Answer:
x= -4 and x=6
Step-by-step explanation:
what ever x is that makes (x+4) = 0, so -4
and (x+6)=0, so -6. In other words, solve for x in the factored equations (the equation here is factored) and just solve for zero
what is the geometric mean of 14 and 6
Answer:
8
Step-by-step explanation:
The geometric mean of two numbers 14 and 6 is 2√21.
What are arithmetic and geometric mean?An arithmetic mean can be obtained by taking the sum of all the numbers and dividing it by the number of numbers.
In the case of geometric mean, we multiply the numbers and raise them to the reciprocal of a total number of numbers.
Given, Two numbers 14 and 6.
Now, 14×6 = 84.
Now, we have to take the square root of 84 as we have two numbers.
Therefore, The geometric mean of 14 and 6 is,
= √(84).
= 2√21.

Step-by-step explanation:
A pair of shoes that normally sells for $85.00 goes on sale for 35% off.
Sean thinks that the sale price should be $50.00 but Melanie disagrees and says the price should be $55.25. Aiyanna says they are both wrong and decides the price should be $29.75.
Who is correct and why?
a. Melanie is correct.
b. Sean is correct.
c. Aiyanna is correct.
Answer:
A
Step-by-step explanation:
Melanie is correct
85 x 0.35 = 29.75
85 - 29.75 = 55.25
Answer:
a. Melanie is correct
Step-by-step explanation:
35% of 85= 29.75
*Find this by finding 10% (move decimal place over) and five percent (half of ten percent) and add triple of 10% plus the 5% or look it up*
Subtract this from 85
85-29.75=
$55.25

Answer:
B. (5,5)
C. (3,3)

Step-by-step explanation:
The equation of a circle with radius [tex]r[/tex] and center [tex](h, k)[/tex] is given by:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
From this, we can find that the radius of the circle is [tex]\sqrt{4}=2[/tex] and the center of the circle is at [tex](3, 5)[/tex]. Therefore, the coordinates of all points exactly 2 units away from this center point will lie on the circle.
Out of all options given, the desired answers are:

If a student is selected at random, find the
probability the student is a freshman. Round
to the nearest whole percent.
[?]%
My
The sample space (total number of students) = 30
total number of freshmen = 7
the freshmen = the event considered
.....therefore
probability = 7/30
%probability = 7/30 × 100%
= 23.33% ~ 23%
The solution is, The required probability is 3/4= 75%, is the probability the student is a freshman.
What is the probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.
here, we have,
We have to compute the probability,
P(Female |Junior) because we have to find the probability of the female student and the given condition is that the student is junior.
Determine the total number of juniors.
Juniors=2+6=8
Since the number of females who are junior is 6, determine the required probability.
P(Female|Junior)=6/8
=3/4
=75%
Therefore, the required probability is 3/4 = 75%.

Solve the equation for x.
2/3 (6 – 9x) = 16
A) -2
B) -4
C) -9
D) -12
Answer:
A. - 2
Step-by-step explanation:
Given
2/3 ( 6 - 9x) = 16
or, 6 - 9x = 16 * 3 / 2
or, 6 - 9x = 24
or, - 9x = 24 - 6
- 9x = 18
x = 18 / - 9
Therefore x = - 2

Mezclas de alimentos. Un chef repostero creó una solución de azúcar de 50 onzas constituida por 34% de azúcar con una solución de azúcar al 20% y otra solución al 40%. ¿Qué cantidad utilizó de la solución de azúcar al 20% y de la solución al 40%?
Answer:
Las cantidades empleadas para su preparación son: 15 onzas de solución al 20 % y 35 onzas de solución al 40 %.
Step-by-step explanation:
Podemos estimar la proporción de ingredientes mediante el siguiente promedio ponderado:
[tex]0.34= \frac{0.2\cdot m_{A} + 0.4\cdot m_{B}}{m_{A}+m_{B}}[/tex] (1)
Donde:
[tex]m_{A}[/tex] - Masa de la solución al 20 %, en onzas.
[tex]m_{B}[/tex] - Masa de la solución al 40 %, en onzas.
Podemos simplificar la formula como sigue:
[tex]0.2\cdot x + 0.4\cdot (1-x) = 0.34[/tex] (2)
Donde [tex]x[/tex] es la proporción de la solución al 20 % dentro de la solución final, sin unidades.
Ahora resolvemos para [tex]x[/tex] en (2):
[tex]0.4-0.2\cdot x = 0.34[/tex]
[tex]0.2\cdot x = 0.06[/tex]
[tex]x = \frac{0.06}{0.2}[/tex]
[tex]x = 0.3[/tex]
Este resultado quiere decir que la solución al 34 % es el resultado de 30 % de la solución al 20 % y 70 % de la solución al 40 %. Si conocemos que la solución final tiene una masa de 50 onzas, entonces las cantidades empleadas para su preparación son: 15 onzas de solución al 20 % y 35 onzas de solución al 40 %.

Which equation can be used to find the volume of this solid? 6 in 8 in. 1 7 in. O V. 758 xa ov-+6+8 o v-7x6x8
Answer:
Option 1: V = pi(6)2(8)
Step-by-step explanation:
This is because when we plug in the value given in the picture.
Formula
The way we write this is by using our "r" which is 6. We plug in the 6 for "r" so the equation will look something like this:
Then we will plug in our height "h", which is 8. So the equation will look something like this:
So that's it. Very simple. Just remember to keep the formula in mind and you will get the hang of it.
I hope this help! :D
Equation to calculate volume of solid is V = 6 × 8 × 7
What is equation?An equation is a formula that expresses equality by connecting two expressions with an equal sign =. Equation consists of variables, constants and coefficients. Right side and left side of an equation are in equality.
There are different types of equations as linear equations, quadratic equation etc.
example: 2x + 5y + 7 = 0 is an equation
here, 2, 5 are coefficients of variables x and y, 7 is a constant value
2x² + 5x + 3 = 0 is a quadratic equation.
Given,
measurement of the sides of solid
length = 6in
Width = 8 in
Height = 7 in
Volume = Length×Width×Height
V = 6 × 8 × 7
Volume = 336 in³
Hence, V = 6 × 8 × 7 is the equation to calculate volume of solid.

A bookstore in the mall is trying to determine how many mall shoppers are interested in purchasing
books as gifts. To obtain a random sample, the manager surveys every third person that enters the
bookstore.
Does the sample represent the population? Why or why not?
Select the option that correctly answers both questions.
O yes, because people who are already searching for books will give the best responses
O yes, because every third person that enters the bookstore is representative of all
shoppers in the mall
O no, because the manager needs to survey every person that enters the bookstore in
order to represent the population
O no, because people in the bookstore are interested in purchasing books, so they do
not represent all shoppers in the mall
Answer:
O no, because people in the bookstore are interested in purchasing books, so they do not represent all shoppers in the mall
Step-by-step explanation:
In the bookstore, the best method which the store keeper wanted to adopt is actually not a sample representation of the population. This is because, since it would be a survey of those that interested in purchasing books as gifts, it should be able to factor in other purchasers in the mall rather than those who purchase from the bookstore only.
Doing this, would help to give an accurate representation of both group in the survey.
