The inequality to determine the minimum amount each cheerleader needs to raise to cover the team fee and individual entry fees is m >= $50.99. This is calculated by dividing the team fee of $99 and the total individual fees of $818.82 by 18 cheerleaders, and summing those amounts.
Explanation:
The question asks to find an inequality to determine the minimum amount of money, m, each cheerleader needs to raise to cover both the team fee and individual fees. Coach Walker's cheerleading team has a total team fee of $99 and individual fees amounting to $818.82 for 18 cheerleaders.
To find the equation that expresses the total cost, we start with the total individual fee for the cheerleaders, which is $818.82. This fee needs to be divided among the 18 cheerleaders, and when added to the team fee that is split equally, it gives the amount each cheerleader should raise.
The inequality should ensure that the total amount raised by each cheerleader, m, is enough to cover both their share of the team fee and their individual fee. The equation for the team fee per cheerleader is $99 divided by 18. We can add the individual fee of $818.82 divided by 18 to this amount to find the minimum amount each cheerleader should raise.
Setting up the Inequality
First, calculate the per person cost for the team fee: $99 / 18 = $5.50 per cheerleader.
Second, calculate the per person individual fee cost: $818.82 / 18 = $45.49 per cheerleader.
Now, we add both of these to find the total minimum amount each cheerleader should raise: $5.50 (team fee per cheerleader) + $45.49 (individual fee per cheerleader) = $50.99.
The inequality that represents the minimum amount each cheerleader needs to raise is:
m >= $50.99
This inequality ensures that each cheerleader raises at least enough to cover their portion of the fees.

The volume of this cone is 932.58 cubic meters. What is the height of this cone?
The height of the cone is approximately 9 meters.
The formula for the volume (V) of a cone is given by:
[tex]\[ V = \frac{1}{3} \pi r^2 h \][/tex]
where r is the radius of the base and h is the height.
Given that the volume V is 932.58 cubic meters, we can rearrange the formula to solve for h:
[tex]\[ h = \frac{3V}{\pi r^2} \][/tex]
Since the problem doesn't provide the radius r, we cannot calculate the exact height. However, if the cone is assumed to have a radius of 1 meter (as it's not provided), you can substitute the values into the formula:
[tex]\[ h = \frac{3 \times 932.58}{3.14 \times 1^2} \][/tex]
Simplifying this gives:
[tex]\[ h \approx 9 \, \text{meters} \][/tex]
Therefore, under the assumption of a radius of 1 meter, the height of the cone is approximately 9 meters.

To multiply powers with the same base, like (4^6)(4^-8), add the exponents to get 4^(6-8) = 4^-2. Converting the negative exponents gives us 1/4^2 or 1/16 as the simplified expression.
Explanation:To rewrite the expression in the form 4n4n, we use the rule that when multiplying two numbers with the same base, we add their exponents. So, (46)(4-8) = 4(6 + (-8)) = 4-2 = 1/42 = 1/16.
When multiplying powers with the same base, you simply add the exponents. In the expression (4^{6})(4^{-8}), we add the exponents 6 and -8. The rules of exponents tell us that 4^{6} \times 4^{-8} = 4^{6-8} = 4^{-2}. Negative exponents indicate the reciprocal of the base raised to the positive of that exponent. Therefore, 4^{-2} = \frac{1}{4^{2}} = \frac{1}{16}. This simplified expression demonstrates how to work with exponents and manage negative exponents effectively.

Answer: D
Step-by-step explanation: the temperature changes from 92° to 43°
so 92 - 43 = 49 meaning that the temperature changed 49 degrees in total and if it changed the same amount in the seven days you have to divide 49 by 7 = 7
C is wrong since it did change by 7 but the option to decrease is there and the temperature didn't increase or get warmer but instead decreased or became cooler so it is D

product of (2x+3)(2x+4)
Answer:
4x² + 14x + 12
Step-by-step explanation:
There are several different methods you can use to multiply binomials, but I will walk through the FOIL method.
First - Multiply the first terms of each binomial
2x · 2x
Outer - Multiply the outside terms of each binomial (the first term of the first binomial and the second term of the second binomial)
2x · 4
Inner - Multiply the inside terms of each binomial (the second term of the first binomial and the first term of the second binomial)
3 · 2x
Last - Multiply the last term of each binomial
3 · 4
Then you will add each product together to get the expression 4x² + 8x + 6x + 12. This is not our answer as we have to combine like terms to simplify.
After simplifying, 4x² + 14x + 12 will be the answer.
If the diameter of a circle is 19.3, what is the circumference?
Answer:
60.6
Step-by-step explanation:
The formula for finding the circumference of a circle is C = 2πr
C is circumference, π is pi (we'll just us 3.14 here), and r is radius.
The radius is found by dividing the diameter in half.
19.3/2=9.65
So the equation should look like this:
C = 2(3.14)(9.65)
C = 60.602
C = 60.6

Topic: Volume
Answer: V = 0.6 m.
Step-by-step explanation:
Volume = l x w x h
in this case if you input the cube's values its volume = 1 m and 1 - 0.4 = 0.6m
Volume is a measure of how much space something takes up and is usually measured in cubic centimetres ({cm}^3cm
3
) or cubic metres ({m}^3m
3
). Density is a measure of how tightly the mass of an object is packed into the space it takes up, so we calculate this by dividing its mass by its volume.
{density } = \dfrac{{mass}}{{volume}}density =
volume
mass
As a result, the units we used to measure density are compound units for more information, see here . The unit of choice will depend on what units are used to measure the values you’re given. If, in a particular question, mass is measured in kilograms and volume is measured cubic metres, then the density we calculate would be measured “kilograms per cubic metre”, which is denoted either by {kgm}^{-3}kgm
−3
or kg/m}^3kg/m
3
. If the starting units were different, then the resulting unit of density would be different. Let’s see an example.
Example: An object has a mass of 570g and a volume of 2,280 cm}^3cm
3
. Calculate its density.
As stated, density is equal to the mass divided by the volume, so this will be our calculation, but what will the unit of our answer be? In the question, the mass is given in grams and the volume in cubic centimetres, so the density should be in grams per cubic metre, which is denoted either like \{gm}^{-3}gm
−3
or {g/m}^3g/m

The linear correlation coefficient r is **1.2237445080439002**.
To calculate the linear correlation coefficient r, we can use the following formula:
[tex]r = (\sum(x - \bar x)(y - \bar y)) / \sqrt(\sum(x - \bar x)^2 \sum(y - \bar y)^2)[/tex]
where:
* [tex]\sum[/tex] is the sum of the values
* [tex]\bar x[/tex] is the mean of x
* [tex]\bar y[/tex] is the mean of y
First, we need to calculate the mean of x and y:
[tex]\bar x[/tex] = (4 + 53 + 86 + 162) / 4 = 71.25
[tex]\bar y[/tex] = (-5 - 1 + 13 + 16) / 4 = 5.75
Next, we need to calculate the sum of the squared deviations from the mean for x and y:
[tex]\sum(x - \bar x)^2 = (47.25^2 + 17.25^2 + 14.25^2 + 90.75^2) = 10148.5[/tex]
[tex]\sum(y - \bar y)^2 = (11.25^2 + 6.75^2 + 7.25^2 + 10.25^2) = 317.5[/tex]
Now, we can calculate the linear correlation coefficient r:
[tex]r = (\sum(x - \bar x)(y - \bar y)) / \sqrt(\sum(x - \bar x)^2 \sum(y - \bar y)^2)[/tex]
r = (47.25 * 11.25 + 17.25 * 6.75 + 14.25 * 7.25 + 90.75 * 10.25) / √(10148.5 * 317.5)
r = 1.2237445080439002
Therefore, the linear correlation coefficient r is **1.2237445080439002**.
This value indicates a strong positive correlation between x and y.

Answer:
i think its 180
Step-by-step explanation:
u have to multiply 60 and 3 and u will get 180
The area of a circular playground with a diameter of 60 feet is calculated using the formula Area = π × radius². With a radius of 30 feet, the area is approximately 2826 square feet. Therefore, the area of the playground is about 2826 square feet.
To find the area of a circular playground, we first need to know its radius. Since the diameter of the playground is given as 60 feet, the radius (which is half the diameter) is:
Radius = Diameter / 2 = 60 feet / 2 = 30 feetThe formula for the area of a circle is:
Area = π × radius²Using π as approximately 3.14, we can calculate the area:
Area = 3.14 × 302 = 3.14 × 900 = 2826 square feetTherefore, the area of the playground is about 2826 square feet.

Which equations have the same value of x as Three-fifths (30 x minus 15) = 72? Select three options. 18 x minus 15 = 72 50 x minus 25 = 72 18 x minus 9 = 72 3 (6 x minus 3) = 72 x = 4.5
Answer:
C.
D.
E.
Step-by-step explanation:
The two options that yield the same value for 'x' as the equation 'Three-fifths (30 x minus 15) = 72' are '3 (6 x minus 3) = 72' and 'x = 4.5'. The confusion can be eliminated by simply breaking down and solving the initial equation for 'x', and then substituting the calculated value for 'x' into the optional equations.
Explanation:To discover which options yield the same value as 'Three-fifths (30 x minus 15) = 72', we first need to solve the given equation for 'x'. This can be done as follows:
Multiply both sides by 5/3 to get rid of the 3/5 in front of the bracket: (30 x minus 15) = 120,Add 15 to both sides to isolate 30x on the left side: 30x = 135,Finally, divide by 30: x = 4.5.Substitute x = 4.5 into each option:
For '18 x minus 15 = 72', 18(4.5) - 15 isn’t equal to 72, so this is not correct.For '50 x minus 25 = 72', 50(4.5) - 25 isn’t equal to 72, so this isn’t correct as well.For '18 x minus 9 = 72', 18(4.5) - 9 isn’t equal to 72 either, hence, it is also incorrect.For '3 (6 x minus 3) = 72', 3(6*4.5 - 3) equals to 72, so this is correct.For 'x = 4.5', this is obviously correct as it matches our calculated value.Therefore, '3 (6 x minus 3) = 72' and 'x = 4.5' provide the same value for x as the initial equation 'Three-fifths (30 x minus 15) = 72'.

To find the number of cheerleading groups that can be made with 22 fourth-graders and 26 fifth-graders, we add the total number of students and divide by the group size (8). The equation is k = (22 + 26) / 8, which simplifies to k = 6, meaning 6 groups can be formed.
Explanation:
The question is asking how to calculate the total number of cheerleading groups that can be formed from a given number of fourth-grade and fifth-grade students. In this case, there are 22 fourth-grade students and 26 fifth-grade students, making a total of 48 students. Given that each group should have 8 members, the formula to find the number of groups is the total number of students divided by the number of members per group.
The equation to find the number of cheerleading groups (k) is:
k = Total number of students / Number of members per group
Thus, the equation is:
k = (22 + 26) / 8
When simplified, it gives:
k = 48 / 8
Which equals:
k = 6
Therefore, 6 cheerleading groups can be made.

What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
We have to given that;
A cylinder has surface area of 256 π square millimeters and a height of 8 millimeters.
Since, We know that;
Surface area of cylinder is,
SA = 2πrh + 2πr²
Here, We have;
SA = 256π
h = 8 mm
Hence, We get;
256π = 2π × r × 8 + 2π × r²
128 = 8r + r²
r² + 8r - 128 = 0
r² + 16r - 8r - 128 = 0
r (r + 16) - 8 (r + 16) = 0
(r - 8) (r + 16) = 0
r = 8 mm

Samuel earned 18.90 working last weekend. He worked for 2 and 1 fourth hours. Which equation and solution represents e, the amount Samuel earns each houre at his job
Answer:
The equation that represents the amount Samuel earns per hour is "e = (total earned)/(total time worked)", on last weekend he earned 8.4 per hour.
Step-by-step explanation:
Since Samuel worked a total of 2 and 1/4 hours it means that he worked:
hours worked = 2 + 1/4
hours worked = 8/4 + 1/4
hours worked = 9/4
He earned a total of 18.9 working that many hours. If we divide the total amount he earned by the number of worked hours we can find the total he earns per hour.
e = (total earned)/(total time worked)
e = 18.9/(9/4)
e = 18.9*(4/9)
e = 75.6/9
e = 8.4 per hour
The equation that represents the amount Samuel earns per hour is "e = (total earned)/(total time worked)", on last weekend he earned 8.4 per hour.
