Answer:

volume = 4/3 × pi × r^3

Step-by-step explanation:

Answer:

Calculate the area of the base (which is a circle) by using the equation πr² where r is the radius of the circle. Then, multiply the area of the base by the height of the cylinder to find the volume.

Circumference   =   2 • π • radius   =   π • diameter

Circle Area   =       π • r²     =     ¼ • π • d²

The circumference of a circle is directly proportional to its radius. The ratio between a circle's circumference and its diameter is pi, a constant that equals approximately 3.142. The circle's diameter, in turn equals twice the radius. A regular solid that has a circle as a face is called a cylinder. Like all geometric prisms, a cylinder's volume is the product of its cross-sectional area and its length. The cross-sectional area is the area of its circle, and you can calculate it from the circle's radius. Multiply the circle's radius by 2 to calculate its diameter. For instance, if the radius equals 6 inches, compute as follows to determine the diameter: 6 x 2 = 12 inches. Multiply the diameter by pi to get the circle's circumference: 12 x 3.142 = approximately 37.7 inches. Find the square of the radius: 6 x 6 = 36 square inches. Multiply the answer determined in Step 3 by pi to get the circle's area: 36 x pi = 113 square inches. Multiply the circle's area by the cylinder's length to obtain the volume. If the length is, for instance, 10 inches, then compute as follows: 113 x 10 = 1,130 cubic inches.

The equation best represents x, the amount of money Mr. Schultz needs to save to buy the shoes is 75+x=200

Step-by-step explanation:

Mr. Schultz was given amount on his birthday = $75

We are given that Mr. Schultz needs $200 to buy some new Jordan shoes.

Let x be the amount of money Mr. Schultz needs to save to buy the shoes

So, Total Amount saved = 75+x

Total cost of shoes = $200

So, 75+x=200

So, The required equation is 75+x=200

So, Option A is true

Hence The equation best represents x, the amount of money Mr. Schultz needs to save to buy the shoes is 75+x=200

Answer:

-(4,2)

Step-by-step explanation:

Answer:

We can make an equation

2 * 7x + 2 * 4x + 2 * 4 * 7 = 298

14x + 8x + 56 = 298

22x = 298 - 56

22x = 242

x = 242/22

x = 11

If the surface area of the prism is 298 square feet, the value of x is 11 feet.

To find the value of x, we need to use the formula for the surface area of a rectangular prism:

Surface Area (SA) = 2lw + 2lh + 2wh,

where l is the length, w is the width, and h is the height of the prism.

Given that the length (l) is 7 ft and the width (w) is 4 ft, and the surface area (SA) is 298 square feet, we can set up the equation:

298 = 2(7)(x) + 2(7)(4) + 2(4)(x).

Now, simplify the equation:

298 = 14x + 56 + 8x.

Combine like terms:

298 = 22x + 56.

Now, isolate x by moving the constant term to the other side of the equation:

22x = 298 - 56,

22x = 242.

Finally, solve for x:

x = 242 / 22,

x = 11.

In summary, the height of the rectangular prism is 11 feet, and this value is obtained by using the surface area formula and solving the resulting equation.

Answer:

The percentage increase is 44.44%

What best describes the error is that the denominator should be 18 which is the original amount

Step-by-step explanation:

Here, we are to calculate the percentage increase from 18 to 26

Mathematically, we can calculate this with the following formula;

(New value - old value)/old value * 100%

Where the new value is 26 and the old value is 18. Plugging these values, we have;

(26-18)/18 * 100%

8/18 * 100% = 44.44% increase

The error in finding the percent increase from 18 to 26 is, The numerator should be 18, which is the original amount.

The percentage increase from 18 to 26 is about 44.4%.

We have to give that,

To find the percent increase from 18 to 26.

Now, The process to find a percent increase from 18 to 26 is,

(26 - 18) / 18 x 100%

= 8/18 x 100%

= 800/18%

= 44.4%

Answer:

x = 3.431

Step-by-step explanation:

Given equation is,

[tex]5^{(3x-9)}-10=-2[/tex]

[tex]5^{3x-9}-10+10=-2+10[/tex]

[tex]5^{3x-9}=8[/tex]

By taking log on both the sides of the equation,

[tex]\text{log}(5^{3x-9})=\text{log}8[/tex]

(3x - 9)log5 = log8

3x - 9 = [tex]\frac{\text{log}8}{\text{log}5}[/tex]

3x - 9 = 1.292

3x = 9 + 1.292

x = [tex]\frac{10.29202}{3}[/tex]

Answer:

Town  "A" was going to have a larger population eventually

Town "A" = 3458 inhabitants

Town "B" = 2600 inhabitants

Step-by-step explanation:

Eventually Town  "A" will have a greater population population because it increases in percentage with respect to each year, therefore, there will come a time that its increase will be greater than 50 per year, which is what Town "B" increases.

To calculate the population the first thing is to know that 30 years have passed, then we must calculate that 30-year increase.

For Town "A" the increase would be as follows:

800 * (1.05 ^ 30) = 3457.55 = 3458 inhabitants

For Town "B" the increase would be as follows:

1100 + 50 * 30 = 2600 inhabitants

Thus checking that Town  "A" was going to have a larger population eventually
