Jada traveled 135 miles in 3 hours. Andre traveled 228 miles in 6 hours. Both Jada and Andre traveled at a constant speed. A) Ho
o-na [289]

Given:

Jada traveled 135 miles in 3 hours.

Andre traveled 228 miles in 6 hours. Both Jada and Andre traveled at a constant speed.

To find:

How far did Jada travel in 1 hour?

Solution:

We have,

Distance traveled by Jada in 3 hours = 135 miles

Then,

Distance traveled by Jada in 1 hour = \dfrac{135}{3} miles

                                                           = 45 miles

Therefore, Jada travel 45 miles in 1 hour.

0.5 is a rational number.<br> True<br> False
velikii [3]

Answer:

true

Step-by-step explanation:

Natural numbers are numbers naturally occurring in nature like 1, 2, 3, 4, 5, 6, 7, 8, 9 . . .

Whole numbers are numbers that are whole, like 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 . . . (the only difference is that there is a 0 included)

Integers include negative and positive numbers like -3, -2, -1, 0, 1, 2, 3, 4 . . .

Rational numbers are include all of the above AND anything that can be turned into a fraction, like fractions and decimals (that have an end) like 0.625, -0.5, 1, 4, 1/4, 6/15, 4.8, etc.

So in this case, yes, 0.5 is a rational number.

As part of a new advertising campaign, a beverage company wants to increase the dimensions of their cans by a multiple of 1.12.
olga_2 [115]

Answer:

The new can can hold upto volume of 476.69 cubic centimeters.

Step-by-step explanation:

Diameter of the can = d = 6 cm

Radius of the can = r = 0.5d = 0.5 × 6 cm = 3 cm

Height of the can = h = 12 cm

Company wants to increase the dimensions of their cans by a multiple of 1.12. So, the new dimension will be:

r'= 3 cm × 1.12 = 3.36 cm

h' = 12 cm × 1.12 =13.44 cm

Volume of the = can = V

Volume of a cylinder = \pi r^2h

V=\pi r'^2h'

=3.14\times (3.36 cm)^2\times 13.44 cm=476.6808 cm^3\approx 476.68 cm^3

The new can can hold upto volume of 476.69 cubic centimeters.
