Lara makes birdseed by mixing peanuts and sunflower seeds in a 2:3 ratio. The peanuts costs 3p per 10g and the sunflower seeds cost 9p per 10g. Lara sells the birdseed £1 per 100g portion.
How much profit does Lara make on each portion? Give your answer in pence.
Step by step explanation plssss tqsm.
Answer:
Lara will do a profit of 34 pence by 100 grams of birdseed.
Step-by-step explanation:
The given ratio means that there are 2 grams of peanuts and 3 grams of sunflower per each 5 grams of birdseed. Now, we obtain the amount required of peanuts and sunflower for 100 grams of birdseed by simple rule of three:
Peanuts
[tex]x = \frac{100\,g}{5\,g}\times 2\,g[/tex]
[tex]x = 40\,g[/tex]
Sunflower
[tex]y = \frac{100\,g}{5\,g}\times 3\,g[/tex]
[tex]y = 60\,g[/tex]
If we know that 10 grams of sunflower cost 9 pence and 10 grams of sunflower cost 3 pence, then the total cost of production of 100 grams portion:
[tex]C = \left(\frac{0.03\,GBP}{10\,g} \right)\cdot (40\,g)+\left(\frac{0.09\,GBP}{10\,g} \right)\cdot (60\,g)[/tex]
[tex]C = 0.66\,GBP[/tex]
And the profit done by Lara is:
[tex]\Delta C = 1\,GBP - 0.66\,GBP[/tex]
[tex]\Delta C = 0.34\,GBP[/tex]
Lara will do a profit of 34 pence by 100 grams of birdseed.

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

Answer:
A. 3.7, because |3.7| = 3.7
Step-by-step explanation:
What the question is referring her by magnitude is units away from 0. 3.7 is 3.7 units away from 0, which is the same thing as the absolute value of 3.7. And since absolute value is always positive, C is already out. D is also out as the value doesn't change. B's reason contradicts the answer, so it is also wrong. This leaves A (3.7, because |3.7| = 3.7) as our answer.
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

Answer:
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
