Answer: 32760 ways.
Step-by-step explanation:
To solve this, we first determine the number of ways to select 4 countries from 15, we calculate number of ways to visit these 4 places then we multiply.
Selecting number of ways to choose 4 cities from 15 is by using the combination formula, which becomes 15C4
Number of ways to visit these 4 cities = 4!
Hence,total number of ways of visiting these 4 cities = 15C4 * 4! = 32760ways
Add all the item together:
16 + 28 + 12 + 4
=60 total items
I am assuming that you mean
and
Now, let's look for common factors. The first one is
After we take that out, we are left with 14 and 22. We can take a 2 out of both of these, so the greatest common factors is
It would be 28-10=x because your ending up with 28 after earning 10 you would get that. Hope this works!
Answer:
RPQ = 239°
Step-by-step explanation:
Since SP is a straight line going through the center of a circle, it is a diameter.
We can say that m<SOR and m<ROP are supplementary and add up to 180° because they form a straight line. We can set up an equation:
m<SOR + m<ROP = 180°
We can substitute in the value of m<SOR:
31° + m<ROP = 180°
m<ROP = 149°
Next, we can also say that m<SOQ and m<QOP are supplementary because they form a straight line. Also, since QO is perpendicular to SP, we can say that both m<SOQ and m<QOP equal to 90°.
Now, we can say that m<ROQ (reflex angle) is equal to the sum of m<QOP and m<ROP from angle addition postulate. We can write the equation:
m<ROQ = m<QOP + m<ROP
m<ROQ = 90° + 149° = 239°
The reflex angle <ROQ cuts the arc RPQ, so they would have the same measure. So, arc RPQ = 239°
