Answer:
29.24 grams
Step-by-step explanation:
It is given that,
Rachel's chocolate bar is 43% cocoa
The weight of the chocolate bar is 68 grams
We need to find how many grams of cocoa does it contain. It means it will contain 43% of 68 grams. It can be solved as follows :
[tex]C=\dfrac{43}{100}\times 68\\\\C=29.24\ \text{grams}[/tex]
Hence, it will have 29.24 grams of cocoa.

2(x+3)=x-4 what is x?
Answer:
x = - 10
Step-by-step explanation:
2(x + 3) = x - 4
2x + 6 = x - 4
2x - x = - 4 - 6
x = - 10

the 3 is being canceled out by the positive, because 3-3=0 therefore it's just canceled out, leaving you with x=2.
The result of adding a complex number to its conjugate is “an integer/a pure imaginary number/a real number/a whole number” and the result of subtracting a complex number from its conjugate is “an integer/a real number/a pure imaginary number/a whole number”
Answer:
If Z is a complex number:
Z = a + b*i
where a and b are real numbers, and i is an imaginary number.
Then "a" is the real part.
"b*i" is the imaginary part.
The conjugate of Z is:
Zc = a - b*i
So the sign of the imaginary part changes.
Then:
Sum:
Z + Zc = (a + bi) + (a - bi) = 2*a + 0 = 2*a
and remember that a is a real number, then 2*a is also a real numer.
The correct answer is "A real number".
Difference:
Z - Zc = (a + bi) - (a - bi) = 2b*i
and this is a pure imaginary number, so here the correct answer is: "a pure imaginary number"
Answer: a pure imaginary number
explanation:
The sum of a complex number and its conjugate will always be two times the real part of that complex number.
Z=a+b*i
where a and b are real numbers, and i is an nonexistent number.
Then a is the real part.
"b*i" is the imaginary part.
The connection of Z is:
Zc = a - b*i
So the sign of the imaginary part changes.
Sum:
Z + Zc = (a + bi) + (a - bi) = 2*a + 0 = 2*a
and remember that a is a real number, then 2*a is also a real number.
The correct answer is "A real number".
Difference:
Z - Zc = (a + bi) - (a - bi) = 2b*i

Jasmine spends exactly £120 on three types of plants: poisoned ivy, deadly nightshade and triffids. Poisoned ivy plants cost £2 each, deadly nightshade plants cost £9 each and triffids cost £12 each. She buys twenty plants in total, including at least one of each type. How many triffids did she buy?
Answer:
9/5
Step-by-step explanation:
2×9×12=216 so216/120 =9/5
Jasmine bought approximately 4 triffids.
We have,
We know that Jasmine bought a total of twenty plants and that she purchased at least one of each type.
Let's assume she bought x triffids.
From the given information, we can determine the number of poison ivy plants and deadly nightshade plants she bought:
Number of poisoned ivy plants = Total plants - (Number of deadly nightshade plants + Number of triffids)
Number of poisoned ivy plants = 20 - (1 + x) = 19 - x
Number of deadly nightshade plants = Total plants - (Number of poisoned ivy plants + Number of triffids)
Number of deadly nightshade plants = 20 - (1 + (19 - x)) = 20 - (20 - x) = x
We can now set up an equation based on the total amount Jasmine spent:
Total cost = (Number of poisoned ivy plants * Cost per poisoned ivy plant) + (Number of deadly nightshade plants * Cost per deadly nightshade plant) + (Number of triffids * Cost per triffid)
£120 = (19 - x) * £2 + x * £9 + x * £12
Simplifying the equation:
£120 = £38 - £2x + £9x + £12x
£120 = £38 + £19x
£82 = £19x
Dividing both sides of the equation by £19:
£82/£19 = x
x ≈ 4.32
Since we can't have a fractional number of plants, we'll round down to the nearest whole number.
Therefore,
Jasmine bought approximately 4 triffids.

Answer:
[tex]x=5[/tex]
Step-by-step explanation:
To solve for x, we can use the Exterior Angle Theorem.
The Exterior Angle Theorem states that the exterior angle is equivalent to the sum of the two opposite, interior angles.
So, we can write the following equation:
[tex](6+25x)=(44)+(18x-3)[/tex]
Now, we just have to solve for x.
On the right, let's subtract. So:
[tex]6+25x=18x+41[/tex]
Now, let's subtract 18x from both sides. This gives:
[tex]6+7x=41[/tex]
Now, let's subtract 6 from both sides. This will yield:
[tex]7x=35[/tex]
And, finally, let's divide both sides by 7, giving us:
[tex]x=5[/tex]
And we're done!
We can use the Exterior Angle Theorem.
6 + 25x = 44 + 18x - 3
6 + 25x = 18x + 41
25x = 18x + 35
7x = 35
x = 5

if the selling price of 16 water bottles is equal to the cost price of 17 water bottles find the gain percent earned by the dealer
Answer:
let cp of 17 water bottle is x
cp of 1 water bottle = x/17
from the question
sp of 16 water bottles = x
sp of 1 water bottle = x/16
profit = sp -cp
= x/16 - x/17
= x/272
profit % = profit /cp * 100%
= (x/272)/ (x/17) * 100%
= 6.25%
la edad de josé y beatriz están en la relacion de 5 a4 . si dentro de 3 años la suma de ambas edades seran 60 años , ¿ cual es la edad de beatriz ?
Answer:
La edad actual de Beatriz es de:
30 años
Step-by-step explanation:
Planteamiento:
5e = 4b
(e+3) + (b+3) = 60
e = edad actual de José
b = edad actual de Beatriz
Desarrollo:
de la segunda ecuación del planteamiento:
e + b + 6 = 60
e + b = 60 - 6
e + b = 54
e = 54 - b
sustituyendo este último valor en la primer ecuación del planteamiento:
5(54-b) = 4b
5*54 + 5*-b = 4b
270 - 5b = 4b
270 = 4b + 5b
270 = 9b
b = 270/9
b = 30
e = 54 - b
e = 54 - 30
e = 24
Comprobación:
5e = 4b
5*24 = 4*30 = 120
