Having a spot of difficulty after re-watching the main video a few times. I followed his example but the answer I got was 2 (yay...). I would appreciate the help!

The number of flour cups would be 20

and butter cups would be 10.

The explanation to this question this is

There are total 30 cups of pie crust made.

Now, 2

2:1 is the ratio given.

For flour cups

=  [tex]\frac{2}{3}[/tex] × 30

= 2 × 10

= 20

For butter cups

= [tex]\frac{1}{3}[/tex] × 30

= 1 × 10

= 10

So in total 30 cups of pie crust , there are 20 cups of flour and 10 cups of butter.

Mathematicians use the term "ratio" to compare two or more numbers. It serves as a comparison tool to show how big or tiny an amount is in relation to another.

Two amounts are compared using division in a ratio. In this case, the dividend is referred to as the "antecedent" and the divisor as the "consequent." For instance, out of a group of 30, 17 prefer to walk and 13 prefer to cycle in the morning. We write this information as 17: 13 to express it as a ratio.

The 86.9167 lbs was the projected weight overstated.

Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.

Given:

The baggage weight projected was 2,182 1/4 lbs= 2182.25 lbs  

The actual weight of all bags totaled 2,095 1/3 lbs=2095.33 lbs

According to given question we have

We know that

The overstated weight = Projected weight - Actual weight

The overstated weight = 2182.25 lbs -2095.33 lbs

The overstated weight = 86.9167 lbs

Therefore, the 86.9167 lbs was the projected weight overstated.

Answer:

B. Yes, because 27.4% take one vitamin and 49.5% take more than one vitamin, which is a total of 76.9% taking vitamins.

Step-by-step explanation:

You must add the percentages of the subjects and took vitamins AND did NOT gain weight. The other answer only adds the percentages of those who took vitamins and gained weight. You're looking for the percentage of everyone who took vitamins, regardless of if they gained weight or not.

11.4% + 16% = 27.4% - Takes one vitamin per day
23.5% + 26% = 49.5% - Takes more than one vitamin per day

27.4% + 49.5% = 76.9%

Therefore the student is correct, since it is more than 50% of the participants.

Population growth is exponential, growing by some multiple over time that is dictated by a rate. To find the population exponential growth formula, take this initial premise, the population multiplied by a rate, and equate it to the change in population with respect to time.

Number of bacteria present after 4 days will be 20.05 .

Given,

Initial population = 18

Growth rate = 2.74%

Here,

The exponential growth is given by ,

N = [tex]N_{0} (1 + r )^t[/tex]

N = population after time t

No = Initial population

r = growth rate

t = time

Here,

No = 18
t = 4 days

r =2.74% = 0.0274

Substitute the values in the formula ,

N = 18 [tex](1 + 0.0274)^{4}[/tex]

Answer: 4-digit numbers can be chosen that are even and greater than 3000 is equal to 192.

Step-by-step explanation:

Given data,

4-digit numbers can be chosen that are even and greater than 3000.

For even numbers, each formed 4-digit number must end with 2, 4, or 6. And each such number greater than 3000 must begin with 3, 4, 5, 6, or 7.

Since five digits [1–5] are available, the number may have four or five digits.

All five-digit numbers are greater than 3000, and there are 5! = 120 permutations of the five digits.

Four-digit numbers greater than 3000 must have one of three digits (3 or 4 or 5) as its first digit. The next three digits must be selected from the four remaining digits available, so the number of permutations is: 4 * 3 * 2 = 24.

There are 3 * 24 = 72 numbers of the form 3xxx, 4xxx, 5xxx (all of which are greater than 3000).

The number of possible sequences of [1–5] greater than 3000 include 120 four-digit numbers and 72 five-digit numbers, so the total is 192.

Therefore,

4-digit numbers can be chosen that are even and greater than 3000 is equal to 192.

An equation for the transformation of y = x vertical compression by a factor of 1/11 is; y = (1/11)x

Vertical compressions in transformations occur when a function is multiplied by a rational scale factor. This means that base of the function's graph would remain unchanged when a graph is compressed vertically because it is only the output values that will be affected.

Now, we are given the equation as; y = x

When it undergoes a vertical compression by a factor of 1/11, we can say that the new equation will be; y = (1/11)x

Thus, we conclude that an equation for the transformation of y=x

vertical compression by a factor of 1/11 is; y = (1/11)x
