Step-by-step explanation:
A/2 = 4
A = 4 x 2
A = 8
I think this should be the answer
Answer:
Number of pineapples = 10
Number of pears = 10 + 9 = 19
Number of kiwis = 10 - 2 = 8
Step-by-step explanation:
Money = $ 13.5
Cost of a pear = $ 0.5
Cost of a pineapple = $ 1.5
Cost of a kiwi = $ 0.3
let the number of pineapple = p
Number of pears = p + 9
Number of kiwis = p - 2
Cost is
0.5 (p + 9) + 0.15 p + 0.3 (p - 2) = 13.5
0.5 p + 4.5 + 0.15 p + 0.3 p - 0.6 = 13.5
0.95 p = 9.6
p = 10
So, number of pineapples = 10
Number of pears = 10 + 9 = 19
Number of kiwis = 10 - 2 = 8

hope this helps
23.72 is greater than 23.697 by 0.023
The circumference of a circle is equal to the diameter times pi. So, let's look at what happens if you double the radius of a circle -- say from 2 to 4. The area will go from 12.56 to 50.24. This means that it has quadrupled.
Answer:
b. circle; 
Step-by-step explanation:
The given conic has equation;
We complete the square to obtain;
This is a circle with center;
This implies that;
When the circle is rotated through an angle of 
,
The new center is obtained using;
and 
We plug in the given angle with x and y values to get;
and 
This gives us;
The equation of the rotated circle is;
Expand;
Multiply through by 4; to get
Write in general form;
Divide through by 2.
