8x10^24 divided by 2x10^18

Answer:

  36.4%

Step-by-step explanation:

You want the percentage change from $22 to $30.

The percentage change is given by the formula ...

  percent change = ((new value)/(old value) -1) × 100%

  = (30/22 -1)(100%) ≈ 36.4%

The stock increased in value by about 36.4%.

Answer:

Step-by-step explanation:

4x² + 20x + 25 = (2x)² + 2* 2x *5 + 5²

{Compare with a² + 2ab + b² = (a+ b)²}

                         = (2x + 5)²

                         = (2x +5)*(2x+5)

Side of the square = 2x+ 5

Answer:

Part A is (2x+5)^2. Part B is  (2x+3y)(2x-3y).

Step-by-step explanation:

Part A: The polynomial is prime. When you split the middle term, it becomes 4x^2+10x+10x+25. Then rewrite using the common factor from the two pairs. 2x(2x+5)+5(2x+5). Rewrite in factored form, which is (2x+5)(2x+5). Then combine which is, (2x+5)^2. The length of each side is (2x+5)^2.

Part B: The polynomial is prime. Rewrite 4x^2 as (2x)^2 and 9y^2 as (3y)^2, which looks like (2x)^2-(3y)^2. Both terms are perfect squares. The answer is (2x+3y)(2x-3y).

If demand or annual usage increases by 10 percent, the Economic Order Quantity (EOQ) will increase. The EOQ model is used in inventory management to determine the optimal order quantity that minimizes total inventory costs.

The Economic Order Quantity (EOQ) is a model used in inventory management to determine the optimal order quantity that minimizes total inventory costs. It takes into account factors such as demand, holding costs, and ordering costs. When demand or annual usage increases by 10 percent, it means that more units are being consumed or sold within a given time period.

With an increase in demand, the EOQ will also increase. This is because the EOQ formula takes into consideration the trade-off between holding costs and ordering costs. Holding costs are the costs associated with holding inventory, such as warehousing and insurance, while ordering costs are the costs incurred when placing an order, such as administrative and transportation costs.

When demand increases, more units need to be ordered to meet the higher demand. This results in an increase in ordering costs, as more frequent orders will need to be placed. Consequently, the EOQ will increase to find the new optimal order quantity that balances the increased ordering costs with the holding costs.

In summary, if demand or annual usage increases by 10 percent, the EOQ will increase due to the need to order more frequently to meet the higher demand, resulting in increased ordering costs. This adjustment ensures that the inventory management system remains efficient and cost-effective.

Answer:

x = - \(\frac{14}{3}\)

Step-by-step explanation:

Given

\(\frac{3}{4}\) (x + 5 \(\frac{1}{2}\) ) = \(\frac{5}{8}\)

Multiply both sides by 8 to clear the fractions

6(x + 5 \(\frac{1}{2}\) ) = 5 ← distribute parenthesis on left side

6x + 33 = 5 ( subtract 33 from both sides )

6x = - 28 ( divide both sides by 6 )

x = \(\frac{-28}{6}\) = - \(\frac{14}{3}\)

Answer: I don’t know how to really read that term but the coefficient in ANY term will be the number directly behind a variable. For example, 2x, the variable is ‘x’ and the coefficient is 2. But in the case 2 (space in between) x , 2 is not a coefficient of x. It’ll be 1 because if a variable is by its self, ‘x’, there is always an invisible 1 because the variable is by itself meaning there is only one. You don’t need to put a 1 behind ‘x’ because it should be known already. The coefficient basically tells you how many unknown values there are and the variable tells you the unknown value (when you eventually solve for it).

Using this information try to find the coefficient for that term or rewrite the term correctly.

Answer:

18 hours

Step-by-step explanation:

Let the volume of the pool be x. Since pipe A filled the  pool in 6 hours, the rate of pipe A = x / 6.

Let the rate of pipe b be y, Hose A filled the pool alone for the first 2 hours, this means that the volume filled in the 2 hours is x/6(2 hours) and the two hoses, working together, then finished filling the pool in another 3 hours for the 3 hours the volume filled is x/6(3) + y(3).  hence the total time is:

x/6(2) + x/6(3) + y(3) = x

x/3 + x/2 + 3y = x

Multiply through by 6:

2x + 3x + 18y = 6x

5x + 18y = 6x

18y = x

y = x/18

The rate of pipe B is x/18, this means it would take pipe B 18 hours to full the pool alone

The graph represents g(x) is B) On a coordinate plane, an exponential function decreases from quadrant 2 into quadrant 1 and approaches y = 0.

Consider the function:

\(y = a(1\pm r)^m\)

where m is the number of times this growth/decay occurs, a = initial amount, and r = fraction by which this growth/decay occurs.

If there is negative sign, then there is exponential decay happening by r fraction or 100r %

Given:

Two triangles are congruent, i.e., \(\Delta ABC\cong \Delta XYZ\).

To find:

All the measures of both triangle.

Solution:

We have,

\(\Delta ABC\cong \Delta XYZ\).

We know that, corresponding parts of congruent triangles are congruent (CPCTC).

\(\angle A=\angle X\)

\(\angle B=\angle Y=90^\circ\)

\(\angle C=\angle Z=37^\circ\)

It triangle ABC,

\(\angle A+\angle B+\angle C=180^\circ\)     (Angle sum property)

\(\angle A+90^\circ+37^\circ=180^\circ\)

\(\angle A+127^\circ=180^\circ\)

\(\angle A=180^\circ -127^\circ\)

\(\angle A=53^\circ\)

So,

\(\angle A=\angle C=53^\circ\)

\(AB=XY=3\text{ units}\)

\(BC=YZ=4\text{ units}\)

The given two planes 2x + 4y + 3z = 5 and x + 8y + 10z = 3 are perpendicular to each other.

According to the given question.

We have two planes

2x - 4y + 3z = 5

and,

x + 8y + 10z = 3

Since, two planes are perpenicular if

\(a_{1} a_{2} + b_{1} b_{2} + c_{1} c_{2} = 0\)

Where \(a_{1}\), \(b_{1}\) and \(c_{1}\) and \(a_{2}\), \(b_{2}\) and \(c_{2}\) are the direction ratios of planes.

And the two planes are parallel to each other if

\(\frac{a_{1} }{a_{2} } =\frac{b_{1} }{b_{2} } = \frac{c_{1} }{c_{2} }\)

Here, the direction ratios of plane 2x + 4y + 3z = 5 are 2, -4, and 3  and the direction ratios of plane x + 8y + 10z = 3 are 1, 8, and 10

Now,

2(1) + (-4)(8) + 3(10)

= 2 - 32 + 30

= 0

Since, the sum of the product of the direction ratios of  the two palnes is 0. Therefore, the given two planes 2x + 4y + 3z = 5 and x + 8y + 10z = 3 are perpendicular to each other.
