Michelle is buying carpet for a room with the dimensions shown. Michelle calculates that the area she will cover with carpet is

butalik [34]

The area of the room is $147\frac{1}{2}$ square feet so Michelle's reasoning was incorrect.

Step-by-step explanation:

Step 1:

To calculate the area of the given room, we divide the unknown shape into known shapes.

The room's shape is made of 2 rectangles.

The area of a rectangle is the product of its length and its width.

One rectangle has a length of 10 feet and a width of $12\frac{1}{2}$ feet.

The other rectangle has a length of $15-10=5$ feet and a width of $4\frac{1}{2}$ feet.

Step 2:

The area of the first rectangle $= (10)(12\frac{1}{2} )= (10)(12.5)= 125$ square feet.

The area of the second rectangle $= (10)(4\frac{1}{2} )= (5)(4.5)= 22.5$ square feet.

The total area of the room $= 125+22.5 = 147.5 = 147 \frac{1}{2}$ square feet.

The area of the room is $147\frac{1}{2}$ square feet so Michelle's reasoning was incorrect.

A ride-share company has a fee that includes a fixed cost and a cost that depends on both the time spent travelling, in minutes,

zlopas [31]

Answer:

the cost of Roy's ride is $23.05

Step-by-step explanation:

According to the Question,

Let, Cost of per minute charge is 'x' & Cost Of Per Kilometre charge is y .

Given, A ride-share company has a fee of the fixed cost of a ride is $2.55 .
And, The Total cost of the Ride depends on both the time spent on travelling(in minutes), and the distance travelled(in kilometres) .

⇒ Judy's ride costs $16.75 . but the actual cost after deducting the fixed charge is 16.75-2.55 = $14.20, took 8 minutes & The distance travelled was 10 km. Thus, the equation for the journey is 8x+10y=14.20 ⇒ Equ. 1

⇒ Pat's ride costs $30.35 . but the actual cost after deducting the fixed charge is 30.35-2.55 = $27.80, took 20 minutes & The distance travelled was 18 km. Thus, the equation for the journey is 20x+18y=27.80 ⇒ Equ. 2

Now, on Solving Equation 1 & 2, We get

x=0.4(Cost of per minute charge) & y=1.1(Cost Of Per Kilometre charge)

Now, Roy's ride took 10 minutes & The distance travelled was 15 km . Thus, the cost of Roy's Ride is 10x+15y ⇔ 10×0.4 + 15×1.1 ⇔ $20.5

Hence, the total cost of Roy's ride is 20.5 + 2.55(fixed cost) = $23.05
