Answer:
$204.85
Step-by-step explanation:
Let the two legs be the adjacent and the opposite of the right triangle. To get the third side (the hypotenuse), we will use the pythagoras theorem;

Perimeter of the garden will be the sum of all the three sides.
Perimeter of the garden = 12 + 12 + 16.97
Perimeter of the garden = 40.97 feet
Since 1 foot = $5
40.97 feet = x
Cross multiply
1*x = 5*40.97
x = 204.85
Hence it will cost $204.85 to fence the entire perimeter of the garden
Range is the largest number minus the smallest.
210 - 68 = 142
142 is the range.
Solve for c is what we must do.
A = b + cd
A - b = cd
(A - b)/d = c
Done.
Answer:
18=18
Step-by-step explanation:
a=90-b
a=50 mL at 4%
b=40 mL at 40%
check
0.04*50+0.4*40=0.2*90
2+16=18
18=18
