To find their average miles per hour we can divide the total miles by the hour used:
4 2/3 ÷ 1 2/3
=4x3+2/3 ÷ 1x3+2/3
=14/3 ÷ 5/3
In division, when we switch the place of numerator and denominator, we can change it to multiplication which makes the calculation easier as we can factorize the numbers.
=14/3 x 3/5
Factorize 3 in both amounts:
=14/1 x 5/1
=14/5
=2.8 miles/hour
Therefore their average speed is 2.8 miles/hour.
Hope it helps!
Answer:
Please check explanations
Step-by-step explanation:
Here, we want to interpret the meaning of the slope
The slope generally refers to the change in y values with corresponding change in x value
with respect to this question, we can see that the slope is negative
What this mean is that the rate of change in the level of oxygen measured in liters is decreasing with an increase in the time
This means that as more time elapses, more oxygen is used up leading to a decrease in the liters of oxygen present
Answer:
Choice B is correct
Step-by-step explanation:
The given radical division can be expressed in the following form;
Using the properties of radical division, the expression can be expressed in the following form;
Simplifying further yields;
Choice B is thus the correct alternative
The mean of the following dot plot:
Mean: 3
Step-by-step explanation:
0 x 1 = 0
3 x 1 = 3
6 x 1 = 6
(we only add the numbers that only has a dot on the number in the dot plot)
So:
Mean: 0 + 3 + 6 = 9/3 = 3
