Answer:
81 m²
Step-by-step explanation:
A = 6*10 + 7*6/2
= 60 + 7*3
= 60 + 21
= 81 m²
Answer:
13,92838827718412ft
Step-by-step explanation:
a² + b² = c²
a = 13ft
b = 5ft
169 + 25 = 194
c = √194
c = 13,92838827718412ft
Answer:
Step-by-step explanation:
Length = L.
Width = 2L-3.
A = L * W = 170.
L * (2L-3) = 170.
2L^2 - 3L - 170 = 0,
L = (-B +- Sqrt(B^2-4AC))/2A.
L = (3 +- Sqrt(9 + 1360))/4,
L = (3 +- 37)/4 = 0.75 +- 9.25 = 10, and -8.5. In.
Use positive value: L = 10 In.
Answer:
The exact interest on $5,870 at 12% is $410.9
Step-by-step explanation:
From the information provided we know that
Principal amount: $5,870
Interest rate: 12% -> 0.12
Time: 7 months (From June to December)
When you know the principal amount, the rate, and the time, the amount of interest can be calculated by using the formula:
![I=P\cdot r\cdot t](https://tex.z-dn.net/?f=I%3DP%5Ccdot%20r%5Ccdot%20t)
where P is principal, r is the rate of interest and t is the time in years.
We need to convert the 7 months into 1 year.
![7 \>months \cdot \frac{1 year}{12 months} = \frac{7}{12} year](https://tex.z-dn.net/?f=7%20%5C%3Emonths%20%5Ccdot%20%5Cfrac%7B1%20year%7D%7B12%20months%7D%20%3D%20%5Cfrac%7B7%7D%7B12%7D%20year)
Now we can use the above formula
![I=P\cdot r\cdot t=5870\cdot 0.12 \cdot \frac{7}{12} \\I = 0.12\cdot \frac{7\cdot \:5870}{12}\\I = 0.12\cdot \frac{20545}{6}\\I = \frac{2465.4}{6}\\I = 410.9](https://tex.z-dn.net/?f=I%3DP%5Ccdot%20r%5Ccdot%20t%3D5870%5Ccdot%200.12%20%5Ccdot%20%5Cfrac%7B7%7D%7B12%7D%20%5C%5CI%20%3D%200.12%5Ccdot%20%5Cfrac%7B7%5Ccdot%20%5C%3A5870%7D%7B12%7D%5C%5CI%20%3D%200.12%5Ccdot%20%5Cfrac%7B20545%7D%7B6%7D%5C%5CI%20%3D%20%5Cfrac%7B2465.4%7D%7B6%7D%5C%5CI%20%3D%20410.9)
Therefore the exact interest on $5,870 at 12% is $410.9
