Answer:
C. $412.50
Step-by-step explanation:
We can use proportion:
12 meals --- 3 pounds
250 meals --- x pounds
x=(250 meals*3 pounds)/12 meals = 62.5 pounds
62.5 pound * $ 6.60/pound = $ 412.50
4,4,4,5,5,5,6,6,7,8,8,8,9,10,10,10,10
It is the number 7.
Answer
Perimeter = 1.75 times larger
Area = 3.0625 times larger
Step-by-step explanation:
Let the original quadrilateral have sides of a, b, c, d
Perimeter of the New Photograph
- Then the perimeter of the original is P = (a + b + c + d)
- Now the perimeter of the new quad is P = 1.75a + 1.75b + 1.75c + 1.75d
- Using the distributive Property we get P = 1.75(a + b + c + d) So the new perimeter is 1.75*the old perimeter.
Area of the New Photograph
The area is a little harder. Suppose the Old figure had an Area found by the formula of
- Area = e * f Each measurement is increased by a factor of 1.75
- Area_new = 1.75e * 1.75f
- Area_new = 3.0625 * e * f
- Area_new = 3.0625 * old area
The expression 11x^2 - 12x - 10 has 3 terms and a constant of 10.
