Answer:

If two angles are supplementary, their sum is 180 degrees.

Check: 10 + 170 = 180

=> Maryam's claim is correct

If two angles are complementary, their sum is 90 degrees.

Check: 81 + 9 = 90

=> Ailia's claim is correct

As the definition:

Vertical angles have sides that form two pairs of opposite rays.

Adjacent angles have a common side and don't overlap.

=> As provided pair of angles, they are adjacent pair of angles.

=> Ahmed's statement is wrong, Saalem's statement is correct.

Hope this helps!

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

natka813 [3]

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.

You originally draw a design for an art contest on a 2 in. x 5 in. card. The second phase of the contest requires the drawing to

pentagon [3]

The correct answer is: 
4.2 inches.

Explanation: 
We use the size of the largest dimension of the reproduction to find the scale factor. The largest dimension of the original drawing was 5 inches.
The largest dimension of the reproduction is 11 inches.

To find the scale factor, divide: 
 $\frac{11}{5}$ =2.1.

Since the scale factor is 2.1, to find the smallest dimension of the reproduction we multiply the original by 2.1:
2*2.1=4.2 inches.
