If a line of one billion people standing shoulder to shoulder stretches 346,439 miles long, what is the average shoulder width, in feet, of the people in the line?
Answers
Given a line of one billion people extending for 346,439 miles, the average shoulder width of a person in the line is approximately 1.83 feet.
Explanation:To find the average shoulder width of the people in the line, we need to convert the total miles into feet, since the result wanted is in feet. There are 5,280 feet in one mile. So the total length in feet would be 346,439 miles * 5,280 feet/mile = 1,829,029,920 feet. Now, if there are 1 billion people in this line, then the average width of a person's shoulders would be the total length divided by the total number of people. Hence, the average shoulder width = 1,829,029,920 feet / 1,000,000,000 people = approximately 1.83 feet.

Answers
The 1 is in the tenths decimal place
The 6 is in the hundredths decimal place
So put together 0.16 is spoken out as "16 hundredths" meaning we have the fraction 16/100
We simply write the numbers after the decimal "16" over the value 100
Another example is 0.37 = 37/100

The answer is 2.6 because with a - and + you subtract the two number and whichever is the highest number that is the sign that you put. In this case, the highest number is a +8.2 so your answer will be POSITIVE.
If the highest number was a negative for example, 5.6+ -8.2 then your answer will be -2.6

Dane is 10 times Brian's age. The difference in their age is 27, how old is Brian
Answers
Hope this helps!
Answer:
Brain is 3 years old.
Step-by-step explanation:
Let B represent Brain's age and D represent Dane's age.
We have been given that Dane is 10 times Brian's age. We can represent this information in an equation as:
[tex]D=10B...(1)[/tex]
We are also told that the difference in their age is 27. We can represent this information in an equation as:
[tex]D-B=27...(2)[/tex]
Upon substituting equation (1) i equation (2), we will get:
[tex]10B-B=27[/tex]
[tex]9B=27[/tex]
[tex]\frac{9B}{9}=\frac{27}{9}[/tex]
[tex]B=3[/tex]
Therefore, Brain is 3 years old.

The amount of substance left of a radioactive substance with half life of [tex]t_{ \frac{1}{2} }[/tex] after t years is given by
[tex]N(t)=N_0\left(\frac{1}{2} \right)^{ \frac{t}{t_{\frac{1}{2}} }[/tex]
Therefore, the number of years it will take for 18% of the original tritinum to remain is given by
[tex]18 \% = 100 \% \left(\frac{1}{2} \right)^{ \frac{t}{12.3}} \\ \\ \Rightarrow\left(\frac{1}{2} \right)^{ \frac{t}{12.3}} =0.18 \\ \\ \Rightarrow\frac{t}{12.3}\ln\left(\frac{1}{2} \right)=\ln0.18 \\ \\ \Rightarrow\frac{t}{12.3}= \frac{\ln0.18}{\ln\left(\frac{1}{2} \right)} = \frac{-1.715}{-0.6931} =2.474\\ \\ \Rightarrow t=2.474(12.3)=30.4[/tex]
Therefore, the number of years that the time could be read at night is 30.4 years.
Final answer:
You could read the time on a tritium-based watch in dark places for approximately 34.87 years before the tritium decays below 18% of its original amount, necessitating this calculation using first-order kinetics and the half-life of tritium (12.32 years).
Explanation:
To calculate how many years you could read the time at night with a watch containing tritium, we need to understand first-order kinetics and the half-life of tritium.
Tritium has a half-life of 12.32 years, meaning after 12.32 years, half of the original tritium remains.
The question specifies that a minimum of 18% of the original tritium is needed for readability in dark places.
To find the number of years you could read the time, we use the formula for first-order decay:
[tex]N = N_0(1/2)^{(t/T)[/tex],
where N is the final amount of substance left, N_0 is the initial amount of substance, t is the time in years, and T is the half-life (12.32 years in this case).
We rearrange the formula to solve for t:
t = T*log(N/N_0)/log(1/2).
Plugging in the values, assuming N/N_0 = 0.18 (18%), and T = 12.32 years, we get:
t = 12.32*log(0.18)/log(1/2) ≈ 34.87 years.
Therefore, you could read the time on a tritium-based watch in dark places for approximately 34.87 years before the tritium decays below the level necessary for visibility.

The formula for kinetic energy is shown. In the formula, m represents mass and v represents velocity. If mass is measured in grams and velocity is measured in centimeters per minute, what is the unit for kinetic energy
A) grams-centimeters per minute
B) grams-centimeters squared per minute
C) grams-centimeters per minute squared
D) grams-centimeters squared per minute squared
Answers
Answer D
E=mv²/2 ==> gram*cm²/min²
BUT it should be JOULES!!!
The unit for kinetic energy, when mass is in grams and velocity is in centimeters per minute, is D) grams-centimeters squared per minute squared.
The formula for kinetic energy is given by KE = 1/2 mv², where m represents mass and v represents velocity. To find the units of kinetic energy, we need to plug in the units of mass and velocity into the formula.
If m is measured in grams (g) and v is measured in centimeters per minute (cm/min), the units for velocity squared will be (cm/min)². Therefore:
KE = 1/2 (grams) (centimeters/minute)²
When we square velocity (cm/min), we get cm²/min². Thus, the units for kinetic energy become:
D) grams-centimeters squared per minute squared (g∙cm²/min²)

Step-by-step explanation:
Simplify the given expression (−3.5)(−3)(−6.4)
WE apply PEMDAS rule to simplify it
Lets start with parenthesis part
We multiply first two parenthesis
(−3.5)(−3)
Negative and negative becomes positive
(−3.5)(−3) is 10.5
Now we multiply it with -6.4. Positive times negative is negative.
[tex]10.5 \cdot (-6.4)= -67.2[/tex]
[tex](-3.5)(-3)(-6.4)=-67.2[/tex]

Use the variable t for the number of teeth in one row. Write an expression to determine the number of teeth in a sharks mouth.
Answers
The total number of teeth in a shark's mouth can theoretically be determined by multiplying the number of teeth in a single row by the total number of rows of teeth. The multiplication will be defined by the particular shark species.
Explanation:Assuming that we want to find out the total number of teeth in a shark's mouth and we know the number of teeth in one row (coded as t), we would need to multiply this number by the number of rows of teeth in the shark's mouth. For instance, if a shark has two rows of teeth, the total number of teeth would be 2t.
It is important to recognize that each species of shark might have a different number of rows of teeth, so without specifying the particular species, the exact total of teeth can't be computed but it would still be 't' times the number of rows. But in general, a Sand Tiger Sharks like Carcharias Taurus for example, can have around 3 to 7 rows of teeth.

A) (-8,5)
B) (8, -5)
C) (2, -3)
D) (-2, -3)
Answers
Answer:
New coordinates are (-2, -3)
Step-by-step explanation:
First we need the centre coordiates. In (x - a)² + ( y - b)² = r² , a is the x coordinate for the circle centre and b is the y coordinate for the circle centre, so this means the coordinate of the circle centre is:
(3 , -4)
If moving to the left 5 spaces, then 5 has to be subtracted from the x coordinate:
3 - 5 = -2
Now moving one up you add one to the y coordinate:
-4 + 1 = -3
So the new coordinates are (-2, -3)
