If you start with 7,152 grams of a radioactive kind of lanthanum and the half-life is 93 minutes, how much will be left after 186 minutes
Answers
Answer:
1788 grams
Step-by-step explanation:
If you start with 7,152 grams of a radioactive kind of lanthanum and the half-life is 93 minutes, how much will be left after 186 minutes
We are to find Nt
The formula is given as:
Nt = No(1/2)^t/t½
Where
No = Initial amount = 7,152 grams
t = time elapsed = 186 minutes
t½ = Half life = 93 minutes
Nt = Amount of substance left
Nt = 7152(1/2)^186/93
= 1788 grams

The table of values below represents an inverse variation relationship. what is the value of x when y= "3.25"?
X l Y
2 l 13
4 l 6.5
A. X=84.5
B. X=8
C. X=5.3
D. X=21.1
Answers
Using the constant of proportionality, the value of when y is 3.25 is 0.5 from the inverse variation.
What is inverse variation relationship?An rise in one variable causes a decrease in the other and vice versa in a mathematical relationship between two variables known as inverse variation, also known as inverse proportionality or inverse relationship. The following equation represents inverse variation:
y = k/x
In this equation, "y" and "x" stand in for the two variables, and "k" is the variational constant. Throughout the connection, the constant of variation has a set value that never changes.
Using the data given;
y = kx
Let's find the value of k;
k = constant of proportionality
13 = k(2)
k = 13/2
k = 6.5
Using the value of k;
3.25 = 6.5x
x = 3.25 / 6.5
x = 0.5
NB: The options given are incorrect and if you will follow through the steps, you will understand the options are incorrect.

Three girls share R12000 in the ratio 2:3: 7. Calculate how much each girl
will get
Answers
2+3+7=12
12=12000
2?=
2×12000=24000÷12=2000.
R2000 for the first girl.
Step-by-step explanation:
3×12000=36000÷12=3000.
R3000 for the second girl.
7×12000=84000÷12=7000.
R7000 for the third girl.
Each of the three girls would get R2,000, R3,000 and R7,000 respectively.
Given the following data:
Total amount = R12,000.Ratio = 2:3:7Sum of ratio = [tex]2+3+7[/tex] = 12.To share R12,000 among three girls in the ratio of 2:3:7:
How to calculate a ratio.In this exercise, you're required to share the total amount of money among three girls in the ratio of 2:3:7. Thus, we would solve as follows:
For a ratio of 2:
[tex]Amount=\frac{2}{12} \times 12000\\\\Amount=\frac{24000}{12}[/tex]
Amount = R2,000.
For a ratio of 3:
[tex]Amount=\frac{3}{12} \times 12000\\\\Amount=\frac{36000}{12}[/tex]
Amount = R3,000.
For a ratio of 7:
[tex]Amount=\frac{7}{12} \times 12000\\\\Amount=\frac{84000}{12}[/tex]
Amount = R7,000.

the tasty Deli uses 6.5 lb of ham each day how many ounces of ham will be used in 3 w
eeks
Answers
There’s 16 ounces in a pound
135.5 • 16
Answer is 2,184 ounces of ham will be used in 3 weeks
Answer: 2184
Step-by-step explanation:
1lb = 16oz
6.5lb (16oz/1lb) = 104 oz
which means its 104 oz of ham uses in each day.
7 days in a week, then 3 weeks means 3 x 7 = 21 days
104oz in a day, 21 days (3 weeks) equals 21 x 104 = 2184 oz

find the mean of the set of data. round to the nearest 10th if necessary.
9.9, 10.8, 10.8, 6.2, 10.8, 7.2
Answers
Answer:
The mean of the data set is 9.3 rounded to the nearest tenth
Step-by-step explanation:
First you add them all together: 9.9 + 10.8 + 10.8 + 6.2 + 10.8 + 7.2 = 55.7
Then you divide it by how many numbers there are which is 6 in this situation:
55.7 ÷ 6 = 9.28333333333. but if we round it to the nearest tenth we get 9.3
So the answer is 9.3

Hope that helps!
Please mark brainliest
Answer:
x = 2
Step-by-step explanation:
The whole goal when solving problems like this is to get the x alone. So the first step would be to get the -3 over to the other side. To do this, you would add 3 to each side of the equation, so that the -3 on the left side cancels out.
-2x - 3 = -7
+3 +3
-2x = -4
The next thing you need to do is divide each side by -2. You would do this because right now, the equation reads "negative two times x equals negative four". When you divide a multiplication problem, it cancels out, so you are left with just the x.
-2x = -4
÷ -2 ÷ -2
x = 2
You now have the value of x.

Can I find the scale factor for a point with 2 different scale factors? (one for the x-axis and one for the y-axis)
Answers
Answer:
Yes
Step-by-step explanation:
Scale factor is the ratio of the length of one side of a point/figure to a similar side in another point or figure.
The scale factor can either be less than one(1) or greater than one(1) depending on the figure/ point you begin from when finding the scale factor.
Hence you can find the scale factor for a point with 2 different scale factors
