Question

Peggy the Pig built a house of sticks. The stick-house can withstand wind speeds up to 47km per hour. Choose the best approximation of the highest wind speed that Peggy's stick-house can withstand. Choose 1 answer. A. 5•10^1 km per hour. B. 5•10^2 km per hour.

Answer 1

A

Explanation:

5*10^1=5*10=50

5*10^2=5*100=500

Answer 2

The correct option for the best approximation of the highest wind speed that Peggy's stick-house can withstand is A) 5•10^1 km per hour.

Explanation:

Consider the provided information.

Peggy the Pig built a house of sticks. The stick-house can withstand wind speeds up to 47km per hour.

Round up the number 47 to the nearest tens.

The round up of the number is 50,

Now consider the provided options.

A.
`5\cdot 10^1` km per hour.

This can written as: 5·10=50 km per hour.

Therefore, it is the correct option.

B.
`5\cdot 10^2` km per hour.

This can written as: 5·10·10=500 km per hour.

Therefore, it is not the correct option.

The correct option for the best approximation of the highest wind speed that Peggy's stick-house can withstand is A) 5•10^1 km per hour.
