Step-by-step explanation:
Answer:
15.59 cm^2
Step-by-step explanation:
Given formula for area= √(3s^4)/4
We have, a=6cm
Area= √(3s^4)/4 = √(3*6^4)/4 =√(3*1296)/4 =√3888/4 ≈ 62.35/4 ≈ 15.59 cm^2
Answer:
$6500
Step-by-step explanation:
A bank loaned out $18,000
Let x be the part of amount at the rate of 6 % per year
So, Remaining amount = 18000-x
So, the part of amount at the rate of 14 % per year = 18000-x
the interest received in one year totaled $2000
Formula : ![SI = \frac{P \times R \times T}{100}](https://tex.z-dn.net/?f=SI%20%3D%20%5Cfrac%7BP%20%5Ctimes%20R%20%5Ctimes%20T%7D%7B100%7D)
P is the principal
R = rate of interest
T = Time
SI at 6%+SI at 14% = 2000
![\frac{x \times 6 \times 1 }{100}+\frac{(18000-x) \times 14 \times 1 }{100}=2000](https://tex.z-dn.net/?f=%5Cfrac%7Bx%20%5Ctimes%206%20%5Ctimes%201%20%7D%7B100%7D%2B%5Cfrac%7B%2818000-x%29%20%5Ctimes%2014%20%5Ctimes%201%20%7D%7B100%7D%3D2000%20)
![\frac{-2 }{25}(x-31500)=2000](https://tex.z-dn.net/?f=%5Cfrac%7B-2%20%7D%7B25%7D%28x-31500%29%3D2000)
![x=6500](https://tex.z-dn.net/?f=x%3D6500%20)
Hence the bank loan out at 6% is $6500
Answer:
1 solution
Step-by-step explanation:
There is exactly one solution because when both lines are graphed, they intersect at only one point, (1.5,-1).
