2/3 of an hour= 40 minutes
3/4 of 40= 30 minutes
40- 30= 10
So, it took Bethany 10 more minutes to complete her science homework than her math homework.
Answer:
0.333
units³
Step-by-step explanation:
Think process:
The equation is given as y = 
Let, y = f (x)
Therefore, 
We know that the limits are y-axis and x= 3
Y-axis: x= 0
then limits are given as x= 0 and x = 3
Integrating gives:
=
+ C
calculating from x= 0 to x = 3, we know volume is given by 
=
[
]
=
[0.000041136 + 1/3]
= 0.333
units³
Answer:
5/9 is an example of rational number.
Step-by-step explanation:
as the definition of rational number is the number in the form of p/q but the value of denominator q should not be equal to 0. Every integer is a rational number.
Answer:
26.4 km/hr
Step-by-step explanation:
Sofia and Diego drive to work.
For Sofia
We convert miles to km
Sofia drives 72 miles in 1.5 hours.
1 mile = 1.6 km
72 miles = x
x = 72 × 1.6 km
x = 115.2 km
We find the speed in km/hr
Speed = Distance /Time
= 115.2km/1.5 hours
= 76.8 km/hr
For Diego
Diego drives 126 km in 2 hour 30 min.
Speed = Distance/Time
Time = 2 hour 30 min = 2.5 hours
Speed = 126km/2.5 hours
= 50.4 km/hr
The difference between their average speeds in km/h is calculated as:
76.8 km/hr - 50.4 km/hr
= 26.4 km/hr
What you need to do is add the two equations and combine like terms to get h(x). Refer to the photo for a better explanation.
