Step-by-step explanation:

It is 5 because no matter how many stamps he sells, he has $5.

Answer:

The y-intercept of Ben's graph is [tex]y = 5[/tex].

Step-by-step explanation:

The function for Ben's amount of money y, depending on the number of stamps sold x, is as follows:

[tex]y = ax + b[/tex]

In which a is the price of each stamp and b is his initial money.

Building the function:

Ben has $5. This means that if he sells no stamps, he is still going to have $5. So [tex]b = 5[/tex].

For each stamp sold, he gains $3. So if sells 1 stamp, he will have $8, if he sells 2, he will have $11. So [tex]a = 3[/tex].

The function is:

[tex]y = 3x + 5[/tex]

Which will be the y-intercept of Ben's graph?

This is the value of y when x = 0.

So

[tex]y = 3*0 + 5 = 5[/tex]

The y-intercept of Ben's graph is [tex]y = 5[/tex].

The expected value of store card transactions will be the product of their average value ($58) and their probability of occurrence (48%).

... $58 × 0.48 = $27.84

Transactions are either "store card" or "without a store card", so the probability of a transaction being made without a store card is

... 1 - 0.48 = 0.52

Using the same computatation as for store card expected value, the expected value of transactions made without a store card is ...

... $74 × 0.52 = $38.48

The expected value of the store's transactions is the sum of the expected values of the different ways transactions can be made:

... $27.84 +38.48 = $66.32

_____

The average value of transactions made without a store card is the weighted average of those made with another card and those made with cash or a gift card. Using c to represent the latter, this weighted sum is ...

... 74 = 0.80 × 70 + 0.20 × c

... 74 -56 = 0.20c . . . . . subtract 56

... 18/0.2 = c = 90 . . . . . divide by the coefficient of c

The average transaction made with cash or a gift card is $90.

Each expected value per transaction should be matched to the correct location on the tree diagram as shown in the image below.

In this exercise, we would use probability to make each of the decisions. The expected value for transactions made with a store card can be determined by multiplying its probability of occurrence (48%) by the average value ($58) as follows;

Expected value per transaction = 58 × 0.48

Expected value per transaction = $27.84

Since transactions are either made with a store card or without a store card, the probability of a transaction being made without a store card is given by;

Probability (without a store card) = 1 - 0.48 = 0.52

In this context, the expected value per transactions made without a store card is given by;

Expected value per transaction = 74 × 0.52

Expected value per transaction = $38.48

... $74 × 0.52 = $

For the store's expected value transactions, we would add each of the expected values calculated above;

Store's expected value transactions = 27.84 + 38.48

Store's expected value transactions = $66.32.

The average transaction value for transactions that are made with cash or a gift card can be calculated by finding the weighted average of all transactions made without a card;

74 = (0.80 × 70) + 0.20 × m

74 = 56 + 0.20m

0.20m = 74 - 56

0.20m = 18

m = 18/0.20

m = $90.

Answer:

[tex]1.13x[/tex]

Step-by-step explanation:

We have been given that Camacho is buying a monster truck. The price of the truck is x dollars, and he also has to pay a 13% monster truck tax. We are asked to find the total amount paid by Camacho for the monster truck.

The total cost of monster truck would be x plus 13% of x.

[tex]\text{The total cost of monster truck}=x+\frac{13}{100}x[/tex]

[tex]\text{The total cost of monster truck}=x+0.13x[/tex]

[tex]\text{The total cost of monster truck}=1.13x[/tex]

Therefore, Camacho paid [tex]1.13x[/tex] dollars in total for the truck.

Final answer:

To find the total cost of the monster truck, convert the 13\% tax to decimal form (0.13), multiply it by the price of the truck (xx dollars), then add the result to the original price to get the total cost, which is 1.13xx.

Explanation:

To determine the total amount Camacho will pay for the monster truck, we need to calculate the sales tax and add it to the original price of the truck. The sales tax is 13\%, which can be converted to a decimal for calculation purposes. First, convert 13\% to a decimal by dividing by 100, which gives us 0.13. Then multiply 0.13 by the price of the truck (xx dollars) to find the amount of tax Camacho will have to pay.

After calculating the tax, you can find the total cost by adding the tax to the original price of the truck.

Step 1: Convert 13\% to a decimal = 0.13
Step 2: Multiply the price of the truck (xx dollars) by 0.13 to find the tax = 0.13 * xx
Step 3: Add the tax to the original price to find the total cost: xx + (0.13 * xx).

Total cost = xx + 0.13xx = 1.13xx

Answer:

10 Valentines

Step-by-step explanation:

1/2 = 4/8

3/4 = 6/8

Julie has a total of 4/8 + 6/8 = 10/8 yards of ribbon. If color doesn't matter, she can make 10 Valentines.

_____

10/8 = 10 × 1/8

The slope of AB is ...

... slope = (change in y)/(change in x) = (-6-(-3))/(8-2) = -3/6 = -1/2

The slope of AD is ...

... slope = (change in y)/(change in x) = (0 -(-3))/(8 -2) = 3/6 = 1/2

We note that the differences have the same magnitudes in both cases (y changes by 6; x changes by 3). This tells us the line segments are the same length. (Each side of the figure is equivalent to the hypotenuse of a right triangle with legs 3 and 6.)

The opposite reciprocal of a number is found by dividing -1 by that number. Thus the opposite reciprocal of the slope of AB is ...

... -1/(-1/2) = (-1/1)·(-2/1) = 2

This value is not the same as the slope of AD, so the slopes are NOT opposite reciprocals.

_____

Plotting the points, we see that we have a rhombus, not a rectangle (or square).

None of the above. All the answers refer to price. The given equation refers to value. We imagine price may stay the same or actually increase year-to-year. The problem statement gives insufficient information to conclude anything about price.

Math is about attention to detail. The equation tells you ...

... The value of the boat decreases by 12% every year.

The value of the boat is multiplied by 0.88 each time X increases by 1. That means the value is 88% of what it was the year before, a decrease of 12%.

7. Law of cosines

a² = b² + c² - 2bc cos A

where a is the side opposite to ∠A and b and c are adjacent sides to ∠A.

Here, a=BC= 3.8

b=CA =4.8

c = AB = 3.2

Substituting the values in the formula,

3.8² = 4.8² + 3.2² - 2(4.8)(3.2) cos A

30.72 cos A =23.04 + 10.24 -14.44=18.84

cos A = 18.84/30.72 = 0.6133

∴ cos A =0.6133

8. It is a right angled triangle.

Pythagoras theorem

hypotenuse² = Perpendicular² + base²

Here, hypotenuse = 6.7, base = 5.4

Perpendicular² = 6.7² -5.4²=44.89 - 29.16 =15.73

Perpendicular = √15.73 = 3.966 = 3.97

∴ The length of the missing side is 3.97.

9. Given:   Side of new cube = 5 * Side of original cube

Let the side of the original cube measure 1 unit.

So, volume of original cube = side³ = 1

The side of new cube = 5 * 1 =5 units

So, volume of new cube = side³ = 5³ =125

The volume of the bigger cube is 125 times larger than the original cube.

10. Given : Height of the cone = 7 in

Radius of the base of the cone = 2 in

Volume of cone = (1/3) πr²h

                           =(1/3)π(2²)(7)

                           =29.32 cubic inches

∴ Volume of the cone is 29.32 cubic inches.

11. The given equation is:

x² -18x +10 =0

(x² -18x + 9²) +10 -9² =0

(x-9)²-71 =0

(x-9)² =71

x-9 =√71

x = 9 + √71

∴ x = 9+√71

To find the number of hours Liam volunteered during the first month, we can set up an equation using the given information. By solving the equation, we find that Liam volunteered for 15 hours during the first month.

To solve this problem, we can start by representing the number of hours Liam volunteered in the first month as x. The number of hours volunteered in the next month would be 1 2/3 times x, which can be written as (5/3)x. The total number of hours volunteered is given as 40, so we can write the equation: x + (5/3)x = 40. To solve for x, we can combine the like terms and solve the resulting equation.

Combining the x terms, we get (8/3)x = 40. Solving for x, we divide both sides of the equation by 8/3: x = 40 / (8/3).

Simplifying, we have x = 40 * (3/8) = 15. Therefore, Liam volunteered for 15 hours during the first month.

By representing the number of hours in the first month as x, we can find the value of x by using the given information and solving the equation. The solution shows that Liam volunteered for 15 hours during the first month.

To solve this problem, we can set up an equation representing the total number of hours Liam volunteered. Let's represent the number of hours he volunteered in the first month as x. According to the problem, he volunteered for 1 2/3 times as many hours in the next month. So, the number of hours he volunteered in the next month is 1 2/3 x. The total number of hours is given as 40. Therefore, we have the equation:

x + 1 2/3 x = 40

To solve for x, we can simplify the equation by converting 1 2/3 to an improper fraction. This gives us:

5/3 x + 1 2/3 x = 40

Combining like terms, we get:

8/3 x = 40

To solve for x, we can multiply both sides of the equation by the reciprocal of 8/3, which is 3/8. This gives us:

x = (40)(3/8) = 15

Therefore, Liam volunteered for 15 hours during the first month.

Answer:

a. x = 1, y = -2

Step-by-step explanation:

The given equations are 2x + 3y = -4 -------------(1)

x - 2y = 5 -----------------(2)

From the second equation, we get x = 2y + 5

Now plug in x = 2y + 5 in the first equation, we get

2(2y + 5) + 3y = - 4

4y + 10 + 3y = -4

7y + 10 = -4

7y = -14

y = -2

Now plug in y = -2 in x = 2y + 5 to find the x value.

x = 2(-2) + 5

x = -4 + 5

x = 1

Therefore, x = 1, y = -2

Step-by-step explanation:

... BO/OD = AO/OC = 3/1

Written another way, this is ...

... OD : BO = 1 : 3

Now, BD = OD + BO, so we have

... BD : BO = (OD +BO) : BO = (1 +3) : 3 = 4 : 3

That is, BD = 4/3 × BO

... BD = 4/3 × 6 cm = 8 cm

To find the length of diagonal BD in trapezoid ABCD, we set up an equation using the fact that the diagonals bisect each other. We solve for x and then substitute it into the equation for BD.

To find the length of diagonal BD in trapezoid ABCD, we can use the fact that the diagonals of a trapezoid bisect each other. Let AO = 3x and OC = x. Since the diagonals intersect at point O, we can set up the equation (3x + 6) / x = 3 / 1. Solving for x, we find that x = 1.5. Therefore, BD = 2 * x + 6 = 2 * 1.5 + 6 = 9 cm.

Answer:

slope = .4

She ran .4 laps per min.

She ran 12 laps in 30 minutes

Step-by-step explanation:

The slope is the rate of change.  It can be found by using the formula

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

 The given points are (11, 4.4)  (5.5 ,2.2)

slope = (2.2-4.4(/ (5.5-11)

           = -2.2/-5.5

          .4

The slope represents .4 laps per min  since y is in laps and x is in minutes.

If she  ran 30 minutes, we multiply the time by the slope to calculate the laps.

30 * .4 = 12

She ran 12 laps.

A) The slope is the change in Y over the change in X.

Using the 2 points given on the graph (11,4.4) and (5.5, 2.2)

The first number in the parenthesis are the X value and the 2nd numbers are the Y values.

Slope = (4.4 - 2.2) / (11-5.5)

= 2.2 / 5.5

= 0.4

B) From the slope, she ran 0.4 laps per minute.

C) To find the total laps, multiple laps per minute by total minutes:

30 minutes x 0.4 laps per minute = 12 laps.
