The area of a rhombus is 16 cm 2 . If the length of one diagonal is 4 cm, find the
length of the other diagonal.
Answer: The length of the other diagonal is 8 cm.
Step-by-step explanation:
Area of rhombus = [tex]\frac{pq}{2}[/tex]
[tex]\frac{4q}{2} =16\\[/tex]
[tex]4q = 32\\q = 8\\[/tex]
The length of the other diagonal is 8 cm.

What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
We have [y] varies directly with [x] and y doubles then x.
The general equation of a straight line can also be used to represent proportional relationship when [c] = 0.
y = mx + c
y = mx + 0
y = mx
m = y/x
where [m] is constant of proportionality.
A/C to question -
y = 2x
Here, the constant of proportionality is 2.
Therefore, the constant of proportionality is 2.

Answer:
50
Step-by-step explanation:
Since 140° is on the outside, the angle next to it would be 40°.
Also a triangle = 180°
40° + 90° = 130°
180° - 130° = 50°
Thus meaning x = 50°
Answer:
x = 50°
Step-by-step explanation:
- the angle at the top is shown as a right angle so it is 90°
-the 140° angle and the angle next to it are 180° together so let's name the other angle z
z+140=180
z=180-140=40°
- a triangle's angles in total have 180°
x+y+z= 180°
x+90°+40°=180°
x+130 =180
x= 180-130 = 50°

3х – 6 = 4 (2 - 3х) — 8x
what is x?
Answer:
x = 2/5 or 0.4
Step-by-step explanation:
3x - 6 = 4(2 - 3x) - 8x
distribute
3x - 6 = 4*2 - 4*3x - 8
3x - 6 = 8 - 12x - 8
combine like terms
3x - 6 = -12x
add 12x to both sides of the equation
3x - 6 + 12x = -12x + 12x
3x - 6 + 12x = 0
15x - 6 = 0
add 6 to both sides of the equation
15x - 6 + 6 = 0 + 6
15x = 6
divide both sides of the equation by 15
15x/15 = 6/15
x = 6/15
x = 2/5
x = 0.4

The product of −2 and a number x is greater than 30.
An inequality is
.
The solution of this inequality is
.
Answer:
-2(x)>30
An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.
x<-15
Step-by-step explanation:
-2(x)>30 means to divide -2 on both sides which is -15.
x>-15
Next you switch the inequality because you multiplied by a negative:
x<-15
3. Problema 2: Suponga que un fabricante de radios tiene la función de costo total C (x) = 43x + 1850 dólares y la función de ingreso R (x) = 80x dólares. Donde "x" es el número de radios fabricados y vendidos. Halle:
Responder:
$ 11,137
Explicación paso a paso:
Como no se nos dice qué encontrar, también podemos encontrar el beneficio obtenido por la venta de 351 unidades de radio.
Dado
Función de costo C (x) = 43x + 1850
Función de ingresos R (x) = 80x
Obtener la función de ganancias
P (x) = R (x) - C (x)
P (x) = 80x - (43x + 1850)
P (x) = 80x - 43x - 1850
P (x) = 37x - 1850
Si se fabrican 351 radios, la ganancia obtenida se calculará como se muestra a continuación:
P (351) = 37 (351) - 1850
P (351) = 12,987-1850
P (351) = 11,137
Por lo tanto, la ganancia obtenida de las ventas de 351 radios es de $ 11,137

I would say A because 6:3 can only equal 1/3.
Step-by-step explanation:
It would help if you formatted a bit better though. As the choices are not clear. ^^
The probability of getting numbers whose sum is a multiple of three is,
⇒ 1 / 3
Since, The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Here, We have;
There are 48 possible outcomes in this situation, and of those outcomes, the ones whose sums are a multiple of three are;
12, 21, 15, 51, 24, 42, 33, 18, 27, 36, 63, 45, 54, 48, 57, and 66.
So, that is 16 out of 48 possibilities,
⇒ 16/48,
⇒ 1/3.
Thus, The probability of getting numbers whose sum is a multiple of three is,
⇒ 1 / 3
