Answer:
77 ft²
Step-by-step explanation:
Given that:
Surface Area of larger pyramid = 539 ft²
Scale factor of the smaller pyramid = 1/7
Tbe surface area of the smaller pyramid will be :
Scale factor * surface area
1/7 * 539ft²
= 539 ft² / 7
= 77 ft²
Answer:
2/3 liter
Step-by-step explanation:
3.00 g/cm³ = 3.00 kg/L . . . . . . . 1000 g = 1 kg; 1000 cm³ = 1 L
For a mass of 2.00 kg, you need ...
(2.00 kg)/(3.00 kg/L) = 2/3 L ≈ 0.667 L
1/10 is the probability.
You find this by putting 25/250 and simplifying.
