Answer:
(-11 +/- sqrt 21) / 10
or
-0.64 , -1.56 to the nearest hundredth.
Step-by-step explanation:
9v^2 + 11v + 5 = 4v^2
5v^2 + 11v + 5 = 0
Using the quadratic formula:
v = [ - 11 +/- sqrt(11^2 - 4*5*5) ] / 2*5
= (-11 +/- sqrt 21) / 10
= -0.64 , -1.56 to the nearest hundredth.
Because these triangles are congruent, then angle a is the same degree measure as angle x; angle b is the same as y; and angle c is the same as z. We also know that, because of the Triangle Angle-sum Theorem, all the angles of a triangle have to add up to equal 180 degrees. So for us that means that a+b+c(which is also z) = 180. 50 + 2x + 40 + 4x + 8 = 180. Combining like terms we have 6x + 98 = 180. Subbtracting 98 from both sides gives us 6x = 82 and x = 13 2/3
Answer:
1 3 6 10 15 is added by 2345
and 2345 is added by 111
Step-by-step explanation:
1+2= 3 3+3=6 6+4=10 10+5=15 so it's added by 2345
2+1=3 3+1=4 4+1=5 so that's why it's added by 1

Answer:
36/32 or 1 1/8 (same thing)
Step-by-step explanation:
9 gallon / 32 quarts
First, you have to convert 9 gallon to quarts to match the denominator. In the table, it says that 1 gallon = 4 quarts, so you have to do, 9 x 4 which gives you 36. Now that the fraction is in the same form of units, 36 quarts / 32 quarts, you will have to write it as a mix fraction or you can just leave it as 36 quarts / 32 quarts. If you want it in mix fraction, it is 1 1/8.
