Determinar que Recipiente tiene mayor densidad; el recipiente A pesa 1.2 toneladas y tiene un volumen de 120 m³ mientras que el recipiente B pesa 2.4 toneladas y tiene un volumen de 240 m³. ¿Cuál recipiente tiene mayor densidad?
Answer:
Ambos recipientes tienen la misma densidad, es decir, 10 kilogramos por metros cúbicos.
Step-by-step explanation:
Recordamos que la densidad de un material uniforme ([tex]\rho[/tex]), medido en kilogramos por metro cúbico, está definido por:
[tex]\rho = \frac{m}{V}[/tex] (1)
Donde:
[tex]m[/tex] - Masa, medido en kilogramos.
[tex]V[/tex] - Volumen, medido en metros cúbicos.
Ahora calculamos la densidad de cada recipiente:
Recipiente A ([tex]m =1200\,kg[/tex], [tex]V = 120\,m^{3}[/tex])
[tex]\rho = \frac{1200\,kg}{120\,m^{3}}[/tex]
[tex]\rho = 10\,\frac{kg}{m^{3}}[/tex]
El recipiente A tiene una densidad de 10 kilogramos por metro cúbico.
Recipiente B ([tex]m = 2400\,kg[/tex], [tex]V = 240\,m^{3}[/tex])
[tex]\rho = \frac{2400\,kg}{240\,m^{3}}[/tex]
[tex]\rho = 10\,\frac{kg}{m^{3}}[/tex]
El recipiente B tiene una densidad de 10 kilogramos por metro cúbico.
Ambos recipientes tienen la misma densidad, es decir, 10 kilogramos por metros cúbicos.
At Escobar Middle School, 5% of sixth-grade students, which is 20 students, are enrolled in both art and choir. How many sixth-grade students are there in total
The total number of sixth-grade students at Escobar Middle School is 400 students
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
Let the total number of students in sixth grade = x
5 % of sixth grade students is = 20 students
So ,
We need to calculate the total 100 % students in the sixth-grade
And ,
10 % of sixth-grade students = 2 x 5 % of sixth grade students
= 2 x 20 students
= 40 students
Now ,
100 % of sixth-grade students x = 10 x 10 % of sixth-grade students
= 10 x 40 students
= 400 students
Therefore , there are 400 students
Hence , the total number of sixth-grade students is 400 students

X varies directly as the cube root of y .x=6when y=8.Find the value of x when y=64.
Answer:
The value of x is 12.
Step-by-step explanation:
Given that x is directly proportional to y so the expression will be x = k (³√y) where k is the constant. First, you have to find the value of k :
[tex]x = k \: (\sqrt[3]{y} )[/tex]
[tex]let \: x = 6,y = 8[/tex]
[tex]6 = k \: (\sqrt[3]{8} )[/tex]
[tex]6 = k(2)[/tex]
[tex]k = 3[/tex]
Next, you have to find the value of x, by substituting y = 64 into the expression :
[tex]x = 3 \: ( \sqrt[3]{y} )[/tex]
[tex]x = 3( \sqrt[3]{64} )[/tex]
[tex]x = 3(4)[/tex]
[tex]x = 12[/tex]

slope is 2
y intercept is 3
Write an equation for the following data plz :)
Answer:
y = 4x + 1
Y values increase by 4, X values increase by 1.
M or slope, = 4/1 or 4
Y-intercept is when x = 0
When x = 0 in this case, y = 1.
So,
y = 4x +1
Answer:
y = 4x + 1
Step-by-step explanation:
This is the y = mx + b format, hopefully its useful for you! It's a linear equation because all the values grow at a constant rate.
The y-intercept is 1 and it's rise over run which means that you start at 1 on your y-intercept when graphing and then rise 4 and run 1 to the right because it's a positive slope.

An isosceles triangle has base angles that each measure 42 degrees.Which equation can be used to find z, the measure of the third angle of this isosceles triangle in degrees
Answer:
z+42+42=180
Step-by-step explanation:
Since it is an isosceles triangle, the two base angles are the same and remember all the angles add to 180. So use this equation:
z+42+42=180
If you need to find z, it is 96.
Check: 96+42+42=180
3(7 - 2x) - 19 - 5(4- x) = 3(8 - 6x) - 9x + 5(4- x)
Answer:
x=2
Step-by-step explanation:
3(7-2x)-19-5(4-x) = 3(8-6x)-9x+5(4-x)
or, 21-6x-19-20+5x = 24-18x-9x+20-5x
or, 21-19-20-6x+5x = 24+20-18x-9x-5x
or, -18-x = 44-32x
or, -x+32x = 44+18
or, 31x = 62
or, x = 62/31
or, x = 2
Answer:
Step-by-step explanation:
21-6x-19-20+5x=24-18x-9x+20-5x distribution property
-x-18=44-32x common factors
31x-18=44 add 32x to both sides
31x=62 add 18 to both sides
x=2 divide 31 to both sides(equals 2) so x equals 2

Given log3 4 = 1.262 and log3 7 = 1.771, what is the value of log3 (7/16)?
Answer:
[tex]log_3(\frac{7}{16}) =-0.753[/tex]
Step-by-step explanation:
Use the laws of log()
[tex]log_x(\frac{a}{b}) =log_x(a)-log_x(b)[/tex]
[tex]log_3(\frac{7}{16}) =log_3(7)-log_3(16)[/tex]
[tex]log_3(\frac{7}{16}) =log_3(7)-log_3(4^2)[/tex] you can move exponent outside of log()
[tex]log_3(\frac{7}{16}) =log_3(7)-2log_3(4)[/tex]
[tex]log_3(\frac{7}{16}) =(1.771)-2(1.262)[/tex]
[tex]log_3(\frac{7}{16}) =-0.753[/tex]
The required value of log₃ (7/16) is 0.753 which is determined by properties of logarithms.
What are the properties of logarithms?There are four basic properties of logarithms:
logₐ(xy) = logₐx + logₐy.
logₐ(x/y) = logₐx - logₐy.
logₐ(xⁿ) = n logₐx.
logₐx = logₓa / logₓb.
The functions of logarithmic are given in the question
log₃ 4 = 1.262 and log₃ 7 = 1.771
We have to determine the value of log₃ (7/16)
⇒ log₃ (7/16) = log₃ 7 - log₃ 16
⇒ log₃ (7/16) = log₃ 7 - log₃ 4²
Using property of logarithm logₐ(xⁿ) = n logₐx.
⇒ log₃ (7/16) = log₃ 7 - 2 log₃ 4
Substitute the values of log₃ 4 = 1.262 and log₃ 7 = 1.771 in the above equation,
⇒ log₃ (7/16) = 1.771 - 2(1.262)
⇒ log₃ (7/16) = 1.771 - 2.524
⇒ log₃ (7/16) = 0.753
Therefore, the required value of log₃ (7/16) is 0.753.
