Answer:
30 violin players
Step-by-step explanation:
To answer this question, all you have to do is multiply:
10 cellists * 3 violin players for every cellist = 30 violin players in total
Hope this helps :)
Answer:
2nd degree.
Step-by-step explanation:
The degree is the highest exponent of a polynomial. Therefore, since the only term with an exponent is 4x²y, the degree is 2.
Answer:
The selling price is $28.75b.
Step-by-step explanation:
There are no options given but I will represent the word problem mathematically.
Let b stand for all the birdbath. If the owner pays $25 for each, then he pays $25b.
Selling them for 15% more means, 15% of the cost price was added to the original price. Finding 15% of cost price we have:
15% x $25b = 0.15 x $25b = $3.75b.
Therefore, the selling price is given as
$25b + $3.75b = $28.75b.
Answer:
1.44
Step-by-step explanation:
No. of warp coils manufactured in one group = 36
defect rate = 4%
That is 4 out of every 100 warp coil is defective
No. of defective warp coil in one group = 4% of warp coil in one group
= 4% of 36 =4/100 *36
= 1.44
Thus, there are 1.44 defective coil in each group.
Since, mean number is average number of defect.
So if each group has 1.44 defective coils then mean for all the group will remain same i.e 1.44
Answer:
x = -5/6, +4/3
Step-by-step explanation:
You want to look for two factors of 18·(-20) = -360 that have a sum of -9. They are -24 and +15. These let you rewrite the middle term as two terms:
y = 18x^2 -24x +15x -20
Now, you can factor by grouping the terms 2 at a time.
y = 6x(3x -4) +5(3x -4)
y = (6x +5)(3x -4)
These factors are zero when y = 0, so the zeros are ...
x = -5/6 and x = 4/3

Sometimes when I'm really stumped with roots of polynomials, I use a graphing calculator to find them.
_____
Factors of -360 are ...
-360 = -360·1 = -180·2 = -120·3 = -90·4 = -72·5 = -60·6 = -45·8 = -40·9 = -36·10 = -30·12 = -24·15 = -20·18
