Answer:
24 meters
Step-by-step explanation:
The area of a circle can be found using the following formula.
We know that the area is 144pi m^2.
Substitute 144pi m^2 in for a.
We want to find the diameter. First, we must find the radius. We have to get the variable, r, by itself.
Divide both sides of the equation by pi.
The variable, r , is being squared. The inverse of a square is the square root. Take the square root of both sides of the equation.
The radius of the circle is 12 meters, but the question asks for diameter. The diameter is twice the radius.
The radius is 12 m.
Multiply
The diameter of the circle is 24 meters.
Step-by-step explanation:
2 x 2= 4, no. of 2s= 2
2 x 2 x 2= 8, no. of 2s= 3
2 x 2 x 2 x 2= 16, no. of 2s= 4
2 x 2 x 2 x 2 x 2= 32, no. of 2s= 5

Answer:
Answer is 904
Refer below.
Step-by-step explanation:
5650 total,
And 4:1 which adds up and make 5. So,
5x = 5650
x=5650/5
x=1130
As pichard part is 4:1 so his part is 4 overall the money so,
Richard got 4x = 4 × 1130 = 4520
4520 now dividing in 6:3:1
10a = 4520
A= 452
Wife amount is 3a = 3 ×452 = 1356
Son is 1a so its,
Son = 452
Minus= 1356 -452 = 904
Wife got 904 more than son
A composite number is a number divisible by numbers other than 1 and itself
Mutiply first equation by -1 and add to 2nd
-y=3x-6
<u>y=x^2-4 +</u>
0=x^2+3x-10
factor like any equation
what 2 numbers multiply to -10 and add to 3
-2 and 5
0=(x-2)(x+5)
set to zero
x-2=0
x=2
x+5=0
x=-5
solve for y in each case
for x=2
y=2^2-4
y=4-4
y=0
(2,0) is a point
for x=-5
y=(-5)^2-4
y=25-4
y=21
(-5,21) is another
the solutions are
(2,0) and
(-5,21)
