Mathematics

Helen [10]2 years ago

Answer:

2.70 hours to travel 180 mi.

Step-by-step explanation:

The distance traveled (d) varies directly as the time (t) of travel, by the following formula:

s = \frac{d}{t}

In which s is the velocity.

It takes 63 min to travel 70 mi.

So i am going to find the velocity in miles per minute

s = \frac{70}{63} = 1.11

how many hours would it take to travel 180 mi?

I am first going to find the time in minutes, then divide by 60 to pass to hours.

s = \frac{d}{t}

st = d

t = \frac{d}{s}

t = \frac{180}{1.11}

t = 162.16

It takes 162.16 minutes = 162.16/60 = 2.70 hours to travel 180 mi.

Near the equator, the earth rotates approximately 34 kilometers every 32 seconds. what is the speed of earth's rotation near the
viktelen [127]

Answer:

Step-by-step explanation: The earth rotates 34 km every 32 seconds. We can simplify this by dividing both sides by 32. Now, we have 34/32 km every 32 seconds. Now, to further simplify this, we need to convert 34/32 to a mixed number 34/32 = 1 2/32 which then can be simplified to 1 1/16. So, near the equator, the speed of Earth's rotation is 1 1/16 km per second.

when Best Buy sells a Samsung 32" flat screen television for $219.99, does the 32" represent the length, width, or diagonal of t
Varvara68 [4.7K]

Answer:

Diagonal

Step-by-step explanation:

The measure of a television is always indicated by providing the length of the diagonal, in inches.

In fact, the actual length and height of a 32" tv are:

- Length:

L = 27.9 inches

- Height:

h = 15.7 inches

For an object with a rectangular shape, such as the TV, the diagonal of the object can be found by using Pythagorean's theorem:

d=\sqrt{L^2+h^2}

where

L is the length of the rectangle

h is the height of the rectangle

Substituting the values above, we find:

d=\sqrt{(27.9)^2+(15.7)^2}=32.0 in.

Which corresponds to the diagonal of the TV.
