Slope = (9 + 3)/(-1 + 2) = 12/1 = 12
answer
12
Answer:
21.6 liters
Step-by-step explanation:
40 drops make up a volume of 10 mL
Therefore, the volume of 1 drop of water = 10mL/40 = 1/4 mL= 0.25mL
Since the tap loses 1 drop of water in 1 sec, it loses 0.25mL of water in 1 second
60 seconds make up 1 second so volume of water lost in 1 minute = 0.25 x 60 = 15 mL
60 minutes make up 1 hour so volume of water lost in 1 hour = 15 x 60 = 900 mL
24 hours make up a day so volume of water lost in 1 day = 900 x 24 = 21,600 mL
Since 1000 mL make up 1 liter, divide by 1000 to get volume in liters
Volume of water lost in 1 day = 21600/1000 = 21.6 liters
Can be done as one equation
V lost in one day = 0.25 x 3600 x 24 mL = 21600 mL = 21.6 L
5(8x-2)=270
distribute the 5 into 8x-2
5*8x-5*2=270
you get
40x-10=270
combine like terms
40x=280
divide both sides by 40 to find x
x=7
Answer:
2.25 dollars per pound
Step-by-step explanation:
Take the cost and divide by the number of pounds
11.25 dollars / 5 pounds
2.25 dollars per pound
Answer:
Step-by-step explanation:
v = 3 (r - 1)
v = 3(- 1 - 3) <----- Here we are substituting R
v = -3 - 9 <---- Here we expanded the bracket
v = -12 <--- This is your answer, because -3 -9 is equal to -12
