Answer:
27 girls and 15 boys
Step-by-step explanation:
To solve this, I just used guess and check.
9:5 is a ratio, which means we can multiply each side by any number as long as we do it to both sides.
If we multiply the ratio by 3, we get (9 x 3) : (5 x 3) which is 27:15
And as it turns out, 27-15 is 12, which in this context means there are 12 more girls in drama club, so it works out.
I think it might be experimental probability:)
Logan, the way you have phrased this question makes it a bit hard to follow. I'm going to take the liberty of paraphasing it:
"Catalan drives an average of 1.4 times faster during the first 105 miles of her trip than she does during the second 105 miles."
As we are told, let X represent her speed during the first 105 miles of her trip. She drives more slowly during the second 105 miles. Thus, her speed during the 2nd 105 miles is X/1.4.
Remember: distance = (rate)(time), or time = (distance)(rate)
We need to determine an expression for the time she spends driving. Let T1 be the time required to drive 105 miles at speed X mph and T2 be the time required to drive 105 miles at speed (X/1.4) mph.
What is the total time required to drive these 210 miles?
Total time = (time required to drive 105 miles at X mph) + (time required to drive 105 miles at X/1.4 mph).
This gives you TIME SPENT DRIVING as a function of X, her speed during the first 105 miles of driving.
Answer:
Step-by-step explanation:
Zero in on the highest power of x. It's 4. Thus, this polynomial is of the 4th degree.
Note: Please use " ^ " to indicate exponentiation:
-2x^4 - x^3 + 8x^2 - 12
Answer: 68x + 36y
Step-by-step explanation:
Combine Like Terms:
= 19x + 4y + 49x + 32y
= (19x + 49x) + (4y + 32y)
= 68x + 36y
Hope this helped you!
