Answer:
The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2
I dont know the exact positions to put the lengths, but tell me if this helps!
Formula
====
d = r * t
Givens
======
d = 2 3/4
t = 1 hour 15 minutes
r = ????
Calculations
==========
You need to convert the 15 minutes to hours.
1 hour = 60 minutes
x hour = 15 minutes
1/60 = x/15
x = 15/60
x = 0.25 hours
so the time = 1 hours + 0.25 hours
t = 1.25 hours
Now you need to do something with the distance.
3/4 mile = 0.75 of a mile
So the distance = 2 + 0.75 = 2.75 miles
Now you are ready for the answer.
d = r * t you are looking for r
2.75 = r * 1.25
r = 2.75/1.25
r = 2.2 miles / hour
Note you could do this with fractions.
2 3/4 = 11/4
1 1/4 = 5/4
r = 11/4 // 5/4 =11/5 = 2 1/5 which is the same thing as 2.2. If your calculator can handle fractions (those kind of calculators cost about 10 dollars in Canada. It should be 8 in the US) that might be the way to do this problem.
Answer: 3.44
Step-by-step explanation:
Step 1: Multiply the whole number by the denominator:
3 × 9 = 27
Step 2: Add the product you got in Step 1 to the numerator:
27 + 4 = 31
Step 3: Divide the sum from Step 2 by the denominator:
31 ÷ 9 = 3.444444
The answer to 3 4/9 in decimal form is displayed below:
3 4/9 ≈ 3.44

Have a nice day noona/hyung.
Answer:
The answer is 3.2 E 3 or 3.2 x 10^3
You move back 3 spaces which is 3.2, since you moved back 3 spaces, you put 3 as the power/exponet.
To be more satisfied, 3.2 is your base number, it is the big number Below the power/exponent. The power/exponent is 3, you moved 3 spaces and you moved to the left, so it is represented as a positive power/exponent.
Hope this helps.
