The main numbers and ratios or rates depending on the problem
Answer:
See explanations below
Step-by-step explanation:
a) 1/4+5/4
= (1+5)/4
= 6/4
= 3/2
b) 23/17+11/17
= (23+11)/17
= 34/17
= 2
c) 16/93+15/93
= (16+15)/93
= 31/93
= 1/3
d) 11/14+23/14
= (11+23)/14
= 34/14
= 17/7
e) 3/16+15/16
= (3+15)/16
= 18/16
= 9/8
f) 1 1/8 + 1 3/8
= 9/8 + 11/8
= (9+11)/8
= 20/8
= 5/2
g) 1 3/10+3 1/10;
= 13/10+31/10
= (13+31)/10
= 44/10
h) 2 3/5+3 2/5
= 13/5+17/5
= (13+17)/5
= 30/5
= 6
Answer:
i think its a 6/7 and 60/70
If it's written correctly, I believe the points are (5 , 140) and (20 , 520). First equation indicates a parabola and the second a line. The parabola crosses the line at two points.
Answer:
d. converges, -25
Step-by-step explanation:
An infinite geometric series converges if the absolute value of the common ratio is less than 1.
Here, the common ratio is 4/5:
| 4/5 | = 4/5 < 1
So the series converges. The sum of an infinite geometric series is:
S = a₁ / (1 − r)
where a₁ is the first term and r is the common ratio.
Here, a₁ = -5 and r = 4/5:
S = -5 / (1 − 4/5)
S = -25
