Let's say that BC is x, so that AB is 4x, and AE = y.

The shaded area then is represented by 4xy/2 = 2xy.
The total area is represented by (4x+x)*y = 5xy.

The fraction of these is 2xy/5xy = 2/5.

Answer: Total cost to make 12 pennants is $52.5.

Step-by-step explanation:

Since we have given that

There is a rectangle and a triangle.

Length of rectangle = 1 ft

Width of rectangle = 3 ft

So, Area of rectangle is given by

$Area=Length\times Breadth \\\\Area=1\times 3\\\\Area=3\ ft^2$

Base of triangle = 1 ft

Height of triangle = 1 ft

So, Area of triangle is given by

$Area=\frac{1}{2}\times base\times height\\\\Area=\frac{1}{2}\times 1\times 1\\\\Area=\frac{1}{2}\ ft^2$

So, Total area of the pennants will be

$3+\frac{1}{2}\\\\=\frac{6+1}{2}\\\\=\frac{7}{2}\ ft^2$

Number of pennants = 12

Cost per square foot of pennant = $1.25

So, Total cost for 12 pennants is given by

$12\times \frac{7}{2}\times 1.25\\\\=\$52.5$

Hence, Total cost to make 12 pennants is $52.5.

in a salad with vegetables containing 50 calories dressing is added at 100 calories per ounce. The total number of calories can

Vika [28.1K]

Answer:

Step-by-step explanation:

To get the reasonable range of the situation, we will find the minimum value and maximum value of the calories that can be dressed.

The minimum occur at when x = 0

f(0) = 100(0) +50.

f(0) = 50

Hence the minimum value of the calorie is 50.

The maximum value occur at f'(x)

f'(x) = 100

Hence the maximum value of the calorie is 100

Hence, the reasonable range for the situation is 50 ≤ x ≤ 100
