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.

A Standard number is<br> tossed find each<br> Probability.<br> P (4 or less than 6)
Klio2033 [76]

the probability of rolling 4 or a number less than 6 is P = 5/6

<h3 /><h3>How to find the probability?</h3>

The standard number cube has the outcomes {1, 2, 3, 4, 5, 6}

We want to find the probability of rolling 4 or a number less than 6. (4 is a number less than 6).

The outcomes that meet that condition are:

{1, 2, 3, 4, 5}

So 5 out of 6 outcomes meet the condition, then the probability is:

P(4 or less than 6) = 5/6

Answer:

it 5.5⋅10−^8m

Step-by-step explanation:

Unless I'm missing something important here, you can find the difference between the two wavelengths by subtracting one from the other. Since you're interested in finding how much longer the wavelength associated with the orange light is, subtract the wavelength of the green light from the wavelength of the orange light. You know that the two measured wavelengths are 6.15 ⋅ 10 − 7 m → orange light 5.6 ⋅ 10 − 7 m → green light Therefore, the difference between the two wavelengths will be Δ wavelength = 6.15 ⋅ 10 − 7 m − 5.6 ⋅ 10 − 7 m = 5.5 ⋅ 10 − 8 m

1. 3+2+1+2+3+1=12
2. 5+6+6+7+6+6=36
3. 2+4+3+3+2+4=18

Then add all those numbers up and divide them by 18.
12+36+18=66/18=3.6 you can round it up to c.4.
