Answer 1

Answer: If you have a calculator with graphing capabilities, you can graph the quadratic y=160x-4.9x^2 and the line y=117.6, using the intercepts to find your answer. Doing this you get intercepts of .75 and 31.9
Final answer:
Answer choice A, x<0.75 and x>31.9

If the length of a rectangle is increased by 120 %, and its width is decreased by 20%,what happens to the area of the rectangle?

Answers

Let length of rectangle=x and width be y
.`. area=x*y
now new length=x+12x/10=22x/10
width=y-y/5=4y/5
now .....
new area=new length-new width=22x/10*4y/5
new area=88xy/50

The area of the rectangle will decrease because lets say the length is 2 and the width is 1
originally the area of the rectangle is lxw which is 2x1 is 2. But if we increase the length by 120% which will be 2.4 and increase the width decreased by 20% which is 0.8 then if we multiply them using the formula its 1.92 which decreased

What is the answers ?

Answers

ok so the 2nd and 3rd are obviously wrong
there must be a craxy pattern

hmm
1+4=5 corerct

2+5=7
that is 5 away from 12

3+6=9
that is 12 away from 21

I see it
1+4=5
2+5+5=12
3+6+12=21
so the pattern is takee the result from the last equaton and add to the next

see how it goes, 1,2,3, then jumps to 8
we need to buildto 8
4+7+21=32
5+8+32=45
6+9+45=50
7+10+50=67
8+11+67=86

the result is 86

19 because you have to have to add them

How many years will it take a major hamburger fast food chain to sell 45,000,000 burgers if it sells approximately 12,350 burgers per day? Show work

Answers

$1 day.....12,350 b \n x...........45,000,000b \n\n x=(1*45,000,000)/(12,350) \n\n x=3,643.7 :365 \ (days) \n\n x=9,98 \ days \n\n \boxed{x=9,98\approx 10 \ years}$

If a burger joint sells 12,350 burgers a day, it will take about 10 years to sell 45,000,000 burgers. I say this because 45,000,000 divided by 12,350 is 3643.72. That is how many days it would take to sell 45,000,000 burgers. Now, if you divide 3643.72 by 365 you get 9.98. 9.98 is how many years it would take to sell 45,000,000 burgers.
Hope this helps! :)

Answer: (0,0),(0,4), and (5,0)

Step-by-step explanation:

It is easy to find lengths of horizontal and vertical segments and distances from (0,0) so always place one vertex at the origin and one or more sides on an axis.

Screen measures 30 cm wide n 22 cm high what is the diagonal measure of the screen

Answers

I think you'd use the pythagoran theorem for this (a squared + b squared = c squared). So 30 squared plus 22 squared equals the diagonal measure squared. This is 900 + 484 = c squared. That's 1384. The square root of that is 37.
