Answer: Yes, It will be equal in 2.2 years

Step-by-step explanation:

Hi, to answer this question we have to write an equation for the mileage of Elena and Marc.

Elena = 15,000+ 23,000x

Marc= 46,000+ 9,000x

Wheres x is the number of years

So, if both have the same mileage

15,000+ 23,000x = 46,000+ 9,000x

Solving for x

23,000x-9,000x =46,000-15,000

14,000x = 31,000

x = 31,000/14,000

x = 2.21 years

Two urns each contain green balls and blue balls. urn i contains 4 greenballs and 6 blue balls, and urn ii contains 6 green ball

Lemur [1.5K]

1st urn....4 green balls, 6 blue balls.....10 total balls....probability of drawing a blue ball in urn 1 is : 6/10 reduces to 3/5

2nd urn...6 green balls, 2 blue balls....8 total balls...probability of drawing a blue ball in urn 2 is : 2/8 reduces to 1/4

probability both balls are blue : 3/5 * 1/4 = 3/20 <==

Answer:

70° (number in the blank at the bottom)

Step-by-step explanation:

You need to know the meaning of "complement of an angle."

Complementary angles have a sum of 90°. So, the complement of 20° is the angle that makes the total 90°. It is 70°.

The line at the bottom of the figure tells you how to work the problem. It says "the cosine of an angle is the sine of its complement." If you put numbers in this statement, it tells you ...

the cosine of 20° is the sine of 70°

So, the answer to the question at the top of the page is ...

look up the value of sin(70°) in the table
