Answer: They need 225 liters of water.
Step-by-step explanation:
If 200 people need 900 liters of water, we divide 900 and 200 which gets us 4.5. That means ONE PERSON needs 4.5 liters of water.
Then we multiply 4.5 by 50 to get the amount of liters 50 guests need.
Answer:
<h3>y + 2 = 3/7(x-7)</h3>
Step-by-step explanation:
The point-slope form of the equation will be expressed as;
y - y0 = m(x-x0) where;
m is the slope
(x0, y0) is the point on the line
Given
Slope m = 3/7
Point (x0, y0) = (7, -2)
Substitute into the equation;
y - y0 = m(x-x0)
y - (-2) = 3/7 (x - 7)
<em>y + 2 = 3/7(x-7)</em>
<em>Hence the equation in point-slope form is y + 2 = 3/7(x-7)</em>
The model is 3 inches, since 3 times 3 is 9 and 1 times 3 is 3.
