Answer:


Step-by-step explanation:

Let's look at what 10^100 and 100^10 are as numbers without exponents.

Ten raised to a positive integer exponent is a 1 followed by the number of zeros the exponent tells you. For example, 10^2 is 100, or 1 followed by 2 zeros, just like the exponent 2 tells you. 10^5 is 1 followed by 5 zeros, or 100,000. A googol is 10^100 which is a 1 followed by 100 zeros.

Let's use rules of exponents to understand what 100^10 is.

100^10 = (10^2)^10

To raise a power to a power, multiply powers.

100^10 = (10^2)^10 = 10^20

We know what 10^20 means. It is a 1 followed by 20 zeros.

A googol, 10^100, is a 1 followed by 100 zeros.

100^10 is the same as 10^20 or 1 followed by 20 zeros.

A googol is much, much greater than 100^10.

Answer:

  1. 63 mph
  2. 3 donut holes per kid
  3. $0.70 per pound
  4. $2.25 per km

Step-by-step explanation:

In this context, "per" and "for" mean "divided by."

  1. 630 mi/(10 h) = 63 mi/h
  2. (24 dh)/(8 kid) = 3 dh/kid
  3. $3.50/(5 lb) = $0.70 /lb
  4. $32/(14 2/9 km) = $32/(128/9 km) = $(9/4)/km = $2.25 /km

Two number cubes are rolled and the results are added. What is the probability that the sum is equal to 2?
vodomira [7]

Answer:

Well, assuming that these are cubes labeled 1-6, there is a 1/12 chance of the sum equaling 2, since they would both have to land on 1

Solve the equation for y.<br> 3x + 7y= 29
Oxana [17]

Answer:

y = \frac{29-3x}{7}

Step-by-step explanation:

3x + 7y = 29 ( subtract 3x from both sides )

7y = 29 - 3x ( divide both sides by 7 )

y = \frac{29-3x}{7}

Alla [95]

Answer:

40x30= 1200, 20x15=300, 300/1200= 1/4.

Step-by-step explanation:

You can also visualize it. Imagine a field 40’ long and the boy cut the top 20’ of it but left 20’ of the bottom, he would have cut half of it at this point. Now it’s 30’ wide and he cut the left 15’ of what’s remaining but left the right 15’ uncut. So now there’s a 20’x15’ bottom right corner left uncut. There are 4 sections that are 20’x15’ and he left one out of four uncut, otherwise written as 1/4.
