Answer:
Option 1
Option 3
Option 4
Step-by-step explanation:
Inversely proportional means "one quantity increases, the other decreases" or "one quantity decreases, other increases". Inverse relationship, that's it.
Option1:
Since the volume is given as 56 and we know the volume is area of base * height, to keep the volume at constant [56], if height increases, area of base would need to decrease, and vice verse. So inversely proportional.
Option2:
The time spend in plowing a field with a tractor will increase when we area using more fuel. So more fuel used means more time spent. So these are directly proportional, NOT inverse.
Option3:
Since the price is at constant, the amount of length we buy more, the price per one yard HAS to decrease, and vice versa. So, this is inverse relationship.
Option 4:
If the number of identical tranctors increase, it will take less time to plow the set 358 acre farm. And vice versa. So this is inversely proportional as well.
Answer:
7.5
Step-by-step explanation: She can run 5km in 30 mins. That means she can run 1 km every 6 mins. 45/6= 7.5. She can run 7.5 km in 45 mins. Such an amazing feat my chubbiness can't compete with.
Answer:
Step-by-step explanation:
<u>7.5% less than 120 </u>
- 120 - 7.5% of 120 =
- 120(1 - 7.5/100) =
- 120*0.925 =
- 111
Answer:
A
Step-by-step explanation:
Here, we are tasked with finding the order of magnitude.
What we are basically asked here is to write the number in powers of ten.
Thus
4,000,000 = 4 * 10^6
We can see that 10 is raised to the power of six here and thus we can say that the order of magnitude here is simply 6
Answer:
8/9 (simplified)
Step-by-step explanation:
Total marbles = 18
Total of marbles <em>not</em> white = 16
Numerator = 16 / Denominator = 18
= 16/18
= 8/9 (simplified)
