Answer:

x = 240°, x = 300°

Step-by-step explanation:

Using the identity

sin x = $\frac{1}{cosecx}$ = $\frac{1}{-\frac{2}{\sqrt{3} } }$ = - $\frac{\sqrt{3} }{2}$ , then

x = $sin^{-1}$ ( $\frac{\sqrt{3} }{2}$ ) = 60° ← related acute angle

Since sin x < 0 then x is in 3rd / 4th quadrants

x = 180° + 60° = 240°

x = 360° - 60° = 300°

Find how many quarts of 6% butterfat milk and 1% butterfat milk should be mixed to yield 75 quarts of 3% butterfat milk.

Strike441 [17]

Answer:

30 gallons of 6% milk, and 45 gallons of 1% milk.

x=quarts of 6% butterfat

First, write an equation.

0.06x+0.01(75-x)=0.03*75

Multiply both sides by 100.

0.06x*100+0.01*100(75-x)=100*0.03*75

Simplify

6x+75-x=3*75

6x+75-x=225

Solve

5x=225-75=150

5x=150

x=30

75-30=45

So, we need 30 gallons of 6% milk, and 45 gallons of 1% milk.

Solve for x: (x + 50) over 2 = 13x A x = 2 B x = 5 C x = 9 D x = 13

andriy [413]

Answer:

Step-by-step explanation:

Given

$\frac{x+50}{2}$ = 13x

Multiply both sides by 2 to clear the fraction on the left side

x + 50 = 26x ( subtract x from both sides )

50 = 25x ( divide both sides by 25 )

2 = x ⇒ x = 2 → A
