It is estimated that light takes 100,000 years to travel the full distance across our galaxy, the Milky Way. If light travels 3.0 x 100000000 m in 1 second, how long is the Milky Way?
Give your answer in standard form.

Answer 1

Answer:
Well, technically, you've only told us the time to travel across
our galaxy, so we don't have enough information to calculate
anything about its length.

Fortunately, some of us are vaguely aware that our galaxy is
roughly round, at least in its plane. So "across" means its diameter,
and that's the same in any direction through the center.

Relieved, we can now proceed to calculate:

   (3 x 10⁸ meter/sec) x (8.64 x 10⁴ sec/day)
      x (3.65 x 10² day/yr) x (10⁵ years)

      = (3 x 8.64 x 3.65 x 10¹⁹) meters

   = 94.608 x 10¹⁹ meters

   = 946,080,000,000,000,000,000 meters

   (about 587,867,000,000,000,000,000 miles) .

The angle must be appropriately 30° as any other angles mentioned would not be formed out of boxes with stuff in box which formed the angle by leaning on the other one.

A store is selling a pair of sneakers for $80. However, they are having a sale that everything is 15% off. What is the new price of these sneakers after the sale.

Answers

The new price after the sales is $68

Step-by-step explanation:

The cost of a pair of sneakers = $80

Discount / sales offer= 15% off

New price = $80- 15% of $80

15% of $80 = 15 x 80/100

= $12

New price = 80 - 12

= $68

The new price after the sales is $68

The table below shows the blood types of 75 donors after a one-day blood drive. Based on the results, what is the chance that a random donor has type A blood..?Blood Type- O A B AB
Frequency- 31 33 9 2

Answers

Based on the results, the chance that a random donor has type A blood is; 11/25

How to find the Probability?

We are told that there was a survey of 75 blood donors.

Now, we want to find the chance that a random donor has type A blood. From the given table, we see that there are 33 type A blood donors. Thus;

P(donor has type A blood) = 33/75 = 11/25

#SPJ5

What I think the chance that a random donor has type a blood is 44% because there are 33 people in total of 75 that have type A blood type so you simply just divide 33/75 then get .44 which is 44%

Simplify this expression. Assume that y and z are both nonzero. (Question in file/picture)

Type exponential notation with positive exponents.

Answers

Hi, Braydon ! Long time no see. Hope it's all good with you.

First of all, that " -1 " exponent outside the whole thing. That means
invert everything inside. So you're really simplifying:

-21 y⁶ z⁻⁸ / 147 y⁴ z⁴

You can easily write this as the product of 3 separate fractions.
That doesn't change anything, but it makes it a lot easier to handle:

   (-21/147) x (y⁶/y⁴) x (z⁻⁸/z⁴) .

Simplify each one, then just multiply them together again.

First one: (-21/147) Divide top and bottom by 21, and it's (-1/7) .

Second one: (y⁶/y⁴) Divide top and bottom by y⁴, and it's (y²) .

Third one: (z⁻⁸/z⁴) Multiply top and bottom by z⁸, and it's (1/z¹²).

Multiply them:

   (-1/7) x (y²) x (1/z¹²) =

      - y² / 7 z¹² .

That's exactly the same thing as the original expression in the picture,
but it's a lot prettier.
