8 out of 21 instruments in the band are woodwind. if there are 63 instruments in the band, how many more are not woodwinds than woodwinds?

Answers

Answer 1

Answer:

15 more are not woodwinds than woodwinds

Step-by-step explanation:

If there are 8woodwinds out of 21instruments, to know the number of woodwinds when we have 63instruments can be gotten as shown below;

8woodwinds = 21instruments

x woodwinds = 63instruments

Cross multiplying we will have;

x woodwinds × 21instruments = 8 woodwinds × 63instruments

x woodwinds = 8woodwimds × 63instruments/ 21instruments

x = 8×63/21

x = 24

This shows that there will be 24 woodwinds if there are 63 instruments

If there are 24woodwinds, number of those not woodwinds will be;

63-24 = 39

Therefore we have 24woodwinds and 39 that are not woodwinds.

To know how many more instruments that are not woodwinds than woodwinds, we will take the difference between those not woodwinds and those of woodwinds to give;

39-24 = 15

This shows 15 more are not woodwinds than woodwinds

Answer 2

Answer: Well21-8= 1363-21=4242-21=2113*2=26 tThere is 26 non woodwind instruments

Quadrilateral ABCD is a parallelogram with diagonals that intersect at point E. If AD=4w-5,DE=4,BE=x/2, and BC-7w-17, solve for x.

Answers

Given:
Quadrilateral ABCD is a parallelogram with diagonals that intersect at point E.
AD = 4w - 5
DE = 4
BE = x/2
BC = 7w - 17

AD and BC are parallelogram, this means that they are equal in measure.

AD = BC
4w - 5 = 7w - 17
4w - 7w = -17 + 5
-3w = -12
w = -12/-3
w = 4

AD = BC
4(4) - 5 = 7(4) - 17
16 - 5 = 28 - 17
11 = 11

DE = BE
4 = x/2
4*2 = x
8 = x

The value of x is 8.

Answer: The value of x is 8.

Answers

You first have to multiply 2.4 by 20. That equals 48, so you have to do 48 times 2 again, because one bottle cap is half of the scale used.

Final answer: 96 bottle caps. 48cm
Hope this helps!

First multiply: 2.4 by 20=48. Then you have to do it again to because one bottle cap is half of the scale used.

1.Do examples that support a conjecture prove the conjecture to be true?

Answers

Answer:

A conjecture is an “educated guess” that is based on examples in a pattern. ... However, no number of examples can actually prove a conjecture. It is always possible that the next example would show that the conjecture is false. A counterexample is an example that disproves a conjecture.
