Answer:
9.74%Step-by-step explanation:
Total population
7 × 10^9Let handed population
682 000000Percentage 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

If a quadratic function has the rule
f(x) = (x – h)? + k,
what will cause a horizontal translation?
A, changing the value of h
B, changing the value of k
A. Changing the value of h will cause horizontal translation.
What is transformation ?Transformations are of many types like translation, rotation, reflection and dilation.These transformations are of two types rigid transformation where the shape and size of image and pre image remains same and another one is non-rigid transformation in which size changes but shape of doesn't change.
We know that a quadratic function can be represented by a 2D co ordinate which has x axis and y axis.
Given a function f(X) = ( x - h) + k will cause horizontal transformation of h units to the left.

Solve for y
5/8y = -1
Answer:
y = -8/5
Step-by-step explanation:
Step 1: Write equation
5/8y = -1
Step 2: Solve for y
Divide both sides by 5/8: y = -8/5Step 3: Check
Plug in y to verify it's a solution.
Substitute: 5/8(-8/5) = -1Multiply: -40/40 = -1Divide: -1 = -1Parallelogram JKLM has angle measures J(2 x +9) and M(6 x -1) determine the measure of angle k
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

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
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.

Jesse took in 50 pounds of copper, 15 pounds of aluminum and 10 pounds of plastic. How much money was he paid for his recyclables?
Answer:
100.25
Step-by-step explanation:
You multiply the amount the copper cost by however many pounds of it he brought in you do this to the others as well but of course theres different numbers for example it would be like this.
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!!
