Answer:
2
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
X times x is x squared then x times - 2 is - 2x but 4 times x is 4x. So 4x plus - 2x is 2x. Then 4 times - 2 is - 8 put that all together you'll get x^+ 2+2x-8
Answer:
Step-by-step explanation:
<u><em>The complete question is</em></u>
A cone and a triangular pyramid have a height of 9.3 m and their cross-sectional areas are equal at every level parallel to their respective bases. The radius of the base of the cone is 3 in and the other leg (not x) of the triangle base of the triangular pyramid is 3.3 in
What is the height, x, of the triangle base of the pyramid? Round to the nearest tenth
The picture of the question in the attached figure
we know that
If their cross-sectional areas are equal at every level parallel to their respective bases and the height is the same, then their volumes are equal
Equate the volume of the cone and the volume of the triangular pyramid
simplify
we have
substitute the given values
solve for x
since T is the midpoint of SU, then ST = TU.
Answer:
Step-by-step explanation:
<u>Since area of rectangle BCND is given as 90 and one of its side is 10, the other side MUST be 9.</u>
<u></u>
In Rhombus CGNR, CN and GR are congruent (property of Rhombus). Hence GR = 9 as well.
Thus 3GR = 3(9) = 27
First answer choice is right.
