Answer:
£59.25
Step-by-step explanation:
It appears you can measure the height of the trapezoid [trapezium :-) ??]. If you can't, you can use the Pythagorean Theorem (image attached). Draw a line from the upper right-hand corner down to the baseline--the 20m side. You'll form a right triangle with one leg <em>h</em> , hypotenuse 17m and the other leg 8m (the difference between 20m and 12m).
(leg)^2 + (leg)^2 = (hypotenuse)^2
<em>h</em>^2 + 8^2 = 17^2
h^2 + 64 = 289
h^2 = 225
h = 15m
The area of the trapezium is
where the <em>b</em>'s are the lengths of the two bases (upper and lower sides).
m^2
One can of weedkiller covers 100 m^2 of area. You'll need 3 cans (2 cans isn't enough, and you can't buy a fraction of a can). Tricky question!
Three cans will cost 3 x 19.75 pounds = £59.25
Answer: y = − 3/2 x + 8
Step-by-step explanation:
Find the Perpendicular Line
Solve −2x + 3y = −6.
y = −2 + 2x/3
Find the slope when y = −2 + 2x/3 .
m = 2/3
The equation of a perpendicular line must have a slope that is the negative reciprocal of the original slope.
perpendicular = 
Simplify to find the slope of the perpendicular line.
perpendicular = −3/2
Find the equation of the perpendicular line using the point-slope formula.
y + 1 = − 3/2
⋅ (x − 6)
Write in y = mx + b form.
y = − 3/2 x + 8
The answer is 0 because If two events are mutually exclusive, then the probability of either occurring is the sum of the
probabilities of each occurring.
Hope that Helps :)
Answer:
The dependent variable is A
The independent variable is w
Step-by-step explanation:
Given

Required
Identify the variables
In 
The value of w is independent of the value of A.
In other words:
A derive its own value from w; by multiplying 25 and w.
Take for instance:

The value of A would be:


Hence:
The dependent variable is A
The independent variable is w
Answer:
ok so the graph tells you 24 seconds by 4 ounces
Step-by-step explanation:
The point where both lines meet is the point where they are both equal.
The point where both lines meet is (24,4)
Since the x-axis represents seconds the x-coordinate will represent the number of seconds it takes for them to be equal which is 24.
Since the y-axis represents ounces the y-coordinate will represent the number of ounces they have when they are equal which is 4.
