Suppose you have a tablet with a capacity of 35 gigabytes. for a plain text book, one byte typically corresponds to one charact

steposvetlana [31]

The first thing we must keep in mind is the following unit conversion:
$1 gigabytes = 1 * 10 ^ 9 bytes
$
We have then that for 35 gigabytes:
$35 * (1 * 10 ^ 9) = 35 * 10 ^ 9 bytes
$

Part A:
For this case we make the following rule of three:
2000 bytes --------------> 1 page
35*10^9 bytes ----------> x
From here, we clear x:
$x = (35 * 10 ^ 9) / (2000)

x = 17500000 pages$

Part B:
Then, the number of 500-page books is:
$n = (17500000) / (500)

n = 35000

4/9 of the people at a party drink Mountain Dew, the rest drink Sprite. If 52 people drink Mountain Dew, how many people drink S

Nuetrik [128]

Answer:

117

Step-by-step explanation:

4 : 9 = 52 : 117

Since

4 : 9 = 52 : X

Then we know

9/4 = X/52

Multiplying both sides by 52 cancels on the right

52 × (9/4) = (X/52) × 52

52 × (9/4) = X

Then solving for X

X = 52 × (9/4)

X = 117

Therefore

4 : 9 = 52 : 117

john, a meteorologist recorded the tempetures from monday to friday and the temeturesof five days was 40f. the tempeture red=cor

LUCKY_DIMON [66]

Answer:

Step-by-step explanation:

To find the average, you need to add all the numbers in the set and divide that value by the total amount of numbers there are,

We already know that the average of the set of temperatures is 40,

Since there are 5 different days with temperatures, multiply 40 by 5,

40 × 5

= 200

200 is what all the temperatures should equal once they are added up,

Now add 40, 39, 44, and 40 together,

40 + 39 + 44 + 40

= 163

Now subtract 163 from 200,

200 - 163

= 37

Therefore the temperature that was recorded on the fifth day was 37f.
