Answer:
x= -10 1/5 or -10.2
Step-by-step explanation:
Answer:
48 sq. units
Step-by-step explanation:
The area of a trapezoid is given by half sum of the bases multiplied by the height

where a and b are the two parallel sides of the trapezoid and h is the height or amplitude of the trapezoid
But you are aware that, the median of a trapezoid is equal to half the sum of the bases, thus the first part of the formulae is covered by the median

Hence area, A, of a trapezoid is simplified to product of median and amplitude

Answer: 6/25</h3>
======================================================
Explanation:
The table shows the spinner lands on "4" exactly 12 times out of the 50 total.
12/50 = (2*6)/(2*25) = 6/25
In decimal form that is 6/25 = 0.24 which converts to 24%
Answer:
17
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to

we have

Step 1
<u>Find the slope GH</u>

substitute in the formula



Step 2
<u>Find the slope HJ</u>

substitute in the formula



Step 3
<u>Find the slope JG</u>

substitute in the formula



Step 4
Verify if triangle GHJ is a right triangle
we know that
if two lines are perpendicular, then the product of their slopes is equal to minus one
so

compare slope GH with slope JG
we have


-----> side GH and side JG are perpendicular
The triangle GHJ is a right triangle
