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:
"no additional days of food need to be ordered."
Step-by-step explanation:
Suppose initial quantity of food is x units
Assuming each student eats 1 unit of food per day,
x = 30 * 100 = 3000 units of food
In 2 days, food eaten:
100 * 1 * 2 = 200 units
So food left after 2 days is 3000 - 200 = 2800 units
Now, there are 140 students. They stay 2 weeks (14 days) - 2 = 12 more days
So food eaten in 12 days:
140 * 1 * 12 = 1680 units
<u>THus, after total 14 days gone, the amount of food left is:</u>
2800 - 1680 = 1120 units
Half students left, so there are 70 students left for the last 16 days. How much food would they need?
70 * 1 * 16 = 1120 units
And there are exactly 1120 units left. So, no additional days of food need to be ordered.

Answer:
- left 3 units
- up 4 units
- shape: lower left image
Step-by-step explanation:
For a parent function f(x), the transformations ...
g(x) = a×f(x -h) +k
cause ...
- vertical expansion by 'a', reflection over x-axis if negative
- right shift by 'h'
- up shift by 'k'
Here, we have parent function f(x) = 1/x with a=-1, h=-3, k=4. Then the transformations are ...
horizontal shift left 3 units
vertical shift up 4 units
reflection over x-axis, so curves are above-left and below-right of the reference point (Note that the reflection is done <em>before</em> the translation.)
