Answer:
Medium: 4 and Large: 6
Step-by-step explanation:
Factor pairs that are equivalent to 10:
1,9
2,8
3,7
4,6
5,5
and so on. So you could do 2.4*9 and 1.8*1. If that doesn't work, switch it around. This coud probably take 1/2 of a hour or more. But it'll be worth it if it's a grade. :3
In the end, I'm pretty sure you should be able to get the answer:
Medium cups: 4
Large cups: 6
1.8 multiplied by 4 would get you 7.2 and 2.4 multiplied by 6 would get you 14.4. If you add them all up, you would get a 21.6! If you didn't, check your math again.
Answer:
<u>There are:</u>
- 6 red balls - R
- 5 black balls - B
- Total number = 11 balls
<h3>A. Without replacement</h3>
i. <u>Two blacks </u>
ii. <u>The first is black</u>
or, alternatively
- P(BR or BB) = 5/11*6/10 + 2/11 = 3/11 + 2/11 = 5/11
iii. <u>Both are of same colour</u>
- P(BB or RR) = 2/11 + 6/11*5/10 = 2/11 + 3/11 = 5/11
<h3>B. With replacement</h3>
i. <u>Two blacks </u>
- P(BB) = 5/11*5/11 = 25/121
ii. <u>The first is black</u>
or alternatively
- P(BR or BB) = 5/11*6/11 + 25/121 = 30/121 + 25/121 = 55/121 = 5/11
iii. <u>Both are of same colour</u>
- P(BB or RR) = 5/11*5/11 + 6/11*6/11 = 25/121 + 36/121 = 61/121
If the book stores sells 5 books for 27.25, then 1 book costs
27.25/5=5.45
the online store sells one book with the price of
32.16/6=5.36
the online store has a lower unit price
For this case we have the following inequality:
To find the solution we follow the steps below:
We apply distributive property on the right side of inequality:
Adding 13 to both sides of the inequality we have:
We subtract 6x on both sides of the inequality:
Thus, we have that any value of "x" makes the inequality fulfilled. Thus, the solution is given by all real numbers.
Answer:
The solution set is (-∞,∞)
