Answer:
3/4
Step-by-step explanation:
a1 = (-1/3)^0 = 1
r = -1/3
Hence S = 1/(1+1/3) = 1/(4/3) = 3/4
Answer:
9 and 3
Step-by-step explanation:
Let the first number be x and second number be y hence their sum
x+y=12 ......(1)
Making x the subject theb x=12-y
Three times be first number is 3x
3x-y=24.......(2)
Adding the two sets of equations then
4x=36
X=36/4=9
The second number will be 12-9=3
So the first number is 9 and second is 3
One measure = 2* 6 = 12 ft^2
other = 2.5 * 4 = 10 ft^2
total are = 22 fT^2
total cost = 22 * 42 = $924
Answer:
x² + 12
Step-by-step explanation:
note 2 days = 48 hours
divide amount of water by 48 for hourly rate, that is
= 
+ 
= x² + 12
C = 2(pi)r....so we are looking for the radius (r)
42 = 2 * 3.14 * r
42 = 6.28r
42/6.28 = r
6.69 = r <===
