Answer: C 41 degrees
Step-by-step explanation:
answer:
x = 4
y = 19
step-by-step explanation:
- we know that this is a parallelogram, so opposite sides are equal
- this is one of the properties of a parallelogram
therefore,
segment AB = segment DC <em>and</em> segment AD = segment BC
- now plug in the expressions according to what we know (& solve)
AB = DC
5x - 13 = 9x - 29
-13 = 4x - 29
16 = 4x
x = 4
AD = BC
3y - 11 = 2y + 8
y - 11 = 8
y = 19
Answer:
(x, -(A/B)*x)
Step-by-step explanation:
We have the line:
A*x + B*y = 0
And we want to find the coordinates of the point that lie on this line.
Where the coordinates of a point P are written as (x, y)
The first step to do this, is to write the line in a more general way, we can do this by isolating y in the left side of the equation:
A*x + B*y = 0
B*y = -A*x
y = -(A/B)*x
Now, for a random point (x, y), if we replace the "y" by the equation above, we know that the point will also lie on the line.
This means that the coordinates of the points that lie on the line are of the form:
P = (x, -(A/B)*x)
there is 0.015 kilos in 15 grams. if each can weighs 0.015 and he gets paid 50p per KG. 0.015 X 66 will get you 1 kilogram! so you have 66 cans to get 1 kg worth of cans. so there is 15 dollars and each kg is worth 50p- so 66 cans is = 50p
and there is 2 KG per dollar so 15 X 2 is 30! and then 66 X 30 is 1980!
66 for each KG and 30 represents how many 50p's are needed for 1 dollar!
so that is 1980 cans to get 15 dollars!
Volume = 5 cm * 10 cm * 2 cm
volume = 100 cm³
massa = 700 g
Densidade = massa / volume
D = 700/100
D = 7 g / cm³
