Answer:
1. Anne = 21 Bobby=35, 450, 70+40+30=140
Step-by-step explanation:
- 1 21÷3=7
- 7×5=35
- 7-2=250
- 5=250
- 1=50
- 2×50+7×50=100+350=450
- 450
- we can see that it's multiplied by 10, so 70+40+30=140
Answer: One of them is the set {1,2,3,4,5,6}itself; one is the empty set, containing no elements. “Proper subset of a set ” usually denotes a subset in which at least one element of the original set is missing; so one of the subsets - the original set iitself - is not a proper subset. Therefore the answer is 63.
Step-by-step explanation:
Hi!
When we write a number in scientific notation, we write it like this:
N × 
N = a number between one and 10
x = negative if the decimal is moved to the right. positive if moved to the left.
Okay, so
we need to move the decimal in the number <span>0.0059
to the right to make it
between one and 10.
0.0059
00.059
000.59
0005.9
5.9N = 5.95.9 </span>×

Since we moved the decimal to the right 3 times,
x = -35.9 × 
^ the answer
Hope this helps! :)
There are 14 possibilities for first place.
There are 13 possibilities for second place, since a dog can't get both first and second place.
There are 12 possibilities for third place, since a dog can't get both first, second, and third place.
There are 11 possibilities for fourth place, since a dog can't get both first, second, third, and fourth place.
Multiply them together and get 24024 possibilities.
Hope this helps!
