At the peak of the hyperinflation prices for the 16000 per cent per month at this rate by what percentage would prices have risen in one year? In one day?
The prices would have risen a total of 192000% in one year.
Calculation of hyperinflation rateThe percentage rate of inflation is = 16000% per month
Therefore for one year is

alA, C, E would all be correct
Step-by-step explanation:
the explanation is quite simple just put them all together they all come out to 280.
Answer:
A, C, E
Step-by-step explanation:
If we separate 35 into tens and units then:
8 × 35 = 8 × (30 + 5)
We can use the distributive property to expand the above:
8 × (30 + 5) = (8 × 30) + (8 × 5)
We can also separate 35 into 20 + 15:
8 × 35 = 8 × (20 + 15)
Therefore, the expressions that are equal to 8 × 35 are A, C and E
Two cards are drawn without replacement from a standard deck of 52 playing cards. What is the probability of choosing a face card for the second card drawn, if the first card, drawn without replacement, was a king? Express your answer as a fraction or a decimal number rounded to four decimal places.
The decimal value is approximate.
==========================================================
Explanation:
The face cards are Jack, Queen, King.
We have 3 face cards for each suit, and 4 suits, giving 3*4 = 12 face cards out of a 52 card deck.
The first card is a king, which is not put back. This means have 12-1 = 11 face cards left out of 52-1 = 51 cards left.
The probability of getting another face card is 11/51 = 0.2157 approximately
This is about a 21.57% chance
Note: if the first card was put back, or replaced with an equal copy, then the answer would be 12/52 = 3/13 = 0.2308 = 23.08%
Answer:
The probability of choosing a face card for the second card drawn if the first card was a king, drawn without replacement, is 11/663 or .0166.
Step-by-step explanation:
There are 52 cards and 12 of these are face cards.
The probability of drawing a king for the first card is the number of kings divided by the total number of cards:
4/52The probability of drawing a face card after the first card was drawn without replacement is:
11/51When we take the king card out of the deck, we remove 1 from both the denominator and the numerator since it is also a face card.Since these events are dependent (drawing without replacement), we can use this basic probability formula:
[tex]P(A \cap B)=P(A) \cdot P(B)[/tex]This formula tells us the probability of first drawing the king card, then drawing a face card afterward since 2 cards are being drawn. We must calculate the probability of both of these events occurring one after the other.
P(A) refers to the probability of getting a king on the first draw, 4/52, and P(B) refers to the probability of getting a face card on the second draw, 11/51.
Let's multiply these probabilities together.
[tex]\displaystyle \frac{4}{52} \cdot \frac{11}{51} =\frac{11}{663}=.0166[/tex]The probability of choosing a face card for the second card drawn, if the first card drawn without replacement was a king, is 11/663 or .0166.

Answer:
y=[tex]\frac{2}{3}x[/tex]+4
Step-by-step explanation:
[tex]\frac{rise}{run}[/tex]

The required equation in slope-intercept form is y = - [tex]\frac{2}{3}[/tex]x + 4
What is an equation?An equation represents any two expressions or statements are equal that means they are having an equal to (=) sign in brtween them.
What is slope intercept form?The equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept is called slope-intercept form of the equation.
How to find the slope ?Slope of a line is the inclination of the straight line towards x axis.
If a straight line passes through two points (a , b) and (c , d), then slope(m) of the straight line can be calculated by the formula,[tex]m = \frac{d - b}{c-a}[/tex]
According to the problem, the straight line passes through (6 , 0) , (3 , 2) , (0, 4) , (-3 , 6).
Slope (m) = [tex]\frac{2-0}{3-6}[/tex] = - [tex]\frac{2}{3}[/tex]
How to write the equation in slope-intercept form?The equation can be written as
y = - [tex]\frac{2}{3}[/tex]x + b
Now , this line passes thorugh (0,4). So, (0,4) will satisfy the equation∴ putting (0,4) in the equation, we get,
y = 4
∴ The required equation is y = - [tex]\frac{2}{3}[/tex]x + 4.
For check we can satisfy the point ( -3 , 6) in the equation.- [tex]\frac{2}{3}[/tex](-3) + 4 = 6
CLearly, the point satisfies the equation.

A $249 video game system is
discounted 15%. With 6%
sales tax, what would be the
final price of the system?
Answer:
$224.35
Step-by-step explanation:
The game is originally $249.
It's discounted by 15%, meaning it went down by 15%. 100% - 15% = 85%, so the new price is 85% of what it was before.
The sales tax is 6%, meaning the final price goes up by 6%. This means it would be 106% of what it was before.
85% = 0.85 of something
106% = 1.06 of something
[tex]249 \times 0.85 \times 1.06 = 224.349[/tex]
Now, we just round it to the nearest cent, which would give us $224.35

The easiest way to do this would be,
-165 + 65 = -100 than -100 + 3217
-100 + 3217 is the same as 3217 - 100
-100 + 3217 = 3,117
11b. 173 + (-43) + (-97)
this is the same as 173 - 43 - 97

we have 23 marbles: 6 red marbles, 5 green marbles, 3 blue marbles, and 9 yellow marbles. We are drawing one marble from the bag. What is the probability of drawing a red or a yellow marble?
Answer:
15/23
Step-by-step explanation:
What is probability?
Probability in simple terms is the likelihood of something happening.
We can say that probability = # of favorable outcomes ( what we want to happen ) / total # of outcomes ( simply what's expected to happen )
Here, we want to find the probability of drawing a red or yellow marble.
So # of favorable outcomes = drawing a red or yellow marble and total # of possible outcomes would be simply the total number of marbles
Given:
There are 23 marbles totalThere are 9 yellow marbles There are 6 red marblesGiven this we can determine what the # of favorable outcomes are as well as how many total marbles are.
So in total there are 23 marbles, so total number of outcomes = 23
And there are 6 red marbles and 9 yellow marbles, so number of favorable outcomes = 6 + 9 = 15
Plugging these values into the probability formula we get 15/23
So the probability of drawing a red or yellow marble would be 15/23
Answer:
P(red or yellow marble)= 15/23
Step-by-step explanation:
If we have 23 marbles in the bag, 6 red and 9 yellow, we add the 6 and 9 to get 15. So there are 15 marbles that are red/yellow out of the 23 in the bag. This means the probability is 15/23. Hope this helps <3

Write an equation of the line that passes through the point (6,-9) with the given slope m= 3
Answer:
y = 3x - 27
Step-by-step explanation:
Since the slope is three, that is the only one that can be the answer.
answer: y = 3x - 27
explanation:
equation of a straight line: y = mx + c
( m is the slope and c the y- intercept )
here m = 3 , then y = 3x + c ← is the partial equation
to find c substitute (6, - 9) into the partial equation
-9 = 18 + c ⇒ c = -9 - 18 = - 27
y = 3x - 27 ← equation of line

To Find:

Solve:
Since we know that:
A package of five tickets costs $74.45.
Individual tickets cost $17.25 each.
Hence we know that 5 + 3 = 8
Thus,
$74.45 = 5 tickets
Now for the 3 tickets we can do individual tickets which cost $17.25
$17.25 × 3 = 51.75
Then we add both together:
51.75 + 74.45 = $126.20

⇒ The sum of the lengths of any two sides in a triangle is always greater than the length of the third side in the triangle.
⇒ The differnce of the lengths of any two sides in a triangle is always lesser than the length of the third side in the triangle.
⇒ The difference between 4cm and 7cm is
3cm and their sum is 11cm.
⇒ To ensure that the above mentioned rule is not violated, the possible length of the third side has got to be greater than 3cm and lesser than 11cm.
⇒ So from the given options 6cm is less than
