Answer:
28
Step-by-step explanation:
We know that the heights and bases of all of the parallelograms will be the same because they are equal, therefore, since the height of 2 parallelograms is 14, the height of one parallelogram is 14 / 2 = 7. Since the areas of all of the parallelograms are congruent, the area of one parallelogram is 308 / 4 = 77. The parallelogram area formula is A = bh where A, b and h are area, base and height respectively and we know both the area and height so we need to solve for b. Doing so we get 77 = b * 7 so that means b = 11. The length of y is two bases + 6 and since we know the base is 11, y = 11 * 2 + 6 = 22 + 6 = 28.
The fraction 1/2 converts to 0.50 in decimal form.
The mixed number 15 & 3/4 is the same as 15.75
If Calvin is distracted, then he makes 15.75-0.50 = 15.25 pizzas per hour on average.
Multiply by 8 to find the total number of pizzas possible.
8*15.25 = 122
<h3>Answer: Calvin can make 122 pizzas overall if he is distracted</h3>

Answer:
area of a circle is = 78.5units²
Step-by-step explanation:
to evaluate for the area of a circle whose diameter = 10
π = 3.14
recall that the area of a circle is = πr²
since we were given diameter
note that diameter = 2 x radius
radius = diameter / 2
radius = 10/2
radius = 5units
area of a circle is = πr²
area of a circle is = 3.14 x (5)²
area of a circle is = 3.14 x 25
area of a circle is = 78.5units²
