Answer:
8 red marbles.
Step-by-step explanation:
All together we have 40 marbles. The fraction of marbles that are red is 1/5 which means that we should divide the total number of marbles, which is 40 by the denominator ( Bottom number of fraction ) 5 so that we get the number of groups that have 1 red marble in them. In this case we have 8 groups.
40/5=8
You always divide by the denominator ( Bottom number of fraction ) first and then you multiply your answer by the numerator ( Top number of fraction ) .
If each group has 1 red marble in it and we have 8 groups, it means that we have 8 red marbles in the bag.
1 * 8 = 8 red marbles in the bag
If the numerator (number above the fraction line) was more than one, then this would mean that we have more than 1 marble in each group of marbles.
Example:
If we had 3/5 we would have 3 marbles in each group of marbles. This means that instead of doing 1 * 8 we would have to do 3 * 8 = 24. We would have 24 red marbles in the bag.
Easy and quick way if you do not need the explanation:
Another way we could do this is by simply multiplying the fraction ( 1/5 ) by the total number of marbles ( 40 ). This would still give us an answer of 8 red marbles in the bag. 40/5=8, 8*1=8
Control = group with no music / maybe no variable?
Manipulated/independent variable = Number of tomatoes being grown
Dependent/responding = Number of tomatoes produced by each plant
Conclusion = Use four parts... Was your hypothesis correct or not and why...Cite numbers/evidence from experiment.... Were the results reliable?.... any improvements to be made
Answer:
We cant see what you are talking about we cant see the equation
Step-by-step explanation:
1. 3.0
2. 1.0
3. 18.0
5. 6.0
6. 10.0
7. 9.0
Laws of exponents:
(a^x)^y=a^(xy)
a^0=1 (a≠0)
Therefore
(7^13)^3.7^0
=(7^(13*3)). 1
=7^39
