Answer:
students preferred alternative music
= 461/1940 ×100%=23.7%
See tha attached pdf file and let me know how useful this answer is.
Either the amount of galleons or the galleys.
if given the amount of galleons, you can find the amount of galleys by dividing the number of given galleons by 5.
if given the amount of galleys, you can find the amount of galleons by multiplying the number of given galleys by 5.
Answer: it moves at a constant speed and stays in the same direction
Step-by-step explanation:
It does this because there is no friction or nothing pushing on it therefore there is nothing to slow it down or speed it up

Answer:</h3>
42. 29°
43. 3x³ +2x² -3x +10
44. 20a² +68a
<h3>
Step-by-step explanation:</h3>
42. The right-angle corner tells you the two marked angles are complementary — they sum to 90°.
(-3x +20)° + (-2x +55)° = 90°
-5x +75 = 90 . . . . . . . . . . collect terms, divide by °
-5x = 15 . . . . . . . . . . . . . . . subtract 75
x = -3 . . . . . divide by the coefficient of x
The angle of interest is (-3x+20)°. Filling in the found value for x, we have ...
(-3·(-3) +20)° = 29° = m∠BDC
___
43. The distributive property is useful for multiplying polynomials.
(x +2)(3x² -4x +5) = x(3x² -4x +5) +2(3x² -4x +5)
= 3x³ -4x² +5x +6x² -8x +10 . . . . . eliminate parentheses
= 3x³ +2x² -3x +10
___
44. Area is the product of length and width, so this becomes a problem in multiplying polynomials.
area = (5a +17)(4a) = 20a² +68a . . . . area in square feet
