17.24
Since 7 comes after 5 we need to round to the next number.....18.00
17.24 rounded to ones = 18.00
Hope I helped:P
We want to simplify √(-48).
Note that
i² = -1 by definition.
Therefore
Answer: c.
Step-by-step explanation:
the average change rate of a function f(x) in an interval [x1 .. x2] is
(f(x2) - f(x1)) / (x2 - x1)
in our case that is
(7000 - 2500) / (20 - 0) = 4500 / 20 = 225
the population changed in average by 225 people per year from 1900 to 1920.
Answer:
2
Step-by-step explanation:
She needs to have 6 portions of 1/5 pie size.
6 portions of 1/5 pie size is 6/5 of a pie.
6/5 of a pie is the same as 1 1/5 (one and one-fifth) pies.
Since she only bakes full pies, she must round up to the next higher whole number, so she must bake 2 pies.
Answer:yes, the lawn can be watered completely by 4 installed sprinklers.
Step-by-step explanation:
The lawn is rectangular and its area is 32 square yards. Sprinklers are to be installed and each sprinkler waters in a circle. The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
If each sprinkler can completely water a circular area of lawn with a maximum radius of 2 yards., the the maximum area that can be watered by each sprinkler would be
Area = 3.14 × 2² = 12.56 yards²
If 4 sprinklers are completely installed, then the total area that they can water would be
12.56 × 4 = 50.24 yards²
Therefore, the lawn can be watered completely by 4 installed sprinklers.
