Answer: Iron, a solid at room temperature, becomes a liquid at 2800 degrees Fahrenheit (really, REALLY hot) and a gas at 5182 degrees Fahrenheit (about half the temperature of the sun). When things are hot, the molecules and atoms move around more and faster, and when they are cold they are slower.
Step-by-step explanation:
A)
d =240/a
B) 2 loads of gravel
Step-by-step explanation:
Step 1:
Given one load of gravel is 240 ft2.
We have depth = 240/area
Hence the inverse variation model is d =240/a
Step 2 :
The length and breadth of the playground is 40 ft and 24 ft
The depth of the playground is 6 in = 6/12 ft
Hence the volume of the given playground is 40 * 24 * 6/12 = 480 cu ft.
There is 240 ft2 of gravel in one load
So we need 480 cu ft of gravel = 480/240 = 2 loads of gravel.
Answer: c) 0.6
<u>Step-by-step explanation:</u>
0 is not a success so that value is not included.
1 and 2 are successes so those values are added:
0.48 + 0.16 = 0.64
Rounded to the nearest tenth is: 0.6
Answer:
see explanation
Step-by-step explanation:
Express the ratios in fractional form, that is
=
( cross- multiply )
y + 3 = k(y + 5) ← distribute
y + 3 = ky + 5k ( subtract ky from both sides )
y - ky + 3 = 5k ( subtract 3 from both sides )
y - ky = 5k - 3 ← factor out y from each term on the left side
y(1 - k) = 5k - 3 ← divide both sides by (1 - k)
y =
