Answer:
16.8 inches
Step-by-step explanation:
Perimeter =2(length+width) so 2·(5.6+2.8)≈16.8
Answer and Step-by-step explanation:
First, write down what we know.
Length of Rectangle = [tex]5\frac{3}{5}[/tex]
Width = [tex]\frac{Length}{2}[/tex]
2 ways to solve this:
1st way:
If we convert the fraction into a decimal, then we can easily find the width.
[tex]5\frac{3}{5}[/tex] can be solved by making the mixed number into a improper fraction.
Multiply the denominator (5) by the whole number (5), then add the numerator (3). This number is 28. Replace the 3 with the 28, and now we have [tex]\frac{28}{5}[/tex]. This number is equal to 5.6.
Now, we have to divide this number.
5.6 divided by 2 is equal to 2.8.
So, the width is equal to 2.8.
Now, we add the width and length together twice to get the perimeter of the rectangle.
2.8 + 2.8 + 5.6 + 5.6 = 16.8
So, the answer is A. 16.8 inches.
2nd way:
Since we know that the width is half of the length, we can just add the length by itself 3 times, since two of the widths combined will equal the length.
5.6 + 5.6 + 5.6 = 16.8
So, the answer is A. 16.8 inches.

You roll a die three times. What is the probability that you would roll a
two each time?
Answer:
1/216
Step-by-step explanation:
There are 6 sides in a die, and one of those sides is a two.
So, the probability of rolling a two is 1/6.
To find the probability of rolling a two each time, multiply 1/6 by itself three times.
1/6 · 1/6 · 1/6
= 1/216
So, the probability is 1/216

if sin theta = 4/5 and theta is in quadrant 2, the value of cot theta is
Answer:
Cot(theta) = - 0.75 or -3/4
Step-by-step explanation:
The hypotenuse is 5
The y value is 4
We need to find the corresponding x value.
x^2 + y^2 = z^2
X = ?
y = 4
z = 5
x^2 + 4^2 = 5^2
x^2 + 16 = 25
x^2 = 9
Now in this case, you are in quadrant 2, so the x value is - 3
sqrt(x^2) = sqrt(9)
x = - 3
The cot value is the adjacent (x value) / the opposite ( y ) value
Cot(theta) = -3/4
cot(theta) = -0.75
Answer:
cotθ = -3/4
Step-by-step explanation:
Given:
sinθ = 4/5
θ is in Quadrant II, so cosθ < 0
Recall:
cotθ = cosθ/sinθ
cos²θ + sin²θ = 1
Determine cosθ:
cosθ = -√(1-sin²θ) = -√(1-(4/5)²) = -√(1-16/25) = -√(9/25) = -3/5
Determine cotθ:
cotθ = cosθ/sinθ = (-3/5)/(4/5) = (-3/5)(5/4) = -15/20 = -3/4

What it means when a function and its inverse is the same?
Step-by-step explanation:
it means that the graph of the function above y=x must be the mirrored image of the graph under y=x.
it means that the function applied to itself gives x.
f(f(x)) = x
e.g.
f(x) = 5 - x
f(f(x)) = 5 - (5 - x) = 5 - 5 + x = x

A number, X, rounded to 1 decimal place is 3,7
Write down the error interval for x,
Answer:
The error interval for x is:
[3.65,3.74]
Step-by-step explanation:
The number after rounding off is obtained as:
3.7
We know that any of the number below on rounding off the number to the first decimal place will result in 3.7:
3.65 3.66 3.67 3.68 3.69 3.70 3.71 3.72 3.73 3.74
( Because if we have to round off a number present in decimals to n place then if there is a number greater than or equal to 5 at n+1 place then it will result to the one higher digit at nth place on rounding off and won't change the digit if it less than 5 )
Hence, the error interval is:
[3.65,3.74]
Find the measure of angle 1
A. 90 degrees
B. 30 degrees
C. 120 degrees
D. 60 degrees
Answer:
120
Step-by-step explanation:
So there are two ways of doing this.
The easiest, we know that the biggest of 30, 60 and 90 degrees is 90.
We know that a right angle is 90 degrees.
The 1 angle is clearly bigger than 90 degrees.
So it must be 120.
The actual way of solving:
The mini trinalge that has the 90 degree angle in it is a 30, 60, 90 trinalge.
We know that the 3 is the 30 degree angle on the trinalge.
We know that the angle on the opposite side of the dotted line must be 30 as well.
Since thats 30, the opposite side of the dotted part of thr traingle must be 30 as well.
This means that the other two angles are 60 which you subtract from 180
This leaves 120
So 120 degree angle is the answer

In ΔWXY, w = 470 inches, mm∠W=55° and mm∠X=42°. Find the length of y, to the nearest 10th of an inch.
The length of y using sine rule is 6664.2 inches
What is sine rule?The sine rule states that if a, b and c are the lengths of the sides of a triangle, and A, B and C are the angles in the triangle; with A opposite a, etc., then a/sinA=b/sinB=c/sinC.
in this case w/sinW = y/sinY
Y = 180-(55+42)
Y = 180-(97)
Y = 83°
Therefore 470/sin55 = y/sin83
470× sin83 = y sin55
= 466.50 = 0.707y
divide both sides by 0.707
y = 466.50/0.707
y = 6664.2 inches

Start with a circle whose equation is (x-a)^2 + (y-b)^2=r. Dilate that circle by a scale factor of 1/r with center of dilation (a,b). What does this transformation demonstrate
The dilation of the circle with a scale factor 1/r and center at (a,b) will transform the circle into a point at (a,b).
A dilation is a transformation that results in an image with the same shape as the original but a different size. • An enlargement is a dilation that produces a larger image. • A reduction is a dilation that produces a smaller image.
To solve this we will use the transformation formula for a dilation with center (a,b) and scale factor
k, (x,y) --> (a + k(x-a), b + k(y-b)).
Substituting in our values, we get
(x,y) --> (a + (1/r)(x-a), b + (1/r)(y-b)).
Setting this equal to (a,b), we get
(a + (1/r)(x-a) = a, b + (1/r)(y-b) = b).
Solving for x and y gives x = a and y = b. Therefore, the dilation of the circle with a scale factor of 1/r and center at (a,b) will transform the circle into a point at (a,b).
