dangina [55]

Answer: The fraction of the gifts were for birthdays = $\dfrac{33}{100}$ .

Step-by-step explanation:

Given: fraction of gifts for weddings = $\dfrac{3}{10}$

Rest of the gifts = $1-\dfrac3{10}-\dfrac{37}{100}$

$=\dfrac{100-30-37}{100}\ \ \ [\text{Making like fractions}]\\\\=\dfrac{100-67}{100}\\\\=\dfrac{33}{100}$

Hence, the fraction of the gifts were for birthdays = $\dfrac{33}{100}$ .

What is the perimeter of the polygon defined by the points A(12, 20), B(20, 20), C(20, 8), and D(12, 8)? a 64 units b 144 units

Rzqust [24]

Answer:

d. 40 units

Step-by-step explanation:

The length of the horizontal side of this rectangle on the line y=20 is the difference of the x-coordinates, 12 and 20, so is 8. The length of the vertical side on the line x=20 is the difference of the y-coordinates, 20 and 8, so is 12.

Two sides are of length 8 and two are of length 12. The perimeter is the sum of the side lengths, so is ...

P = 2·8 +2·12 = 40 . . . units
