Answer:

(a) Kaylee earns $19.50 per hour.

(b) Kaylee earns more money per hour than Joey.

Step-by-step explanation:

x = # of hrs. worked

y = amount of money earned

Joey:

y = 16.50x

Kaylee:

Time (h) 2, 5, 8, 10

Money earned ($) 39, 97.50, 156, 195

y = mx + b; Slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

We will be using: (2,39) and (8,156) to find the slope of this table.

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{156-39}{8-2} \\\\m=\frac{117}{6} \\\\m=19.5[/tex]

y = mx + b

y = 19.5x + b

I will be using (2, 39) to find the value of b

(2, 39)

y = 19.5x + b

39 = 19.5(2) + b

39 = 39 + b

-39  -39

0 = b

y = 19.5x + b ==> y = 17.7x + 0 =  OR  y = 19.5x (since the value of b is 0)

(a) The question wants us to find out how money Kaylee earns per hour. Recall that x = # of hrs. worked and y = amount of money earned.

y = 19.5x

She earns $19.50 per hour.

(b)

Joey: y = 16.50x (earns $16.50 per hour)

Kaylee: y = 19.5x (earns $19.50 per hour)

As you can see, Kaylee earns more money per hour than Joey.

Hope this helps!

Answer:

the answer is B for the question

The measure of chord XY in the given circle is 10.2 units.

The chord of a circle is defined as the line segment joining any two points on the circumference of the circle. It should be noted that the diameter is the longest chord of a circle that passes through the center of the circle.

Given that a circle, O, where, arcs, XY and XZ are congruent,

We need to find the measure of chord XY in the given circle.

Since, we know that,

If two chord are of the same length, then the two arcs they intercept are congruent.

Therefore,

Arc XY = Arc XZ

Therefore,

XY = 10.2 units

Hence, the measure of chord XY in the given circle is 10.2 units. in a

Step-by-step explanation:

Pamela will be 1.7 miles if she walks one-tenth of a mile toward camp.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

At the 1.8-mile marker, Pamela stopped.

We have to determine the mile toward camp if she makes it a mile and a tenth of the way to camp.

Since a tenth of a mile is equal to one mile, if she is heading in the direction of the camp and the 1.8-mile marker is moving forward.

As per the given condition,

So remaining distance would be

⇒ 1.8 - (1/10)

⇒ 1.8 - 0.10

⇒ 1.7

Therefore, she will be 1.7 miles if she walks one-tenth of a mile toward camp.

Answer:

x = 30 degrees

y = 67 degrees

z = 83 degrees

Step-by-step explanation:

Let's first set up a few equations. We know:

x + y + z = 180

y + z = 5x

z = y + 16

Let's now solve our equations through substitution. We'll substitute variable z in equations one and two for (y + 16), which is possible thanks to our third equation.

Now, our second equation has become:

y + y + 16 = 5x

So...

5x = 2y + 16

Our first equation is now:

x + y + y + 16 = 180

So...

x + 2y = 180 - 16

And...

x + 2y = 164

Finally...

x = 164 - 2y

Let's take a look at our new first and second equations:

5x = 2y + 16

x = 164 - 2y

Let's substitute again, replacing x in the first equation with (164 - 2y).

Our first equation is now the following:

5(164 - 2y) = 2y + 16

We can apply the Distributive Property to get:

820 - 10y = 2y + 16

So...

-10y - 2y = 16 - 820

-12y = -804

y = 67

Now that we have found y, we can find x and z.

We know that the third angle z is 16 more than the second, y. That was our third equation, z = y + 16.

So, z = 67 + 16.

z = 83.

We know the sum of the y and z is five times the measure of x.

(83 + 67)/5 = 30

To check our work, we can do 67 + 83 + 30 = 180. So we know we are correct.

For the right handed limit we now have x → a + x → a + (note the +) which means that we know will only look at x>a. the left handed limit we have x → a− x → a − (note the -) the means that we will only be looking at x < a
