Answer:
..what answer exactly? (im just gonna put my random answer here lol)
<em>The development of the calander shows they can divde the number of minutes hours days month etc in a year. Development of the pyramids shows geometry and engineering.</em>
We can find this integer using a system of equations. The first thing we look at is the first sentence.
Let's call X The first integer,
Let's call Y the second integer.
So, X+Y=61 and X-Y= 1
Using Substituion on the second equation, we get
X=Y+1
(Now we plug in Y+1 into the second equation for X)
So,
(Y+1)+Y=61
2Y=60
Y=30
So, one of the integers is 30.
Now to find the second, we go back to
X=Y+1
X=30+1
X=31.
So, the integers are 31 and 30.
Hope this helps!
In order to find the median the 1st thing I would do is put the number in order
80,84,87,88,88,90,90,95,98,100
then cross them out Start with left then go the right and so on...
until you get 1 number in the middle left (Since theirs 2 numbers in the middle add them up and divide by two ) 88+90=178 178/2=89
Median = 89
Now in Order to find the mean add up all the numbers and divide by however many numbers their are
You should get 900 then divide by 10 because their were 10 numbers
So Median=89 & Mean=90

Answer:
Step-by-step explanation:
A) Divide both sides of equation by t to isolate r. Then, r = d/t
B) Plugging in the given numbers, solve:
d = distance which is 760,320 yards
r = rate which is unknown
t = time which is 2 hours.
- r = d/t
- r = 760,320 yards / 2 hours
- r = 380,160 yards per hour
C) The conversion from yards to miles, 1 yard = 1760 miles. So, multiply by the previous answer in (B) by the two ratios or just divide:
- 380,160 yards / 1760 miles = 216 miles per hour
D) Use miles in this scenario because of the number of significant digits (yards would require a number in the hundred-thousands).
