<h3>
Answer: 96 cubic feet (choice D)</h3>
=======================================================
Explanation:
The triangular face has area of base*height/2 = 8*2/2 = 16/2 = 8 square feet.
Multiply this with the depth of the prism to get 8*12 = 96 cubic feet
----------
For any prism, the volume formula is
V = (area of base)*(depth of prism)
The term "depth" can be replaced with "height" and it's the same idea.
In this problem, we have a triangular prism because the parallel sides are triangles.
Basically
Circumference = 2 * pie * radius
To get the radius u need to measure the circles distance. For example I measured a circular mirror and the distance was 10cm. This is the diameter. To get the radius I’ll divide by 2 because the radius is from the centre of the circle to the edge. So, 10 divided by 2 = 5cm. The radius is 5cm. Now,
Circumference = 2 * pie * r
r = 5. Pie = 3.14
Circumference = 2 * 3.14 * 5
= The answer
****pie is always 3.14
I hope you understood
Answer:
40
Step-by-step explanation:
a+b=c
a=girls
b= boys
c= total
the statement tell us:
4/5 of a class is girls:
a=(4/5)*c
boys=b=8
c=a+b
so we have:
c=(4/5)*c + 8
c-(4/5)*c=8
(5c-4c)/5 = 8
c/5=8
c=8*5
c=40
total=40
Answer:
The leading coefficient is 1 and the linear term coefficient is an even number
Step-by-step explanation:
Leading coefficient must be one for the application of completing square method. If the completing square is not one than we must apply other methods like Ac method, quadratic formula to solve the equation. To solve the equation with completing square the numerical value must be on other side of the equation. In this method we multiply linear term’s coefficient with one-half and square it therefore, completing square is suitable method for the equation having leading coefficient is 1 and linear coefficient is even.
