PS:its not 50,20,10,30,60,90,180,5,2, or 11

Answers

Answer 1

Answer:

x = 2

The smaller angle = 20

The larger angle = 70

Step-by-step explanation:

1/4 of a circle is 90 degrees

90 = 10x+ 20x+30

Combine like terms

90 = 30x+30

Subtract 30 from each side

90-30 = 30x+30-30

60 = 30x

Divide each side by 30

60/30 = 30x/30

2= x

10x = 10*2 = 20

20x+30 = 20*2 + 30 = 30+30 = 70

Answer:

100.25

Step-by-step explanation:

Copper=1.48x50=$74.00

Aluminum=1.55x15=$23.25

Plastic=0.30x10=$3.00

Then add those numbers together to get the amount of money he made off of his recyclables. Which the number you would get is 100.25 Hope this helps!!

the estimated world population in 2011 was 7 x 10^9. Of the total population, 682 million of those people were left handed. Approximately what percentage of the world population is left handed according to the 2011 estimation

Answers

Answer:

9.74%

Step-by-step explanation:

Total population

7 × 10^9

Let handed population

682 000000

Percentage of left handed population

100%×682000000 / (7×10^9) =6.82×10^10/ (7 × 10^9) % =68.2/7 % = 9.74%

Answer:

9.7 %

Step-by-step explanation:

estimated world population in 2011 = 7x10⁹

left handed = 682,000,000

find:

Approximately what percentage of the world population is left handed according to the 2011 estimation

percentage = left handed population

total population

= 682,000,000

7,000,000,000

= 0.682

7.0

= 9.7 %

A landscape architect used the entire length of an 80-foot rope to lay out a flower bed in the shape of a square. In another area, he used the entire
length of the same rope to lay out a second flower bed in the shape of a circle. (Drawings not to scale.)
Exhit
Perimeter 80 feet
Circumference - 80 feet
What is the area of the circle?
A 125.6 ft2
B. 2,041.8 ft2
c. 215.2 ft
D. 506.5 ft2

Answers

A square has 4 sides so 80/4= 20ft
area= 20^2
area=400 square ft

2*3.14*r = 80
r = 80/6.28
r=12.74 ft

area= A = 3.14*12.74^2
A = 509.6 sq/ft

if you wanted to find the difference:

509.6 - 400 = 109.6 sq/ft more in the circle

The area of the circle with a perimeter of 80 feet is 509.31 square feet.

The entire length of the rope = 80 feet

So, the perimeter of the flower bed = 80 feet

Since the flower bed is in a square shape

So, the perimeter of the square = The entire length of the rope

The perimeter of the square = 80 feet

Suppose the side of the square is a

So, 4a = 80

a =20

So, the area of the square = 20² = 400 square feet.

What is the area of a circle?

The area of a circle with a radius r is πr².

Similarly, when the flower bed is in a circular shape

The perimeter of the circle = 80

Suppose the radius of the circle is r

So, [tex]2\pi r =80\\\\[/tex]

[tex]r= 12.73 feet[/tex]

Area of circle = [tex]\pi r^{2}[/tex]

Area of circle = 509.31 square feet.

Therefore, the area of the circle with a perimeter of 80 feet is 509.31 square feet.

Parallelogram JKLM has angle measures J(2 x +9) and M(6 x -1) determine the measure of angle k

Answers

Answer:

Step-by-step explanation:

The sum of opposite angle and sides of a parallelogram is 180 . If a parallelogram JKLM has angle measures J(2 x +9) and M(6 x -1), then <J + < M = 180

Substitute:

2 x +9+6x-1 = 180

collect like terms;

2x+6x+9-1 = 180

8x+8 = 180

8x = 180-8

8x = 172

x = 172/8

x = 21.8°

For the shape to be a quadrilateral, then the measure of angle k must 128 degrees

For quadrilateral PQRS to be an actual quadrilateral, then:

[tex]K = M[/tex] --- opposite angles of quadrilateral[tex]J + M= 180[/tex] --- adjacent angles of quadrilateral

[tex]J + M = 180[/tex] implies that:

[tex]2x + 9 + 6x -1 = 180[/tex]

Collect like terms

[tex]2x + 6x = 180 -9 +1[/tex]

[tex]8x = 172[/tex]

Divide both sides by 8

[tex]x = 21.5[/tex]

We have:

[tex]K = M[/tex]

This becomes

[tex]K = 6x -1[/tex]

Substitute 21.5 for x

[tex]K = 6\times 21.5 -1[/tex]

[tex]K = 129 -1[/tex]

Subtract 1 from 129

[tex]K = 128[/tex]

Hence, the measure of angle K must be 128 degrees
