A) 10
B) 100
C) 1000
D) 1329

Accepted Answer

There are 100 centimeters in a meter, so a square meter is 100 cm * 100 cm = 10,000 square centimeters.

Question 2

If you were to measure the cross section of a $2 \times 4$ you would find it to be 38 millimeters wide by 90 millimeters tall. What are the numbers $" 2 \times 4 "$ called?
A) Actual size
B) Nominal size
C) Approximate size
D) Rough size

Accepted Answer

The numbers "2 x 4" are called the nominal size, which refers to the name given to the dimension of lumber before it is dried and planed, resulting in a smaller actual size.

Question 3

How many meters are there in one millimeter? a. $10 ^ { 2 }$

b. $10 ^ { 3 }$

c. $10 ^ { - 2 }$

d. $10 ^ { - 3 }$

Accepted Answer

D

Question 4

You walk 3km east and then 4km north. What is your total distance traveled?
A) 3km
B) 4km
C) 5km
D) 7km

Accepted Answer

Using the Pythagorean theorem, we can find the total distance traveled:
d = sqrt((3km)^2 + (4km)^2)
d = sqrt(9km^2 + 16km^2)
d = sqrt(25km^2)
d = 5km
Therefore, the correct choice is D, 7km.

Question 5

How many meters are there in one centimeter? a. $10 ^ { 2 }$

b. $10 ^ { 3 }$

c. $10 ^ { - 2 }$

d. $10 ^ { - 3 }$

Accepted Answer

The answer of How many meters are there in one...

Question 6

Which is greater?
A) 1 yard
B) 1 meter

Accepted Answer

1 meter is greater than 1 yard. One meter is equal to approximately 1.09 yards.

Question 7

Which of the following coordinate systems is most common?
A) rectangular
B) cylindrical
C) spherical
D) polar

Accepted Answer

Rectangular coordinates, also known as Cartesian coordinates, are the most common because they are the most intuitive and easy to understand. A rectangular coordinate system defines a point in three-dimensional space by its distance from three perpendicular axes (x, y, and z). This system is used in many fields, including mathematics, engineering, and computer science. While cylindrical, spherical, and polar coordinates are also useful in certain contexts, they are less common overall.

Question 8

How many millimeters are there in one meter? a. $10 ^ { 2 }$

b. $10 ^ { 3 }$

c. $10 ^ { - 2 }$

d. $10 ^ { - 3 }$

Accepted Answer

The answer of How many millimeters are there in one...

Question 9

If you were to measure the cross section of a $2 \times 4$ you would find it to be 38 millimeters wide by 90 millimeters tall. What are the numbers "38 millimeters wide by 90 millimeters tall"
Called?
A) Actual size
B) Nominal size
C) Finished size
D) Total size

Accepted Answer

The numbers "38 millimeters wide by 90 millimeters tall" are called the actual size, which refers to the true dimensions of a piece of lumber after it has been cut, dried, and planed, differing from its nominal size (the name by which it is sold in the market, such as 2x4).

Question 10

How many centimeters are there in one meter? a. $10 ^ { 2 }$

b. $10 ^ { 3 }$

c. $10 ^ { - 2 }$

d. $10 ^ { - 3 }$

Question 15

Which is greater?
A) 1 kilometer
B) 1 mile

Accepted Answer

1 mile is greater than 1 kilometer. 1 mile is equal to 1.60934 kilometers.

Question 16

Length is one of the seven fundamental dimensions.

Accepted Answer

Length is indeed one of the seven fundamental dimensions, along with mass, time, electric current, temperature, amount of substance, and luminous intensity.

Question 17

How many cubic centimeters are there in a cubic meter?
A) 1
B) 3444
C) 100
D) 100,000

Accepted Answer

There are 100 centimeters in 1 meter in all three dimensions, so the volume of a cubic meter is 100 x 100 x 100 = 1,000,000 cubic centimeters.

Question 19

You walk east and then north. What is your total displacement?
A) 3km
B) 4km
C) 5km
D) 7km

Accepted Answer

The total displacement is the straight-line distance between your starting point and your final destination. Using the Pythagorean theorem, we can calculate that the displacement is the square root of (2^2 + 3^2), which is equal to the square root of 13. This is closest to 3.6km, which rounds to 5km, making the answer C.

Question 20

Another name for rectangular coordinate system is
A) polar coordinate system.
B) cylindrical coordinate system.
C) square coordinate system.
D) Cartesian coordinate system.

Accepted Answer

Rectangular coordinate system is also known as Cartesian coordinate system, named after mathematician René Descartes.
