1. You got it right.
4π/9 x 180/π = 80°
2. To get a coterminal angle you start with your angle and then you add or subtract 360° (one cycle around the circle).
-123+360+360 = 597°
-123-360 = -483°
3. The angle is 215° from the point (1,0) on the unit circle. The angle 215° is between 180° and 270° so it is in quadrant 3.
Answer:
"A half of a class and a half of a student got A on a test" this confuse me for a bit.... but i hope i got the right answer
Step-by-step explanation:
call number of students in the class is a
A half of a class and a half of a student got A on a test ->1/2 a +0.5 ?
1/2 a + 0.5 + 1 = 2/3 a
-> 1/2 a +1.5 = 2/3 a
-> 1.5 = 1/6a
-> a = 9
Find slope
slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
given (
(5,19) and (9,23)
slope=(23-19)/(9-5)=4/4=1
slope=1
equation with point (x1,y1) and slope is m is
y-y1=m(x-x1)
given
(5,19)
y-19=1(x-5)
y-19=x-5
y=x+14
Answer:
You can make 10 tortillas with one and a half kilograms of ground meat
Step-by-step explanation:
one and a half kilograms to grams
1.5kg x 1000 = 1500g
150 grams prepared to make 1 hamburger
than, 150 x h = 1500
h = 1500 / 150
h = 10
Answer:
6 because 9 is bigger than 9
