True is the answer . According to minimum wage act

Answer:c

Step-by-step explanation:

Answer:

Children = 51

Adults = 42

Students= 84

Step-by-step explanation:

Children = $2

Students = $3

Adults = $4

Total sales = $522

Total people who attended = 177

Adults =a

Students = s= 2a

Children = c

c+s+a = 177 (1)

2c+3s+4a=522 (2)

Substitute s=2a into the equations

c + 2a + a = 177

c + 3a = 177 (3)

2c + 3(2a) + 4a = 522

2c + 6a + 4a = 522

2c + 10a = 522 (4)

c + 3a = 177 (3)

2c + 10a = 522 (4)

Multiply (3) by 2

2c + 6a = 354 (3b)

2c + 10a = 522

Subtract (3b) from (4)

10a - 6a = 522 - 354

4a = 168

Divide both sides by 4

a= 168/4

= 42

a= 42

s= 2a

= 2(42)

= 84

s= 84

Substitute the value of s and a into (1)

c+s+a = 177 (1)

c + 84 + 42 = 177

c + 126 = 177

c = 177 - 126

= 51

c=51

Children = 51

Adults = 42

Students= 84

Its 10 because if you do 1/2 plus 1/2 and so one till you get 5 it is ten

**Answer:**

THe area of the arc is 8.75 m²

**Step-by-step explanation:**

In order to calculate the are of the sector we need to know the radius of the circle. For that we can use the formula for the area of the circle, which is shown below:

area circle = pi*r²

Applying the data from the problem, we have:

45 = pi*r²

pi*r² = 45

r² = 45/pi

r = sqrt(45/pi) = 3.7846 m

Therefore the area of the arc is:

arc's area = angle*pi*r²/360

arc's area = 70*pi*(45/pi)/360 = 70*45/360 = 8.75 m²

THe area of the arc is 8.75 m²
