A) It says in fraction form. y=5/4x +15
b) it says it should be a decimal. If you extend the line, it will reach 15.5 hours.
c) I think your answer was correct
Answer:
-11
Step-by-step explanation:
Plug in 0 for x and 3/5 for y into the expression
-4(0) + 5(3/5) - 14
Multiply the numbers inside the parentheses
0 + 3 - 14
3 - 14 = -11, which is your answer
First we will convert those radian angles to degrees, since my mind works better with degrees. Let's work one at a time. First,

. If we start at the positive x-axis and measure out 315 we end up in the 4th quadrant with a reference angle of 45 with the positive x-axis. The side across from the reference angle is -1, the side adjacent to the angle is 1, and the hypotenuse is sqrt2. The cotangent of this angle, then is 1/-1 which is -1. As for the second one, converting radians to degrees gives us that

. Sweeping out that angle has us going around the origin more than once and ending up in the first quadrant with a reference angle of 30° with the positive x-axis. The side across from the angle is 1, the side adjacent to the angle is √3, and the hypotenuse is 2. Therefore, the secant of that angle is 2/√3.
Answer:
6 complete costumes
Step-by-step explanation:
he has 27/2 total fabric
1 costume requires 1 2/4 + 3/4 of fabric, which is 2 1/4
we divide 27/2 by 9/4
27/2 x 4/9 = 6
0/5 1/5 2/5 3/5 4/5 5/5 hope this helps
