Answer:
- commercial: 540 mph
- private: 360 mph
Step-by-step explanation:
Time is inversely proportional to speed for the same distance covered. The ratio of commercial to private speeds is ...
2.4 : 1.6 = 3 : 2
If p is the speed of the private plane, then 3/2p is the speed of the commercial plane and the difference of speeds is ...
3/2p -p = 180
1/2p = 180 . . . collect terms
p = 360 . . . . . . speed of the private plane
3/2p = 540 . . . . speed of the commercial plane
The commercial jet flies 540 mph; the private plane flies 360 mph.
Answer:
p ≥ 5
4s + 10p ≤ 100
Step-by-step explanation:
Here, we want to write a system of inequalities
Let the number of bags of soil be s and the number of plants be p
She wants to buy at least 5 plants
mathematically, when something is at least 5, it means greater than or equal to 5
In inequality, we have this as;
p ≥ 5
Secondly, she wants to spend not more than $100; she can spend less but cannot spend more
We have this as;
The number of bags she can buy at $4 per bag is 4 * s = 4s
the number of plants at $10 per one will be;
10 * p = 10p
Adding both should give a cost less than or equal to 100
We have this as;
4s + 10p ≤ 100
So, we have the system of inequalities as;
p ≥ 5
4s + 10p ≤ 100
The answer is 6 months because $1100 - $200 (which he already has) = $900. $900 divided by $150 (which he saves each month) = 6. So it took him 6 months to save up enough.
Positive numbers are always greater than negative numbers.
Therefore 2 > -13. In words, 2 is greater than -13.
