What is multiplication?In maths, to multiply means to add equal groups. When we multiply, the number of things in the group increases. The two factors and the product are parts of a multiplication problem.
Given that, Mitosis is a process of cell reproduction in which one cell divides into two identical cells. E. coli is a fast-growing bacterium that is often responsible for food poisoning in uncooked meat. It can reproduce itself in 15 minutes.
In the beginning, there are 100
After 15 minutes, there are 2*100=200
After 30 minutes, there will be 2*200 =400
After 45 minutes = 400*2 = 800
After 60 minutes = 800*2 = 1600
Hence, in 1 hour there will be 1600 E. coli bacteria.

If the dimensions of a parallelogram are increased by a factor of two, how will the perimeter of the object be affected?
increase by a factor of four
decrease by a factor of one-fourth
increase by a factor of two
decrease by a factor of one-half
Answer:
increase by a factor of two
Step-by-step explanation:
Given that dimension of a parallelogram are increased by a factor of 2.
Let the sides of the parallelogram be l and w.
Then perimeter = 2(l+w)
When each side is increased by a scale factor of 2, we get new dimensions as
2l and 2w
Hence new perimeter = 2(2l+2w) = 4(l+w)
= twice as old perimeter
Hence increase by a factor of two

What is 3 1/3 +(-2 1/4) + 1 5/6 as a mixed fraction
By separating between whole numbers and fractions, we will see that the sum is equal to 2 + 11/12.
How to add mixed numbers?
Here we want to perform the sum:
(3 + 1/3) + (-2 - 1/4) + (1 + 5/6)
We separate between whole and fractions, so we get:
(3 - 2 + 1) + (1/3 - 1/4 + 5/6)
The left part is easy: 3 - 2 + 1 = 2
The right part needs to find a common denominator, we will use 12.
1/3 - 1/4 + 5/6 = 4/12 - 3/12 + 10/12 = 11/12
Then the sum is:

The scatter plot below shows the number of pizzas sold during weeks when different numbers of coupons were issued. The equation represents the linear model for this data. y = 3.4x + 43
According to the model, what is the average number of pizzas sold in one night if no coupons are issued?
Question 5 options:
A 43
B 0
C 11
D 21
Answer:
option: A is correct.
Step-by-step explanation:
We are asked to find the average number of pizzas sold in one night if no coupons are issued.
i.e. we have to find the value of y such that x=0 i.e. no coupon was issued.
We are given a equation which represents the linear model for this data:
y = 3.4x + 43
where y denotes the average number of pizza sold and x denotes the number of coupons issued.
Hence when x=0 we have value of y from the above linear equation as:
y=3.4×0+43=0+43=43
i.e. y=43.
Hence, average number of pizzas sold in one night if no coupons are issued are 43.

Pythagorean Theorem in Cones. I need a lot of help.
Two letter are chosen without replacement at random from the English alphabet. If y is considered to be a consonant, find the probability that both are vowels and that both are consonants
Final answer:
Explanation of the probabilities of choosing two vowels and two consonants from the English alphabet without replacement.
Explanation:
The probability of choosing two vowels:
There are 5 vowels in the English alphabet: a, e, i, o, u.
The total number of ways to choose 2 letters out of 26 is C(26, 2) = 325.
The number of ways to choose 2 vowels out of 5 is C(5, 2) = 10.
Therefore, the probability of choosing 2 vowels is 10/325 = 2/65.
The probability of choosing two consonants:
The total number of ways to choose 2 consonants out of the remaining 21 letters is C(21, 2) = 210.
Therefore, the probability of choosing 2 consonants is 210/325 = 42/65.

A drama club is planning a bus trip to New York City to see a Broadway play. The table represents the cost per person for the bus rental compared to the number of people going on the trip. What function models the data, and how much per person will it cost if 12 students go on the trip?
TABLE BELOW
Number of Students (n) 3 6 9 16
Cost per Student (c) $24 $12 $8 $4.5
A) nc= 9, $10
B) nc= 72, $6
C) n/c= 72, $12
D)n/c= 9, $12
As we can see from the table there is a pattern to the whole data in the table. A closer look reveals that when we multiply the number of students, n by the cost per student, c we get a constant number, 72. Let us see what we mean here:
[tex]3\times24=72[/tex][tex]6\times 12=72[/tex][tex]9\times 8=72[/tex][tex]16\times 4.5=72[/tex]Thus, the function which models the data is the [tex]nc=12[/tex].
Now, let us move on to the next part of the question:
If 12 students go on the trip then the cost per student as per this model will be:
[tex]\frac{72}{12}=6[/tex] dollars=$6
Therefore, out of the given options, the option the correct option is number B.

The probability of selecting an oatmeal cookie from a bag of 30 cookies (6 vanilla, 12 chocolate, and 12 oatmeal) is 2/5, which is answer choice D.
The student's question involves calculating the probability of selecting an oatmeal cookie from a bag containing multiple types of cookies. The total number of cookies is 30, comprising 6 vanilla, 12 chocolate, and 12 oatmeal cookies. To find the probability of selecting an oatmeal cookie, we use the formula:
Probability (selecting an oatmeal cookie) = Number of oatmeal cookies / Total number of cookies.
This gives us:
Probability (selecting an oatmeal cookie) = 12 / 30 = 2 / 5
So, the probability that an oatmeal cookie is randomly selected is 2/5, which corresponds to answer choice D.

What does X represent in this story;
• Diego has 24 ounces of juice. He pours equal amounts for each of his three friends, and then add six more ounces for each.
The equation is
3(x + 6)= 24
X= 2
I need to know what X represents.
Here the total amount of the juice is 24 ounces. Diego poured equal amounts to his three friends. But that equal amount is unknown. Then he add 6 to each that is represented by x +6. Hence, the x is the initial amount poured to each three friends.
What is polynomial expression ?A polynomial expression is composed of some coefficients and indeterminants that involves basic basic arithmetic operations. Where the indeterminants or unknowns are basically represented by the letters x or y.
Here, Diego has 24 ounces of juice. He pours equal amounts of juice to his three friends. The mount he poured to each friends is unknown here. Hence, let it be x.
Then, he added 6 more ounces to each these x quantity that is represented by x + 6. Now, 3 friends have this x + 6 ounces of juice then total equals 24.
i.e, 3 (x + 6) = 24
3x +18 = 6
3x = 24- 18 = 6
x = 6/3 = 2.
Hence, here, x represents that Diego poured initially to each friends before adding 6 more ounce.

Final answer:
In the story problem, x represents the initial amount of juice in ounces (2 ounces) that Diego pours for each of his three friends before adding an additional six ounces to each.
Explanation:
In the given story problem, x represents the initial amount of juice in ounces that Diego pours for each of his three friends before adding six more ounces to each. To understand what x represents, let's explore the equation 3(x + 6) = 24. This equation tells us that Diego has 24 ounces of juice in total, which is then divided equally among his three friends and after the division, he adds six more ounces to each friend's portion.
Now, if we follow the equation 3(x + 6) = 24 and solve for x, we find that:
Multiply each side of the equation by 1/3 to isolate the term with x, yielding x + 6 = 8.Then, subtract 6 from each side to solve for x, resulting in x = 2.This means that Diego initially pours 2 ounces for each friend and then adds 6 ounces to each, totaling 8 ounces for each friend.
