The scale factor is always the ratio of new image with respect to the old image.
6) The scale factor as per the image is 3:1 or 3.
7) The New image is P'Q'R'S' and old image is PQRS so the scale factor is given by:

Un establecimiento vendía café a 5€/kg. Si ahora lo vende a 4,75€/kg, obtener el porcentaje de descuento aplicado. Porfavor es para dentro de 1 hora
Answers
El porcentaje del descuento aplicado es del 5%.
¿Como encontrar el porcentaje del descuento aplicado?
Recordar que si aplicamos un descuento de X (sería un porcentaje X) a un precio P, entonces el nuevo precio será:
P' = P(1 - X/100)
En este caso, sabemos que el precio origina es 5€ por kilo, y el precio nuevo es 4.75 € por kilo, reemplazando esos numeros en la ecuación de arriba obtenemos:
4.75 = 5*(1 - X/100%)
4.75/5 = 1 - X/100%
X/100% = 1 - 4.75/5
X = (1 - 4.75/5)*100%
X = 5%
Fue un descuento del 5%.

Answers
The domain of the given situation is 0≤t≤10.
Explain domainThe elements that make up a function are its domain and range. A function's domain is the set of all potential input values, while its range is the range of possible output values. Range, Function, and Domain. If a function f: A B exists that maps each element of A to an element of B, then A is the domain, and B is the co-domain. When (a, b) ∈ R, the image of element 'a' under the relation R is supplied by 'b'.
Given, the average hiking rate is 3 miles per hour.
The number of hours you plan hiking for is 10 hours.
Now, as we know that time can't be negative so we know that the domain must have t≥0.
And it is given that you plan to hike for 10 hours so the domain must also have t≤10.
Therefore, the domain of the given situation is 0≤t≤10.

Answers
The answer to the Equation (|b-8|=2b) is b = 8/3
Given Equation-
|b-8|=2b
Subtract 2b from both sides
|b-8|-2b = 2b-2b
Now we will simplify it by rearranging and combining like terms
we get,
-2b + |b-8| = 0
split the problem into two cases: one positive and one negative
-2b + b-8 = 0 --eqn 1
-2b - (b-8) = 0 --eqn 2
now solve equation 1 and combine like terms
we get,
-b - 8 = 0
b= -8
equation 2
we get,

Sample Answer: {(1, 2), (3 , 4), (5, 6), ...}
Equation: 2y = 6x - 10
Domain: {-1, 3, 8}
Answers
The solution set of the given equation is {(-1,-8),(3,4),(8,19)}.
Define solution set and domain.The set of ordered pairs that make up the solution to an equation with two variables is referred to as the solution set.
In mathematics, a function's domain is the collection of possible inputs it will accept.
Given equation is 2y = 6x - 10 and domain is {-1, 3, 8}
We can also write the given equation is
y =(6x-10)/2 ------------equation 1
As we know, domain is considered as the value of x,
Consequently, if we enter x = -1 in equation 1, we will receive
y = (-16)/2
y = -8
Similarly put x = 3 in equation 1, we will get
y = 8/2
y = 4
Similarly put x = 8 in equation 1, we will get
y = 38/2
y = 19
By combining the values of x and y, we get
The solution set of the given equation is {(-1,-8),(3,4),(8,19)}.

Suppose the lake by your house as 198,000 gallons. But its volume grew by 3000 every weekWrite an equation modeling the number of gals in the lake after so many weeks
Answers
Given:
The current volume of the lake is 198,000 gallons.
Its volume grew by 3000 gallons every week
To find: An equation modeling the number of gallons in the lake after some weeks.
Explanation:
As we know,
If the growth or decay involves increasing or decreasing by a fixed number, then we must use a linear function.
Here, the increasing rate is 3000.
The current volume is 198,000 gallons.
Thus, the linear function that represents this situation is,
[tex]V=3000w+198000[/tex]Where w represents the number of weeks and V represents the volume.
Final answer:
The equation is,

Padma is covering the top of her square pyramid with gold foil. If there is no overlap, how much foil will she need?Round to the nearest cm2
Answers
Answer: She will need 1239 cm^3 of foil
Explanation:
Surface area of square pyramid = base area of square + area of 4 triangular faces
Area of square base = l^2
where
l is the length of each side of the square base
From the information given,
l = 8
Area of square base = 8^2 = 64
Area of each triangular face = 1/2 x base x height
We would find the height of each face by applying Pythagorean theorem to the right triangle formed below. It is ex[ressed as
hypotenuse^2 = one leg^2 + other leg^2
hypotenuse = 10
one leg = 4
other leg = h
4^2 + h^2 = 10^2
36 + h^2 = 100
h^2 = 100 - 36 = 64
h = √64
h = 8
base = 8
Area of 4 triangular faces 4 x 1/2 x 8 x 8 = 128
Surface area of square base pyramid = 128 + 64 = 192 in^2
We would convert 192 in^2 cm^2
Recall,
1 inch^2 = 6,4516 cm^2
192 inch^2 = 192 x 6.4516
= 1239 cm^2
She will need 1239 cm^3 of foil
A pair of supplementary angles are in the ratio 4:5.Find the complement of smaller angle .
Answers
The complement of the smaller angle of supplementary angles in ratio 4:5 is given by 10 degree.
Given that the supplementary angles are in ratio 4:5.
Let the angles be 4x and 5x respectively.
We know that the sum of supplementary angles is 180 degree.
So, 4x+5x = 180
9x = 180
x = 180/9
x = 20
So the angles are = (20*4),(20*5) = 80,100.
So the smaller angle is 80 degree.
