-15x + 20 + 4 = 69

-15x + 24 = 69

-15x = 69 - 24

-15x = 45

Two investments totallng $47,500 produce an annual income of $3000. One investment ylelds 9% per year, while the other yields 6%
enot [183]

Answer:

The correct answer is "$5000".

Step-by-step explanation:

The given values are:

Two investments totaling,

= $47,500

Annual income,

= $3000

One investment yields per year,

= 9%

Other yield,

= 6%

Let,

  • The amount invested in 9% will be "x".
  • The amount invested in 6% will be "47,500-x".

Now,

⇒  0.09x+0.06(47,500-x)=3000

⇒        0.09x+2850-0.06x=3000

⇒                     0.03x+2850=3000

⇒                                0.03x=150

⇒                                       x=\frac{150}{0.03}

⇒                                       x=5000

Please help! Number 8
Arlecino [84]

as a fraction of 180, m < 1 = 1/ (1 + 3 + 2) * 180 = 1/6  * 180  = 30 degrees

m < 2 = 3*30 = 90 degrees

and m < 3 = 30*2 = 60 degrees

At the Science Museum, there is an exhibition with 150 displays about energy.
tatuchka [14]
<span>1/5
       
This is a matter of elimination. So let's figure out how many of each display there is. 30% of 150 = 0.30 * 150 = 45 displays about electricity. 2/5 * 150 = 0.40 * 150 = 60 displays about renewable energy 1/10 * 150 = 150/10 = 15 displays about gas. The rest of the displays are about nuclear power. So 150 - 45 - 60 - 15 = 30 displays about nuclear power. Since we want a fraction, we get 30/150 But 30/150 isn't in it's simplest form. The largest number that will evenly divide both 30 and 150 is 30. So divide both the numerator and denominator by 30 (30/30)/(150/30) = 1/5 So 1/5 of the displays are about nuclear power.</span>
