A rectangular room is 2 times as long as it is wide, and its perimeter is 30 meters. Find the dimension of the room.
Answers
Answer:
5 by 10
Step-by-step explanation:
We know that the equation of a perimeter of a recangle is 2(l)+2(w), l being length and w being width. We know that l=2w. So the perimeter of this room would be:
2(2w)+2(w)=30
4w+2w=30
6w=30
w=5
l=2w
l=10
the dimensions are 5 by ten
The dimensions of the rectangular room with a perimeter of 30 meters and length twice its width are 5 meters wide and 10 meters long.
Explanation:The subject matter of your question falls into the category of Mathematics, specifically dealing with basic geometry and algebra. You want to find the width and length of a rectangular room given that it is twice as long as it is wide, and that its perimeter is 30 meters.
The perimeter P of a rectangle is calculated by the formula 2L + 2W = P, where L is the length and W is the width. Since the length is given as twice the width, we can substitute 2W for L in the formula and get 2(2W) + 2W = 30, which simplifies to 6W = 30. Solving for W, we find that W = 5. Therefore, the width of the room is 5 meters and the length of the room is 2W = 2*5 = 10 meters.

Triangle ABC is similar to triangle WYZ. select all angles whose tangent equals 3/4
Answers
Answer:
∠B
∠Y
Step-by-step explanation:
we know that
In the right triangle ABC
[tex]tan(B)=\frac{AC}{BC}[/tex] ----> opposite side to angle B divided by the adjacent side to angle B
substitute the values
[tex]tan(B)=\frac{3}{4}[/tex]
Remember that
If two triangles are similar, then the corresponding sides are proportional and the corresponding angles are congruent
so
∠A=∠W
∠B=∠Y
∠C=∠Z
therefore
[tex]tan(B)=tan(Y)[/tex]
Base on the fact that the triangle ABC and WYZ are similar, the angles whose tangent equals 3 / 4 are ∠B and ∠Y
What are similar triangles?Similar triangle are only different in sizes but are of the same shape.
Similar triangles, corresponding sides are always in the same ratio. Corresponding angles of similar triangles are always congruent. Therefore,
∠A = ∠W
∠B = ∠Y
∠C = ∠Z
Therefore, let's find all angles in the similar triangles whose tangent is equal to 3 / 4 .
tan ∅ = opposite / adjacent
Since,
tan B = 3 / 4
Then
tan Y = 3 / 4
Therefore,
The angles whose tangent equals 3 / 4 are ∠B and ∠Y

If f(x) = 1-x which value is equivalent to |f(I)|
Answers
Answer:given that
F (x)=1-x
Step-by-step explanation:
Answer:
The value of |f(i)| is √2.
Step-by-step explanation:
The given function is
[tex]f(x)=1-x[/tex]
We need to find the value of |f(i)|.
Substitute x=i in the given function.
[tex]f(i)=1-i[/tex]
Taking modulus on both the sides.
[tex]|f(i)|=|1-i|[/tex]
Using the formula for modulus of a complex number, we get
[tex]|f(i)|=\sqrt{(1)^2+(-1)^2}[/tex] [tex][\because |a+ib|=\sqrt{a^2+b^2}][/tex]
[tex]|f(i)|=\sqrt{1+1}[/tex]
[tex]|f(i)|=\sqrt{2}[/tex]
Therefore the value of |f(i)| is √2.

If the graph of y= |x| is translated so that the point (1, 1) is moved to (4,1), what is the equation of the new graph?
Answers
Answer:
The new equation is y= (x-3)
Step-by-step explanation: we know that the point (1, 1) is moved to (4,1).
So, the rule of the translation is: [tex](x,y) -----> (x+3, y)[/tex]
that means the translation is 3 units to the right
Answer:
[tex]y=|x-3|[/tex]
Step-by-step explanation:
The parent absolute function is
[tex]y=|x|[/tex]
The graph of y= |x| is translated so that the point (1, 1) is moved to (4,1). It means the rule of translation is
[tex](x,y)\rightarrow (x+3,y)[/tex]
it means the graph of y=|x| translated 3 units right. So, the new vertex of the function is (3,0).
The vertex form of an absolute function is
[tex]y=|x-h|+k[/tex]
The new vertex of the function is (3,0). Substitute h=3 and k=0 in the above equation.
[tex]y=|x-3|+0[/tex]
[tex]y=|x-3|[/tex]
Therefore, the required equation is y=|x-3|.
