The area of a rectangle is calculated as length times its width. So, for the given area above, the expression should b written as:
20 = LW
To know the length for various measurement of the width, we can write it by:
L = 20 / W
You can substitute any measurement to W and you can obtain the corresponding value of the length.
Answer:
The answer is A
Step-by-step explanation:
4.53 - 4.06 = .47
.47 is 10.4% of 4.53
Answer:
It is the Quadrilateral DEFG has only one set of opposite angles that are congruent and Quadrilateral DEFG has one diagonal that bisects the other diagonal.
Step-by-step explanation:
In any right triangle ABC, with right angle A we have the following:
and
.
This means that the sine of a non 90° angle, is equal to the cosine of its complementary angle.
Thus,
.
(Take a look at the picture. From the definition of trigonometric ratios in right triangles we have :
and
)
Answer: 19/20
Okay, (Assuming this is workings, dunno if it's the right method) multiply the bottom equation by -4 (for simplicity's sake here) so you get -4x+12y=12. (Changing the signs here) then to get rid of the x in the equation, add the two together.
4x-2y=8
+
-4x+12y=12
=
10y=20
Divide 20 by 10 to get y=2. then put the answer for y back into one of the equations.
x- 3(2)=-3
x-6=-3
x=3
in sum, y=2 and x=3.
That is how it's done, hope it helps:)
