solution of 20mn/60m
Answer:
1/3000 or 0.000333....
Step-by-step explanation:
I think you mean 20mm / 60 m
1 mm = 0.001m
So the division becomes:
(0.001* 20) / 60
= 0.02 / 60
= 0.00033.....
or as a fraction it is
2/6000
= 1/3000.

Given ∠A and ∠B are vertical angles with m∠A=20x+10 and m∠B=30x−10 .
What is x?
Enter your answer in the box
PLEASE HELP I APPRECIATE IT
Answer:
x = 2
Step-by-step explanation:
Vertical angles are equal to each other. It means that,
∠A = ∠B
So,
20x+10 = 30x−10
Taking like terms together, we get :
20x-30x=-10-10
-10x=-20
x=2
So, the value of x is 2.

Answer:
a
[tex]P(X < 65) = 0.003467[/tex]
b
[tex]P(86 < X < 110 )= 0.63928 [/tex]
c
[tex]P(X > 120 ) =0.062024[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = \$ 100[/tex]
The standard deviation is [tex]\sigma = \$ 13[/tex]
Generally the probability that the monthly utility bills is less than $65 is mathematically represented as
[tex]P(X < 65) = P(\frac{X - \mu }{\sigma } < \frac{65 - 100 }{13 } )[/tex]
Generally
[tex]\frac{X - \mu }{\sigma } = Z (The\ standardized \ value \ of\ X )[/tex]
So
[tex]P(X < 65) = P(Z < -2.70 )[/tex]
From the z-table
[tex]P(Z < -2.70 ) = 0.003467[/tex]
So
[tex]P(X < 65) = 0.003467[/tex]
Generally the probability that a randomly selected utility bill is between $86 and $110 is mathematically represented as
[tex]P(86 < X< 110 )= P( \frac{86 -100}{ 13} < \frac{X - \mu}{\sigma } < \frac{86 -100}{ 13} )[/tex]
=> [tex]P(86 < X < 110 )= P( \frac{86 -100}{ 13} < Z < \frac{110 -100}{ 13} )[/tex]
=> [tex]P(86 < X < 110 )= P(-1.08 < Z < 0.77 )[/tex]
=> [tex]P(86 < X < 110 )= P(Z < 0.77 ) - P(Z < -1.08 ) [/tex]
From the z-table
[tex]P(Z < 0.77 ) = 0.77935[/tex]
and
[tex]P(Z < -1.08 ) = 0.14007[/tex]
So
[tex]P(86 < X < 110 )= 0.77935 - 0.14007 [/tex]
=> [tex]P(86 < X < 110 )= 0.63928 [/tex]
Generally the probability that the monthly utility bills is more than $120 is mathematically represented as
[tex]P(X >120 ) = P(\frac{X - \mu }{\sigma } > \frac{120 - 100 }{13 })[/tex]
=> [tex]P(X > 120 ) = P(Z > 1.538 )[/tex]
From the z-table
[tex]P(Z > 1.54 ) = 0.062024[/tex]
So
[tex]P(X > 120 ) =0.062024[/tex]

si un submarino esta a - 83 metros a nivel del mar, sube a -15 cuantos metros subio?
Answer:
El submarino subió 68 metros
Step-by-step explanation:
Desplazamiento
Si un cuerpo cambia de posición desde X1 hasta X2, su cambio de posición se calcula como:
X=X2-X1
En el caso de nuestro submarino, su posición original era a X1=-83 m, luego sube a la posición X2=-15 m, así que su cambio de posición o desplazamiento es:
X=-15-(-83)=-15+83=68 m
El submarino subió 68 metros

The area of a square is given by A= s2 where s is the length of each side of the square if the area of a square room is 64 square meters what is the length of 1 side of the room in meters
9514 1404 393
Answer:
8 m
Step-by-step explanation:
Using the given information, we know that ...
64 m^2 = A = s^2
(8 m)^2 = s^2
8 m = s
The length of one side of the room is 8 meters.
A. Write the first four terms of the sequence, given the nth term formula

C. Find the general rule or nth term for each sequence
1. 7, 12, 17, 22,...
2. 2, 6, 12, 20,...
D. Determine whether each sequence is arithmetic or not. Find the common difference for each arithmetic sequence
1. 4, 8, 12, 16,..
2. 13, 10, 7, 4,...
3. -10, -8, -6, -4,..
4. 1, 6, 8, 11, 12,..
5. 5,6,12,13
Step-by-step explanation:
A.let n be 1
a1=2(1)+3
T1=5
let n be 2
2(2)+3
T2=7
T3=2(3)+3
=9
T4=2(4)+3
=11
A. For the sequence given by the nth term formula an = 2n + 3, the first four terms are:
a1 = 2(1) + 3 = 5
a2 = 2(2) + 3 = 7
a3 = 2(3) + 3 = 9
a4 = 2(4) + 3 = 11
For the sequence given by the nth term formula an = n² - 1, the first four terms are:
a1 = 1² - 1 = 0
a2 = 2² - 1 = 3
a3 = 3² - 1 = 8
a4 = 4² - 1 = 15
B. The missing terms for the sequence 57, 47, 37, 27, 17 are:
57, 47, 37, 27, 17
The missing terms for the sequence -12,-6, , 0, 12, 24, 36 are:
-12, -6, 0, 12, 24, 36
The missing terms for the sequence -4, 8,20, , 16, -20 are:
-4, 8, 20, 16, -20
C. The general rule or nth term for the sequence 7, 12, 17, 22,... is:
an = 5n + 2
The general rule or nth term for the sequence 2, 6, 12, 20,... is:
an = n² + 1
D. The sequence 4, 8, 12, 16,.. is an arithmetic sequence with a common difference of 4.
The sequence 13, 10, 7, 4,... is an arithmetic sequence with a common difference of -3.
The sequence -10, -8, -6, -4,.. is an arithmetic sequence with a common difference of 2.
The sequence 1, 6, 8, 11, 12,.. is not an arithmetic sequence as there is no common difference between consecutive terms.
The sequence 5, 6, 12, 13,... is not an arithmetic sequence as there is no common difference between consecutive terms.

Select the correct answer. What is the factored form of m6 − 64n3? A. (m2 + 4n)(m4 − 4m2n + 16n2) B. (m − 4n2)(m2 + 4mn2 + 16n4) C. (m + 4n2)(m2 − 4mn2 + 16n4) D. (m2 − 4n)(m4 + 4m2n + 16n2)
Answer:
D.
Step-by-step explanation:
(m^2- 4n)(m^4+4m^2n+16n^2)
Option D is our correct answer.
i.e (m² - 4n) ([tex]m^{4}[/tex] + 4nm + 16n²).
Given,
[tex]m^{6}[/tex] - 64n³
We need to find the factored form of this.
And select the correct options.
A. (m2 + 4n)(m4 − 4m2n + 16n2)
B. (m − 4n2)(m2 + 4mn2 + 16n4)
C. (m + 4n2)(m2 − 4mn2 + 16n4)
D. (m2 − 4n)(m4 + 4m2n + 16n2)
What is the formula of (a³ - b³)?It is given as:
( a - b ) ( a² + ab + b² )
Find the factored form [tex]m^{6}[/tex] - 64n³
We can write this as,
[tex](m^{2})^3[/tex] - 4³n³
(m²)³ - (4n)³
This is in the form of (a³ - b³).
Applying this formula.
Now,
(m² - 4n) ((m²)² + 4nm + (4n)²)
(m² - 4n) ([tex]m^{4}[/tex] + 4nm + 16n²)
Thus Option D is our correct answer.
i.e (m² - 4n) ([tex]m^{4}[/tex] + 4nm + 16n²).

How many baby elephants were weighed?
Please help as soon as possible.
Answer:
just remember that each baby elephant weight 3/8 of a ton
and all together weight 3/4 of a ton
so how many baby elephants will be ,let be x a unknown number of them
so
x*(3/8) =3/4
because multiplying the number of baby elephants with their body weight gives the total weight of all baby elephants.
so
x=(3/4)*(8/4)=2
