Answer:

The circumference of the pool is 62.8 foot long and the area of the circle formed by the pool is 314 ft².

Step-by-step explanation:

The circumference of the pool can be found by calculating the arc's length of the edges of the pool. This is done by using the following formula:

[tex]circumference = 2*\pi*r[/tex]

Where the radius is half the diameter, applying the data from the problem we have:

[tex]circumference = 2*3.14*10 = 62.8 \text{ ft}[/tex]

The area of the circle formed by the pool can be found using the following expression:

[tex]area = pi*r^2 = 3.14*(10)^2 = 314 \text{ ft}^2[/tex]

The circumference of the pool is 62.8 foot long and the area of the circle formed by the pool is 314 ft².

Answer:

(A)

Step-by-step explanation:

As you can see, the figure can be divided into a square of side 2cm and a rectangle of sides 5cm and 3cm so we find the area of both and add.

Area of the square

= 2x2 = 4cm^2

Area of the rectangle

= lxb

= 3x5

= 15 cm^2

Therefore the area of the entire figure

= Area of square + area of rectangle

= 15+4

= 19 cm^2

So the correct option is (a)

Hope this helps:)

Answer:

Option 1

Step-by-step explanation:

I broke the figure up into two shapes. One of them was a square and the other one was a big rectangle. I calculated the two areas and added them back together.  My work is attached in the picture.

Area of a square is: s^2

's' -side length

Area of a rectangle is: b * w

'b' - base or length

'w' - width

The area of the figure should be 19cm².

False

The cost of a lion toy is $12

An equation between two variables with a constant in the form of ax +by =c is called a linear equation.

Given the cost of 4 bear toys and a lion toy is $70.

And If the cost of a lion toy and 2 bear toys is $41,

Write a linear equation for the above equation

4B +1L =70

2B +1L =41

By solving the above equations we get B= $14.5 and L=12

Thus the cost of a bear is $14.5 and cost of a lion is $12.

Answer:

38/60 or 19/30

Step-by-step explanation:

The question isn't fully attached as stated by the person who submitted it.

The fraction of the cakes he has left is ( 5 / 6 ). The remaining number of cakes is 50.

Expression in maths is defined as the collection of numbers, variables, and functions using signs like addition, subtraction, multiplication and division.

The fraction is calculated as:-

The remaining fraction = 1 - ( 1 / 6 )

                                      = ( 6 - 1 ) / 6

                                      = 5 / 6

The remaining number of cakes,

Remaining number = 60 x ( 5 / 6 )

Remaining number = 50

Hence, the remaining number of cakes is 50.

Answer:

- [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Here [ a, b ] = [ - 8, 2 ] , thus

f(b) = f(2) = - 4 ← read from graph

f(a) = f(- 8) = 1 ← read from graph, thus

average rate of change = [tex]\frac{-4-1}{2-(-8)}[/tex] = [tex]\frac{-5}{10}[/tex] = - [tex]\frac{1}{2}[/tex]

Answer:

y = 1.56 x - 4.105

which agrees with answer "B" in your list of possible options.

Step-by-step explanation:

Notice that you are expected to use some type of regression tool for this problem. either a computer program or a handheld graphing calculator with such functionality.

I have entered the set of data points in two separate lists, one for the x-values,and another one for the y-values, and run the linear regression tool in order to get the best fitting line. See what I obtained using this tool in the screen capture I am attaching below.

Notice that the line of best fit reads:

y = 1.56015038 x - 4.10526316

showing clearly the slope and y-intercept of the line of best fit.

Rounding slope and y-intercept to the third decimal, we get:

y = 1.56 x - 4.105

which agrees with answer "B" in your list of possible options.

Step-by-step explanation:

With this, you could find out how much money she had in total.

Sample Response:

To write a two-variable equation, I would first need to know how much Maya’s allowance was. Then, I would need the cost of playing the arcade game and of riding the Ferris wheel. I could let the equation be cost of playing the arcade games plus cost of riding the Ferris wheel equals the total allowance. My variables would represent the number of times Maya played the arcade game and the number of times she rode the Ferris wheel. With this equation I could solve for how many times she rode the Ferris wheel given the number of times she played the arcade game.

Mean = 3550

SD = 870

Find P(1810 <x<4420)

z = x -mean / sd

Answer:

  H(t) = -10·cos(t/20) +20

Step-by-step explanation:

The range of heights is ...

  30 m - 10 m = 20 m

The amplitude of the cosine function is half that, or 10 m. Here, the function starts off at a minimum, whereas the parent cosine function starts at a maximum. That means the parent function is reflected vertically, so the amplitude coefficient in H(t) is negative.

The midline of the cosine function is the average of the extreme heights, so is ...

  midline = (30 m +10 m)/2 = 20 m

The period of the function is double the time it takes to go from a minimum to a maximum, so is ...

  p = 2(20π) = 40π . . . . seconds

In the given function form ...

  H(t) = a·cos(bt) +d

the amplitude is a=-10; the coefficient b is 2π/p = 1/20; and the midline is d = 20. Then the function is ...

  H(t) = -10·cos(t/20) +20
