Answer:
100g : 60g : 80g
Step-by-step explanation:
5+3+4 =12 total parts
(5/12 of 240)
5/12 x 240 = 100g
3/12 x 240 = 60g
4/12 x 240 = 80g
Check:
100g + 60g + 80g = 240g

First, determine the z-score of 675.
z = (675 - 500) / 100 = 1.75
The z-score of 500 is,
z = 0.
Subtracting the z-scores will give us 1.75. This is equal to 0.9599.
= 0.9599 - 0.5 = 0.4599
Multiplying this to the given number of light bulbs,
n = 0.4599 x 5000 = 2299.5
Therefore, there is approximately 2300 light bulbs expected to last between 500 to 675 hours.
Hey there!
I think that it safe to say that this room is a rectangular prism. Therefore, the top and bottom (floor and ceiling) have the same area. We see that our floor dimensions are 12 cm long and 7 cm wide. This also applies to the ceiling. Let’s take our two sides and multiply then to find our area.
12(7)=84
Therefore, the area is 84 square centimeters.
I hope that this helps!
Answer:
They went up 16 levels.
Step-by-step explanation:
You can find that by finding the distance from -2 to 14.
To find the distance from two numbers, 
and 
, we can substitute both in the formula 
, where d is the distance between them.
Answer:
Infinitely
Step-by-step explanation:
Hi,
Both sides of the equation are equal to each other, this means they're the exact same line and overlap. This is infinitely many solutions.
