The radius of a circle is 10 cm. What is the volume?

Answers

The 3-dimensional shape of a circle is a sphere. In order to solve the volume (v) of a sphere from the radius or diameter of any circumscribed circle within is as follows:
v = 4/3 × pi × r^3, where pi roughly = 3.14
v = 4/3 × 3.14 × (10cm)^3
v = 1.33 × 3.14 × 1000cm^3
v = 4,188.56 cm^3 (cubic cm)
v = 4,189 cm^3 (rounded up)
I believe the answer is 4,188.79

The proof of LN= 16 is shown below:

What is midpoint?

The midpoint formula is applied when one is required to find the exact center point between two defined points. So for a line segment, use this formula to calculate the point that bisects a line segment defined by the two points.

Given:

LM= 8

and M is the midpoint of LN

So, the line LN will be break into two equal parts LM and MN

The area of a rectangular piece of sheet metal is 216 ft. the width of the sheet is 6 ft less than the length what are the dimensions of th epiece of metal

Answers

just multiply lol i think

Using algebra, the dimensions of the rectangular sheet metal with an area of 216 sq ft and width being 6 ft less than the length are found to be 18 ft by 12 ft.

The area of a rectangular piece of sheet metal is given as 216 square feet, and the width is stated to be 6 feet less than the length. Use algebra to find the length (l) and the width (w) of the sheet. Since the width is 6 ft less than the length, we can express this relationship as: w=l- 6.

The area of a rectangle is calculated by the formula Area = length  imes width, so we can set up the equation 216 = l  imes (l - 6). Solving the quadratic equation l^2 - 6l - 216 = 0 we find that the possible values for l are 18 ft (acceptable since length is positive) and -12 ft (which is not physically meaningful for this context), leaving us with the length of the piece of metal being 18 feet. Consequently, the width would be l - 6, which is 18 - 6 = 12 ft.

Therefore, the dimensions of the piece of metal are 18 feet in length and 12 feet in width.

Anna has 10 to the 2nd power quarters. Jazmin has 10 to the second power dimes Who has more money, Anna or Jasmine? How much more? Explain

Answers

Anna has more money... We don't have to do messy calculations for this... Both have 10 to the 2nd power "some amount". 10 to the second power is 100. So they both have 100 coins. 

A quarter is 25 cents, while a dime is only 10 cents. Since they both have the same amounts of coins, the one with 100 quarters has more money, so Anna has more money than Jasmine. 

Now, we need to figure put by how much! 100 quarters is one hundred 25 cent coins. 100*25 = 2500. That is 25 dollars. Whereas, Jasmine has one hundred times 10 cents, which is 1000 cents. This is 10 dollars. 

So, Anna has 15 more dollars than Jasmine. 


This question is based on the concept of logical reasoning.Therefore,they both have the same amounts of coins, the one with 100 quarters has more money.Thus, Anna has more money than Jasmine.

Given:

Anna has 10 to the 2nd power quarters. Jazmin has 10 to the second power dimes.

We need to calculate the who has more money, Anna or Jasmine.

According to the question,

Anna has 10 to the 2nd power quarters.

In mathematically expressed as,

[tex]\bold{10^2 = 100}[/tex] quarters

Now, Jazmin has 10 to the second power dimes.

In mathematically expressed as,

[tex]\bold{10^2 = 100}[/tex] dimes

So,they both have 100 coins. But, we know that quarter is 25 cents, while a dime is only 10 cents.

Anna has 100 quarters =  [tex]\bold{100 \times 25 = 2500}[/tex]. That is 25 dollars.

Jasmine has 100 dimes =    [tex]\bold{100 \times 10 = 1000}[/tex]. This is 10 dollars.

Therefore,they both have the same amounts of coins, the one with 100 quarters has more money.Thus, Anna has more money than Jasmine.

Kendall is stacking boxes that are 7.5inches tall. Explain how to find the height (in inches)

Answers

You can find the height by finding out the number of boxes and plugging it into an equation.  Height = 7.5(Number of Boxes)

Final answer:

To find the height of stacked boxes, multiply the height of one box (7.5 inches) by the total number of boxes stacked.

Explanation:

Kendall is stacking boxes that are each 7.5 inches tall. To find the total height in inches of the stacked boxes, you would need to multiply the height of one box by the total number of boxes stacked. For example, if Kendall stacks 10 boxes, the calculation would be 7.5 inches x 10, which equals 75 inches. Therefore, the total height of the 10 stacked boxes would be 75 inches.

D, open ( and closed ]

Answer:

D. [tex](-\infty,-3]\text{U}(-1,\infty)[/tex]

Step-by-step explanation:

We have been given solution of an inequality on number line. We are asked to write the solution to the given inequality in interval notation.

We can see that all values of x less than or equal [tex]-3[/tex] and greater than  [tex]-1[/tex] are solution for our given inequality.

We have a solid dot at [tex]-3[/tex], so [tex]-3[/tex] is a solution of inequality.

We have a open dot at [tex]-1[/tex], so [tex]-1[/tex] is not a solution of inequality.

Upon combining both solutions, we will get:

[tex](x_2,y_2)=(1,-3)[/tex]

The formula for finding the slope is given by,

You have a rectangular vegetable garden in your backyard that measures 15 feet by 10 feet. You want to double the area of the garden by adding the same distance x to the length and width of the garden. Find the value of x and the new dimensions of the garden.

Answers

Final answer:

To double the area of the rectangular vegetable garden, we need to add the same distance, x, to the length and width. The value of x is 10 feet, and the new dimensions of the garden are 25 feet by 20 feet.

Explanation:

To double the area of the garden, we need to add the same distance, x, to both the length and width of the garden. The original dimensions of the garden are 15 feet by 10 feet, with an area of 150 square feet. To double the area, we set up the equation 2(15+x)(10+x) = 2(15)(10). Solving this equation gives us the value of x and the new dimensions of the garden.

Expanding the equation, we have 30x + x² + 300 = 300. This simplifies to x² + 30x - 300 = 0. Factoring this quadratic equation, we get (x - 10)(x + 30) = 0. So x = -30 or x = 10. We discard the negative value since distance cannot be negative, so x = 10 feet.

The new dimensions of the garden are 15+10 = 25 feet and 10+10 = 20 feet.

A rectangle has one side on the xx-axis and two vertices on the curve y=74+x2. y=74+x2. find the vertices of the rectangle with maximum area.

Answers

Given that a rectangle has one side on the x-axis and two vertices on the curve [tex]y= \frac{7}{4+x^2} [/tex]

We find the vertices of the rectangle with maximum area as follows:

Because of the symmetry of the given curve, the base of the retangle is 2x and the height of the rectangle is y.

Thus, the area of the required rectangle is 2xy where [tex]y= \frac{7}{4+x^2} [/tex]

Thus, [tex]Area=\frac{14x}{4+x^2}[/tex]

For maximum area, we find value of x for which the derivative of the function for the area is equal to zero.

The derivative of the function for the area is given by:

[tex](Area)'= \frac{14(4-x^2)}{(4+x^2)^2} =0 \\ \\ \Rightarrow4-x^2=0 \\ \\ \Rightarrow x^2=4 \\ \\ \Rightarrow x=\sqrt{4}=2[/tex]

Thus, the area is maximum when x = -2 and x = 2

When x = -2,

[tex]y= \frac{7}{4+(-2)^2}= \frac{7}{4+4} = \frac{7}{8} [/tex]

Similarly, when x = 2,

[tex]y= \frac{7}{4+(2)^2}= \frac{7}{4+4} = \frac{7}{8} [/tex]

Therefore, the required vertices are: [tex](-2,0),\ \left(-2, \frac{7}{8} \right), \ \left(2, \frac{7}{8}\right), \ (2, 0)[/tex]
Final answer:

The rectangle with maximum area does not exist as the curve y = 74 + x^2 does not intersect the x-axis.

Explanation:

To find the vertices of the rectangle with maximum area, we need to find the points of intersection between the curve y = 74 + x^2 and the x-axis.

Setting y = 0, we can solve the equation 74 + x^2 = 0 to find the x-coordinates of the vertices.

Since the curve is a parabola facing upwards, there are no points of intersection with the x-axis.

Therefore, the rectangle does not exist.

A master electrician earns $62 per hour. His apprentice earns $40 per hour. The master electrician works 3 hours more than the apprentice. If together they are paid $492, how much does the master electrician earn?
A) $292
B) $312
C) $332
D) $372

Answers

Let x be the number of hours the master electrician works and y the numbers of hours his apprentice works.

The master electrician earns $62 per hour, which means that he earns 62x.
His apprentice earns $40 per hour, which means that he earns 40y.

Together they are paid $492, so we can get the equation:
62x + 40y = 492.

We know that the electrician worked 3 hours more than his apprentice. So he worked x = y + 3 hours. Now let's replace x by its new value in the previous equation.

62x + 40y = 492
62(y+3) + 40y = 492
62y + 186 + 40y = 492

Now we need to put variables apart and numbers apart, so we subtract 186 from both sides of the equation:
62y + 40y + 186 - 186 = 492 - 186
102y = 306

Now we divide both sides by 102
(102y)/102 = 306/102
y = 3

So the apprentice worked 3 hours.
As we already mentioned, the electrician worked 3 hours more than his apprentice.
So he worked x = y + 3 = 3+3 = 6 hours.

The master electrician earns $62 per hour. Since he worked 6 hours, he earns 62 * 6 = 372 dollars.

So the master electrician earns $372 (Option D)
