t=45min
d=4km
45min/60min = 0.75 hours
v=d/t
v=4km/0.75hours
v=5.33km/hour. So the answer is B. 45 minutes.
        
             
        
        
        
Answer:
9 : 1
Step-by-step explanation:
given a linear ratio = a : b, then the corresponding area ratio is
a² : b²
Here the linear ratio of their edges = 3 : 1, hence
ratio of surface areas = 3² : 1² = 9 : 1
 
        
             
        
        
        
Answer:
- 3, - 1, 1
Step-by-step explanation:
To find the first 3 terms substitute n = 1, 2, 3 into the formula
a₁ = 2(1) - 5 = 2 - 5 = - 3
a₂ = 2(2) - 5 = 4 - 5 = - 1
a₃ = 2(3) - 5 = 6 - 5 = 1
The first 3 terms are - 3, - 1, 1
 
        
             
        
        
        
Answer:
Unit of measure
Step-by-step explanation:
Unit of measure
When we construct any type of graph the unit of measure needs to be present, becuase the numbers without units are just numbers and with just the numbers we can't have physical interpretation of the situation.
For this reason is importatn to include the units of meausre with the plots since with that we have a point of reference for the variables used. 
And satisfy the condition "A standard of measure for a physical quantity and is included as part of the x and y axes labels on a line graph."
 
        
             
        
        
        
Option C  
<u>
Answer:
</u>
The equation in slope intercept form is 
The slope is  and y-intercept is
 and y-intercept is 
<u>Solution:
</u>
The slope - intercept form equation of line is given as
y = mx + c    ---- eqn(1)
Where m is the slope of the line. The coefficient of “x” is the value of slope of the line.
c is the y – intercept which is the value of y at the point where the line crosses the y-axis
From question, given that -5x - 12y = 11 --- eqn (2)
On converting equation (2) in slope – intercept form, that is adding 5x on both sides,
-5x - 12y + 5x = 5x + 11
-12y = 5x + 11
Now on dividing -12 on both sides,
 ---- eqn (3)
     ---- eqn (3)
Comparing the given equation (3) with equation (1), we get  
 and
 and 
Hence Option C is correct.
