Write 2050000 in scientific notation( with exponents)
2 answers:
So,
We have to write 2,050,000 in scientific notation, which means that the first number must be between 1 and 10 and the second number must be an exponent with a base of 10.
In order to get a number between 1 and 10, we will need to move the decimal point 6 places to the left.
2,050,000 ⇒ 2.05 x

M = hours driven by Maria
c = hours driven by Carlos
since we know that Carlos was driving at an average of 52 mph, then in 1 hour he drove 52 miles, in 2 hours he drove 2*52 miles in "c" hours he drove c*52 miles or 52c.
Maria on the other hand is faster and does 54 mph, in 1 hour she does 1 * 54 miles, and on 2 hours she does 2 * 54 miles and in "m" hours she does m * 54 miles or 54m.
now, we know the total amount of miles they both drove is 217, so whatever "m" and "c" are we know that 54m + 52c = 217.
we also know it took 4.1 for the whole trip, so m + c = 4.1.
so Maria drove for 1.9 hours.
How many hours did Carlos drive for? well, c = 4.1 - m.
c = hours driven by Carlos
since we know that Carlos was driving at an average of 52 mph, then in 1 hour he drove 52 miles, in 2 hours he drove 2*52 miles in "c" hours he drove c*52 miles or 52c.

Answer:
C. 18 inches
Step-by-step explanation:
The median of a trapezoid is the line segment that joins the midpoints of the sides of the trapezoid. It is halfway between the parallel bases, and is parallel to them. It length is the average of the lengths of the two bases:
(15 +21)/2 = 36/2 = 18 . . . . inches
