Which value is a solution to the inequality x 4

The box of pancake says that it makes 10 pancakes but sam is able to make 8 pancakes from the ingredient. Here the number 10 represents Theoretical yield.

Here,

Theoretical yield can be defined as the product received from the  complete conversion of the limiting reactant in a chemical process.

It is the amount of product resulting from a theoretical chemical reaction and it is not the same as the amount you'll actually get from a reaction in the lab.

Theoretical yield is commonly expressed in terms of grams or moles.  the actual yield is the amount of product actually produced by a reaction. Actual yield is usually a smaller quantity because few chemical reactions proceed with 100% efficiency because of loss recovering the product and because other reactions may be occurring that reduce the product.  so 10 here is a theoretical yield bot the actual yield.

Total amount of money in the account will be $456.

Simple interest is an interest charge that borrowers pay lenders for a loan. It is calculated using the principal only and does not include compounding interest.

The formula for simple interest is: Simple Interest = Principal × Rate × Time

Principal (P) is $300

Rate (R) is 6.5%

Time (T) is 8 years.

Simple Interest = $300 × 0.065 × 8

Simple Interest = $156

Total Amount = Principal + Simple Interest

Total Amount = $300 + $156

Total Amount = $456.

The order of convergence of the formula as h approaches 0 is at least 1.

To determine the order of convergence as h approaches 0 for the approximation of f'(z) using the given formula, we need to analyze the behavior of the formula as h becomes smaller.

Let's rewrite the formula in a more structured form for better clarity:

f'(z) ≈ [F(z + 2h) - 8F(z + h) + 8F(z - h) - F(z - 2h)] / (12h)

As h approaches 0, we can rewrite the formula using the limit notation:

f'(z) ≈ lim(h→0) [F(z + 2h) - 8F(z + h) + 8F(z - h) - F(z - 2h)] / (12h)

In this case, we can simplify the limit expression by dividing both the numerator and denominator by h:

f'(z) ≈ lim(h→0) [F(z + 2h)/h - 8F(z + h)/h + 8F(z - h)/h - F(z - 2h)/h] / 12

f'(z) ≈ lim(h→0) [F'(z) - 8F'(z) + 8F'(z) - F'(z)] / 12

f'(z) ≈ lim(h→0) 0 / 12

f'(z) ≈ 0

From this analysis, we see that as h approaches 0, the f'(z) approaches 0. This means that the order of convergence of the given formula is at least 1.

(a) The expected profit of the game is $0. (b) The variance of the profit is 0. (c) The probability of gaining $20 in 10 plays is 0.

To solve the given problem, we'll calculate the expected profit, variance of the profit, and the probability of gaining $20 in 10 game plays.

(a) Expected Profit:

To calculate the expected profit, we need to multiply the potential profit or loss with its corresponding probability and sum them up.

Profit (X) = Gain - Loss = $10 - $10 = $0

Probability of gaining: P(X = $0) = P(Z > 5) = 0 (since Z is only defined up to 5)

Expected Profit (E(X)) = $0 * P(X = $0) = $0

(b) Variance of the Profit:

The variance can be calculated using the formula: Var(X) = E(X^2) - (E(X))^2.

In this case, since the profit is always zero, the variance will also be zero.

Variance of the Profit (Var(X)) = 0 - (0)^2 = 0

(c) Probability of Gaining $20 in 10 plays:

Since each play is independent, the probability of gaining $20 in a single play is 0. Since the probability of gaining is 0 for each play, the probability of gaining $20 in 10 plays will also be 0.

The minimum amount that Mr. Khumalo can be charged for the cash deposit is R99.12.

To calculate the minimum amount charged for a cash deposit over the counter at Standard Bank, we'll use the given information.

The deposit charge includes an initial fee of R10.39, and an additional fee of K1.95 per R100 or part thereof, with a minimum charge of R16.00.

First, we calculate the additional fee based on the deposit amount:

Additional fee = (Deposit amount / 100) x K1.95

For Mr. Khumalo's deposit of R4,550.00:

Additional fee = (4,550.00 / 100) x 1.95

Additional fee = 88.725

Next, we compare the additional fee to the minimum charge of R16.00:

If the additional fee is less than the minimum charge, the minimum charge applies. Otherwise, the additional fee is charged.

Since the additional fee of R88.725 is greater than the minimum charge of R16.00, the additional fee will be charged.

Finally, we add the initial fee and the additional fee to get the total charge:

Total charge = Initial fee + Additional fee

Total charge = R10.39 + R88.725

Total charge = R99.115

Therefore, the minimum amount that Mr. Khumalo can be charged for the cash deposit is R99.12.

Answer:

m∠J is approximately equal to m∠H and m∠I, so it is also approximately 40 degrees.

Step-by-step explanation:

To find the measures of angles H, I, and J, we can use the fact that HI is approximately equal to IJ. Let's denote the measures of angles H, I, and J as m∠H, m∠I, and m∠J, respectively.

Given that HI is approximately equal to IJ, we can say that m∠H is approximately equal to m∠J.

So, m∠H ≈ m∠J.

We're also given that m∠H = 3x + 10 and m∠I = 6x - 20.

Since m∠H ≈ m∠J, we can equate their expressions:

3x + 10 ≈ 6x - 20.

To solve for x, we can subtract 3x from both sides and add 20 to both sides:

10 + 20 ≈ 6x - 3x.

30 ≈ 3x.

Dividing both sides by 3, we find:

10 ≈ x.

Now that we have the value of x, we can substitute it back into the expressions for m∠H and m∠I:

m∠H = 3x + 10 = 3(10) + 10 = 30 + 10 = 40.

m∠I = 6x - 20 = 6(10) - 20 = 60 - 20 = 40.

Therefore, the measures of angles H, I, and J are:

m∠H = 40 degrees,

m∠I = 40 degrees,

m∠J is approximately equal to m∠H and m∠I, so it is also approximately 40 degrees.

The polynomial of degree 3 with zeros at x = 3, x = -4, and x = 5 is P(x) = x^3 - 4x^2 - 17x + 60.  

To construct a polynomial of degree 3 with zeros at x = 3, x = -4, and x = 5, we can use the fact that the polynomial can be written as a product of linear factors corresponding to each zero.

The factor corresponding to x = 3 is (x - 3).

The factor corresponding to x = -4 is (x + 4).

The factor corresponding to x = 5 is (x - 5).

To obtain the polynomial, we multiply these factors together:

P(x) = (x - 3)(x + 4)(x - 5)

Expanding this expression gives us:

Answer:

  4π/3 ≈ 4.18879 cubic units

Step-by-step explanation:

You want the volume of revolution formed by revolving the 1st-quadrant area under y = 0.25 -(x -4)² around the y-axis.

There are several ways to find the volume of revolution. One can integrate a differential of volume, where that differential is a cylindrical shell or a washer. Alternatively, one can multiply the area under the curve by the centerline length of the path of revolution. We choose this latter approach.

The area in the first quadrant of the region being rotated can be found as the integral between its x-intercepts.

The x-intercepts are found by ...

  0 = 1/4 -(x -4)²

  x -4 = ±√(1/4) = ±1/2

  x = 4 ± 1/2 = {3.5, 4.5} . . . . . . x-intercepts

Then the area is ...

  [tex]\displaystyle\int_{3.5}^{4.5}(0.25-(x-4)^2)\,dx=\left[0.25x-\dfrac{1}{3}(x-4)^3\right]_{3.5}^{4.5}\\\\\\=0.25(1)-\dfrac{1}{3}(0.5^3-(-0.5)^3)=\dfrac{1}{6}\qquad\text{square units}[/tex]

The radius from the y-axis to the line of symmetry of the area is 4 units, so the length of the rotation path is

  C = 2πr = 2π(4) = 8π

The product of this path length and the area is ...

  V = C·A = (8π)(1/6) = 4π/3

The volume of the solid is 4π/3 cubic units.

__

Additional comment

The area under a symmetrical portion of a parabola is 2/3 of the area of the enclosing rectangle. The portion of the parabola in the 1st quadrant is 1 unit wide and 0.25 units high, so its area is (1)(1/4)(2/3) = 1/6 square unit, as we found above.

Answer:

3.3 seconds

Step-by-step explanation:

To find the time it takes for the ball to hit the ground, we need to solve the equation y = 0, since the ball will be on the ground when its height (y) is zero.

The equation given is:

y = -16t^2 + 20t + 7

Setting y to zero:

0 = -16t^2 + 20t + 7

To solve this quadratic equation, we can either factor it or use the quadratic formula. In this case, factoring may not be straightforward, so let's use the quadratic formula:

t = (-b ± √(b^2 - 4ac)) / (2a)

For our equation, a = -16, b = 20, and c = 7. Substituting these values into the quadratic formula:

t = (-20 ± √(20^2 - 4(-16)(7))) / (2(-16))

t = (-20 ± √(400 + 448)) / (-32)

t = (-20 ± √848) / (-32)

Simplifying further:

t = (-20 ± √(16 * 53)) / (-32)

t = (-20 ± 4√53) / (-32)

Now we have two possible solutions for t:

t1 = (-20 + 4√53) / (-32)

t2 = (-20 - 4√53) / (-32)

Since time cannot be negative in this context, we can disregard the negative solution.

t ≈ (-20 + 4√53) / (-32)

Calculating this value:

t ≈ 3.3 seconds (rounded to one decimal place)

Therefore, it will take approximately 3.3 seconds for the ball to hit the ground.

The missing angle is 25 degrees.

We are given that;

A polygon with 6 side have interior angles 90, 98, 140, x, 155, 112

Now,

we can write:

S = (6 - 2) × 180 degrees

S = 4 × 180 degrees

S = 720 degrees

We know that the sum of the given interior angles is:

90 + 98 + 140 + x + 155 + 112 = 695 + x

Since the sum of the interior angles of a polygon with 6 sides is equal to 720 degrees, we can write:

695 + x = 720

Solving for x, we get:

x = 25 degrees

Therefore, by the polygon the answer will be 25 degrees.

The height of the given triangle will be 13.416 cm.

Given a right-angle triangle that has a hypotenuse of 14 cm, height of x, and base of 4 cm.

The Pythagorean theorem is a fundamental principle in geometry that establishes a relationship between the sides of a right triangle. It states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

Applying the Pythagorean theorem, we can write:

[tex]14^2 = 4^2 + x^2[/tex]

Simplifying the equation:

[tex]196 = 16 + x^2[/tex]

The marked price of the article is approximately Rs. 833.33, and the cost price is Rs. 500.

Let's assume the marked price of the article is M and the cost price is C.

According to the given information:

When the shopkeeper sells the object at a discount of 25%, he incurs a loss of Rs. 125. This means that the selling price (S) is 25% less than the marked price (M) and it is equal to the cost price (C) minus Rs. 125.

S = C - Rs. 125

S = M - 0.25M

C - Rs. 125 = M - 0.25M

When the shopkeeper sells the object at a discount of 10%, he gains Rs. 250. This means that the selling price (S) is 10% less than the marked price (M) and it is equal to the cost price (C) plus Rs. 250.

S = C + Rs. 250

S = M - 0.10M

C + Rs. 250 = M - 0.10M

Now we can solve these two equations simultaneously to find the marked price (M) and the cost price (C) of the article.

C - Rs. 125 = M - 0.25M --> C = 0.75M - Rs. 125 (Equation 1)

C + Rs. 250 = M - 0.10M --> C = 0.90M - Rs. 250 (Equation 2)

Setting Equation 1 equal to Equation 2:

0.75M - Rs. 125 = 0.90M - Rs. 250

Rearranging the equation:

0.90M - 0.75M = Rs. 250 - Rs. 125

0.15M = Rs. 125

M = Rs. 125 / 0.15

M = Rs. 833.33 (approx.)

Substituting the value of M back into Equation 1 to find C:

C = 0.75M - Rs. 125

C = 0.75 * 833.33 - Rs. 125

C = Rs. 625 - Rs. 125

C = Rs. 500

Therefore, the marked price of the article is approximately Rs. 833.33, and the cost price is Rs. 500.
