Mike has $6000 to invest. He invested part of his total into an account earning 6% interest and the rest in an account earning 1

lesya692 [45]

Answer:$4000 was invested into the account earning 6% interest.

$2000 was invested into the account earning 11% interest.

Step-by-step explanation:

Let x represent the amount invested into the account earning 6% interest.

Let y represent the amount invested into the account earning 11% interest.

Mike has $6000 to invest. He invested part of his total into an account earning 6% interest and the rest in an account earning 11% interest. This means that

x + y = 6000

The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal

R represents interest rate

T represents time in years

I = interest after t years

Considering the account earning 6% interest, the interest would be

I = (x × 6 × 1)/100 = 0.06x

Considering the account earning 11% interest, the interest would be

I = (x × 11 × 1)/100 = 0.11y

If at the end of the year, he earned $460.00 in interest, it means that

0.06x + 0.11y = 460 - - - - - - - - - - -1

Substituting x = 6000 - y into equation 1, it becomes

0.06(6000 - y) + 0.11y = 460

360 - 0.06y + 0.11y = 460

- 0.06y + 0.11y = 460 - 360

0.05y = 100

y = 100/0.05 = $2000

x = 6000 - y = 6000 - 2000

x = $4000

Hello, I dont understande this, can someone please explain what it is.

The required diameter of dwarf planet is $10^{6} m$ .

<h3>What is a statement?</h3>

A statement is a declarative sentence that is either true or false but not both. A statement is sometimes called a proposition. The key is that there must be no ambiguity. To be a statement, a sentence must be true or false, and it cannot be both.

Given:

The given statement is the diameter of 3 planet is

planet A= $10^{9} m$ = 1000000000m

planet B= $10^{7} m$ =10000000m

planet C= $10^{8} m$ =100000000m

According to given question we have

A dwarf planet is discovered with a radius is 1/100 times of radius of planet C.

Radius of planet C =100000000/2= 50000000m

Radius of dwarf planet = 1/100 times of radius of planet C.

Radius of dwarf planet = 1/100 * 50000000m

Radius of dwarf planet = 500000 m= $5*10^{5} m$

Diameter of dwarf planet =2*500000 m=1000000 m= $10^{6} m$

Therefore, the required diameter of dwarf planet is $10^{6} m$ .
