Answer:
25 gallons
Step-by-step explanation:
Given:
total no. of gallons= 50
Percentage of sulfuric acid= 50%
Number of gallons of sulfuric acid= total no. of gallons x Percentage of sulfuric acid
Putting values in above equation:
Number of gallons of sulfuric acid= 50 x 50/100
= 50 x 1/2
= 25 !
X + y = 47
x = y + 13
y + 13 + y = 47
2y + 13 = 47
2y = 47 - 13
2y = 34
y = 34/2
y = 17
x = y + 13
x = 17 + 13
x = 30.....longer piece is 30 inches
sec((-(4 * pi)) / 3 radians) = -2

Step-by-step explanation:
how where is the graph cause I don't understand that
Answer:
y = 10x - 2
Step-by-step explanation:
From the table attached,
Let the equation of a line passing through two points 
and 
is,
y = mx + b
Here, m = slope of the line
b = y-intercept
Since, m = 
Slope of the line passing through (0, -2) and (1, 8) will be,
m = 
m = 10
y-intercept 'b' = -2 [Output value at x = 0]
Therefore, equation of the line will be,
y = 10x - 2
