Step-by-step explanation:
A city pool sells full-day and half-day passes during the summer. The goal is to make $1000 each day from pool pass sales. The graph shows the number of full-day and half-day passes they need to sell to make $1000.
the maximum number of half-day passes the pool can sell and make exactly $1000
From the graph the half day passes is on x axis.
WE can see that the maximum on x is 200
Half day passes starts at 0 and ends at 200
200 is the maximum number of half-day passes the pool can sell and make exactly $1000
Answer:
160
Step-by-step explanation:
Consecutive numbers have a difference of 1 between them.
Let n be the first number then n + 1 and n + 2 are the second and third numbers. Summing them gives
n + n + 1 + n + 2 = 477, that is
3n + 3 = 477 ( subtract 3 from both sides )
3n = 474 ( divide both sides by 3 )
n = 158
The 3 consecutive numbers are 158, 159, 160
The third number is 160
Step-by-step explanation:
when two lines are perpendicular to each other( the product of their slope; m1m2 = -1)
m1 = -1/m2
m1 = -1/-6= 1/6
using the formula m= y-y1 / x - x1
1/6 = y -7 /x - 3
6(y -7) = x -3
6y -42 = x - 3
6y - x -39 =0
Divide both sides by 6
y - 1/6 x - 13/2= 0
y = 1/6 x + 13/2
