Element X is a radioactive isotope such that every 22 years, its mass decreases by half. Given that the initial mass of a sample of Element X is 1200 grams, how long would it be until the mass of the sample reached 800 grams, to the nearest tenth of a year?
Step-by-step explanation:
s1 = 1200 g
s2 = 1200×2^(-1/22)
s3 = 1200×2^(-2/22)
...
s23 (22 years later) = 1200×2^-22/22 ≈ 1200×2^-1 = 1200/2
sn = 1200×2^(-(n-1)/22)
what is the n, so that the result is 800 g ?
800 = 1200×2^(-(n-1)/22)
800/1200 = 2^(-(n-1)/22)
2/3 = 2^(-(n-1)/22)
log2(2/3) = -(n-1)/22
22×log2(2/3) = -(n - 1) = -n + 1
n = -22×log2(2/3) + 1 = 13.86917502...
since we stared counting with n=1 for the starting quantity, the number of years is truly 1 less than n (s2 is after 1 year, s3 after 2 years ...).
so, we know for n = 13.86917502..., that in fact
12.86917502... ≈ 12.9 years have passed until the mass of the sample reached 800g.

you have 120 red beads, loo white beads, and 45 blue beads. you want to use all the beads to make a bracelet that has red, white and blue beads on each. What is the greatest number of matching beads you can make?
Answer:
24 bracelets can be made from given beads.
● Explanation -To make similar bracelets using all the beads, we have to find the highest common factor of no of beads.Now, Factors of 72 => 1, 2, 3, 4, 6, 8 , 9, 12, 18, 24, 36, 72Factors of 192 => 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192Factors of 120 => 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120HCF => 24Observing this data, HCF of 72, 192 & 120 will be 24.Therefore, total 24 bracelets can be made from given beads.* Each bracelet will have 3 red, 8 blue and 5 white beads.

a cone has a volume of 150.72 cubic millimeters and a height of 9 millimeters what is the radius
The volume of a cone is the amount of space in the cone
The radius of the cone is 4.00 millimeters
How to determine the radiusThe given parameters are:
Volume = 150.72 cubic mL
Height = 9 mL
The volume of a cone is calculated as:
[tex]V = \frac 13 \pi r^2h[/tex]
So, we have:
[tex]150.72 = \frac 13 \pi * r^2 * 9[/tex]
Divide
[tex]150.72 = \pi * r^2 * 3[/tex]
Divide both sides by 3
[tex]50.24 = \pi * r^2[/tex]
Rewrite the equation
[tex]50.24 = \frac{22}{7} * r^2[/tex]
Solve for r^2
[tex]r^2 = 50.24 * \frac{7}{22}[/tex]
Solve for r
[tex]r = 4.00[/tex]
Hence, the radius of the cone is 4.00 millimeters

Answer:
4 inches
Step-by-step explanation:
Every 25 miles the map shows 1 inch
100 miles is equal to 4 x 25 miles, thus 100 miles on the map will be 4 times longer than 1 inch => 4 inches
Select the correct answer. Brianna begins the construction of square EGFH inscribed in circle C by drawing GH, a diameter of the circle that is also a diagonal of the square. Next, she plans to use a compass to construct a perpendicular bisector of GH and mark points E and F at the intersections of the arcs she used to find the bisector. What error, if any, is Brianna making? A. She is not making any errors. B. She should name the diameter she first drew EG and name the new segment FH. C. She should use the compass to find the perpendicular bisector of GC instead of GH. D. She should define points E and F as where the perpendicular bisector of GH intersects the circle. Reset Next
Answer:
B. "She should name the diameter she first drew EG and name the new segment FH."

What is the quotient ? StartFraction 7 Superscript negative 6 Over 7 squared EndFraction StartFraction 1 Over 7 Superscript 8 EndFraction StartFraction 1 Over 7 cubed EndFraction 73 78.
The quotient of the start fraction 7 superscript 7 negative 6 over 7 squared end fractions is,
[tex]\dfrac{1}{7^8}[/tex]
What is the quotient?Quotient is the resultant number which is obtained by dividing a number with another. Let a number a is divided by number b. Then the quotient of these two number will be,
[tex]q=\dfrac{a}{b}[/tex]
Here, (a, b) are the real numbers.
The number given in the problem is,
[tex]\dfrac{7^{-6}}{7^2}[/tex]
Let the quotient of these number is n. Therefore,
[tex]n=\dfrac{7^{-6}}{7^2}\\[/tex]
Now if the power of numerator is negative, then it can be written in denominator with positive power of the same number. Therefore, the above equation written as,
[tex]n=\dfrac{1}{7^2\times7^{6}}\\n=\dfrac{1}{7^{2+6}}\\n=\dfrac{1}{7^8}[/tex]

What is an equation of the line that passes through the points (8,0) and (3,-5)?
Answer:
y = x - 8
Step-by-step explanation:
You want an equation for the line through the points (8, 0) and (3, -5).
SlopeThe slope of the line can be found using the formula ...
m = (y2 -y1)/(x2 -x1)
m = (-5 -0)/(3 -8) = -5/-5 = 1
InterceptThe y-intercept can be found from the equation ...
b = y1 -m(x1)
b = 0 -1(8) = -8
Slope-intercept equationThe slope-intercept equation of the line is ...
y = mx +b
y = 1·x +(-8)
y = x -8 . . . . . an equation for the line

Which ratio best defines relative frequency? Number of nonfavorable outcomes:Number of possible outcomes Number of possible outcomes:Number of nonfavorable outcomes Total number of times an experiment is performed:Number of times an event occurs Number of times an event occurs:Total number of times an experiment is performed.
The ratio which best defines relative frequency is, number of times an event occurs:Total number of times an experiment is performed.
What is relative frequency?Relative frequency of a event is the measure of something happens relative to the total outcomes of that event.
The relative frequency can be given as,
[tex]f_r=\dfrac{f}{n}[/tex]
Here, (f) is the frequency of the number of times data occurred in an event and (n) is the total number of outcomes.
The relative frequency can also be defined as, it is the ratio of subgroup frequency to the total frequency of any event.
Now, the ratio has to be find out which best defines relative frequency. Lets check options,
Number of non-favorable outcomes:Number of possible outcomes-Here, the non-favorable outcomes is asked but for the relative frequency the favorable outcomes is considered. Number of possible outcomes:Number of non-favorable outcomes-The number of total outcomes is considered for a relative frequency. Total number of times an experiment is performed:Number of times an event occurs-This ratio is inverse as the ratio of relative frequency.Number of times an event occurs:Total number of times an experiment is performed-This is the correct option, as it justify the definition of the relative frequency.Hence, the ratio which best defines relative frequency is, number of times an event occurs:Total number of times an experiment is performed.

Slope of (7, -2) and (2, -6)
Answer:
[tex]\boxed{\sf{m=\frac{4}{5}}}[/tex]
Step-by-step explanation:
In order to solve this problem, we will use the slope.
Slope:
[tex]\sf\dfrac{Y_2-Y_1}{x_2-x_1}=\dfrac{rise}{run}[/tex]
y2=(-6)
y1=(-2)
x2=2
x1=7

m=4/5
Therefore, the slope is 4/5.
