Strontium-90 has a half-life of about 28 years. Which equation will solve the problem of how many grams of a 40 g sample
will remain after 84 years?
Oy = }(40)
y = {(40)
Oy = 40(1)
y = 40()
84
Answer:a0 = 40 mg
a1 = 20 mg after 28 years
a2 = 10 mg after another 28 years
Step-by-step explanation:Set this up as
10 = 40 (1/2)t/28
and solve for t in years.
10/40 = (1/2)t/28
log(0.25) = (t/28) log(0.5)
t = 28 log(0.25) / log(0.5) years = 56 years
Answer:
40 mg
Step-by-step explanation:
10 = 40 (1/2)t/28 and solve for t in years. 10/40 = (1/2)t/28 log(0.25) = (t/28) log(0.5) t = 28 log(0.25) / log(0.5) years = 56 years
through: (3, - 3); slope = 2/3
Answer:
y=2/3x - 5
Step-by-step explanation:
Since we have the slope and a point, we can make an equation in point intercept form (y=mc+b) by using the point slope form formula (y-y1)=m(x-x1), where (x1,y1) is the point you plug in.
(y-y1)=m(x-x1)
m=2/3
y1=-3
x1=3
y- -3=2/3(x-3)
y+3=2/3(x-3)
Distribute 2/3 with (x-3) by multiplying
y+3=2/3x - 2
Subtract 3 from both sides
y=2/3x - 5

Find the median of 12,15,6,32
Answer:
13.5
Step-by-step explanation:
Put the numbers in order from smallest to largest
6,12,15,32
Find the middle
6,12 ,15,32
The middle is between 12 and 15 so average them
(12+15)/2 = 27/2 = 13.5
Answer:
13.5
Step-by-step explanation:
The "Median" is the middle number in a data set
To do this...
Step 1. Order the numbers from smallest to largest
Answer: 6, 12, 15 & 32
Step 2. Find the median (middle number)
Answer: Since the median is between 12 and 15,
we'll need to add both numbers and divided the sum
in half
12 + 15 = 27/2 = 13.5
therefore. the median of the data set is 13.5
Find the equation of the line: with an intercept of 4 and a y intercept of -1.5

Adapted from Tess-India (Elementary Mathematics)
Explain step by step, how you arrived at your answer to determine the area
and perimeter of the figure in the grid paper.
The perimeter of a shape is the summation of the visible lengths of the figure. The area; however, is the product of the length and the width of the figure
The perimeter of the figure is 58 units and the area of the figure is 130 unit square
Your question is not properly formatted and the diagram required to solve the question is missing. I've included the appropriate diagram.
Having said that, the perimeter is:
Perimeter = sum of all sides
[tex]Perimeter = 7 + 8 + 5 + 8 + 3 + 6 + 3 + 5 + 7 + 6[/tex]
[tex]Perimeter = 58[/tex]
To calculate the area, we use a different approach.
First, we split the figure into 3, we then calculate the area of each sub-figure, and then we add up the calculated areas.
From left to right, we have:
Rectangle 1
[tex]Length = 7\\Width = 6[/tex]
Rectangle 2
[tex]Length = 5\\Width = 6+8 = 14[/tex]
Rectangle 3
[tex]Length = 3\\Width = 6[/tex]
The area of a rectangle is:
[tex]Area = Length * Width[/tex]
So, the area of the figure is:
[tex]Area = 7 * 6 + 5 * 14 + 3 * 6[/tex]
[tex]Area = 130[/tex]

What the answer for this question
Answer:
I think the Correct answer is no A.
the length of a building is 720 in. Use dimensional analysis to convert this quantity to yards.
Answer:
20 yards
Step-by-step explanation:
First, we have to know how to get from inches to yards. 12 inches = 1 foot, and 3 feet = 1 yard.
Next, we have
[tex]\frac{720 in}{1}[/tex]
as a given. We want to multiply this by our conversions to get the end amount in yards.
We can first multiply our expression by 12 inches = 1 foot. To do this, we can set one number as the divisor and one as the dividend, e.g. 12 inches / 1 foot. However, to figure out which number should be the numerator/denominator, we first must examine our original expression. We want to multiply it by a value that cancels something out in conversion. To do this, we can have the same unit of something in the numerator in one and the denominator in the other in terms of what we're multiplying. Here, we can see that [tex]\frac{720 in}{1}[/tex] has inches on the top, so we want inches on the bottom in 12 inches = 1 foot. Therefore, we have
[tex]\frac{720 in}{1} * \frac{1 foot}{12 inches}[/tex]
= [tex]\frac{720feet}{12}[/tex]
= 60 feet
= [tex]\frac{60 feet }{1}[/tex]
We have feet as the numerator, so we want feet in the denominator in what we're multiplying this by. In 3 feet = 1 yard, we can multiply this to get
[tex]\frac{60 feet }{1} * \frac{1 yard}{3 feet} \\= \frac{60 yards}{3}[/tex]
= 20 yards
