A rectangular parking lot has an area of 682 square yards.The lot is 22 yards wide.What is the length of the parking lot?
postnew [5]

Answer:

Area of rectangle with length 'l' and width 'w' = l \times w

The area of rectangular parking lot = 682 square yards.

The width of the rectangular parking lot = 22 yards

Let the length of the rectangular parking lot be 'x' yards.

Since, area of rectangular parking lot = l \times w

682 = x \times 22

So, x=\frac{682}{22}

x=31 yards

Therefore, the length of the rectangular parking lot is 31 yards.

Zarrin [17]

Answer:

0.99, 0.6, 1, 0.01, 0, 0.3 respectively

Step-by-step explanation:

This event is extremely likely but there will be some occasions when it does not occur.  The correct match is 0.99

This event will occur more often than not. The correct match is 0.6

This event will always occur. The correct match is 1

This event is very unlikely, but it will occur once in a while in a long sequence of trials. The correct match is 0.01

This event is impossible. It can never occur. The correct match is 0

This event is reasonably likely, and will occur sometimes, but not most of the time. The correct match is 0.3

Use the figure to find the length HJ. Assume △DEF ≅ △GHJ.<br> *I GOT 30*
solniwko [45]
Yes, HJ = 30 ft.

It tells us that triangle DEF = triangle GHJ.

By seeing this we know without looking at the triangles that EF is going to be the same as HJ because when they say a figure is the same as another and list the letters such as 'DEF' and 'GHJ' they will list them in the same order.

So

'DEF' = 'GHJ' we get:

'DE' = 'GH'

'EF' = 'HJ'

And we can do the last and first letters:

'FD' = 'JG'

And since we know 'EF' = 'HJ' and that they already told us 'EF' was 30, we know HJ will be 30.
