Answer:
Manuel would be correct, the volumes would be equal.
Step-by-step explanation:
The formulae for finding the volume of pyramids and cones both include dividing three (multiplying by
).
Square pyramid formula:
×B×h where B is the area of the base. By plugging in numbers we have that B=314.159 and h=5. 314.159×
×5=523.5983.
Cone formula: The basic formula is the same:
×B×h, but the area of the base is found using the circle formula of π×r². For the cone we have B=314.159 and h=5. 314.159×
×5=523.5983.
Since both of these formulas came up with the same answer, we can conclude that Cone W has the same volume as Pyramid X, which is Manuel's answer.

Step-by-step explanation:
-18=x+10
move +10 to the other side
sign changes from +10 to -10
-18-10=x+10-10
-18-10=x
Answer: x=-28
Answer:
She would save £5
Step-by-step explanation:
→ First work out the cost of items for one student. Work out cost of the photocopying
40 × £0.02 = £0.80
→ Add the cost of the one folder
£0.80 + £0.70 = £1.50
⇒ Now we know £1.50 is the amount of money it costs for one student, we multiply that by 120 because there are 120 pupils
£1.50 × 120 = £180
→ £180 is the total cost and now we minus that from the online price of £175
£180 - £175 = £5
