The school cafeteria has eight very large cans of tomato sauce for making pizza.

BlackZzzverrR [31]

Answer:

The Answer is that there is less than 50 Liters of sauce in the 2 cans.

Step-by-step explanation:

Given: 2 Gallons of sauce

How many Liters in 2 gallons?

There are 3.7854 liters per gallon. Multiply to get the total liters in 2 gallons:

2 * 3.7854 = 7.5708 Liters.

7.5708 is less than 50 Liters. Therefore, there is less than 50 Liters in the 2 gallons of sauce.

Hope this helps!! Have an Awesome day!!! :-)

If sec theta = - √30 / 3, find cos theta.<br> if sin(-theta) = -0.97, find cos (π/2 - theta).

Cloud [144]

Step-by-step explanation:

$\cos \theta = \frac{1}{ \sec\theta } = - \frac{3}{ \sqrt{30} } = - \frac{3 \sqrt{30} }{30} = - \frac{ \sqrt{30} }{10}$

$\cos( \frac{\pi}{2} - \theta )= \cos \frac{\pi}{2} \cos \theta + \sin \frac{\pi}{2} \sin \theta$

Note that

$\sin( - \theta) = - \sin \theta$

$\cos \frac{\pi}{2} = 0 \: \: \: \: \: \sin \frac{\pi}{2} = 1$

Therefore,

$\cos( \frac{\pi}{2} - \theta ) = 0.97$
