Y=ab^x
logab=x
log7(1/343)=-3
y=7(1/343)^-3
Answer:
141
Step-by-step explanation:
First, you would round 72.91 to 73 because the number to the right of 7 is greater than or equal to 5, so you would round up. Same goes for 67.526. round both up to 73 and 68 then add. You would get an answer of 141 :)
They all only have 1 term.
Average speed = ![\frac{Total Distance}{Total Time}](https://tex.z-dn.net/?f=%20%5Cfrac%7BTotal%20Distance%7D%7BTotal%20Time%7D%20%20)
Ishan's Speed uphill = 10mph
Time taken = 18 minutes = 18/60 = 3/10 hours
Now distance = rate × time
Distance traveled by Ishaan up hill = 10 × 3/10 = 3 miles
Now returning back home
Distance = 3 miles
Rate = 30 mph
So time taken = distance/ rate = 3/30= 1/10 hours = 1/10 ×60 = 6 minutes.
Now total distance traveled = 3 + 3 = 6 miles
Total time taken = 18 + 6 = 24 minutes = 24/60 = 2/5 hours
Average speed
= ![\frac{6}{0.4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B6%7D%7B0.4%7D%20%20)
= 15 mph
Ishaan's average speed for the entire trip from home to the gift store and back is 15mph
B of course i think i hope
