The length of one rope = 9 in

Number of ropes Jared have = 2.

The total inches of rope does Jared have will be calculated as under -

We can add the length of two ropes as = 9 in + 9 in = 18 in

Or we can do it by other method as well.

The other method is by multiplying -

The total inches of rope does Jared have = The length of one rope × Number of ropes Jared have

The total inches of rope does Jared have = 9 in × 2 ropes = 18 in

Andrej [43]

Answer:

LHS.= Sin 2x /( 1 + cos2x )

We have , sin 2x = 2 sinx•cosx

And. cos2x = 2cos^2 x - 1

i.e . 1+ cosx 2x = 2cos^2x

Putting the above results in the LHSwe get,

Sin2x/ ( 1+ cos2x ) =2 sinx•cosx/2cos^2x

=sinx / cosx

= Tanx

.•. sin2x/(1 + cos2x)= tanx

Our hearts beat approximately 70 times per minute. Express in scientific notation how many times the heart beats over a lifetime

earnstyle [38]

Answer:

2.69 x $10^{9}$

Step-by-step explanation:

We are given the heart's speed - 70 bpm

We count the number of minutes in 73 years :

1 year = 365 days
1 day = 24 hours
1 hour = 60 minutes
73 x 365 x 24 x 60 = 38,368,800 minutes

We multiply the heart's bpm with 73 years worth of minutes

38,368,800 x 70 = 2,685,816,000

Write the number in scientific notation = 2.68581 x $10^{9}$ ≈ 2.69 x $10^{9}$
