Lilian has part of $9000 invested at 4% and the remainder at 6%. His annual return on each investment is the same. At what rate

Debora [2.8K]

Given:
Total amount invested = $9,000
interest rates = 4% and 6%

Let x be the part of 9,000.
Note that annual return on each investment is the same.

0.04x = 0.06(9,000 - x)
0.04x = 540 - 0.06x
0.04x + 0.06x = 540
0.10x = 540
x = 540/0.10
x = 5,400

0.04x = 0.06(9,000 - x)
0.04(5,400) = 0.06(9,000 - 5,400)
216 = 0.06(3,600)
216 = 216

total interest for the year : 216 + 216 = 432

Interest = pricipal * interest rate * term
432 = 9,000 * interest rate * 1 yr
432/9,000 = interest rate
0.048 = interest rate

Interest rate would be 4.8% to get the same interest from the whole 9,000.

How many kilometers is it from the main gate to Manatee Springs? (Hint: To convert from

Luda [366]

Answer:

Distance between Main gate M and manatee Spring S,

MS = 6.035 km ≅ 6 km (rounded off)

Step-by-step explanation:

Let the point at Train depot be T. Point at Main gate be M. Point at Bird sanctuary be B. Point at Elephant house be E. Point at manatee Springs be S.

Now, we have two triangles TMB and TSE.

From figure given that, ∠MTB = ∠STE

∠TMB = ∠TSE

∠TBM = ∠TES.

⇒ From AAA similarity, Triangles TMB and TSE are similar.

⇒ $\frac{TM}{TS} = \frac{TB}{TE}$

⇒ $\frac{x}{4200} = \frac{2000}{3500}$

⇒ x = 2400 yds

⇒ Distance between Main gate M and manatee Spring S,

MS = MT + TS = x + 4200 = 2400 + 4200 = 6600 yds

⇒ MS = 6600 yds = 6600 × 0.0009144 km = 6.035 km ≅ 6 km
