Answer:

csc (- 30)° = - 2

Step-by-step explanation:

Using the trigonometric relationship

csc x = $\frac{1}{sinx}$ and the exact value sin30° = $\frac{1}{2}$

sin(- 30)° = - sin30° = - $\frac{1}{2}$ , thus

csc (- 30)° = $\frac{1}{-\frac{1}{2} }$ = - 2

Please help!!!! Describe how you would graph the equation y= -20x + 150.

deff fn [24]

First, plot the y-intercept which is 150. So, plot the point (0,150).
Then, just input values of x into the equation.
Use the value of x you input and y value you got after solving into (x,y) and plot the point.

EastWind [94]

Answer:

The least number of dinners that manny can make without any supplies leftover is 6 dinners

Step-by-step explanation:

Dinner = 1 box of pasta + 1jar of sauce

pasta is sold in package of 6 boxes

sauce is sold in in packages of 3

jars

what is the least number of dinners that manny can make without any supplies leftover?

Find the lowest common multiple of 6 boxes and 3 jars

6 boxes = 6, 12, 18, 24, 30, 36, 42,48

3 jars = 3, 6, 9, 12, 15, 18, 21, 24, 27, 30

The lowest common multiple of 6 boxes and 3 jars = 6

The least number of dinners that manny can make without any supplies leftover is 6 dinners

Using:

Pasta = 6 dinners / 6 boxes

= 1 package

Pasta = 1 package

Sauce = 6 dinners / 3 jars

= 2 package

Sauce = 2 package
