Answer:

263.76

Step-by-step explanation:

To answer this question, we need to know the equation for surface area of a cylinder which can be given as Surface Area=2*pi*[tex]R^{2}[/tex]+2*pi*R*H, where R is the radius of the cylinder (also can be calculated as Diameter/2=6/2=3) and H is the height of the cylinder which is given as 11. Considering pi=3.14, the surface area of the cylinder can now be calculated as 2*3.14*[tex]3^{2}[/tex]+2*3.14*3*11=263.76.

Answer:

x=-7

x=7

Step-by-step explanation:

we have

[tex]2x^{2}-98=0[/tex]

Solve for x

Adds 98 both sides

[tex]2x^{2}-98+98=0+98[/tex]

[tex]2x^{2}=98[/tex]

Divide by 2 both sides

[tex]2x^{2}/2=98/2[/tex]

[tex]x^{2}=49[/tex]

take square root both sides

[tex]x=\pm7[/tex]

therefore

The solutions are

x=-7

x=7

Answer:

-3/4

Step-by-step explanation:

The least common denominator is 8.

So you make -3/4 into -6/8 by multiplying 2 in the numerator and denominator.

Now just compare them -6/8 compared to -7/8

-6/8 is bigger since it is closer to 0 (since we are dealing with negative numbers.)

Have a great day!

The cost of one book is $6.

Step-by-step explanation:

Given,

Lizzie paid for 8 books = $50 bill

Alex paid for 3 books = $20 bill

As the both received same change.

Let,

x represent cost of one book.

y represent the change received.

According to given statement;

50-8x=y    Eqn 1

20-3x=y    Eqn 2

Putting value of y from Eqn 1 in Eqn 2

[tex]20-3x=50-8x\\-3x+8x=50-20\\5x=30[/tex]

Dividing both sides by 5

[tex]\frac{5x}{5}=\frac{30}{5}\\x=6[/tex]

The cost of one book is $6.

Radian measure of the central angle is 4 radian

Solution:

Given that,

A circle of radius 1.5 meter that intercepts an arc of length 600 centimeters

To find: Radian measure of the central angle

Let us find the circumference of circle

The circumference of circle is given as:

[tex]\text{ circumference of circle } = 2 \pi r[/tex]

Where "r" is the radius of circle

[tex]\text{ circumference of circle } = 2 \times \pi \times 1.5 = 3 \pi[/tex]

Therefore circumference of circle = [tex]3 \pi[/tex] meters , which subtends central angle of  [tex]2 \pi[/tex] radian

Given that arc of length 600 centimeters. Let us convert 600 centimeter to meter

We know that, to convert centimeter to meter divide the length value by 100

[tex]\text{ 600 centimeter } = \frac{600}{100} \text{ meter } = 6 \text{ meter}[/tex]

Therefore arc of 6 meter will subtend a central angle of:

[tex]\rightarrow \frac{6}{3 \pi} \times 2 \pi = 4[/tex]

Therefore radian measure of the central angle is 4 radian

Answer & Explanation:

To determine the age of a tree, first find its diameter by measuring the circumference of the trunk in inches and then dividing that number by pi. Once you have the tree's diameter, look up the growth factor for the type of tree you're measuring, which is how much width it gains annually.

The height and diameter of a tree is a function of its age.

Growth rate of a system is defined as the rate at which the system grows by length, breadth, height, etc.

Here,

The growth rate of a tree represents the age of the tree. The measurement of the height and diameter of the tree is used to calculate the age of the tree. These measurements of height and radius of the tree can be considered as a function of its age.

The method of calculating the age of the tree is,

The circumference at a height above 4.5 feet from the ground is measured(breast height).

Dividing the circumference at breast height with pi(3.14), thus we get the diameter at breast height.

Multiplying the diameter with growth factor will give the age of the tree in years.

Hence,

The height and diameter of a tree is a function of its age.

Answer:

At 9pm Greta and Marge have collected the same amount  of money.

Step-by-step explanation:

Consider the provided information.

Let x represents the number of hours Greta and Marge are both collecting.

It is given that  Greta had already collected $45.00 till 11 am.

Greta = 45 + 15x

Marge collects money at a rate of $20 per hour.

Marge = 20x

Greta and Marge have collected the same amount  of money.

Thus,​

45 + 15x = 20x

45 = 5x

9 = x

Hence, once Marge starts collecting, it would take 9 hours to collect same amount of money.

9 hours after 11am is 8pm. It is given that there is a break time of 1 hour

Hence, at 9pm Greta and Marge have collected the same amount  of money.

Final answer:

The units digit is 0, the hundreds digit is 4, and the tens digit is 8, making the 3-digit number 480.

Explanation:

The question involves finding a 3-digit number where the hundreds digit is four more than the units digit, the tens digit is twice the hundreds digit, and the sum of the digits is 12. To solve this, we can use algebra.

Let's designate the units digit as 'u'. According to the problem, the hundreds digit will then be 'u + 4'. The tens digit is twice the hundreds digit, which gives us '2(u + 4) = 2u + 8'. Now we can use the information that the sum of the digits equals 12 to create the equation: u + (u + 4) + (2u + 8) = 12.

Simplifying this equation, we get: 4u + 12 = 12, which further reduces to 4u = 0. This indicates that u, the units digit, is 0. Thus, the hundreds digit is 0 + 4 = 4 and the tens digit is 2×4 = 8.

The 3-digit number we are looking for is therefore 480.

Hey there!

To find the slope of the two points that you were given, use the slope formula:

[tex]\frac{y2-y1}{x2-x1}[/tex]

y2 is the y value of the second point pair, y1 is the y value of the first point pair, x2 is the x value of the second point pair, and x1 is the x value of the first point pair.

Now, plug in your values:

y2= 9

y1= 6

x2= 6

x1= 3

[tex]\frac{9-6}{6-3}[/tex] = [tex]\frac{3}{3}[/tex] = 1

Therefore, the slope of the two points is 1.

Answer:

All the right triangles will be similar.

Step-by-step explanation:

See the attached diagram.

Let us assume any two right triangles are drawn on the line OP, and AB and A'B' as the hypotenuse on the same line OP.

Since the slope of the line OP is constant and assume that it makes x° with the positive x-axis.

Hence, [tex]\tan x = \frac{AC}{BC} = \frac{A'C'}{B'C'}[/tex]

⇒ [tex]\frac{AC}{A'C'} = \frac{BC}{B'C'}[/tex]

Therefore, the sides of the two right triangles are in the same ratio and hence, Δ ABC and Δ A'B'C' are similar.

Hence, all the right triangles will be similar. (Answer)

r=1

To find the missing coordinate “r” given two points on a line and the slope, we can use the slope formula. Using the given slope and the coordinates of the points, we can set up an equation to solve for the missing value of “r”. By solving the equation, we find “r” is equal to 1.

To find the missing coordinate r, we can use the slope formula. The slope m is given as 3/4, and the coordinates of the two points are (3, -2) and (7, r).

We can use the formula: m = (y2 - y1) / (x2 - x1) to find the missing value of r. Substituting the values, we have:

3/4 = (r - (-2)) / (7 - 3)

Solving for r:

3/4 = (r + 2) / 4

Multiplying both sides by 4:

3 = r + 2

Subtracting 2 from both sides:

r = 1

Answer: 1,350 hats

Step-by-step explanation: First, it's important to understand that 50% is equivalent to the fraction 1/2.

So, the next year that hat store will sell 1/2 more hats.

First, we need to divide 900 by 2 which gives us 450.

Now, we simply add 450 to to the number of hats the store sold the first year.

450 + 900 = 1,350

This means that the hat store will sell 1,350 hats the next year.

Given

2x³ + 10x² - 4x²y - 20xy ← factor out 2x from each term

= 2x(x² + 5x - 2xy - 10y)

Factor the first/second and third/fourth terms inside the parenthesis

= 2x(x(x + 5) - 2y(x + 5)) ← factor out (x + 5) from each term in the parenthesis

= 2x(x + 5)(x - 2y)

Answer: [tex]6.9\ minutes[/tex]

Step-by-step explanation:

Let "x" represents the 16% of 43 minutes.

Once you analize the information given in the exercise, you can identify that 43 minutes is the 100%.

Then, with this data, you can set up the following proportion:

[tex]\frac{100}{43}=\frac{16}{x}[/tex]

Now you must solve for "x". The steps are:

- Multiply both sides of the equation by "x"

 [tex](x)(\frac{100}{43})=(\frac{16}{x})(x)\\\\\frac{100x}{43}=16[/tex]

- Multiply both sides by 43:

[tex](43)(\frac{100x}{43})=(16)(43)\\\\100x=688[/tex]

- Divide both sides by 100:

[tex]\frac{100x}{100}=\frac{688}{100}\\\\x=6.88[/tex]

- Rounding to the tenths place:

[tex]x\approx6.9[/tex]
