8 0

Answer:

2.3lego

Step-by-step explanation:

We can walk through this problem using the cross multiplication method

First 3 1/2 lego is same as 3.5lego

Hence If

Johnny builds 3.5lego in 60min

He can build xlego in 40min

Crosss multiplying we have

Xlego *60= 3.5*40

Xlego= 140/60= 2.3lego

A pile of earth removed from an excavation is a cone measuring 6ft high and 30ft across its base. How many trips will it take to
nignag [31]

Answer: 14

Step-by-step explanation:

Given

Excavation cone measures

height h=6\ ft

Diameter d=30\ ft

Truck can dump 125\ ft^3 at a time

The volume of a cone is

V=\dfrac{1}{3}\pi r^2h

Putting values

\Rightarrow V=\dfrac{1}{3}\times \pi\times 15^2\times 6\\\Rightarrow V=1413.9\approx 1414\ ft^3

No of trips(N) required to accumulate this much volume is given by

\Rightarrow N=\dfrac{1414}{125}=13.3\approx 14

Therefore, 14 trips are necessary to accumulate a cone of volume 1414\ ft^3
