Answer= 4 hours.
The first pipe can fill one pool in nine hours. So in one hour, it can fill 1/9th of the pool. Same with the other pipe, it can fill 1/6th of the pool in other hour.
So 1/9 + 1/6 would represent the first hour of filling the pool. Since 1/9 + 1/6 = .277.. , 27% of the pool is filled. Repeat this until you get to 100% (full pool).
First hour, 1/6 + 1/9 = .27
Second hour, 2/6 + 2/9 = .5
Third hour, 3/6 + 3/9 = .83
Fourth hour, 4/6 + 4/9 = 1.11
So in 4 hours, the pool will be filled.
Answer:
That their milkshakes need more caramel or less ice cream.
Step-by-step explanation:
We can see that Ari's numbers for a perfect milkshake gives us a caramel to ice cream ratio of 333 / 555 = 0,6.
But the Freeze Zone uses a caramel to ice cream ratio of 666 / 888 which is equal to 0,75.
Their milkshakes have less caramel and more ice cream than Ari's perfect milkshake so Ari will think that Freeze Zone's milkshakes are not sweet enough.
I hope this answer helps.
Answer:
P(B|S) = 0.95
Step-by-step explanation:
Hello!
A certain company claims that its e-mail filter has 95% accuracy.
Be the events
S: The e-mail is Spam.
B: The filter blocks a message.
If the filter has 95% accuracy it means that it'll block 95% of the spam, another way to put it is that out of 100 spam messages the filter will block 95 of them.
Expressing it in terms of probability we can say that the probability of the filter blocking a message given that it is spam is 0.95, symbolically P(B/S)=0.95
I hope you have a SUPER day!
Explanation:
Tommy calculated the area of the base by squaring the <em>diameter</em>, not the radius. If he's going to use the diameter in the area formula, he needs to divide the result by 4.
A = πr² = πd²/4
Answer:
5 > x
Step-by-step explanation:
3x+2>5x-8 rewrite the inequality by exporting like terms to the same side
2+8 > 5x - 3x now add/subtract like terms
10 > 2x divide both sides by 2
5 > x
