Mr. Johnson purchased 20 concert tickets for a total of $225. The concert tickets cost $15 for adults and $10 for children under twelve. How many tickets for children under twelve did Mr. Johnson purchase?

Answers

Answer:

15

Step-by-step explanation:

15a +10c=$225
a + c = 20
Rewrite the second equation so it has a value for c
c= 20 -a
Now using substitution method replace the c for the given value
15a + 10(20-a)=225
15a +200-10a=225
Combine like terms
5a +200=225
5a=25
a=5
So 5 adult tickets were bought and 15 children tickets

a. an equal chance or 50-50

The figure below shows a shaded circular region inside a larger circle:
r3 inches
R5 inches
What is the probability that a point chosen inside the larger circle is not in the shaded region?
O 24%
O 36%
O 50%
O 64%

Answers

Answer:

Probability is 64%

Step-by-step explanation:

Given the smaller circle which is shaded whose radius is denoted by r and  the largest circle whose radius is denoted by R

                     r = 3 inches

                    R = 5 inches

Step 1 : To calculate the area of shaded region.

Area of circle =

⇒ Area =    

          =   square inches

Step 2 : To calculate the area of larger circle.

Area of circle =

⇒ Area =    

            =  square inches

Step 3 : Calculate the probability that a point chosen from shaded region

Probability = Area of shaded region/Area of larger circle.

                  =  /

                  =  

                  =  0.36 = 36%

Step 4 : calculate the probability that a point chosen inside the larger circle is not in shaded region.

Probability = 1 - 0.36

                  = 0.64 = 64%

Hence the probability is 64%

Rewrite the expressions without the absolute value sign.

Answers

If x< -5 then x+5 < 0
but the absolute value of x+5 > 0
X+12 >-11
X> -23
But also you have to write a second equation to get both possible answers for x since it was in absolute value
X+12>11
X>-1
