7) Option 4

8) Option 1

Step-by-step explanation:

1.31×(10^-5) = 1.131/10⁵

= 1.132/100000

= 0.00001132 (option 4)

7) 3.76×10⁴ + 5.5×10²

10²(3.76×10² + 5.5)

10²(376 + 5.5)

10²(381.5)

10²(3.815×10²)

3.815×10⁴ (option 4)

8) (4×10³)(5×10⁷)

4×10³×5×10⁷

4×5×10³×10⁷

(4×5)(10^(3+7)

(4.5)×(10^(3+7)) (option 1)

That . represents multiplication

Further simplified below:

20×10¹⁰

You are a screenwriter who is writing a script for an hour-long police drama. You have written 20 1/2 pages for act 1 and 5 1/2
finlep [7]

Answer:

You have written 26 pages in total.

Step-by-step explanation:

I always enjoyed adding fractions. Something about it is so... <em>simple.</em>

<u>The problem is basically asking us to add 20 1/2 and 5 1/2 together.</u>

I would first suggest adding both halves together, to make 1.

That way, we're left with 20 + 5 + 1. That seem easier, doesn't it?

Then we would add 20, 5 and 1 together, to get 26 whole pages.

And that, to an extent, is how I did it.

Hope this helps! :D

Fofino [41]
Pythagoras Theroem.
Leg₁²+leg₂²=hypotenuse²

Data:
Leg₁=48
hypotneuse=80

(48)²+ leg₂²=(80)²
2304+leg₂²=6400
leg₂²=6400-2304
leg₂²=4096
leg₂=√4096
leg₂=64

Need answer asap.thanks​

Answer:

0.46=\frac{23}{50}

Step-by-step explanation:

To write any decimal as a fraction you divide by 1 and multiply by a number (ranging from 10, 100, 1000 etc.) that will make 0.46 a whole number, this will explain:

Let x = \frac{0.46}{1}

10x = 10*\frac{0.46}{1} =\frac{4.6}{10}

100x = 100*\frac{0.46}{1}=\frac{46}{100} this is our perfect fraction, now we simplify later

100x - 10x = \frac{46}{100} -\frac{4.6}{10}

90x = \frac{46}{100} -\frac{4.6}{10} =0  this is to confirm both fractions are equal

x is the same as \frac{0.46}{1} as \frac{4.6}{10} as \frac{46}{100} but here x = \frac{46}{100} because a fraction has to have no decimals.

So  0.46 is equal any of these values, as a fraction, on the other hand, it's improperly equal to \frac{46}{100} = \frac{23}{50} here I divided by 2 to bring down the proper fraction. (fraction at its simplest form)

Help me with this question plz. Write the slope intercept form of the equation of each line.
damaskus [11]

Answer:y=-4/3x+2

Step-by-step explanation:

You first figure out the slope by counting the rise and run which is -4/3 in this case and then you look at where it intercepts the y-axis and add it to the end of the equation.
