write 30% as a fraction in its simplest form

Answers

Hello there!

30% would be 0.3 of 1. 

If this would be the case, we would then simplify this into a fraction and make it look like 3/10.

We do this because 30% is .3 of 1, like we already considered, and because of this, 10=1, and 3=30%.

Your answer: 3/10

[tex]\boxed{3/10}[/tex]

Hello there! I can help you! The formula for compound interest is P(1 + r)^t, where P= principal (initial amount), r = interest rate (in decimal form), and t = time (in years). Let's do this step by step. First off, we add the rate into 1. 4% is the interest rate (0.04 in decimal form). 1 + 0.04 is 1.04. Now, what we will do is raise that number to the 2nd power, because the time that elapses is 2 years. 1.04² is 1.0816. That's that. Now, multiply 7,500 to find the total amount of money. 1.0816 * 7,500 is 8,112. There. Toby's savings account balance in 2 years is £8,112.

Note: To solve for compound interest questions like it, add 1 to the percentage rate in decimal form, raise that number to a power based on the number of years (for example, raise the number to the 7th power if we are looking for the balance after 7 years), and then multiply that number by the starting amount. After you raise the number by a power, there may be a lot of numbers behind it. Whatever you do, DO NOT delete the number. Keep it there and multiply it by the principal.

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.

Plz help with this! Thx for the help

Answers

if my math is correct each gallon comes up to about 34 miles travelled, for 544 it would be 16 gallons and for 1 it would be 34, so if you keep adding to this on 7 gallons it will be 238 on 10 it would be 340
102 % 3 is 34 so 1 is 34 and you just tunes the gallons by 34 for the answer so ex(7X34=238) I hope this explanation helps you!

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.

Sarah needs to buy 3 identical shirts to wear. She had $15 gift certificate. Including using the gift certificate, she can spend no more than $80. Which inequality can be used to determine the possible costs for a shirt ?

Answers

Let the cost of a shirt be s.

Three shirts = 3s.

3s + 15 ≤ 80 (Answer F)
Final answer:

The inequality that can be used to determine the possible costs for a shirt is 3x ≤ 65, where x represents the cost of each shirt. Therefore, the possible costs for a shirt must be less than or equal to $21.67.

Explanation:

To determine the possible costs for a shirt, we can use the inequality 3x ≤ 80 - 15,

where x represents the cost of each shirt. The left side of the inequality, 3x, represents the total cost of the 3 shirts. The right side of the inequality, 80 - 15,

represents the amount Sarah has left to spend after using the gift certificate.

Simplifying the inequality, we get 3x ≤ 65.

To find the maximum cost for each shirt, we divide both sides of the inequality by 3, giving us x ≤ 21.67.

Therefore, the possible costs for a shirt must be less than or equal to $21.67.

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:

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


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.

H = 7 ft 10 in = [tex] 7 \frac{10}{12} [/tex] ft
B1 = 10 ft 2 in = [tex]10 \frac{2}{12} [/tex] ft

Rewrite the following equation in slope-intercept form. 17x + 4y = -14 Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

Answer:
y = [tex] \frac{-17}{4} x[/tex] - [tex] \frac{7}{2} [/tex]

Explanation:
The slope-intercept form of an equation has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept

The given is:
17x + 4y = -14

To put this in slope-intercept form,we will need to isolate the y as follows:
17x + 4y = -14
4y = -17x - 14
y = (-17/4)x - (14/4)
y = [tex] \frac{-17}{4} x[/tex] - [tex] \frac{7}{2} [/tex]
where:
m is the slope = -17/4
c is the y-intercept = -7/2

Hope this helps :)

17x+4y = -14
Y= 0
17x = -14
X=-14/17

X=0
4y= -14
Y= -14/4

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.
