(2.3 x 10^3)(4.0 x 10^5) =
2300 * 400000 = 920,000,000 or 9.2 x 10^8

or
(2.3 * 4.0)(10^3 * 10^5) =
9.2 * 10^8 = 920,000,000

Hey there, Lets solve this equation together. 

(2.3 x 10^3)(4.0 x 10^5) =

2300 * 400000 = 920,000,000 or 9.2 x 10^8

Also can be written as

(2.3 * 4.0)(10^3 * 10^5) =

9.2 * 10^8 = 920,000,000

Max can mow a lawn in 45 minutes. Jan takes twice as long to mow the same lawn. If they work together, how long will it take the
Licemer1 [7]

Answer:

  c.  30.0 minutes

Step-by-step explanation:

Max mows 1/45 lawns per minute.

Jan takes twice as long (90 minutes per lawn), so mows 1/90 lawns per minute.

Working together, they mow ...

  (1/45 + 1/90) lawns per minute = (2/90 +1/90) lawn/min = 3/90 lawn/min

  = 1/30 lawn/min

Then for one lawn, it takes ...

  (1 lawn)/(1/30 lawn/min) = 30 min

What is the measure of an angle whose sine is√3/2 ? 60 45 30
dem82 [27]
ANSWER

The required angle is
60 \degree

EXPLANATION

Let the angle whose sine is
\frac{ \sqrt{3} }{2}
be
x \degree

Then

\sin(x \degree)  =  \frac{ \sqrt{3} }{2}


We take the inverse sign of both sides to obtain,

x =  \sin ^{ - 1} ( \frac{ \sqrt{3} }{2} )

We use our scientific calculator to evaluate and obtain,

x = 60 \degree
