I believe the answer is 30.51, but you should verify by dividing.
To tackle this, we can utilize ratios. For instance, 4 1/2 kg of olive oil costs $27. Therefore, the price for 1 kg of olive oil can be represented as follows: x = (27 * 1) / 4.5 which simplifies to x = 27/4.5. This calculation results in a cost of $6 per kilogram. Hope this is of assistance!
To find the volume of an aluminum cylinder with a mass of 12.4 g and a length of 2.00 cm:
V = π r² L
Density of aluminum is 2.7 g / cm³
Therefore, V = 12.4 g: 2.7 g/cm³ ≈ 5 cm³
5 = 3.14 · r² · 2
r² = 5: 6.28
r² = 0.796
r = √0.796
Thus, the radius of the aluminum cylinder is 0.9 cm.
Answer:
The radius of an aluminum cylinder is 0.9 cm.
For lines that are perpendicular, their slopes are negative reciprocals. For instance, if line a’s slope is 2/3, then line b must have a slope of -3/2.
Answer:
The scale factor is measured to be 2.5.
Step-by-step explanation:
The triangles are depicted below.
In triangle ΔABC,
the side lengths are AB = 2 units, BC = 2 units
In triangle ΔA'B'C',
the side lengths are A'B' = 5 units, B'C' = 5 units.
The formula for the scale factor in a dilation is given by:
Scale factor = 
Thus, the scale factor is 2.5.
