The rumor is spreading to a double amount of people each time and started with only one person.
On the first day, two people knew it. 2¹ = 2
On the second day, four people knew it. 2² = 4
On the third day, eight people knew it. 2³ = 8
On the nth day, the people that will know it = 2ⁿ
Thus, on the eighth day: 2⁸ = 256 people will know it
STEP 1:
Find percentage. 57 out of 100 is the percentage to multiply by.
57/100= 0.57 (= 57%)
STEP 2:
Multiply percentage by the total gallons ordered (24).
=24 gallons * 0.57
=13.68 gallons
ALTERNATIVE METHOD (use which works best for you)
Set up a proportion. 57 to 100 is x out of 24 gallons.
x= number skim gallons to order
57/100= x/24
cross multiply
(57*24)= (100*x)
1368= 100x
divide both sides by 100
13.68 gallons= x
ANSWER: Since you cannot order a partial gallon of milk, round up to 14 whole gallons

Answer: 0.000274 dragon fly per day.
Step-by-step explanation:
First convert the 10 years into days:
10 × 365 = 3650 days.
This means that one dragon fly dies every 3650 days.
Now, to find how many that dies in a day:
1 ÷ 3650 = 0.000274, corrected to three significant figure.
Looks more like a probability question.
Answer:
x>9
Step-by-step explanation:
2x−6>12
Step 1: Add 6 to both sides.
2x−6+6>12+6
2x>18
Step 2: Divide both sides by 2.
2x

20 + 20 + 10 + 25 = 75
75 - 2 = 73
P ( blue for the third selection ) = 20/73
