Total area of the circle is 1.12π square inches.

<h3>What is Area of circle?</h3>

The Area of circle is π times the square of the radius.

i.e., A = πr²

Given:

Area of one circle = 0.56π

As the second circle is also identical then the area will be same.

So, the total area of circle is

=2* 0.56π

=1.12π square inches.

Answer:

B. $33.7 mm; 54mm^2$

Step-by-step explanation:

To find the perimeter, use the formula:

P = a + b + c

P = 12 + 12 + 9.7

P = 33.7

To find area, use the formula:

A = $\frac{1}{2} bh$

A = $\frac{1}{2} (12)(9)$

A = $\frac{1}{2} (108)$

A = 54

Select all of the following tables which represent y as a function of x.x 5 10 11y 3 9 15x 5 10 11y 3 9 9x 5 10 10y 3 9 15

Answer:

Table 1 and 2 represent a function

Step-by-step explanation:

Given

Table 1

x 5 10 11

y 3 9 15

Table 2

x 5 10 11

y 3 9 9

Table 3

x 5 10 10

y 3 9 15

Required

Determine which of the tables represent that y is a function of x

For a relation to be a function; the x values must be unique.

In other words, each x value must not be repeated;

Having said that;

Analyzing Table 1

Table 1

x 5 10 11

y 3 9 15

Note that the x rows are unique as no value were repeated;

Hence, Table 1 is a function

Table 2

x 5 10 11

y 3 9 9

Note that the x rows are unique as no value were repeated;

Hence, Table 2 is a function

Table 3

x 5 10 10

y 3 9 15

Note that the x rows are not unique because 10 was repeated twice;

Hence, Table 3 is not a function

Explain how to draw a tree diagram of outcomes for this situation: Julie went to visit her aunt and uncle for the weekend. She t

Naddika [18.5K]

Answer:

A tree diagram shows all possible outcomes of two or more events.

Each branch is a possible outcome and can be labelled with a probability.

Step 1: Draw lines (branches) to represent the first set of options (slacks). Write the outcomes on the ends of the branches (brown and black).

Step 2: Draw the next set of branches to represent the second set of options (sweaters). Write the outcomes on the ends of the branches (tan, red and white).

Step 3: Draw the final set of branches to represent the last set of options (shirts). Write the outcomes on the ends of the branches (white and gray).

We assume that the events in this scenario are independent so the probability of the first event happening has no impact on the probability of the second event or the third event happening. Therefore, the probabilities are:

P(brown slacks) = 1/2
P(black slacks) = 1/2
P(tan sweater) = 1/3
P(red sweater) = 1/3
P(white sweater) = 1/3
P(white shirt) = 1/2
P(gray shirt) = 1/2

Write these on the branches.

A rectangular piece of land to be developed as a memorial park has an area of 75 m^2. The length of the lot is three times the w

Lelechka [254]

Let length = l

width = w

length = 3 times width = 3w

Area of the land = 75 sq. m

Area = length × width = 3w×w = 75

3w²=75

w²=25

w=5 m

length = 3×15 = 15m

Now lets make the figure with the path of width x meters

(Refer the attached figure for easy understanding)

The inner length is the length of the rectangle reduced by x meters on either side due to the path

that is 15-x-x = 15-2x

the inner width is the width reduced by x meters in either side

= 5-x-x = 5-2x

Now lets calculate the inner area = inner length × inner width

(15-2x)×(5-2x)

= $75-30x-10x+4x^{2}$

= $75-40x+4x^{2}$ sq. m

Now the function to calculate the cost

f(x) is given by $3.00 × area of the inner land

f(x) = 3 × {75-40x+4x²)

= 225-120x+12x²

= 12x²-120x+225
