Answer:
60
Step-by-step explanation:
Sum the parts of the ratio, 5 + 9 + 13 = 27 parts
Divide the amount of concrete by 27 to find the value of one part of the ratio.
324 ÷ 27 = 12 ← value of 1 part of the ratio , thus
5 parts = 5 × 12 = 60 ← cement
9 parts = 9 × 12 = 108 ← sand
13 parts = 13 × 12 = 156 ← gravel
Is it inequality? If so, 5n<65 so n<13
So we're given Y = 3x.
We now can replace Y, for 3x in the equation:
Y = x + 4
3x = x + 4
3x - x = 4
2x = 4
x = 2
Answer: The cone has a larger volume.
Step-by-step explanation:
Volume of a cone = ⅓πr²h
where, radius = 5cm
height = 10cm
Volume = ⅓ × 3.142 × 5² × 10
Volume of cone = 261.83cm³
Volume of square pyramid = A(h/3)
where, A = 10 × 10 = 100cm²
Volume = 100 × (5/3)
Volume of square pyramid = 166.67cm³
Therefore, the cone has a larger volume.
