3. Janice has room for 6 books on a shelf.
How many different ways can she arrange the books on the shelf?
Enter your answer in the box.
Answers
By counting the numbers of options for each selection, we will see that:
A) There are 10,000 different codes.B) There are 90 different combinations.C) There are 720 different combinations.How to get the numbers of combinations?A) The code has five digits, and the first digit is fixed (we know that it must be 7) so we only care for the other 4.
The second digit has 10 possible options.The third digit has 10 possible options.The fourth digit has 10 possible options.The fifth digit has 10 possible options.The total number of combinations is given by the product between the numbers of combinations:
C = 1*10*10*10*10 = 10,000 codes
So the correct option is the first one.
B) Again, we need to count the number of options for each possible element.
There are 5 drinks, 6 main dishes, and 3 desserts.
So for a meal of 1 drink, 1 main dish, and 1 dessert, the total number of different combinations is:
C = 5*6*3 = 90
There are 90 different possible meals.
C) How Janice can arrange the 6 books?
We need to count how many options we have for each place on the shelf.
In the first place, there are 6 options (one for each book).In the second place, there are 5 options (because we already placed one).On the third place, there are 4 options.And so on for the other 3 places.Then the number of combinations is:
C = 6*5*4*3*2*1 = 720
There are 720 ways of ordering the books.

Please hurry on an exam The formula for calculating simple interest is I = prt. Which is the equivalent equation solved for r?
StartFraction I Over p t EndFraction = r
StartFraction p t Over I EndFraction = r
I minus p t = r
I + p t = r
Answers
Answer:
r=I/pt
Step-by-step explanation:
I = PRT is the formula for interest, and we need to solve it for R. Since all three of P, R, and T are multiplied, we send things to the other side of the equals through dividing. I = PRT I / P = RT to divide both sides by P I / PT = R to divide both sides by T So I / PT = R (the first choice) is the equation solved for R.

Mia paddled her canoe from the shore of a lake to an island. She stopped on the island to eat lunch, and then paddled her canoe back to the shore. The graph below shows Mia’s distance, in kilometers, from the shore over time. Based on the graph, which of the following statements is true?
Answers
It took Mia 40 minutes to get to the island, 30 minutes eating lunch, and 30 minutes back.
The speed of Mia on the way back to the shore is greater than speed on the way to the island
What is Speed?Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude
Speed = Distance / Time
Given data ,
Let the speed on the way to the island be S₁
Let the speed on the way back to the shore be S₂
where the Speed = Distance / Time
So , S₁ = ( 3 - 0 ) / ( 40 - 0 )
S₁ = 3/40 km/minutes
S₁ = 0.075 km/minutes
And , S₂ = 0.1 km/minutes
Now , S₂ > S₁
Hence , the speed on the way back to the shore is greater

Answer:
A. (12, -6)
Step-by-step explanation:
When a coordinate gets rotated into the bottom right quadrant of a graph, the x and y coordinates switch places and the y-coordinate becomes negative.
Since the coordinate pair was (6, 12), you would switch the spots of the coordinates to get (12, 6).
After that, make the y-coordinate negative (if the y-coordinate was originally negative, make it positive instead) to get (12, -6).
Therefore, the answer is (12, -6).

The correct product of 0.60 and 0.40 is 0.24 and the model used to describe is bottom left.
Let us find the product of 0.60 and 0.40.
Multiply the two numbers without considering the decimal point.
0.60 × 0.40
= 0.24
Let us consider the boxes as 1.
Now we have to find the number of boxes which are shaded for 24.
