If you round 62 down to 60 and 22 down to 20, it is easy to multiply them together in your head. Just multiply 6 and 2 and add two 0s.

Knowing that 60 × 20 = 1200, we can tell that the product of 62 × 22 has to be larger, since we rounded down to get 1200.

1042 < 1200, so we know the answer is not reasonable.

The graph below shows the velocity f(t) of a runner during a certain time interval:
Jlenok [28]
For this case, the first thing we must do is take into account the definition of the axes:
 the x axis is time in seconds
 the y axis is velocity in meters per secon
 
 Then, we look for the cut point with the y axis, which is given by:
 (0, 2)
 This means that the initial speed is 2 m / s.
 
 We now look for the cut point with the x axis, which is given by:
 (8, 0)
 This means that the speed is 0 m / s, so the runner stopped when the time is 8 seconds.

 Answer:
 
The initial velocity of the runner was 2 m / s, and the runner stopped after 8 seconds.

Change the following algebraic expressions to the statement in words: i. 3mn +7 ii. xy + (x+y)
kicyunya [14]

Answer:

i) 3*m*n + 7

Then we can write the first term as:

"3 times the product between two numbers"

Where the product of two numbers is m*n

And after that we need to add 7, then the complete sentence is:

"3 times the product between two numbers, increased by 7"

ii) x*y + (x + y)

The first part, x*y, can be written as:

"the product of two numbers"

where the two numbers are the number x and the number y.

After that, we add the sum of these two numbers, then the complete sentence can be:

"the product of two numbers, plus the sum of these two numbers"
