Answer:

$6\frac{4}{7}$

Step-by-step explanation:

Hello,

I am going to start with to change to a improper fraction:

1. I will convert 6 and 9/10 into a improper fraction:

$69/10$

2. Now that I have converted the mixed fraction into a improper I can multiply the numerator and the denominator.

$69 * 20 / 21 * 10 = 1380/210$

3. Now I can simplify this value and convert it into a mixed fraction

$46/7$

After further simplifying I can convert this into an mixed number

$6\frac{4}{7}$

A bank account has a beginning of 560.00. After 6 months, the balance in the account has increased to 572.60. What interest rate

MaRussiya [10]

This is tricky because we are given the interest rate for the year but the problem is figureing the interest for 6 months or 1/2 year. We will have to double the difference before solving for the yearly interest.

572.60 - 560.00 = 12.60 interest added for 6 months x 2 = 25.20 for 12 months

(This problem assumes the interest will stay the same the next 6 months)

We need to find what percent 25.20 is to our original balance.

25.20/560 = x / 100

2520 = 560x

x = 4.5 percent interest

Check .045 x 560.00 = 25.20 interest in one year (or 12.60 in 6 months)

Explain why the equation 5z + 2 = 5z has no solution.

suter [353]

$5z + 2 = 5z \\ 5z - 5z = - 2 \\ 0 = - 2$

Answer : This is because when 5z minus 5z, it is nullified, with no way to determine the value of z. 5z - 5z = 0
That is why there is no solution for this equation.

Hope this helps. - M

Help with 9, 10, and 11 please you will get 50 points!

Lubov Fominskaja [6]

Step-by-step explanation:

<FGL is acute
<HGF is acute
<KGH is acute
<KGF is obtuse
<KGL is obtuse
<HGL is right

value of complement is 90 and obtuse angle refers to angles that is above 90. complement can be said right angle but not obtuse.

The sum of two acute angles sometimes results in an obtuse angle.
Two obtuse angles are never supplementary.
The sum of two right angles always results in a straight angle.
