To find how many square feet her patch of lawn is, we need to find what the area of the lawn is. To find the area of a rectangle (which is what the patch of lawn is), we need to multiply length and width. The length of this rectangle is 10 feet and the width of this rectangle is 9 feet. To figure out what 10 * 9 is, we need to multiply all parts of 10 (10, and 0) by 9. 10 * 9 = 90, while 0 * 9 = 0. Adding them together, we get that the piece of lawn is 90 square feet.
Answer:
The wheel will make 40 revolutions.
Step-by-step explanation:
We are given;
Diameter = 77 cm = 0.77m
Radius = 0.77/2
Radius = 0.385 m
Speed = 1.1 m/s
time = 1min 28 sec = 88 sec
Now, we know that;
Distance = speed×time
Thus;
Distance = 1.1 × 88
Distance = 96.8 m
Also,
Number of revolution = distance/circumference
Number of revolutions = 96.8/(2 × π × 0.385)
Number of revolutions ≈ 40
-22 is a whole, rational, integer.
-22 is not irrational ... it's the ratio of -22 to 1 .
The natural numbers are the counting numbers ... 1, 2, 3, etc.
-22 is not one of those.
Answer: the area is 224
