Answer:34.7 55.3

Step-by-step explanation: Complementery angles mean that they add to 90 degrees so we can repersent that in the equation x=(90-x)-20.6 first lets add like terms x=69.4-x (nice) now lets add x to each side 2x=69.4 now to get rid of the two lets divide by 2 on each side x=34.7. The angle that is 20.6 degrees less than its complementary angle has been found, to find the other angle add 20.6 degrees to the one we just found.

Ruiz invests $55 at a simple interest rate of 4%. How much interest will he earn after 5 years?
Yanka [14]
To answer this item, I assume that it is compounded yearly such that the amount of interest (I) from the given present worth (P), interest rate (i) and the number of years (n) is calculated through the equation,
                                     I = P x (1 + i)^n - P
Substituting,
                                     I = ($55) x (1 + 0.04)^5 - $55
                                        I = 11.91
The answer is nearest to the first choice, $11.

Find two positive numbers so that twice their sum equals their product and one number is 10 times the other number. Enter the sm
Softa [21]

Answer:

Step-by-step explanation:

We'll call the 2 numbers x and y. Starting with the last part of that first sentence "one number is 10 times the other number" can be written, in algebraic form:

y = 10x

Now on to the first statement about the numbers: "twice their sum" is 2(x + y) and "equals their product" is = xy. Putting that all together:

2(x + y) = xy and we know that y = 10x so

2(x + 10x) = x(10x) and

2(11x)=10x^2 and

10x^2-22x=0 and

x(10x - 22) = 0 so

x = 0 or 10x - 22 = 0 which makes

x equal to \frac{22}{10}=2.2

So x = 2.2 and y = 22.
