horrorfan [7]

Answer:The number of words that she would still have to type to finish her essay is 1000

Step-by-step explanation:

Karen is typing a 4,000 word essay. She can type at about 30 words per minute. This means that if her rate remains constant, the total number of minutes that it will take her to finish would be

4000/30 = 133.33 minutes.

If she types for 45 minutes on Monday, it means that the total number of words that she typed on Monday would be

45 × 30 = 1350 words

If she types for 55 minutes on Tuesday, it means that the total number of words that she typed on Tuesday would be

55 × 30 = 1650 words

Total number of words typed on Monday and Tuesday would be

1350 + 1650 = 3000 words

The number of words that she would still have to type to finish her essay would be

4000 - 3000 = 1000 words

Calculate the value of each expression:<br> (-8)•(-2/3)<br> SHOW YOUR WORK:
inna [77]

Answer: \frac{16}{3}

Step-by-step explanation:

For this exercise it is important to remember  the multiplication of signs:

(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-

In this case, given the following expression:

(-8)(-\frac{2}{3})

You can idenfity that both factors are negative. Then, the product (The result of the multiplication) will be positive.

Then, in order to get the product, you need to multiply the numerator of the fraction by -8. So, you get:

 \frac{(-2)(-8)}{3}=\frac{16}{3}

You can notice that the numerator and the denominator of the fraction obtained cannot be divided by the same number; therefore, the fraction cannot be simplified.
