Answer:
h=23
Step-by-step explanation:
triangle equals 180 degrees
180-40=140
140/4=35
Answer:
Step-by-step explanation:
finding PR ( public relations :D , not that PR , the PR on this triangle thingy )
use law of cosines, again
c=sq rt [ a^2+b^2﹣2*a*b*cos(C) ]
where
c=PR
a= 9
b = 22
C = the angle of Q or 180 = 97+24+Q so Q = 180-97-24 = 59°
they tried to trick us.. by not giving us the angle C for the above cosine formula , but we figured out their diabolical plan :D yay super hero math
then
PR = sq rt [ 9^2 + 22^2 - 2*9*22*cos(59) ]
PR = sq rt [ 81 + 484 -203.9550777 ]
( notice that now it is a subtraction sign instead of a plus sign, this time? )
PR = sq rt [361.0449 ]
PR = 19.0011
to the nearest 10th
19.0 :)

Step-by-step explanation:
Answer:
26 lbs
Step-by-step explanation:
there are four 1/4 hours in an hour 1/4 x4=1 hour
6 1/2 x4= 26 lbs in an hour
Answer:
E (none of the above)
Step-by-step explanation:
1 = k(1.5)
2 = k(3)
Therefore, k = 2/3
and when we put k = 2/3 into all values in the table we notice it is right
but it could be "A" also if the relationship was cups of water to cups of rice
