Answer:
25 meters
Step-by-step explanation:
30 km/hr = (30 km/1 hr)*(1000 m/1 km)*(1 hr/60 min)*(1 min/60 sec)
30 km/hr = (30*1000*1*1)/(1*1*60*60) meters per second
30 km/hr = 8.3333333333 m/s (approximate)
----------
The speed or rate is r = 8.3333333333 meters per second approximately, and the time is t = 3 seconds, so,
distance = rate*time
d = r*t
d = 8.3333333333 * 3
d = 24.9999999999
Due to rounding error, the true answer should be d = 25. We can see this if we opted to use the fraction from of 8.3333... instead of the decimal representation which isn't a perfect exact measurement.

Step-by-step explanation:
AP EX Confirmed
Answer:
To do this you do:
2 divides by 9 which is 0.222
Step-by-step explanation:
Let m be the price of 1 baby mice
Let p be the price of 1 baby python
Given,
as equation 1.
and
as equation 2
From here we can easily use elimination method
for solving simultaneous equations.
Use Equation 1 - equation 2 to eliminate m to find p.
Substitute p into equation 1.
therefore 1 baby mice cost $4.50 and 1 baby python costs $45.
Answer:
$51.36
$77.04 i think
Step-by-step explanation:
Multiply the cost of the number of pairs of jeans by the sales tax amount, 7%.
cost of 2 pairs: 48 + 7/100 x 48 = $51.36
cost of 3 pairs: 72 + 7/100 x 72 = $77.04
