Answer:

3

Step-by-step explanation:

You have a 1 in 6 chance to roll a two. This means that every six times you roll a dice 1 of those should be a two (Obviously in the real world this wouldn't happen)

You roll the dice 18 TIMES and your chances are 1 in 6 so you take

18 \times  \frac{1}{6}

If a condominium is purchased for Php 5,700,000.00 and the bank requires 30% down payment, how much is the mortgaged amount?
Darya [45]

We are given that the condominium cost Php 5,700,000.00 and a down payment was made. Since the down payment was 30% of the total cost, therefore we can conclude that the mortgage amount is 70% of the total cost. Hence:

70% = 0.70

 

mortgage amount = 5,700,000.00 * 0.70

mortgage amount = 3,990,000.00

 

Answer:

<span>Php 3,990,000.00</span>

Which transformation of AB will produce a line segment A'B' that is parallel to AB?
lyudmila [28]

<em>Options:</em>

<em>Rotation of 180° about point B </em>

<em>Rotation of 90° about point b </em>

<em>Reflection over the x-axis </em>

<em>Translation down 2 units</em>

<em></em>

Answer:

Rotation of 180° about point B

<em></em>

Step-by-step explanation:

Considering coordinates of point B

Assume the coordinates of the line at point B is (x,y)

i.e. B = (x,y)

First, we need to determine the slope at point B

Taking coordinates about the origin.

The slope of B is:

m = \frac{y_2 - y_1}{x_2 - x_1}

Where

(x_1,y_1) = (0,0) --- origin

(x_2,y_2) = (x,y)

m = \frac{y_2 - y_1}{x_2 - x_1} becomes

m = \frac{y - 0}{x - 0}

m = \frac{y}{x}

Taking the options one after the other:

Option A.

When rotated by 180°, the resulting coordinates of B would be

B' = (-x,-y)

Taking the slope of B'

The slope of B is:

m = \frac{y_2 - y_1}{x_2 - x_1}

Where

(x_1,y_1) = (0,0) --- origin

(x_2,y_2) = (-x,-y)

m = \frac{y_2 - y_1}{x_2 - x_1} becomes

m = \frac{-y - 0}{-x - 0}

m = \frac{-y}{-x}

m = \frac{y}{x}

Notice that the slope of B and B' is the same;

m = \frac{y}{x}

<em>Hence:</em>

<em>Rotation of 180° about point B  answers the question</em>

<em></em>

<em>There's no need to check for other options</em>

Answer:

127/20

Step-by-step explanation:

4×(20/20) + (3/4)×(5/5) + (8/5)×(4/4)

= (80/20) + (15/20) + (32/20)

= 127/20

4 is divided by the difference of 7 and a number.
love history [14]

The mathematical expression that represents the given statement is 4/(7-x)

<h3>Writing an Expression </h3>

From the question, we are to write a mathematical expression for the given statement

The given statement is

"4 is divided by the difference of 7 and a number."

First,

Let the number be x

"the difference of 7 and a number" means

7 - x

Thus,

"4 is divided by the difference of 7 and a number" is

4/(7-x)

Hence, the mathematical expression that represents the given statement is 4/(7-x)
