Jacob sells homemade skateboard decks for a profit of $27 per each one. He is considering switching to a new type of material that will increase his profit (y = 32x0) (where x is the number sold and y is the amount of profit).

How many more dollars will Jacob earn on each skateboard deck if he switches to the new material?
(Please Explain)

Answers

Answer:

I believe it is 32

Step-by-step explanation:

I think this because in your equation it says (y=32x) which 32 will mean how much he is charging for each skateboard, x will be how many he sells, and y would be how much he makes from selling them. So if he sold 2 skateboards you would do.. 32 x 2 which equals 64 soo that would be (64=32x2) so it is 32

Jacob will earn more for each skateboard deck if he switches to the new material is $5.

What is profit?

When something or the cost of manufacturing an object is less than the selling price of the object, then you get a profit.

As it is given that Jacob will increase his profit by 32x where x is the number sold means he will get $32 if he sold one product (32×1).

Before, he gets  a profit of $27 if he sold one skateboard, so,

Let Jacob will earn y amount more than the current material,

y = Profit in new material - Profit in old material

y = 32 - 27

y = $5

Therefore, Jacob will earn more for each skateboard deck if he switches to the new material is $5.

1. The relationship between a distance in yards (y) and the same distance in miles (m) is
described by the equation y = 1760m.
a. Find measurements in yards and miles for distances by filling in the table.
distance measured in miles
distance measured in yards
1
5
3,520
17,600
b. Is there a proportional relationship between a measurement in yards and a
measurement in miles for the same distance? Explain why or why not.

Answers

Therefore, the ratio of yards to miles is always constant, making it a proportional relationship.

What is equation?

An equation is a mathematical statement that shows the equality between two expressions. It typically includes one or more variables, which are unknowns that can take on different values. An equation can be solved by finding the value or values of the variable(s) that make both sides of the equation equal.

Here,

a. Using the equation y = 1760m, we can fill in the table as follows:

distance measured in miles distance measured in yards

1                        1,760

5                8,800

3.520     6,195.2

17,600      30,800,000

b. Yes, there is a proportional relationship between a measurement in yards and a measurement in miles for the same distance. The equation y = 1760m shows that the number of yards is always 1760 times greater than the number of miles. This means that if you double the number of miles, the number of yards will also double, and if you triple the number of miles, the number of yards will triple, and so on.

A carton of two dozen eggs includes three with cracks. How many eggs without cracks can be expected in six dozen eggs?

Answers

Answer:

63

Step-by-step explanation:

because 2 dozens is 24, and since there are three cracked eggs in two dozens, in six dozens, which is 72 eggs, since 24 times 3 is 72, we have to multiply 3 times 3, which is nine, so 9-72,which is 73.

The number of eggs without cracks can be expected in six dozen eggs will be 63.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

A carton of two dozen eggs includes three with cracks.

Crack egg = 3 / (12 x 2)

Crack egg = 3 / 24

Crack egg = 1/8

The number of non-crack eggs is given as,

Non-crack egg = (24 - 3) / 24

Non-crack egg = 7/8

Then the total number of eggs in six dozen is given as,

Total egg = 12 x 6

Total egg = 72

Then the total number of non-crack eggs is given as,

Total non-crack eggs = 72 x 7 / 8

Total non-crack eggs = 63

The number of eggs without cracks can be expected in six dozen eggs will be 63.

1 pound = 16 ounces
Before you try that problem, answer the question below.
How many ounces will you need to find the number of calories for? ( don;t forget Convert the given number of pounds to ounces)

Answers

Answer:

1. considering that there are 16 ounces in one pound, and the question is asking for one pound, I would think that there would only need to be 16 ounces observed.

2. Through calculations of the given number of oz, there are 71 calories per oz. By multiplying that by 16 (the number of oz in a lb) there are a total of 1,136 calories in a lb.

I believe the answer is 1,163 calories, I could be totally wrong..

1/10(x + 11) = -2(8 -x)
please show your steps, will give brainliest.

Answers

Answer:

X = 1.9

Step-by-step explanation:

Distribute first!

1/10(x + 11) = -2(8 - x)

1/10x + 11 = -16 - (-x)

Then simplify (if need be):

1/10x + 11 = -16 + x

Combine like terms:

11 + 16 = 1x - 1/10x

27 = .9x

Divide to get your x by itself:

27/.9 = .9x/.9

or

27/.9 = x

Solve:

X = 30

Answer:

-149/9=x

Step-by-step explanation:

Use distributive property first

1/10x +11/10= -16 +x

move x's to one side and the constants to the other

11/10= -16 +x -1/10x

11/10 -16= 9/10x

simplify the constants

-16x10/10= -160/10 + 11/10= -149/10

-149/10=9/10x

multiply by reciprocal

-1490/90=x

simplify

Television sizes are determined by the length of their diagonal measure. Michael just bought a new television. The height of the television is 37 inches and the length is 71 inches.

Using the Pythagorean Theorem, what is the size of Michael’s new television? Round your answer to the nearest whole inch (whole number).



Part A: What parts of the right triangle have you been given? Are you looking for a leg or the hypotenuse?



Part B: Set-up your equation by substituting the correct numbers into the Pythagorean Theorem formula.



Part C: Solve for the missing length rounded to the nearest whole number. Remember to show ALL work for each step.



Part D: What is the size of the television rounded to the nearest whole inch (whole number)? REMEMBER: We’re looking for the length of the diagonal, as that is the measurement used to determine TV Sizes.

Answers

Answer:

Part A we are given the legs and are looking for the hypotenuse

Part B 37^2 + 71^2 = c^2

Part C 37^2 + 71^2 = c^2

961+5041 = c^2

6002 = c^2

Take the square root of each side

sqrt(6002) = sqrt(c^2)

77.47257579=c

c = 77

Part D The size is 77 inches

Step-by-step explanation:

The pythagorean theorem is a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse

a = 37 and b = 71  were are looking for the diagonal ( or hypotenuse) which is the size

37^2 + 71^2 = c^2

961+5041 = c^2

6002 = c^2

Take the square root of each side

sqrt(6002) = sqrt(c^2)

77.47257579=c

Rounded to the nearest whole number

77 =c

The size is 77 inches
