a jet flying at an altitude of 30000 ft passes over a small plane flying at 15000 feet headed in the same direction the jets fly

Sholpan [36]

The jet has gained on the small plane at the rate of 10 miles per minute, so is flying 600 miles per hour faster. (There are 60 minutes in an hour.)

Since the jet is flying twice as fast as the smaller plane, the small plane's speed is the same as the difference in speed: 600 mph.

The jet's speed is double that, 1200 mph.

small plane: 600 mph
jet: 1200 mph

Which of these expressions is equal to 2(43 - p)?

nirvana33 [79]

Answer:

C. (2×43) - (2×p)

Step-by-step explanation:

The question is 2(43-p)

Which means 2 is multiplying the bracket.

So the answer to the question is 2×43 - 2×p

Which will give us 86 - 2p

So you then solve all the possible answers to see if it the same answer as the one we got

a cake using eggs and potatoes in the ratio of 2 to 5 if he uses sex as how many potatoes will he need

tamaranim1 [39]

When eggs = 2, then potatoes = 5

Eggs: 2
Potatoes: 5

When that is changed to 6 eggs, 2 needs to be multiplied by a number to get 6.

2 * what = 6 or 6/2=

you get the number 3. A fraction is equivalent to a ratio. So if you have 2*3=6 then you need to multiply 5*3 to get the amount of potatoes you need. the answer is 15 potatoes because 5*3=15.
