Answer:
135
Step-by-step explanation:
An arithmetic sequence is a list of numbers with a definite pattern.
In this case, the numbers increase at a constant rate of 6.
The first term of the sequence is 81, the second term is 87, and the third term is 93.
To get the tenth term, you can simply count them each,
81, 87, 93, 99, 105, 111, 117, 123, 129, 135
The tenth term of the arithmetic sequence is 135.
11 is the average...that i get.
Answer:
70%
Step-by-step explanation:
well first you have to take put 90 over 300, times 100
<u>90</u> <u>100</u> = 30%
300 × 1
That gives you the percentage that is spoken today.
Then you have to take away that answer from 100%
100%
<u>-</u><u> </u><u> </u><u>30</u><u>%</u>
70 %
The angles of a triangle always equal to 180 degrees.
Knowing this, you can solve this by this equation
Angle A + Angle B + Angle C = 180
43 + 85 + Angle C = 180
Angle C = 180 - 43 - 85
Angle C = 52
Answer:
X=1/6 Y=0
Step-by-step explanation:
If Y= 6x-1, substitute Y on the first equation
7x+3(6x-1)=7/6
7x+18x-3=7/6
25x=(7/6)+3
25x=25/6
x=1/6
Then substitute X on the second equation
Y=6(1/6)-1
Y=0
