Area of a sector: 1/2r^2 theta
Need theta
Let x be theta for now
42.25 pi = 1/2r^2x
84.5pi = r^2x
84.5pi = 169x
x = 84.5pi/169 = roughly 1.57 in radians
Radians => degrees is 1.57 * 180/pi or roughly 90.
Answer:
x+y=200
xy=9,600
Step-by-step explanation:
The diagram shows rectangular parking lot with sides of x feet and y feet.
1. The area of the rectangle is given by
A=Length \times Width
A = xy -------------------------(1)
We are given that the area of the parking lot is 9,600\ ft^2, then
eq(1) becomes
9,600 = xy ---------------------(2)
2. A parking lot has a 200ft fence built along two adjacent sides of lengths x and y, then
Then the perimeter of the two adjacent sides
x+y=200
---------------------------------(3)
Thus ,The system of two equations are
x+y=200
xy=9,600
Answer:
d + 85
Step-by-step explanation:
Look at it like this,
suppose you have 1 DVD, and the mother buys 85 DVDs then you have 1 + 85 = 86 DVDS
or when you have 2 DVDs, then you have 2 + 85 = 87 DVDs afterwards.
notice that you always take the number of DVDs you already have, and add 85 to it.
d is just a number, but you just don't know it yet. you can change d by any number, and you know d+85 is the number of DVDs afterwards
<u>Question</u>
In the diagram, angle OLM is twice as large as angle PON. What is the size of angle OLM?
Answer:

Step-by-step explanation:
Let Angle PON =x
Therefore: Angle OLM =2x




Therefore:
