We are given the following conversion factor:
![10\text{ miles=}16\text{ km}](https://tex.z-dn.net/?f=10%5Ctext%7B%20miles%3D%7D16%5Ctext%7B%20km%7D)
We are asked to determine how many miles are 140 km. To do that we use the quotient of the conversion factor where the unit we want to convert to is in the numerator and the given unit in the denominator. Since we want to find miles we use the following quotient:
![\frac{10\text{ miles}}{16\text{ km}}\times140\operatorname{km}](https://tex.z-dn.net/?f=%5Cfrac%7B10%5Ctext%7B%20miles%7D%7D%7B16%5Ctext%7B%20km%7D%7D%5Ctimes140%5Coperatorname%7Bkm%7D)
Solving the operations we get:
1. 4n + 28
2. 30-10x
3. 3m+3n
4. 8+2j
Answer:
![15,000\:\mathrm{mm^3}](https://tex.z-dn.net/?f=15%2C000%5C%3A%5Cmathrm%7Bmm%5E3%7D)
Step-by-step explanation:
The composite figure consists of a square prism and a trapezoidal prism. By adding the volume of each, we obtain the volume of the composite figure.
The volume of the square prism is given by
, where
is the base length and
is the height. Substituting given values, we have: ![V=14^2\cdot 30=196\cdot 30=5,880\:\mathrm{mm^3}](https://tex.z-dn.net/?f=V%3D14%5E2%5Ccdot%2030%3D196%5Ccdot%2030%3D5%2C880%5C%3A%5Cmathrm%7Bmm%5E3%7D)
The volume of a trapezoidal prism is given by
, where
and
are bases of the trapezoid,
is the length of the height of the trapezoid and
is the height. This may look very confusing, but to break it down, we're finding the area of the trapezoid (base) and multiplying it by the height. The area of a trapezoid is given by the average of the bases (
) multiplied by the trapezoid's height (
).
Substituting given values, we get:
![V=\frac{14+24}{2}\cdot (30-14)\cdot 30,\\V=19\cdot 16\cdot 30=9,120\:\mathrm{mm^3}}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B14%2B24%7D%7B2%7D%5Ccdot%20%2830-14%29%5Ccdot%2030%2C%5C%5CV%3D19%5Ccdot%2016%5Ccdot%2030%3D9%2C120%5C%3A%5Cmathrm%7Bmm%5E3%7D%7D)
Therefore, the total volume of the composite figure is
(ah, perfect)
Alternatively, we can break the figure into a larger square prism and a triangular prism to verify the same answer:
![V=30^2\cdot 14+\frac{1}{2}\cdot10\cdot 16\cdot 30=\boxed{15,000\:\mathrm{mm^3}}\checkmark](https://tex.z-dn.net/?f=V%3D30%5E2%5Ccdot%2014%2B%5Cfrac%7B1%7D%7B2%7D%5Ccdot10%5Ccdot%2016%5Ccdot%2030%3D%5Cboxed%7B15%2C000%5C%3A%5Cmathrm%7Bmm%5E3%7D%7D%5Ccheckmark)
