Answer:

B

Step-by-step explanation:

To make the survey fair, every student in the school has to have an equal chance to be selected to take the survey.  The first scenario would only allow friends of the committee members to be selected,  but the second one would give a chance to all students.

AnnZ [28]

Answer:

l( longer side ) = 12cm

S (shorter side) =9cm

D's( distance between the shorter side). ( It is also the height. I hope you got the clue…)

Anyway,

Area=9X8=72cm^2

Distance of the longer sides is

Area/the length of the longer side

72/12=6cm…

Distance between the longer sides is 6cm

Hope this helps…

Two sides of an obtuse triangle measure 9 inches and 14 inches. The length of longest side is unknown. What is the smallest poss
julia-pushkina [17]

Answer:

17 inches

Step-by-step explanation:

An obtuse triangle is the triangle in which one of the side is the longest. It contains an obtuse angle and the longest side is the side that is opposite to the vertex of the obtuse angle.

Let the three sides of the obtuse triangle be a, b and c respectively with c as the longest side. Let a = 9 inches and b = 14 inches.

Now we know that for an obtuse triangle,

$c^2 > a^2 +b^2$

$c^2 > (9)^2 +(14)^2$

$c^2 > 81 +196$

$c^2 > 277$

c > 16.64

Therefore the smallest possible whole number is 17 inches.
