For what measurements? if you’re talking like science stuff i use King Henry Drank My Delicious Chocolate Milk for Kilo Hecto Decka, middle, Deci, Centi, Milli. middle is your unit!
the answer is a) 0.29 bc of SOHCAHTOA if u didn’t learn this then i can see why u were confused but it’s asking for tan which is TOA tan= opposite/adjacent so look for T and find the opposite of that angle which would be 7 and the adjacent would be the number next to it which is 24 so do 7/24 and u get 0.29
Paul needs to invest $10000 at 6% interest and $30000 at 10% interest to make a total of 9% return on his $40000.
<em><u>Explanation</u></em>
Suppose, the amount of money at 6% interest is
As Paul has total $40000 to invest, so the amount of money at 10% interest will be: 
His intent is to earn 9% interest on his $40000 investment. So, the equation will be......

So, Paul needs to invest <u>$10000 at 6% interest</u> and ($40000- $10000) or <u>$30000 at 10% interest </u>to make a total of 9% return on his $40000.
Answer:
$89
Step-by-step explanation:
add all the numbers together
<u>We'll assume the quadratic equation has real coefficients</u>
Answer:
<em>The other solution is x=1-8</em><em>i</em><em>.</em>
Step-by-step explanation:
<u>The Complex Conjugate Root Theorem</u>
if P(x) is a polynomial in x with <em>real coefficients</em>, and a + bi is a root of P(x) with a and b real numbers, then its complex conjugate a − bi is also a root of P(x).
The question does not specify if the quadratic equation has real coefficients, but we will assume that.
Given x=1+8i is one solution of the equation, the complex conjugate root theorem guarantees that the other solution must be x=1-8i.
