A bacteria that starts with 3 cells increases by 15% every hour.
Write an exponential growth equation that models the situation
How many bacteria cells will there be in 13 hours?
Answer:
Step-by-step explanation:
In order to determine the equation, consider that any exponential growth equation can be written as follow:
[tex]f(t)=A(1+r)^t[/tex]
where,
f(t): amount of bacteria after t hours
A: initial amount of bacteria = 3
r: growth rate in decimal form = 0.15 (15%)
t: time in hours
By replacing the previous values into the expression for f(t) you get;
[tex]f(t)=3(1+0.15)^t\\f(t)=3(1.15)^t[/tex]
Hence, the answer is f(t) = 3(1.15)^t
Now, replace t = 13 to determine the amount of bacteria after 13 hours:
[tex]f(13)=3(1.15)^13\\f(13)=18.46[/tex]
Hence, after 13 hours there are approximately 18 bacteria

Given the proportional table, what is the missing value?
PLeaseeee helppp!! Math: percentages. will make BRAINLY
Answer: 840
Step-by-step explanation: 50% is half. All I did was add 420 two time since 420 is half of what this person has to spend.
Answer:
the answer should be 210 dollars because first of all remember that when we are dealing with this problems of percents we need to divide first the percent which is 50% by 100 and you will get 0.50 so then you multiplied it.
0.50 times 420= 210
210 is the correct answer and have a great day.

In the game 'rock, paper, scissors', both players make a fist with one hand. On the count of three, the players make either a rock (by keeping their hand in a fist), a sheet of paper (by holding their hand out flat), or a pair of scissors (by sticking out their first two fingers).
If both players make the same thing, it's a tie. If a rock and scissors are played, the rock wins. If scissors and paper are played, the scissors win. If paper and a rock are played, the paper wins.
a) Play at least 20 games of 'rock, paper, scissors' with a friend. Record the results as you go - write down who won, and what with.
b) After you've finished playing, organise your results into a table and use this to estimate some probabilities. Who was most likely to win? Were either of you more likely to play a certain object each time? Could you use this information to help you win more games next time?
If this is for a school assignment, not sure how someone else would record themselves playing rock paper scissors.

Circle Q has center (10,10) and a radius of 2. Circle Q' is formed by dilating Circle Q by a factor of 1/2, which statement is true?
I NEED HELP ASAPPPP PLSS!!!!
Answer:
(a) Describe the rule for translating center Q onto center P.
center P(2, 0)
center Q(0, 4)
you would need to add 2 units in x axis, and subtract 4 units on y axis.
(b) Determine the scale factor for dilating circle Q so that it has the same radius as circle P.
P radius 20, Q radius 2, radiusQ*10 = radiusP, so the scale factor is 10
(c) Are circles P and Q similar? Explain your answer.
they are similar because a similarity transformation (translation, dilation) exists between them
Step-by-step explanation:
Circle Q' is formed by dilating Circle Q by a factor of 10.
What is the scale factor?The ratio between comparable measurements of an item and a representation of that thing is known as a scale factor in arithmetic.
To Describe the rule for translating center Q onto center P.
center P(2, 0) and center Q(0, 4)
We would need to add 2 units on x-axis, and subtract 4 units on y-axis.
To find the scale factor for dilating circle Q ,so that it has the same radius as circle P.
P radius 20, Q radius 2, radius Q x 10 = radius P, so the scale factor is 10
It is found that they are similar because a similarity transformation (translation, dilation) exists between them.

What is the distance around the circle?
314 feet
20 feet
31.4 feet
62.8 feet
Answer:
62.8 feet
Step-by-step explanation:
The distance around the circle is known as the circumference
We can find the circumference using the formula C = 2πr
Where r = radius
The radius is a line that goes from the center of the circle to any point on the circle.
Here, we are given that the radius is 10 feet
Plugging in the value of the radius into the circumference formula
Again we have C = 2πr
==> plug in r = 10
C = 2π(10)
==> multiply 10 and 2
C = 20π
==> multiply 20 and π (which has a value of about 3.14)
C = 62.8 ( rounded )
So the distance around the circle is about 62.8 feet.

Answer:
62.8 feet
Step-by-step explanation:
We are given:
[tex]\text{Radius of circle} = \bold{10} \ \bold{feet}[/tex]
Definition of radius: The radius of the circle is the line that starts from the center point and ends at any point of the circle.
The formula that expresses the circumference of a circle is 2πr. [Where "r" represents the radius of the circle]
Let's substitute the radius in the circumference formula and simplify it to determine the distance around the circle (circumference).
[tex]\implies \text{Circumference of circle} = 2\pi r[/tex]
[tex]\implies \text{Circumference of circle}= 2\pi (10)[/tex] [tex]\implies \text{Circumference of circle} = 20\pi[/tex]
Let us take π as 3.14. Then, we get:
[tex]\implies \text{Circumference of circle} = 20(3.14) = 2(31.4) = \boxed{62.8 \ \text{feet}}[/tex]
Therefore, the distance around the circle (circumference) is 62.8 feet.

The diagonal of square A, marked off by the red stars, is where the concession stand is. A local high school band is performing at the outdoor theater on a summer evening. The band has a school banner that is 40-feet long, and band members would like to hang it across the concession stand to let people know they are performing. Estimate the length of the concession stand to determine if the school banner can fit across the length of the concession stand. Show your work and explain your reasoning.
Answer:
The school banner can fit across the length of the concession stand
Step-by-step explanation:
The following information is missing:
The length if the sides: c is 50 feet long, b is 40 foot long, and a is 30-foot long.
The distance between the two red stars of the picture makes the hypotenuse of a right triangle, where two sides of length a (30 ft) are the legs. From Pythagorean theorem, diagonal of quare A is:
diagonal² = 30² + 30²
diagonal = √1800 = 42.43 ft
which is longer than the banner.
The school banner can fit across the length of the concession stand is 42.43 ft.
What is Diagonal of Square?The line stretching from one corner of the square or rectangle to the opposite corner through the center of the figure is known as the diagonal. Any square that has two diagonals are equal in length to each other.

A parallelogram has an area of 120 square feet and a height of 6 feet.
What is the length of the base of the parallelogram?
Enter your answer in the box.
*box*
Answer:
20 feet
Step-by-step explanation:
1. We know from here that A = bh (Area = Base x Height).
We are given:
A = 120 ft^2
h = 6 ft
b = ?
2. Let's rearrange our formula (A = bh) so that we find what "b" equals."
Our new formula will be: b = A/h (base = Area / height).
3. Let's apply it to the question and do the required math!
b = A/h
b = 120/6
b = 20 ft
Answer:
b = 20 ft
Step-by-step explanation:
The area of a parallelogram is given by:
A = b*h
where,
A: area = 120 ft^2
b: base = ?
h: height = 6 ft
From the equation for A, solve for b, replace the values of A and h and simplify:
b = A/h
b = 120ft^2/6ft
b = 20ft
Hence, the length of the base of the parallelogram is 20 ft

B.

C.
8

D.
15
Answer:
15
Step-by-step explanation:
60/4 which is the chance it gets out of being drawn
Using the concept of probability, the reasonable prediction for the number of times a purple marble will be drawn is 12 times (option A).
What is a reasonable prediction for the number of times a purple marble will be drawn?To predict the number of times a purple marble will be drawn, we can use the concept of probability. The probability of drawing a purple marble in a single draw is the number of purple marbles (4) divided by the total number of marbles (5 + 6 + 3 + 2 + 4 = 20).
Probability of drawing a purple marble = 4 / 20 = 1/5
Since the student makes a total of 60 draws and each draw is independent (the marble is returned to the bag after each draw), we can use the concept of expected value to predict the number of times a purple marble will be drawn.
Expected value = Total number of draws × Probability of drawing a purple marble
Expected number of times a purple marble will be drawn = 60 × (1/5) = 12
