Answer:

D. N = w² + 8w + 12

Step-by-step explanation:

The current size is w by w+4, so the area is ...

A = w(w+4)

When each dimension is increased by 2, the new size is (w+2) by (w+4+2). The latter dimension can be simplified to (w+6). Now, the new area is ...

N = (w+2)(w+6) = w² +8w +12 . . . . . . . matches choice D

Mark wants to use a grid to model the percent equivalent of the fraction 2/3. How many grid squares should be shade? What percen

Answer:

66 + 1 ( not fully shaded ) squares will be shaded.

66.67% region will be shaded

Step-by-step explanation:

It is given that Marks uses a grid to model percent equivalent of $\frac{2}{3}$ .

Let us assume that Mark uses a model containing 100 grids.

Now, as the grids are divided into region equivalent to $\frac{2}{3}$ i.e. it is divided into 3 parts.

Moreover, 2 out of those 3 parts will be shaded.

As, $\frac{2}{3} =0.6667$

i.e. $\frac{2}{3}$ =66.67%

So, it gives us that 66 squares in the grid will be fully shaded and one will not be fully shaded.

Hence, 66 + 1 ( not fully shaded ) squares will be shaded and in percent, 66.67% of the region will be shaded.

It took Sheldon 17 5/6 minutes to walk to Raj's house. The bus ride home took Sheldon 4 5/8 minutes. How many more minutes did i

MA_775_DIABLO [31]

Answer:

it will take her $13\frac{5}{24}$ minutes more to walk down to Raj's House

Step-by-step explanation:

It took Sheldon $17 \frac{5}{6}$ minutes to walk to Raj's house

It also took Sheldon $4\frac{5}{8}$ minutes to use the bus.

To get the time difference between the two transport mechanisms, we subtract their different time durations.

This will be

$17\frac{5}{6} - 4\frac{5}{8}=317/24$

We can convert this to Mixed fractions as shown $13\frac{5}{24}$ minutes.

Therefore, it will take her $13\frac{5}{24}$ minutes more to walk down to Raj's House
