The answer is 16 inches, we can get the medians length of the trapezoid by using the formula: EF = (BC + AD) / 2. Given: EF = the medians length; BC = top base
= 12 inches; and AD = bottom base = 16 inches.
Therefore:
EF = (12 + 16)/2
EF = 28 / 2
EF = 14 inches’ medians
length is the average of the two bases of trapezoid.
Answer:
9%
Step-by-step explanation:
Let the required number be 100.
Now, according to the question, the number is first increased by 30 %
⇒ 100 + 30 % of 100
⇒ 100 + [(30*100)/100]
⇒ 100 + 30
⇒ 130
Then, it is decreased by 30 %
⇒ 130 - (30 % of 130)
⇒ 130 - [(30*130)/100]
⇒ 130 - 39
⇒ 91
Net Decrease = 100 - 91
= 9
Percent Decrease = (Change in number*100)/100
⇒ (9*100)/100
= 9 %
Answer:
D = { -4,-1,3,5,6}
Step-by-step explanation:
The domain is the x values or the inputs
D = { 3,6,-1,5,-4}
We normally put them in order from smallest to largest
D = { -4,-1,3,5,6}
E, g, a .
It’s like division and multiplication
Answer:
216 cubes.
Step-by-step explanation:
The easiest way to take on this problem is to divide the side of the bigger cube by the smaller one.
Then, as in with volume, we cube this value to find the number of cubes necessary to fill such a space.
