The equation to calculate the balance in the account after "x" months would be: y = 100 + 25x

And after 6 months, Alexa would have $250 in his retirement account, and after 12 months, he would have $400 in his account.

Step-by-step explanation:

Let's call the balance in Alexa's retirement account after "x" months "y".

The equation to calculate the balance in the account after "x" months would be:

y = 100 + 25x

After 6 months, Alexa would have added 6 * $25 = $150 to the original balance of $100, so the balance would be:

y = 100 + 25 * 6 = 100 + 150 = $250

After 12 months, Alexa would have added 12 * $25 = $300 to the original balance of $100, so the balance would be:

y = 100 + 25 * 12 = 100 + 300 = $400

So, after 6 months, Alexa would have $250 in his retirement account, and after 12 months, he would have $400 in his account.

The value of m∠C in  the triangle  is 42.77°

The sine rule is a mathematical formula used in trigonometry to find the length of a side or the size of an angle in a triangle when two sides and one of the angles opposite to those sides are known. It states that:

a/sin A = b/sin B = c/sin C

Where a, b, and c are the lengths of the sides of the triangle and A, B, and C are the angles opposite to those sides.

m∠A = 47°, a = 28, c = 26.

a/sin A = c/sin C

28/sin 47° = 26/sin C

sin C = (26 sin 47°)/28

sin C = 0.6791

C = arcsin(0.6791)

C = 42.77°

Thus, m∠C = 42.77°

The balance account is prepared in accordance with the provided statement, and both the liabilities and assets total 2800000.

A balance sheet provides you with a quick overview of ones company's financial standing at any particular moment. A balance sheet, along with a revenue statement as well as a cash-flow statement, can aid business leaders in assessing the financial health of their organisation.

Computation of Current assets and Current Liabilities

Current Ratio  (CR) = Current Assets (CA)/ Current Liabilities (CL)  = 2.5

So, CA= 2.5 CL

Current Assets (C.A) - Current Liabilities (C.L) now equals Rs. 60000 as working capital.

Therefore, CA - CL = 60000 0

     2.5 CL-CL = 600000

     1.5 CL = 600000

        CL = 600000/1.5

     C.L = Rs.40000 0

C.A. now equals 2.5 x 400000, or Rs. 1000,000.

Computation of stock

Liquid ratio   = Liquid  assets/Current  liabilities

Or, 1.5 = (Current Assets - Stock )/400000

Or, 1.5  = (10,00, 000 - Stock)/4,00,000

1.5 *400000 = 1000000-Stock

600000 = 1000000- Stock

Therefore, stock = 100000-600000 = 400000

Computation of Proprietary fund; Fixed assets; Capital and Sundry payables (creditors)

Proprietors Fund divided by Permanent Assets equals Proprietors Fund.

Permanent assets therefore equal 0.75 proprietary fund, and

Net working capital  =  0.25 Proprietary fund

Therefore Proprietary fund = 600000/0.25

Proprietary fund = 24,00,0000 and  Fixed assets = 0.75 proprietary fund

= 0.75 of  24,00,000

Therefore, Fixed Assets = 18,00,000

Equity Capital = Proprietary fund - Reserves & Surplus

Therefore, Equity Capital = 2400000-400000

Equity Capital = 20,00,000

Variable payables (creditors) = (Current liabilities - Bank overdraft)

= (400000 - 100000) = 300000

Sundry payables = 300000

Net Current Assets =  (Current Assets - Stock) = 1000000-400000 = 600000

For b to be  in the plane spanned by a1 and a2, h= -17 .

What is plane?

In two dimensions, a plane can continue on forever. The lack of breadth. A plane is an example of coordinate geometry. A point's location in a plane is determined by its coordinates.

A plane is a two-dimensional, flat surface that never ends in mathematics. A plane is a two-dimensional equivalent of a three-dimensional equivalent that contains three spatial dimensions, a line, and a point. Planes can resemble subspaces in some higher-dimensional situations, as if the room's walls had been substantially stretched. These walls have their own existence, exactly as in the context of Euclidean geometry.

A flat surface in three dimensions can be represented using the plane equation. There are several approaches for determining the equation for a given function.. The equation for the plane can be expressed in either cartesian form or vector form.

Hence, the general form of the equation is A(x−x1)+B(y−y1)+C(z−z1)=0

Now,

y is a linear combination of a1 and a2 if it is in the plane, For the plane spanned by a1 and a2,

y = a a1 + b a2, a and b are constants here

[4,1,h] = a[1,4,-2] + b[-2,-3,7]

[4,1,h] = [a - 2b,4a -3b,-2a+ 7b] Vectors are equal if their components are equal by the rules of vector addition and multiplication.

4 = a - 2b

1 = 4a - 3b

h = -2a + 7b

solve for a and b from the two equations for h:

a = -2

b = -3

h = -17

We see that -2[1,4,-2] - 3[-2,-3,7] = [4,1,-17].

we can see that Rule 2 has a higher probability of accepting a shipment containing 20% defectives. Therefore, Rule 2 has a smaller probability of accepting a shipment containing 20% defectives.

To compare the probabilities of acceptance of a shipment containing 20% defectives for the two rules, we can calculate the probabilities for both rules and compare the results.

For Rule 1, the probability of accepting a shipment containing 20% defectives is given by the probability of having 0 defectives in a sample of 10 components. This can be calculated as

P(Accept | 20% defectives) = (0.8)¹⁰

= 0.107374

For Rule 2, the probability of accepting a shipment containing 20% defectives is given by the probability of having 0 or 1 defectives in a sample of 20 components. This can be calculated as:

P(Accept | 20% defectives) = (0.8)²⁰ + ²⁰C₁ * (0.8)¹⁹ * (0.2)

= 0.276

Comparing the two probabilities, we can see that Rule 2 has a higher probability of accepting a shipment containing 20% defectives. Therefore, Rule 2 has a smaller probability of accepting a shipment containing 20% defectives.

Step-by-step explanation:

For me in class there were 6 parts to this problem and this problem is the same in my class so I will add all the answers

So for how many grams of 25% syrup it will be 120-x because the some amount + x = 120 grams of 15% syrup

so 120-x = the some amount of syrup.

This will be the answer for the problem you were asking for

If you have 6 parts keep scrolling since I will supply some more answers

Next part: How much pure sugar is in the 25% syrup?

For the amount of pure sugar there is in the 25% syrup

that will equal 0.25(120-x) = 30-0.25x

Next: How much sugar is in 120 grams of 15% sugar syrup?

10% of 120 is 12

5% = 12/2 = 6

12+6 = 18

Now the earlier stuff from the problem will come in handy

use the previous answers to write an equation

0.25(120-x)+0.10x=18

= 30-0.25x+0.10x=18

30 -0.15x=18

Now the final part to solve the equation and find the 10% solution and the 25% solution

-0.15x=18-30 = -12

-0.15x=-12

x= -12/-0.15

x=80

the problems not done yet though

we need to find the 25% solution

25% solution = 120-x and x = 80

120-80 = 40

The 10% solution is 80 grams and the 25% solution is 40 grams

Answer: Let's call the number of pages printed "x". After printing x pages, the total cost for the Hewlett-Packard printer will be:

$200 + $0.03 * x

And the total cost for the Brother printer will be:

We want to find the number of pages "x" such that the cost of the two printers is the same, i.e., when:

$200 + $0.03 * x = $240 + $0.01 * x

We can isolate x by subtracting $240 from both sides and subtracting $0.01 * x from both sides:

$200 - $240 + $0.03 * x - $0.01 * x = 0

$-40 + $0.02 * x = 0

$0.02 * x = 40

x = 2000

So, the number of pages that need to be printed for the cost of the two printers to be the same is 2000 pages.

∠ B = 23°

Step-by-step explanation:

vertical angles are congruent , then

∠ B = ∠ A , that is

5x - 17 = x + 15 ( subtract x from both sides )

4x - 17 = 15 ( add 17 to both sides )

4x = 32 ( divide both sides by 4 )

x = 8

Then

∠ B = 5x - 17 = 5(8) - 17 = 40 - 17 = 23°

The area of the shaded portion of the given figure is 84 sq. units.

What is meant by area?

The size of a region on a surface is determined by its area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a structure or planar lamina.

From the figure, we can conclude that,

Area of the shaded portion = Area of the square - Area of the four congruent parallelograms.

Now we have to find the area of square and parallelograms separately.

Area of square

Side length l = 12

Area = l *l = 12 * 12 = 144 sq. units

Area of parallelograms

Base b = 5

Height h = 3

Area of 1 parallelogram = b.h = 5 * 3 = 15 sq. units

Since all the parallelograms are congruent,

Area of all 4 parallelograms = 15 * 4 = 60 sq. units

Hence the area of the shaded portion of the given figure = 144 - 60

                                                                                          = 84 sq. units
