Answer:
y = 0
Step-by-step explanation:
Any point on the x- axis is (x, 0 ), that is the y- coordinate of all points is zero.
For this reason the equation of the x- axis is y = 0
Answer:
number of children ticket sold = 70
number of adult ticket sold = 70 × 3 = 210
number of student ticket sold = 500 - 4(70) = 500 - 280 = 220
Step-by-step explanation:
A local theater sells out their show. They sell all 500 tickets for a total of $7920 .00 . The total number of ticket sold is 500.
let
Number of children ticket sold = a
Adult ticket sold = 3a
Student ticket sold = 500 - 3a - a = 500 - 4a
Total cost = 7920
7920 = 12(a) + 15(500 - 4a) + 18(3a)
7920 = 12a + 7500 - 60a + 54a
collect like terms
7920 = 12a - 60a + 54a + 7500
7920 - 7500 = 6a
420 = 6a
divide both sides by 6
a = 420/6
a = 70
number of children ticket sold = 70
number of adult ticket sold = 70 × 3 = 210
number of student ticket sold = 500 - 4(70) = 500 - 280 = 220
Answer:
Idek
Step-by-step explanation:
The formula for volume of a sphere is πr²h. The diameter is 14 ft, and the radius is 1/2of the diameter, so the radius is 7. The depth is the height, which is h. Now, substitute the known values into the expression:
π*7²*2
49π*2
98π is the exact amount of sand needed to fill the sandbox, and the approximate value is 307.87608.
