.
Reset

Answers

Answer 1

Answer:

(x-5)^2+(y+4)^2=100

Step-by-step explanation:

As we know the given points

Center = (5, -4)

and

Point on circle = (-3,2)

The distance between point on circle and center will give us the radius of circle

So,

The formula for distance is:

[tex]\sqrt{(x_{2}-x_{1} )^{2}+(y_{2}-y_{1})^{2}}\\Taking\ center\ as\ point\ 1\ and\ the\ other\ point\ as\ point\ 2\\d=\sqrt{(-3-5)^{2}+(2-(-4))^{2}}\\d=\sqrt{(-8)^{2}+(2+4)^{2}}\\d=\sqrt{(-8)^{2}+(6)^{2}}\\\\d=\sqrt{64+36}\\d=\sqrt{100} \\ d=10\\So\ the\ radius\ is\ 10[/tex]

The standard form of equation of circle is:

[tex](x-h)^{2}+(y-k)^{2}=r^{2}[/tex]

where h and k are the coordinates of the center. So putting in the value:

[tex](x-5)^{2}+(y-(-4))^{2}=(10)^{2}\\(x-5)^{2}+(y+4)^{2}=100[/tex]

Two cylinders. The smaller cylinder has height labeled as 1 cm. The larger cylinder has height labeled as 3 cm.

The cylinders are similar. The volume of the larger cylinder is 2106 cubic centimeters. What is the volume of the smaller cylinder?



93 cm3


81 cm3


78 cm3


65 cm3

Answers

Answer: third option.

Step-by-step explanation:

You know that the height of the smaller cylinder is 1 cm and the height of the  larger cylinder is 3 cm, then you can find the volume ratio. This  is:

[tex]Volume\ ratio=(\frac{1\ cm}{3\ cm})^3\\\\Volume\ ratio=\frac{1}{27}[/tex]

Knowing that the volume of the larger cylinder is 2,106 cubic centimeters, you need to multiply it by the volume ratio to find the volume of the smaller cylinder.

Therefore:

[tex]V_{smaller}=\frac{1}{27}(2,106\ cm^3)\\\\V_{smaller}=78\ cm^3[/tex]

ANSWER

The correct answer is C

EXPLANATION

We have that, the smaller cylinder has height 1 cm and the larger cylinder has height 3cm.

The scale factor of similarity is

[tex]k = \frac{1}{3} [/tex]

That's if the smaller cylinder is the image.

The volume of the larger cylinder is 2106 cm³.

To find the volume of the smaller cylinder, we multiply the volume of the larger cylinder by k³

[tex]( { \frac{1}{3} })^{3} \times 2106 {cm}^{3} [/tex]

[tex]{ \frac{1}{27} } \times 2106 = 78 {cm}^{3} [/tex]

Part A: Eveline rented a car at $180 for 4 days. If she rents the same car for 9 days, she has to pay a total rent of $325.

Write an equation in the standard form to represent the total rent (y) that Eveline has to pay for renting the car for x days.

Part B: Write the equation obtained in Part A using function notation.

Part C: Describe the steps to graph the equation obtained above on the coordinate axes. Mention the labels on the axes and the intervals.

Answers

Answer:

Step-by-step explanation:

There is a standard cost just for renting the car.

Let the daily cost = x

Let the addon be = z The add on is the amount they charge just to give you the keys and do the paper work. It might include insurance.

y = z + 4x

y = 180

z = ??

x = 4

y = 325

z = ??

x = 9

Equation 1: 180 = z + 4x

Equation 2:325 = z + 9x

Subtract (1) from (2)

325 = z + 9x

180 = z + 4x                         Subract

145 = 5x                               Divide by 5

145/5 = 5x/5

x = 29

What you have found is the daily cost. Now you have to find the fixed cost.

y = 29x + z

180 = 29*4 + z

180 = 116 + z                  Subtract 116 from both sides

180 - 116 = z

z = 64

Answer: Part A

y = 29x + 64

Part B

f(x) = 29x + 64

Part C

So what are the intervals?

Horizontally: each square is worth.

Lilly and Laura pooled their money to purchase
their brother, Liam, a video game for his birthday.
The video game cost a total of $45. If Laura was
only able to contribute of what Lilly did, how
much did Laura put toward the present?​

Answers

Answer: $22.50

Step-by-step explanation: let x represent the amount Laura and Lilly contributed each. If Laura and Lilly contributed the same amount, x+x=2x=45. If 2x=45, divide both sides by 2 to find the value of x. 45/2= 22.5.

Final answer:

Laura contributed $15 toward the purchase of the video game.

Explanation:

The question is asking to determine the amount contributed by Laura to buy a video game for their brother, Liam, if the entire cost of the game is $45 and Laura contributed half as much as Lilly. For simplicity, let's assume Lilly contributed x dollars. Then Laura, contributing half as much, would have contributed x/2 dollars. Given that their total contribution is $45, we set up the equation x + x/2 = 45. Solving for x, we find that Lilly contributed $30 and Laura, half of this, contributed $15.

Help me please with this

Answers

Answer:

(b) 240

Step-by-step explanation:

First, we use the Pythagorean formula using the given side lengths to find x. Then we use x to find the side lengths. Then we add the side lengths to find the perimeter.

Pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

We see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. The only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

Replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240

Answers

Answer:

( 212 - 0 )/ ( 100 - 32 ) = 212 / 68 = 3.11 ;

Step-by-step explanation:

Let m = slope

The answer is 12a3 + 2a + 23a + 18

To find the product of two expressions, we use the distributive property and multiply each term from the first expression with each term from the second expression, then combine the like terms.

The product of[tex](3a + 2)(4a^2 - 2a + 9) is 12a^3 - 6a^2 + 23a + 18.[/tex]

To find the product of two binomials, you can use the distributive property. In this case, you multiply each term in the first binomial, 3a and 2, by each term in the second binomial, 4a^2, -2a, and 9, and then combine like terms.

[tex](3a + 2)(4a^2 - 2a + 9) = 3a * 4a^2 + 3a * (-2a) + 3a * 9 + 2 * 4a^2 + 2 * (-2a) + 2 * 9[/tex]

Now, perform the multiplications:

[tex]12a^3 - 6a^2 + 27a + 8a^2 - 4a + 18[/tex]

Combine like terms:

[tex](12a^3 - 6a^2) + (27a - 4a) + 1812a^3 - 6a^2 + 23a + 18[/tex]

option C.

The statement that best describes a square is: A special rectangle that has four sides of equal length. This statement aligns with the definition of a square within the field of geometry, where a square is understood as a type of rectangle with all sides being the same length. Therefore, the correct answer is C. A special rectangle that has four sides of equal length.

A square indeed has four right angles, similar to a rectangle. By extension, it has congruent opposite sides and equal angles, but the defining feature that differentiates a square from other rectangles is the fact that all four sides are of equal length. The concept of rectangles forming squares can be seen in the given reference, implying that equal rectangles can be arranged to form a square - a concept important in understanding how a square is a special case of a rectangle.

Answers

Answer:

7 7/12

Step-by-step explanation:

Find the amount of rolls in all that were donated:

60 x 12 = 720.

The total amount used is 679. Subtract 679 from 720:

720 - 629 = 91.

Find the amount per dozen. Divide 91 with 12:

91/12 = 7 7/12

7 7/12 is your answer.

~

Final answer:

The local Youth Baseball League used 56 dozen rolls with 7 extra rolls for a total of 679 hot dogs, which is expressed as 56 7/12 dozen.

Explanation:

The local Youth Baseball League served a total of 679 hot dogs using rolls from the grocery store.

If a dozen represents 12 items, we need to calculate how many dozens of rolls were used in this circumstance.

Since 679 hot dogs were served and each dozen contains 12 rolls, we can divide 679 by 12 to find the number of dozens.

Dividing 679 by 12, we get:

679 ÷ 12 = 56 dozens with a remainder of 7.

Therefore, 56 dozen rolls were fully used, with an additional 7 rolls from another dozen.

To express this in mixed number form, it would be 56 7⁄12 dozen rolls.

What will be the coordinates of vertex A of the image?

Answers

Answer:

(1.0)

Step-by-step explanation:

we know that

The scale factor of the dilation is 0.25 ----> given problem

The coordinates of point A(-5,-3) and F(3,1)

step 1

Find the x-coordinate of point A'

The horizontal distance between A and F is equal to

AFx=3-(-5)=8

The horizontal distance after dilation between A'F is equal to

A'F=0.25*8=2

so

the x-coordinate of vertex A' is equal to the x-coordinate of F minus the horizontal distance after dilation A'F

A'x=3-2=1

step 2

Find the y-coordinate of point A'

The vertical distance between A and F is equal to

AFy=1-(-3)=4

The vertical distance after dilation between A'F is equal to

A'Fy=0.25*4=1

so

the y-coordinate of vertex A' is equal to the y-coordinate of F minus the vertical distance after dilation A'F

A'y=1-1=0

therefore

The coordinates of vertex A of the image is (1.0)

of each type of coin does Rebecca have?

Answers

Answer:

Rebecca has 18 nickels and 27 dimes

Step-by-step explanation:

Let x be the number of nickels Rebecca has, then 45-x is the number of dimes she has.

The total value of Rebecca's coins is $3.60.

1 nickel - 5 cents

x nickels - 5x cents

1 dime - 10 cents

45-x dimes - 10(45-x) cents

Total x nickels and 45-x dimes is 5x+10(45-x) cents that is $3.60=360 cents. So,

5x+10(45-x)=360

5x+450-10x=360

5x-10x=360-450

-5x=-90

5x=90

x=18

45-x=45-18=27
