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.

The tree diagram represents an
olga_2 [115]

Using it's concept, considering the tree diagram, the probability of event C is given as follows:

P(C) = 0.26.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

Each node at the tree is a multiplication, hence the probability of event C is given as follows:

P(C) = 0.6 x 0.3 + 0.4 x 0.2 = 0.18 + 0.08 = 0.26.

If the area of a circle is 58 square feet, find the circumference
Blizzard [7]

Answer:

C≈27 feet

Step-by-step explanation:

A=πr²

A/π=r²

√A/π =r or –√A/π=r (refused)

then r =√(A/π) =√(58/π) =4.297829403 feet

C=2πr=2π(4.297829403)=27.00405856≈27 feet
