Answer: f(x) = 9 pesos if 0km ≤ x ≤ 4km
f(x) = 9 pesos + (x - 4km)*0.75 pesos if 4km ≤ x
Step-by-step explanation:
Ok, we know that:
For the first 4km, we have a fixed price of 9 pesos.
For any km after the 4km mark, we have an extra of 0.75 pesos.
Then if x is the number of kilometers, we can write this as:
f(x) = 9 pesos if 0km ≤ x ≤ 4km
f(x) = 9 pesos + (x - 4km)*0.75 pesos if 4km ≤ x
Where we use (x - 4km) because we start counting after the 4km mark.
Answer:
Here we have the case where:
"one chip is eaten in 1/4 mins."
(that means unit rate, the amount of a given variable that we need to do a unit of another variable)
Then the unit rate would be:
4 chips per minute.
Or, in a more mathematical way to write this:
4 chips/min.
Now we could write this in other units, for example.
We know that 1 min = 60s.
Then we have that (1/4) min = 60s/4 = 15s.
Then we have the unit rate:
1 chip every 15 seconds, or:
(1/15) chips/second.
Now, the variable in this case is time, t = time, let's multiply bot our unit rates by the same amount of time, and see if we have the same outcome.
Let's use t = 2 min.
1) (4chips/min)*2min = 8 chips.
2) ((1/15) chips/second)*2min
First, 2 min = 120 seconds.
((1/15) chips/second)*2min = ((1/15) chips/second)*120seconds = 8 chips.
So both unit rates are equivalent.
Answer: 580
Step-by-step explanation:
A fence is usually a rectangle shape in these questions
Perimeter of a rectangle is P = 2l + 2w
P = 2(170) + 2(120) = 580

Hope this helps!! :)
We can use the is/of=p/100 method for this problem. Since it's 15% off, this would mean that the bill is 85% of what it was initially. Plug the values into the is/of=p/100 formula.
36.72/x = 85/100
Solve for x.
x=36.72/0.85
x=43.2
So, the bill was $43.20 before applying the voucher discount of 15% off.
The answer is 244.80
You can calculate this by taking 36.72 and dividing it by 0.15 (15%). You would do this because it is the opposite of multiplying an original number by 0.15 (15%) to get 36.72.
