Which ratio is incorrectly written in Olivia's conversion?
klasskru [66]

Answer:

Choice 3

Step-by-step explanation:

The third fraction (third refers to the answer number) is incorrect. As written, the cups won't cancel. The correct way to do this is to invert the fraction.

4 tablespoons

===========

1/4 cup

This is an extremely important procedure to know. Make sure you understand what the basis of it is. Often  times in higher physics, you don't have a proper relationships and this method (called dimensional analysis) is the only tool you have to work with.

So each term has at least 1 cancelation that occurs with the prior term. And it is the units that you look to cancel, and that determines which way to put the intermediate steps.

A plane flies 1.4 hours at 150 mph on a bearing of 10. It then turns and flies hours at the same speed on a bearing of . How far
Gnesinka [82]

Answer:

The answer is "1035.76 miles"

Explanation:

The aircraft flies at 120 mph for 1.5 hours at a 10^{\circ} bearing, then flies at the very same speed at 100^{\circ} bearings for 8.5 hours.

However an angle of 100-10 = 90^{\circ} between displacements

First shifts= 1.5 \times 120 = 180\  miles.

Second shift = 8.5\times 120 = 1020\ miles.

These two shifts are at 90^{\circ} and therefore the final shift is:

\to \sqrt{180^2+1020^2}=1035.76 \ miles
