A plumber's old rate is $62 per hour. She
increases her fees by 12%.
What will her new hourly rate be?

Answer: 76.92%

Step-by-step explanation:

To find the percent decrease is simple. First let's find the difference: 65 - 15 which gives you 50. 50/65 * 100 = 76.92%.  Have a good day ;)

The solution is Option A.

The translation of the center of circle is given by ( x , y ) ⟶ ( x - 15 , y + 1 )

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

Given data ,

Let the equation for the circle A be represented as

( x - 7 )² + ( y - 1 )² = 16

Now , the equation is of the form ( x - h )² + ( y - k )² = r²

So , the radius of the circle is 4 and the center of the circle is ( 7 , 1 )

Let the equation for the circle A be represented as

( x + 8 )² + ( y - 2 )² = 16

Now , the equation is of the form ( x - h )² + ( y - k )² = r²

So , the radius of the circle is 4 and the center of the circle is ( -8 , 2 )

So , the translation of circle A to B is given by

( 7 , 1 ) to ( -8 , 2 )

So , the x coordinate is translated by 15 units to left and the y coordinate is translated by 1 unit up

Hence , the translation is given by ( x , y ) ⟶ ( x - 15 , y + 1 )

The measure of angle B is 50 degrees and angle C is 80 degrees.

The angle sum property of a triangle states that the sum of interior angles of a triangle is 180°.

In the given triangle, we can use the concept of triangle angle sum to find the unknown measures.

We know that the sum of the angles in a triangle is always 180 degrees.

Therefore, if we know two angles in a triangle, we can find the third angle by subtracting the sum of those angles from 180.

We are given that angle A is 50 degrees. We are also given that angles B and C are unknown. Therefore,

we can use the following equation to find the measure of angles B and C:

A + B + C = 180

50 + B + C = 180

B + C = 180 - 50

B + C = 130

So the sum of angles B and C is 130 degrees. Therefore, we can't find individual measures of angles B and C.

Alternatively, we can use the property of the angle pair which states that if two parallel lines are intersected by a transversal, the alternate interior angles are congruent.

If we know that angle A and angle B are congruent, we can find the measure of angle B as 50 degrees. As a result, angle C will be 180 - 50 - B = 130-50 = 80 degrees.

Hence, the measure of angle B is 50 degrees and angle C is 80 degrees.

Five rays from common endpoints or vertex form 10 distinct angles.

Angles are constructed when two lines intersect at a point. The measurement of the 'opening' between these two rays is called an 'angle'. The symbol represents it ∠. Angles are usually measured in degrees and radians, which is a measurement of circularity or rotation.

In geometry, an angle is constructed when two rays are joined at their endpoints. These rays are named the sides or arms of the angle.

The arms and the vertex are two primary parts of an angle.

The two rays which converge at a common point to create the angle are called the arms of the angle.

Lance and Alberto cycled along the same 75 km route. Speed of Alberto is 30 km/ hr

Since, Lance takes 3 hours to complete 75km, his speed will be

v= [tex]\frac{75}{3}[/tex]

v= 25 km/hr

The amount of time taken by Lance to complete 10 km is

t= 10/25

t =0.4 hr

t= 0,4×60 min

t=24 min.

Since Alberto started 4 min late and  time taken by Alberto to complete 10 km is

t= 24-4

t=20 min.

Hence, speed of Alberto is v=10/0.33

v=30 km/hr.

A measure of how quickly something is moving is speed. The distance an object travels in a single time unit is its speed. The speed formula is: Distance times speed. Meters per second (m/s), kilometres per hour (km/h), and miles per hour (mph) are the most common units of speed.

Speed is calculated by dividing distance by time. You must be familiar with the distance and time units in order to determine the units of speed. The units will be measured in meters per second (m/s) because distance is measured in meters (m) and time is measured in seconds (s).

For math equation, To eliminate a variable, it must have the same coefficient. So if the coefficients of the variables are not the same then first equate the coefficients by multiplying or dividing them.

Determine the set of solutions to the following system of equations using the elimination method, if x and y are variables in the set of real numbers.

Completion:

1. x + y = 1 and x + 5y = 5

To eliminate the y variable, remember that the coefficients of y must be the same, so the equation x + y = 1 times 5 and the equation x + 5y = 5 times 1, then:

x + y = 1     │× 5 => 5x + 5y = 5

x + 5y = 5   │× 1 => x + 5y = 5

5x + 5y = 5

x + 5y = 5

--------------- –

4x + 0 = 0

The solution of equation 3x + 4y = -12 for y is y = -3 - 3/4 x.

In the given question, we have to solve 3x + 4y = -12 for y.

The given equation is 3x + 4y = -12.

To solve this equation for y, we have to isolate the y.

Now solving the given equation.

3x + 4y = -12

Subtract 3x on both side, we get

4y = -12 - 3x

Divide by 4 on both side, we get

y = [tex]\frac{1}{4}[/tex](-12 - 3x)

Answer: 1/8

Step-by-step explanation:

After solving, we check that [tex]x^2[/tex] - 1 cannot be the quotient of p(x).

In the given question, we have to check whether the quotient is [tex]x^2[/tex] - 1.

The given polynomial is [tex]x^6 + 2x^3[/tex] + x - 1 is divided by a polynomial in x of degree 5.

Given a polynomial p(x) and a non-zero polynomial g(x), the division algorithm asserts that there are polynomials q(x) and r(x) such that p(x) = g(x) q(x) + r(x), where r(x) = 0 or degree r(x) < degree g(x).

5th degree polynomial because the power of the dividend should equal the degree of the product of the quotient and the divisor.

Degree 1 will result from the division of a degree of polynomial 6 by a degree of polynomials 5 and 6.

From the given question,

P(x) = [tex]x^6 + 2x^3[/tex] + x - 1

g(x) = x in degree of 5

q(x) = x² - 1

So,

[tex]x^6 + 2x^3[/tex] + x - 1 = (x in degree of 5)([tex]x^2[/tex] - 1) + r(x)

[tex]x^6 + 2x^3[/tex] + x - 1 = x in degree of 7

Answer: $ 108.42

Step-by-step explanation: Take 20% of the total.

The average rate of change between 2006 and 2010 is 172.

Average rate is a statistical measure used to compare a set of values or quantities. It is calculated by taking the sum of the values, then dividing by the number of values in the set. Average rate is most often used to measure the average performance of a group, individual, or business over a certain period of time.

The average rate of change between 2006 and 2010 is calculated by taking the difference in the values of the function for the two given years and then dividing it by the difference in the two years.
In this case, the difference in the values of the function for 2006 and 2010 is 1725 - 1037 = 688. The difference in the two years is 2010 - 2006 = 4.
Thus, the average rate of change is 688/4 = 172.
