Final answer:
When multiplying 0.07 by 1.22, the product is 0.0854. This result is calculated by first multiplying the numbers as whole numbers and then placing the decimal point so that the total number of decimal places in the product matches the sum of the decimal places in the factors.
Explanation:
To calculate the product of 0.07 and 1.22, you follow the standard multiplication procedure for decimals:Multiply as if the numbers were whole numbers; ignore the decimal points for a moment.Count the total number of decimal places in both of the numbers you're multiplying. In 0.07, there are two decimal places. In 1.22, there are two decimal places as well.Add the number of decimal places together. In this case, 2 (from 0.07) plus 2 (from 1.22) equals 4 decimal places in total.Perform the multiplication without considering the decimal, which gives you 7 * 122 = 854.Place the decimal point in the answer (854) so that there are 4 decimal places, giving you 0.0854.Therefore, 0.07 multiplied by 1.22 equals 0.0854.
Final answer:
When multiplying 0.07 by 1.22, we first ignore the decimals and multiply 7 by 122 to get 854, and then we place the decimal point so the result has the same number of decimal places as the sum of the factors, resulting in 0.0854.
Explanation:
To find the product of two decimal numbers, you multiply them just as you would with whole numbers, taking care to place the decimal point in the correct position in the final answer. For the multiplication of 0.07 by 1.22, you perform the multiplication ignoring the decimals first, and then place the decimal in the final answer so that the total number of decimal places equals the sum of the decimal places in the factors.
Multiplying 7 by 122 equals 854. Since 0.07 has two decimal places and 1.22 has two decimal places, the product must have four decimal places. Therefore, the correct placement of the decimal point in 854 would be after four digits from the right, which gives us a final answer of 0.0854.

Kathy runs a 26.2- mile marathon at an average pace of 6.2 minutes per mile how long will it take her to finish
Kathy will complete the 26.2-mile marathon in approximately 2 hours and 42 minutes by multiplying the marathon distance by her average pace and converting the result from minutes to hours and minutes.
To calculate the time it will take for Kathy to finish a 26.2-mile marathon at an average pace of 6.2 minutes per mile, we simply multiply the distance of the marathon by her average pace per mile. This is a basic mathematics problem involving multiplication to determine the total time.
Here is the calculation:
Total marathon distance = 26.2 miles
Average pace = 6.2 minutes per mile
Total time = Total marathon distance x Average pace
Total time = 26.2 miles x 6.2 minutes per mile = 162.44 minutes
To convert minutes into hours and minutes, we know that there are 60 minutes in an hour. Therefore:
Hours = Total time / 60
Hours = 162.44 minutes / 60 ≈ 2.707 hours
Since we want hours and the remaining minutes, we can take the decimal part and multiply it by 60:
Remaining minutes = 0.707 x 60 ≈ 42.42 minutes
Hence, Kathy will complete the marathon in approximately 2 hours and 42 minutes.

What is the thickness t of the thin film of diamond? express your answer in nanometers using three significant figures?
The thickness of a thin film of diamond can be calculated using the formula t = (m * λ) / (2 * n), where m is the number of fringes, λ is the wavelength of light used, and n is the refractive index of diamond.
Explanation:The thickness of a thin film of diamond can be determined using the formula:
t = (m * λ) / (2 * n)
where t is the thickness, m is the number of fringes, λ is the wavelength of light used, and n is the refractive index of diamond.
In this case, the number of fringes is given as 14 per centimeter, which can be converted to 140 per meter. The wavelength of the light used is not provided, so we cannot determine the thickness without that information.

There are 10 less trumpet and saxophone players number of saxophone players three times the number of trumpet players how many trumpet players are there?
There are 3 trumpet players.
We have,
Let's assume the number of trumpet players is represented by "x".
According to the given information, the number of saxophone players is three times the number of trumpet players, so the number of saxophone players would be 3x.
It is also stated that there are 10 less saxophone players than the total number of trumpet and saxophone players.
So, the number of saxophone players would be (x + 3x) - 10, which simplifies to 4x - 10.
Since the number of saxophone players is equal to 4x - 10, we can set up an expression to solve for x:
4x - 10 = x
To isolate x, subtract x from both sides of the expression:
4x - x - 10 = x - x
This simplifies to:
3x - 10 = 0
Next, add 10 to both sides:
3x - 10 + 10 = 0 + 10
This yields:
3x = 10
Finally, divide both sides by 3:
(3x) / 3 = 10 / 3
The solution is:
x = 10/3 or approximately 3.33
Therefore,
There are approximately 3.33 trumpet players.
Since you cannot have a fraction of a player, we can conclude that there are 3 trumpet players.

what is the 13th term in the arithmetic sequence described by this explicit formula an=84+(n-1)(-6)
Answer:
12
Step-by-step explanation:
The formula given is [tex]a_n=84+(n-1)(-6)[/tex]
Where [tex]a_n[/tex] gives the nth term
Since we want 13th term, we can say we want [tex]a_{13}[/tex] and we plug in 13 in [tex]n[/tex] into the formula. So we get:
[tex]a_n=84+(n-1)(-6)\\a_{13}=84+(13-1)(-6)\\a_{13}=84+(12)(-6)\\a_{13}=84-72\\a_{13}=12[/tex]

At noon, ship A is 170 km west of ship B. Ship A is sailing east at 35 km/h and ship B is sailing north at 20 km/h. How fast is the distance between the ships changing at 4:00 PM?
The distance between the ships is changing at a rate of 39 km/hr at 4:00 PM. This is calculated using differentiation of the Pythagorean theorem relating distances between the ships.
Explanation:This is a typical
related rates problem
in calculus. Before we start, let's mark the distance between ship A and ship B as C, the distance that A traveled as X (X=35 km/hr*4 hr = 140 km), and the distance B traveled as Y (Y=20 km/hr*4 hr = 80 km). Note that X, Y, and C form a right triangle. By using the Pythagorean theorem, we get C²=X²+Y², which we can differentiate with respect to time (t) to obtain, 2C * dC/dt = 2X * dX/dt + 2Y * dY/dt. As we're solving for dC/dt (rate of change of the distance between the two ships), we get dC/dt = (X * dX/dt + Y * dY/dt) / C. Plugging in the known values (X=140 km, Y=80 km, dX/dt=35 km/hr, dY/dt=20 km/hr, and C=170 km, as it hasn't changed since they started), we get dC/dt = (140*35 + 80*20) / 170 = 39 km/hr. So, the distance between the ships is changing at a rate of 39 km/hr at 4:00 PM.

It is claimed that in a bushel of peaches, less than 10% are defective. a sample of 400 peaches is examined and 50 are found to be defective. what is the critical value for α = 0.025?
Final answer:
To find the critical value for α = 0.025 in a one-tailed test, we look at the standard normal distribution tables; the critical value is approximately -1.96.
Explanation:
The question pertains to hypothesis testing in the context of proportion analysis. To determine the critical value for a significance level α = 0.025 in a one-tailed test about a proportion, we use the standard normal distribution (Z-distribution). Given that the sample size is large (n=400), it is appropriate to use a Z-test for this calculation. The critical value corresponds to the Z-score that has 0.025 of the distribution's area to its right (since we are checking for 'less than 10% defective').
Referring to standard normal (Z) distribution tables or using statistical software, we can find that the critical value for α = 0.025 for a one-tailed test is approximately -1.96. This is the Z-score such that the area under the normal curve to the right of this value is 0.025. If the calculated Z-score obtained from the sample proportion is less than -1.96, we would reject the null hypothesis that the proportion of defective peaches is less than 10%.
