Answer:
716in³
Step-by-step explanation:
The first step is to split the full prism into two, separate prisms. That means, we now have to find the volume of the half-a-cylinder, and the other base prism.
For the volume of the half-cylinder, we use the formula πr²h. That means, we do π·5·5·6, which is equal to around 471.24 cubic inches. However, we need to find the volume of half that cylinder, so we divide that answer by two. That should be about <u><em>235.62 cubic inches.</em></u>
For the volume of the other prism, we simply have to do length <em>times</em> height <em>times </em>width, or 6·8·10. That is equal to <em><u>480 cubic inches</u></em>, which is the volume of that prism.
To find the volume of the whole composite figure, you simple have to add the two underlined volumes above.
235.62+480= 715.62in³, or about <em><u>716in</u></em><em>³.</em>

X = number of loads
company A : 20x + 8
company B : 24x + 4
20x + 8 = 20(5) + 8 = 100 + 8 = 108 (company A)
24x + 4 = 24(5) + 4 = 120 + 4 = 124 (company B)
company A charges less
20x + 8 = 20(9) + 8 = 188
24x + 4 = 24(9) + 4 = 220
220 - 188 = $ 32 bucks is saved by using company A
Im pretty sure it'll be 400
Because if you take 20min/3pag then you times it by 60min it would equal 400. Hope I helped
Answer:
Step-by-step explanation:
Keep in mind that to find the average they would do:
Average = Sum of students' ages / number of students
So to solve this question we should firstly find the sum of all their ages.
To do this you multiply 5 by 9 = 45.
This means 45 is the sum of all 5 students' ages.
Next you are given four students have ages 5 , 7 , 8 and 15.
The sum of their ages are: 5 + 7 + 8 + 15 = 35
This means that the final student has age 45 - 35 = 10 years.
3(x-4)=x-6
3x-12=x-6
3x-x = -6+12
2x=6
X= 3
