The perimeter of a rectangle is 36 inches, and the area is 65 square inches. find the length and width of the rectangle.
Answers
Perimeter = (2 x Length) + (2 x Width)Width = [Perimeter - (2 x Length)]/2= [36 -(2 x 13)]/2= (36 - 26)/2= 10/2= 5 inches
Area = Length x Width= 13 x 5 = 65 square inches

What is the relationship between the sine and cosine of complementary angles in a right triangle? Please give an example to support your answer.
Answers
Let [tex]m(\angle A)=\alpha[/tex], and [tex]m(\angle B)=\beta[/tex].
[tex]\alpha +\beta=90^{\circ}[/tex], so angles A and B are complementary.
According to the definition of sine, and cosine:
[tex]\displaystyle{ \sin \alpha= \frac{opposite\ side}{hypotenuse} =\frac{a}{c} [/tex], and
[tex]\displaystyle{ \cos \beta= \frac{adjacent\ side}{hypotenuse} =\frac{a}{c} [/tex]
Answer: they are equal.
Final answer:
The sine and cosine of complementary angles in a right triangle are equal to each other but reversed, because the opposite side for one angle is the adjacent side for the other, relative to the hypotenuse.
Explanation:
The relationship between the sine and cosine of complementary angles in a right triangle is that they are equal to each other but reversed. If one angle is x and its complementary angle is 90° - x (because complementary angles add up to 90°), then the sine of x is equal to the cosine of its complementary angle, and vice versa.
This is because, in a right triangle, the side that is the opposite side for one angle becomes the adjacent side for the complementary angle, relative to the hypotenuse which remains the same for both angles.
For example, in a right triangle with one acute angle of 30°, its complementary angle is 60°. The sine of 30° is 1/2, and the cosine of 60° is also 1/2. Similarly, the cosine of 30° is [tex]\sqrt{3/2[/tex], and the sine of 60° is [tex]\sqrt{3/2[/tex] shows a complementary relationship.

Answers
[tex] \frac{3}{y-2} =8[/tex]
Multiply each side by (y - 2).
[tex](y-2).( \frac{3}{y-2)}) = 8(y-2) [/tex]
Note that (y-2) in the numerator and denominator cancel out on the left side.
Therefore
3 = 8(y - 2)
3 = 8y - 16
Add 16 to each side.
3 + 16 = 8y - 16 + 16
19 = 8y
Divideach side by 8.
19/8 = y
Answer: [tex]y= \frac{19}{8} [/tex]

I will do the first one only. The second question is done the same way.
Replace every x you see in the function with 2b and do the math.
f(x) = x^2 + 2x + 1
Let x = 2b
f(2b) = (2b)^2 + 2(2b) + 1
f(2b) = 4b^2 + 4b + 1

Answer:
[tex]\text{The quotient is }2x^2+4x+6[/tex]
Step-by-step explanation:
Given the dividend and divisor we have to find the remainder using synthetic division.
The given polynomial [tex]2x^3-2x-12[/tex] is divided by (x-2).
Step 1: Set up the synthetic division.
The dividend goes on the inside of the box.
Step 2: Bring down the leading coefficient to the bottom row.
Step 3: Multiply c i.e 2 by the value just written on the bottom row.
Step 4: Add the column created in step 3 and write the sum in the bottom row.
Repeat steps 1-4 until the last column.
From the last row the remainder becomes
[tex]2x^2+4x+6[/tex]
Hence, option A is correct.

In 2 years Jim will be 8 and Harry will be 4 which is twice as much Harry's age.
hope this helps!
Answer: The present age of Harry is 2 years and that of Jim is 6 years.
Step-by-step explanation: Given that in 4 years, Harry’s age will be the same as Jim’s age is now. In 2 years, Jim will be twice as old as Harry will be.
We are to find the present ages of Harry and Jim.
Let x and y represents the present ages of Harry and Jim respectively.
Then, according to the given information, we have
[tex]x+4=y~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\\\\y+2=2(x+2)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)[/tex]
Substituting the value of y from equation (i) in equation (ii), we get
[tex]y+2=2x+4\\\\\Rightarrow x+4+2=2x+4\\\\\Rightarrow 2x-x=2\\\\\Rightarrow x=2.[/tex]
From equation (i), we get
[tex]y=x+4=2+4=6.[/tex]
Thus, the present age of Harry is 2 years and that of Jim is 6 years.

Sally has 42 coins, all dimes and nickels, that have a total value of $3.00. How many nickels does she have?
Answers
Sally has 24 nickels.
Explanation:To determine the number of nickels Sally has, we can set up a system of equations using the given information. Let's assume Sally has x nickels and (42 - x) dimes. The value of the nickels is 5x cents, and the value of the dimes is 10(42 - x) cents. We can set up the equation: 5x + 10(42 - x) = 300 (since the total value is $3.00).
Simplifying the equation, we get: 5x + 420 - 10x = 300. Combining like terms, we have: -5x + 420 = 300. Subtracting 420 from both sides gives us: -5x = -120. Dividing both sides by -5, we find x = 24.
Therefore, Sally has 24 nickels.

The provided statements are either given information, interpretations from the given diagram or applying rules of geometry such as the definitions of supplementary angles and the Same-Side Interior Angles Theorem.
Explanation:The missing reasons in this geometric proof are as follows:
a. Given: The fact that angle 5 = 40 is simply provided, it's the given information in the question.
b. Given: Similarly, the measurement of angle 2 being 140 is given information.
c. Definition of supplementary angles: Angle 5 and angle 2 are supplementary because the sum of their measure equals 180 (40+140).
d. Interpretation of the diagram: Without a diagram, it's difficult to be precise, but if angle 5 and angle 2 are indicated as same-side interior angles, then this inference comes from interpreting the diagram.
e. Same-Side Interior Angles Theorem: Lastly, if the same-side interior angles are supplementary, then the lines are parallel. This is a rule encapsulated by the same-side interior angles theorem.
