Answer:

18600 square inches

Step-by-step explanation:

To find the number of square inches of cardboard will the factory need to build 50 boxes, we find the total surface area of the cereal box which is A = 2(lw + lh + hw) where l = length of box = 10 inches, w = width of box = 3 inches and h = height of box = 12 inches.

Substituting the values of the dimensions into A, we have

A = 2(lw + lh + hw)

= 2(10 × 3 + 10 × 12 + 12 × 3) in²

= 2(30 + 120 + 36) in²

= 2(186) in²

= 372 in²

So, the area of one box is 372 in². The area of 50 boxes is thus, area of one box × 50 = 372 in² × 50 = 18600 in²

So we require 18600 square inches of cardboard to build 50 boxes.

The owner of an office building is expanding the length and width of a parking lot by the same amount. The lot currently measure
Gnoma [55]

The best and most correct answer among the choices provided by your question is the second choice or letter B "20".

The current area is 120(80)=9600 and he want to expand it by 4400 so that the new area will be 9600+4400=14000 

14000=(120+x)(80+x) 

14000=9600+200x+x^2 

x^2+200x-4400=0 

x^2-20x+220x-4400=0 

x(x-20)+220(x-20)=0 

(x+220)(x-20)=0, since x is an increase it must be greater than zero so 

x=20ft 

(120+20)(80+20)=14000ft^2


I hope my answer has come to your help. Thank you for posting your question here in Brainly.

If I could get some help it would be very much appreciated
raketka [301]

Answer:

Step-by-step explanation:

A circle is 360 degrees. What we are asked in words is, "How many degrees is 40% of 360?" Let x be "how many degrees"; the word "is" means =; 40% as a decimal is .4; the word of in this context means to multiply; and 360 is just 360. Putting all that together into an equation we can solve for x:

x = .4(360) so

x = 144

Adventure movies covers 144 degrees of that circle.
