Alright first off 8 filters cost $39.92 and out goal is to find the cost of 6 filters Set this up as a proportion. 8 = $39.926 = x
So let find x
x = (6)($39.92) / 8 = $29.94 <span>It costs $29.94 to buy 6 filters.</span>
Answer:
y = 1/3 x + 4
Step-by-step explanation:
The slopes of perpendicular lines are negative reciprocals. The given line is
y = -3x + 7
which is already in the slope-intercept form, y = mx + b, where m is the slope.
The slope of the given line is -3.
The slope of the perpendicular is the negative reciprocal of -3 which is 1/3.
The line we are looking for has an equation of the form
y = 1/3x + b
We need to find b. We use the x- and y-coordinates of the given point as x and y in the equation above, and we solve for b.
y = 1/3x + b
5 = (1/3)(3) + b
5 = 1 + b
4 = b
Now that we know that b = 4, we replace b with 4 in the equation
y = 1/3x + b to get the answer.
Answer: y = 1/3 x + 4
2.25 is the correct answer
Answer:
1/1296
Step-by-step explanation:
The probability of rolling any particular number is 1/6. So the probability of rolling a particular sequence of four numbers is:
(1/6) (1/6) (1/6) (1/6)
1/1296
≈ 0.0008
