The value of x in the equation  (x/7) + 9 = 15 is 42.

To solve for x in the equation (x/7) + 9 = 15, you can follow these steps:

Subtract 9 from both sides of the equation:

(x/7) + 9 - 9 = 15 - 9

(x/7) = 6

Multiply both sides of the equation by 7 to isolate x:

7 × (x/7) = 6 ×7

x = 42

Therefore, the solution to the equation is x = 42.

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:

The formula for the area of a circle is:

Using π as approximately 3.14, we can calculate the area:

Therefore, the area of the playground is about 2826 square feet.

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.

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.

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.

D) y= 3.75x

Step-by-step explanation:

The total cost is y, therefore you set the equation equal to y since you want to find the total cost of candy he purchased.

X is the number of pounds, and the candy is $3.75 each pound.

When you set up the equation, it is

y=3.75x

Which also means: the total cost of the candy depends on how many pounds (which is $3.75 per pound) he buys.

C = 2(3.14)(9.65)

C = 60.602

C = 60.6

Answer:

Archie:  x+20

Betty: 2x-5

Step-by-step explanation:

We are given that The number of cupcakes that  Archie sold can be given as 20 more than a number, x.

So, 20 more than  x = x+20

So, Archie sold cupcakes = x+20

We are also given that Betty  sold five fewer cupcakes than twice a number, x.

So,twice a number, x = 2x

Five fewer cupcakes than twice a number, x. =2x-5

So, Betty sold cupcakes = 2x-5

Hence an algebraic expression that can be used to represent the amount of cupcakes that each senior sold

Archie:  x+20

Betty: 2x-5

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:

72 in^3

Step-by-step explanation:

The volume is found by V=Bh meaning volume = area of the base * height

V = 6 * 12

V = 72

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

). 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

. 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

Final answer:

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.

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

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.
