Según la reacción de abajo, ?Cuantos gramos ácido sulfhídrico se desprenden, cuando reaccionan completamente 5 moles de sulfuro niquélico? Los pesos atómicos son: Ni: 58.7 uma, S: 32 uma, O: 16 uma, H: 1 uma
Ni2S3 + 6 H2O ---> 2 Ni(OH)3 + 3 H2S
Answer:
510g H2S
Step-by-step explanation:
En esta pregunta, se nos pide calcular la masa de H2S emitida cuando 5 moles de sulfuro de níquel reaccionan completamente con el agua.
De la ecuación equilibrada, podemos ver que 1 mol de sulfuro de níquel produjo 3 moles de sulfuro de hidrógeno Por lo tanto, 5 moles de sulfuro de níquel producirán = 5 * 3 moles = 15 moles de sulfuro de hidrógeno
Matemáticamente, la masa se puede calcular multiplicando el número de moles por masa molar La masa molar de H2S es 2 (1) + 32 = 34 g / mol La masa en gramos así producida = 15 mol * 34g / mol = 510g
Chuy purchased a used truck for
$11,500. According to an online
vehicle website, his truck will
depreciate, or lose value, at a rate of
5.5% each year. What function, d(x),
represents the value of Chuy's truck
x years after its purchase?
Answer:
d(x) = 11500*0.945^x
Step-by-step explanation:
Chuy's truck loses 5.5% of its value each year. That means each year:
(current worth of truck) = (previous year's worth) - (previous year's worth)*5.5%
The current worth is also equivalent to (previous year's worth)*94.5%.
After one year, the worth is (first year)*94.5%.
After two years, the worth is ((first year)*94.5%)*94.5%.
Note that each year, the original value of the car is multiplied by 94.5% to get the current worth. Recall also that 94.5% = 0.945.
d(x) = 11500*0.945^x, where 11500 is the original price.
Final answer:
The function representing the value of Chuy's truck x years after purchase, given a depreciation rate of 5.5% annually, is [tex]d(x) = 11500(1 - 0.055)^x[/tex]. This formula calculates the truck's decreasing value over time.
Explanation:
The question asks for the function d(x), which represents the value of Chuy's truck x years after its purchase, given it depreciates at a rate of 5.5% annually. The general formula to calculate depreciation using a percentage rate is
[tex]V = P(1 - r)^x[/tex]
where V is the future value of the item, P is the initial purchase price, r is the annual depreciation rate (in decimal form), and x is the number of years.
In this case, Chuy's truck was purchased for $11,500, and it depreciates at a rate of 5.5% per year. Substituting these values into the formula, we get the function for the value of the truck as-
[tex]d(x) = 11500(1 - 0.055)^x[/tex]
This equation allows us to determine the truck's value at any amount of years after the purchase.

What is the size of the angle, below?
To find the size of an angle, one can use the small-angle approximation, which for small angles allows one to estimate the angle based on linear size and distance when measured in radians. The thumb method suggests a thumb at arm's length subtends an angle of 1 degree.
Explanation:To address the question about the size of a given angle, we must consider several mathematical concepts related to angles and their measurement. A key method of estimating angles involves using the small-angle approximation, which relates the linear size of an object to its angular size when viewed from a certain distance.
This approximation states that for small angles, the tangent of the angle is approximately equal to the angle itself when measured in radians. If we know the approximate width of an object, such as a thumb (1 cm) and use a comfortable viewing distance, Lo (\u2248 25 cm), we can estimate the angular size using this relationship.
The size of an angle can be described using different units, primarily degrees, arcminutes, and arcseconds, or radians. As part of learning about angles, students are taught to convert between these units. Given the question's context, if a thumb is estimated to subtend an angle of 1 degree at arm's length, we would have a straightforward method to approximate the angle's size through observation.

Which number is a common factor of 116 and 40
Answer:
4
Step-by-step explanation:
[tex]116 = 2 \times 2 \times 29 \\ 40 = 2 \times 2 \times 2 \times 5 \\ common \: factors = 2 \: \: 2 \\ common \: factors \: of \: 116 \: and \: 40 \\ = 2 \times 2 = 4[/tex]
The numbers 116 and 40 share common factors of 1, 2, and 4, with 4 being their greatest common factor.
The common factor of 116 and 40 can be found by identifying the numbers that divide both without leaving a remainder. To do so, we factorize both numbers:
116 = 2 x 2 x 29 = 2² x 2940 = 2 x 2 x 2 x 5 = 2³ x 5Next, we find the common factors by looking at the prime factors they share. Both numbers have the prime number 2 as a factor. The highest power of 2 that divides both numbers is 2², which is 4. Therefore, the greatest common factor (GCF) is 4. However, since we are looking for a common factor, not necessarily the greatest, 2 and 1 are also common factors of 116 and 40.

A handicap ramp that is 25 feet long coves a ground distance of 22 feet. To the nearest degree, what is the angle of elevation of incline for the handicap ramp?
Answer:
28.36°
Step-by-step explanation:
The problem represents a right angled triangle as shown in the diagram below.
The length of the handicap ramp is 25 feet.
The side ground distance covered by the ramp is the adjacent of the angle of the triangle and it is 22 feet.
To find the angle of elevation of the incline, we apply SOHCAHTOA:
cos θ = adj / hyp
Therefore:
[tex]cos \alpha = 22 / 25\\\\cos \alpha = 0.88\\\\\alpha = cos^{-1} 0.88\\\\\alpha = 28.36^o[/tex]
The angle of elevation of the incline for the handicap ramp is 28.36°.

Step-by-step explanation:
Basically, we want to find the surface area of this cylinder.
The surface area of a cylinder is denoted by: A = 2πr² + 2πrh, where r is the radius and h is the height. However, note that the farmer only wants to paint the curved surface of the cylinder, so we don't want to include the 2πr² part that accounts for the two circular bases. Instead, we actually just want to find the value of 2πrh.
Here, we see that the diameter is 8 metres, so since the radius is half the diameter, we know that r = 8/2 = 4 metres.
We also see that the height is 6 metres, so h = 6.
Plug these numbers in:
2πrh
2π * 4 * 6 = 48π ≈ 150.8 m²
We see that each can of paint will cover 20 m², so divide 150.8 by 20 to find the number of cans we need:
150.8 ÷ 20 = 7.5 ≈ 8 cans
Each can costs £11.75, so multiply 8 by 11.75 to get the total cost:
11.75 * 8 = £94
The answer is £94.

The greater of two numbers is six more than 4 times the smaller. Their sum is 41. Find the number
Answer:
smaller number is 7
larger number is 35
Step-by-step explanation:
Let the smaller number be x
Given that greater number is 6 more than 4 times the smaller number.
If x is value of smaller number then 4 times the smaller number is 4*x= 4x
six more than 4 times the smaller number will be 6+4x.
Thus larger number is 6+4x
Sum of smaller and larger no is 41.
Substituting the value of smaller and larger number in sum we have
x+6+4x = 41
=> 5x+6 = 41
=> 5x = 41-6
=> 5x= 35
=>x = 35/5 = 7
Thus smaller number is x = 7
larger number = 4x+6 = 4*7+6 = 35
To find the two numbers, we can set up two equations and solve them using substitution and simplification. The smaller number is 7, and the larger number is 34.
Explanation:To solve this problem, we can set up two equations.
Let's call the smaller number 'x' and the greater number 'y'.
From the given information, we know that:
y = 4x + 6 (Equation 1)
x + y = 41 (Equation 2)
Now, we can substitute Equation 1 into Equation 2 to solve for 'x':
x + (4x + 6) = 41
Combining like terms, we have:
5x + 6 = 41
Next, subtracting 6 from both sides gives:
5x = 35
Finally, dividing both sides by 5 gives:
x = 7
So, the smaller number is 7.
Plugging this value back into Equation 1:
y = 4(7) + 6 = 34
Thus, the larger number is 34.

The owner of the Rancho Grande has 3,060 yd of fencing with which to enclose a rectangular piece of grazing land situated along the straight portion of a river. If fencing is not required along the river, what are the dimensions (in yd) of the largest area he can enclose?
Answer:
1170450 yd^2
Step-by-step explanation:
The first thing is to calculate the necessary perimeter, which would be like this:
2 * a + b = 3060
if we solve for b, we are left with:
b = 3060-2 * a
Now for the area it would be:
A = a * b = a * (3060-2 * a )
A = 3060 * a -2 * a ^ 2
To maximize the area, we calculate the derivative with respect to "a":
dA / da = d [3060 * a -2 * a ^ 2
]/gives
dA / day = 3060 - 4 * a
If we equal 0:
0 = 3060 - 4 * a
4 * a = 3060
a = 3060/4
a = 765 and d
Therefore b:
b = 3060 - 2 * a = 3060 - 1530 = 1530
A = a * b
A = 765 * 1530
A = 1170450 and d ^ 2
Final answer:
To find the largest area the owner of the Rancho Grande can enclose, we set up an equation using the perimeter of the rectangular land and the available fencing. By solving the equation and finding the maximum point of a quadratic equation, we determine that the dimensions of the largest area are L = 765 yd and W = 1,530 yd.
Explanation:
To find the dimensions of the largest area the owner of the Rancho Grande can enclose, we need to consider that the rectangular grazing land is situated along the straight portion of a river. Since fencing is not required along the river, the owner can use the available fencing to enclose the other three sides of the rectangular piece of land.
Let's assume the length of the rectangular piece of land is L and the width is W.
Since there are three sides that require fencing, the perimeter of the rectangular piece of land is given by:
P = L + W + L = 2L + W
According to the information provided, the owner has 3,060 yd of fencing available. Therefore, we can write the equation:
2L + W = 3,060
To maximize the area, we need to solve this equation for one variable and substitute it back into the area formula, A = L * W. Let's solve for L:
2L = 3,060 - W
L = (3,060 - W)/2
Substituting L in the area formula:
A = ((3,060 - W)/2) * W
Finally, we can maximize the area by finding the maximum point of the quadratic equation:
A = -0.5W^2 + 1,530W
The maximum point of a quadratic equation in the form A = ax^2 + bx + c occurs at x = -b/2a.
Comparing the quadratic equation to A = -0.5W^2 + 1,530W, we have:
a = -0.5
b = 1,530
Substituting these values into x = -b/2a:
W = -1,530 / (2 * -0.5)
Calculating W:
W = 1,530 / 1
W = 1,530
Now, substituting W back into the equation for L:
L = (3,060 - 1,530) / 2
L = 1,530 / 2
L = 765
Therefore, the dimensions of the largest area the owner of the Rancho Grande can enclose are L = 765 yd and W = 1,530 yd.

E DGENUITY
Answer: 119
Step-by-step explanation: got it right
In the given figure, measure of angle A is 61°, measure of angle B is 119° and measure of angle C is 62°.
From the given triangle triangle, exterior angle to the angle C is 118°.
We know that, sum of two adjacent angles is 180°.
Here, ∠C+118°=180°
∠C=180°-118°
∠C=62°
By using exterior angle theorem of triangle, we get
∠A+57°=118°
∠A=118°-57°
∠A=61°
So, ∠A+∠B=180° (Adjacent angles)
61°+∠B=180°
∠B=180°-61°
∠B=119°
Therefore, in the given figure, measure of angle A is 61°, measure of angle B is 119° and measure of angle C is 62°.

Benjamin started her walk from the front door of her ground floor apartment. She walked 6 meters to the corner of the building and then turned the corner and walked 10 meters to her friend's apartment.
Answer:
4 meters.
Step-by-step explanation:
Benjamin has walked two legs of a right triangle, so you can connect her two movements with a line if you were sketching the situation.. The displacement is the objects overall change in position in relation to its origin, so in your case, Benjamin's apartment. While the total distance adds up regardless of her position.
So, the total distance Benjamin walked is 10m + 6m = 16m
Her displacement can be found by your best friends, the Pythagorean Theorem: 10m ^2 + 6m ^2 = delta x^2 (or displacement squared).. giving you a displacement of 11.66, or 12 m.
The difference between the distance she walked and her displacement is 4 meters.

Rachel deposited $3000 in an account in the Merrick National Bank, earning 1.5% interest, compounded monthly. She made no deposits or withdrawals. Which equation can be used to find A, her account balance after t years?
Answer:
The expression that should be used to find her ballance over the years is "A = 3000*(1.125)^(12*t)".
Step-by-step explanation:
We can use the compounded interest formula to calculate her balance over t years. The formula is shown below:
A = C*(1 + r/n)^(n*t)
Where A is the final value, C is the initial value, r is the interest rate, n is the rate at which the account is compounded over a year and t is the total elapsed time in years. Applying the data from the problem we have:
A = 3000*(1 + 1.5/12)^(12*t)
A = 3000*(1 + 0.125)^(12*t)
A = 3000*(1.125)^(12*t)

Laney builds a tower with wooden cubes. The bottom cube's edges are 8 centimeters long. The middle cube's edges are 2 centimeters shorter than the bottom cube. The top cube's edges are 2 centimeters shorter than the middle cube. What is the total volume of the cubes in the tower?
Answer: The total volume of the the cubes in the tower is 792 cubic centimetres (792 cm³)
Step-by-step explanation: We shall call the volume of the cube at the bottom VB, the volume of the cube at the middle VM, and the volume of the cube at the top VT. The tower is made up of cubes at different levels and at the bottom the cube measures 8 centimetres. The cube at the middle measures 2 cm less than the bottom cube, hence middle cube equals 8 minus 2 which equals 6 cm. The top cube measures 2 cm less than the middle cube, hence the top cube equals 6 minus 2 which equals 4 cm. The volume of each cube is given as;
Volume = L³
The length of a cube measures the same on all sides, that is, length, width and height. The length on all sides therefore of the bottom cube is 8 cm. The volume equals;
VB = 8³
VB = 512 cm³
The length on all sides of the middle cube is 6 cm (measures 2 cm shorter than the bottom cube). The volume of the middle cube equals;
VM = L³
VM = 6³
VM = 216 cm³
The length on all sides of the top cube is 4 cm (measures 2 cm shorter than the middle cube). The volume of the top cube equals;
VT = L³
VT = 4³
VT = 64
From the calculations shown, the total volume of the cubes in the tower is given as;
Total volume = VB + VM + VT
Total volume = 512 + 216 + 64
Total volume = 792 cm³
Total volume is 792 cubic centimetres.
Answer: The total volume of the cubes is 792 cm^3
Step-by-step explanation:
We have 3 cubes here.
And remember that the volume of a cube is equal to the length of one of the edges at the power of 3.
So for the bottom cube, we have that the edges are 8cm long, so the volume of this cube is:
V1 = 8cm^3 = 512cm^3
The edges of the next cube are 2cm shorter, so the edges are 6cm long.
Then the volume is:
V2 = 6cm^2 = 216cm^3
The top cube's edges are 2 cm shorter than the previous one, so the length of these edges is 4cm, then the volume is:
V3 = 4cm^3 = 64cm^3
Now, the total volume is equal to:
V = V1 + V2 + V3 = 512cm^3 + 216cm^3 + 64cm^3 = 792 cm^3
