Mathematics
1 answer:
Mandarinka [93]3 years ago
4 0

Answer:

3x +89 + 8x + 58 =180 (they are supplementary angles, so added together they are equal to 180)

11x + 147= 180 (combine like terms on the left side of the = sign)

11x= 33 (subtract 147 from both sides and then divide by 11 to isolate x)

x= 3  (this is x)

3x +89 (this is the measure of angle MON, plug in x and solve)

3(3)+89

9+89

98 degrees (this is your answer)

Bad Investment After Mrs. Fisher lost 9% of her investment, she had $22,750. What was Mrs. Fisher's original investment?​
stira [4]

Answer:

$2500

Step-by-step explanation:

Given that,

The lost percentage = 9%

Amount she had = $22,750

We need to find Mrs. Fisher's original investment.

As she had lost 9%, it means she will remain with 91% of her investment. Let the original investment is x.

So,

91\%\ of \ x=22,750\\\\\dfrac{91}{100}x=22,750\\\\x=\dfrac{22,750\times 100}{91}\\\\x=\$25000

So, her original investment is equal to $25000.

10 free points if you know answer to the question. always loooking to make peoples days better!
ira [324]

What you need to know in order to answer this:

       In math, the symbol " ! " is used to indicate "factorial".
       "Factorial" means the product of the integers from 1
       up to the number.

Examples:

       
2 !  =  "two factorial"  =  1 * 2  =  2

        4 !  =  "four factorial"  =  1 * 2 * 3 * 4  =  24

For this question:

  10 !  =  "ten factorial"  =  1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 * 9 * 10

                                       =  3,628,800 .

If you look at your calculator very closely, I'll bet you
there's a key on it marked " x ! " .
Enter a whole number into the calculator, and that key
gives you the factorial of the number.

And by the way, the points aren't 'free'.  I had to
give you some information in order to earn them.
