Answer:
x+x=8
that's mean: 2.x/4 + 4.x/1 = 18/1
we find at least a common multiple of 4 and multiply the units by 4
2x + 16x = 72
18x = 72/:18
x = 4
Answer: 7
suppose: the smaller number is a
the larger number is b
because The sum of two numbers is 8 => a + b = 8 (1)
four times the smaller number is added to two times the larger number, the result is 18 => 4a + 2b = 18 (2)
(1)(2) => a + b = 8
4a + 2b = 18
<=> a = 1
b = 7
=> the larger number is 7

Step-by-step explanation:
Apparently, you want to evaluate ...
0.1m +8 -12n
for m = 30 and n = 1/4.
Put the numbers where the corresponding variables are and do the arithmetic.
= 0.1×30 +8 -12×(1/4) = 3 + 8 -3

How to divide 7 divided by 7/4
Answer:
4
Step-by-step explanation:
7÷7/4
in these cases we multiply by the reciprocal
7× 4/7
7 and 7 can be cancelled with each other
the remaing answer = 4
Answer:
1/4
Step-by-step explanation:
First, since the numerator is 7 you want to see how many times you can divide that.
So, you can only divide 7 by 7 1 time so that turns into 1.
Hence, your numerator is now 1 and denominator stays the same so its..

In a unit circle, ø= 90°. Identify the terminal point and sin Ø.
A. Terminal point: (0,1); sin ø= 1
B. Terminal point: (1,0); sin ø=0 C. Terminal point: (1, 0); sin ø=1
D. Terminal point: (0,1); sin ø=0
Answer:
Terminal point: (0, 1); sinФ = 1 ⇒ A
Step-by-step explanation:
In the unit circle, Ф is the angle between the terminal side and the positive part of the x-xis.
The terminal point on the positive part of the x-axis is (1, 0),which means Ф = 0° or 360° and cosФ = 1, sinФ = 0The terminal point on the positive part of the y-axis is (0, 1),which means Ф = 90° and cosФ = 0, sinФ = 1The terminal point on the negative part of the x-axis is (-1, 0),which means Ф = 180° and cosФ = -1, sinФ = 0The terminal point on the negative part of the y-axis is (0, -1),which means Ф = 270° and cosФ = 0, sinФ = -1In a unit circle
∵ Ф = 90°
→ By using the 2nd rule above
∴ The terminal point is (0, 1)
∴ sinФ = 1
∴ Terminal point: (0, 1); sinФ = 1

Find four consecutive negative integers whose sum is -42
Answer:
-12, -11, -10 and -9 add up to -42
Step-by-step explanation:
We can solve this by expressing all four of those integers relative to the first one:
[tex]x + (x + 1) + (x + 2) + (x + 3) = -42\\4x + 6 = -42\\4x = -48\\x = -12[/tex]
so we know that the lowest one is -12, and the other three are sequentially higher value:
-12, -11, -10 and -9
Answer: -12, -11, -10, -9
Step-by-step explanation:
they all add up to -42

En una caja de cartón se empacan 400 latas de atún al acomodarlas resultan que caben 5 latas más a lo largo que a lo ancho y a lo alto caben 3 latas más que a lo ancho ¿Cuántas latas en total tocan el fondo de la caja?
Answer:
Hay 50 latas en total que tocan el fondo de la caja.
Step-by-step explanation:
Una caja de cartón es representada por un cuadrilátero, cuyas caras son rectángulos. Si la caja esta ocupada por completo, entonces la cantidad total de latas es representada por la siguiente expresión:
[tex]n_{V} = n_{w}\cdot n_{h}\cdot n_{l}[/tex] (1)
Donde:
[tex]n_{V}[/tex] - Total de latas de atún, adimensional.
[tex]n_{w}[/tex] - Cantidad de latas de atún a lo ancho de la caja, adimensional.
[tex]n_{h}[/tex] - Cantidad de latas de atún a lo alto de la caja, adimensional.
[tex]n_{l}[/tex] - Cantidad de latas de atún a lo largo de la caja, adimensional.
De acuerdo con el enunciado, tenemos las siguientes relaciones:
[tex]n_{V} = 400[/tex] (2)
[tex]n_{l} = n_{w} +5[/tex] (3)
[tex]n_{h} = n_{w}+3[/tex] (4)
Si aplicamos estas fórmulas a (1), tenemos el siguiente polinomio de tercer orden:
[tex]n_{w} \cdot (n_{w}+5)\cdot (n_{w}+3) = 400[/tex]
[tex]n_{w}\cdot (n_{w}^{2}+8\cdot n_{w}+15) = 400[/tex]
[tex]n_{w}^{3}+8\cdot n_{w}^{2}+15\cdot n_{w} -400 = 0[/tex]
Este polinomio se puede resolver por vía analítica por el Método de Cardano o por vía numérica, sus raíces son:
[tex]n_{w,1} = 5[/tex], [tex]n_{w,2} = -6.5+i\,6.144[/tex], [tex]n_{w,3} = -6.5-i\,6.144[/tex]
En consecuencia, la única solución válida es [tex]n_{w} = 5[/tex] y las variables restantes son por (3) y (4):
[tex]n_{l} = 10[/tex] y [tex]n_{h} = 8[/tex]
La cantidad de latas que tocan el fondo de la caja es igual al producto de la cantidad de latas a lo largo de la caja y la cantidad de latas a lo ancho de la caja, es decir:
[tex]n_{A} = n_{w}\cdot n_{l}[/tex] (5)
[tex]n_{A} = (5)\cdot (10)[/tex]
[tex]n_{A} = 50[/tex]
Hay 50 latas en total que tocan el fondo de la caja.
Solve the triangle with the law of sines
Answer:
see below
Step-by-step explanation:
We can use the law of sines
sin 80 sin B
--------------- = -------------
31 14
Using cross products
14 sin 80 = 31 sin B
14/31 sin 80 = sin B
.984807753 = sin B
Taking the inverse sin of each side
sin ^ -1 ( .444751888) = B
26.41 = B
The sum of the angles of a triangle is 180
A+B+C = 180
80 + 26.41 + C =180
106.41 + C = 180
C = 73.59
We can use the law of sines to find c
sin 80 sin 73.59
--------------- = -------------
31 c
c sin 80 = 31 sin 73.59
c = 31 sin 73.59 / sin 80
c = 30.20
AB = 30.20
