Lake has a total of $10,000 to invest in two accounts. One account earns 1% simple interest, and the other earns 10% simple inte
Elza [17]

Answer:

  1. $8000 at 1%
  2. $2000 at 10%

Step-by-step explanation:

It often works well to let a variable represent the amount invested at the higher rate. Then an equation can be written relating amounts invested to the total interest earned.

__

<h3>setup</h3>

Let x represent the amount invested at 10%. Then 10000-x is the amount invested at 1%. The total interest earned is ...

  0.10x +0.01(10000 -x) = 280

<h3>solution</h3>

Simplifying gives ...

  0.09x +100 = 280

  0.09x = 180 . . . . . . . subtract 100

  x = 2000 . . . . . . divide by 0.09

  10000 -x = 8000 . . . . amount invested at 1%

<h3>1.</h3>

$8000 should be invested in the 1% account

<h3>2.</h3>

$2000 should be invested in the 10% account

Can someone tell me how to get the answer???
Drupady [299]

Answer:

22.5 cm

Step-by-step explanation:

In the figure attached the graph of the problem can be seen.

Given the triangles are similar then the next proportion must be satisfied:

13.5/9 = 18/12 = x/15 = 1.5

Isolating x, we get:

x/15 = 1.5

x = 1.5*15

x = 22.5 cm

This isn't my work. Thanks to jbiain.

Solve for x then find the measure of the angle given
ololo11 [35]

Answer:

∠ MPQ = 125°

Step-by-step explanation:

∠ LMN and ∠ MPQ are corresponding angles and are congruent , so

5x = 3x + 50 ( subtract 3x from both sides )

2x = 50 ( divide both sides by 2 )

x = 25

Then

∠ MPQ = 3x + 50 = 3(25) + 50 = 75 + 50 = 125°
