A recycling center was offering cash for different types of recyclables. For each pound of copper they paid $1.48, for each pound of aluminum they paid $1.55, and for each pound of plastic they paid $0.30. 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!!

50 POINTS WILL GIVE BRAINLIEST Use the drawing tools to form the correct answer on the grid. Caroline is planting flowers in her garden. She plants her first 7 flowers in 4 minutes. After 12 minutes, she has planted 21 different flowers. Plot four data points and the line of best fit to model how long it takes Caroline to plant flowers.
Answer:
(4, 7)(12, 21)(7, 12.25)(21, 36.75)Step-by-step explanation:
The y axis shows the number of flowers planted.
The x axis shows the number of time that passes in minute.
She plants her first 7 flowers in 4 minutes.
7 represents the number of flowers planted so that will be the y coordinate.
4 minutes represents the number of time that passes so that will be the x coordinate.
(4, 7) will be the first point.
After 12 minutes, she has planted 21 different flowers.
12 minutes represents the number of time that passes so that will be the x coordinate.
21 represents the number of flowers planted so that will be the y coordinate.
(12, 21) will be the second point.
We can find the unit rate that she plants flowers in.
7 / 4 = 1.75 flowers per minute
21 / 12 = 1.75 flowers per minute.
If we divide or multiply this value to the x and y coordinates, we can find new points.
Lets multiply 1.75 to (4, 7)
(4 * 1.75, 7 * 1.75)
(7, 12.25)
Lets multiply 1.75 to (12, 21)
(12 * 1.75, 21 * 1.75)
(21, 36.75)
Best of Luck!

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
7,000,000,000
= 0.682

Answer:

Step-by-step explanation:
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.

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.
