The area of a circle is 153. 86 square meters. What is the the diameter of the circle? Use 3. 14 for π.


d =

meters

Answers

Answer:

Option (2). 14 m

Step-by-step explanation:

Formula to get the area of a circle 'A' =

where r = radius of the circle

Given in the question,

Area of the circle = 153.86 square meters

By putting the values in the formula,

153.86 = πr²

r = [tex]\sqrt{\frac{153.86}{\pi } }[/tex]

r = [tex]\sqrt{49}[/tex]

r = 7 meters

Diameter of circle = 2 × (radius of the circle

                             = 2 × 7

                             = 14 meters

Therefore, diameter of the circle is 14 meters.

- A jar contains 55 quarters and dimes. The total value of the coins is $8.50. Find the
number of quarters and dimes in the jar.

Answers

Answer:

20 quarters and 35 dimes.

Step-by-step explanation:

Let number of quarters = q

Therefore number of dimes = 55 - q

By condition, q * 25 + (55 - q) * 10 = 850 [all converted to cents]

25q + 550 - 10q = 850

25q - 10q = 850 - 550

15q = 300

q = 300/15 = 20

Therefore, number of quarters = 20

and number of dimes = 55 - 20 = 35

What is the slope of the line that passes through the points (4, 8)(4,8) and (8, 6)(8,6)? Write your answer in simplest form.

Answers

Using linear function concepts, it is found that the slope of the line that passes through points (4,8) and (8,6) is of -0.5.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

The line goes through points (4,8) and (8,6), hence when x changes by 4, y changes by -2, and the slope is given by:

m = -2/4 = -0.5.

Answers

Hi!

Your answer is [tex]x^2+x+6[/tex]

We are asked to find the floor space it covers, which we can solve for by finding the area of the rectangular rug, given its dimensions.

Dimensions:

(x - 2) x (x + 3)

Area of a rectangle:

Length x Width = Area

Plug dimensions into the formula:

[tex](x - 2)(x +3)[/tex]

Use the Distributive Property and FOIL method to solve (if you are not familiar with the FOIL method, see the image attached below):

The profit (p) a baker earned, in dollars, is proportional to the number of muffins (m) sold. This equation represents this relationship.

P = 0.75m
enter the profit earned for each muffin sold.

Answers

P = 0.75m represents the proportional relationship, therefore, the profit earned for each muffin sold is: $0.75.

What is Proportional Relationship?

If two variables, i.e. P and m are directly proportional to each other, the relationship between them can be represented as P = km, where k is the constant.

Given that P = 0.75m represents the proportional relationship between the profit earned and muffins sold, the constant, k, is 0.75, which is the profit earned for each muffin sold.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

To find the surface area of this square pyramid

Now, We know that;

the surface area of this square pyramid is,

⇒ SA = B + 1/2 pl

Where, B represents the area of the base. p represents the perimeter of the base. l represents the slant height.

Now, We get;

B = 12 x 8

B = 96

p = 2 (12 + 8)

p = 40

l = 10

Thus, the surface area of this square pyramid is,

⇒ SA = B + 1/2 pl

⇒ SA = 96 + 1/2 x 40 x 10

⇒ SA = 96 + 200

⇒ SA = 296 cm²

Explain how you would find the coordinates of the image (5, 2) if it was reflected over the x-axis and then that image was reflected over the y-axis what would be the end result?

Answers

Answer:

the end result is (-5 , -2)

Step-by-step explanation:

Let A’ be the image of A(5 ,2) by reflection over the x-axis

and Let A’’ be the image of A’ by reflection over the y-axis

Formula:

➽if we reflect a point M of coordinates (x , y) over the x-axis we get the image point M’ of coordinates (x , -y)

➽ if we reflect a point N of coordinates (z , t) over the y-axis we get the image point N’ of coordinates (-z , t)

_____________________________

According to the formula :

A(5,2) ———-> A’(5 , -2) ———-> A’’(-5 , -2)

Answer: To find the image after a reflection over the x-axis, I would negate the y-coordinate. To find the image after a reflection over the y-axis, I would negate the x-coordinate. So, reflecting the point (5, 2) over the x- and y-axis, I would get (–5, –2).
