Answer:surface area = 2lw + 2lh + 2hw = 2(lw+lh + hw) = 2(12x8 + 12x4 + 4x8) = 2(96+48+32) = 2(176) = 352 square inches
Step-by-step explanation:divide by 144 to convert to square feet = 352/144 = 2 4/9 ft^2= 2.4 square feet, rounded to one decimal place Hop it helps.
The first step is to find the slope of the given line by putting its equation in the form y = mx + b.
9y = x - 18
Dividing both sides by 9, gives:
y = (x/9) - 2
The slope of the given line is therefore 1/9.
Let the slope of the perpendicular line be m.
The product of the two slopes must equal -1 for the lines to be perpendicular.

Therefore m = -9.
At this stage the equation of the required line is y = -9x + b.
Now we need to find the value of b.
Plugging the given values of a point on the line (6, -1) into the equation gives:
-1 = -54 + b; from which b = 53.
The required equation for the line is:
f(x) = -9x + 53.
Answer:
This is a Retrospective study
Step-by-step explanation:
Retrospective study is a study that compares two groups of people; those with disease or condition under study and a very similar group of people who do not have the disease or condition.
Here they are compring those men with high blood pressure who drank and those with no high blood pressure and don't drink.
