Helppp this is my math test <br><br> Which model is 85% shaded?

Anettt [7]

Answer:

Model 1 represents 85% shaded area.

Step-by-step explanation:

Here, each model consists of equal sized rectangles.

Please refer to attached figure to know the model number.

Model 2 (on top right of question figure) contains a total of 20 such rectangles out of which 13 are shaded. As per formula of percentage:

$\text{Percentage of shaded area} = \dfrac{\text{Number of shaded rectangles}}{\text{Total number of rectangles}} \times 100\\\Rightarrow \dfrac{13}{20}\times 100 = 65\%$

Model 3 (on bottom left of question figure) contains a total of 16 such rectangles out of which 10 are shaded. As per formula of percentage:

$\text{Percentage of shaded area} = \dfrac{10}{16}\times 100 = 62.5\%$

Model 4 (on bottom right of question figure) contains a total of 16 such rectangles out of which 13 are shaded. As per formula of percentage:

$\text{Percentage of shaded area} = \dfrac{13}{16}\times 100 = 81.25\%$

Model 1 (on top left of question figure) contains a total of 20 such rectangles out of which 17 are shaded. As per formula of percentage:

$\text{Percentage of shaded area} = \dfrac{17}{20}\times 100 = 85\%$

Hence, model 1 is the correct answer.

Robert had some friends at his house after school. His mom cut up 2 pies for them to eat. If she cut each pie into fourths, how

marta [7]

Answer:

8/8

Step-by-step explanation:

There are two pies, and each one was cut into fourths. There are four fourths in a whole, and since there are two wholes, there are two four fourths (I don't know if this makes sense).

Basically, multiply how many fourths (four per pie) by how many pies there are.

4 x 2 = 8

There are 8 pieces.
