A water sprinkler sprays water over a distance of 36 feet while rotating through an angle of 140 degrees. What area of lawn rece

aniked [119]

Answer: $1,583.36\ ft^2$

Step-by-step explanation:

The formula for calculate the area of a Sector of a circle is:

$A=\pi r^2(\frac{C}{360})$

Where "C" is the central angle in degrees and "r" is the radius.

Based on the data given in the exercise, you can identify that:

$r=36\ ft\\C=140\°$

(See the figure attached)

Then, you can substitute these values into the formula and then evaluate, in order to calculate the area of lawn that receives water.

The result is:

$A=\pi r^2(\frac{C}{360})\\\\A=\pi (36\ ft)^2(\frac{140\°}{360})\\\\A=1,583.36\ ft^2$

a car rental company charges an initial fee plus a constant fee per kilometer driven this table compares a total distance driven

ollegr [7]

Answer:

$120

Step-by-step explanation:

The initial fee that was charged is the y-intercept of the equation that represents the situation given.

Using the slope-intercept equation, y = mx + b, find m and then find b, which is the initial fee.

Where, x = distance, y = price, m = slope, and b = y-intercept, which is the initial fee that was charged that we are looking for.

First, using two pairs, (105, 183) and (140, 204), find the slope (m):

$m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{204 - 183}{140 - 105} = \frac{21}{35} = \frac{3}{5}$

m = ⅗

To find the y-intercept, b, substitute x = 105, y = 183, and m = ⅗ into $y = mx + b$ .

$183 = \frac{3}{5}(105) + b$

$183 = 63 + b$

Subtract 63 from each side

$183 - 63 = b$

$120 = b$

The initial fee of the company is $120.

On one side of a football stadium are 30 suites on the circle level. Fourteen of the suites have 24 seats each, and the rest hav

hram777 [196]

<span>The simplest form of a fraction occurs when the numerator and denominator cannot get any smaller (while still being integers)

In the stadium there are 30 suites.

14 suites.............24 seats
16 suites..............18 seats

The suites with 24 seats are 14 out of 30 which can be represented as 14/30.

However, the simplest fraction would be

7*2 7
------- = ------
15*2 15

This is why Tyler is incorrect</span>
