En una construccion hay 376 ladrillos en tres grupos. El segundo tiene 24 ladrillos mas que el primero el tercero dos veces mas que el segundo cuantos ladrillos hay en cada grupo porfa con proceso
Answers
Resolviendo un sistema de ecuaciones veremos que en el grupo más pequeño hay 76 ladrillos, en el del medio hay 100, y en el mas grande 200.
¿Cuantos ladrillos hay en cada grupo?
Definamos las variables:
x = número de ladrillos en el primer grupo:y = número de ladrillos en el segundo grupo:z = número de ladrillos en el tercer grupo:Sabemos que el total es 376
x + y + z = 376
Y con la información dada, podemos escribir:
y = 24 + x
z = 2y
Entonces tenemos un sistema de ecuaciones:
x + y + z = 376
y = 24 + x
z = 2y
Para resolver estpo, primero podemos reemplazar la tercer ecuacion en la primera:
x + y + 2y = 376
Y ahora reemplazar la segunda ecuacion ahi.
x + (24 + x) + 2*(24 + x) = 376
Ahora podemos resolver esto para x.
4x + 3*24 = 376
4*x = 376 - 3*24 = 304
x = 304/4 = 76
Ahora que conocemos el valor de x:
y = 24 + x = 24 + 76 = 100
z = 2*y = 2*100 = 200
Entonces, en el grupo más pequeño hay 76 ladrillos, en el del medio hay 100, y en el mas grande 200.

Enter the number that belongs in the green box. 4 51° 109°
Answers
The answer choice which belongs in the green box and is the longest side of the triangle as required is; 11.06.
What is the length of the longest side?It follows from the task content that since the sum of angles in a triangle is; 180°, the missing angle measure is; 180 - 51 - 109° = 20°.
Consequently, it follows from the sine law that;
4 / sin 20° = x / sin 109°
x = 4 sin 109° / sin 20°
x = 11.06.
Ultimately, the number that belongs in the green box is; 11.06.

Let A be a 7×5 matrix with rank equal to 4 and let b be a vector in R8. The four fundamental sub- spaces associated with A are R(A), N(AT ), R(AT ), and N (A).
Answers
The value of R(A) = 4, N(AT ) = 3, R(AT ) = 4, and N (A) = 3.
Given that
Dimension of matrix = 7×5
Rank of matrix = 4
The range space of A,
Which is a subspace of R, is known as R(A).
It is made up of all conceivable linear combinations of A's columns.
The dimension of R(A) = rank of A,
Which is 4 in this case.
The null space of the transpose of A,
Which is also a subspace of R, is designated as N(AT).
All potential answers to the equation ATx = 0,
Where x is a R column vector, are included in it.
N(AT) has a dimension = nullity of A,
which in this case is 3 in this example.
The range space of the transposition of A, is designated as R(AT).
The rows of A are arranged in all conceivable linear configurations.
The rank of A = 4
Thus it equal to dimension of R(AT).
N(A) is the null space of A.
Axe = 0, where x is a column vector in R, are included in it.
The nullity of AT, which is three, is likewise equivalent to the dimension of N(A).

(4a+6)-(3a²-9a+1)=-3a²+ 13a +5
(12c-8c²)+(5c²- 10c) = -3c²+2c
Answers
The first equation is incorrect.
The second equation is correct.
The third equation is correct.
Let's go through each equation and determine whether it is correct or incorrect:
(b²+7b-9)+(4b-6b²) = -8b² + 14b-9
To determine if this equation is correct, we need to simplify both sides and check if they are equal.
On the left side:
(b²+7b-9)+(4b-6b²) = b² - 6b² + 7b + 4b - 9 = -5b² + 11b - 9
On the right side:
-8b² + 14b - 9
Comparing both sides, we can see that -5b² + 11b - 9 is not equal to -8b² + 14b - 9. Therefore, the equation is incorrect.
(4a+6)-(3a²-9a+1)=-3a²+ 13a +5
Again, we need to simplify both sides of the equation and check if they are equal.
On the left side:
(4a+6)-(3a²-9a+1) = 4a + 6 - 3a² + 9a - 1 = -3a² + 13a + 5
On the right side:
-3a² + 13a + 5
Comparing both sides, we can see that -3a² + 13a + 5 is equal to -3a² + 13a + 5. Therefore, the equation is correct.
(12c-8c²)+(5c²- 10c) = -3c²+2c
Again, let's simplify both sides and compare them.
On the left side:
(12c-8c²)+(5c²- 10c) = 12c - 8c² + 5c² - 10c = -3c² + 2c
On the right side:
-3c² + 2c
Comparing both sides, we can see that -3c² + 2c is equal to -3c² + 2c. Therefore, the equation is correct.

How would you solve
"if f(x) / (x - 2) = x ^ 3 + 2x - 4 + 13/(x - 2) what is f(2)"
and
"if f(x) / (x + 3) = 3x ^ 2 - 4x + 2 what is f(-3)"
Answers
The denominator is zero (0/0 is undefined), we cannot determine the exact value of f(-3) using this equation.
To solve the given equations, we need to find the value of the function f(x) for specific values of x.
"If f(x) / (x - 2) = x³ + 2x - 4 + 13/(x - 2), what is f(2)?"
To find f(2), we can substitute x = 2 into the equation and solve for f(2).
Plugging in x = 2, we get:
f(2) / (2 - 2) = 2³ + 2(2) - 4 + 13/(2 - 2)
Since the denominator is zero (2 - 2 = 0), the equation is undefined. Therefore, there is no solution for f(2) in this case.
"If f(x) / (x + 3) = 3x² - 4x + 2, what is f(-3)?"
To find f(-3), we can substitute x = -3 into the equation and solve for f(-3).
Plugging in x = -3, we get:
f(-3) / (-3 + 3) = 3(-3)² - 4(-3) + 2
Simplifying, we have:
f(-3) / 0 = 3(9) + 12 + 2
f(-3) / 0 = 27 + 12 + 2
f(-3) / 0 = 41
Additional information or context is needed to solve for f(-3).

sam rented a truck for one day there was a base fee of 18.99 and there was an additional fee of 79 cents for each mile driven. Sam had to pay 213.33 when he returned the truck how many miles did he drive the truck.
Answers
Sam drove approximately 246 miles.
Let's start by subtracting the base fee from the total amount Sam paid to find the additional fee he incurred for the miles driven:
213.33 - 18.99 = 194.34
We know that the additional fee is 79 cents per mile, so we can set up an equation to find the number of miles Sam drove:
194.34 = 0.79x
where x is the number of miles driven.
To solve for x, we can divide both sides of the equation by 0.79:
x = 194.34 / 0.79 ≈ 246
Therefore, Sam drove approximately 246 miles.

If $5.00 were invested at 3% interest 600 years ago, how much would that investment be worth today?
Answers
A = P * (1 + r/n)^(n*t)
Where:
A = the future value of the investment
P = the principal amount (initial investment)
r = annual interest rate (as a decimal)
n = number of times interest is compounded per year
t = number of years
In this case, the principal amount (P) is $5.00, the annual interest rate (r) is 3% (or 0.03 as a decimal), the investment has been held for 600 years (t), and the interest is compounded annually (n = 1).
Plugging these values into the formula, we get:
A = 5 * (1 + 0.03/1)^(1*600)
Calculating this expression:
A = 5 * (1.03)^600
A ≈ 5 * 37.282
A ≈ 186.41
Therefore, the $5.00 investment would be worth approximately $186.41 today after 600 years at a 3% interest rate.
