Answer:

1 x 10^21

Step-by-step explanation:

The initial number (2 x 10^4) is in scientific notation. Scientific notation must be written as: a X 10^n, where 0<a<10 and n is an integer. In this case, the number in scientific notation is being raised to the power of 5. When we raise a power by another power, we must multiply the power of all the terms by the additional power. In this case, we would get 2^5 x 10^20, this would be 10 x 10^20. Since the value of 'a' needs to be greater than 0 and less than 10, we need to move the decimal to the left and add another power to our 10: 1 x 10^21.

pashok25 [27]

Answer:

Step-by-step explanation:

To find the answer, you'd have to continue tracing the diagonal line until it intersects with the vertical line that corresponds to the number 3.

If you do that, you'll see that in3 boxes, there are 21 footbals.

You can also calculate it mathematically:

If you have 7 balls per box as shown in the graph, you just have to multiply 7 by 3 to know how many balls you'll find in 3 boxes. 7 * 3 = 21.

A slow pitch softball diamond is actually a square 60 ft on a side. how far is it from home to second base?

krek1111 [17]

For this case we have a square whose sides are known and equal to 60 ft.
We want to find the diagonal of the square.
For this, we use the Pythagorean theorem.
We have then:
$d^2 = 60^2 + 60^2

d = \sqrt{60^2 + 60^2}

 d = \sqrt{3600 + 3600}

d = \sqrt{2*3600}

d = 60\sqrt{2}
$
Answer:
from home to second base it is about:
$d = 60\sqrt{2} feet$

Your delivery runs took 7 hours 12 minutes on Monday,6 hours 46 minutes on Wednesday and 6 hours 53 minutes on Friday. What was

blagie [28]

7 hours + 6 hours + 6 hours
=19 hours
12 minutes + 46 minutes + 53 minutes
=111 minutes
=1 hour 51 minutes

19 hours + 1 hour and 51 minutes is 20 hours and 51 minutes. This is the total time.

Average time = total time/number of deliveries

(20 and 51/60) divided by 3
=6.95 hours
= 6 hours and 57 minutes

Which of the following expresses the possible number of positive real solutions for the polynomial equation shown below?

jarptica [38.1K]

In order to figure this out you need to use Descartes Rule. I attached a picture showing Descartes Rule. If the signs changes for when x is positive then the number of times it changes are the possible positive solution. If the sign changes when x is negative then the number of times it changes are the possible negative solutions. With that said the answer is A. View the picture I have attached for the possible + - and imaginary solutions.

Answer = A) One possible positive solution.
