Answer:
The dimensions of rectangle are
Length: 15 meters
Breadth: 12 meters
Step-by-step explanation:
Let
x ----> the original length of rectangle
y ---> the original breadth of rectangle
The area of rectangle is
1) The area of a rectangle reduces by 20 m2, if its length is increased by I m and the breadth is reduced by 2 m
Remember that
substitute
-----> equation A
2) The area increases by 12 m², if the length is reduced by 3 m and the breadth is increased by 4 m.
Remember that
substitute
-----> equation B
Solve the system of equations A and B by substitution
substitute equation A in equation B
solve for x
Find the value of y
therefore
The dimensions of rectangle are
Length: 15 meters
Breadth: 12 meters
Answer:
12-issue subscription
Step-by-step explanation:
18-issue sub = $40.50 ÷ 18 = $2.25/issue
12-issue sub = $33.60 ÷ 12 = $2.8/tissue
=> The 12-issue subscription costs more per issue (2.8 > 2.25)
Answer:
2727
Step-by-step explanation:
The formula for finding the volume of a cone is
1/3πr²h
The radius would be 11.5 because, radius equals the diameter divided by two.
So, first you would plug your numbers into the equation
1/3(π)(11.5)²(19.7)
*use 3.14 for pi
Then multiply.
V = 2726.9 (2727 if you round to the nearest whole number)
Answer:
A: 4/8
Step-by-step explanation:
1/2 is the same as 4/8 because if we divide 4 to both the numerator (4 divided by 4) and the denominator (8 divided by 2), we get 1 for the numerator and 2 for the denominator.
The answer is -5 hope this works
