 - 800

2a = 200

a = 200/2

a = 100

There are 100 adults.

Plug a = 100 into EITHER equation A or B to find students.

a + s = 200

100 + s = 200

s = 200 - 100

s = 100

There are also 100 students.

How long does it take each horse to run a mile

Answers

The correct answer is;

Horse A will take 4 minutes to run 1 miles, while horse B will take 2 minutes 30 seconds to run 1 mile.

Analysing the graph, the Distance is measured in miles, while the Time is measured in minutes.

For horse A, the time taken to run 1 miles is 4 minutes, according to the graph.

For horse B, the time taken to run 1 mile is 2 minutes 30 seconds according to the graph.

Therefore, according to the graph, it will take horse A and horse B, 4 minutes and 2 minutes 30 seconds respectively, to run a mile.

The table below shows the number of pencils of different colors in a box:

Pam draws a color pencil from the box randomly without looking. What is the probability that Pam will select a yellow pencil and the coin will land tails up?
2 over 40
6 over 40
12 over 20
16 over 20

Answers

Answer:

6 over 40

Step-by-step explanation:

6/40 or 3/20  is the probability that Pam will select a yellow pencil and the coin will land tails up.

What is probability?

Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

Given that,  The table below shows the number of pencils of different colors in a box:

Color of Pencil        Number

Purple                         10

Blue                             1

Yellow                         6

Pink                             3

From the general formula of probability:

Probability = (desired outcome)/ (Total outcome)

In our case

Total outcomes = (number of pencils) * (coin sides)

Total outcomes = 20 * 2

Total outcomes = 40

Desired outcomes = Pam will select a yellow pencil and the coin will land tails up

Desired outcome = (number of yellow pencils) * (coin sides)

Desired outcome = 6 * 1 = 6

Thus,

Probability = 6/40

therefore, the probability that Pam will select a yellow pencil and the coin will land tails up is 6/40 or 3/20.

angle P and angle Q are supplementary. If angle P = 2x and angle Q = x-3, find X

Answers

2x+x-3=180
3x-3=180
3x=183
x=61

The angles P and Q are supplementary, meaning together they add up to 180 degrees. Based on the given expressions for these angles, solving for x yields x equals 61.

The given problem describes supplementary angles P and Q. Supplementary angles are two angles whose measures add up to 180 degrees. In this case, angle P is represented by 2x and angle Q is represented by x-3. The equation representing these supplementary angles is therefore 2x + (x - 3) = 180.

Combining similar terms, this equation simplifies to 3x - 3 = 180. To solve for x, add 3 to both sides obtaining 3x = 183. Finally, divide each side by 3 to find x = 61.

Ella and Margaret were at a carnival. They each got a ticket to the Ferris wheel. Ella got a snow cone, and Margaret got a cotton candy. Ella had a certificate for $6 off the cost. Margaret paid the rest, which came to $12.75. Each Ferris wheel ticket is $5. And a snow cone is $3.50. What was the cost of the cotton candy? A.$5.00 B.$5.25 C.$2.50 D.$7.25

Answers

the answer is B. $5.25

Answer:

B.$5.25

Explanation:

There were 2 tickets to the Ferris wheel; each is $5.  This can be written as 2(5).

Ella got a snow cone, which cost $3.50.  This gives us 2(5) + 3.50.

Margaret got a cotton candy, the cost being unknown; this gives us 2(5)+3.50+x.

Ella had a certificate for $6 off the cost; this gives us 2(5)+3.50+x-6.

This makes the equation

2(5)+3.50+x-6=12.75

Combining like terms, we have

7.50+x = 12.75

Subtract 7.50 from each side:

7.50+x-7.50 = 12.75 - 7.50

x = 5.25

Answer:

Option C.

Step-by-step explanation:

The given expression is

[tex]-\frac{1}{3}-(-\frac{1}{2})[/tex]

We know that (-)(-)=(+). So, the given expression can be written as

[tex]-\frac{1}{3}+\frac{1}{2}[/tex]

Taking LCM we get

[tex]\frac{-2+3}{3\times 2}[/tex]

[tex]\frac{1}{6}[/tex]

The value of given expression is 1/6.

Two numbers are [tex]-\frac{1}{3}\text{ and }-\frac{1}{2}[/tex]. Mark these point on the given number number.

Now, move from [tex]-\frac{1}{2}[/tex] to [tex]-\frac{1}{3}[/tex] and count the number of jumps.

Number of jumps from [tex]-\frac{1}{2}[/tex] to [tex]-\frac{1}{3}[/tex] is 1.

1 Jump = 1/6

Therefore, the value of given expression is 1/6, therefore the correct option is C.

4.5(8-x)+36=102-2.5(3x+24) show step by step how to solve please.

Answers

Distribute 4.5 to 8- x and distribute -2.5 to 3x-24 to get 36-4.5x+36+102-7.5x+60, then add like terms to get  3x=90
Simplifying 4.5(8 + -1x) + 36 = 102 + -2.5(3x + 24) (8 * 4.5 + -1x * 4.5) + 36 = 102 + -2.5(3x + 24) (36 + -4.5x) + 36 = 102 + -2.5(3x + 24) Reorder the terms: 36 + 36 + -4.5x = 102 + -2.5(3x + 24)

Combine like terms: 36 + 36 = 72 72 + -4.5x = 102 + -2.5(3x + 24)

Reorder the terms: 72 + -4.5x = 102 + -2.5(24 + 3x) 72 + -4.5x = 102 + (24 * -2.5 + 3x * -2.5) 72 + -4.5x = 102 + (-60 + -7.5x)

Combine like terms: 102 + -60 = 42 72 + -4.5x = 42 + -7.5x Solving 72 + -4.5x = 42 + -7.5x Solving for variable 'x'.

 Move all terms containing x to the left, all other terms to the right.

 Add '7.5x' to each side of the equation. 72 + -4.5x + 7.5x = 42 + -7.5x + 7.5x

Combine like terms: -4.5x + 7.5x = 3x 72 + 3x = 42 + -7.5x + 7.5x

Combine like terms: -7.5x + 7.5x = 0.0 72 + 3x = 42 + 0.0 72 + 3x = 42

Add '-72' to each side of the equation. 72 + -72 + 3x = 42 + -72

Combine like terms: 72 + -72 = 0 0 + 3x = 42 + -72 3x = 42 + -72

Combine like terms: 42 + -72 = -30 3x = -30

Divide each side by '3'. x = -10

Simplifying x = -10

The value of 2036017 in expanded form using exponent is expressed as  (2 × 10⁶) + (3 × 10⁴) + ( 6 × 10³) + 10¹ + 7

Given the value 2036017, we are to express it in expanded form as shown:

2036017 = 2,000,000 + 30000 + 6000 + 10 + 7

Express each term as exponents

2,000,000 = 2 × 10⁶

30000 = 3 × 10⁴

6000 = 6 × 10³

10 = 10¹

Taking the sum of the exponents

2036017  = (2 × 10⁶) + (3 × 10⁴) + ( 6 × 10³) + 10¹ + 7

Hence the value of 2036017 in expanded form using exponent is expressed as  (2 × 10⁶) + (3 × 10⁴) + ( 6 × 10³) + 10¹ + 7

A package of 5 pairs of insulated gloves costs 29.45 what is the cost of a single glove?

Answers

5 pairs of gloves, two gloves per pair, so we have 10 gloves.
If the entire pack cost $29.45, we divide that by 10 to determine the cost of a single glove:

$29.45 ÷ 10 = $2.945 which rounds to $2.95 per glove.

Given that the package contains 5 pairs of gloves

Let us first establish some facts

We know that a pairs consist of 2 glovesIn all we have 10 gloves

Now let us solve for the cost of a glove

if 10 gloves cost 29.45

the 1 glove  will cost x

Cross multiply to solve for x

10*x = 1*29.45

divide both sides by 10

x = 29.45/10

x= 2.945

Hence the cost of a single glove is 2.945
