Factorize using the difference of squares identity.

a^6 - b^6 = \left(a^3\right)^2 - \left(b^3\right)^2 = \left(a^3 - b^3\right) \left(a^3 + b^3\right)

Then

a^6 - b^6 = 11 \cdot 5 = \boxed{55}

five states in a country have 4 star hotels. Assume the country has 50 states. (a) what fraction of the states can claim at leas
mojhsa [17]

Part A:

Since five states have four-star hotels, only those five states can claim at least one four-star hotel and since there are 50 states, we can write this as 5/50 or 1/10.

Part B:

50 - 5 = 45 states don't have a four-star hotel.

Part C:

45/50 or 9/10 of the states do not have a four-star hotel.

Best of Luck!

160 is what % of 40<br> plz explain
wolverine [178]

Answer:

150%

Step-by-step explanation:

this is because you can make a part to whole ratio where you have x/100 (which would symbolize the percent) and 160/40 (which would symbolize the part) then, multiply 160 by 100 to get 16000 and then divide by 40 to fulfill the x. Hope this helps!

<h3>Answer:</h3>

  7)  0.76 is a rational number

  8)  The list of favorable outcomes is {orange pop #1, orange pop #2}.

<h3>Step-by-step explanation:</h3>

7) The product 0.4 × 1.9 is 0.76. This is not an integer, whole number, or natural number. It is a decimal fraction of finite length, so is a rational number.

mya has ballet lessons every sixth day and swimming every fourth day. today she has both lessons. in how many days will mya have
ra1l [238]
To determine when Mya will have both lessons again on the same day, you will list the multiples of each number of days because to show every 4 or 6 days, you will count by 4's and 6's.

When you get to the first number that is the same, that will be the next time she will have both lessons again.  This is called the least common multiple (LCM).

4, 8, 12, 16, 20, ...
6, 12, 18, 24

In 12 days she will have both lessons again.
