Answer:
2898
Step-by-step explanation:
number of people * number of pages in each book they read =total
mystery bookclub:
5 * 1,296 = 6480
fantasy bookclub:
9 * 398 = 3582
mystery - fantasy = difference in books between the two groups
6480 - 3582 = 2898
possible equation:
(1296 x 5) - (398 x 9) = x
x = answer

Step-by-step explanation:
anonymous is another word for unknown, i learned this in gamer talk ;P
Answer: Unknown.
Step-by-step explanation: When any author is anonymous whether they write myths, legends, short stories, etc, it means that their name is hidden or unknown. If you looked it up online, it would tell you this, "(of a person) not identified by name; of unknown name." Therefore, anonymous means an author not identified who is unknown.

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.
a) Find a function T(t) that models the temperature t hours after death.
b) If the temperature of the body is now 72°F, how long ago was the time of death?

If 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)

3 x 3 x 3.14 = 28.26
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

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
2. 15 x 2 = 30
231 - 7a = 98
How to solve this
Answer:
19
Step-by-step explanation:
231 - 7a = 98 = -7a + 231 = 98
Subtract 231 from both sides to get -7a = -133
Divide by -7 on both sides to get a = 19
Answer:
a = 19 is the correct solution.
Step-by-step explanation:
Step 1 : Start by simplifying both sides of the problem.
231 − 7a = 98
231 + − 7a = 98
−7a + 231 = 98
Step 2 : Next step is to subtract 231 from both sides
−7a + 231 − 231 = 98 − 231
−7a = −133
Step 3: Finally, divide both sides by -7.
( When I use the symbol /, it signifies I'm dividing.)
-7a/-7 = -133/-7
-133 divided by -7 equals 19
This shows that a = 19. I hope this helps! :D
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.

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]
using the opposite side of triangle and

Answer:
the sports players drank 13 cups
Step-by-step explanation:
1 cup equals 0.25 quarts which means 1 quart would equal 4 cups. This means there were 16 cups in total during the game. If there were only 3 cups left afterwards, that means 13 of the 16 cups were taken.

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.
