A bag contains 120 marbles. Some are red the rest are black. There are 19 red marbles for every black marble. How many red marbles are in the bag?

Answers

Answer 1

Answer:

114

Step-by-step explanation:

Ratio of red marbles to black marbles is 19:1. (Data from 3rd sentence)

19+1= 20

20 units= 120 (Data from 1st sentence)

1 unit= 120/20= 6

19 units= 120-6= 114 (Values solved in working above)

Ans: There are 114 red marbles.

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. The value of Tan(B) will be equal to 8/15.

What is Tangent (Tanθ)?

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,

[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

The base is the adjacent smaller side of the angle θ.

The value of Tan(B) will be the ratio of the sides AC and BC. Therefore, the value of Tan(B) can be written as,

Tan(B) = AC / BC

Tan(B) = 8/15

Hence, the value of Tan(B) will be equal to 8/15.

Randi shovels and salts her neighbors' driveways and walkways to earn money during the winter months in her town near the Pocono Mountains. She charges $25 dollars per hour because the amount of time she spends shoveling and salting depends on the size of the driveway and walkway.

Randi has to pay for the salt that she uses, which costs her $3.00 per job on average. She also saves $2.00 per job to cover the costs of replacement shovels as needed.

Randi's profit is the total amount of money that she collects from a snow shoveling and salting job that takes t hours minus her costs.

Randi earned a profit of $60.00 on her last snow shoveling and salting job. Write an equation that can be solved to find how many hours Randi spent shoveling and salting to earn a profit of $60.00.Write your answer in the form of an algebraic equation using the math editor. You do not have to solve the equation, but you will need to use your equation to complete the next test question.

Answers

Answer:

25t = 65

Step-by-step explanation:

Given that :

Profit earned = $60

Charge per hour = $25

Randy's cost or expenses = $(2 + 3) = $5 per job

Profit = (charge per hour * t) - cost

Where t = time

$60 = ($25 * t) - $5

$60 = $25t - $5

$25t = $65

Step-by-step explanation:

since it takes her 0.6 miles to walk an hour and an hour to walk 0.6 miles.

0.6 = 3/5

Answer: 0.1 miles per hour

Since an hour has 6 10-minute segments, divide by 6.

0.6 ÷ 6 = 0.1

Your answer should be 0.1 miles per hour.

So, Angela and her dog are walking at 0.1 miles per hour.

negative 6 over 8 minus negative 1 over 8 = negative 5 over 8; therefore, the distance from A to B is absolute value of negative 5 over 8 equals negative 5 over 8 units

Because it is 3 units to the left of 2 on a horizontal number line

Step-by-step explanation:

The answers are the explanation.

Comment on the second question

Note that the second question asks for the distance from -6/8 to -1/8. Ordinarily, the distance from A to B would be computed as B - A. In this set of answer choices, it is computed as |A - B|. In the end, the result is the same.

Personally, I would compute the distance between points on a number line by subtracting the left point from the right point. Here, that would also correspond to B - A.

Comment on choosing 'word' answers

In a set of answers like these, one way to choose answers is simply to eliminate the ones that make a false statement. Often, you are left with only the correct answer choice.

For example, the statement "the additive inverse of -3 is -3" is a false statement, so the first two answer choices can be eliminated. Likewise, the statement 16 -(-3) = 13 is false, so that choice can be eliminated. The one remaining answer is the correct one.

n - 4 = 3n + 6
what number does n represent?

Answers

Answer:

n = -5

Step-by-step explanation:

n - 4 = 3n + 6

n = 3n + 10

-2n = 10

n = -5

Answer:

-5

Step-by-step explanation:

Lets start by combining some common terms. -4 can be brought over to the right as +4 and 3n can be brought to the left as -3n to make the statement -3n +n = 6+4

Simplifying that, we get -2n = 10

Dividing 10 by -2, we get n = -5

Pete bought a 16-ounce box of cereal for $3.58. What was the cost per ounce?

Answers

Answer:

Around 0.22 dollars or 22 cents

Step-by-step explanation:

We know that per 16 ounces it costs 3.58. We want the ounces to equal zero. To do that, we divide 16 by 0, but to keep it equal we need to divide 3.58 by 16. So...

16/16 = 1

3.58/16 = 0.22375

This means that every ounce of cereal, it costs 0.22375 dollars, but money can't go in the thousandths place, so we must round it to the hundredths place, which becomes 0.22 dollars, or 22 cents. I hope this helps and I hope it's not wrong but I don't think it is.

Answers

Answer:

Move three units left on the x axis and 4 units up on the y axis from the origin

Step-by-step explanation:

Answer:

B.

Step-by-step explanation:

That is because ordered pairs are written as (x,y) and for the ordered pair (3,4), 3 is x and 4 is y. The x-axis is the horizontal (left and right) line, the y-axis is the vertical line (up and down). The numbers are positive, so you go 3 units right and 4 units up.  

Brad is going on a vacation with his family. He will be going through six states on his trip, but traveling only 900 miles. The vacation will last 23 days. While brad is pleased to be missing school, his teacher has asked him to write in his journal half of a page each day of his trip. How many pages would he have written by the time he gets back home

Answers

The number of pages that he would have written by the time he gets back home is 46 pages.

How to calculate the value?

From the information given, the expression was illustrated that the vacation will last 23 days. While brad is pleased to be missing school, and his teacher has asked him to write in his journal half of a page each day of his trip.

The appropriate equation to represent this will be:

p = 23 / 1/2

where p = number of pages

p = 23 ÷ 1/2

p = 23 × 2

p = 46

The number of pages is 46

Answer:

5/6

Step-by-step explanation:

Please help this fairly quick

Answers

Answer:

A) true

B) false

c) true

d) true

Step-by-step explanation:

A) angles 7 and 6 are vertical angles, which means they're equal.

so, A is True.

B) angles 7 and 5 are supplementary angles, which means they add up to 180. 135 + 55 is 190. so B is False

C) angle 7 is equal to angle 3, which is supplementary to angle 1.

so, 55 + angle 1 = 180

55 + angle1 = 180

subtract 55 from both sides of the equation

angle1 = 180 - 55

angle 1 = 125.

angles a and 4 are vertical angles, so they are equal. if you add them together that would be 125 + 125

125 + 125 = 250

so, C is True

D) angles 1 and 6 are supplementary, and angles 2 and 7. since they both add together to make 180, D is True
