3a. Jackson's gross pay for 40 hours is
  (40 h)×($12.20/h) = $488.00

3b. An equation for Jackson's pay could be
  372.10 = h×12.20
This can be solved for h by dividing by 12.20
  372.10/12.20 = h = 30.5
Jackson worked 30.5 hours last week.

3c. The total of hours shown is
  (8) + (7 1/4) + (8 1/2) = (8 +7 +8) +(0.25 +0.50) = 23.75
The number of hours missing is the difference between this number and the hours found in part (b).
  30.50 - 23.75 = 6.75
There are 6 3/4 hours missing from Jackson's time sheet for last week. This is less than a full day's work, so seems reasonable.


_____
Of course, you know the decimal - fraction conversions:
  1/4 = 0.25
  1/2 = 0.50
  3/4 = 0.75

What is the ratio for consonants to vowels,Vowels to total letters,and all letters to consonants
Studentka2010 [4]

Answers:

  • Ratio of consonants to vowels = 21:5
  • Ratio of vowels to total letters = 5:26
  • Ratio of all letters to consonants = 26:21

================================================

Explanation:

vowels = {a, e, i, o, u}

consonants = anything but a vowel (eg: the letter R)

There are 26 letters in the English alphabet. Five of which are vowels, so there are 26-5 = 21 consonants.

The ratio of consonants to vowels is 21:5

The <u>order is important</u> because the number of consonants must be listed first, simply because "consonants" is mentioned first in the phrasing "ratio of consonants to vowels". In other words, writing 5:21 would mean the ratio of vowels to consonants.

The ratio 21:5 cannot be reduced further since 21 and 5 have no factors in common (other than 1).

------------------------------

The other ratios will follow a similar idea as mentioned in the previous section.

To get the ratio of vowels to total letters, we list the number of vowels first (5) follow by the number of letters (26). A colon separates the two numbers to form the ratio 5:26

This ratio cannot be reduced further.

-------------------------------

Like in the previous sections, we'll glue together two numbers to form a ratio. In this case, we have 26 letters glued with 21 consonants to form the ratio 26:21 and this represents the ratio of total letters to consonants.

This ratio cannot be reduced further.

2.) Use the Slope Intercept Form of a line to find the equation of the line from point C to point D.
mezya [45]

First we need slope

  • C=(0,0)
  • D(7,12)

\\ \sf\longmapsto m=\dfrac{12-0}{7-0}

\\ \sf\longmapsto m=\dfrac{12}{7}

Put D co-ordinates on y=mx+b

\\ \sf\longmapsto 12=\dfrac{12}{7}(7)+b

\\ \sf\longmapsto 12=12+b

\\ \sf\longmapsto b=12-12

\\ \sf\longmapsto b=0

Now

slope intercept form.

\\ \sf\longmapsto y=\dfrac{12}{7}x

  • As b=0

Mia has n pairs of earrings. She receives 3 more pairs of earrings. Which expression represents the number of earrings Mia has n
kvv77 [185]
I believe the correct answer from the choices listed above is option D. The expression that would represent the number of earrings Mia has now would be n+3. It should be the sum of n earrings she originally had and the additional 3 earrings. Hope this answers the question.
