Answer:
h = 13
Step-by-step explanation:
Given the area of a triangle as 84.5 .
The correct value to complete the formula to calculate for the height h is 13 .
Area of a triangle = 1/2 b x h
b = base
h = height
Using the above formula
84.5 = 1/2 x 13 x h
84.5 = 13/2 x h
84.5 = 6.5 x h
84.5 = 6.5h
Divide both sides by 6.5 to get h
84.5/6.5 = 6.5h /6.5
13 = h
h = 13
The best way to randomly choose the 100 families would be to allow a random number generator to come up with 100 families within a 50 radius of the amusement park.
Using this method would ensure that it is more randomised & not limited to people who come at a specific time or are in a specific area as well as it not be affected by subconscious bias of people when selecting people to survey.
Answer:
=Barlow by 181 boys
Step-by-step explanation:
lets calculate the no of boys in Barlow
=4/9×873=388
388 boys
in Willow school
to bet no of boys
3/3-2/3=1/3
1/3×620=207(in a calculator it will give you decimals so i rounded of to the nearest whole no.)
388-207=181
1 day = 750 m
1 * 7 = 750 * 7
7 days = 5250 m
Now, since 1 km = 1000 m, this means in order to convert from meters to kilometers you must divide by 1000
5250 / 1000
= 5.25 km
Or, you could do the hard way by going to wolfram alpha / google and typing 5250 m to km.
Hope this helps!
