Answer:
A. 821.5 Square Yards
Step-by-step explanation:
30 x 30= 900
900 is the area for the whole park
To find the pool area you need to do pi times Radius squared
so 3.14 x 5 x 5
That equals 78.5 for the pool area.
So to find the grass area you need to subtract the pool area from the park
900 - 78.5 = 821.5 square yards!
478.25 times 4(weeks in a month) =1913
1913 times 12 (months in a year)
EQUALS AROUND 22,956 a year , that would be your annual salary.
Answer:
Step-by-step explanation:
I'm not certain I understand your question.
Let's start at the beginning. What you are supposed to do is find the area of the 4 triangles.
QRP is one of the tringles. It has a height of RS which is 6 cm. The base of the triangle comes from the square on the bottom of the diagram (and yes it is an optical illusion).
The square has a side length of 8 cm.
Area QRP = 1/2 * base * height
base = 8 cm
height = 6 cm
Area QRP = 1/2 * 8 *6 = 24 Oh that's where you got 24 * 4
There are 4 triangles that are the same as QRP so the answer is 24*4
The base of the triangle is included. It is just a bit disguised. It comes from the 24. Excellent question.
For the shown graph, let us make some notes to get the correct option.
First let us see that are the positive and what are the negative values of y's in the shown graph.
Note: The values of y's down the x-axis are negative and up the x-axis are positive.
From (-infinity to -2.7) it has negative values of y, that is less than 0 because it's down the x-axis.
From (-1 to 0.08) it also has negative values of y, that is less than 0.
Therefore, correct option is option B). f(x) < 0 over the intervals (-infinity, -2.7) and (-1 ,0.8).
