3 ounces of 80-proof rum approximately contains 200,000 cal.
Now, we need to convert the cal into kcal. We know that:
1 cal = 1000 kcal
Therefore,
200,000 cal = 200 kcal
Answer:
The resulting equation is
x^2/4+16x^2/9=1
Step-by-step explanation:
The given equations are:
3y=12x eq(1)
x^2/4+y^2/9=1 eq(2)
We need to isolate variable y in equation 1
Divide both sides of the equation with 3
3y/3 = 12x/3
y = 4x
Now, substitute the value of y=4x in second equation
x^2/4+y^2/9=1
x^2/4 + (4x)^2/9 = 1
The resulting equation is
x^2/4+16x^2/9=1
Your classmate is correct, though this is not explicitly what the midpoint formula is necessarily set out to do. If one is given two sets of endpoints, one can discover the midpoint by finding the mean distance between these two endpoints. For example, if two points are 10 and 2, all you need do to find the midpoint is add the two poles and divide them by 2 (that is, find the average). The same applies for coordinate geometry, except with additional variables, the formula to find the coordinates of a midpoint is: M= (x1+x2/2, y1+y2/2). Thus, two averages (of both the x coordinates and y coordinates are taken). Your classmate is correct if two endpoints are given, think of a line with two poles, the middle of this line must be the midpoint.
Answer:
The total cost of painting the curved surface area of all pillars at the rate of Rs 10 per square meter is Rs.554400.
Step-by-step explanation:
Given : In a building there are 30 cylindrical pillars. The radius of each pillar is 42 m and height is 7 m.
To find : The total cost of painting the curved surface area of all pillars at the rate of Rs 10 per square meter ?
Solution :
Radius of each pillar r= 42 m
Height of each pillar h= 7 m
The curved surface area of each pillar is 
Substitute the value,
Area of 30 pillars is given by,
The curved surface area of all pillars at the rate of Rs.10 per square meter.
The cost painting is 
Therefore, the total cost of painting the curved surface area of all pillars at the rate of Rs 10 per square meter is Rs.554400.
