Answer:

about 196

Step-by-step explanation:

Area= pi x radius squared.

If the area is 615, then you plug that into the formula

A=3.14x r squared= 615

Divide 615/3.14= about 195.54

Find the square root of 195.54 it equals about 14,

Multiply by two, about 196

Answer:

2

Step-by-step explanation:

To solve this equation I used the quadratic formula.

1. Place the units into the following formula. -b+-sqrtb^2-4ac

                                                                                  2a

2. After placing the units into the formula it should be -1+-sqrt1+24

                                                                                                   2

3. This should leave you with two possible answers -3 and 2 after solving it. The answer can not be negative of course cause there is no such thing as a negative time. So the answer has to be 2.

Answer:

x=-8, y= -43

Step-by-step explanation:

y = 6x + 5

y= 4x - 11

Since both equations are equal to y, we can set them equal to each other

6x + 5= 4x - 11

Subtract 4x from each side

6x-4x+5 = 4x-4x-11

2x+5 = -11

Subtract 5 from each side

2x+5-5 = -11-5

2x = -16

Divide each side by 2

2x/2 = -16/2

x = -8

Now we need to find y

y = 6x+5

y = 6(-8) +5

   -48+5

   -43

Answer:

x = -8 y = -43

Step-by-step explanation:

y = 6x + 5

y= 4x - 11

6x + 5 = 4x - 11

2x = -16

x = -8

y = 4(-8) - 11

y = -32 - 11

y = -43

Answer: The mean is the average of all the values. The median is the number that falls in the exact center of all the measurements, while the mode is the number that occurs most frequently. ... One way to measure variability, range, is the difference between the highest and lowest values in a data set.

Step-by-step explanation: Ok?

Answer:

The mean value = $80.5

Step-by-step explanation:

The value of her last six spendings are $109, $72, $99, $15, $99, and $89.

For the mean.

Mean = Total spendings/number

Mean =483/6

Mean = $80.5

For the median.

Lets arrange it in ascending order

$15 ,$72, $89, $99, $99, $109

The middle values are two.

Median = (89+99)/2

Median = 188/2

Median = $94

For the mode

$15 ,$72, $89, $99, $99, $109

Highest occuring is $99 with two frequencies.

To convince her parents that she needs an increase in allowance she would show them the bigger spendings .

So the least value on the list it's mean value which is $80.5.

Answer:

d = 45 * t

Step-by-step explanation:

We know the equation as dert

distance equals rate * time

d = 45 * t

Answer:

d = 45 * t

Step-by-step explanation:

Step 1: Ok so for a. we can just need to build a equation representing the space the practice travels in t hours:

We can also recognize that it travels 45 mph, in order that is representing by 45(t).

d is the distance. So the equation is    d = 45(t)

Step 2: For phase b. we change 2.5 with t a the equation. Then we solve  it

d = 45(2.5)

45 * 2.5 = 112.5

the diagonal of the second square = 4.24264068712

Answer:

Step-by-step explanation:

y =  -x + 2 -------(i)

2x - y = -5  -----------(ii)

Substitute y = -x + 2 in equation (ii)

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

2x + x - 2 = - 5

3x - 2 = -5            {add 2 to both side}

3x -2 + 2 = -5 + 2

3x = -3   { divide both sides by 3}

3x/3 = -3/3

x = -1

Plug in the value of x in equation (i)

y  = - (-1) + 2

y = 1 +2

y = 3

Answer:

50 minutes.

Step-by-step explanation:

7*50 = 350

The division is one of the four fundamental arithmetic operations. The time needed by John to burn 350 calories is 50 minutes.

Division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

As it is given that to burn 7 calories by bicycling at 10mph John needs 1 minute. Therefore, the time needed to burn 350 calories by bicycling at 10mph is,

[tex]\rm Time\ Needed = \dfrac{\text{Number of calories}}{\text{Rate at which calories is burned}}\\\\\\Time\ Needed = \dfrac{350}{7}= 50\ minutes[/tex]

Thus, the time needed by John to burn 350 calories is 50 minutes.

Answer:

The slope is 4, and the y-intercept is 12.

Step-by-step explanation:

In the given question, the line goes through points (-3,0) and (-2,4).

We need to find the slope and the y-intercept of the line.

Slope is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex].

With points (-3,0) and (-2,4):

[tex]m=\frac{4-0}{-2-(-3)}=\frac{4}{1}=4[/tex]

The slope of the line is 4.

An appropriate equation for what we have so far is:

[tex]y=4x+b[/tex]

We can solve for 'b' to get the y-intercept.

Replace 'x' and 'y' with one of the coordinates and solve for 'b':

[tex]4=4(-2)+b\\4*-2=-8 \leftarrow \text {Distribute}\\4=-8+b\\4+8=-8+8+b \leftarrow \text {Addition Property of Equality} \\\boxed {12=b}[/tex]

The y-intercept is 12.

The answer should be: "The slope is 4, and the y-intercept is 12."

Answer:

The answer is d, which is the slope of 4 and the y- intercept is 12.

Answer:

The area of the circle is 314 in^2.

Step-by-step explanation:

10 inches is the radius.

The formula for the area of a circle is pi times radius squared.

So your equation would be: [tex]A=\pi (10)^2[/tex]

10^2 = 100

Then you do [tex]\pi[/tex] or 3.14 times 10 = 314.1592654 or just 314.

Hope I helped ya.

< Sarah >

The Area of Circle whose radius is 10 inch is 314 inch².

The area of a circle is the region of two-dimensional space occupied by a circle.

The area of a circle is pi times the radius squared (A = π r²).

i.e., Area of Circle = πr²

We have radius of Circle as

r = 10 inch

Using the Formula

Area of Circle = πr²

                       = 3.14 x (10)²

                       = 3.14 x 100

                       = 314 inch².

Thus, the Area of Circle is 314 inch².

Answer:

For the great pyramid of Cheops, V + F = E + 2 gives 5 + 5 = 8 + 2 which proves Euler-Descartes formula

Step-by-step explanation:

The great pyramid of Cheops is a square based pyramid therefore we have;

V + F = E + 2

Where:

V = Vertices

F = Faces

E = Edges

Hence, we have for a square pyramid;

V = 5 vertices (One at the peak, and four  at the base edges)

F = 5 faces (The four lateral or side faces and the base)

E = 8 edges ( The four lateral edges and the four base edges)

Hence;

5 + 5 = 8 + 2 which proves Euler-Descartes formula.

The total value of his large assets is $53,900.

Assets are defined as the possessions that a person or the company holds which has a value which affects positively for the person or the company.

Given that,

Amount in a checking account = $900

Amount as investments = $15,000

Amount for the car = $8000

Amount for the house = $30,000

Total value for the assets = $900 + $15,000 + $8000 + $30,000
