Answer:

D. Can't be determined

Step-by-step explanation:

You know that the sum of angles in a triangle is 180°, so ...

a + x + 60 = 180

b + y + 40 = 180

Then the difference between 'a' and 'b' is ...

a - b = (120 -x) -(140 -y) = y -x -20

Since the values of x and y are unknown, the relative values of a and b cannot be determined.

<em>Additional comment</em>

If you know the triangles are similar (or congruent) and that the relative angle sizes are as they appear to be, then you could say a=b. There is nothing in this problem statement to indicate that is the case.

Find the nth term of the arithmetic sequences<br> a1=5,d=6,n=11

ki77a [65]

here's the solution,

n = 11
a = 5 ( a = first term )
d = 6 ( d = common difference )

we know,

=》

$nth \: \: term \: = a \: + (n - 1) \times d$

=》

$11th \: \: term = 5 + (11 - 1) \times 6$

=》

$11th \: \: term = 5 + (10 \times 6)$

=》

$11th \: \: term = 5 + 60$

=》

$11th \: \: term = 65$

nth term ( 11th term ) = 65

Jared has some quarters and dimes that total $5.50. If he has 8 more quarters that dimes, how much dimes does Jared have?

MAXImum [283]

Answer: 10 dimes

Solve using system of equations.
q=number of quarters and d=number of dimes
.25q+.10d=5.50 because the total of dimes and quarters is $5.50
8+d=q because there are 8 more quarters than dimes
substitute 8+d for q into the first equation to get .25(8+d)+.10d=5.50
then simplify
2+.35d=5.50
.35d=3.50
d=10 he has 10 dimes

Basit played and online Pin Ball game the first time we got our score of 25000 point then he is called 125000 point and third ti

Marianna [84]

Answer:

Average score per game = 60,000 per game

Step-by-step explanation:

Given:

Points scored in first game = 25,000

Points scored in second game = 125,000

Points scored in third game = 30,000

Find:

Average score per game

Computation:

Average = Sum of observation / Number of observation

So,

Sum of all game = 25,000 + 125,000 + 30,000

Sum of all game = 180,000

Number of games = 3

Average score per game = 180,000 / 3

Average score per game = 60,000 per game
