It already tells you that he ran 100 meters so what you need to do is convert kilometer to meter and centimeter to meter.
1 kilometer is is 1000 meters. 1 meter is 100 centimeters.
So 5000 centimeters is 50 meters.
Add 100 + 50 + 1000 =
1,150 meters :)
* Craig's answer is not reasonable because to add fractions the denominators must be the same.
** Total distance = 5/8 + 1/2 = 5/8 + 4/8 = 9/8 miles
*** Using the line number to prove the answer:
The line number that represents the problem is in the attached figure.
while the distance between 0 and 1 divided to 8 sections
to represent (5/8) count 5 sections from zero ⇒⇒⇒ point (a)
and to represent (1/2) it is the midpoint between 0 and 1 which mean it is 4 sections but it will be counted from point (a) so, adding 4 sections to point (a) the result will be the point (b)
So, counting from 0 to point (b) will give us 9 sections
and while one section represents (1/8)
So the total distance will be 9 * (1/8) = 9/8 which is agree with the result obtained before
Answer:
=4sqrt(10)
Step-by-step explanation:
The geometric mean of two numbers is sqrt(a*b) where a and b are the two numbers
geometric mean = sqrt(8*20)
=sqrt(160)
= sqrt(16*10)
We know that sqrt(ab) = sqrt(a) sqrt(b)
=sqrt(16) sqrt(10)
=4sqrt(10)
Answer: Choice A
y=2x+3; y=-1/3x+3
==================================================
Explanation:
The left portion of the blue curve is y = 2x+3 but it is only graphed when x < 0 (we could argue that but I'll set that aside for the other portion).
The right portion is the line y = -1/3x + 3 and it's only graphed when
So we could have this piecewise function
Or we could easily swap the "or equal to" portion to move to the first part instead like this
Either way, we're involving the equations mentioned in choice A
