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
