Answer:
Ok thx
Step-by-step explanation:
50 meters
Explanation
you can easily solve this by using a rule of three.
Step 1
Let
![\begin{gathered} 1\text{ milemeter}\rightarrow5\text{ meters} \\ \text{the proportion is} \\ \frac{1\text{ mm}}{5\text{ mt}} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%201%5Ctext%7B%20milemeter%7D%5Crightarrow5%5Ctext%7B%20meters%7D%20%5C%5C%20%5Ctext%7Bthe%20proportion%20is%7D%20%5C%5C%20%5Cfrac%7B1%5Ctext%7B%20mm%7D%7D%7B5%5Ctext%7B%20mt%7D%7D%20%5Cend%7Bgathered%7D)
x represents the length of the actual lawn
then
![\begin{gathered} 10\text{ mm}\rightarrow x\text{ mt} \\ \text{the proportion is} \\ \frac{10\text{ mm}}{\text{xmt}} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%2010%5Ctext%7B%20mm%7D%5Crightarrow%20x%5Ctext%7B%20mt%7D%20%5C%5C%20%5Ctext%7Bthe%20proportion%20is%7D%20%5C%5C%20%5Cfrac%7B10%5Ctext%7B%20mm%7D%7D%7B%5Ctext%7Bxmt%7D%7D%20%5Cend%7Bgathered%7D)
the proportion is the same, so
Step 2
![\begin{gathered} \frac{1}{5}=\frac{10}{x} \\ \text{solve for x} \\ 1\cdot x=5\cdot10 \\ x=50 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Cfrac%7B1%7D%7B5%7D%3D%5Cfrac%7B10%7D%7Bx%7D%20%5C%5C%20%5Ctext%7Bsolve%20for%20x%7D%20%5C%5C%201%5Ccdot%20x%3D5%5Ccdot10%20%5C%5C%20x%3D50%20%5Cend%7Bgathered%7D)
so, the length is 50 meters
Answer:
10.60305932
Step-by-step explanation:
Answer: $22,063.2
Step-by-step explanation:
quarterly means that 4 times per year this interest, the balance can be find by the equation:
A = P*(1 + r/4)^(4*t)
Where P is the initial value, r is the rate of increase (7.3% in this case, but remember that you must use the decimal form; 0.073) and t is the number of years:
so we have:
B = $6,000*( (1 + 0.073/4)^(4*18) = $22,063.2
