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

Use the diagram to find the measure of ∠PML.

Answers

Answer:

31 degrees

Step-by-step explanation:

We know that if the angle P is equal to 121+x=180 because when it is reflected, they both have to add up to 180. Therefore, P is equal to 59 degrees. We know that angle L is 90 degrees because there is a square. Therefore, we have to do 180-59-90 to find angle PML. 180-149. Angle PML is equal to 31 degrees.

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%

We move all terms to the left:

z/6+15-(24)=0

We add all the numbers together, and all the variables

z/6-9=0

We multiply all the terms by the denominator

z-9*6=0

We add all the numbers together, and all the variables

z-54=0

We move all terms containing z to the left, all other terms to the right

z=54

Step-by-step explanation: hope it helps

Answer:

z = 54

Step-by-step explanation:

[tex]\frac{z}{6}+15=24[/tex]

[tex]6(\frac{z}{6})+15=24[/tex]

z + 15 = 24

z + 15 - 15 = 24 - 15

[WILL GIVE BRAINLY] An angle measures 122° more than the measure of its supplementary angle. What is the measure of each angle?

Answers

The measure of the angle will be equal to 58°.

What is the supplementary angle?

The supplementary angles are defined as the angles whose sum is equal to 180°

here the angle is 122° degrees more than its supplementary angle.

We know that the sum of the two supplementary angles is given as:-

Suppose the known and the unknown angles are A and B respectively.

∠A  +  ∠B  =  180°

122  + ∠B  = 180°

∠B  =  180-122= 58°

Hence the measure of the angle will be equal to 58°.

Answer:

Step-by-step explanation:

since vertical angles congruent

12a = 36

a = 3

A line is 180 degrees so 12a = 36

180-36 = b and c

since vertical angles are congruent

b and c = 144
