Answer:
14 pages
Step-by-step explanation:
You can pick any number of pages to check ; I started with 13. Jerry is still at a better time with 108 s.
t=30+6(13)
t-108s
Once you get to 15 , it changes . They both have the same time at 120 s. SO , the maximum number of pages where Jerry still has a shorter time is 14.
Let's call :
x=the number of downloaded standard version
y= the number of downloaded high-quality version
We have : -the high-quality version was downloaded three times as often as the
standard version => 3x=y
-standard version is 2.8 megabytes .the high-quality version is 4.6
MB.The total size downloaded for the two versions was 4482 MB
=> 2.8x+4.6y=4482
Solve for x,y
x=270 , y=810
Answer:
4=x
Step-by-step explanation:
y=-x+4
y=2x-8
-x+4=2x-8
+x +x
4=3x-8
+8 +8
12=3x
/3 /3
4=x
Answer:
Length of perpendicular by pythagoras theorem :
P² = H² - B²
P² = 3² - 1²
P² = 9 - 1
P² = 8
P = 2√2
