Renee is playing a game with marbles and a spinner. The spinner has four sections: orange, black, purple, and white. The marbles
2 answers:
Answer:
Is the chance of the colours matching.
Step-by-step explanation:
The possibility of the spinner landing on an orange side is
and the possibility of the marble being orange is in this case you have to remember, in the fraction, you have 4 possibilities and 1 desirable outcome, when you have two dependant possibilities you have to multiply them:
And the result of that multipliction is which is the probability of the marble and the spiner colours matching.

7. For this one, we need an equation. Lets make x = the price of the computer. Since the price of the printer is 30% the price of the computer, we can make that .3x, because a number multiplied by .3 will give you 30% of your original number. So, our equation will be:
Since x is the cost of the computer, you have your answer right there. The computer costs $2,028.
8. For this one we're going to need a proportion, but first we need to find out how much of the percentage of seeds Cliff planted.
% of seeds planted per person:
Ali - 40
Ben - 45
Cliff - x
All percentages add up to 100, so we'll make an equation to figure this out:
Therefore, Cliff planted 15% of the seeds. Since Cliff planted 15% of the seeds, and he planted 87 total, 15% of our total number of seeds planted is 87. We can now make a proportion to figure out how many seedlings were planted all together.
We can now cross multiply in order to get a solvable equation:
The total number of seedlings planted was 580.
Sorry if this is confusing at all, hope I helped!
