Answer:
1.25,but your teacher is prolly looking for a fraction so 1 1/4
Step-by-step explanation:
DO NOT PUT 20 THAT PERSON S WRONG
It is asking you to slice off 40% of the bounce height in each subsequent bounce.
So you start with full height 1, that's n = 0 bounces. Then after n = 1 bounce the new height is .6. After the second bounce, n = 2, the height becomes .6 X .6 = .36. And after n = 3, we have .6 X .6 X .6 = .216
So by induction we see that h(n = 5) = .6^n = .6^5 = 0.07776 = .078 of its original height or H = .078*200 = 15.6 ft. after five bounces. ANS. 16.0 if rounded to the nearest tenth

Answer:
i think its 7 units but im not completely sure
Step-by-step explanation:
To solve:
Let us convert the mixed fraction into fraction first,
On simplification we get,
Hence, the answer is,
A. What fraction of the band are woodwinds?
First, find common denominators for the first two. Let's use 15.
6/15 is brass (5x3=15, and 2x3=6)
5/15 is percussion (3x5=15, and 1x5=5)
Now, we add the two and subtract them from the whole.
6/15 + 5/15 = 11/15
15/15 - 11/15 = 4/15
4/15 of the band is woodwinds.
B. One half of the woodwinds are clarinets. What fraction of the band is clarinets?
To find this, we take our 4/15 and divide it by two. Thankfully, the numerator is an even number, so it splits in half easily.
4/15 divided by 2 = 2/15
2/15 of the band is clarinets.
C. One eighth of the brass instruments are tubas. If there are 240 instruments in the band, how many are tubas?
First, find 1/8 of the number of brass instruments.
6/15 of the band is brass.
We need to make this an equivalent fraction that is divisible by 8.
Both 6 and 8 go into 24, so we'll multiply our fraction by 4, since 6x4=24
The new fraction is
24/60
Now, we divide that fraction by 8, to find 1/8 of the brass instruments.
24/8=3
3/60 of the band is tubas.
To find the number of tubas out of a 240 instrument band, we multiply the fraction of tubas by the whole band.
3/60 x 240 = 12
There are 12 tubas in the band.
