Answer:
6.76 m^2
Step-by-step explanation:
Large circle area = pi r^2 = pi L^2 = 60.84
then L = sqrt (60.84/pi)
Small circle radius = r = 1/3 L
small circle area = pi r^2
= pi ( 1/3 sqrt (60.84/pi))^2 = 6.76 m^2
12 x 8= 96
10 x 8 =80
12 × 10= 120
120+80+96= 296
Answer:
5x-4y = -32
Step-by-step explanation:
First write the equation in point slope form
y-y1 = m(x-x1)
y - -2 = 5/4 ( x- -8)
y+2 = 5/4 (x+8)
Multiply each side by 4 to clear the fraction
4( y+2 )= 4*5/4 (x+8)
4y +8 = 5(x+8)
4y+8 = 5x+40
Subtract 4y from each side
8 = 5x-4y +40
Subtract 40 from each side
-32 = 5x-4y
5x-4y = -32
Answer:
The system has one solution.
Step-by-step explanation:
We have two equations:
y = -2x - 4
y = 3x + 3
Equalling them:
y = y
-2x - 4 = 3x + 3
5x = -7
And
Replacing in the other equation we should get the same result.
So the system has one solution.
