yawa3891 [41]

Answer: 8


Step-by-step explanation:

Given: Pedro cut a sheet of poster board into 10 equal parts.

let x be the total sheet.

then, one part of sheet= \frac{1}{10} of the sheet

Now, His brother used some of the poster board and now 8/10 is left.

Therefore, if Pedro wants to make a sign from  each remaining part of the poster board.

then, The number of signs he can make= \frac{8}{10}\div \frac{1}{10}=\frac{8}{10}\times\frac{10}{1}=8

Hence, Pedro can make 8 signs.

Addie walked 2 1 2 miles in 45 minutes. Suzie covered 2 2 5 miles in 2 3 of an hour. Which girl walked faster? By how much?
kobusy [5.1K]

Answer:

Suzie walks faster by 0.27 miles per hour.

Step-by-step explanation:

Addie walked 2\frac{1}{2} miles in 45 minutes and Suzie covered 2\frac{2}{5} miles in \frac{2}{3} of an hour.

So, Addie walked 2.5 miles in 45 minutes i.e. \frac{45}{60} = 0.75 hours.

Therefore, the walking speed of Addie is \frac{2.5}{0.75} = 3.33 miles per hour.

Again, Suzie covered 2\frac{2}{5} i.e. 2.4 miles in \frac{2}{3} i.e. 0.67 hours.

So, the walking speed of Suzie is \frac{2.4}{0.67} = 3.6 miles per hour.

Hence, Suzie walks faster by (3.6 - 3.33) = 0.27 miles per hour. (Answer)

I 11 x - 22 I > 22
∴ 11x-22 > 22          OR          (11x -22) < -22
∴ 11 x > 44             ::::::::          11x - 22 < -22
    x > 4                   ::::::::              x < 0

∴ x ∈ ( -∞ , 0 ) ∪ ( 4 , ∞)
∴ The correct choice is number 1
