10 0breros construyen un complejo 336 días, ¿cuantos días les tomaría hacer el mismo complejo a 15 obreros?
Usando proporciones, se encuentra que 15 obreros hacerían el mismo complejo en 24 días.
Esta pregunta se resuelve por proporciones, usando una regla de tres. Cuanto mayor lo número de obreros, menor el tiempo, o sea, las medidas son inversamente proporcionales, lo que implica que la multiplicación es en línea.10 obreros toman 336 dias. ¿Cual el tiempo necessário para 15 obreros?La regla de três es:
10 obreros - 336 días
15 obreros - x días
Aplicando multiplicación en línea:
[tex]15x = 336(10)[/tex]
[tex]x = \frac{336(10)}{15}[/tex]
[tex]x = 24[/tex]
15 obreros hacerían el mismo complejo en 24 días.

What is the slope-intercept equation of the line containing the points (–5, 22) and (4, 49) ?
Answer:
[tex]y=3x+37[/tex]
Step-by-step explanation:
Determine slope:
[tex]Slope=m=\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}=\frac{49-22}{4-(-5)}=\frac{27}{4+5}=\frac{27}{9}=3[/tex]

what is 5.56 s divided by 6.42 S
Answer:
0.86
step by step explain:
first you want to get a calculator and you want to put in 5.56 divide 6.42
Answer:
= 0.866
Step-by-step explanation:
By moving the decimal point two places to the right, you can convert the divisor 6.42 to a whole number. Then, in the dividend, move the decimal point two places to the right.
Then we have the equation: 556 ÷ 642 = 0.866
and therefore: 5.56 ÷ 6.42 = 0.866
both calculated to three decimal places.

Which function represents the following graph? On a coordinate plane, a cubic function has an inflection point at (negative 3, 3) and crosses the x-axis at (0, 4. 5). Y = StartRoot x minus 3 EndRoot 3 y = StartRoot x 3 EndRoot 3 y = RootIndex 3 StartRoot x minus 3 EndRoot 3 y = RootIndex 3 StartRoot x 3 EndRoot 3.
The function represents the graph is (d) [tex]y = \sqrt[3]{x+3} + 3[/tex]
The points on the graph are given as:
[tex](x,y) = (-3,3)[/tex] --- the inflection point
[tex](x,y) = (0,4.5)[/tex] --- the y-intercept
The function that satisfy the above points is:
[tex]y = \sqrt[3]{x+3} + 3[/tex]
The proof is as follows:
At the inflection point, we have the x value to be -3.
So, the function becomes
[tex]y = \sqrt[3]{x+3} + 3[/tex]
[tex]y = \sqrt[3]{-3+3} + 3[/tex]
[tex]y = \sqrt[3]{0} + 3[/tex]
[tex]y = 0+ 3[/tex]
[tex]y = 3[/tex] ---- the y-value at the inflection point is true for x = -3
Also, at the y-intercept, we have the x-value to be 0
So, the function becomes
[tex]y = \sqrt[3]{x+3} + 3[/tex]
[tex]y = \sqrt[3]{0+3} + 3[/tex]
[tex]y = \sqrt[3]{3} + 3[/tex]
[tex]y = 1.45+ 3[/tex]
[tex]y = 4.45[/tex] ---- the y-value at the y-intercept is true for x = 0
Hence, the function represents the graph is (d) [tex]y = \sqrt[3]{x+3} + 3[/tex]

Why is it helpful to use the rational zero theorem in finding the zeros of polynomial function? Explain your answer.
Answer:
The rational roots theorem is a very useful theorem. It tells you that given a polynomial function with integer or whole number coefficients, a list of possible solutions can be found by listing the factors of the constant, or last term, over the factors of the coefficient of the leading term.
Hope that helps.
Answer:
Finding the Zeros of Polynomial Functions The Rational Zero Theorem helps us to narrow down the list of possible rational zeros for a polynomial function. Once we have done this, we can use synthetic division repeatedly to determine all of the zeros of a polynomial function. Given a polynomial functionuse synthetic division to find its zeros.

Solve: 3x²+9x+6 = 0
Thank you.
Given quadrant equation:
3x² + 9x + 6 = 0
Here we see that,
→ Product of coefficient of x² and constant term = 3 × 6 = 18
→ Sum of coefficient of x² ans constant term = 3 + 6 = 9
So the given equation can be written as,
⇛3x² + 6x + 3x + 6 = 0
On taking the common terms, we get
⇛3x(x + 2) + 3(x + 2) = 0
On grouping the common terms, we get
⇛(3x + 3)(x + 2) = 0
Here either (3x + 3) = 0 or (x + 2) = 0. So,
⇛3x + 3 = 0 or x + 2 = 0
⇛3x = -3 or x = -2
⇛x = -3/3 or x = -2
⇛x = -1 or x = -2

1. 5/3 is not equal to 3/5.
2. 7-(4+3) is equal to (4+3)-7
3. (x + y) + 1 is equal to x + (y + 1)
Step-by-step explanation:
1. 5/3 and 3/5 are completely different fractions and when you switch the denominator and the numerator you get a different fraction: 5/3 = 1 2/3, 3/5
2. If you solve both of them, they are equal because 7-7 = 7-7
3. This is equal due to the associative addition property, which means that when the addition of three or more numbers, the total/sum will be the same, even when the grouping of addends are changed.

what is the measure of ∠x?
From figure we have , ∠GFH = 80° and ∠HGF = 60° , ∠GFH = 40° and ∠GFE = x°
Now,
In ∆HGF
Since Sum of the angles of a triangle is 180° :
∠GFH + ∠HGF + ∠GFH = 180°
80° + 60° + 40° = 180°
14° + 40° = 180°
54° = 180° ………..(1)
∠GFH + ∠GFE = 180° [Linear pair]
80° + x° = 180°
x° = 180°-80°
x° = 100°
Hence the value of ∠x is 100°
Among the given options option (D) 100° is correct.

Solve: x²+5x-6 = 0
Answer please
Given that:
x² + 5x - 6 = 0
Here we see that,
→ Product of coefficient of x² and constant term = 1 × 6 = 6
→Difference of the constant term and the coefficient of x² = 6 - 1 = 5
Now the given equation can be written as,
⇛x² + 6x - 1x - 6 = 0
(Here we simply applied the correc sign and splitted the middle term in two terms)
Now let's take the common terms
⇛x(x + 6) - 1(x + 6) = 0
On grouping we get,
⇛(x - 1)(x + 6) = 0
Here either (x - 1) = 0 or (x + 6) = 0 since the product is zero so anyóne of the terms should be zero.
⇛(x - 1) = 0 or (x + 6) = 0
⇛x - 1 = 0 or x + 6 = 0
⇛x = 1 or x = -6
Here we got two solutions of the equations. This means thet are in correct form.
Answer: The value of X is 1 or -6.
