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
Two angles in a triangle are equal and their sum is equal to the third angle in the triangle. What are the measures of each of the three interior angles?
Answer:
45º, 45º, 90º
Step-by-step explanation:
Assume angles are x then third is x+x = 2x.
sum of angles in a triangle = 180
=> x + x + 2x = 180
=> 4x = 180
=> x = 180/4 = 45
so, angles are 45,45 and 90.

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
the number of baby elephants is 2
There are 40 students in a class. The teacher gave each female student 5
counters and each male student 3 counters. After the distribution of the
counters, the teacher realized that the female students had 128 more counters
than the male students,
Thus the required number of male and female students are 9 and 31 respectively.
Mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
here,
Let the number of male students is x and the number of female students be y,
According to the question,
x + y = 40
x = 40 - y ----- (1)
Now,
again from the question,
5y = 3x + 128
3x = 5y - 128
from equation 1
3 (40 - y) = 5y -128
120 - 3y = 5y - 128
120 + 128 = 8y
8y = 248
y = 31
Now,
From equation 1
x = 40 - y
x = 40 - 31
x = 9
Thus the required number of male and female students are 9 and 31 respectively.

need help asap please
Answer:
this is way to hard
Step-by-step explanation:
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.
A $55 pair of shoes was discounted 15 percent, making the sale price $46.75. The discounted price was then discounted again by 10 percent. Explain how you would find the final price of the shoes.
Answer:
Hi there
Your answer is
$42.08
To find the final price of the shoes, we would use the 15% discounted price, $46.75, as 100% and find 10% discount of that.
46.75 = 100%
/10
4.675 = 10%
Now, subtract 10% from the 15% discounted price
46.75 - 4.675 = 42.075$ Round up
$42.08
Answer:
find the final price by subtracting 10% from the sale price of $46.75 which is $4.68 making the final price $42.07
