Answer:
243 students' favorite color is red
Step-by-step explanation:
if 55% of the students said their favorite color was blue, then 45% chose that red was their favorite color
we can get 45% of 540 using a cross-multiplication equation
45% is 45/100
45/100 is to ?/540
the (?) represents the value of students who chose red as their favorite color (we do not know this but we can figure it out using cross-multiplication)
45 times 540 is 24300
24300/100 = 243.

Answer:
Area of the base = 
Step-by-step explanation:
We know that volume of rectangular prism = (Area of base) x (Height)
or [Area of base] = [Volume]/[Height]
So basically we need to divide given area by given height to find the answer.
given height is (x+2) that means (x+2) must be factor of volume equation
or x=-2 must be root of volume equation so write down coefficients of volume equation then we divide by -2 as shown in attached picture.
Last digit on the right is always remainder.
Remaining coefficients {2, 5, -18} will give the area equation: 
Hence final answer is:
Area of the base = 
Answer:
h = A / ( 1/2 a - 1/2 b)
Step-by-step explanation:
A = ½ ah - ½ bh
Factor out an h
A = h( 1/2 a - 1/2 b)
Divide each side by ( 1/2 a - 1/2 b)
A / ( 1/2 a - 1/2 b) = h ( 1/2 a - 1/2 b)/ ( 1/2 a - 1/2 b)
A / ( 1/2 a - 1/2 b) = h
h = A / ( 1/2 a - 1/2 b)
Answer:
2/9
12.5%, 30% ,45%
Step-by-step explanation:
Possible outcomes
W = wild
S = sandy shores
G = green hills
W6 W7 W10
S6 S7 S10
G6 G7 G10
There are 9 outcomes
2 are over a week without hills (W10 and S10) and
P(10 days not at hills) = # more than 7 days no hills/total
=2/9
We need all the numbers in the same form, I will change to decimal
1/8 = .125
30% = .30
.45
Smallest to largest
.125 <.30 <.45
1/8 < 30% < .45
Changing to percent form
12.5%, 30% ,45%
1+4=5 2+5=7 3x6=18 8+11=19
