PLZ HELP! FOR CROWN!

Answer: 6.73 × 10 -8

Step-by-step explanation:    

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.                                                                                      

Answer:

The time it will take will be ;

t = (2x -6)/(x^2-6x)

Where x is the amount of time

in minutes taken by the technician who is slower

Step-by-step explanation:

We want to write the time it would take to run the tests if the technicians work together.

Let the time taken by the first technician be x minutes

The time that would. taken by the second is 6 minutes less which is (x -6) minutes

So if they work together, how long will it take?

That would be ;

t = 1/x + 1/(x-6)

t = (x + x -6)/(x(x-6))

t = (2x -6)/(x^2 -6x)

The time it will take if they both work together is ;

t = (2x -6)/(x^2-6x)

where x minutes is the amount of time taken by the technician who is slower of the two

Answer: 40x2+21x−49

Step-by-step explanation:

17,400 - 3000 = 14,400

Let x be the number of months.

300x = 14,400

Divide by 300.

x = 48

12 months = 1 year

4 years is the answer.

Answer:

4 years

Step-by-step explanation:

Equation: 300x + 3000 = 17400

Subtract 3000 from both sides;

300x = 14400

Divide both sides by 300;

x = 48 months

48 months = 4 years

Answer:

20 + 5w

Step-by-step explanation:

20 + 5w

Were 20 is the amount she already has, and 5w is 5 times the unkown amount of weeks (w).

Pls consider marking me as Brainliest! It would mean a lot!

Answer: 5w + 20

Step-by-step explanation:

Because if she earns 5 every week that’s 5w and if she already had 20 that’s +20. So it’s 5w + 20 or 20+5w

The 'nth' term is a formula with 'n' in it which enables you to find any term of a sequence without having to go up from one term to the next. 'n' stands for the term number so to find the 50th term we would just substitute 50 in the formula in place of 'n'.

The slope is 0.75 as 3/4 = 0.75

Answer:

Step-by-step explanation:

Only the blue line has a positive slope.  So the new line is parallel to the blue line.

Clearly, the blue line goes through the point (0, 3) (this is the y-intercept).  Follow this blue line upward and to the right until it intersects the horizontal line at the top of the diagram.  We must estimate the x-value of this point of intersection.  A good approximation would be 5 1/3.

Now estimate the slope of the blue line.  Starting at (0, 3), we move 5 1/3 units to the right (this is the "change in x," or "run")  We end up at (5 1/3, 3).  

Now, from the horizontal line y = 3 upward to the horizontal line at the very top of the graph, is 5 units.  This is the "rise."

Thus, the approximate value of the slope here is

                              5               5             15

m = rise / run = ---------- = -------------- = ----------- = m

                          5 1/3           16/3             16

Answer:

-5

Step-by-step explanation:

The answer is -5 because we have -2 as x. The function is h(x)=3x+1. 3 times -2=-6. When we add 1 to the result, we have -5 as the answer. Hope it helps!

The value of h(−2) when h(x)=3x+1 is h(-2) = -5

From the question,

The given function is h(x)=3x+1

To determine the value of h(-2), we will put x = -2 and evaluate

From

h(x)=3x+1

h(-2) becomes

h(-2)=3(-2) + 1

h(-2) = (3× -2) + 1

h(-2) = (-6) + 1

h(-2) = -6 + 1

h(-2) = -5

Hence, the value of h(−2) when h(x)=3x+1 is h(-2) = -5

Answer:

[tex] h = 4.8 \: inches.[/tex]

Step-by-step explanation:

[tex]A= \frac{1}{2} h(a+b) \\ h(a + b) = 2A \\ h = \frac{2A}{(a+b)} = \frac{2 \times24 }{4 + 6} \\ h = \frac{48}{10} \\ h = 4.8 \: inches.[/tex]

Answer:

h=4.8

Given:

area=24 , a=4 , b=6

To find:

height

Step-by-step explanation:

A = [tex]\frac{1}{2}[/tex] × h(a+b)

24 = [tex]\frac{1}{2}[/tex] × h(4+6)

24 × 2 = h(10)

48 = 10h

48/10 = h

h=24/5

h=4.8

therefore, height of the trapezium is 4.8
