Answer:
64 : 216
Step-by-step explanation:
Given the ratio of the heights = a : b, then
ratio of volumes = a³ : b³
Here the ratio of heights = 4 : 6 = 2 : 3 ← in simplest form, thus
ratio of volumes = 4³ : 6³ = 64 : 216 = 8 : 27 ← in simplest form

What is the value of s and what is the correct amount of units
Step-by-step explanation:
Here,
ABCD is rhombus,
AB=9s+29
CD =10s -18
now, AB=CD (opposite side of rhombus is parallel and equal)
or,9s +29=10s-18
or, 10s -9s= 29+18.
The value of s is 47.
Therefore, the measure of AB is 9×47+29.
=452.

Which is the solution to this equation (X-2)(x+5)=18
Answer:
x=-7 x=4
Step-by-step explanation:
(X-2)(x+5)=18
FOIL
x^2 +5x -2x-10 =18
Combine like terms
x^2 +3x -10 = 18
Subtract 18 from each side
x^2 +3x -10 -18 = 0
Combine like terms
x^2 +3x -28 =0
Factor
What two numbers multiply to -28 and add to 3
7*-4 = -28
7+-4 = 3
( x+7) ( x-4) =0
Using the zero product property

Manuel y Rosa, desean hacer un regalo a sus tíos por Fiestas patrias, para lo cual visitaron distintos centros comerciales donde venden artículos o herramientas de carpintería. En uno de ellos, observaron que una caja de herramientas les costaba 180 soles. Al no contar con ese monto, decidieron volver la primera semana de Julio, después de juntar sus ahorros. Pero se dieron cuenta que el precio se había incrementado en un 10% . Al faltarles dinero, decidieron volver la siguiente semana, en la que observan que el precio de la caja de herramientas se había incrementado en un 20% del precio que observaron en la primera semana de Julio. Ellos cuentan con 250 soles. Manuel dice: "el precio se ha incrementado en 35% del precio del precio inicial pero nos alcanza y nos sobra 7 soles" A lo que Rosa dice: " no se ha incrementado en un 35% pero sí nos sobrarían 5 soles?
Answer:
El incremento total con respecto al precio inicial es de 32% y Rosa tiene razón con respecto al porcentaje (no se incrementó 35%).
En cuanto al dinero que les sobra, ninguno de ellos está en lo correcto pues les sobran 12 soles.
Step-by-step explanation:
En un principio, la caja de herramientas costaba 180 soles.
Después de una semana el precio se incrementó 10%, el 10% de 180 soles es 18 por lo que la caja costaba 180 + 18 = 198 soles.
Ellos volvieron la siguiente semana y vieron que el precio se había incrementado un 20% con respecto a la semana anterior, el 20% de 198 es igual a 198 x 0.20 = 39.6 por lo que el precio ahora era de 198 + 39.6 = 237.6 soles.
Para saber el incremento total con respecto al precio inicial podemos hacer una proporción:
180 soles : 100
237.6 soles : x
Despejando x tenemos que:
[tex]x= \frac{237.6(100)}{180}=\frac{23760}{180}=132[/tex]
Por lo tanto, el incremento total con respecto al precio inicial es de 32% y Rosa tiene razón con respecto al porcentaje (no se incrementó 35%)
Sin embargo, ellos cuentan con 250 soles y la caja cuesta 237.6 ≈238 soles, por lo tanto, les alcanza y les sobran 250 - 238 = 12 soles.
Which best describes the relationship between the lines with equations 5x +y = 4 and 20.0 + 4y = 16?
Answer:
There is no relationship, except they do intersect at the point (1, -1). Hope this helps :)

Both given lines are going to intersect at ( 1,-1 ) that's it.
What is a line segment?A line section that can connect two places is referred to as a segment.
The line is here! It extends endlessly in both directions and has no beginning or conclusion.
In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.
Given that
Line 1 ; 5x +y = 4
Line 2 ; 20 + 4y = 16 ⇒ y = -1
At y = -1 the first line is
5x - 1 = 4 ⇒ x = 1
So,
It is clear that line 1 has a point ( 1 .-1 ) and line 2 also passes
through it hence there will an intersection.

find the value of the variable and GH if H is between G and I. GI=5b+2,HI=4b-5, HI=3
Answer:
GH = 9 units
Step-by-step explanation:
Given HI = 4b - 5 and HI 3, then
4b - 5 = 3 ( add 5 to both sides )
4b = 8 ( divide both sides by 4 )
b = 2
Thus
GI = 5b + 2 = 5(2) + 2 = 10 + 2 = 12
GH = GI - HI = 12 - 3 = 9

Answer:
Below
Step-by-step explanation:
To write this function in the standard form simplify it.
● -4(x+2)(x+3)
● -4 (x^2+3x+2x+6)
●-4(x^2+5x+6)
●-4x^2-20x-24
Answer:
y = -4(x+2.5)²+1
Step-by-step explanation:
Standard form is given by f(x) = a(x-h)²+k, where (h,k) is the vertex. We are already given a = -4, and if we graph the equation given, we can see that the vertex is (-2.5, 1). So, we can set up the equation y = -4(x+2.5)²+1.

4. Let’s assume the following statements are true: Historically, 75% of the five-star football recruits in the nation go to universities in the three most competitive athletic conferences. Historically, five-star recruits get full football scholarships 93% of the time, regardless of which conference they go to. If this pattern holds true for this year’s recruiting class, answer the following:
a. Based on these numbers, what is the probability that a randomly selected five-star recruit who chooses one of the best three conferences will be offered a full football scholarship? b. What are the odds a randomly selected five-star recruit will not select a university from one of the three best conferences? Explain. c. Explain whether these are independent or dependent events. Are they Inclusive or exclusive? Explain.
Answer:
a. 0.6975
b. 0.25
c. The events are independent and inclusive
Step-by-step explanation:
a. The proportion of five-star football recruits in the nation that go to universities in the three most competitive athletic conferences = 75%
Therefore, the probability of a five-star football recruits chooses to go to a university in the three most competitive athletic conferences p(A) = 75% or 0.75
The proportion of the times five-star football recruits get full football scholarships = 93%
Therefore, the probability that a five-star football recruit get full football scholarships p(B) = 93% or 0.93
Therefore, the probability that a randomly selected five-star recruit who chooses one of the best three conferences will be offered a full football scholarship can be written as -the probability that a randomly selected five-star recruit who chooses one of the best three conferences and will be offered a full football scholarship is therefore;
p(A) ∩ p(B) = p(A) × p(B) = 0.75×0.93 = 0.6975
b. The probability that a randomly selected five star recruit will not select a university from one of the three best conferences = 1 - p(A) = 1 - 0.75 = 0.25
c. The events are independent as the given probability of occurrence of one event does not alter the probability of the other event
The events are inclusive events are exclusive events as P(A)and P(B) can take place simultaneously.
Describe the function over each part of its domain. State whether it is constant, increasing, or decreasing, and state the slope over each part. (5 points)
Answer:
Pretty simple!
Step-by-step explanation:
First, you need to know about exponential functions. They are like linear functions, but either increase or decrease their rate as they go further along the x-axis.
Linear functions take a simple form: Just a line. Not really much to it!
Their equation is: [tex]y=mx+b[/tex]
Yeah! Now onto Exponential Functions.
Exponential functions are very interesting. This could be that they are hard to solve sometimes, or that I spent over half a year studying them.
Their Graphs usually look like a line that keeps getting lower or higher as they progress.
Essentially, if they keep getting higher and higher(Y-axis wise), this means that they are increasing. Likewise, if they keep getting lower and lower, this means they are decreasing. Pretty simple, right?
Now, to state the slope over each part. To do that, I'm pretty sure you have to find two points that describe that area, use the formula for slope(Below), and I would think you are done.
[tex]m=\frac{y_{1} -y_{2} }{x_{1} -x_{2}}[/tex]

Which of the following is not an identity for tan (X/2)
Answer:
This question is about half-angle trigonometric identities, which are specific formulas that help us to solve problems with half-angles.
In this case, if you need a half-angle identity for the tangent, you could use
[tex]tan(\frac{x}{2} )=\frac{sin(x)}{1+cos(x)}[/tex]
[tex]tan(\frac{x}{2})=\frac{1-cos(x)}{sin(x)}[/tex]
[tex]tan(\frac{x}{2})=\sqrt{\frac{1-cos(x)}{1+cos(x)} }[/tex]
Therefore, the right identity must satisfy the expression above.

At a birthday party, each child is given some chocolates. There are five 5-year-olds, five 6-year-olds and five 7-year-olds at the party. If each child receives three times as many chocolates as their age in years, how many chocolates are given out altogether?
Answer: 270 chocolates
Step-by-step explanation:
Given the following :
Number of 5-year Olds = 5
Number of 6-year Olds = 5
Number of 7-year Olds = 5
Number of chocolates received by each child = 3 times as many chocolate as their age.
Number of chocolates received by 5-year Olds = 3 × 5 = 15 chocolates
Number of chocolates received by 6-year Olds = 3 × 6 = 18 chocolates
Number of chocolates received by 7-year Olds = 3 × 7 = 21 chocolates
Total Number of chocolates received by 5-year Olds = 5 * 15 = 75 chocolates
Total Number of chocolates received by 6-year Olds = 5 * 18 = 90 chocolates
Total Number of chocolates received by 7-year Olds = 5 * 21 = 105 chocolates
Totak number of chocolates altogether :
(75 + 90 + 105) = 270 chocolates
