The constant of proportionality in terms of the cost per text is the coefficient of [tex]t[/tex] in the equation [tex]b=0.25t[/tex]. Since the coefficient of [tex]t[/tex] is 0.25, the constant of proportionality in terms of the cost per text is 0.25.
Proportionality constants are usually expressed as fractions, so lets convert 0.25 to a fraction. To do that we are going to add the denominator 1 to our decimal, and then we will multiply both numerator and denominator by ten for every number after the decimal point:
[tex] \frac{0.25}{1} [/tex]
[tex] \frac{0.25}{1} . \frac{100}{100} = \frac{75}{100} [/tex]
Finally, we can simplify our fraction:
[tex] \frac{25}{100} = \frac{1}{4} [/tex]

We can conclude that the constant of proportionality in text of the cost per text is 1/4

Answer:

5 is a constant. (it has no variables)

x + 2 is not a constant. It does, however, have two terms, x and 2.

(terms are seperated by addition/subtraction)

This rules out a and b.

a cylindrical container can hold about 1,256 cubic inches of water.the diameter of the cylinder is 10 inches long.approximate the height of the cylinder to the nearest inch.use 3.14 to approximate the value for pi
A.16
B.80
C.40
D.4

Answers

Answer: A. 16 inches

Step-by-step explanation:

The volume of the cylinder is given by :-

[tex]\text{Volume}=\pi r^2h[/tex]

Given: Diameter of cylinder =  10 inches

Thus, radius of cylinder = [tex]\frac{10}{2}=5\ inches[/tex]

Let h be the height of the  cylindrical container.

Then , The volume of the cylindrical container is given by :-

[tex]1256=\pi (5)^2h\\\\\Rightarrow\ h=\frac{1256}{5^2\pi}\\\\\Rightarrow\ h=\frac{1256}{25\times3.14}\\\\\Rightarrow\ h=16}[/tex]

Hence, the height of the  cylindrical container = 16 inches.

Answer:

To find the odds first find the total 20+44+30=94 and find the odds so there are 44 orange markers that is 44/94

at the park, 4/7 of the children are boys. if there are 8 boys at the park, how many are girls?

Answers

There are 4/7 boys, so there are 3/7 girls.

Let the total number of children be x.

4/7x = 8
1/7x = 8 ÷ 4
1/7x = 2
3/7x = 2 x 3
3/7x = 6

There are 6 girls.
6 because 4/7 boys means a ratio of 4:3, so twice 4 to make 8 means twice 3 to make 6.

Cylinders A and B are congruent. Cylinder A has a volume of 27π cm3 and a height of 3 cm. What is the area of the base of cylinder B?

Answers

To find this answer you would use the formula for finding the volume of a cylinder. Because both of these cylinders are congruent, the area of the base for cylinder A I would also be the same area for cylinder B. V=pi x r^2 x h. When we substitute in what we know this is the new equation: 27 x pi = pi x r^2 x 3. Divide both sides by three and pi. This gives us 9 = r^2. Take the square roots of both sides to find the radius. The answer would be 3. Now use the formula for area of a circle to find the area of the base of cylinder B. A= pi x r^2. So the area would be 9 x pi.

Answer:

9pi

Marlene's taxable income is $95,000. Use this tax schedule to calculate the total amount she owes in taxes. $12,888.75

Answers

Marlene owes a total of $20,710.75 in taxes.

If we are using the same tax schedule then $95,000 belongs to this bracket:
Over -        But not over -                                             of the excess over -
$77,100     but not over $160,850.. 15,698.75 plus 28%            77,100

Get the 28% of the difference between $95,000 and $77,100:
$95,000 - $77,100 = $17,900
$17,900 * .28 = $5,012

$15,698.75 + $5,012 = $20,710.75

Answers

You'd need to know the degrees of a quadrilateral which is, 360 degrees.

I'm going to represent x as the degrees we need to find:

31+83+146+x=360

A cylindrical rain barrel with a diameter of 2.5 feet and a height of 3.5 feet is filled to a height of 1.5 feet. How many more gallons of water can the barrel hold? Round your answer to the nearest whole number. (1 ft3≈7.5 gal)

Answers

To answer this question you will need to find the total volume the rain barrel can hold. Then find the volume of water that it is currently holding.

Subtract these two amounts to find the total amount of water or can still hold.

Then convert this amount to gallons.

1. V = pi x r^2 x h
3.14 x 1.25^2 x 3.5
V = 17.17 cubic feet

2. Same formula
3.14 x 1.25^2 x 1.5
V = 7.36 cubic feet

3. 17.17 - 7.36 = 9.81 cubic feet

4. 9.81 x 7.5 = 73.575 gallons or approximately 74 gallons.

Kylie is on a swing the swing moves back and forth every 5 seconds. About how many minutes would it take Kylie to go back and forth one hundred times? Can you help me figure the minutes out in a fraction?

Answers

31/2 is what i got....its like 87% right

The fraction of the total time in minutes is therefore 8 1/3 minutes, which is equal to 25/3 minutes when expressed as an improper fraction.

To determine the amount of time it would take for Kylie to swing back and forth 100 times, we must first understand that the period of the swing, the time it takes to complete one full cycle back and forth, is 5 seconds. Therefore, we can calculate the total time for 100 swings by multiplying the period by the number of swings:

Total time (seconds) = Period (seconds per swing) * Number of swings

Total time (seconds) = 5 seconds/swing * 100 swings

Total time (seconds) = 500 seconds

To convert seconds into minutes, we divide by the number of seconds in a minute, which is 60:

Total time (minutes) = Total time (seconds) / 60 seconds/minute

Total time (minutes) = 500 seconds / 60 seconds/minute

Total time (minutes) = 50/6 or approximately 8 minutes and 20 seconds.

The fraction of the total time in minutes is therefore 8 1/3 minutes, which is equal to 25/3 minutes when expressed as an improper fraction.

You had $50. You spent 10% of the money on clothes, 20% on games, and the rest on books. How much was spent inborn books?

Answers

Answer:

$35 was spent on books

Step-by-step explanation:

We must figure out the percent out of $50 that the books are worth

This is 70%

Now we need to figure out how much 10% is out of $50

50 divided by 10

10 percent of the books is 5 dollars

Now to find 20% we do 5+5=10 because it is just x2 of 10%

So we have spent 15 dollars on clothes and games

So now all we must do is 50-15=35

This is how we get our answer!

Pls mark me brainliest! Hope this helps :D

After spending 10% on clothes 20% on games I spent $35 on books.

What is the percentage?

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, You had $50. You spent 10% of the money on clothes, 20% on games, and the rest on books.

Therefore, The expression that represents the context is,

$(50 - (10/100)×50 - (20/100)×50).

= $(50 - 5 - 10).

= $35.

SO, $35 she spent on books.

a 12 foot tall building casts on 8 foot long long shadow. how long of a shadow will a 5 foot tall women have

Answers

This is just a basic proportion. 5/8 = x/12. So the 5 foot tall women would have a 7.5 foot shadow.
Final answer:

Using the concept of similar triangles and the given ratio of a building's height to its shadow, it was calculated that a 5-foot tall woman would cast a shadow that is approximately 3.33 feet long.

Explanation:

The question deals with similar triangles where the ratio of the height of an object to the length of its shadow is constant if the sun's rays are considered to be parallel. Given that a 12-foot tall building casts an 8-foot long shadow, we can use this ratio to determine the length of the shadow that a 5-foot tall woman will cast.

First, find the ratio of the building's height to its shadow's length:

Height of the building / Length of shadow = 12 feet / 8 feet = 1.5

Since the ratio should remain the same, we can set up a proportion for the woman:

Height of the woman / Length of her shadow = 5 feet / x (the unknown length of the shadow)

Now solve for 'x' using cross multiplication:

12 / 8 = 5 / x12*x = 5*8x = (5*8) / 12x = 40 / 12x = 3.33 feet (approximately)

Therefore, the shadow cast by the 5-foot tall woman will be approximately 3.33 feet long.
