Answer: 2
Step-by-step explanation:
For this question we will use the following relations.
100 centimeters=1 meter (or 1 centimeter= 0.01 meter)
10 millimeter=1 centimeter (or 1 mm=0.1 cm)
60 minutes = 1 hour (or 1 min=
hour)
Now, Jackson's speed is 1350 meters per hour. This can be converted to cm per minute as follows:
...Equation 1
Likewise, Jonah's swim speed in cm/min can be calculated as:
...Equation 2
As we can see clearly after comparing Equation 1 and Equation 2, Jonah's swim speed of 7500 cm/min is faster than that of Jackson.
Thus, option B is correct.
Answer:
390 cm squared
Step-by-step explanation:
15 x 20 = 300
1/2 x 15 x 12 = 90
90 + 300 = 390
Answer:
The answer to your question is the letter C
Step-by-step explanation:
Data
When we multiply a scalar by a matrix, we must multiply the scalar by each of the numbers of the matrix and the result of the multiplication stays in the same place.
For this problem:
3 | -2 0 | = | (-2 x 3) (0 x 3) |
| 4 -7 | | (4 x 3) (-7 x 3) |
= | -6 0 |
| 12 -21 |
3. 6/8/10 is twice the common Pythagorean Triple 3/4/5.
Answer: A. 10
4. 3/4/5 is a Pythagorean Triple because they're three natural numbers that satisfy a²+b²=c^2, here 3²+4²=5².
Answer: C
Non-zero whole numbers are called <em>natural numbers.</em>
