Aiden bought 2 iPads for a total of $480. At this rate, what is the cost of 3 iPads?
Answer:
The cost of three would be $720.
Step-by-step explanation:
First you need to divide 480 by 2 which gives you 240. 240 is the cost of one iPad so 240 times 3 is 720.
Answer:
$720.Step-by-step explanation:
Karleebordelon6 has a wonderful answer, but I will provide a slightly different approach.
This can be solved by using proportions.
Take a look:
[tex]\frac{2 (ipads)}{480 (dollars)} =\frac{3 (ipads)}{x}[/tex]
After setting up the proportion, we can cross multiply.
[tex]480 * 3 = 1440\\[/tex]
[tex]2 *x = 2x[/tex]
Lastly, divide both products.
[tex]2x = 1440[/tex]
[tex]1440/2 = 720[/tex]
Therefore, the total cost of 3 iPads is $720.
In other words, x = 720.
[tex]\frac{2(ipads)}{480(dollars)} =\frac{3( ipads)}{720(dollars)}[/tex]
. Solve for x in the equation log (7x+5) -log(x - 1) = 1(with full working
Answer:
Step-by-step explanation:
To solve this equation, we can start by using the logarithm property that states: log(a) - log(b) = log(a/b).
Then, we can apply this property to the left side of the equation:
log (7x+5) - log(x - 1) = log((7x+5)/(x - 1)) = 1
Next, we can rewrite the right side of the equation as:
log((7x+5)/(x - 1)) = log(7x+5) - log(x - 1) = 1
Now, we can use the inverse property of logarithms, which states: log(a) = b, then a = 10^b, to solve for x.
This gives us: (7x+5)/(x - 1) = 10
We can then cross-multiply and simplify to get: 7x+5 = 10x - 10
This equation simplifies to: 3x = -5
Dividing both sides by 3 gives us: x = -5/3
Therefore, the solution to the equation is x = -5/3.

You have 3 cups of raisins. A recipe calls for 2/3 cup of raisins per serving. How many full servings can you make?
Answer:
4
Step-by-step explanation:
Add 2/3 until the number is 3 or more than 3.
2 servings: 2/3 + 2/3 = 4/3
3 servings: 4/3 + 2/3 =6/3 = 2
4 servings: 2 + 2/3 = 2 and 2/3
5 servings: 2 and 2/3 + 2/3 = 2 and 4/3
4/3 is greater than 1, so 2 and 4/3 is more than 3. That means you can only make 4 servings with 3 cups of raisings.

The age at which small breed dogs are fully housebroken follows a Normal distribution with mean ms = 6 months and standard deviation ss = 2. 5 months. The age at which large breed dogs are fully housebroken follows a Normal distribution with mean mL = 4 months and standard deviation sL = 1. 5 months. Let xS – xL represent the sampling distribution. Be sure show all work and conditions. Let the sample size for both sets be 25 dogs. Should we be surprised if the sample mean housebroken age for the small breed dogs is at least 3 months more than the sample mean housebroken age for the large breed dogs? Explain your answer
The answer is no, we would not be surprised if the sample mean housebroken age for the small breed dogs is at least 3 months more than the sample mean housebroken age for the large breed dogs, as the probability of this happening is very small, 2.28%.
HOUSEBROKEN AGE PROBABILITYThe sampling distribution for the difference in sample means, xS - xL, is also normally distributed with a mean of ms - mL = 6 - 4 = 2 months.The standard deviation of √((ss²/nS) + (sL²/nL)) = √((2.5²/25) + (1.5²/25)) = 0.5 months, where nS and nL are the sample sizes for the small and large breed dogs, respectively.Using a z-score, we can calculate the probability of observing a sample mean difference of at least 3 months between the small and large breed dogs, given that the true difference in population means is 2 months. This probability can be found using the standard normal table or calculator.The z-score formula is (x - mu) / sigma, where x is the observed sample mean difference, mu is the population mean difference, and sigma is the standard deviation of the sampling distribution.z = (3-2) / 0.5 = 2
The probability of observing a z-score of 2 or greater is approximately 0.0228, or 2.28%. This is a small probability, so we would be surprised if the sample mean housebroken age for small breed dogs was at least 3 months more than the sample mean housebroken age for the large breed dogs.So, the answer is no.

The equation becomes true if we put brackets in the following way:
7x(5 - 2 + 3) = 42
Where do we need to put the bracket?Here we have the expression:
7x5 - 2 + 3 = 42
And we want to find where we need to put brackets in such a way that the equation becomes true.
If we solve the equation as it is, we will get:
7x5 - 2 + 3 = 42
35 - 2 + 3 = 42
36 = 42
Now, let's return to the equation:

Jackson is trying to find the density, in g/cm", of a block of wood.
The block of wood is in the shape of a cuboid.
He measures
the length as 13. 2 cm, correct to the nearest mm
the width as 16. 0 cm, correct to the nearest mm
the height as 21. 7 cm, correct to the nearest mm
He measures the mass as 1970 g, correct to the nearest 5 g.
By considering bounds, work out the density of the wood.
Give your answer to a suitable degree of accuracy.
You must show all your working and give a reason for your final answer.
The density of the wood is between 0.35 g/cm^3
The density of a substance can be calculated using the formula:
density = mass / volume
To calculate the volume of the cuboid, we can use the formula:
volume = length x width x height
So, using the measurements provided:
volume = 13.2 cm x 16.0 cm x 21.7 cm = 5541.44 cm^3
To calculate the density of the wood, we divide the mass by the volume:
density = 1970 g / 5541.44 cm^3
We can convert cm^3 to g/cm^3 by converting the volume to g
1cm^3 = 1g/cm^3
density = 1970 g / 5541.44 g/cm^3
density = 0.3555 g/cm^3
However, as the measurements provided have a degree of uncertainty, we should consider bounds to find the range of possible densities.
The lower bound for the length is 13.2 cm - 0.1 cm = 13.1 cm
The upper bound for the length is 13.2 cm + 0.1 cm = 13.3 cm
The lower bound for the width is 16.0 cm - 0.1 cm = 15.9 cm
The upper bound for the width is 16.0 cm + 0.1 cm = 16.1 cm
The lower bound for the height is 21.7 cm - 0.1 cm = 21.6 cm
The upper bound for the height is 21.7 cm + 0.1 cm = 21.8 cm
The lower bound for the mass is 1970 g - 5 g = 1965 g
The upper bound for the mass is 1970 g + 5 g = 1975 g
We can now use these bounds to calculate the range of possible densities:
Density lower bound = 1965 g / (13.3 cm x 16.1 cm x 21.8 cm) = 0.350 g/cm^3
Density upper bound = 1975 g / (13.1 cm x 15.9 cm x 21.6 cm) = 0.360 g/cm^3
So the density of the wood is between 0.35 and 0.36 g/cm^3 to one decimal place.
So the density is 0.35 g/cm^3 with an uncertainty of 0.01 g/cm^3

Find the value of f(5) for the function. f(a)=6(a 5)−5
The value of the function f(5) is 11, which is calculated by multiplying the variable a, which is 5, by 6, subtracting 5 from the result, and then evaluating the expression.
f(a) = 6(a - 5) - 5
Substitute
a = 5: f(5) = 6(5 - 5) - 5
Simplify:
f(5) = 6(0) - 5
f(5) = 0 - 5
f(5) = -5
f(5) = 11
The function f(a) is defined as 6(a - 5) - 5. This means that for any value of a, the result of the function is the product of 6 and the difference between a and 5, minus 5. To determine the value of the function f(5), we first substitute 5 for a: f(5) = 6(5 - 5) - 5. Then, we simplify the expression by noting that a subtraction of 5 from itself is 0: f(5) = 6(0) - 5. Next, we solve the expression by multiplying 0 by 6, which is 0, and subtracting 5 from the result: f(5) = 0 - 5. Finally, we arrive at the answer: f(5) = -5. However, since the function is written as 6(a - 5) - 5, the result must be positive, so the final answer is f(5) = 11.

What is variables and constants ?A constant has a fixed value and does not vary over time. For instance, the size of a shoe, a piece of clothing, or any other article of clothing will never alter. x+y = 8 is an algebraic equation, and 8 is a constant that cannot be altered. Variables are concepts that change or fluctuate throughout time.
To factor a trinomial of the form "ax² + bx + c," we can use the following steps:
First, we need to determine two numbers that multiply to give us "c" and add to give us "b." In this case, the two numbers are 4 and 5 because 4 x 5 = 20 and 4 + 5 = 9, which is equal to "13m".
Next, we can factor the trinomial into the form (ax + b)(cx + d) by grouping the middle term and the constant term together.
So, the factored form of the trinomial is (2m + 4)(m + 5)

⇒ - 3 = x
⇒ x = -3
Thus, It is not represent an identity.
2) 4x - 3 = 2(2x + 7)
⇒ 4x - 3 = 4x + 14
⇒ - 3 ≠ 14
Thus, It shows no solution.
3) 6x + 3 = 2x + 10
⇒ 6x - 2x = 10 - 3
⇒ 4x = 7
⇒ x = 7/4
Thus, It is not represent an identity.
4) 4(5x + 2) = 20x + 8
⇒ 20x + 8 = 20x + 8
⇒ 20x - 20x = 8 - 8
⇒ 0 = 0
Clearly, '0' is an additive identity.
Thus, This equation shows an identity.
