Can someone help me pls
Leviafan [203]

Answer:

Step-by-step explanation:

0.75 feet / day [ 1 day / 24 hours] * [12 inches / 1 foot]

This process is called dimensional analysis. The trick it uses is to cancel out units (like feet or days ) where possible. In this case, 1 day is going to cancel out and leave behind 24 hours. 1 foot will cancel out and leave behind 12 inches.

It is well worth learning how to do this, because the process is done in the higher sciences.

So what you are left with is

0.75 * 12 inches / 24 hours

0.75 inches /hour * 1/2

0.375 inches / hour.

Find the size of each interior angle of a regular hexagon
Serhud [2]

Answer:

Each interior angle = 180° -60° = 120°

Step-by-step explanation: We know that the three angles in a triangle, add up to 180°, and all the three angles are 60° in an equilateral triangle. The total number of angles of an enclosed space is 180° (n-2) where in is the number of sides.
A hexagon has six sides, so: s= 180° (6-2)

s= 180° x 4

s= 720°

now since in a regular shape, each interior angle is equal. We just divide the total interior angle with a number of sides

6.

720° divided by 6 is equal to 120°

Peggy had four times as many quarters as nickels. She had $2.10 in all. How many nickels and how many quarters did she have?
kari74 [83]
For the answer to the question above, 
and we are told that there are "four times as many quarters as nickels"
this translates to
q = 4n

0.05n + 0.25q = 2.10
and
q = 4n
are your two equations that could be used to solve this problem


if you would like to know how many nickels and how many quarters there are, plug in q = 4n into the first equation and get
0.05n + 0.25(4n) = 2.10
then I would stop here
because I didn't see the choices. So the answer is 4n
