10,000 * (0.5)^x/19 ; 19.53125
Step-by-step explanation:
Sorry, Im not good at chemistry, but I think this is how you do it.
Part 1: 10,000 * (0.5)^x/19 x=time
Part 2: 10,000 * (0.5)^171/19 = 10,000 *(0.5)^9 = 19.53125

At a bus station, buses begin their routes at 6.Am. The schedule for two of the buses is based on time intervals listen below
Answers
Answer:
They will both leave at 07:15am
Step-by-step explanation:
Given
[tex]Start\ time = 6:00am[/tex]
[tex]Bus\ A=75\ mins[/tex]
[tex]Bus\ B=15\ mins[/tex]
Required
Next time both buses leave the station at the same time
To do this, we list out the multiples of 75 and 15.
We have:
[tex]Bus\ A = 0,75, 150, 225, 300,375, 450, 525, 600 ....[/tex]
[tex]Bus\ B =0, 15,30,45,60,75,90,105,120,135,150,165,180.....[/tex]
After the first departure at 06:00 am (0 minutes) for both buses respectively, the next time they both leave is after 75 minutes (common multiple)
So, the time is:
[tex]Time = 6:00am + 75 mins[/tex]
[tex]Time = 07:15am[/tex]

I need some help finding the volume of a sphere with a diameter of 18.6cm. The website says the answer I got from my calculator was wrong! Help would be greatly appreciated!
Answers
Answer:
V ≈ 3367.6 cm³
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = [tex]\frac{4}{3}[/tex] πr³ ( r is the radius )
Here D = 18.6 , then r = 18.6 ÷ 2 = 9.3 , so
V = [tex]\frac{4}{3}[/tex] × 3.14 × 9.3³
= [tex]\frac{4}{3}[/tex] × 3.14 × 804.357
= [tex]\frac{4(3.14)(804.357)}{3}[/tex]
≈ 3367.6 cm³ ( to the nearest tenth )

Solve log 2x^2 + 2 = 6. Round to the nearest thousandth if necessary.
Answers
Answer:
x = 70.71
Step-by-step explanation:
log 2x² + 2 = 6.
log 2x² + log 100= log 10⁶.
2x² × 100 = 10⁶
2x² = 10⁶/100
2x² = 10⁴
x² = 10⁴/2
x² = 5000
x = √5000
x is approximately 70.71
x = 70.71

Luna Lovegood is making smoothies for the Ravenclaw students. She combines two and a half quarts of orange juice, four and a half pints of milk, and 5 cups of pineapple juice to make the smoothies. How many cups of smoothie does Luna make? *
Answers
Answer: Luna Lovegood made 24 cups of smoothie.
Step-by-step explanation: We have to convert the measurements to cups.
Orange Juice:
2 1/2 quarts converted to cups is 10 cups.
2 1/2 or 2.5 multiplied by 4 equals to 10
Milk:
4 1/2 or 4.5 pints converted to cups is 9 cups.
You have to do 4.5 times 2 to get 9.
Pineapple Juice:
5 cups. Since it's already been converted we don't do anything to convert.
Lastly, we add.
10+9+5=24 cups.
Answer:
Let me go ask LunaLovegood555..... she's good at making smoothies.

Find:
Volume of cuboid
Surface area of cuboid
Computation:
Volume of cuboid = [L][B][H]
Volume of cuboid = [10][5][6]
Volume of cuboid = 300 in³
Surface area of cuboid = 2[lb][bh][hl]
Surface area of cuboid = 2[(10)(5) + (5)(6) + (6)(10)]
Surface area of cuboid = 2[50 + 30 + 60]
Surface area of cuboid = 2[140]

Answer:
82.7kg
Step-by-step explanation:
wdym by immersive reader?
Answer:
82.7kg
Step-by-step explanation:
We know that Susan is 40.65kg. If Adam weighs 4.3kg more than Susan, it means that he weighs 40.65+4.3 = 44.95kg
James is 2.9kg lighter meaning he is 40.65-2.9 = 37.75kg
Now that we know that weights of Adam and James (44.95 and 37.75). we can add them together to get the combined weight: 44.95 + 37.75 = 82.7kg

After rain, water flows over the Sutherland Falls at a rate of 74240 litres per second. This is an increase of 45% on the rate before the rain. Calculate the rate before the rain.
Answers
Answer: 51,200 litres per second
Step-by-step explanation:
Assume that the rate before the rain is denoted as x.
This would mean that 74,240 liters per second is an increase of 45% over the value of x.
In formula form therefore this is:
74,240 = x + (x * 45%)
74,240 = x + 0.45x
74,240 = 1.45x
x = 74,240 / 1.45
x = 51,200 litres per second
