Answer:
Step-by-step explanation:
Let the speed of current be x
<u>Speed of the boat in same direction as current is</u>
<u>Speed against the current is</u>
<u>Based on the given we get the equation for time</u>
<u>Solving for x</u>
- 6(10 - x) = 4(10 + x)
- 60 - 6x = 40 + 4x
- 6x + 4x = 60 - 40
- 10x = 20
- x = 2
The answer is 2 mph
Answer:
0.07 Locate and underline the hundredths place (6) then look at the digit to the right (9):
0.069
Step 2: In this case, the digit to the right (9) is 5 or above. So, we add 1 to the hundredths place (6). The digit(s) after the (6) are replaced by zeros (or dropped)
Answer:
x=120
Step-by-step explanation:
This shape has 6 sides. It is a 720 degree shape.
to find an angle just get 720 divided by 6
720/6=
120
Answer:
C. This is true. If there is more than one entry equal to 0, all powers of P will contain 0 entries. Hence, there is no power k for which Upper P Superscript k contains all positive entries. That is, P will not satisfy the definition of a regular matrix if it has more than one 0
Step-by-step explanation:
The correct option is C as it represents that by considering a matrix P that involves more than one zero and at the same time the powers for all P has received minimum one zero or it included at least one zero
Therefore the statement C verified and hence it is to be considered to be valid
Hence, all the other statements are incorrect
