A) it would be a ratio of 5:1, y=5x
B) if x is 12, it has doubled, so you do the same to y, so it would be 60
<em>To write in standard form, we have to move the decimal point in </em>
<em>3.42</em>
<em> over 3 places to the left since our exponent is 10 3 </em>
<em>This gives us our answer of </em>
<em>0.00342</em>
<em>Hope this helps.</em>
Write and solve an equation of ratios:
15 min 3 racks
---------- = -------------
x 36 racks
Solving this for x: 3x = (15)(36) => x = 180 minutes.
convert this into hours: 180 min 1 hr
------------ * -------------- = 3 hrs (answer)
1 60 min

Step-by-step explanation:
Answer:
The options are not shown, so i will answer in a general way.
Let's define the variables:
h = number of hats
m = number of mugs.
We know that a total of 1000 items were ordered, then:
h + m = 1000
We also know that we have 3 times more mugs than hats, this can be written as:
m = 3*h
Now we have the system of equations:
h + m = 1000
m = 3*h
To solve these, we usually start by isolating one of the variables in one equation and then replace that in the other equation, but in this case, we already have m isolated in the second equation, then we can replace that in the first equation to get:
h + m = 1000
h + (3*h) = 1000
Now we can solve this equation for h, and find the number of hats ordered.
4*h = 1000
h = 1000/4 = 250
There were 250 hats ordered.
