Step-by-step explanation:
The cost of each stone sphere is $ 36.81
<em><u>Solution:</u></em>
Given that,
An architect plans to buy 5 stone spheres and 3 stone cylinders
For the same amount, she can buy 2 stone spheres and 6 stone cylinders
Let "x" be that same amount
Let "a" be the cost of each stone sphere
Cost of each stone cylinder = $ 36.81
Therefore,
x = 5 stone spheres and 3 stone cylinders
x = 5a + 3(36.81)
Similarly,
x = 2 stone spheres and 6 stone cylinders
x = 2a + 6(36.81)
Equate both,
![5a + 3(36.81) = 2a + 6(36.81)\\\\5a + 110.43 = 2a + 220.86\\\\5a - 2a = 220.86 - 110.43\\\\3a = 110.43\\\\a = 36.81](https://tex.z-dn.net/?f=5a%20%2B%203%2836.81%29%20%3D%202a%20%2B%206%2836.81%29%5C%5C%5C%5C5a%20%2B%20110.43%20%3D%202a%20%2B%20220.86%5C%5C%5C%5C5a%20-%202a%20%3D%20220.86%20-%20110.43%5C%5C%5C%5C3a%20%3D%20110.43%5C%5C%5C%5Ca%20%3D%2036.81)
Thus cost of each stone sphere is $ 36.81
Answer:
660 mm
Step-by-step explanation:
we know that
The scale factor is ![\frac{1}{15}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B15%7D)
That means
1 unit in the model represent 15 units in the actual
or
1 m in the model represent 15 m in the actual
To find out the height of the model rocket, divide the height of the actual rocket by 15
so
![9.9\ m=\frac{9.9}{15}= 0.66\ m](https://tex.z-dn.net/?f=9.9%5C%20m%3D%5Cfrac%7B9.9%7D%7B15%7D%3D%200.66%5C%20m)
Convert m to mm
Remember that
![1\ m=1,000\ mm](https://tex.z-dn.net/?f=1%5C%20m%3D1%2C000%5C%20mm)
To convert meters to millimeters, multiply by 1,000
so
