Answer:
179 square meters
Step-by-step explanation:
you can look at the figure into 3 different rectangles. 2*7=14, 2*6=12, 17*9=153. 14+12+153=179.
Answer:
The period of function is 5 and amplitude is 3.
Step-by-step explanation:
<em>The period of the function is the time interval after which it repeats itself.</em>
It means the time interval after which the same value of graph is attained.
In the above case looking at the peak point at time 5 seconds, the same value is obtained at time 10 seconds.
Thus the time interval is (10 - 5) 5 seconds.
<em>Amplitude is the maximum value attained by the graph in the complete interval.</em>
In the above case, the maximum value attained is 3.

3.14(12)(2)(7) = 527.52
Answer:
10
Step-by-step explanation:
Let c = sum of ages of all children.
mean age of all children = c/15 = 7
c = 15 * 7 = 105
The sum of the ages of all children is 105.
Let b = sum of ages of the 9 boys.
mean age of boys = b/9 = 5
b = 9 * 5 = 45
The sum of the ages of the boys is 45.
The sum of the ages of the girls is c - b.
c - b = 105 - 45 = 60
The number of girls is 15 - 9 = 6
mean age of girls = (sum of ages of the girls)/(number of girls) =
= 60/6 = 10
