Answer:
1. 1.96 g/L
2. 1 g/cm³
Step-by-step explanation:
Density is found by dividing mass by volume: d = m/v.
1.
We know that the mass is 0.196 grams, while the volume is 100 mL.
Converting the volume to liters, we get:
100 mL = 0.1 L
Then, applying our density formula:
d = m/v
d = 0.196 g / 0.1 L = 1.96 g/L
2.
Here, we know that the mass is 27 grams. However, we don't know the volume, which we need to find.
The block of wood is 3 cm on all sides, which means it's a cube. The volume of a cube is denoted by V = s³, where s is the side length. Here, s = 3, so V = s³ = 3³ = 27 cm³.
Applying our density formula gives:
d = m/v
d = 27 g / 27 cm³ = 1 g/cm³

Answer:
x+27 ≤ 40
You cannot buy more than 13
If you buy 15 they will not fit
Step-by-step explanation:
To determine the number of CD's that will still fit
The number of CD's must be less than or equal to 40
You already have 27.
Let x be the number you are going to buy
x+27 ≤ 40
Subtract 27 from each side
x+27-27 ≤ 40
x ≤ 13
You cannot buy more than 13
If you buy 15 they will not fit
It is 65° because angle 6 and angle 4 are alternate interior angles so they are the same
