Calculate the area of the room and then subtract the area of the tiled floor.


area of room = 11 3/4 x 5 = 58 3/4

Area of tiled floor = 7 1/2 x 3 1/4 = 24 3/8


area of carpet = 58 3/4 - 24 3/8 = 34 3/8


answer: 34 3/8

The point P(5,1) lies on the curve y=5x. If Q is the point (x,5x), find the slope of the secant line PQ for the following values
sveta [45]

Answer:

5

Step-by-step explanation:

We have been given that the point P(1,5) lies on the curve y=5x. Q is the point (x,5x). We are asked to find the slope of the secant line PQ for x=5.1.

Let us find y-coordinate corresponding to x=5.1 for point P as:

y=5(5.1)=25.5

Now, we will use slope formula to find required slope.

m=\frac{y_2-y_1}{x_2-x_1}  

Let point (1,5)=(x_1,y_1) and point (5.1,25.5)=(x_2,y_2).

Using these points in slope formula, we will get:

m_{PQ}=\frac{25.5-5}{5.1-1}=\frac{20.5}{4.1}=5

Therefore, the slope of the line PQ is 5.

Jake has two pet guinea pigs named fluffy and scruffy. Fluffy is8 1/8 inches long. Scruffy is 10 1/4 inches long. How much longe
miss Akunina [59]

Answer:

Scruffy is 2\frac{1}{8} inches longer than Fluffy.

Step-by-step explanation:

Length of Scruffy = 10\frac{1}{4} inches

Length of Fluffy = 8\frac{1}{8} inches

We have to calculate how much Scruffy is longer than Fluffy.

Difference of their lengths = 10\frac{1}{4}-8\frac{1}{8}

                                            = (10 - 8) + (\frac{1}{4}-\frac{1}{8})

                                            = 2 + (\frac{2-1}{8})

                                            = 2 + \frac{1}{8}

                                            = 2\frac{1}{8} inches

Therefore, Scruffy is 2\frac{1}{8} inches longer than Fluffy.
