The school wants to build a new sandbox for the grade R playground the sandbox must be 4m long 3m wide and 0,5m high
Daniel [21]

The new dimensions of the sandbox in centimeter (cm) are:

length = 400 centimeters

Width = 300 centimeters

Height = 50 centimeters

Given:

Length = 4m

Width = 3m

Height = 0.5m

Convert meter to centimeter

1 meter = 100 centimeters

4m = 4 × 100 centimeters

= 400 centimeters

3m = 3 × 100 centimeters

= 300 centimeters

0.5m = 0.5 × 100 centimeters

= 50 centimeters

Therefore, the new dimensions of the sandbox in centimeter (cm) are

length = 400 centimeters

Width = 300 centimeters

Height = 50 centimeters

The average walking speed r of a person living in a population P in thousands is modeled by the function, r(p) = 0.37 ln p + 0.0
Veseljchak [2.6K]

Answer:

The average walking speed is 1.48 feet per second

Step-by-step explanation:

we have

r(p)=0.37ln(p)+0.05

where

r is average walking speed

p is the population  in thousands

In this problem we have

p=48,000/1,000=48 ----> because p in the equation is in thousands

substitute the value of p in the equation

r(p)=0.37ln(48)+0.05

using a calculator

r(p)=1.48\ ft/sec
