Answer:
Area = 40mm
Example:
The below-solved example problem may be useful to understand how the values are being used in the mathematical formulas to find the trapezoid area.
Example Problem :
Find the area of a trapezoid having the bottom length a = 15 cm, top length b = 12 & height h = 9 cm?
Solution :
The given values
bottom length a = 15 cm
top length b = 12 cm
height h = 10 cm
Step by step calculation
formula to find area = ((a + b)/2) h
substitute the values
= ((15 + 12)/2) x 9
= 121.5 cm2
Okay so you would use PEMDAS (parentheses, exponents, multiply, divide, add, and subtract) so there are no parentheses so you do the exponents

then you do the rest so 100+36=136 and then 136-9=127 so the answer is 127
Answer:
8?
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given that:
all coins are same;
The same implies that the number of the non-negative integral solution of the equation:


Thus, the number of the non-negative integral solution is:

(b)
Here all coins are distinct.
So; the number of distribution appears to be an equal number of ways in arranging 35 different objects as well as 5 - 1 - 4 identical objects
i.e.


(c)
Here; provided that the coins are the same and each grandchild gets the same.
Then;




Thus, each child will get 7 coins
(d)
Here; we need to divide the 35 coins into 5 groups, this process will be followed by distributing the coin.
The number of ways to group them into 5 groups = 
Now, distributing them, we have:

Answer:
f(x) = -0.5x
Step-by-step explanation:
.25*8 = 2 which is really a slope of 2/1
place a negative in front flips it over the y axis and flipping the slope flips it over the x axis.
