Answer:
How is genetic information passed from parents to offspring in humans?
But when people talk about genes being passed on, they generally don't mean genes being passed on from cell to cell during cell division. Instead, they usually mean genes being passed on from parents to children. This is known as "heredity" or "inherited genes."

Answer:
D. [tex]-360\,\frac{km}{h}[/tex]
Step-by-step explanation:
Physically speaking, average acceleration ([tex]\bar a[/tex]), measured in kilometers per square hour, is defined by following formula:
[tex]\bar a = \frac{v_{f}-v_{o}}{t_{f}-t_{o}}[/tex] (1)
Where:
[tex]v_{o}[/tex], [tex]v_{f}[/tex] - Initial and final speed, measured in kilometers per hour.
[tex]t_{o}[/tex], [tex]t_{f}[/tex] - Initial and final instant, measured in hours.
The initial and final instants are, respectively:
[tex]t_{o} = 5\,min\times \frac{1\,h}{60\,min}[/tex]
[tex]t_{o} = 0.083\,h[/tex]
[tex]t_{f} = 9\,min \times \frac{1\,h}{60\,min}[/tex]
[tex]t_{f} = 0.15\,h[/tex]
If we know that [tex]t_{o} = 0.083\,h[/tex], [tex]v_{o} = 60\,\frac{km}{h}[/tex], [tex]t_{f} = 0.15\,h[/tex] and [tex]v_{f} = 36\,\frac{km}{h}[/tex], then the average acceleration of Kelly is:
[tex]\bar a = \frac{36\,\frac{km}{h}-60\,\frac{km}{h}}{0.15\,h-0.083\,h}[/tex]
[tex]\bar a = -358.209\,\frac{km}{h^{2}}[/tex]

What is the answer to this any body know it??????????
Answer:
2n+10
Step-by-step explanation:
you just distribute the -2 and you get -14+2n+4 and then add and you'll get 2n+10
if you are solving for the variable n then you would want your equation like this 2n+10=0
next you would put the 10 on the other side of the equation and have 2n=-10
finally you would divide by 2 and get n=-5

Jackson’s car was making a rumbling noise for two weeks. He decided to take it to the mechanic to get it checked out. To diagnose the problem, the mechanic tells Jackson that he charges a flat fee of $60 and $35 for each hour he spends trying to identify the problem.
A. Write a linear equation in y = mx+b form to represent the cost of getting Jackson’s car diagnosed.
B. Identify the slope and y-intercept, and what they mean in the context of the story.
C. Does this situation represent a proportional relationship? Why or why not?
Answer:
y=35x+60
slope-35 y intercept-60
proportional relationship
Step-by-step explanation:
Answer:
Step-by-step explanation:
y = 35x + 60
Slobe 35
y-intercept 60
The y-intercept is the start cost and the slope is how much it will go up per hour.
It is proportional because it is going up by 35 every hour

The time required to complete a job varies inversely as the number of people working. It took 4 hours for 7 electricians to wire a building. How long would it have taken 3 electricians?
A. 1 hour 43 minutes
B. 5 hours 15 minutes
C. 7 hours 30 minutes
D. 9 hours and 20 minutes
Answer:
9 hours and 20 minutes: b
Step-by-step explanation:
4*60=240
7x240=1680
1680/3=560
560= 9 h 20 m
The time required when 3 electricians are working is 9 hours and 20 minutes.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
The time required to complete the job varies inversely with the number of people working.
This means that if the number of people working decreases, the time required to complete the job will increase.
We can use the formula for inverse variation to solve the problem:
t = k/n
where t is the time required to complete the job, n is the number of people working, and k is a constant of proportionality.
We can find k by plugging in the given values:
4 = k/7
k = 28
Now we can use the formula to find the time required when 3 electricians are working:
t = 28/3
t ≈ 9.33 hours
Converting this to hours and minutes, we get:
t ≈ 9 hours and 20 minutes
Thus,
The time required when 3 electricians are working is 9 hours and 20 minutes.

Answer:
-3
Step-by-step explanation:
1 × -3 = -3
-3 × -3 = 9
9 × -3 = -27
-27 × -3 = 81
81 × -3 = -243
The pattern is that each number is multiplied by -3, and 1 × -3 = -3.
A carton of milkshake comped with 25% extra free. A normal size carton is 320ml calculate the volume of milkshake in the larger carton. find 25% of 320
Step 1: Our output value is 350.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$350=100\%$.
Step 4: Similarly, $x=25\%$.
Step 5: This results in a pair of simple equations:
$350=100\%(1)$.
$x=25\%(2)$.
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{350}{x}=\frac{100\%}{25\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{350}=\frac{25}{100}$
$\⇒x=87.5$
Therefore, $25\%$ of $350$ is $87.5$
Find the dimension of a rectangle whose with is 6 miles less than its length and whose area is 72 square tiles
Answer:
Length = 12
Width = 6
Step-by-step explanation:
Width = 6 miles less than length;
L = L
W = L - 6
Area = 72 ft²
Area = Length * width
Area = (L * L-6)
Area = L² - 6L
-
L² - 6L = 72
L² - 6L - 72 = 0
L² - 12L + 6L - 72 = 0
L(L - 12) +6(L - 12) = 0
L = 12 or L = - 6
L cannot be negative
Width = L - 6
Width = 12 - 6 = 6

Which table represents a linear function?
at a summer camp there is one counselor for every 5 campers.
Answer:
Then if there were 10 campers, there would be 5 counselors
Step-by-step explanation:
For every five campers, there is one counselor. Divide the number of campers by 2 two find how many counselors there are.
Express $0.\overline{5}$ as a common fraction in lowest terms.
=======================================================
Explanation:
[tex]0.\overline{5}[/tex] means that the 5's go on forever because of that horizontal bar over top. So we can write it as [tex]0.\overline{5} = 0.55555\ldots[/tex]
The three dots indicate it goes on forever following that pattern.
Let
x = 0.55555....
Multiply both sides by 10 to move the decimal point 1 spot to the right
10x = 5.55555....
Notice how both x and 10x involve a decimal number such that we have a string of 5's going on forever. If we subtract the two equations, then 10x-x becomes 9x, while the (5.55555....) - (0.55555....) simplifies to 5. The decimal portions cancel out when we subtract since they line up perfectly. We're effectively subtracting 5-0 when we cross off the decimal portions.
After those subtractions, we're left with 9x = 5 which solves to x = 5/9 when you divide both sides by 9.
Use of a calculator should show that 5/9 = 0.555555.... to help confirm the answer. Your calculator may show the last digit to be a 6 instead of a 5, but this is due to rounding. Ideally you should have a string of infinitely many 5's, but the calculator can only how so many digits.

What are the roots of the equation?
10x2 - 6x + 4 = -3x
Answer:
(3 +/- i*sqrt(151) / 20 (no real solutions)
Step-by-step explanation:
10x^2 - 6x + 4 = -3x
Add 3x to both sides
10x^2 - 6x + 4 + 3x = -3x + 3x
10x^2 - 6x + 4 + 3x = 0
Add like terms
10x^2 - 3x + 4 = 0
We have to use quadratic formula to find the answers
For this equation, a = 10, b = -3 and c = 4
Note: +/- is plus or minus
Quadratic formula:
x = (-b +/- sqrt(b^2 - 4ac)) / 2a
x = (-(-3) +/- sqrt(-3^2 - 4(10)(4))) / 2(10)
x = (3 +/- sqrt(9 - 160)) / 20
x = (3 +/- sqrt(-151) / 20
x = (3 +/- i*sqrt(151) / 20
if there's a "-" sign inside a square root, it will give you an imaginary number.
Example:
-sqrt(9) = -3
sqrt(-9) = 3i (first you will ignore the "- " sign, then square the number. After finding the square root, take that '-' sign and turn it to an "i")
So for sqrt(-151), 151 is not a perfect square, so you will get a decimal number. Leave it as it is:
sqrt(151). We can't forget about the "-". Turn the minus into a sign.
It will be i*sqrt(151)
Imaginary numbers can't be simplified, so this is the answer.
(3 +/- i*sqrt(151) / 20
