Answer:

Option C is correct.

1\frac{1}{3} square yards

Step-by-step explanation:

Use conversion:

1 ft = 3 yards.

As per the statement:

Some pleated draperies must be twice as wide as the window they cover.

it is also given that window 2 ft. wide and 3 ft. long

The draperies must be 4 ft wide = \frac{4}{3} yard (twice the window width) and 1 yards long

Area of material needed to cover the window= l \times w

where w is the wide and l is the length respectively.

then;

Area of material needed to cover the window = \frac{4}{3} \cdot 1 = \frac{4}{3} = 1\frac{1}{3} square yards.

Therefore, 1\frac{1}{3} square yards of material are needed to cover this kind of window 2 ft. wide and 3 ft. long.

The window is 2/3 yd by 1 yd, so its area is
.. area = length*width = (2/3 yd)*(1 yd) = 2/3 yd^2

Double that amount of material would be 4/3 yd^2 = 1 1/3 yd^2.

Vikki [24]

Answer:

200g of sugar, 600g of flour, 400g of butter

Step-by-step explanation:

50g sugar = 15 biscuits

3 x 50g = flour --) 150g = flour

2 x 50g = butter --) 100g = butter

60/15 = 4; 4 times as much

4 x 50g = 200g of sugar

4 x 150g = 600g of flour

4 x 100g = 400g of butter

What is the perimeter of the shape below, given a = 9.60, b = 9.33, c = 4.46, d = 8.56, e = 8.61
GalinKa [24]

Answer:

The perimeter of the shape is of 40.56 units.

Step-by-step explanation:

Perimeter of a shape:

The perimeter of a shape is the sum of the lengths of all its sides.

In this question:

The sides are a = 9.60, b = 9.33, c = 4.46, d = 8.56, e = 8.61.

So

P = a + b + c + d + e = 9.6 + 9.33 + 4.46 + 8.56 + 8.61 = 40.56

The perimeter of the shape is of 40.56 units.

The dot plot displays the number of marshmallows added to hot cocoa by several kids. What is the MAD of the data represented in
Pie

  Mean absolute deviation (MAD) of the data set indicates the average distance of all elements from mean of the data set.

MAD of the data represented by dot plot in the picture will be Option A.

Elements in the given dot plot are,

3, 4, 5, 5, 5, 5, 5, 5, 6, 7

Steps to be followed for the mean absolute deviation of this data set.

  • Find the mean of the data set
  • Find the absolute distance of each element from the mean
  • Find the average distance of all the elements which will be MAD of the data set.

Step - 1 :

Mean of the data set = \frac{\text{Total of the data}}{\text{Total number of elements}}

                                   = \frac{3+4+5+5+5+5+5+5+6+7}{10}

                                   = \frac{50}{10}

                                   =5 (As shown on the dot plot)

Step - 2 :

Absolute distance of each element from the mean of the data set,

3 - 5 = |-2| = 2

4 - 5 = |-1| = 1

5 - 5 = 0

5 - 5 = 0

5 - 5 = 0

5 - 5 = 0

5 - 5 = 0

5 - 5 = 0

6 - 5 = 1

7 - 5 = 2

Step - 3 :

Average of the absolute distance = \frac{2+1+0+0+0+0+0+0+1+2}{10}

                                                        = \frac{6}{10}

                                                        = 0.6

          Therefore, Option A will be the correct option.
