Answer:
125 blue vehicles
Step-by-step explanation:
In this question, we are going to estimate the number of vehicles of a specific color given that there are some numbers of both vehicle models present in a sample.
Now to solve this question, we are going to treat the sample numbers as a ratio.
The ratio here is thus 7 black to 5 blue I.e 7:5
We have 300 vehicles, we now want to estimate the number of blue vehicles present.
From the sample ratio, there are a total of 12 vehicles
Now the total number of blue vehicles would be 5/12 * 300 = 125
There are 125 blue vehicles
The answer for that equation would be 281
So the actually surface area can be split up by dif parts....meaning
2 side is 2.7*3.2*2 = 17.28
2 side is 3.2*2.1*2 = 13.44
2 sides is 2.1*2.7*2= 11.34
then u add up the areas = 42.06ft^2
then u look for what is the clossest...and that is 42gt^2
The surface area of a cylinder with circular bases of radius <em>r</em> and height <em>h</em> is equal to the sum of the areas of the two circular faces and the area of the rectangular lateral surface:
<em>A</em> = 2π<em>r</em>² + 2π<em>rh</em>
If you know the height <em>h</em>, then you can solve the quadratic equation for <em>r</em>.
The answer is 74 years. do 11/3=3.67. Then 3.67x20 =73.4 and since that .4 is not a full year you would have to round up to 74
