Answer:
11 lots are for sale.
Step-by-step explanation:
This is as simple as:
Since Mr. Smith divided the land into 1/2 acre lots, you'd just divide it by the amount he has.
The perimeter is the sum of the outside dimensions.
b1 = 87 - 32 - 14 - 13 = 28 in.
Area = (32 + 28) /2 x 12 = 60/2 x 12 = 30 x 12 = 360 square inches.
Divide area by the amount 1 can covers:
360 / 50 = 7.2 cans, round up to 8 cans are needed.

i mite be wrong but the 2 choice
Step-by-step explanation:
Based on the time taken by the jet when flying with the wind versus against it, the rate of the jet and jet streams are:
- In still air = 1,170 mph
- Rate of wind = 170 mph
<h3>What is the speed of the jet?</h3>
The speed of the jet flying against the wind is:
= 3,000 / 3
= 1,000 mph
The speed with the jet stream is:
= 5,360 / 4
= 1,340 mph
Assuming the speed of the jet is x and the rate of wind is y, the formulas are:
x - y = 1,000
x + y = 1,340
Solving gives:
2x = 2,340
x = 1,170 mph
The rate of jet stream is:
x - y = 1,000
1,170 - y = 1,000
y = 170 mph

The proportion that Alexandra can use to find r is 9 cups of water and 4 cups of dry rice
If Alexandra uses 12 cups of water and 6 cups of dry rice to make 18 cups of cooked rice, this can be expressed as:
To get the proportion "r" for the amount of dry rice to use to make 4 cups of cooked rice, we can write:
Divide both expressions:
Hence the proportion that Alexandra can use to find r is 9 cups of water and 4 cups of dry rice
