Ken drew a pair of intersecting rays and marked the angle between them.Which of these statements best compares the pair of intersecting rays with the angle?

A.The rays and the angle have two endpoints each.
B.The rays have a number of points lying on them, and the angle has only one point lying on it.
C. The rays extend infinitely, and the angle is made by the rays which have a common endpoint.
D. The rays and the angle have their lines extending in opposite directions.

Answers

Answer:

C. The rays extend infinitely, and the angle is made by the rays which have a common endpoint

Step-by-step explanation:

We are given that Ken had drawn a pair of intersecting rays and have marked the angles between them.

As we know that a ray is a line segment which has one end point and is extended infinitely in one direction.

Moreover, an angle is a figure that is formed by the intersection of two rays which have a common end point.

Now according to the options, we see that in,

A. A ray cannot have two end points.

B. A ray extends infinitely, so having a number of points is not possible.

D. An angle cannot have a line.

So, we see that all the options except C are discarded.

Hence, option C is the best option that compares the pair of intersecting rays with the angle.

Answer: C. The rays extend infinitely, and the angle is made by the rays which have a common endpoint

Step-by-step explanation:

Given: Ken had drawn a pair of intersecting rays and have marked the angles between them.

The definition of angle says that an angle is a shape that is produced by the intersection of two rays that have a common end point.

A ray is a line segment that has only one end point and is extended infinitely in a unique direction .

According to the above definitions , the correct option is C "The rays extend infinitely, and the angle is made by the rays which have a common endpoint.".

Martha Owens is paid $14.50per hour for a regular forty-hour work
week. Her overtime pay is one-and-one-
half times her regular hourly rate. This
past week Martha earned S754.00 in total
рау. .
How many hours of overtime did
Martha work this pas week?

Answers

Martha worked approximately 8 hours of overtime during the past week.

Martha's regular hourly rate is $14.50, and she works a regular forty-hour work week. Her overtime pay is one-and-one-half times her regular hourly rate.

Let's break down Martha's earnings for the week:

Regular Earnings (for 40 hours): Regular Hourly Rate × Hours Worked

Regular Earnings = $14.50 × 40 = $580

Total Earnings (including overtime): $754

Overtime Earnings = Total Earnings - Regular Earnings

Overtime Earnings = $754 - $580 = $174

Since Martha's overtime pay is one-and-one-half times her regular hourly rate, we can set up an equation:

Overtime Earnings = Overtime Hourly Rate × Hours of Overtime Worked

Solving for Hours of Overtime Worked:

Hours of Overtime Worked = Overtime Earnings / Overtime Hourly Rate

Overtime Hourly Rate = 1.5 × Regular Hourly Rate

Overtime Hourly Rate = 1.5 × $14.50 = $21.75

Now, plug in the values:

Hours of Overtime Worked = $174 / $21.75 ≈ 8

Martha worked approximately 8 hours of overtime during the past week.

Answer:

Step-by-step explanation:

14.50*40=580 for reg pay

754-580=174 over time

14.50*1.5=21.75 an hour for ot

174/21.75=8 hours of overtime

A polynomial has one root that equals 5-7i. Name one other root of this polynomial

Answers

Answer:

The other root of the polynomial is 5+7i.

Step-by-step explanation:

According to the complex conjugate root theorem, if a complex number is a root of a polynomial, then its conjugate is also a root of that polynomial.

It means, if a+ib is a complex root of a polynomial, then its conjugate a-ib is also the root of that polynomial.

It is given that the a polynomial has one root that equals 5-7i.

To find the conjugate of a complex number the sign of imaginary part is changed.

The conjugate of 5-7i is 5+7i.

A polynomial has one root that equals 5-7i, using complex conjugate root theorem 5+7i is the other root of this polynomial.

Answer:

The other root is 5 + 7i.

The volume of a solid right pyramid with a square base is v units3 and the length of the base edge is y units. which expression represents the height of the pyramid? units (3v – y2) units (v – 3y2) units units

Answers

we know that

The volume of a solid right pyramid with a square base is equal to

$V=(1)/(3)*[ area\ of\ the\ base]*height$

area of the base is the area of a square

$area\ of\ the\ base=y^(2)\ units^(2)\nV=v\ units^(3)$

Substitute the values in the formula of volume

$v=(1)/(3)*[ y^(2)]*height$

solve for the height

$v=(1)/(3)*[ y^(2)]*height\n \nheight=(3v)/(y^(2))\ units$

therefore

the answer is

$height=(3v)/(y^(2))\ units$

3v/y² units

Further explanation

Given:

The volume of a solid right pyramid with a square base is v units³
The length of the base edge is y units.

Question:

Which an expression represents the height of the pyramid?

The Process:

We will solve the problem of a geometric solid.

Let us recall the formula of volume of a right pyramid:

$\boxed{ \ V = (1)/(3) * base \ area * height \ }$

Because the base is square, we use the formula for square area, i.e., side times side.

Let us find out the height of the pyramid.

$\boxed{ \ Height = (3v)/(y * y) \ }$

Thus, an expression represents the height of the pyramid is $\boxed{\boxed{ \ (3v)/(y^2) \ }}$ units

josh wanted to buy a bicycle but didn't have enough money. After josh told his troubles to sam slick, sam said,"I can fix that. see that fence? each time you jump that fence, i'll double your money. There's one small thing though: you must give me $32 each time for the priviledge of jumping." Josh agreed, jumped the fence, received his payment from sam slick, and paid sam $32. Repeating the routine twice more, josh was distressed to find that, on the last jump,after sam had made his payment to josh, josh had only $32, with which to pay sam and so had nothing left. Sam, of course, went merrily on his way, leaving josh wishing that he had known a little more about mathematics.
