A train travels 45 feet in 1/10 if a second. How far will it travel in 3.5 seconds

Answers

Answer 1

Answer:

The distance covered by the train in 3.5 seconds will be 1575 feet.

What is speed?

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

A train travels 45 feet in 1/10 in a second.

Then the speed will be

Speed = 45 / (1/10)

Speed = 45 x 10

Speed = 450 feet per second

The distance covered by the train in 3.5 seconds will be

Distance = 450 x 3.5

Distance = 1575 feet

Answer 2

Answer:

Answer:

1575 ft

Step-by-step explanation:

Convert 1/10 to decimal to make the math simpler.

1/10 = 0.1

Divide 3.5 by 0.1.

3.5/0.1 = 35

Multiply 35 by 45.

35 × 45 = 1575

The train will travel 1575 feet in 3.5 seconds.

Answers

Answer:

7,000,000,000

Step-by-step explanation:

since the closest number is less than 5 (1<5) you round down making the nearest billion 7

Answer:

7,000,000,000 OR 7 Billion

Step-by-step explanation:

Since the 1 is millions place and its less than 5, you need to round down meaning that 7,125,000,00 rounded to the nearest billion is 7 billion.

- Use the unit circle to evaluate
the six trigonometric functions
of theta= 4pi

Answers

The six trigonometric functions, $\sin (\pi)/(4) =(1)/(√(2))$ , $\cos (\pi)/(4) =(1)/(√(2))$ , $\tan (\pi)/(4) =1$ , $\cot (\pi)/(4) =1$ , $\sec (\pi)/(4) =√(2)$ and $\csc (\pi)/(4) =√(2)$ .

Step-by-step explanation:

We have,

$(\pi)/(4)$

To write the six trigonometric functions = ?

$\sin (\pi)/(4) =(1)/(√(2))$

$\cos (\pi)/(4) =(1)/(√(2))$

$\tan (\pi)/(4) =1$

$\cot (\pi)/(4) =1$

$\sec (\pi)/(4) =√(2)$

$\csc (\pi)/(4) =√(2)$

∴ The six trigonometric functions, $\sin (\pi)/(4) =(1)/(√(2))$ , $\cos (\pi)/(4) =(1)/(√(2))$ , $\tan (\pi)/(4) =1$ , $\cot (\pi)/(4) =1$ , $\sec (\pi)/(4) =√(2)$ and $\csc (\pi)/(4) =√(2)$ .
