Answer:
x=8
z=132
Step-by-step explanation:
We know that 6x and 4x+16 are vertical angles, so they are equal
6x= 4x+16
Subtract 4x from each side
6x-4x = 4x-4x+16
2x =16
Divide each side by 2
2x/2 =16/2
x =8
We also know that 6x and x form a straight line
6x+z = 180
6(8) + z =180
48+z =180
Subtract 48 from each side
48-48 +z =180-48
z = 132
Probability of raining=0.45
Probability of not raining=1-0.45=0.55
The expected earning will be given by:
E(x)=240(0.55)+320(0.45)
E(x)=132+144
E(x)=276
Answer: $276
Answer:
75 cubic cm.
Step-by-step explanation:
5·9=45 - Find the base
45·5=225 - Multiply the base by height
225÷3=75 - Divide the total by 3
75 is the answer
since she paid $5 admission subtract it from $7.25
that is $2.25
then 2.25/ 0.75 and its 3
3 hours
