Answer:

3  2/3

Step-by-step explanation:

change 5 2/4 into an improper fraction:  5(4)+2 over 4  =  22/4

\frac{2}{3} x \frac{22}{4} = \frac{44}{12}

\frac{44}{12} can be simplified by dividing top and bottom by 4 to get 11/3 or 3 2/3

The event coordinator asks you to determine how many students participated in the track-and-field day. The total number of stude
kakasveta [241]
584 is the total number of students in the school.

5/8 are in seventh grade and 3/8 are in eighth grade.

4/5 of the seventh graders participated in the track meet, so there were (4/5 · 5/8) · 584 students in the seventh grade participating in the track meet.

7/8 of the eighth graders participated, so there were (7/8 · 3/8) · 584 students in the eighth grade participating in the track meet.

So, all together, there were

(4/5 · 5/8) · 584 + (7/8 · 3/8) · 584 students from the school in the track meet.

Let's simplify as you asked:

(4/5 · 5/8) · 584 + (7/8 · 3/8) · 584 = [(4/5 · 5/8) + (7/8 · 3/8)] · 584 (distributive property - factoring)

= [20/40 + 21/64] · 584 (multiply fractions)

= (1/2 + 21/64) 584 (reduce the first fraction to lowest terms)

= (32/64 + 21/64) 584 (getting a common denominator)

= (53/64) 584 (combine/add the two fractions)

= 483.625 (multiply together)

All together, there were: 483.625 students in the meet.

The size of a television is given by the length of its diagonal. What is the size
MA_775_DIABLO [31]

Answer:

it is A. 60 in

Step-by-step explanation:

You need to use the Pythagorean theorem for this. Take the square root of (48^2 + 36^2). This will give you the length of the diagonal.

48^2 + 36^2 = 3600

Remember we need to take the square root of 3600, which is just 60.

The length of the diagonal is 60 inches.
