How many milliliters of olive oil (D=0.92 g/mL) have the same mass as 1.80 L of gasoline (D= .74 g/mL)

True [87]

Answer:

1448 mL

Step-by-step explanation:

The mass is the same.

Formula

m = d*V

Givens

Olive Oil

d = 0.92 grams / mL

V = ??

Gasoline

d = 0.74 grams / mL

V = 1.8 L = 1.8 L * (1000 ml / L)

V = 1800 mL

Solution

0.74 * 1800 mL = 0.92 * x Divide both sides by 0.92

0.74/0.92 * 1800 mL = 0.92 *x / 0.92 Combine the left

0.8043 * 1800 mL = x

x = 1448 mL

The volume of Olive Oil needed is 1448 mL

If the point (x,square root 3/2) is on the unit circle, what. is x?

galina1969 [7]

Answer:

$x=\pm\frac{1}{2}$

Step-by-step explanation:

On a unit circle, $(x,y)=(\cos\theta,\sin\theta)$ , so $\sin\theta=\frac{\sqrt{3}}{2}$ in this case. If you look at the attached circle, the only time that the y-coordinate is $\frac{\sqrt{3}}{2}$ is when $x=-\frac{1}{2}$ and $x=\frac{1}{2}$ , which correspond to angles of $\theta=\frac{2\pi}{3}$ and $\theta=\frac{\pi}{3}$ respectively
