write 819 in base five
819 in base five is equal to 13134.
Define base five.Base five is a positional numeral system used in mathematics, having 5 as its base or radix. This means that it represents any real number using five different symbols, often the digits 0, 1, 2, 3, and 4. The ones place is represented by the digit on the right, the place of the five by the digit to the left, the twenty-fives place by the digit after that, and so on. Each digit in base five represents a multiple of a power of five.
To write 819 in base five:
Find the largest power of 5 that is less than or equal to 819: 5^4 = 625.Divide 819 by 625 to find how many 5^4's are in 819: 819 / 625 = 1 with a remainder of 194.Write down the result (1) in the 5^4 place (leftmost digit).Repeat steps 1-3 with the remainder (194):
5^3 = 125194 / 125 = 1 with a remainder of 69Write down the result (1) in the 5^3 place (second digit from left).Repeat steps 1-3 with the remainder (69):
5^2 = 2569 / 25 = 2 with a remainder of 19Write down the result (2) in the 5^2 place (third digit from left).Repeat steps 1-3 with the remainder (19):
5^1 = 519 / 5 = 3 with a remainder of 4Write down the result (3) in the 5^1 place (second digit from right).The remainder (4) is less than 5, so write it down in the 5^0 place (rightmost digit).
Combine all the digits: 13134.
Therefore, 819 in base five is equal to 13134.

Therefore, the simplest form of 2p x 3q x 5r is 30pqr
This morning, Kendall drank a cup of coffee that had 95 milligrams of caffeine in it. She didn't have any more caffeine for the rest of the day. Kendall read online that the amount of caffeine in her body will decrease by approximately 13% each hour. Write an exponential equation in the form y=a(b)x that can model the amount of caffeine, y, in Kendall's body x hours after drinking the coffee. Use whole numbers, decimals, or simplified fractions for the values of a and b. y = ____. To the nearest milligram, how much caffeine will be in Kendall's body after 12 hours?
An exponential equation in the form \(y=a(b)^x\) that can model the amount of caffeine, y, in Kendall's body x hours after drinking the coffee is
The amount of caffeine that will be in Kendall's body after 12 hours is 18 milligrams.
What is an exponential function?In Mathematics, an exponential function can be modeled by using the following mathematical equation:
f(x) = a(b)^x
Where:
a represents the initial value or y-intercept.x represents time.b represents the rate of change.Since Kendall drank a cup of coffee that had 95 milligrams of caffeine which is decreasing at a rate of 5% per day, this ultimately implies that the relationship is geometric and the rate of change (decay rate) is given by:
Rate of change (decay rate) = 100 - 13 = 87% = 0.87.
By substituting the parameters into the exponential equation, we have the following;
\(f(x) = 95(0.87)^x\)
When x = 12, we have;
\(f(12) = 95(0.87)^{12}\)
f(12) = 17.86 ≈ 18 milligrams.

Part A: James bought a cake that weighs pounds. How many ounces does the cake weigh? Show your work. (5 points)
[16 ounces = 1 pound]
Part B: A running tap dispenses 0.15 gallons of water every second. How many pints of water is dispensed after 20 seconds? Show your work. (5 points)
[1 gallon = 4 quarts, 1 quart = 2 pints]
Question 4 options:
Answer:
For part a multiply the pound amount by 16. Your work would look something like this... (not actual answer) 10 pounds x 16= 160 ounces. So 10 pounds= 160 ounces!
For part B
0.15 gallons=1.2 pints
Example: .15 x 4= .6
.6 x 2= 1.2 pints
1.2 x 20 seconds= 24 pints!
Hope this helps
Step-by-step explanation:
:)
Answer:
Part A: 52 oz
Part B: 24 pints
Step-by-step explanation:
Part A:
Since 1 pound = 16 ounces, the number of ounces is 16 times the number of pounds. To convert pounds to ounces, multiply the pounds by 16.
3 1/4 lb × 16 oz/lb =
= 13/4 × 16 oz
= 13 × 4 oz
= 52 oz
Answer: 52 oz
Part B:
We need to convert from gallons to pints.
1 gallon = 4 quarts
1 quart = 2 pints
That means that 1 gallon = 8 pints.
0.15 gallon/second × 8 pints/gallon =
= 1.2 pints/second
The tap dispenses 1.2 pints/second.
Now we calculate the number of pints dispensed in 20 seconds.
1.2 pints/second × 20 seconds = 24 pints
Answer: 24 pints

In order to calculate this, we can use the following formula:
\(\boxed{\bold{FV = PV(1 + \frac{r}{n})^{nt}}}\)
Where:
FV = Future Value PV = Present Value r = Annual interest rate n = Number of times interest is compounded per year t = Number of yearsIn this case, the following values would be used:
FV = ?PV = $3,294 r = 15%=0.15 n = 4t = 12Plugging these values into the formula, we get:
\(FV = 3,294(1 + \frac{0.15}{4})^{4*12}\)
= $19,282.025

In order to calculate this, we can use the following formula:
\(\boxed{\bold{FV = PVe^{rt}}}\)
Where:
FV = Future Value PV = Present Value r = Annual interest rate t = Number of yearsIn this case, the following values would be used:
FV = ?PV = $2,580r = 3%=0.03t = 12value of e= 2.7183Plugging these values into the formula, we get:

Precal please help me
Answer:
a) 910
b) 1183
c) False
take these answers with a grain of salt, i cant guarantee accuracy but the process should be right?
Step-by-step explanation:
a)
Starting with 1300 dollars, we are given that the stock loses 30% of its value.
This means that we take 70% of 1300 as it is now at 70% of its value. This gives us 910.
b)
At 910 dollars, we are told that the stock's value rises by 30%, so if we multiply 910 by 1.3 or 130%, we get 1183. At this time, the stock is now worth 1183 dollars.
c)
It is false, as can be seen above a 30% loss followed by a 30% gain results in 91% of the original price. That's a 9% net loss.
This can be seen using variables, x -> 0.7x -> 0.7*1.3 x -> 0.91 x
Jason owns a cabin that he rents to people for a maximum of 21 nights. He uses the function f(x) = 175x + 50 to calculate the rental cost for nightsWhat is the domain for the function in this context?
Answer:
domain: all natural numbers greater than zero and less than or equal to 21

You cannot go for zero nights, and the maximum number of nights you can stay is 21. You also cannot have fractional night, so your answer has to be in natural numbers.
6x ( 2/3 divided by 2)+ 0.5
Answer:
2.5
Step-by-step explanation:
Given expression:
\(6 \times \left(\dfrac{2}{3} \div 2\right)+0.5\)
Following the order of operations (PEDMAS), carry out the calculation inside the parentheses first.
When dividing a fraction by a whole number, first covert the whole number into a fraction:
\(\implies 6 \times \left(\dfrac{2}{3} \div \dfrac{2}{1}\right)+0.5\)
When dividing fractions, flip the second fraction (swap the numerator and denominator), then multiply:
\(\implies 6 \times \left(\dfrac{2}{3} \times \dfrac{1}{2}\right)+0.5\)
\(\implies 6 \times \left(\dfrac{2 \times 1}{3\times2}\right)+0.5\)
\(\implies 6 \times \left(\dfrac{2}{6}\right)+0.5\)
\(\implies 6 \times \dfrac{2}{6}+0.5\)
Now carry out the multiplication:
\(\implies \dfrac{6 \times2}{6}+0.5\)
\(\implies \dfrac{\diagup\!\!\!\!6 \times2}{\diagup\!\!\!\!6}+0.5\)
\(\implies 2+0.5\)
Finally carry out the addition:
\(\implies 2.5\)
2.5
6*(2/3)/2 + 0.5
6*1/3 + 0.5
2 + 0.5
=2.5

Use the graph of f(x) to find the solutions to the equation f(x)=0.
Answer:
x = -4, 7
Step-by-step explanation:
Pre-SolvingWe are given the graph of the function f(x), and we want to find the values that make the statement f(x) = 0.
f(x) = 0 means that there are certain values that make the value of f(x) (which can be considered as y) equal to 0.
SolvingWe can look to the graph to help us - we should look at where y is equal to 0, which is the x-axis.
On the x-axis, we can see that the function passes through both -4 and 7 (the graph goes up by 1) on that line.
As coordinate points, they are written as (-4,0) and (7,0).This means that when either -4 or 7 are substituted into the function (i.e. when they are equal to x), they will make the function equal 0.
So, it means that x = -4, 7.

5/8 entre 6 personas
Based on the information we can infer that 5/8 between 6 people is equal to 15/24.
How to divide 5/8 between 6 people?To calculate the part that corresponds to each person, divide the fraction 5/8 by the number of people, which in this case is 6. To simplify the fraction, you can reduce the numerator and denominator by dividing both by their maximum common factor, which is 3.
5 ÷ 3 = 1 and 2 remainder8 ÷ 3 = 2 and 2 remainder
So the fraction can be simplified to 1 2/8, which can also be expressed as 1 1/4 or 5/4 in its most simplified form. This means that each person would receive 5/4 of the original share, and since there are 6 people in total, you can multiply 5/4 by 6 to get the total share that corresponds to all 6 people:
(5/4) x 6 = 30/4 = 15/2 = 15/24
So each person would receive 15/24 of the original amount.
