Answer:

Step-by-step explanation:

4x + 6 = 102

-6. -6

4x= 96

x=24

Sum of all angles of triangle=180°

So, 102 + 4x + 6 + x = 180

or 5x + 108 = 180

or 5x = 180 - 108

or 5x = 72

or x = 72/5

or x = 14.5

So, x = 14.5°

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

Answers

Answer: Choice D

Each vertical line drawn through the graph will intersect a function in only one location.

This is another way of saying that for any input x, there is exactly one output y. If you had a vertical line cross through a curve at multiple points, then this would mean that x input produces multiple y outputs, and we won't have a function. A function must produce one output whatever the input is (assuming the input is in the domain of course).

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

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

-149/9=x

HELP I NEED THIS DONE ASAP IM BEING TIMED

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

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.

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

Answers

Answer:

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.

After much thought, she's seriously considering buying a condominium for $175,000. She intends to put 20 percent down and expects that closing costs will amount to another $5,000; a commercial bank has agreed to lend her money at the fixed rate of 6 percent on a 15-year mortgage. Julie would have to pay an annual condominium owner's insurance premium of $560 and property taxes of $1,000 a year (she's now paying renter's insurance of $550 per year). In addition, she estimates that annual maintenance expenses will be about 0.5 percent of the price of the condo (which includes a $30 monthly fee to the property owners' association).
