Given:
The sum of three numbers is 212 .
The ratio of the first to the second is 13:16 and that of the second to the third is 2:3.
To find:
The unknown numbers.
Solution:
We have,
First : Second = 13:16
Second: Third = 2:3
We need to combine these ratios, to get a single ratio for all three numbers.
Second: Third = 2×8:3×8 = 16:24
Now,
First: Second: Third = 13:16:24
Let the first, second and third numbers are 13x, 16x and 24x respectively.
![13x+16x+24x=212](https://tex.z-dn.net/?f=13x%2B16x%2B24x%3D212)
![53x=212](https://tex.z-dn.net/?f=53x%3D212)
![x=\dfrac{212}{53}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B212%7D%7B53%7D)
![x=4](https://tex.z-dn.net/?f=x%3D4)
So, the numbers are,
![First=13x](https://tex.z-dn.net/?f=First%3D13x)
![First=13(4)](https://tex.z-dn.net/?f=First%3D13%284%29)
![First=52](https://tex.z-dn.net/?f=First%3D52)
Similarly,
![Second=16x](https://tex.z-dn.net/?f=Second%3D16x)
![Second=16(4)](https://tex.z-dn.net/?f=Second%3D16%284%29)
![Second=64](https://tex.z-dn.net/?f=Second%3D64)
And,
![Third=24x](https://tex.z-dn.net/?f=Third%3D24x)
![Third=24(4)](https://tex.z-dn.net/?f=Third%3D24%284%29)
![Third=96](https://tex.z-dn.net/?f=Third%3D96)
Therefore, the three unknown numbers are 52, 64, 96.
The answer would be C and D; the squares will be the base of the pyramid as the triangles are placed on each of the square’s sides to compose the 3D square pyramid
If he makes 290 bagels in 2 hours, you have to divide 290/2 to find the rate of change, which is per one. Therefore, the rate per hour is 145 bagels/hour.
You would multiply 145 by 11 to find out how many bagels he makes in 11 hours.
That's 1595 bagels in 11 hours.
