Draw two different shapes with an area of 16 square units. What is the perimeter of each shape?

Answers


-- Rectangle, 1 unit wide, 16 units long
Area = 1 x 16 = 16 square units. 
Perimeter = (1 + 16 + 1 + 16) = 34 units.

-- Rectangle, 2 units wide, 8 units long
Area = 2 x 8 = 16 square units. 
Perimeter = (2 + 8 + 2 + 8) = 20 units.

-- Square, 4 units on each side
Area = 4 x 4 = 16 square units. 
Perimeter = (4 + 4 + 4 + 4) = 16 units.

-- Circle, Diameter = 4.515 units
Area = π R² = π (4.515/2)² = π (2.2575)² = 16 square units
Perimeter = circumference = π (diameter) = 4.515 π = 14.18 units

Step-by-step explanation:

The number of pages that Allen, Kevin, Roneisha, and Ben can read in a day is shown below. Allen read 15% of his 56-page book.
Kevin read 12% of his 64-page book.
Roneisha read 16% of his 42-page book.
Ben read 10% of his 72-page book.

Who can read the greatest number of pages in a day?

Answers

Allen read the greatest number of pages in a day.

What is the percentage?

The percentage is a ratio that can be expressed as a fraction of 100.

Allen read 15% of his 56-page book, therefore, the number of pages he read is:

15 %  of 56

= 15 × 56 /100

= 8.4

Kevin read 12% of his 64-page book, therefore, the number of pages he read is:

12% of 64

=12 ×64/ 100

= 7.68

Roneisha read 16% of his 42-page book, therefore, the number of pages she read is:

16% of 42

= 16×42/100

= 6.72

Ben read 10% of his 72-page book, therefore, the number of pages he read is:

10 % of 72

= 10×72/100

= 7.2

Note that Allen read the greatest number of pages in a day.

Allen : 0.15(56) = 8.4 pgs per day
Kevin : 0.12(64) = 7.68 pgs per day
Roneisha : 0.16(42) = 6.72 pgs per day
Ben : 0.10(72) = 7.2 pgs per day

Allen can read the greatest number of pages per day

What is the value of x if line a is parallel to line b and is cut by a transversal? x = 35

x= 19

x can not be determined from the information given

x = 27.25

Answers

Answer:

x=35

Step-by-step explanation:

These are alternate interior angles.  Since a and b are parallel, they are equal

5x - 54 = 3x+16

Subtract 3x from each side

5x-3x -54 = 3x -3x +16

2x -54 = 16

Add 54 to each side

2x-54+54 = 16+54

2x = 70

Divide each side by 2

2x/2 = 70/2

x = 35
