If cosΦ = 5/13<br><br>what is, sin Φ/sin Φ + cos Φ<br>​
alexandr402 [8]

Answer:

sin Φ/(sin Φ + cos Φ) = 12/17

Step-by-step explanation:

sin Φ = 12/13

then sin Φ + cos Φ = 12/13 + 5/13

= 17/13

So , sin Φ/(sin Φ + cos Φ) = 12/13 ÷ 17/13

= 12/13 × 13/17

= 12/17

A person invested $6,000, some at 7% and the rest at 5%. The income from the 7% investment is equal to the income from the 5% in
8090 [49]

Answer:

The person invested $3500 at 7% and $2500 at 5%

Step-by-step explanation:

We can say that 0,07x+0,05x=6000 because the investment is equal both in one as in another, where x is the income from the investment.

Solving the equation we have:

0,12x=6000\\x=50000

Then to get the incomes:

At 7%: I=0.07*50000\\I=$3500

And at 5%: I=0.05*50000\\I=$2500

Finally we can demonstrate the answer because the  income at 7% + income at 5% are 3500+2500=$6000
