So the first thing you do is you divide 1024 by 256. you will come out with the answer of 4. it takes 4 seconds to download 1 megabyte. but, it takes 4 megabytes, so you need to multiply 4 by 4. you will get 16. it takes 16 seconds to download 1 song.
to figure out how many songs Lindy can download in 2 hours, you multiply 60 by 60. you will get an answer of 3600. there are 3,600 seconds in an hour. now to find out how many are in 2 hours you multiply 3,600 by 2. you will get a sum of 7,200
now to figure out how many songs Lindy can download in 2 hours, you divide 7,200 by 16. you will come out with a quotient of 450.
Lindy can download a total of 450 songs in the space of 2 hours.
Answer:
y=13x – 2
Step-by-step explanation:
Using the slope intercept form
y= mx + b
Where, m= 13 & b= –2
y= 13x – 2

Answer:
The equation is whose solution is
Step-by-step explanation:
Let us call the number of minutes the phone is used over 200 minutes, then we have
<em>(this says monthly bill of $40 plus the cost of phone usage over 200 minutes must equal $58 )</em>
This equation can be used to solve for u as follows:
The number of sociology books is 59 and the number of biology books is 177.
Step-by-step explanation:
Given,
The number of biology textbooks sold was three times the number of sociology textbooks.
Total number of books = 236
To find the number of each types of books.
Let,
The number of sociology books = x
The number of biology books = 3x
According to the problem,
3x+x = 236
or, 4x = 236
or, x =
or, x = 59
Hence,
The number of sociology books = 59
The number of biology books =3×59 = 177
