Answer:

40 students gave their speeches.

Step-by-step explanation:

Anytime in math that it says the word "of" it means multiplication. So, in this situation, we are multiplying:

(5/8) x 64.

But, when you are multiplying a fraction by a number, you are actually dividing instead of multiplying. Think of it this way: the question is asking you 5/8 <em>of</em> 64, meaning you must find how many is 5/8 <em>of</em> the amount of students that gave their speeches is. Also, that slash between the 5 and the 8 in the fraction is actually a division symbol. So, by placing 5/8 into 64, we get:

(5/8) x 64 = 40.

I'm quite sure why it asked for "simplest form" when the answer is not a decimal or fraction, but this is the answer to the problem that you have posted.

I hope that this helps.

The nominal rate on Sarah’s loan is 7. 250%. If the interest is compounded monthly, what rate of interest is Sarah actually pa
ella [17]

The correct statement is that Sarah is paying interest compounded monthly at the rate of 7.496%.. So, the correct option from the above statement is B.  

Compound interest can be calculated by the way of applying the values to the formula given in the information.  

<h3>Compound Interest</h3><h3 />
  • Compound interest is best defined with the terms as interest given on accrued interest or the accumulated interest in addition to the interest on the principalprincipal amount.

  • The formula to calculate Compounded interest is as below,

  • \rm Compounded\ Interest = 10000(1+ \dfrac {0.0725}{12})^1^2\\\\\\\rm Compounded\ Interest =10000(1+0.006)^1^2\\\\\\\rm Compounded\ Interest =10749.58\\

  • The interest to be paid is calculated as $749.58 assuming that the principal was $10000 and the time for such loan was 1 year in the absence of information.

 

  •  Calculating further, we can find that the effective rate of interest on such a loan is at the rate of 7.496%, which is rounded off to the nearest three decimal places.

Hence, the correct option is B that the actual interest paid by Sarah at the rate of 7.250% for the period of 1 year will be effectively 7.496%

9. What statements are NOT true about the<br> solution of the system?
Crazy boy [7]

Answer:

A, B, C, and E

Step-by-step explanation:

y = 4x - 20

8x - 2y = - 20 (divide everything by 2)

4x - y = -10

-y = -4x - 10

y = 4x - 10

4x - 10 = 4x - 20

0 \neq -10
