B. One solution (I think)
Idk man shjsskbabjbzhksjsjssnn in h
You have to use pythagorean theorem which means a^2+b^2=c^2 because no angle is given
c is going to be the longest side or opp to 90 degree.
so c=13 and b=12
a^2+ (12^2)= 13^2
a^2 + 144 = 169
a^2=25
a=5
solve for a, can you do that?
a=5
hope that helps
I think ur answer would be C.
Answer:
2/9
Step-by-step explanation:
28 marbles in all
"Half of the marbles are red."
28/2 = 14 red
"Half of the non-red marbles are white..."
14/2 = 7 white
"...and the rest are blue."
25 -14 -7 = 7 blue
"Todd chose a <u>white marble</u> at random... " -from the bag that has...
14 red 7 white 7 blue
"... and <u>kept it</u>."- so now the marbles left in the jar are...
14 red 6 white 7 blue
P (white) = Number of white marbles/ Total number of marbles = 6/27 = 2/9
