Answer:

There are 60 activity booklets in the media lab.

Step-by-step explanation:

- 30/2 = 15

Why divide those numbers?

For every 2 computers in a lab with 30 computers means you have to divide

- 15x4 = 60

Why multiply those numbers?

4 activity booklets for every 2 computers in a lab of 30 computers, so multiply

I hope this helps.

Let point L be between M and N on MN. Given that MN=31, ML= h-15 and LN = 2h-8. Find LN

san4es73 [151]

Since point L is merely found on the line MN, ML and LN are considered to be line segments. So adding both line segments should add up to line MN's total length which is 31 units. We can use the given relations to create a mathematical equation as follows:

Given: MN = 31; ML = h - 15; LN = 2h - 8

MN = ML + LN

Substituting the given values:
31 = h - 15 + 2h - 8
31 = 3h - 23

It is necessary to solve for the value of h. To do this, we must isolate h and solve for it:

Adding 23 to both sides of the equation:
31 + 23 = 3h - 23 + 23
54 = 3h
h = 18

Substituting the value of h to the equation of LN we get the following:
LN = 2(18) - 8
LN = 36 - 8
LN = 28

Therefore the value of LN is 28.

In 1968 it cost $54 000 for a 30-second commercial during the super bowl. In 1973, the cost for a 30-second commercial was $88,0

Answer:

63 %

Step-by-step explanation:

Percentage change in value value for any number is given by

percentage change = (new value - old value) /old value * 100

we can also write it as

percentage change = (change in value ) /old value * 100

________________________________________

cost of commercial in 1968 = $54000

cost of commercial in 1973 = $88000

change in cost of commercial = cost of commercial in 1973 - cost of commercial in 1973 = $(88000-54000) = $34000

thus,

percentage change in cost of commercial

= change in cost of commercial/cost of commercial in 1968 * 100

= 34000/54000*100 = 62.96 %

Thus, percentage change in cost of commercial is 62.96 %

we have to round it to nearest whole number

rounded value of 62.96 is 63

in that case

percentage change in cost of commercial is 63 %
