Answer:
Option A
y=-4/3x+7
Step-by-step explanation:
To solve this, we need to understand the various components of the equation of a straight line. 
A straight line has the equation: y =mx + c
<em>m</em> is the slope and<em> c</em> is the intercept on the y-axis. If we can get these two components, we can figure out the equation for the new line.
Calculating the slope, <em>m</em>
To obtain the slope of the new line, we use the fact that it is perpendicular to the slope of the line y = 3/4x-2. 
This means that 
3/4 X <em>m</em> = -1
<em>m</em> = -4/3
To obtain the intercept, <em>c</em>
The intercept can be obtained by adding 3 to the y-component of (0, 4).
This will give (0, 7). Hence the intercept c will be 7.
Therefore, the equation of the line will be y = -4/3x+7. Option A
 
        
             
        
        
        
Step1: Find the area of the triangular lawn
              Given, base of the triangle is y metres and the height is z metres
              Area of the triangle = 
2
1
 × base × height
              Therefore, area of the triangular lawn =

Step 2:Find the cost of planting the grass
              Rate of planting the grass is Rs. x per square metre.
              Therefore, the cost of planting the grass on a triangular lawn =cost per square meter × area of the triangular lawn
               =x×

1) This sequence of numbers is arithmetic, because each number is the previous one divided by two. 
2) the next number in the sequence is 125/2, which is 62.5
        
             
        
        
        
Answer:
25.12
Step-by-step explanation:
the formula of a cone is pi r^2 * h/3
r = radius and h = height
the radius is 2 and the height is 3
and the question says use 3.14 instead of pi so
we have
3.14 * 2^2 * 6/3
2*2 or 2^2 = 4
3.14 * 4 * 6/3
6/3 = 2
3.14 * 4 * 2
4*2 = 8
and 8 * 3.14 is 25.12
