Total numbers of cars present in the rally is 135
Amount paid by a single driver to participate in the rally = $25
Total amount generated by the participation fee from each driver is equal to the sum of amount paid by all the 135 cars.
Since we cannot add $25 for 135 times, we use multiplication operation.
Total amount = amount paid by one single driver multiplied by the total number of cars.
Total amount = 
$ .... Answer
Answer:
Step-by-step explanation:
The vertical line test can be used to determine whether a graph represents a function. ... If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because that x value has more than one output. A function has only one output value for each input value.
Hello,
if the question is to solve the equation:
1) log must exist:
a)==>2r²-27>0==>(r-√(27/2))(r+√(27/2))==> outside the roots
r<-√(27/2) or r>√(27/2)
b)==>3r²+12r>0 ==>3r(r+4)>0 ==>outside the roots
r>0 or r<-4
==>r<-4 or r>√(27/2)=3.6742...
If this is realized:
2r-27=3r²+12r
==>r²+12r+27=0
Δ=12²-4*27=36=6²
r=(-12+6)/2=-3 or r=(-12-6)/2=-9
One solution r=-9

Answer:
10 girls are not on either team
Step-by-step explanation:
first subtract 6 from 8 to get 2 (since it's easier) because those 6 girls are on the math league team as well
next add 2 and 13 to get 15
last subtract 15 from 25 to get 10
