Hair grows at an average speed of 3x10^-9 m/s. how long does it take to get to 10cm? note: 1 yr = 3.156 × 10^7 s.
Answers
Given that the growth speed of hair is 3 x 10^-9 m/s.
We have to determine how long would it take to get to 10 cm.
It is known that t = d/s.
Here, d = 10 cm = 0.1 m and s = 3 x 10^-9 m/s. So,
\(\begin{gathered} t=\frac{0.1}{3\times10^{-9}} \\ t=\frac{0.1\times10^9}{3} \\ t=\frac{10}{3}\times10^8 \\ t=3.33\times10^8\text{ seconds} \end{gathered}\)We know that 1 yr = 3.156 × 10^7 s. So, the time taken (in years) is:
\(\frac{3.33\times10^8}{3.156\times10^7}=1.055\times10=10.55\text{ years}\)Thus, it will take 10.55 years to grow the hairs to 10 cm.

Answer:
<a=138°
<b=42°
<c=138°
<d=138°
<e=42°
<f=42°
Step-by-step explanation:
<a is supplementary with the 42° angle:
<a=180°-42°=138°
<b and the 42° are vertical angles, so:
<b=42°
<c and <a are also vertical angles so:
<c=<a=138°
<d and <a are corresponding angles, so:
<d=<a=138°
<e and <b are corresponding angles, so:
<e=<b=42°
<f and the 42° angle are corresponding angles, so:
<f=42°
<g and <c are corresponding angles, so:
<g=<c=138°

If Denny (random name) left to another country and he left the Tuesday of this week (June 20) and he left for a month, what day would he be back on? I though July 18 but I’m not sure. Pls help?
Answers
Answer:
Step-by-step explanation:
Well, since the length of a month can vary in the number of days, this answer can also vary.
For example, February is only 28 days long, while December is 31 days long.
That being said, the average length of all 12 months is 30.436875 days, so if Denny left to another country on June 20th, he would most likely be back July 19th of July 20th.

Suppose that a study of elementary school students reports that the mean age at which children begin reading is 5.4 years with a standard deviation of 0.8 years.
Step 2 of 2: If a sampling distribution is created using samples of the ages at which 38 children begin reading, what would be the standard deviation of the sampling distribution of sample means? Round to two decimal places, if necessary.
Answers
Answer:
Step-by-step explanation:
The standard deviation of the sampling distribution of sample means is given by the formula:
standard deviation = population standard deviation / sqrt(sample size)
Here, the population standard deviation is 0.8 years, and the sample size is 38. Substituting these values into the formula, we get:
standard deviation = 0.8 / sqrt(38)
standard deviation ≈ 0.13
Rounding to two decimal places, the standard deviation of the sampling distribution of sample means is approximately 0.13 years.

In circle O, secants ADB and AEC are drawn from external point A
such that points D, B, E, and C are on circle O. If AD = 8, AE = 6,
and EC is 12 more than BD, the length of BD is
(1) 6
(2) 22
(3) 36
(4) 48
Answers
The length of BD is 22.
In the given scenario, let's consider the following information.
AD = 8
AE = 6
EC is 12 more than BD.
To find the length of BD, we can utilize the Intercepted Arcs Theorem, which states that when two secants intersect outside a circle, the measure of an intercepted arc formed by those secants is equal to half the difference of the measures of the intercepted angles.
From the given information, we know that AD = 8 and AE = 6.
Since these are the lengths of the secants, we can use them to calculate the intercepted arcs.
First, let's find the intercepted arc corresponding to AD:
Intercepted Arc ADB = 2 \(\times\) AD = 2 \(\times\) 8 = 16
Similarly, we can find the intercepted arc corresponding to AE:
Intercepted Arc AEC = 2 \(\times\) AE = 2 \(\times\) 6 = 12
Now, we know that EC is 12 more than BD.
Let's assume the length of BD as x.
BD + 12 = EC
Now, let's consider the intercepted arcs theorem:
Intercepted Arc ADB - Intercepted Arc AEC = Intercepted Angle B - Intercepted Angle C
16 - 12 = Angle B - Angle C
4 = Angle B - Angle C.
Since Angle B and Angle C are vertical angles, they are congruent:
Angle B = Angle C.
Therefore, we can say:
4 = Angle B - Angle B
4 = 0
However, we have reached an inconsistency here.
The equation does not hold true, indicating that the given information is not consistent or there may be an error in the problem statement.
As a result, we cannot determine the length of BD based on the given information.

So,
\(r=-64i=64\angle270\)So,

Multiply the following and express the results in scientific notation
(4 x 10^11) (8x 10^6)
Answers
Step-by-step explanation:
To multiply two numbers in scientific notation, you multiply their coefficients and add their exponents. Applying this rule, we get:
(4 x 10^11) (8 x 10^6) = (4 x 8) x (10^11 x 10^6) = 32 x 10^17
However, this result is not yet in scientific notation because the coefficient 32 is not between 1 and 10. To put it in scientific notation, we need to divide the coefficient by 10 and increase the exponent by 1. This gives:
32 x 10^17 = 3.2 x 10^18
Therefore, the product of (4 x 10^11) and (8 x 10^6) expressed in scientific notation is 3.2 x 10^18.

A mixture of 5% disinfectant solution is to be made from 8% and 4% disinfectant solutions. How much of each solution should be used if 28 gallons of 5% solution are needed?
Answers
Answer
You need 7 gallons of 8% solution and 21 gallons of 4% solution
Step-by-step explanation
Data
• The concentration of solution 1: 8%
,• The concentration of solution 2: 4%
Variables
• Amount of solution 1: x gallons
,• Amount of solution 2: y gallons
The amount of disinfectant in solution 1 is 8% of the x gallons.
The amount of disinfectant in solution 2 is 4% of the y gallons.
The amount of disinfectant in the final mixture is 5% of the 28 gallons.
The final mixture is made by adding solution 1 to solution 2, that is,
\(\begin{gathered} x+y=28\text{ \lparen total solution\rparen - eq. 1 } \\ x\cdot8\text{ \%}+y\cdot4\text{ \%}=28\cdot5\text{ \% \lparen amount of disinfectant\rparen} \\ 0.08x+0.04y=1.4\text{ \lparen changing percentage to decimals\rparen - eq. 2} \end{gathered}\)Isolating x from equation 1:
\(x=28-y\text{ \lparen eq. 3\rparen}\)Substituting equation 3 into equation 2 and solving for y:
\(\begin{gathered} 0.08(28-y)+0.04y=1.4 \\ 0.08(28)-0.08y+0.04y=1.4 \\ 2.24-0.04y=1.4 \\ -0.04y=1.4-2.24 \\ y=\frac{-0.84}{-0.04} \\ y=21 \end{gathered}\)Substituting y = 21 into equation 3:
\(\begin{gathered} x=28-21 \\ x=7 \end{gathered}\)
