To solve for V in the equation C = Q/V, you need to multiply both sides of the equation by V and then divide both sides by C.
Explanation:To solve the equation C = Q/V for V, we need to isolate V on one side of the equation. We can do this by multiplying both sides of the equation by V. This gives us CV = Q. To solve for V, we divide both sides of the equation by C. Therefore, V = Q/C.
WILL MARK BRAINLIEST Harry had $32. He spent all the money on buying 3 notebooks for $x each and 4 packs of index cards for $y each. If Harry had bought 5 notebooks and 5 packs of index cards, he would have run short of $18. A student concluded that the price of each notebook is $5 and the price of each pack of index cards is $1. Which statement best justifies whether the student's conclusion is correct or incorrect? The student's conclusion is incorrect because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 50 is (8, 2). The student's conclusion is incorrect because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 18 is (8, 2). The student's conclusion is correct because the solution to the system of equations 3x + 4y = 32 and 5x + 5y = 18 is (5, 1). The student's conclusion is correct because the solution to the system of equations 3x − 4y = 32 and 5x − 5y = 50 is (5, 1).
if the tax that you pay when you purchase an item is 12% of the sale price, write an expression that gives the tax on the item with a price p. write another expression that gives the total price ofthe item, including tax.
- what operations are involved in th expression you wrote
-determine the total price, including tax, of an item that costs 75.
-explain how the order of operation helped you solve this problem.
The tax on an item of price p is calculated as 0.12p and the total price is p + 0.12p. On calculating for an item that costs 75, the total cost with tax is 84. The order of operations (PEMDAS/BODMAS) was used to solve the problem accurately
Explanation:The tax on the item with a price p can be given by the expression 0.12p, using the operation of multiplication. The total price of the item, including tax would be p + 0.12p. This is done by using both addition and multiplication operations.
To determine the total price, including tax, of an item that costs 75, we substitute 75 for p in the second expression: 75 + 0.12*75 = 75 + 9 = 84. Therefore, an item that costs 75 before tax would cost 84 with tax.
Order of operations is important in this problem to ensure accurate calculations. According to PEMDAS/BODMAS rules (Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction), multiplication should be carried out before the addition, hence why 0.12*75 was calculated before adding the result to the initial cost of the item (75).

The taxation on an item with a price tag of 'p' can be represented as 0.12p. The total cost, counting tax, is depicted as 1.12p. Applying these expressions, an item priced at 75 would cost 84 including the 12% tax.
Explanation:The tax on an item with a price p can be expressed as 0.12p. This is because 12% is equivalent to 0.12 in decimal form. To find the total price of the item, including tax, you would add the original price (p) to the tax (0.12p). This can be written as p + 0.12p, or simplified further to 1.12p.
The operations involved in these expressions include multiplication and addition. To determine the total price, including tax, of an item that costs 75, you would plug in 75 for p in the total price expression, 1.12p. This works out to 1.12 * 75 = 84. The order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction) dictates that you perform multiplication before addition in the total price expression. Since there are no parentheses or exponents, you would multiply 0.12 by p (or the price of the item), and then add that result to p, to find the total price including tax.

A rock is kicked horizontally at 15 m/s from a hill with a 45degree slope. How long does it take for the rock to hit the ground?
Final answer:
The rock takes 2 seconds to hit the ground.
Explanation:
In order to find the time it takes for the rock to hit the ground, we can analyze the vertical motion of the rock. Since the rock is kicked horizontally, its initial velocity in the vertical direction is zero. The acceleration due to gravity is -9.8 m/s^2.
Using the equation h = ut + (1/2)gt^2, where h is the height, u is the initial velocity, g is the acceleration due to gravity, and t is the time, we can plug in the values to find the time.
Since the rock is kicked horizontally, the initial velocity in the vertical direction (uy) is zero, so the equation becomes h = (1/2)gt^2. We know that h = 0 since the rock is at the ground, and g = -9.8 m/s^2. Plugging these values into the equation, we get 0 = (1/2)(-9.8)t^2.
Solving for t, we find that t = 0 or t = 2 seconds. Since time cannot be negative, the rock takes 2 seconds to hit the ground.

Step-by-step explanation:
A standard deck of 52 playing cards contains 13 cards in each of four suits: diamonds, hearts, clubs, and spades. Two cards are chosen from the deck at random. What is the approximate probability of choosing one club and one heart?
The approximate probability of choosing one club followed by one heart from a standard deck of 52 playing cards is 5.9%.
The student's question pertains to the calculation of the probability of choosing one club and one heart from a standard deck of 52 playing cards. We start by recognizing that there are 13 clubs and 13 hearts in the deck, with each of the four suits represented equally.
Firstly, the probability of choosing a club (P(club)) is 13/52. After a club is chosen, there are 51 cards left in the deck. The number of hearts remains the same at 13 (since a club was chosen first). So, the probability of then picking a heart (P(heart)) is 13/51.
The two events, choosing a club and then a heart, are dependent events because the outcome of the second event depends on the outcome of the first. Hence, to find the combined probability, we multiply the probabilities of each event.
The probability of choosing one club followed by one heart is therefore P(club) imes P(heart) = (13/52) imes (13/51), which simplifies to approximately 0.059, or 5.9%.
a 14 foot ladder is leaning against a building. the ladder makes a 45 degree angle with the building. how far up the building does the ladder reach?
Using the sine function and known angle and ladder length, the distance up the building the ladder reaches is \(7\sqrt{2}\) feet.
The correct answer is option C) \(7\sqrt{2}\) feet.
To find how far up the building the ladder reaches, we can use trigonometric functions, specifically the sine function since we have the angle and the length of the ladder.
Given:
- Length of the ladder (hypotenuse) = 14 feet
- Angle with the building = 45 degrees
Let [tex]\(x\)[/tex]be the distance up the building that the ladder reaches.
Using the sine function [tex](\(\sin\))[/tex] in a right triangle:
[tex]\[ \sin(\theta) = \frac{\text{opposite}}{\text{hypotenuse}} \][/tex]
Substituting the known values:
[tex]\[ \sin(45^\circ) = \frac{x}{14} \][/tex]
Since [tex]\(\sin(45^\circ) = \frac{\sqrt{2}}{2}\),[/tex] we have:
[tex]\[ \frac{\sqrt{2}}{2} = \frac{x}{14} \][/tex]
To solve for [tex]\(x\),[/tex] multiply both sides by 14:
[tex]\[ x = 14 \times \frac{\sqrt{2}}{2} \][/tex]
[tex]\[ x = 7\sqrt{2} \, \text{feet} \][/tex]
Therefore, the ladder reaches [tex]\(7\sqrt{2}\)[/tex] feet up the building.
Therefore the correct answer is option C) [tex]\(7\sqrt{2}\)[/tex]feet.
The question probable may be:
A 14 foot ladder is leaning against a building. The ladder makes a 45 degree angle with the building. How far up the building does the ladder reach?
A. 7 feet
B. 28sqrt(2) feet
c. 7sqrt(2) feet
D. 14sqrt(2) feet.
In ELECTRONICS, the total resistance to the flow of electricity in a circuit is called the impedance, Z. Impedance is represented by a complex number. The total impedance in a series circuit is the sum of individual imepedances. The impedance in one part of a circuit is Z1 = 3 + 4i. In another part of a circuit, the impedance is Z1 = 5 - 2i. What is the total impedance of the circuit?
The total impedance of the circuit is 8 + 2i.
Explanation:The total impedance in a series circuit is the sum of the individual impedances. To find the total impedance of the circuit, add the real parts and imaginary parts separately. In this case, Z1 = 3 + 4i and Z2 = 5 - 2i. So, the total impedance Zt = (3 + 5) + (4 - 2)i. Simplifying this, Zt = 8 + 2i.

Solve: log2 (x) +log2(x+7) =3
(2 is the base) ...?
Final answer:
To solve the equation log2 (x) + log2(x+7) = 3, you can combine the logarithmic terms using the property log(a) + log(b) = log(a*b). By applying this property and solving the resulting quadratic equation, we find that x = 1.
Explanation:
To solve the equation log2 (x) + log2(x+7) = 3, we need to combine the logarithmic terms using the property log(a) + log(b) = log(a*b). Applying this property, we get log2 (x*(x+7)) = 3. Next, we can rewrite this equation in exponential form as 2^3 = x * (x+7). Simplifying further, we have 8 = x^2 + 7x. Rearranging the equation, we get a quadratic equation x^2 + 7x - 8 = 0. Solving this quadratic equation, we find that x = -8 or x = 1. However, since the logarithm of a negative number is undefined, the solution is x = 1.

Sarah is driving her car very smoothly from
Austin to Dallas one day. At 6:00 pm she is
travelling at 20 mph, while 25 minutes later
she is travelling at 40 mph.
Calculus tells us that at some time between
6:00 pm and and 6:25 pm her acceleration is
exactly x mph/h. Determine x.
The acceleration (x) is approximately 48 mph/hr, determined by dividing the change in velocity (20 mph) by the change in time (0.41667 hr).
Explanation:The subject of this problem is acceleration, which in this context refers to the rate at which Sarah increased her speed during a particular period of time. Here, the change in speed was from 20 mph to 40 mph, a difference of 20 mph. The time over which this change occurred was 25 minutes, but since acceleration is usually measured in hours, we need to convert this to 25/60 = 0.4167 hours.
The formula for acceleration is change in speed/ change in time.
Therefore, to calculate the acceleration, we divide the change in speed (20 mph) by the time (0.4167 hr) to get x = 20 mph / 0.4167 hr = 47.99 mph/hr or approximately 48 mph/hr, which is the acceleration.
