Answer:
y = 
x - 5
y = 2x + 5
Step-by-step explanation:
In linear equations, both variables x and y must have the exponent of 1 (i.e. they cannot have a small number at the top-right). And they cannot be in the exponents (i.e. cannot be the small number at the top-right).
Answer:
2.718
Step-by-step explanation:
The thousandths place is 3 to the right of the decimal (the 8).
Since the next number is 2, the number stays the same and does not round up.
Hope this helps :)
The world population is estimated to be nearly 9 billion by the year 2050.
Africa- 20%
What is the estimated population of Africa in the year 2050?
9 billion x 0.2 = 1.8 billion
You have 3 spheres inside a cylinder like for a can of tennis balls. Notice the radius of the cylinder is 3 cm, the same as the radius of the spheres, so the spheres just fit width wise, and 3 spheres height would be 6 radius lengths or 18, which is the same as the cylinder height, so the three spheres are packed to the best fit.
The volume not occupied by the spheres will be the total cylinder volume take away the three spheres volumes.
The cyinder volume with height h=18 and radius r=3 will be approx..
The volume of 3 spheres with radius r=3 will be
The volume unoccupied by the spheres inside the cylinder is the difference in those two volumes..
508.68 - 339.12 = 169.56 or 170 cubic centimeters
The answer is B that's what I got. Note: Anytime it says per just know that it's going to have a variable with it. :)
