Most likely, polygon <span>ABCD</span> has sides of known lengths.
It is also likely that one of the sides of polygon <span>EFGH</span> (not <span>EH</span>) is also known. For instance, its side <span>EF</span>.
If the above is true, we can find the scaling factor as a ratio between lengths of corresponding sides:
<span>r=<span><span>EF</span><span>AB</span></span></span>
Since this ratio is constant for any two corresponding lengths,
<span>r=<span><span>EH</span><span>AD</span></span></span>
From the last two equations we can derive:
<span>EH=AD⋅<span><span>EF</span><span>AB</span></span></span>

Hi There!
Answer:
$24
Step-by-step explanation:
= 1/4 + 1/3
= 3/12 + 4/12
= 7/12
7/12a + 8 = 22
Subtract 8 to both sides of the equation.
7/12a + 8 - 8 = 22 - 8
Simplify
7/12a = 14
Switch
a = 12/7 * 14
Simplify
a = $24
Hope This Helps :)
Area of a trapezoid:
A = 1/2 * ( b 1 + b 2) *h
b 1 = 8 m, b 2 = 1 m, h = 5 m;
A = 1/2*( 8 + 1 ) * 5 = 1/2 * 45 = 22.5
Answer: B ) 22.5 m²
Answer:
a) 0.064
b) 0.002
Step-by-step explanation:
a) Assuming that the batteries' voltage levels are independent
Probability = 0.8 * 0.8 = 0.64
b) batteries' voltage levels are dependent
20/19 (0.064)^19 *0.036 + 20/20 (0.064)^20 *0.036^0
= 0.002
