Answer:
34.562
Step-by-step explanation:
To find the perimeter of a circle, it's 2 * the radius * pi. In this case, we have a semicircle, so it would be the circle's perimeter divided by 2, or just the radius * pi.
The radius, 11, times pi (3.142), is 34.562.

Answer: The correct answer is 341 children
Step-by-step explanation:
Firstly you solve for the number of children that like both types of ice cream.
Let us assume it to be x
(150 - x )+ x + (125 - x) + 166 = 391
150 + 125 + 166 - x + x - x = 391
441 - x = 391
X = 441 - 391
X = 50
Since 50 children like at least one type of ice cream, subtracting it from the total no. of children will give the number of children that like at most one type
Therefore, 391 - 50 = 341 children
Alternatively,
Sum up children who like only chocolate ice cream + pistachio ice cream only + does who don't like any type of ice cream
= (150 - 50) + (125 - 50) + 166
= 100 + 75 + 166
= 341 children
Answer:
f(-3)=3
Step-by-step explanation:
We know that f(x)=-2x-3. In order to find f(-3), we simply need to substitute x with -3.
Thus, we have:
=-2(-3)-3
=6-3
=3

Step-by-step explanation:
Answer:
0.55A dollars
Step-by-step explanation:
If 45% of the money was spent, then the percentage left was
100% - 45%, or 55%.
Thus, to answer this question, we multiply (A dollars) by 0.55:
0.55A dollars was left after the expenditure of 45% of the original amount.
