Answer:
[tex]P(t)=37\cdot 4^{t/9.1}[/tex]
Step-by-step explanation:
The number of people who receive the email increases by a factor of 4 every 9.1 weeks.
This is an exponential growth of the form:
[tex]A=A_o(r)^{t/k}[/tex]
Where:
[tex]A_o =$Initial value\\r=Growth rate\\k=Growth Period\\t=time[/tex]
In this case:
[tex]A_o =37\\r=4\\k=9.1\:weeks[/tex]
Therefore at any time t, the function describing this scenario is:
[tex]P(t)=37\cdot 4^{t/9.1}[/tex] where t is in weeks.
Consider the tables.

Joe wants to buy a skateboard but he doesn't know if he has enough money. The price of the skateboard is $85 and the sales tax is 6%. What will be the total cost of the skateboard?
Answer:
$90.10
Step-by-step explanation:
price of the skateboard = $85
sales tax = 6%
Dollar value of sales tax = 6% of price of the skateboard
= 6% of $85 = (6/100) * $85 = ( 6* 85)/100 = $ 5.10
Total cost of the skateboard = price of the skateboard + sales tax value
substituting the value of price of the skateboard and sales tax value, calculated above, we have
Total cost of the skateboard = $85 + $ 5.10 = $90.10
A bag contains 40 marbles. 8 are green and 2 are blue. You select one marble at random. What is the probability the marble is not green or blue? P(green
or blue)
0.2
0.02
0.75
0.25
Answer:
0.75
Step-by-step explanation:
its 0.75 because when you divide 40/ the total of the blue and green marbels it equals 0.75
Answer:
0.75
Step-by-step explanation:
8 + 2 = 10.In total there are 40.So that makes it 3/4.1/2 is 20.Add 1/4 and you get 3/4 or 75%.When you add 1/4 you are adding 10 to 20.That gives you 30 or 75 % of 40.

We are planning a reception for our daughter. The hall that we are renting charges a $50 cleanup fee. In addition to the cleanup fee, they charge $33 per guest for food and drinks.
If we have $3,300.00 available, what is the maximum number of guest we can invite without going over our budget?
Answer:
98 guests
Step-by-step explanation:
First, you would take the amount of money available, $3,300.00, and subtract the cleanup fee ($50) from that.
You would get $3,250
Next, you divide $3,250 by the amount of money per guest ($33).
Your total is 98.48 repeated
That rounds to 98 people, since you can't go over.
Hope this helps you!

Six words have 2 vowels and 2 consonants .How many letters are there in 6 words?How many vowels consonants
Answer:
24, 12, 12
Step-by-step explanation:
I do not understand the question, but I believe you gave us how many vowels and consonants are in a word. Then you asked us for how many of them were in 6 words, which is simple math of 4 times 6. I don't get the last part, but I think you asked how many consonants in 6 words, and how many vowels in six words, another simple math question, 2 times 6.
In the English language, 5 letters are typically considered vowels: a, e, i, o, and u, with 2 additional letters, y, and w, that can sometimes act as vowels or consonants depending on their position in a word. To find out how many vowels and consonants there are in six words, we need more information about the specific six words.
Explanation:In the English language, 5 letters are typically considered vowels: a, e, i, o, and u. However, there are 2 additional letters, y, and w, that can sometimes act as vowels or consonants depending on their position in a word.
To find out how many vowels and consonants there are in six words, we need more information about the specific six words. If each of the six words has 2 vowels and 2 consonants, then the total number of letters in the six words would be 6 x (2 + 2) = 24.
Lines s, t, u, and v are cut by transversal r. Clockwise from top left, the angles formed by r and s are blank, 89 degrees, blank, blank; formed by r and t are 89 degrees, blank, blank, blank; formed by r and u are 91 degrees, blank, blank, blank; formed by r and v are blank, 89 degrees, blank blank , Which lists all the lines that are parallel to line s? only line v
only line t and line v
only line u and line v
only lines t, u, and v
By using the congruent angle relationships formed by transversal cutting parallel lines, we can infer that only lines t and v are parallel to line s, as they form corresponding angles of 89 degrees with transversal r, unlike line u, which forms a 91-degree angle.
The information given in the question indicates that a transversal r cuts four lines s, t, u, and v. By the information given for the angles formed by this transversal with each line, we can determine which lines are parallel to line s using the concept of alternate interior angles and corresponding angles, which are congruent if the lines are parallel Since the angle formed by the transversal and line s is 89 degrees and a corresponding angle formed by the transversal and line t is also 89 degrees, we can say that line s is parallel to line t.
Similarly, since another angle formed by transversal and line v is also 89 degrees, it implies that line s is also parallel to line v. However, line u has an angle of 91 degrees formed by the transversal, which does not match the 89-degree angle formed by the transversal with line s, indicating that line u is not parallel to line s. Given this information, the lines parallel to line s are only line t and line v.

Below is the graph of equation y= |x+2|-1. Use this graph to find all values of x such that...
y<0
To find the values of x such that y is less than 0 in the equation y = |x + 2| - 1, we set y less than 0 and solve for x. The values of x that satisfy y < 0 are x < -1.
Explanation:To find the values of x such that y is less than 0, we need to determine the portion of the graph below the x-axis, since y is negative in that region. Given the equation y = |x + 2| - 1, we can set y less than 0 and solve for x.
Setting y = 0, we have 0 = |x + 2| - 1. Adding 1 to both sides, we get 1 = |x + 2|. When the expression inside the absolute value is positive, the absolute value will be the same. Therefore, we can write x + 2 = 1. Solving for x, we get x = -1.
So, the values of x such that y is less than 0 are x < -1.

Answer:
x= (-3i-√3)/2
x= (3i+√3)/2
Step-by-step explanation:
you have to use the quadratic formula which is (-b±√b^2+4ac)/2(a)
a=1
b=3
c= -3
when you plug the numbers into the formula, you get a negative in the square root, so you have to bring out an Imaginary number which is i and connect it with your -b value.

Ben and his friends are having a TV marathon, and after 4 hours they have watched 5 episodes of the show. About how long will it take to complete the season, which has 24 episodes?(Give good explanation and steps)
(redo)
Answer:
19.2 hours.
Step-by-step explanation:
There are 60 minutes in an hour.
60 x 4 = 240
There are 240 minutes in 4 hours.
Next, find out how long each episode is.
240 / 5 = 48.
48 minutes is how long each episode is.
48 x 24 = 1152
The entire season would be 1152 minutes.
1152 / 60 = 19.2.

Convert 253 into a hexidecimal
Answer:
0xFD
Step-by-step explanation:
To convert 253 into hexadecimal, divide the number by 16 repeatedly and record the remainders.
Explanation:To convert 253 into hexadecimal, you need to divide the number by 16 repeatedly and record the remainders. The most significant digit of the hexadecimal representation will be the last remainder obtained. So, let's proceed:
253 divided by 16 is 15 with a remainder of 13 (D in hexadecimal).15 divided by 16 is 0 with a remainder of 15 (F in hexadecimal).Therefore, 253 in hexadecimal is DF.

The number of dogs in a city is declining at a rate of about .08% each
year. If there were 3500 cats to begin with, how many will there be in 10
years?
Answer:
There will be 3472 cats in 10 years
Step-by-step explanation:
There were 3500 cats
The number of dogs in a city is declining at a rate of about 0.08% each year.
We are supposed to find the no. of cats in 10 years
Formula :[tex]N(t)=N_0(1-r)^t[/tex]
Where N(t) = Remaining cats after t days
[tex]N_0[/tex] = Initial population
r = rate of depreciation
t=time
So, No. of cats remained after 10 years = [tex]3500(1-\frac{0.08}{100})^{10}=3472.100[/tex]
Hence There will be 3472 cats in 10 years

0=7x-14
Add 14 to both sides:
7x=14
Divide both sides by 7:
x=2
