In the late nineteenth century, the scientist Marie Curie performed experiments that led to the discovery of radioactive substances. A radioactive substance is a substance that gives off radiation as it decays. Scientists describe the rate at which a radioactive substance decays as its half-life. The half-life of a substance is the amount of time it takes for one-half of the substance to decay. Radium has a half-life of 1600 years. How much radium will be left from a 1000-gram sample after 1600 years?
Answer:
Step-by-step explanation:
Half life is the time taken by a radioactive substance to reduce of half of its original size
If the half life of radium is 1600, this means that the original radioactive substance N0 have reduced to N0/2 after 1600 years
if we are given N0 = 1000grams
The amount of the substance that will remain after 1600 years will be N0/2 i.e 1000/2 = 500g
Hence 500 grams of radium will be left after 600years

(a)identify and describe the error
(b)recalculate the Medicare bill
Answer:
$544.5
Step-by-step explanation:
a) 12 minutes is 0.2 hours.
So 3/0.2= 15 patients.

Moretti's Ristorante & Pizzeria has two different soda sizes, Regular and Large. The Regular size soda is 22 ounces and the Large soda is 64 ounces. By what percent does the amount of soda increase between the different soda sizes? Round to the nearest percent
Answer:
280
Step-by-step explanation:
Given that:
The two different sizes of soda are:
Regular = 22 ounce
Large = 62 ounce.
The objective is to determine by what percent does the amount of the soda increase between the different soda size.
i.e. The ratio of the larger size in respect to the regular size:
So,
62/22 = 2.82
Thus in percent, the amount of the soda increase between the different soda size = 2.82 × 100%
= 282 percent
To the nearest percent, it is = 280
Charlie bought hamburgers today and drinks for his friends. Each burger cost $3.75 and each drink cost .50 cents. In total Charlie paid $25.50 for his order. Write an equation that represents the number of burgers he bought,h, and the number of drinks he bought ,d.
Answer:
3.75h + 0.5d = 25.50
Step-by-step explanation:
Let 'h' represent the number of hamburger.
Let 'd' represent the number drink.
From the question given:
We were told that a hamburger (h) cost $ 3.75.
Therefore, h number hamburger will cost = h × 3.75 = 3.75h
Also, we were told that a drink cost 0.50 cent.
Therefore, d number of drink will cost = d × 0.5 = 0.5d
In total Charlie paid $25.50 for his order i.e
Total cost of hamburger + total cost of drink = 25.50
Total cost of hamburger = 3.75h
Total cost of drink = 0.5d
3.75h + 0.5d = 25.50
Thus, the equation representing the number of hamburgers (h) and the number of drinks (d) that Charlie bought is given as:
3.75h + 0.5d = 25.50
The value of x must be greater than 0 1 03

Of the American Indian cultures that lived in Georgia, the Woodland Indians were the FIRST to A.Adopt a primarily nomadic lifestyle. B.Acquire much of the food they needed through farming. C.Construct homes using animal skins. D.Encounter and develop trade relationships with Europeans.
Answer:
Acquire much of the food they needed through farming.
Step-by-step explanation:
The term woodland Indians was one that was created around the year 1932, to describe a certain culture that was quite different from the nomadic Archaic Indians that moved around the North American continental areas.
The woodland cultures were known for the cultivation of beans, squash and corn (maize). They were also involved with the creation of unique pottery styles and the building of burial mounds.
the points on the table lie on a line FInd the slope of the line (x- (-2), 0, 2, 4) (y- 3,4,5,6)
Answer:
Slope= 1/2
Step-by-step explanation:
The slope of the given line is 0.5.
What is the slope of the line?The slope of a line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
The points on the table lie on a line, as follows;
x: (-2), 0, 2, 4
y: 3,4,5,6
To determine the slope of a line, you can use the formula:
(change in y)/(change in x)
As per the points in the table,
the change in x is (4-(-2)) = 6, and the change in y is (6-3) = 3.
Slope = (3)/(6)
Slope = 1/2
Apply the division operation, and we get
Slope = 0.5
Therefore, the slope of the line is 0.5.

32 is 56% of what number?
Answer:
About 57.14285714, or 57 1/7 (400/7)
Step-by-step explanation:
Suppose the answer is x. This would mean that x multiplied by 0.56 (56%) would equal 32. To isolate x, you would have to divide both sides by 0.56, making the answer 32/0.56, or About 57 and 1/7

TO find perpednicular you take the negative reciprical of the slope, so the reciprical of -4/3 is -3/4, now add the negative to get - - 3/4 or 3/4
The length of a rectangle is given by 6t + 5 and its height is √t, where t is time in seconds and the dimensions are in centimeters. Find the rate of change of the area with respect to time.
A'(t) =???
MARK AS BRAINLIST
Step-by-step explanation:
L = 6t+5
H = √t
A = L*H
= (6t+5) *√t = 6t√t + 5√t
A'(t) = 6t * 1/2*√t + √t * 6 + 5/2*√t
= 6t/2√t + 6√t + 5/2√t
Expression for the rate of change of the area with respect to time will be,
A' = [tex]9t^{\frac{1}{2}}+\frac{5}{2}t^{-\frac{1}{2}}[/tex] cm per second
It's given in the question,
Length of a rectangle is given by the expression(6t + 5) cm
Width or height of the rectangle is given by the expression,[tex]\sqrt{t}[/tex] cm
Area of the rectangle is given by,
Area = Length × Height
A = (6t + 5)(√t)
A = [tex]6t^{\frac{3}{2}}+5t^\frac{1}{2}[/tex]
Now find the derivative of area (A) with respect to time (t).
[tex]\frac{dA}{dt}=\frac{d}{dt}(6t^{\frac{3}{2}}+5t^\frac{1}{2})[/tex]
A' = [tex](6\times \frac{3}{2})t^\frac{1}{2}+\frac{5}{2} t^{-\frac{1}{2}}[/tex]
A' = [tex]9t^{\frac{1}{2}}+\frac{5}{2}t^{-\frac{1}{2}}[/tex]
Therefore, expression for the rate of change of the area will be,
A' = [tex]9t^{\frac{1}{2}}+\frac{5}{2}t^{-\frac{1}{2}}[/tex]
