Answer:
the last one with 2y in the denominator
x²/2 =271 represents the situation where taking length twice as breadth and area as 271 ft² .
Area of a figure is the amount of space acquired by the figure
Area of a rectangle=Length x breadth
length=x
breadth=x/2
Area of rectangular lawn=lxb
=x.x/2
But as per question,
Area=271 ft²
⇒x²/2=271 1
⇒x=23.28 ft²
Therefore, x²/2 =271 represents the situation where taking length twice as breadth and area as 271 ft² .Value of x i.e. length is 23.28 ft²

Answer:
D. y = 5/4x + 2 1/4
Step-by-step explanation:
The equation of the line is
y = mx + c
Step 1: find the slope
( 3 , 6) ( -1 , 1)
m = y2 - y1 / x2 - x1
m - is the slope of the line
( y1 , y2) - are point on the line
( x1, x2) - are point on the line
x1 = 3
y1 = 6
x2 = -1
y2 = 1
Inserting into the formula
m = y2 - y1 / x2 - x1
m = 1 - 6 / -1 - 3
m = -5/-4
Minus cancels minus
= 5/4
Step 2: substitute m into the equation of the line
y = mx + c
y = 5/4x + c
Step 3: sub any of the two points given into the equation
Let's pick ( 3 , 6)
x - 3
y - 6
y = 5/4x + c.
6 = 5/4(3) + c
6 = 5 * 3 / 4 + c
6 = 15/4 + c
c = 6 - 15/4
LCM = 4
c = 24 - 16 / 4
c = 9/4
c = 2 1/4
Step 4: sub c into the equation
y = 5/4x + c
y = 5/4x + 2 1/4
The equation of the line is
y = 5/4x + 2 1/4
Answer:
2
Step-by-step explanation:
First you divide 380 by 100 to get what 1% is, (3.8) and then you multiply by 18 to give you 18%. The answer is 68.4, so add that to 380 and you'll have the final answer of 448.4.
