ABC and CBD form a linear pair and have equal measures. Tell if ABC is acute, right, or obtuse

Answers

Answer 1
to form a linear pair means that when added, they equal 180 degrees.
but if they have equal measures....180/2 = 90...then they would both equal 90 degrees.....and 90 degrees is a right angle. 
So ABC and CBD are both right angles
Answer 2

Answer:

Right angle

Step-by-step explanation:

When two lines intersect, a linear pair is formed, two angles being linear pair means the sum of those two angles is 180°.

Now if ∠ABC and ∠CBD for a linear pair,

∴∠ABC + ∠CBD = 180°

also given that ∠ABC and ∠CBD are of equal measure

∴ ∠ABC + ∠ABC = 180°

⇒ ∠ABC = 90° = ∠CBD

∴ ∠ABC is right angle

In 2010, a car was purchased for

Let t be the number of years since 2010. Let y be the value of the car, in dollars.
Write an exponential function showing the relationship between y and t.

Answers

A= P(1+r)^t, where P= initial value, r= interest rate in %, and t = number of years.
However, if there isa decrease in value, the formula becomes:

A= P(1-r)^t and in our case :

A = 30,000(1- 0.24)^t  OR A = 30,000(0.76)^t

The area of the segment of circle 'C' is 353.66 sq. units.

Therefore, option (A) is the correct answer.

What is a segment of a circle?

"It is a region bounded by the chord and the corresponding arc lying between the endpoints of the chord."

Formula to calculate the area of the segment of circle:

[tex]A = (\frac{1}{2} ) \times r^2\times [(\frac{\pi}{180}) \theta - sin \theta][/tex]

where, angle is measured in degree

For given example,

radius r = 24,

angle [tex]\theta[/tex] = 120°

In given diagram, the area of the segment of circle is given by the shaded part.

Using the formula of the area of the segment of the circle,

⇒ [tex]A = (\frac{1}{2} ) \times r^2\times [(\frac{\pi}{180}) \theta - sin \theta][/tex]

⇒ [tex]A = (\frac{1}{2} ) \times (24)^2\times [(\frac{\pi}{180} \times 120) - sin(120)][/tex]

⇒ [tex]A = 288\times [\frac{2\pi}{3} - 0.87][/tex]

⇒ [tex]A=353.66[/tex] sq. units.

Therefore, the area of the segment of circle 'C' is 353.66 sq. units.

Therefore, option (A) is the correct answer.

What is y when x = 60?

Answers

Final Answer:

[tex]\( y \) is the value obtained by substituting \( x = 60 \)[/tex] into the given function.

Explanation:

To determine [tex]\( y \) when \( x = 60 \)[/tex], we need to refer to the specific function or equation provided. This function could be linear, quadratic, exponential, or any other mathematical expression involving [tex]\( x \) and \( y \)[/tex]. Let's consider a hypothetical linear equation [tex]\( y = mx + b \)[/tex] for illustration purposes.

In the case of a linear equation, [tex]\( m \) represents the slope, and \( b \)[/tex] is the y-intercept. When [tex]\( x = 60 \),[/tex] we substitute this value into the equation to find [tex]\( y \). For example, if \( y = 2x + 5 \), then \( y = 2 \times 60 + 5 = 125 \).[/tex] Therefore, the final answer is [tex]\( y = 125 \) when \( x = 60 \)[/tex] in this particular linear equation.

It's crucial to emphasize that the specific nature of the function or equation will dictate the process of finding [tex]\( y \) for a given \( x \).[/tex] This explanation serves as a general guide, and the procedure may vary based on the mathematical form provided. Whether it's a polynomial, trigonometric, or logarithmic function, the fundamental principle remains consistent: substitute the given [tex]\( x \) value to obtain the corresponding \( y \) value.[/tex]

Final Answer:

The value of y when x = 60 + 24y is y = 2.

Explanation:

In the given equation, x = 60 + 24y, we are asked to find the value of y when x is expressed in terms of y. To solve for y, we'll isolate the variable on one side of the equation.

Isolating y:

Subtract 24y from both sides of the equation to collect all y terms on one side:

x - 24y = 60

Solving for y:

Now, isolate y by dividing both sides by -24:

y = 60 / -24

y = -5/2

However, the value of y obtained from the calculation above is not the final answer. We made a mistake in the process of isolating y. Let's correct that:

Correction:

Subtract 24y from both sides correctly:

x - 24y = 60 - 24y

Now, add 24y to both sides:

x = 60

Subtract x from both sides:

-24y = 60 - x

Divide by -24 to isolate y:

y = (60 - x) / -24

Final Answer:

Simplifying the expression further:

y = (x - 60) / 24

Now, we can substitute the given value of x (x = 60 + 24y) back into the equation:

y = (60 + 24y - 60) / 24

y = 24y / 24

y = 1

However, there's one more adjustment needed. We forgot to account for the initial 24y in the expression:

y = 1 + 1

y = 2

Therefore, the correct and final answer is y = 2 when x = 60 + 24y.

Write a function rule for the area of a rectangle whose length is 6 ft more than its width. What is the area of the rectangle when its width is 12 ​ft?

Answers

Let x be the width.
=> x+6 will be the length.
Function: x(x+6)= x^2+6x

Area= 12^2+6.12= 216 ft

The area of the rectangle is 72 square ft and this can be determined by using the formula of the area of the rectangle.

Given :

Length is 6 ft more than its width.

The following steps can be used in order to determine the area of the rectangle when its width is 12 ​ft:

Step 1 - Let the length of the rectangle be 'L' and the width of the rectangle be 'W'.

Step 2 - According to the given data, length is 6 ft more than its width that is:

L = 6 + W

Step 3 - The formula of the area of the rectangle is given below:

A = LW

Step 4 - Substitute the value of 'L' in the above expression.

A = (6 + W)W

Step 5 - Now, at W = 6ft the area of the rectangle becomes:

A = (6 + 6)6

A = 72 square ft.

Then these are the possible dimensions:

x         y               area = x * y
feet    feet            feet^2

1        180            1 * 180 = 180

2        90              2 * 90 = 180

5x^2-40=0; solve by using square roots.

Answers

Final answer:

To solve the equation 5x^2-40=0 using square roots, start by isolating x^2, divide by 5 and then apply the square root. The solutions are x = 2√2 and x = -2√2.

Explanation:

To solve the equation 5x^2-40=0 using square roots, we can start by isolating x^2 by adding 40 to both sides of the equation, resulting in 5x^2 = 40. Next, divide both sides of the equation by 5 to get x^2 = 8. Now, we can take the square root of both sides to solve for x. Since the solution involves a square root, we need to include both the positive and negative square root:

x = ±√8

Simplifying the square root of 8, we have:

x = ±√(4*2)

x = ±√4 * √2

x = ±2 * √2

So, the solutions to the equation 5x^2-40=0 are x = 2√2 and x = -2√2.

how to find the factor of a trinomial?

I can tell you about the 'ac' method of factoring trinomials by way of an example:-

Now we need to find  2 factors of -45 which will when added give - 4 ( the coefficient of x)

-9 and = 5  look like the  ones so we write

3x^2 - 9x + 5x - 15

 Now  factor this by grouping:-

Answers

we know that

the corresponding angles are congruent

so

m∠Q=m∠J

m∠R=m∠K

m∠S=m∠L

we have

m∠J=[tex]37\°[/tex]

therefore

the answer is

m∠Q=[tex]37\°[/tex]


Answer:

m∠Q = 37°

Step-by-step explanation:

It has been given that ΔJKL ≅ ΔQRS

∠J = 37° and ∠K = 105°

Since these triangles are congruent so we will apply the condition of ASA (theorem of congruence)

In ΔJKL and ΔQRS sides JK and QR along with their corresponding angles will be equal.

Side JK = side QR

and ∠K = ∠R = 105°

∠J = ∠Q = 37°

Therefore m∠Q = 37° will be the answer.

Mary gets an annual salary of $56,780. if she is paid semimonthly, what is the amount of her semimonthly gross pay?

Answers

 There are 52 weeks in a year. Being paid biweekly means being paid every other week, or 26 times a year. 

$567.20 * 26 

There are 12 months in a year. If Mary is paid semimonthly, she is paid twice a month, or 24 times a year. 

$56,780 / 24

Mary gets paid $2,365.83 on a semimonthly period basis.

Mary gets around $56,780 per year.

To answer this question, you need to divide the annual salary by the number of semimonthly periods we have in a year.

There are 12 monthly periods. Semi means half so a month has 2 semi periods.

The number of semimonths in a year are:

= 12 months x 2

= 24 semimonths

Mary's semimonthly pay is therefore:

= Annual salary / Number of semimonthly periods

= 56,780 / 24

= $2,365.83

In conclusion, Mary's semimonthly pay is $2,365.83.
