Answer:

Php 973.00

Step-by-step explanation:

Aling Luz bought 3/8 yards of linen cloth which cost Php 72.00 per yard.She gave Php 1000.00 to the cashier.How much change will she?

Number of yards bought = 3/8

Cost of a yard = Phone 72.00

Cost of number of yards bought = Number of yards bought × Cost of a yard

= 3/8 × Php 72.00

= Php 27.00

She gave Php 1000.00 to the cashier.

How much change will she?

= Amount given to the cashier - cost of yards bought

= Php 1000.00 - Php 27.00

= Php 973.00

Answer:

9/2 or if that doesn't work try 4 1/2

Step-by-step explanation:

The probably of getting a plain pencil from the first box is 9/10. The probability of getting a color pencil from the second box is 5/10. If you multiply those you get 9/2 or 4 1/2.

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:

a) s = 2a sinh(b/a)

b) 18 feet

Step-by-step explanation:

The arc length is:

s = ∫ √(1 + (dy/dx)²) dx

y = a cosh(x/a)

y = ½ a (e^(x/a) + e^(-x/a))

dy/dx = ½ a (1/a e^(x/a) − 1/a e^(-x/a))

dy/dx = ½ (e^(x/a) − e^(-x/a))

(dy/dx)² = ¼ (e^(2x/a) − 2 + e^(-2x/a))

Plugging in:

s = ∫ √(1 + ¼ (e^(2x/a) − 2 + e^(-2x/a))) dx

s = ∫ ½ √(4 + e^(2x/a) − 2 + e^(-2x/a)) dx

s = ∫ ½ √(e^(2x/a) + 2 + e^(-2x/a)) dx

s = ∫ ½ √(e^(x/a) + e^(-x/a))² dx

s = ∫ ½ (e^(x/a) + e^(-x/a)) dx

s = ½ (a e^(x/a) − a e^(-x/a))

s = ½ a (e^(x/a) − e^(-x/a))

Evaluate from x=-b to x=b:

s = ½ a (e^(b/a) − e^(-b/a)) − ½ a (e^(-b/a) − e^(b/a))

s = ½ a e^(b/a) − ½ a e^(-b/a) − ½ a e^(-b/a) + ½ a e^(b/a)

s = a e^(b/a) − a e^(-b/a)

s = a (e^(b/a) − e^(-b/a))

s = 2a sinh(b/a)

We know that s = 48, and b = 20.  We also know y = 30 when x = b.

48 = 2a sinh(20/a)

24 = a sinh(20/a)

30 = a cosh(20/a)

Using the given identity:

cosh²(20/a) − sin²(20/a) = 1

a² cosh²(20/a) − a² sin²(20/a) = a²

30² − 24² = a²

a² = 324

a = 18

Therefore, the wire will be 18 feet above the ground at the lowest point.

I am pretty sure it is a because 2 is half of 4 and 18 is half of 36.

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:

Step-by-step explanation:

A square has 4 right angles, a rhombus doesn't have that property therefore, it is impossible

Answer:

F(m)=50*1.03^m

Step-by-step explanation:

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.

Reflecting the triangle ABC implies that the new position would be a mirror of the previous position

The statement that logically comes next is (c) Translate triangle ABC, so that point A maps to point W

After reflecting the triangle ABC, the next step is to map point A to point W on the coordinate plane.

This is done by translating the triangle ABC i.e. by shifting or moving the triangle ABC so that points A and W would be on the same point

Hence, the statement that logically comes next is (c)

Step-by-step explanation:

The table that shows a constant rate of change of -3 is Table D.

Option D is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The constant rate of change (r):

Take two ordered pairs (a, b) and (c, d)

= (d - b) / (c - a)

Now,

From Table D.

We see that,

r = (-1 - 2) / (-21 + 22) = -3/1 = -3

r = (-4 + 1) / (-20 + 21) = -3/1 = -3

r = (-7 + 4) / (-19 + 20) = -3/1 = -3

Thus,

The table that shows a constant rate of change of -3 is Table D.

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.
