Answer:
39.63
Step-by-step explanation:
If the number after the place you are rounding to is 4 or lower, then you round down. If it is 5 or higher round up.
The value of the scale factor is 3. Then the height and area of the triangle ΔABC will be 9 ft and 54 square ft.
<h3>What is dilation?</h3>
Dilation means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.
The area of the triangle ΔDEF is 6 square ft. And the base length of the triangle ΔDEF is 4 ft.
The area of the triangle is given as
Then the height of the triangle ΔDEF will be
Then the scale factor will be
Then the height of the triangle ΔABC will be
Then the area of the dilated triangle ΔABC will be

The equation that can be used to represent this context is 75 = 40 + 3.5x.
<h3>Description of the reward points </h3>
The reward points Arianna receives are divided into two. They are the fixed reward point and the variable reward points. The fixed reward point is the point that she receives when she signs up. The variable reward point is the point that increases with going to the movie theater.
Total reward points = the fixed reward point + variable reward points
Total reward points = 40 + 3.5xx
75 = 40 + 3.5xx

Answer: 50yd
Step-by-step explanation:
We know that the area of any rectangle is length times width. The perimeter is the sum of twice the length and twice the width.
Let width = x
Let length = 4x
Area = 100m2
Next, we can write an equation using these variables and formula for area.
4x2 = 100
x2 = 25
x = -5 and x = 5
Since the dimensions cannot be negative, we accept the positive value:
x = 5
Next, we can substitute this value of x into the variables.
width = 5 m
length = 20 m
Finally, we can find the perimeter by plugging in these dimensions into the perimeter formula,
Perimeter = 2(5 m) + 2(20 m)
= 10 m + 40 m
= 50 m
