Answer:

49.6 square meters

Step-by-step explanation:

first, circumference is 2*pi*r, so we want to find r.  so we take 2*pi*r=24.8 and solve for r which is 4.

Now, area is pi*r^2 so pi*4^2 = pi*16 = 49.6

49.6 square meters.



First, let’s find the radius of the rug. The radius is equal to the circumference divided by 2pi, or 2 * 3.1, which is 6.2, in this case.

24.8/6.2

4

The radius is 4. The area of a circle is pi times the radius squared.

3.1 * 4^2

3.1 * 16

49.6

So, the area of the rug is 49.6 square meters.

Maggie created this scale drawing of a soccer field, using a scale factor of 1 inch : 12 yards. She wants to make another scale
larisa [96]

The length and width of the new scale drawing is 36 inches and 24 inches respectively.

The given parameters:

  • <em>Original scale of the soccer field, 1 inch : 12 yards</em>

The original length and width of the soccer field is calculated as follows;

1 inch : 12 yards

  • original width = 6 x 12 yards = 72 yards
  • original length = 9 x 12 = 108 yards

For the new scale of 1 inch : 3 yards, the new length and width are represented as;

<em>the </em><em>new width</em><em>:</em>

\frac{1 \ inch}{x} = \frac{3 \ yards}{72 \ yards} \\\\x = 24 \ inches

<em>the </em><em>new length</em><em>:</em>

\frac{1 \ inch}{x} = \frac{3 \ yards}{108 \ yards} \\\\x = 36\ inches

Thus, the length and width of the new scale drawing is 36 inches and 24 inches respectively.

A rental car company offers a rental package for a mid-size car.
skelet666 [1.2K]

Answer:

y=45x+40

Step-by-step explanation:

Let

x -----> the number of days

y ----> the total cost in dollars,

we know that

The equation of a linear function in slope intercept form is equal to

y=mx+b

where

m is the slope o rate of the linear equation

b is the y-coordinate of the y-intercept

Remember that the y-intercept is the value of y when the value of x is equal to zero

In this problem we have

The slope is equal to the rental cost per day

so

m=45\frac{\$}{day}

When the number of days is equal to zero (x=0) the total cost is equal to $40 (administrative fee for the cleaning and maintenance of the car)

The y-intercept is the point (0,40)

so

b=\$40

substitute the values

y=45x+40

Elizabeth has two identical number cubes. both cubes have faces numbered 1 through 6. If Elizabeth rolls each cube once, What is
Lelechka [254]
The sample space for the two identical dice (outcomes):

(1,1)(1,2)(1,3)(1,4)(1,5)(1,6)

(2,1)(2,2)(2,3)(2,4)(2,5)(2,6)

(3,1)(3,2)(3,3)(3,4)(3,5)(3,6)

(4,1)(4,2)(4,3)(4,4)(4,5)(4,6)

(5,1)(5,2)(5,3)(5,4)(5,5)(5,6)

<span>(6,1)(6,2)(6,3)(6,4)(6,5)(6,6)</span>

<span>
</span>

<span>So if Elizabeth rolls each cube once, there is 36 (6 x 6) possible outcomes.</span>

<span>Let E = event of getting a sum of 10.</span>

<span>The number which is a sum 10 will be:</span>

E = [(4,6), (5,5),(6,4)]

P(E) = number of favorable outcomes divided by total number of possible outcomes

        = 3 / 36 or 0.083
