Answer:
SA = 90 in²
Step-by-step explanation:
given 2 similar shapes with sides in ratio a : b , then
ratio of areas = a² : b²
ratio of volumes = a³ : b³
Given ratio of volumes = 64 : 27 , then
ratio of sides = [tex]\sqrt[3]{64}[/tex] : [tex]\sqrt[3]{27}[/tex] = 4 : 3
then ratio of areas = 4² : 3² = 16 : 9
let x be the surface area of the smaller box then by proportion
[tex]\frac{x}{9}[/tex] = [tex]\frac{160}{16}[/tex] = 10 ( multiply both sides by 9 )
x = 90
surface area of smaller box is 90 in²
67.5 square inches is the surface area of a similar shoe box if its volume is only 27 cubic inches
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Given that shoe box has a volume of 64 cubic inches and a surface area of 160 square inches.
We have to find the surface area of a similar shoe box if its volume is only 27 cubic inches
Lets form a proportional equation
64/160 = 27/x
Apply cross multiplication
64x=160(27)
64x=4320
Divide both sides by 64
x=4320/64
x=67.5
Hence, 67.5 square inches is the surface area of a similar shoe box if its volume is only 27 cubic inches

Can any one please help me under this? I need to know which option indicates that 3 goes after 5and between 7,12and 5 then how that goes before 12 and between7 and 3. I’ve been reading this forever and I don’t understand her wording. Help please! Ayuda porfavor!
"3 va después de 5 y entre 7 y 12" = "3 goes after 5, and between 7 and 12"
This eliminates A and D (3 is not between 7 and 12 in either choice).
"5 va antes de 12 y entre 7 y 3" = "5 goes after 12, and between 7 and 3"
This eliminates C (5 is not between 7 and 3).

Two similar squares have matching sides whose lengths are in the ratio 7:5 Find the ratio of their areas.
Answer:
49:25
Step-by-step explanation:
When you have a side length ratio given, the area ratio will be the side length ratio squared.
This can be thought of quite easily, say you have 1 square with a side length of 7 and another square with a sidelength 5.
Of course the squares have a side length ratio of 7:5
The area of the first square is 7*7 = 49
The area of the second square is 5*5 = 25
Then clearly the ratio of the areas is 49:25

Answer:
[tex]g(x)=\dfrac{1}{2}|x-4|+7[/tex]
Step-by-step explanation:
Translations
For [tex]a > 0[/tex]
[tex]f(x-a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units right}[/tex]
[tex]f(x)+a \implies f(x) \: \textsf{translated}\:a\:\textsf{units up}[/tex]
[tex]y=a\:f(x) \implies f(x) \: \textsf{stretched parallel to the y-axis by a factor of}\:a[/tex]
-----------------------------------------------------------------------------------------
Parent function: [tex]f(x)=|x|[/tex]
(with vertex at the origin)
From inspection of the graph, the vertex of the transformed function is at (4, 7). Therefore, there has been a translation of:
4 units right7 units up[tex]\implies f(x-4)+7=|x-4|+7[/tex]
From inspection of the graph, we can see that it has been stretched parallel to the y-axis:
[tex]\implies a\:f(x-4)+7=a|x-4|+7[/tex]
The line goes through point (0, 9)
Substituting this point into the above equation to find [tex]a[/tex]:
[tex]\implies a|0-4|+7=9[/tex]
[tex]\implies 4a=2[/tex]
[tex]\implies a= \dfrac{1}{2}[/tex]
Therefore,

The price of petrol goes up 10%, by how much percent must a motorist reduce the consumption of petrol so that the expenditure on it remains unchanged ?
[tex]\large{\sf \boxed{ \sf 9.09 \ \%}}[/tex]
Explanation:
Let the price be p,
When the price is increased by 10%,
Increased price = (100% + 10%) × p = 1.1p
So reduction percentage:
[tex]\rightarrow \sf \dfrac{1.1p - p}{1.1p} \ x \ 100[/tex]
[tex]\rightarrow \sf \dfrac{0.1p}{1.1p} \ x \ 100[/tex]
[tex]\rightarrow \sf 9.090909091 \% \quad \approx \quad 9.09 \% \quad (rounded \ to \ nearest \ hundredth)[/tex]

m∥n, find the value of x and y.
If m is parallel to n then value of x and y is X = 41° and Y = 41°.
What are Angles?An angle is formed when two straight lines or rays meet at a common endpoint.
Given that line m and n are parallel lines.
Parallel lines are those straight lines that are always the same distance apart from each other.
As y is vertically opposite to the angle 41° . So the value of y is also 41° and angle x is equal to angle y because they are alternate angles. So the value of y is also 41°.
Therefore X = 41° and Y = 41°.

simplified
Answer:
None of the choices are correct
Stefofp-by-step explanation:
Simplify the following:
(-6 x^3 y^4 + 9 x^8 y^2)/(3 x y)
Factor 3 x^3 y^2 out of -6 x^3 y^4 + 9 x^8 y^2:
(3 x^3 y^2 (-2 y^2 + 3 x^5))/(3 x y)
(3 x^3 y^2 (-2 y^2 + 3 x^5))/(3 x y) = 3/3×(x^3 y^2 (-2 y^2 + 3 x^5))/(x y) = (x^3 y^2 (-2 y^2 + 3 x^5))/(x y):
(x^3 y^2 (-2 y^2 + 3 x^5))/(x y)
Combine powers. (x^3 y^2 (-2 y^2 + 3 x^5))/(x y) = x^(3 - 1) y^(2 - 1) (-2 y^2 + 3 x^5):
x^(3 - 1) y^(2 - 1) (-2 y^2 + 3 x^5)
3 - 1 = 2:
x^2 y^(2 - 1) (-2 y^2 + 3 x^5)
2 - 1 = 1:

check your answer by adding the three integers:
41+42+43=126
Answer:
40, 42 and 44Step-by-step explanation:
An Integer is even, if it's divisible by two. it's also a multiple of two.let first integer= Y note : Y is an even number.
second integer= (Y+2)
third integer = (Y+4)
from the question,
Y+Y+2+Y+4= 126
3Y+6 = 126
3Y = 126-6
3Y = 120
dividingbothsides by (3)
3Y/3 = 120/3
Y= 40
therefore, the even integers are:
40
(Y+2)= 40+2= 42
(Y+4) =40+4= 44
check!!!adding the three numbers40+42+44= 126when you multiply a negative by a positive what is the outcome?
it would be negative because negetive overcomes positive.
Answer:
The outcome is a negative because when doing multiplication of negative times positive your answer will always be a negative. For an example, -4*9= -36 so it would be negative.
