Find the product. List the units.
3/4h × 19 mi/1/4 h =

Answers

3/4 h times 19mi / 1/4 h
= (3/4)(19/(1/4) (h)(mi/h)
= (3/4)(76) mi
= 57 mi

or, 3/4 hrs ÷ 1/4 hrs = 3 hrs
and 3(19) = 57

or, 19 mi/(1/4)h = 76 mph
you are doing this for 3/4 hrs, so (3/4)(76) = 57

Answer:

57 miles

Step-by-step explanation:

First, do 19 ÷ 1/4. This is the same as 19 × 4 which is 76. Then do 3/4 × 76. 76 ÷ 4 = 19 and 19 × 3 is 57. The unit is miles because the two h's cancel out.

Warm air moves from 30 degrees latitude toward the equator. Which statement best describes what the arrows represent? Air continuously blows away from the equator. Air flows in different directions over long distances. Air moves from regions of low pressure to high pressure. Air circulates in an upward direction, creating surface winds.

Which product is negative? −7⋅(−3)⋅(−5)⋅(−8) −3⋅(−4)⋅(−9)⋅0 −2⋅(−4)⋅8⋅(−1) 6⋅(−2)⋅(−3)⋅1

Answers

Answer:

-2(-4)(8)(-1)

Step-by-step explanation:

The first choice goes like this:

negetive times negetive times negetive times negetive

and negetive times negetive will always be positive. So teh first choice simplified will be positive times positive which is postive of course. so the first choice is a no-no

the second choice goes lke this:

negetive times negetive times negetive times 0

negetive times negetive= positive

positive times negetive= negetive

BUT

negetive times 0 equals 0, and 0 is positive. So 2nd choice is a no-no

the 3rd choice goes like this:

negetive times negetive times positive times negetive

negetive times negetive equals positive

positive times positive=posive

positve times negetive= negetive

so choice 3 is a yes-yes!

p.s if you see theese kinds of problems dont numerically solve it, just think about negetives and positives, hope it helps ! :>

Step-by-step explanation:

Answer: A

Step-by-step explanation:

if possible,find the missing side length labeled with a question mark. if not possible, explain why. on the left at here are 6 inches 6 inches twice . inside the triangle there are 36 inches 36 inches twice. and the in the bottom there is 20 inches

Answers

Answer:

10 inches

Step-by-step explanation:

They're 36 degrees, so corresponding angles are the same, so the middle line is parallel to the bottom line of the triangle.

But the middle line bisects one of the waist lines of the triangle, so this is the middle line, which is equal to half the length of the bottom line

The answer is 10 inches :3
