Answer:
(-4,-1)
Step-by-step explanation:
Look at where the lines on the graph intersect, then find the point.
The conversion from yards to feet and feet to miles are given.
You need to convert seconds to hours.
The conversion already given for time has 1 minute as the denominator, so the next conversion fraction needs to have minutes as the numerator.
The answer would be: A) 60 min/ 1 hour
Answer:
9a = 11a - 2a
9a = 9a
Step-by-step explanation:
9a = 11a - 2a
11 - 2 = 9
Similarly, 11a - 2a = 9a
Eleven minus two equals nine. Similarly, 11a minus 2a equals 9a. You can subtract them because they both have the same variable <u><em>a</em></u>.
I think the answer would be 0.16
That's geometric sequence
T7 = T5*r^2 = T5+1920
r = 2, so
4*T5 = T5 + 1920
3T5 = 1920
T5 = 640
640 = 2^4 * 40
So, a=40 and the sequence is
40 80 160 320 640 1280 2560 5120 10240 20480 40960 ...
Note that 2560 = 640 + 1920
