Answer:
10
Step-by-step explanation:
How you find LCD (lowest common denominator) is that you have to look at the denominator (the bottom number) and try to find the lowest multiple between both of the numbers that is on the bottom (in this case it is 2 and 5). Sometimes you have to multiply both denominators together to get a LCD.
Example of multiplying two denominators together to get an LCD:
1/3 and 1/13 LCD is 39 because you multiply 3 and 13.
1/5 and 1/4 LCD is 20 because you multiply 5 and 4.
What is the height of the trapezoid?
The area of the trapezoid is given by the formula A= (a+b)/ 2 * h
in this question a= 8, b= 10, A= 108 inches², and h is what we have to find, substitute what we have got into the formula and you will have:
108= (8+10) /2 *h
108= 9 *h
h= 108/9
h= 12 inches
Answer:
The required equation is .
Step-by-step explanation:
We are given,
The table showing the boiling points of water at different altitudes.
We will find the slope of the equation using .
Taking points (0,212) and (0.5,211.1) and substituting in the formula,
Slope is
i.e. Slope is
i.e. Slope is -1.8
Substituting slope and the point (0,212) in the equation , we will find the value of y-intercept 'b'.
That is, i.e. b= 212
Thus, the required equation is.
