En una tienda en la que todo está rebajado el 20% he comprado una casaca por la que he pagado 160 soles. ¿Cuál era el precio antes de la rebaja?
Answer:
200 soles
Step-by-step explanation:
De la pregunta anterior, se nos da un descuento del 20%.
Por lo tanto, la fórmula para resolver la pregunta anterior es:
Precio nuevo = Precio inicial - (Porcentaje de descuento × Precio inicial)
De la pregunta anterior,
Precio nuevo = 160 soles
Precio inicial = x
Porcentaje de descuento = 20% = 0.2
Por eso:
160 = x - (20% x x)
160 = x - 0.2x
160 = 0.8 veces
Dividir ambos lados por 0.8
160 / 0.8 = 0.8 / 0.8
x = 160 / 0.8
x = 200 soles
Por lo tanto, el Precio Inicial que es el precio antes de la venta es de 200 soles.

The first triangle is dilated to form the second triangle. What is the scale factor? Please show your math work step by step.
Answer:
2.5 is the scale factor
Step-by-step explanation:
Skills needed: Identifying the Scale Factor, Division
1) First, we need to understand what the scale factor is.
A scale factor is the value being multiplied by one side of a figure to form another figure that is bigger or smaller. For example:
Let's say you are given a triangle with side lengths 3 cm, 4 cm, and 5 cm and you are supposed to find the side lengths of a new triangle when the scale factor being used is 2. Here, you would multiply all the sides by the value 2. So, the 3 sides are:3 x 2, 4 x 2, and 5 x 2 ---> 6 cm, 8 cm, 10 cm.
2) So to find the scale factor in a problem, you would do the side of one triangle divided the corresponding side of the other triangle.
So to find the scale factor in the above problem (if we were only given side lengths 3 cm, 4 cm, and 5cm & also 6 cm, 8 cm, and 10 cm), you would do:
[tex]\frac{6}{3}[/tex] or [tex]\frac{8}{4}[/tex] or [tex]\frac{10}{5}[/tex], all of which equal 2.
3) So in this problem, you would simply do [tex]\frac{10}{4}[/tex], since 10 and 4 are corresponding sides of dilated triangles.
This is [tex]\frac{5}{2}[/tex] when simplified, or 2.5 as a decimal, since scale factors are usually expressed as decimals.
Hope this helps and have a nice day!! :) :] :D

Given that OA = 2x + 9y, OB = 4x + 8y and CD = 4x - 2y, explain the geometrical relationships between the straight lines AB and CD.
Answer:
The geometrical relationships between the straight lines AB and CD is that they have the same slope
Step-by-step explanation:
Given
[tex]OA = 2x + 9y[/tex]
[tex]OB = 4x + 8y[/tex]
[tex]CD = 4x - 2y[/tex]
Required
The relationship between AB, CD
Since AB is a straight line and O is the origin, then:
[tex]AB = (c - a)x + (d - b)y[/tex]
Where:
[tex]OA = ax + by[/tex] ====> [tex]OA = 2x + 9y[/tex]
[tex]OB = cx + dy[/tex] ====> [tex]OB = 4x + 8y[/tex]
This implies that:
[tex]a =2[/tex] [tex]b = 9[/tex] [tex]c = 4[/tex] [tex]d = 8[/tex]
So:
[tex]AB = (c - a)x + (d - b)y[/tex]
[tex]AB = (4 - 2)x + (8 - 9)y[/tex]
[tex]AB = 2x -y[/tex]
So, we have:
[tex]AB = 2x -y[/tex]
[tex]CD = 4x - 2y[/tex]
Calculate the slope (m) of [tex]AB\ and\ CD[/tex]
[tex]m = \frac{Coefficient\ of\ y}{Coefficient\ of\ y}[/tex]
For AB
[tex]m_1 = \frac{-1}{2}[/tex]
[tex]m_1 = -\frac{1}{2}[/tex]
For CD
[tex]m_2 = \frac{-2}{4}[/tex]
[tex]m_2 = \frac{-1}{2}[/tex]
[tex]m_2 = -\frac{1}{2}[/tex]
By comparison:
[tex]m_1 = m_2 = -\frac{1}{2}[/tex]
This implies that both lines have the same slope

A bag contains:
• 2 white marbles
3 brown marbles
4 purple marbles
• 6 orange marbles
A marble will be drawn from the bag and replaced 75 times. What is a reasonable prediction for the number of times a brown or purple marble
will be drawn?
50
45
35
30
th
Answer:
45
Step-by-step explanation:
There are 45 total marbles. The probability of drawing a yellow marble on the first draw is 3/4. Given replacement, the probability on the second draw is the same as on the first draw, so the probability of black marble on the second draw is 6/14. The probability of drawing first a yellow marble then a black marble is 3/14 * 6/14 = 18/196.

What is –36° converted to radians?
Answer:
- [tex]\frac{\pi }{5}[/tex] radians
Step-by-step explanation:
To convert from degrees to radians
radian measure = degree measure × [tex]\frac{\pi }{180}[/tex] , then
radian measure = - 36° × [tex]\frac{\pi }{180}[/tex] ( divide 36 and 180 by 36 )
= - [tex]\frac{\pi }{5}[/tex]

King Kyle orders the construction of his future mausoleum (a fancy tomb) so that people never forget his awesomeness. His architect draws a floor plan depicting the mausoleum as a rectangle measuring 35 m 35 m35, start text, space, m, end text by 40 m 40 m40, start text, space, m, end text.
Answer:
14×16
Step-by-step explanation:
The plan of the mausoleum measures 35 metres (width) by 40 metres. It is 2.5 m per square. When redecorating the grave on the grid, 14 (width) by 16 (height) squares should be counted.

Insert 16 rational numbers between 2.1 and 2.2
Answer:
We will apply the formula of d=y- x/n+1
Let y be 2.2 and x be 2.1 and n= 16
Then 2.2-2.1/ 16+1
0.1/17
x+d= 2.1 + 0.1 = 2.2
x+2d= 2.1+2×0.1=2.3
x+3d= 2.1+3×0.1=2.4
x+4d= 2.1+4×0.1=2.5
x+5d=2.1+5×0.1=2.6
x+6d=2.1+6×0.1=2.7

We always follow these rules when we are Multiplying and Dividing numbers with Scientific Notation.
1. If the numbers are not in scientific notation, convert them.
2. Regroup the numbers using the commutative and associative properties of exponents.
3. Now multiply the two numbers written in scientific notation, you work out the coefficients and the exponents separately.
-Use the product rule; aⁿ × aᵇ = a⁽ⁿ⁺ᵇ⁾ to multiply the bases.
4. If the product of the coefficients is greater than 9, convert it to scientific notation and multiply by the new power of 10.
5. Join the new coefficient to the new power of 10 to get the answer.
--------------------------------------------------------------------------------------------------------------
Let's start!
Our equation:
(5.2 × 10⁶)(7 × 10⁸)
--------------------------------------------------------------------------------------------------------------
1. If the numbers are not in scientific notation, convert them.
They are in scientific notation, so we go on to step 2.
2. Regroup the numbers using the commutative and associative properties of exponents.
(5.2 × 7)(10⁶ × 10⁸)
3. Now multiply the two numbers written in scientific notation, you work out the coefficients and the exponents separately.
-Use the product rule; aⁿ × aᵇ = a⁽ⁿ⁺ᵇ⁾ to multiply the bases.
5.2 × 7 = 36.4
10⁶ × 10⁸= 10⁽⁶⁺⁸⁾ = 10¹⁴
4. If the product of the coefficients is greater than 9, convert it to scientific notation and multiply by the new power of 10.
36.4 = 3.64 × 10¹
5. Join the new coefficient to the new power of 10 to get the answer.
3.64 × 10¹ × 10¹⁴
3.64 × 10⁽¹⁺¹⁴⁾ = 3.64 × 10¹⁵
==================================================================
3.64 × 10¹⁵
