Answer:
7 hours and 9 minutes
Step-by-step explanation:
4 hours and 33 minutes is 273 minutes
7 m/s —> 273 minutes
11 m/s —> M
Criss cross to get M
11x273= 7M
3003=7M
M=429 minutes
==> 429 minutes is 7 hours and 9 minutes
It would be 93.75 pounds as the conversion rate goes for dollar bills than pounds
Answer:
200$
Step-by-step explanation:
In this case, we already know the ratio between the savings and the spendings and it's 3:5.
This means that for every 3$ saved, Sam spents 5$.
Then, we only need to do a simply rule of 3, to stablish the amount spended.
If:
120 ---------> 3
X ------------> 5
Solving for X, we have:
120/X = 3/5
X = 120 * 5 / 3
X = 600 / 3
X = 200$
If you want to verify that this calculation is correct, then do the ratio between 120 and 200. If the ratio is 3:5 is correct. Here's the demostration:
120/200 --->simplified by 10: 12/20 ------->simplified by 4: 3/5
Answer:
We have the system:
y > 2*x
y > 3
Now, let's find the limits:
taking y > 3, we can see the limit y = 3.
Now we replace it in the first inequality:
3 > 2*x
3/2 > x.
Then we have that:
y > 3
x < 3/2
Those two inequalities define our system.
So any ordered pair where x is smaller than 3/2 and y is larger than 3, is a solution.
or example:
(1, 3.5) is a solution.
