The wrestler's weight before he went on his diet is 78 kg
<h3>How to find the y-intercept?</h3>
The formula for slope is;
m = (y2 - y1)/(x2 - x1)
Thus, using two points we have;
m = (93.6 - 85.8)/(3 - 1.5)
m = 5.2
At the start of his diet, time in months = 0 months and so x = 0. Thus;
5.2 = (85.8 - y0)/(1.5 - 0)
5.2 * 1.5 = 85.8 - y0
y0 = 85.8 - (5.2 * 1.5)
y0 = 85.8 - 7.8
y0 = 78 kg
Thus, the wrestler's weight before he went on his diet is 78 kg

Answer:
(a) 13536.10J
(b) 27072.20J
Step-by-step explanation:
(a) Height of tank (h) = 4 feet = 4/3.2808 = 1.22m
Volume of water in full tank = 4ft×5ft×4ft = 80ft^3
Volume of water in half tank = 1/2 × 80ft^3 = 40ft^3
Density of water = 62.4lb/ft^3
Mass of water = density × volume = 62.4 × 40 = 2496lb = 2496×0.45359kg = 1132.16kg
Work done to empty half of the tank = mgh = 1132.16×9.8×1.22 = 13536.10J
(b) Work done to empty all of the tank = 2 × work done to empty half of the tank= 2 × 13536.10J = 27072.20J
Answer:
median = 9.5
mode = no mode
Step-by-step explanation:
the median is the middle number
there are 8 numbers
so the median is number 4 and 5 added together and then divided by 2
9+10/2 = 9.5
the mode is the most often
there is no number that appears the most often so there is no mode
The correct answer is number line B.
Explanation:
We are given the inequality x >= -7, that means we have to represent on a number line all numbers that are greater than -7, including -7. that is correctly represented on the number line B, because the black full dot means that -7 is included and the direction of the line goes in the way which is greater than -7.
