Answer:
Hulain is 10 and Thomas is 5
Step-by-step explanation:
soooo
add variables
thomas age: t
hulians age: h
h = 2t
15 = t + 2t
umm i dont remember if you can add t and 2t they have the same um variable and power ig. if you can then:
15 = 3t
t = 5
sooo now hulians turn!
h = 2t
h = 2(5)
h = 10

An angle measures 64.8° less than the measure of its complementary angle. What is the measure of each angle?
Answer:
77.4 degrees and 12.6 degrees
Step-by-step explanation:
Let the angles be x and x - 64.8.
Therefore, on the basis of knowledge that complementary angles add up to 90 degrees :
x + x - 64.8 = 90
2x = 154.8
x = 77.4 degrees
x - 64.8 = 77.4 - 64.8 = 12.6 degrees

Find the slope of the line passing through the two points (-2,1) (6,-1)
Answer:
-1/4
Step-by-step explanation:
We use the formula:
[tex] \frac{y₂ -y₁}{x₂ -x₁} [/tex]
plugging in we have
[tex]\frac{ (- 1)-(1)}{(6) -( - 2)} = \frac{ - 2}{8} = - \frac{1}{4} [/tex]
Therefore our slope is -1/4

sobre un estante se pueden colocar 30 libros de ciencias y 6 lubros de letras o 18 libros de letras y 10 libros de ciencias ¿cuantos libros de letras unicamente se pueden colocar?
Usando un sistema de ecuaciones vamos a ver que entran 24 libros de letras en el estante.
Cuantos libros de letras se pueden colocar?
Vamos a usar las variables:
x = peso de un libro de ciencias.y = peso de un libro de letras.Por el texto, podemos saber que el peso maximo que tolera el estante esta dado por el sistema de ecuaciones.
30*x + 6*y = P
10*x + 18*y = P
Podemos igualar esas dos ecuaciones para obtener:
30x + 6y = 10x + 18y
30x - 10x = 18y - 6y
20x = 12y
x = (12/20)*y
Ahora, podemos reemplazar esto en una de las dos ecuaciones, por ejemplo la primera:
30x + 6y = P
30*(12/20)y + 6y = P
(3/2)*12*y + 6y = P
18y + 6y = P
24y = P
Así concluimos que entran 24 libros de letras en el estante.

Step-by-step explanation:
The function c(x) = 400x – 0.2x2 represents the total costs for a company to produce a product, where c is the total cost in dollars and x is the number of units sold. which statement is true? one thousand units have the minimum cost of $200,000. one thousand units have the maximum cost of $200,000. two thousand units have the minimum cost of $800,000. two thousand units have the maximum cost of $800,000.
At x = 1000 we get the c(1000) = 2000,000. Second statement 'one thousand units have the maximum cost of $200,000' is true.
It is given that the function [tex]\rm c(x)=400x-0.2x^2[/tex] represents the total costs for a company to produce a product, where c is the total cost in dollars and x is the number of units sold.
It is required to find which statement is true, mentioned in the question.
What are the maxima and minima of a function?Maxima and minima of a function are the extrema within the range, in other words, the maximum value of a function at a certain point is called maxima and the minimum value of a function at a certain point is called minima.
We have a function:
[tex]\rm c(x)=400x-0.2x^2[/tex]
To find the maxima and minima of any function we differentiate the function with respect to [tex]\rm x[/tex] and equate to zero.
[tex]\rm \frac{d \ c(x)}{dx} =\frac{d}{dx} (400x-0.2x^2)[/tex]
[tex]\rm \frac{d \ c(x)}{dx} =\frac{d}{dx} (400x)-\frac{d}{dx} (0.2x^2)\\\rm \frac{d \ c(x)}{dx} =400-(0.2\times2x)\\\rm \frac{d \ c(x)}{dx} =400-0.4x[/tex]
For maxima and minima [tex]\rm \frac{d \ c(x)}{dx} =0[/tex]
[tex]\rm 400-0.4x=0\\\rm x=\frac{400}{0.4} \\\rm x=1000[/tex]
If we find the seconnd differentiate, we get
c''(x) = -0.4 < 0
It means at x = 1000 we will get the maximum value of a function.
[tex]\\\\\rm c(1000) = 400(1000) - 0.2(1000)^2\\\rm c(1000)= 200,000[/tex]
Thus, at x = 1000 we get the c(1000) = 2000,000. Second statement is true.

https://brainly.com/question/6422517
Answer:
B
Step-by-step explanation:
To determine the maxima and minima of the polynomial, differentiate the given based on x and equate to 0. C(x) = 400x - 0.2x² dC(x) / dt = 400 - 0.4 x = 0 The value of x is 1000. This is the value of the maxima. As the value of C(x) continously becomes lesser as the value of x is set higher, the minima is not identified. Substitute x to the original equation, C(x) = (400)(1000) - 0.2(1000²) = $ 200,000Thus, the answer is letter B.

Step-by-step explanation:
You can rewrite the denominator as:
-2(2x-6) so the equation becomes:

from which you can see that not only should x ≠ 3, but for all values of x≠3 the equation is false.

Answer:
First, we have to find the LCM of 12 and 8 which would be 24. Since we have to multiply 8 by 3, and 12 by 2, then the shortest height would be two 12-inch boxes, and three 8-inch boxes.
