6 x 10^-2 is how many times a large as 2 x 10^-8?

Diano4ka-milaya [45]

Answer:

the number $6\,\,\,10^{-2}$ is three million times larger than $2\,\,\,10^{-8}$

Step-by-step explanation:

To answer this, just do the quotient of the first one over the second one, and use the rules for quotient of exponential expressions of the same base:

$\frac{6\,\,\,10^{-2}}{2\,\,\,10^{-8}} =\frac{6}{2} \,\frac{10^{-2}}{10^{-8}} =3\,\,\,10^{-2+8}=3\,\,\,10^6=3000000$

So the answer is: the number $6\,\,\,10^{-2}$ is three million times larger than $2\,\,\,10^{-8}$

Two ships leave port at the same time. One travels at 5km/h on a bearing of 046°. The other travels at 9km/h on a bearing of 127

inn [45]

Answer:

You do not sail on a "bearing". You sail on a "heading". A bearing is a direction you look at another ship or a lighthouse or whatever. " That tanker bears south by Southwest for example. Math texts drive me nuts. Landlubbers.

Anyway:

first ship east (+x) distance = 10 cos 46 = 6.95 km

first ship north (+y) distance = 10 sin 46 = 7.19 km

180 - 127 = 53 degrees north of west

second ship east distance = -18 cos 53 = - 10.8 km

second ship north distance = 18 sin53 = 14.4 km

difference east-west = 6.95 + 10.8 =

difference north south = 14.4 - 7.9 =

3. A dealer altered his trade discount from 15% to 10%. By whatpercent was selling price altered?

BabaBlast [244]

Answer:

Regular selling price (price before discount) 100%.

Price after trade discount of 15% is 85% of regular selling price..

Price after trade discount reduced to 10% is 90% of regular selling price.

By reducing the trade discount from 15% to 10% meant increasing the selling price by 5% of the selling price before applying the trade discount.

Answer:

-2

Step-by-step explanation:

Hey there!!

if we evaluate the expression it will look like :

3x + 14 = 8

and if we solve it:

3x+14=8

Step 1: Subtract 14 from both sides.

3x+14−14=8−14

3x=−6

Step 2: Divide both sides by 3.

3x/3 = -6/3

x= −2
