Answer: I'm pretty sure its 1562
Answer:
The sum of 22 terms of given AP = 1562
Step-by-step explanation:
Formula:-
Sum of n terms of AP,
Sₙ= (n/2)[2a + (n - 1)d]
<u>To find the sum of 22 terms</u>
Here. a = 8, d = 6 and n = 22
Sₙ= (n/2)[2a + (n - 1)d]
S₂₂ = (22/2)[2*8 + (22 - 1)*6]
= 11[16 + 126] = 11 * 142 = 1562

Answer:
D. 80 mph
Step-by-step explanation:
d- distance
- d/50= 0.6d/40+0.4d/x
- 1/50= 0.3/20+0.4/x
- 0.4/x= 0.02- 0.015
- x= 0.4/0.005
- x= 80 mph
