The composite figure is made up of a triangular prism and a pyramid. The two solids have congruent bases.
kolezko [41]
The correct question is
The composite figure is made up of a triangular prism and a pyramid. The two solids have congruent bases. What is the volume of the composite figure<span>?
</span>
the complete question in the attached figure

we know that
[volume of a cone]=[area of the base]*h/3
[area of the base]=22*10/2-------> 110 units²
h=19.5 units
[volume of a cone]=[110]*19.5/3------> 715 units³

[volume of a triangular prism]=[area of the base]*h
[area of the base]=110 units²
h=25 units
[volume of a a triangular prism]=[110]*25------------> 2750 units³

[volume of a the composite figure]=[volume of a cone]+[volume of a <span>a triangular prism]

</span>[volume of a the composite figure]=[715]+[2750]-------> 3465 units³

the answer is
The volume of a the composite figure is 3465 units³

What are all the solutions of x2 + 3x - 4 = 0?<br> 3 ооооооо<br> DONE
Allisa [31]

Answer:

x = -4, x = 1

Step-by-step explanation:

Now I do not know why you said done, but just saying, if you are done with a question, you should delete it. Now I am just going to assume you knew this and move on with the solution of the problem.

When you factor this equation, you will get (x+4)(x-1).

You can then solve for x using zero product property. The first root is -4 and the second root is 1.

A cylinder of manganese (length 4.00 cm, diameter = 1.00 cm) has a mass of 22.62 g. What is the density of manganese?
Gnom [1K]
Equation for density is mass/volume

Mass=22.62 g

Volume= 22/7 x 1/2^2 x 4

3.14 x 0.5 x 0.5 x 4

=3.14 cm3

Mass/ Volume

22.62/3.14

7.2 g/cm3 is the answer

(^^tap) SOS having a bit of trouble with this problem​
MrRa [10]

Answer:

x = -5.25 or 21/4

Step-by-step explanation:

When break the bracket out, if there is a minus sign in front of the bracket, when we break it out, the sign inside the bracket would become positive:

67 = 18 - (8x - 7)

67 = 18 - 8x - (-7)

67 = 18 - 8x + 7

67 = 18 + 7 - 8x

67 = 25 - 8x or rewrite for easier look: 25 - 8x = 67

25 - 8x = 67

8x = 25 - 67

8x = -42

Divide both side by 8, we got:

x = -42 / 8

x = -5.25 or 21/4

Hope this helped :3
