Answer:
I think it would be C
Step-by-step explanation:
First we need to multiply to make the fractions have equal denominators so we can add/subtract.
math: 1/3 x 4/4=4/12
science: 1/4 x 3/3=3/12
Now we can find the time she spent on history (I assume this is what you are looking for)
Total time-math time<span>-science time=history time</span>
12/12-4/12-3/12
=5/12
Amy spent 5/12 of her time working on history.
Perimeter = 2(l+w) or 2(length+width)
So far you have the width, which is 19feet. Since you have two sides of the rectangle which are 19 feet, add 19+19=38
Subtract 62-38 to get 24.
You now have the length of both of the sides combined. So you need to divide 24/2 = 12
The length of the rectangle = 12ft.
Answer: 41.86 miles/hour
Step-by-step explanation:
Use Distance = Speed*Time to find the two missing values with the data that is provided for those two cases [<em>in brackets</em>].
MPH MILES HOURS
50 20 [<em>0.4]</em>
[<em>40</em>] <u>70</u> <u>1.75</u>
Totals 90 miles 2.15 hours
Average = 90 miles/2.15 hours
41.86 mph
The common factors of 32 and 48 are 16, 8, 4, 2, 1,
