The half-life of a radioactive substance is 200 years. There are 8000 grams of the substance initially. How many grams of the substance are left after 300 years?
a) 5039.684g
b) 2828.427g
c) 3000g
d) 2000g
Answer:
There are 2,000 grams left after 300 years.
Step-by-step explanation:
Giving the following information:
The half-life of a radioactive substance is 200 years. There are 8000 grams of the substance initially.
First, we need to calculate the reduction of the substance each year:
Yearly reduction= 8,000/400= 20 grams per year
Now, for 300 years:
300 year reduction= 20*300= 6,000
There are 2,000 grams left after 300 years.

Find the sum of the measures of the exterior angles of a convex 55-gon.
A 6.55
B 360
C 180
D 90
Answer:
B 360
Step-by-step explanation:
i have Mrs. Dunn
Sum of the measures of the exterior angles of a convex 55-gon is equal to 360.
What is the polygon?A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end. Thus, the line segments of a polygon are called sides or edges.
here, we have,
An exterior angle is an angle between a side of a polygon and an extended side adjacent to it.
A polygon refers to any closed curve comprised of a set of connected sides such that no two sides cross.
Convex 55-gon means a convex polygon with n sides.
The sum of measures of any polygon is equal to 360
So, the sum of the measures of the exterior angles of a convex 55-gon is equal to 360.

Which table describes a relationship that can be represented in the form y = ax?
Answer:
The last one.
Step-by-step explanation:
The last table because y = 5x ( a = 5):
0 = 0*5
25 = 5*5
75 = 15*5
250 = 50 *5
Im not so sure about this. I need help making a proof that is 9 steps long. (See image)
Step-by-step explanation:
Not entirely sure, but I believe something like this:
∠1 + ∠2 = 180° since they are a linear pair;
Since ∠1 = ∠2, we can say:
∠1 + ∠1 = 180°
2(∠1) = 180°
∠1 = 90°
And since:
∠1 = ∠2
∠2 = 90°
So the angle between t and s is 90°;
An angle of 90° means t and s are perpendicular (⊥)
find the ratio a:b if given a+b=4a
Answer:
a:b = 1/3 = 0.333
Step-by-step explanation:
a+b=4a
a/b +b/b =4a/b
-3a/b = -1
a:b = 1/3 = 0.333
What is the slope and y-intercept of the equation 3x -y=3
Answer:
Slope = 3
Y Intercept = 3
Step-by-step explanation:
3x - y = 3
(subtract 3x from both sides - we have to get y by itself)
-y = -3x - 3
(divide by -1 from both side - we need to make y positive)
y = 3x + 3

Find the equation of the line with y-intercept 5 and slope 5/9
Answer:
y=5/9x+5
Step-by-step explanation:
The formula is y=mx+b with m being the slope and b being the y intercept so just plug in the values.
The equation of a straight line can be written by the equation y = mx + b, where m is the slope and b is the y-intercept.
Substitute in your values:
y = 5/9x + 5
Therefore the equation of your line with the information given would be:
y = 5/9x + 5

Find the slope containing the pair of points. (3,-3) (9,-1)
Answer:
1/3
Step-by-step explanation:
-3 - -1= -2
3-9 = -6
-2/-6 = 2/6 = 1/3
Answer: 1/3

Which is an equation for a line that passes through (0,-3) and is perpendicular to the graph of the line y=2x-3?
1. Y=-2x+3
2. Y= -2x-3
3. Y=-1/2x +3
4. Y=-1/2x-3
Answer:
the second one
Step-by-step explanation:
the last number of the equation (-3) is the y intercept, so it goes the the point (0,-3), also it has the opposite slope of y=2x-3
