What is 0.007 divided by 0.498 to nearest tenth
Answers
Answer:
0.0
Step-by-step explanation:
To find 0.007 divided by 0.498, we can perform the following calculation:
0.007 / 0.498 ≈ 0.0141
Rounding this to the nearest tenth gives:
0.0141 ≈ 0.0
Therefore, the result, rounded to the nearest tenth, is 0.0.

5. The half-life of promethium is 17.4 years. How much of a 150-g sample will be present after 52.2 years?
150 g
18.75 g
25 g
8g
Answers
By half-life 18.75 gm sample of a 150-g sample will be present after 52.2 years.(option b)
What is half-life?
The time taken for half of reactions to completely done or the time at which the concentration of the reactant is reduced to half of its original value is called the half life period of the reaction. The half life is denoted by \(t_{1/2}\).
The half-life of promethium is 17.4 years.
\(N(t)= N_{0}( \frac{1}{2}) ^{t/t_{1/2} }\) ---------------------- (1)
N(t) = quantity of the substance remaining
N₀ = initial quantity of the substance
t = time elapsed
\(t_{1/2}\) = half life of the substance
Here given that N₀= 150 g
\(t_{1/2}\) = 17.4 years
t= 52.2 years
Then putting these values in equation (1) we get,
\(N(t)= 150( \frac{1}{2}) ^{52.2/17.4 }\)
N(t)= 150× (1/2)³
= 150×(1/8)
= 18.75
Hence, 18.75 gm sample of a 150-g sample will be present after 52.2 years.

2 and 3 are either subtraction or division property of equality
Answers
Given the equation 3t + 8 = 20 → 3t = 12 (by subtraction property of equality ) → t = 4 (by division property of equality ).
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
Given the equation,
3t + 8 = 20
If we subtract 8 from both sides by subtraction property of equality
3t + 8 - 8 = 20 - 8
3t = 12
If we divide 3 both sides by division property of equality
3t/3 = 12/3
t = 4
Hence "Given the equation 3t + 8 = 20 → 3t = 12 (by subtraction property of equality ) → t = 4 (by division property of equality )".

The length of a rectangle is 5 cm more than its width. If the perimeter is 58cm, calculate:
(a) Write an equation to show the perimeter of the rectangle ?
(b) calculate:
I.width
II.length
III. the area of the rectangle
Answers
The equation to show the perimeter of the rectangle is P = 2(2w + 5)
Writing an equation to show the perimeter of the rectangleFrom the question, we have the following parameters that can be used in our computation:
Length = 5 more than the width
Also, we have
Perimeter = 58
This means that
P = 2(w + 5 + w)
P = 2(2w + 5)
Calculating the dimensions and the areaIn (a), we have
P = 2(2w + 5)
This gives
2(2w + 5) = 58
So, we have
2w + 5 = 29
2w = 24
w = 12
Next, we have
l = 12 + 5
l = 17
Lastly, we have
Area = 17 * 12

The weights of certain machine components are normally distributed with a mean of 8.14 g and a standard deviation of 0.09 g. Find the two weights that separate the top 3% and the bottom 3%. These weights could serve as limits used to identify which components should be rejected.
Answers
The weights of certain machine components are normally distributed with a mean of 8.14 g
Mean = 8.14g
Standard Deviation = 0.09g
The weight that weights that separate the top is express as: P(X>x);
The expression for the normal distribution is express as;
\(P(Z=\frac{x-\mu}{\sigma})\)Since, it is given that distribution is 3%
so, P(Z) = 0.03
Substitute the value of Mean = 8.14g , P(Z) = 0.03and Standard Deviation = 0.09g
Now, for the bottom 3%; i.e. Z = 0
From the Z table P(0.03) = - 1.8808
\(\begin{gathered} P(Z=\frac{x-\mu}{\sigma}) \\ 1.8808=\frac{x-8.14}{0.09} \\ x=7.88 \end{gathered}\)Now, for the distribution that seperate down, is 3%
From the Z table P(0.03) = 1.8808 since, it seperate down
So, P(Z) = - 1.8808
\(\begin{gathered} P(Z=\frac{x-\mu}{\sigma}) \\ -1.8808=\frac{x-8.14}{0.09} \\ x=8.309 \end{gathered}\)Therefore, the limits that used to identify which components should rejected are 7.88 and 8.31

and (132 – 5)° =
Answers
Answer:
(19x - 1)° = 56°
(13x - 5)° = 34°
Step-by-step explanation:
Property of the interior angles of a triangle:
Sum of interior angles of a triangle is 180°.
Therefore, sum of angles of the given right triangle will be,
(19x - 1)° + (13x - 5)° + 90° = 180°
32x - 6 + 90 = 180
32x = 96
x = 3
(19x - 1)° = 19×3 - 1 = 56°
(13x - 5)° = 13×3 - 5 = 34°
Pablo used a total of 5 3/4 gallons of gas while driving his car. Each hour he was driving, he used 5/6 gallons of gas. What was the total number of hours he was driving? Write your ans
Answers
We know that he used 5/6 gallons of gas per hour of driving.
So, the total amount of gas he used is 5/6 * x.
We also know that he used a total of 5 3/4 gallons of gas.
So, we can set up the equation:
5/6 * x = 5 3/4
To solve for x, we can first convert 5 3/4 to an improper fraction:
5 3/4 = 23/4
Then, we can multiply both sides of the equation by the reciprocal of 5/6:
x = (5 3/4) / (5/6)
x = (23/4) / (5/6)
x = (23/4) * (6/5)
x = 27.6/4
x = 6.9
Therefore, Pablo was driving for a total of 6.9 hours.

What are the mean and standard deviation of
�
YY?
Answers
The mean score of a random student (YY) is 574.5. the standard deviation of the random student's score (YY) is 8.
How to answer the aforementioned questionGiven:
- Each correct question is worth 10 points.
- Every student receives an additional 555 bonus points.
Let's calculate the mean and standard deviation of YY:
Mean of YY:
The mean score, denoted as μY, can be calculated using the mean of XX (μX) and the scoring scheme:
μY = μX * 10 + 555
Substituting the value of μX from the given information:
μY = 1.95 * 10 + 555
μY = 19.5 + 555
μY = 574.5
Therefore, the mean score of a random student (YY) is 574.5.
Standard Deviation of YY:
The standard deviation of YY, denoted as σY, can be calculated using the standard deviation of XX (σX) and the scoring scheme:
σY = σX * 10
Substituting the value of σX from the given information:
σY = 0.8 * 10
σY = 8
Therefore, the standard deviation of the random student's score (YY) is 8.

Write the cruising altitude of Vincent’s plane in standard notation.
So, the answer will be =
\(3.2\times10^4=3.2\times10000=32000\)Part B
Write Felix’s skydiving altitude in standard notation.
So, the answer will be =
\(\text{1}.28\times10^5=1.28\times100000=128000\)Part C
What is the difference between the altitude of Vincent’s plane and Felix’s skydiving altitude?

Convert the difference of the altitudes from standard notation to scientific notation.
So, the answer will be =
\(96000=9.6\times10^4\)Now, We will solve the problem using scientific notation.
Part A
Transform Vincent’s plane’s altitude in scientific notation so that it has the same power of 10 as Felix’s altitude.
