Anastaziya [24]

Answer:

Maria

Step-by-step explanation:

Find the ratio of powdered mix to water for each drink.

For Maria:

(2/3 cup) / (2 gallon)

= 1/3 cup per gallon

For Franco:

(1 1/4 cup) / (5 gallon)

= (5/4 cup) / (5 gallon)

= 1/4 cup per gallon

Since 1/3 is bigger than 1/4, Maria's sports drink is stronger.

coldgirl [10]

Answer: Explanatory variable = " number of times the owner has an advertisement played on the radio"

Response variable = "number of new customers who will visit a shop"

Step-by-step explanation:

What is the area of this figure?
ludmilkaskok [199]

Answer:

          \large\boxed{\large\boxed{42 unit^2}}

Explanation:

The figure is not a regular hexagon. It is an irregular hexagon.

Please, find attached the picture with the original question and the figure.

You can split the figure into two triangles and one rectangle.

The rectangle has dimensions: 7units × 4units, thus its area is 28 units².

Both the upper triangle and lower triangle have base 7 units and height 2 units.

Hence the area of each triangle is:

       area=(1/2)base\times height

       

      area=(1/2)7units\times 2units = 7units^2      

Hence, the area of the hexagon is:

           28units^2+7units^2+7units^2=42units^2
