Answer:
48 minutes
Step-by-step explanation:
25=3 400/25=16x3=48
Answer:
48 minutes
Step-by-step explanation:
25 words - 3 minutes
400 words - x minutes
Cross multiply
25x = 400 x 3
25x = 1200
Divide both sides by 25
x = 1200/25
x = 48

Emma's Pizza can make 12 pizzas in 40 minutes. How many pizzas can they make in 5 hours?
Answer:
90
Step-by-step explanation:
Change 5 hours to minutes. (5x60, and 300 minutes)
Divide 300 by 40. (7.5)
Then, multiply 7.5 by 12 (90)
Answer:
90 pizzas
Step-by-step explanation:
We know 5 hours = [tex]5\times60 = 300[/tex] minutes
If you consider 20 minutes as a period, 5 hours .as well as 300 minutes. contains [tex]\frac{300}{20} = 15[/tex] periods.
Emma can make 12 pizzas in 40 minutes.
So she can make 6 pizzas in 20 minutes (in half time)
In 1 period she makes 6 pizzas.
In 15 periods she makes [tex]15\times6 = 90[/tex] pizzas (Answer.)

Answer: 1.35
Step-by-step explanation:
Answer:
1.35
Step-by-step explanation:
We need to identify our independent variables and dependent variables.
The number of papers graded depend on the amount of time.
The amount of time is the independent variable
The papers graded depends us the dependent variable
Divide the independent variable by the dependent variable to find papers per minute
For Ms.Mitchell the papers per minute is
For Mr.Rector, the papers per minute is
Subtract 2.4 from 3.75.
The answer is 1.35

Farah harvests 20 pounds of tomatoes from her garden. She needs 4 4/5 pounds to make a batch of soup. Additionally, if she uses 5.6 pounds of tomatoes to make spaghetti sauce, how many batches of soup can Farah make?
Answer:
1 batch
Step-by-step explanation:
Farah needs 4 and 4/5 pounds of tomatoes & and additional 5 and 3/5 pounds of tomatoes to make soup.
4.8 + 5.6 = 10.5 pounds per soup
10.5*2 = 21 > 20 pounds
Farah would need one more pound of tomatoes in order to make 2 batches of soup. Therefore she can only make 1 batch.

The function table below represents the linear function y = 4x – 3. Which answer represents the outputs of the function table
Answer:
Here we can not see the options, so i will answer in a general way.
When we have a function y = f(x), we define:
x as the input
y as the output.
so f(x) is some kind of "machine", in wich we put an input x, and the "machine" does something and returns an output y.
In, this case, we have:
y = f(x) = 4*x - 3
then if we give this function different inputs, we will get different ouputs.
for example, if we use the input x = 0, then the output is:
y = f(0) = 4*0 - 3 = -3
Then if we made a table for inputs and outputs, we will have the data:
[tex]\left[\begin{array}{ccc}inp&out\\x&y\\0&-3\end{array}\right][/tex]
We can rewrite this table in a general way as:
[tex]\left[\begin{array}{ccc}inp&out\\x&4*x - 3\end{array}\right][/tex]
This means that for every input x, the output is always 4*x - 3.
To complete this type of tables, we usually use different values of x, for example here I will use some different ones:
y = f(3) = 4*3 - 3 = 12 - 3 = 9
y = f(10) = 4*10 - 3 = 40 - 3 = 37
y = f(-1) = 4*-1 - 3 = -4 - 3 = -7
Then we will have a table like:
[tex]\left[\begin{array}{ccc}inp&out\\3&9\\10&37\\-1&-7\end{array}\right][/tex]
Concluding, the thing that will always represent the output of our function is: 4*x - 3.
Erika decided to compare her observations to the average annual trend, which shows the water rising 1.8 mm/year. Remember, she used 6.2 years as her time period. Explain how she would calculate the difference between how much the water level fell in the part of the river she observed.
Answer:
Change in water level over thr period Given is 11.16 mm
Step-by-step explanation:
The change in water level. In the part of the river observed will be ;
Water level. = The rate of change in water level per year * period
Rate of change in water level = 1.8mm /year
Number of years = 6.2
The change in water level is thus :
1.8 mm / year * 6.2 years
= (1.8 mm / year * 6.2
= 11.16 mm

This is the answer if its expanded. The question was sort of scarce so if this is wrong im sorry.
The expansion of the given logarithm [tex]\mathbf{Log_3 (4x^2)}[/tex] is [tex]\mathbf{= 2log_3(2)+2log_3(x)}[/tex]
What is the expansion of the logarithm?A Logarithm is an exponent to which a base must be raised in order to result in a given number. The expansion of the logarithm takes a predictable approach and set guidelines.
Using the set formula for solving logarithms;
[tex]\mathbf{log_a(x^n) = n \ log_a \ x}[/tex]
Let's assume that the correct equation given is:
[tex]\mathbf{=Log_3 (4x^2)}[/tex]
Using the above formula, we have
[tex]\mathbf{= 2 Log_3 (4x)}[/tex]
By expansion;
[tex]\mathbf{= 2log_3(2)+2log_3(x)}[/tex]

Which statement describes the end behavior of the function f(x) = 8|x − 1| + 13?
A.
As x approaches negative infinity, f(x) approaches negative infinity.
B.
As x approaches negative infinity, f(x) approaches positive infinity.
C.
As x approaches positive infinity, f(x) approaches negative infinity.
D.
As x approaches positive infinity, f(x) is no longer continuous.
The statement that describes the end behavior of the function f(x) = 8|x − 1| + 13 is:
As x approaches positive infinity, f(x) approaches negative infinity.C.
Let's analyze the function.
The function f(x) = 8|x − 1| + 13 involves the absolute value of x − 1, which means that the expression inside the absolute value will always be non-negative.
x approaches positive infinity, the value of x − 1 also approaches positive infinity.
Since the absolute value of a positive number is equal to the number itself, we can simplify the expression to f(x) = 8(x − 1) + 13.
As x approaches positive infinity, the term 8(x − 1) becomes larger and larger, making f(x) approach negative infinity.
The constant term 13 does not have a significant impact on the end behavior as x becomes increasingly large.

What is the common ratio for geometric sequence: 5,15,45,135 ?
Answer:
the common ratio is 3
Step-by-step explanation:
to solve for the common ratio, I like to take the second term and divide it by the first term
15/5 = 3
then I will check the rest of the terms
15*3 = 45
45*3 = 135
It looks like the common ratio is correct!
