If the ratio of lemon disinfectant to water is 4 oz to one gallon, then we can say that for each gallon of water, we need 4 oz of lemon disinfectant. To find how much lemon disinfectant is needed for 6 gallons of water, we can multiply the amount needed for one gallon by the number of gallons:

4 oz/gallon * 6 gallons = 24 oz

Therefore, we need 24 oz of lemon disinfectant to be added to 6 gallons of water.

Step-by-step explanation:

Answer:

Given: x * 4 oz = 6 gallons.

First, multiply 4 oz and x:

4x = 6 gallons.

Then convert 6 gallons to oz:

4x = 768 oz.

Step-by-step explanation:

Ratio of female to male : 10:9

Let F be the number of female shoppers and M be the number of male shoppers

That can be expressed as
[tex]\dfrac{F}{M}= \dfrac{10}{9}[/tex]

Given M = 1188

[tex]\dfrac{F}{1188}= \dfrac{10}{9}[/tex]

Multiply both sides by 1188

[tex]\dfrac{F}{1188} \times 1188= \dfrac{10}{9} \times 1188\\\\F = 1,320[/tex]

Total number of shoppers = M + F

The center and radius of the circle with equation (x – 14)2 + (y – 2)2 = 9 is  (14, 2), r = 3, the correct option A.

A circle can be characterized by its center's location and its radius's length.

Let the center of the considered circle be at (h,k) coordinate.

Let the radius of the circle be 'r' units.

Then, the equation of that circle would be:

(x-h)^2 + (y-k)^2 = r^2

We are given that;

The equation of circle=  (x – 14)2 + (y – 2)2 = 9

Now,

We know the equation of a circle with center (h, k) and radius r is:

(x - h)^2 + (y - k)^2 = r^2

Comparing the given equation to this form, we can see that the center of the circle is (14, 2) and the radius is √9 = 3.

The volume of the unused roll is approximately 10,316.97 cubic centimeters.

what is radius ?

A radius is a line segment that connects the center of a circle or a sphere to any point on its circumference or surface, respectively. It is half the length of the diameter, which is a line segment that passes through the center of the circle or sphere and has endpoints on its circumference or surface, respectively. The radius is an important measurement in geometry and is used to calculate other important properties of circles and spheres, such as their area, circumference, and volume.

Given by the question:
To find the area of the base of the cylinder, we need to know the radius. Since the paper towel roll has an inner radius of 4.2 cm and an outer radius of 12 cm, we can calculate the area of the base as follows:

[tex]Area of outer circle - Area of inner circle = πr_outer^2 - πr_inner^2[/tex]

[tex]= \pi (12 cm)^2 - \pi (4.2 cm)^2[/tex]

= [tex]452.16\pi cm^2 - 55.3896\pi cm^2[/tex]

The probability of randomly selecting a number between 1 and 1000 (including both ends) which is divisible by 3, 3 and 5, and 3 or 5 is 33.3%, 6.6%, and 46.7%, respectively.

To find the probability of randomly selecting a number between 1 and 1000 (including both ends), we can count the number of the desired outcomes and divide it by the total number of possible outcomes.

a. To find the probability of randomly selecting a number between 1 and 1000 (including both ends) which is divisible by 3, we can count the number of multiples of 3 between 1 and 1000, and divide by the total number of possible outcomes.

The first multiple of 3 is 3, and the last multiple of 3 that is less than or equal to 1000 is 999.

999/3 = 333

So there are 333 multiples of 3 between 1 and 1000.

probability = 333/1000 = 0.333 = 33.3%

b. To find the probability of randomly selecting a number between 1 and 1000 (including both ends) which is divisible by 3 and 5, we can count the number of multiples of 15 (the least common multiple of 3 and 5) between 1 and 1000, and divide by the total number of possible outcomes.

The first multiple of 15 is 15, and the last multiple of 15 that is less than or equal to 1000 is 990.

990/15 = 66

So there are 66 multiples of 15 between 1 and 1000.

probability = 66/1000 = 0.066 = 6.6%

c. To find the probability of randomly selecting a number between 1 and 1000 (including both ends) which is divisible by 3 or 5, we can count the number of multiples of 3 or 5 (or both) between 1 and 1000, and divide by the total number of possible outcomes.

To count the number of multiples of 3 or 5, we can add the number of multiples of 3 and the number of multiples of 5, and then subtract the number of multiples of 15 (to avoid double-counting).

The number of multiples of 3 between 1 and 1000 is 333, the number of multiples of 5 is 200, and the number of multiples of 15 is 66.

probability = (200 + 333 - 66)/1000 = 0.467 = 46.7%

Hey bro, solving this would be relatively simple. If the Redwood tree is 6 meters tall, then the height of the carpool lane sign can be easily calculated using similar triangles. Using the lengths of their respective shadows, the carpool lane sign should be 3 meters tall, because the ratio between the height of the Redwood tree and the carpool lane sign, is the same ratio as between their respective shadows (8 to 4). The based way to solve this problem would be to measure the length of the shadows, and then use the ratio to calculate the height of the carpool lane sign.

Answer:

You need to set up the problem to solve for X. X = how tall is the tree? Set up your problem in this fashion. Set up the formula then arrange to solve for X. X/9 (shadow of the tree) = 15 (how tall the building is)/6 (shadow of building) X= 15/6 * 9 To get X alone, you need to move 9 to the other side of the equation. multiply by 9 on each side. For X side, this nullifies 9 and gets 9 to the other side. X= 2.5*9 You have divided 15 by 6, now multiply by 9 to get final answer for X X=22.5 meters The tree is 22.5 meters tall.

The x-intercept is (2, 0) and the y-intercept is (0, -2).

An intercept in mathematics is a location on the y-axis through which the line's slope passes. It is a place on the y-axis where a straight line or a curve crosses. This is reflected in the equation for a line, which is written as y = mx+c, where m denotes slope and c denotes the y-intercept.

We have the Equation: 4−2y=8−2x

To find the x-intercept, we set y = 0

4 - 2(0) = 8- 2x

4 = 8 -2x

2x = 8-4

2x = 4

x = 2

The statement that corresponds to a probability of an event occurring is the probability mass of observing 50 successes in 50 binomial trials.

Probability represents comprehensive analysis of the reasonable likelihood that a particular outcome shall typically occur. This occurrence is dependent on the ratio of favorable instances to probable instances. The integral of the chi-squared distribution's density among complex chi-squared values of zero and five and probability density of the chi-squared distribution at chi-squared value four are functionally related to the overall chi-squared distribution. However, neither of them directly reflects the likelihood that an event will actually take place.

Let's call the amount of water in the first pool "x" and the amount of water in the second pool "y". We know that:x = 582 + 20.25t (where t is the time in minutes)

y = 44.5tWe want to find the time "t" at which x = y, so we can set the two equations equal to each other:582 + 20.25t = 44.5t

Expanding the second equation and solving for t, we get:582 = 24.25t

t = 582 ÷ 24.25 = 24 minutes

So, after 24 minutes, the two pools will have the same amount of water.

To find out how much water will be in each pool, we can plug this value of t back into the first equation:x = 582 + 20.25t = 582 + 20.25(24) = 582 + 485 = 1067 liters

y = 44.5t = 44.5(24) = 1067 liters

So, both pools will contain 1067 liters of water.

Answer:

Below

Step-by-step explanation:

First pool starts with 582 and adds  20.25 * m        m = minutes

Volume1 = 582 + 20.25 m

Volume 2 = 44.5 m

At what 'm' are they equal ?

582 + 20.25 m       =      44.5 m       subtract 20.25 m from both sides to get

582 = 24.25 m       divide both sides of the equation by 24.25

m = 24 minutes      <=====use this value in either equation to find the volume          volume2 = 44.5 * 24 = 1060 gallons

A central angle of circle P is angle TPQ.

The measure of RU is 59 degrees.

In Geometry, an arc can be defined as a trajectory that is generally formed when the distance from a given point has a fixed numerical value. Generally speaking, the degree measure of an arc in a circle is always equal to the central angle that is present in the included arc.

Based on the information provided about Circle P, we can logically deduce that m∠TPU and m∠UPR are supplementary angles:

m∠TPU + m∠UPR = 180°

m∠TPU = 180° - 59°

m∠TPU = 121°.

m∠TPQ + m∠QPR = 180°

m∠QPR = 180° - 107°

m∠QPR = 73°.

2. If you continue paying at the rate above (assuming there is no additional interest), it will take 38 months for you to pay off the credit card balance.

An equation is a mathematical statement showing the equality of two or more mathematical expressions using the equation symbol (=).

The total debt on the credit card = $8,500

The promotional interest rate for 24 months = 0%

Monthly repayment = $170

Total repayment after 12 months = $2,040 ($170 x 12)

Balance on the credit card after 12 months of repayment = $6,460 ($8,500 - $2,040)

The number of months to repay the balance without interest = 38 months ($6,460/$170).

Three equal payments of $1,468834.26 made today, in month 10, and in month 15, with 5% semiannual interest, will be sufficient to cover the debt of $4,000,000 that matures in month 7.

To replace the obligation of $4,000,000 that matures in month 7, we need to calculate the size of three equal payments that can be made today, in month 10, and in month 15, that will cover the debt with interest.

First, we need to determine the semiannual interest rate. The annual interest rate is 10%, so the semiannual interest rate is 5% (10%/2).

Next, we can use the present value formula to calculate the size of the equal payments:

PV = PMT * [(1 - (1 + r)^-n) / r]

where PV is the present value of the debt, PMT is the size of the equal payments, r is the semiannual interest rate, and n is the number of semiannual periods.

Since the debt matures in month 7, which is the end of the sixth month, and the payments will be made today (month 0), in month 10 (the end of the ninth month), and in month 15 (the end of the fourteenth month), we have three semiannual periods to consider.

Using the values we have, we can substitute them into the formula:

PV = $4,000,000

r = 5%

n = 3

$4,000,000 = PMT * [(1 - (1 + 5%)^-3) / 5%]

Answer:

The correct answer is C) The scale factor is multiplied by the scale figure's lengths.

When using a scale factor, you are typically working with a "scale figure," which is a smaller or larger version of the original figure. To determine the lengths of the original figure using a scale factor of 0.25, you would multiply each length of the scale figure by 0.25.

For example, if the scale figure has a length of 8 units, you would multiply 8 by 0.25 to get 2, which would be the corresponding length of the original figure. So if the original figure was four times larger than the scale figure, it would have a length of 32 units (4 times 8).

Therefore, when using a scale factor to determine the lengths of an original figure, you need to multiply each length of the scale figure by the scale factor to get the corresponding length of the original figure.
