Answer: there are 70 dimes and 40 quarters.
Step-by-step explanation:
A dime is 10 cents
A nickel is 5 cents
A quarter is 25 cents
Let x represent the number of dimes at the bottom.
Let y represent the number of quarters at the bottom.
The city park employee collected 1,850 cents in nickels, dimes, and quarters at the bottom of a wishing well. If there were 30 nickels, it means that
10x + 25y + 30 × 5 = 1850
10x + 25y = 1850 - 150
10x + 25y = 1700- - - - - - - - -1
There is a combined total of 110 dimes and quarters. It means that
x + y = 110
Substituting x = 110 - y into equation 1, it becomes
10(110 - y) + 25y = 1700
1100 - 10y + 25y = 1700
1100 + 15y = 1700
15y = 1700 - 1100
15y = 600
y = 600/15
y = 40
x = 110 - y = 110 - 40
x = 70

Answer:
27
Step-by-step explanation:
Given the ratio 3 : 9
and 9 : ?
note that 3 × 3 = 9, thus 9 × 3 = 27
3 : 9 = 9 : 27
The simplified function of
is ![f(x) = \frac {3^x}4(\sqrt[3]{4})^x](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%20%7B3%5Ex%7D4%28%5Csqrt%5B3%5D%7B4%7D%29%5Ex)
<h3>How to simplify the base function?</h3>
The function is given as:
![f(x) = \frac 14(\sqrt[3]{108^x})](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%2014%28%5Csqrt%5B3%5D%7B108%5Ex%7D%29)
Expand 108
![f(x) = \frac 14(\sqrt[3]{27 * 4})^x](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%2014%28%5Csqrt%5B3%5D%7B27%20%2A%204%7D%29%5Ex)
Take the cube root of 27
![f(x) = \frac 14 * 3^x(\sqrt[3]{4})^x](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%2014%20%2A%203%5Ex%28%5Csqrt%5B3%5D%7B4%7D%29%5Ex)
Evaluate the product
![f(x) = \frac {3^x}4(\sqrt[3]{4})^x](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%20%7B3%5Ex%7D4%28%5Csqrt%5B3%5D%7B4%7D%29%5Ex)
Hence, the simplified function of
is ![f(x) = \frac {3^x}4(\sqrt[3]{4})^x](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%20%7B3%5Ex%7D4%28%5Csqrt%5B3%5D%7B4%7D%29%5Ex)
