IF I travel (4+x) miles per hour for 2 hour and I travel the same distance at (4-x) miles per hour in 3 hours, what is x?

1 answer:

3 0

So this is saying that the two distances travelled are the same.
Now... Distance = Speed * Time
Thus (4+x)*2=(4-x)*3
So 8+2x=12-3x
Thus, 5x=4
so x=0.8

If the area of a circle is 121pie square units, what is the diameter

velikii [3]

Since you are given the area, we can solve for radius with this equation:
$A_c = \pi r^2$
$r = \sqrt{ \frac{A_c}{ \pi } } = \sqrt{ \frac{121 \pi }{ \pi } } = \sqrt{121} = 11$

The radius is 11, so the diameter must be 2 times that, which is 22. With the correct units, the answer is 22 units²

Mr. and Mrs. Simpson went to the movies. They bought some popcorn for $25.50, two boxes of candy for $18 and two drinks for $14.

Ne4ueva [31]

You add all of those numbers together and get your answer which is 60, so basically like this

25.50 + 14.25 + 18 + 2.25 = 60

Why is the product of 9s diagonal?

Nadusha1986 [10]

Answer:

A. With each 9s fact you add another 9, which means you go straight down a row and back one space. This creates a diagonal pattern in the grid.
