16 scarfs because every 4 scarfs takes 5 feet of fabric
20x-10y=60 simplified would be y=2x-6
slope : 2
The answer is 9 fish.
The density (d) is the number of units(n) per volume (V):
d = n/V We know: d = 0.3 fish/ft³. V = 30 ft³ n = ? d = n/V n = d * V n = 0.3 fish/ft³ * 30 ft³ n = 9 fish
you can use long division to do this:-
a + 3 ) a^2 + 2a + 3
= a - 1 remainder 6 or you can write it as a - 1 + 6 / (a + 3)
Answer:
40°
Step-by-step explanation:
The reference angle is the positive difference between an angle and the nearest multiple of 180°.
Here, the nearest multiple of 180° is -360°. The difference of interest is ...
|-320° -(-360°)| = 40°
The reference angle is 40°.
