By understanding the rate at which each oven bakes the bread, we can calculate that it would take the small oven 12 hours to bake the bread for one day.
To solve this problem, we need to first understand the rate at which each oven bakes the bread. When both ovens are working together, it takes 3 hours to bake a day's worth of bread. This means their combined rate of work is 1/3 of the day's bread per hour. However, when only the large oven is used, it takes 4 hours to complete the same amount of work. Therefore, the large oven's rate of work is 1/4 of the day's bread per hour.
Our goal is to find the small oven's rate of work. To do this, we subtract the large oven's rate of work from the combined rate of work. This leaves us with 1/3 - 1/4 = 1/12 of the day's bread per hour. Therefore, it would take the small oven 12 hours to bake the bread for one day on its own.

Answer:
X= 24
Step-by-step explanation:
Y was multiplied by 3 to equal 30, so same rules are applied and you multiply 8 by 3
Answer:
28 or 24 im not sure which
5%
20%
25%
The probability that the first card will be red, and the second card will be blue is 5%
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
P(event) = favorable outcomes / possible outcomes
p(red) = 1 / 5
p(blue) = 1 / 4 (since, the card is not replaced)
We know that, the probability that the first card will be red, and the second card will be blue: p(red then blue) = p(red) × p(blue)
p(red then blue) = 1 / 5 × 1 / 4 = 1 / 20
= 5%
Hence, the probability that the first card will be red, and the second card will be blue is 5%

Hi there!
First, for any of the five cards being drawn, there is a 1/5 chance, or 20%. So, the probability of a red card being drawn is 1/5. Then, since the card is not replaced, it becomes a 1/4, or 25%, chance of any card being drawn (besides red). So, the probability of a blue card being drawn is 1/4. So in order to find what the question is asking, we'll need to multiply the two fractions together.
1/5 x 1/4 = 1/20
1/20 = 5%
Therefore, the correct answer is 5%, or the second option.
Hope this helps!! :)
