Answer:
30
Step-by-step explanation:
We require to calculate the volume of 1 brick
V = lbh ( l is length, b is breadth and h is height ), that is
V = 14 × 8 × 5 = 560 cm³
Now divide the volume of concrete available by the volume of 1 brick.
number of bricks made =
= 30
Answer:

Step-by-step explanation:
Let
x ----> the height of the top of a mountain above sea level
y ----> the deep of a shipwreck below the sea level
we know that
The sea level represent the height equal to zero
In this problem we have
---> is positive because is above sea level
---> is negative because is below sea level
To find out the distance between the mountain top and the ship wreck, determine the absolute value of the difference between the two values

substitute the values

Step-by-step explanation:
i took a test with the same question
Answer:
(a) The slope of f(x) is greater than the slope of g(x)
(b) f(x) has a greater y intercept
Step-by-step explanation:
Given


Solving (a): Compare the slopes
The slope (m) of f(x) is calculated as;

This gives:


Substitute values for f(0) and f(1)



The slope of g(x) can be gotten using the following comparison


So:



Solving (b): Compare the y intercept
y intercept is when 
From the table of f(x)

From the equation of g(x)

We can see that the 33 degrees corresponds to angle A (parallel lines) meaning they’re equal.
This means that 33 + 2x = 5x (5x is the exterior angle, so the other two interior angles’ sum must equal to it)
3x = 33
x = 11
