the area of a trapezium is given by the formula A=1/2h(a+b), where h is the height and a and b are the measures of the two bases. what is the height of a trapezoid with an area of 24 square inches if the two bases measure 4 inches and 6 inches?
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

Two laboratory technicians are running product quality tests. One technician takes 6 minutes less than the
other. What equation would give the amount of time, t, it would take to run the tests if the technicians work
together to split the work on the different tests?
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
Josiah cell phone plan allows a number of minutes of air time for $20 a month each minute costs 0.02 $ how many minutes of air time is he allowed?
Given parameters:
Cost of cell phone plan per minute = 0.02$/min
Amount in a month = $20
Unknown:
Number of minutes allowed per month?
Solution:
The number of minutes = [tex]\frac{amount per month}{rate per call}[/tex]
Input the parameters and solve;
= [tex]\frac{20}{0.02}[/tex]
= 1000min
The number of minutes allowed per month is 1000min

What is the value of h(−2) when h(x)=3x+1?
Enter your answer in the box.
h(−2)=
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

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

Determine the 50th term in the sequence defined by an = -11+ 5(n − 1).
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'.

Step-by-step explanation:
A line with a positive slope is parallel to one of the lines shown. What is its slope? Use the graph shown below.
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
