Answer:

500-0.01X

Step-by-step explanation:

Total amount invested is X, account 1 pays 4% and account 2 pays 5%. Total invested is the summation of the two interests:

#First Investment at 4%:

I=P(1+i)^1-X, P=X, i=0.04\\\\I=X(1.04)-X\\\\=0.04X

#Interest Earned on 2nd Investment, at 5%.

I=P(1+i)^1-X, P=(10000-X), i=0.05\\\\I=(10000-X)(1.05)-(10000-X)\\\\=10500-1.05X-10000+X\\\\=500-0.05X

I_{net}=I_1+I_2\\\\=0.04X+500-0.05X\\\\=500-0.01X

Hence, the net annual investment is 500-0.01X

What is the simplest form of 2/10?
bezimeni [28]
<span>To get to the simplest form you have to divide numerator and denominator by numbers they can both be divided by, until you get to a fraction where you can't divide both anymore getting an integer as a result.
Here you can only divide by 2 and you get 1/5. That's the simplest form</span>, if you kept dividing you'd get decimals, but the simplest form must be integers.

Answer:

(C) 1/2

Step-by-step explanation:

  • s + 3s = 4s
  • t + 3t = 4t

If 4s is 2 more than 4t, then:

  • 4s = 2+ 4t
  • 4s - 4t = 2
  • 4s/4 - 4t/4 = 2/4
  • s - t = 1/2

(C) is the answer

The length of a rectangular garden is 6 feet less than 3 times its width. The area is 360 square feet. What is the length of the
topjm [15]
Width = w
Length = 3w - 6
Area = 360

Equation Area = wl
w (3w-6) = 360
3w^2- 6w = 360
3w^2 - 6w - 360 = 0
3 (w^2 - 2w - 120)=0
3(w + 10)(w - 12) = 0
w = -10 & 12
l = 3w-6 = 3 (-10)-6= -30 - 6= -36
l = 3w-6 = 3(12) - 6 = 36-6 = 30

Answer: -10 and 12. Yet, since this is a measurement, it must be positive so 12 ft

Sahana sells two products for ₹. 8000 each gaining 8% on one and losing 6% on the other. Find her gain or loss percent in the wh
Margaret [11]

Based on the information given the gain or loss percent on the whole transaction​ is 1%.

<h3>Gain or loss percent: </h3>

First step is to calculate the profit on the whole transaction

Profit=(8%×8,000)-(6%×8,000)

Profit=$640-$480

Profit=$160

Now let calculate the gain or loss percentage on the whole transaction

Gain or loss percentage=160/(8000+8000)×100

Gain or loss percentage=160/16000×100

Gain or loss percentage=1%

Inconclusion the gain or loss percent on the whole transaction​ is 1%.

Answer:

x=35

Angle measurements of the triangle from least to greatest:

35,40,105

Step-by-step explanation:

The sum of the angles of a triangle is 180 degrees.

So we know that 40+3x+x=180.

First step is to combine the like  terms on the left hand side:

40+4x=180

Second step is to subtract 40 on both sides.

4x=140

Third step is to divide both sides by 4:

x=35

The angle that is given is the one that is 40 degrees.

So the angle whose measurement is x is really 35 degrees.

The angle whose measurement is 3x is real 3(35)=105 degrees.

In order from least to greatest we have:

35,40,105
