Are you able to determine the volume of the cube with the information given? (Explain in complete sentences)

Answer:

Step-by-step explanation:

To calculate the speed of each one we proceed as follows:

speed=distance/time

a] Noah's speed:

distance=2.5 miles

time=3/5 hours

speed=(2 1/2)/(3/5)

=(5/2)/(3/5)

=5/2×5/3

=25/6

=4 1/6 mi/hr

Emily's speed

distance=3 3/4 miles

time=5/6 hour

thus

speed=(3 3/4)/(5/6)

=15/4)/(5/6)

=15/4×6/5

=4 1/2 mi/hr

Anna's speed:

distance=3 1/3 miles

time=3/5

speed=(3 1/3)/(3/5

=(10/3)/(3/5)

=10/3×5/3

=5 5/9 mi/hr

Anna was the fastest

The decimal equivalent for 9/5 without doing 9 divided by 5 is 4.5

For conversion from decimal to fraction, we write it in the form a/b such that the result of the fraction comes as the given decimal. Usually, to get the decimal of the form a.bcd, we count how many digits are there after the decimal point (if its finite), then we write 10 raised to that many power as denominator, and the considered number without any decimal point as numerator.

WE are given that Ellena knows that 1/5 written as a decimal is 0.2.

Thus  Ellema use this information to find the decimal equivalent for 9/5 without doing 9 divided by 5

By multiplying 0.2 by 9 we can get the decimal equivalent of 9/5.

0.2 x 9 = 4.5

Hence, the decimal equivalent for 9/5 without doing 9 divided by 5 is 4.5
