Answer:
Question 1:
So you have 80 gummies and take 2 a day for 40 days
2(40) = 80
So at the end of 80p days, 0 gummies will be left
Question 2:
Now you have 90 and take 3 a day for 40 days
3(40) = 120
You will not have enough to cover the entire 40 days if you take 3 a day.
Hope this helps :)
Answer:
See below ~
Step-by-step explanation:
Question #1
80 vitamin gummiesUsage rate = 2 per day for 40 daysRemaining = 80 - 2(40) = 80 - 80 = 0Question #2
90 jelly bean vitaminsUsage rate = 3 per day for 40 daysRemaining = 90 - 3(40) = 90 - 120 = -30But negative is not a possible answer ⇒ lowest possible is 0If the function f(x) = 5(2x) is squared, which function is produced?
The function is a linear function, and the equation of the function when squared is (f(x))² =25(4x²)
How to determine the new function?The equation of the function is given as:
f(x) = 5(2x)
When the function is squared, we have:
(f(x))² =(5(2x))²
Evaluate the exponent
(f(x))² =25(4x²)
Hence, the equation of the function when squared is (f(x))² =25(4x²)

Newton's Law of Cooling is used in homicide investigations to determine the time of death. The normal body temperature is 98.6°F. Immediately following death, the body begins to cool. It has been determined experimentally that the constant in Newton's Law of Cooling is approximately k = 0.1947, assuming time is measured in hours. Suppose that the temperature of the surroundings is 60°F.

I think AC is 6.
Step-by-step explanation:
This looks like an equilateral triangle so that means because there is a 3 on one side of the line it should be the same on the other side of the line so 3 x 2 = 6.
Step-by-step explanation:
[tex]triangle \: abd \\ using \: pythagoras \: theorem \\ {hyp}^{2} = {adj}^{2} + {opp}^{2} \\ {12}^{2} = {3}^{2} + {opp}^{2} \\ 144 = 9 + {x}^{2} \\ 144 - 9 = {x}^{2} \\ 135 = {x}^{2} \\ take \: the \: square \: of \: both \: sides \\x = 11.62[/tex]

It takes staff members 162 minutes total each night to clean all six ovens. If each staff
member works for 18 minutes, how many staff members does it take to clean the
ovens?
Answer:
9
Step-by-step explanation:
If it takes 162 minutes each night to clean all 6 ovens, and each staff member works for 18 minutes each then we have to use division to find out how many staff members it will take to clean the ovens.
First we have to divide 162 by 18 which equals 9. This is a one step problem, so 9 is the answer.
It will take 9 staff members to clean all 6 ovens.
Happy Holidays
It takes 9 staff members to clean all six ovens, with each staff member working for 18 minutes.
Given that total cleaning time is 162 minutes
Time per staff member is 18 minutes
To find the number of staff members (N), we divide the total cleaning time by the time per staff member:
N = Total cleaning time / Time per staff member
N = 162 minutes / 18 minutes
N = 9
Therefore, it takes 9 staff members to clean all six ovens, with each staff member working for 18 minutes.

Answer:
First, the student performed what was inside of the parentheses and was exponential, which is correct. We know this because of the rules called order of operations, outlined by PEMDAS, which tells us to perform mathematical operations in the following order: parentheses, exponents, multiplication, division, addition, subtraction.
So by the rules I just outlined, next the student should have performed the multiplication, but instead performed subtraction, which is incorrect.
The following is the correct simplification of the expression:
23 - 8 times 2 + 3 by the power of 2
So first we should perform parentheses, but there are none. So we move to the next option in the list, which is exponents, which we do have (3^2).
23 - 8 * 2 + 3^2
23 - 8 * 2 + 9
Next in PEMDAS comes multiplication and division. This means the next step in simplifying the expression is to evaluate 8*2.
23 - 16 + 9
Next in PEMDAS is addition, so we should perform the operation -16 + 9.
23 - 7
Finally, the last step in PEMDAS is to simplify the remaining operation (subtraction).
16
Therefore, the student did the first step correctly but performed the second step incorrectly. The final answer should be 16 after simplification.

Answer:
This method is incorrect.
Step-by-step explanation:
The student's understanding of an exponent -1 is correct, but applying it to the inverse function f^-1(x), is wrong.
The method to find inverse function is to replace f(x) with y, switch x and y, then solve for y.
To use the (incorrect) "simple method" Put a 1 on top and move the function to the bottom (denominator).
For example, let's look at the function f(x) = x+3
Write y in place of f(x).
y = x + 3
Switch x and y.
x = y + 3
Solve for y.
Subtract 3.
x - 3 = y
Rewrite.
y = x - 3
This is the proper inverse function.
f^-1 (x) = x - 3
Using the (incorrect) "simple method"
f(x) = x + 3
f^-1(x) = 1/(x+3)
This shows that the shortcut doesnot work, its wrong. To do it correctly, switch x and y and solve for y.

How many games did the team play altogether?
Using proportions, it is found that:
a) The table is completed with 0.1.b) The team played 75 games.What is a proportion?A proportion is a fraction of a total amount.
Item a:
The sum of the frequencies is of 1, hence, the table is completed with 1 - (0.55 + 0.35) = 0.1.
Item b:
Considering that there were n games, we have that:
The team won 0.55n games.The team lost 0.35n games.The difference was of 15, hence:
0.55n - 0.35n = 15
0.2n = 15
n = 15/0.2
n = 75
The team played 75 games.

Amy and Julie are going camping.
Each of them both has a bag of marshmallows. The bag of marshmallows has 30 marshmallows inside. The girls also bring crackers. If Amy and Julie make 15 s'mores, how many crackers and marshmallows did they use?
Answer:
60 marshmallows and 30 crackers
Step-by-step explanation:
Each girl brought a bag of marshmallows containing 30 marshmallows inside. 2 x 30 = 60 marshmallows altogether.
Since there are 15 s'mores, we have to distribute the marshmallows equally.
60 ÷ 15 = 4 marshmallows in each. But if we multiply that again ( 15 x 4 ) we get 60 again. Thus, they used 60 marshmallows altogether.
The girls make 15 smores. A s'more has two crackers inside one.
2 x 15 = 30 crackers.
Hope this helped.
Answer:
60 marshmallows and 30 crackers
explanation:
1. 15 x 4 = 60
60 divided by 15 = 4

28.26 x 9/3
28.26 x 3
answer = 84.78
Answer:
84.78 inches cubed
Step-by-step explanation:
You need to comprehend the volume formula for cones
Volume Formula for Cones: V=1/3hπr²
Your measurements:
9 inches for height
3 inches for radius
**Radius is half of a circle and diameter is full of the circle/base.***
Equation:V=1/3 x 9in x π x 3²
You should do 3 squared first so that you can input it into your calculator easily.
V=1/3 x 9in x π x 9
Now on a calculator do 1 divided by 3 which is the "1/3" in the formula.
Then multiply 9, 3.14 for pi, and 9 for radius.
Note: You should do 3.14 for pi not the whole pi symbol on the calculator.
Your answer: 84.78 in cubed
