How To Solve It And How To Calculate The Gst And Pst

Answers

Answer 1

Given:-

Given amount is $50.

Price of article is $24.

GST is 7%.

PST is 7%.

To find:-

The remaining amount.

The GST amount is,

[tex]\begin{gathered} 24\times\frac{7}{100}=0.24\times7 \\ \text{ =1.68} \end{gathered}[/tex]

The PST amount is,

[tex]\begin{gathered} 24\times\frac{7}{100}=0.24\times7 \\ \text{ =1.68} \end{gathered}[/tex]

So the total tax amount is,

[tex]1.68+1.68=3.36[/tex]

Now the total amount of the article is,

[tex]24+3.36=27.36[/tex]

So the remaining amount is,

[tex]50-27.36=22.64[/tex]

So the remaining amount is $22.64

Say a certain manufacturing industry has 63.1 thousand jobs in 2008, but is expected to decline at arate of 1.7 thousand jobs per year from 2008 to 2018. Assuming this holds true, what will be this induchange from 2008 to 2018?a. 70%b. -27%C. -17%d. -75%

Answers

The inicial number of jobs is 63.1 thousand, and each year this number will decrease by 1.7 thousand.

So the change from 2008 to 2018, that is, 10 years, will be:

[tex]10\cdot(-1.7)=-17[/tex]

To find the change in percentage, we need to divide the change (-17) by the inicial amount of jobs (63.1), then we have that:

[tex]\frac{-17}{63.1}=-0.27=-27\text{\%}[/tex]

So the change in this period is -27%, therefore the answer is B.

Suppose Vanessa can clean her bedroom in 30
minutes. Steven can clean the same room in only
15 minutes. If they work together, how long
will it take them to clean the bedroom ?

Answers

How long will it take them to clean the bedroom? 10 minutes

How to calculate the time of the work done together?

Given:

Vanessa  (A)= 30 minutes

Steven (B) = 15 minutes

The total time taken if both work together is given by,

             [tex]A+B=\frac{AB}{A+B} \\\\=\frac{30*15}{30+15}\\\\=\frac{450}{45}\\\\= 10[/tex]

So, it would take 10 minutes to clean the bedroom, if they work together

What is the time - work concept ?

Time and work is concerned with the amount of time it takes a person or a group of people to complete a task and the effectiveness of the work performed by each of them. The rate of work and the amount of time required are inversely proportional. Time taken = 1 / The rate of work.

What is Trigonometry?

There are basic six ratios in trigonometry that help in establishing a relationship between the ratio of sides of a right triangle with the angle. If θ is the angle in a right-angled triangle, formed between the base and hypotenuse, then

sin θ = Perpendicular/Hypotenuse

cos θ = Base/Hypotenuse

tan θ = Perpendicular/Base

The value of the other three functions: cot, sec, and cosec depend on tan, cos, and sin respectively as given below.

cot θ = 1/tan θ = Base/Perpendicular

sec θ = 1/cos θ = Hypotenuse/Base

cosec θ = 1/sin θ = Hypotenuse/Perpendicular

Given:

cos x/ 1- sin x

Using Trigonometric identities

1-sin²x = cos²x

So, on rationalizing

= (cos x) /(1-sinx) x (1+sinx)/(1+sinx)

= (cos x)  (1+sinx) /(1²-sin²x)

=  (cos x)  (1+sinx) /(1-sin²x)

=  (cos x)(1+sinx)/(cos²x)

= (1+sinx)/(cos x)

=1/ cos x + sin x / cos x

Three horse share five bales of hay equally. Five cows share eight bales of hay equally.

How much hay does each horse and each cow get?
Which animal gets more, a horse of a cow? How much more hay do they get?

Answers

How much hay does each horse and each cow get?

(a)The hay shared by 3 horses =  5 bales

So, the hay shared by 1 horse =  x

Rewriting the statements ,

3 h = 5 b  --(1)

1 h = x    -(2)

By applying cross multiplication method to (1) and (2)

3 (x) = 5

x = 5/3

The hay shared by 1 horse =  5/3

(b)The hay shared by 5 cows =  8 bales

So, the hay shared by 1 cow =  y

Rewriting the statements ,

5 c = 8 b  --(3)

1 c = y    -(4)

By applying cross multiplication method to (3) and (4)

5 (y) = 8

x = 8/5

The hay shared by 1 cow = 8/5

Which animal gets more, a horse of a cow?

Comparing the fractions,

The hay shared by 1 horse =  5/3  = 1.7

The hay shared by 1 cow = 8/5 = 1.6

1.7 > 1.6

So,  a horse gets more than a cow

How much more hay do they get?

Considering the difference of fractions,

Amount of more hay consumed = Hay shared by a horse - hay shared by a cow.

                                                     [tex]=\frac{5}{3} -\frac{8}{5} \\\\=\frac{25-24}{15} \\\\=\frac{1}{15}[/tex]

Answers

To solve this exercise let's make a sketch of the rectangular field first:

The length, width, and diagonal of the rectangular field form a right triangle, to determine the width of the rectangle you can apply the Pythagorean theorem.

This theorem states that the square of the hypotenuse is equal to the sum of the square of the legs of the triangle.

[tex]a^2+b^2=c^2[/tex]

The diagonal is the hypotenuse of the triangle, the length is one of the legs "a" and the width is the other leg "b".

Write the theorem for b:

Answers

Answer

Regular pay = $388

Overtime pay = $87.3

Gross pay = $388 + $87.3

Explanation

During the first week of January, Patricia Morgan worked 46 hours at a rate of $9.70 per hour for regular hours.

For overtime, the pay is 1.5 times the normal rate. That is, 1.5 × $9.70 = $14.55

So, working for 46 hours, that is, 40 hours regular pay rate, and 6 hours overtime pay rate.

Regular pay = 40 × $9.70 = $388

Overtime pay = 6 × $14.55 = $87.3

Gross pay = Regular pay + Overtime pay

= $388 + $87.3

= $475.3

It is a quadratic equation in its general form, where "a" stands for the leading coefficient and "c" for the absolute term of f(x).

The general equation of the quadratic equation if (h, k) is the vertex and (x, y) is a point on the curve is given by  

y = [tex]a(x-h)^{2} + k[/tex] ......eqn 1

In the situation where a must be determined at position (h, k) and (x, y)

In the above question, it is given that,

vertex is (h,k) = (0,3) and the point on the graph is (x,y) = (2,7)

Now we'll put the points in the general equation of the quadratic equation to get the desired equation

y = [tex]a(x-h)^{2} + k[/tex]

y = [tex]a(x-0)^{2}[/tex] + 3 .....eqn 1

Now putting the value of (x,y)

7 = [tex]a(2-0)^{2}[/tex] + 3

7 = 4a + 3

4a = 4

a = 1

putting the value of a in the equation 1, we get

y = [tex]x^{2}[/tex] + 3

[tex]x^{2}[/tex] -y +3 = 0

[tex]\begin{gathered} 4x+4y=31 \\ 4x+4(12.25-2x)=31 \\ 4x+49-8x=31 \\ 49-31=8x-4x \\ 18=4x \\ x=\frac{18}{4} \\ x=4.5 \end{gathered}[/tex]

Finding y:

[tex]\begin{gathered} y=12.25-2x \\ y=12.25-2(4.5) \\ y=3.25 \end{gathered}[/tex]

Thus,

Answer:

Each order of Soup = $4.50

Each order of Stew = $3.25

Assume the random variable X is normally distributed with mean μ = 50 and standard deviation o=7. Find the 78th percentile

Answers

The 78th Percentile is 55.402

What is Percentile?

A Percentile (or centile) is a statistic measure that indicates the value below which a given percentage of observations in a group fall. The 20th percentile, for example, is the value (or score) below which 20% of the observations can be found.

The terms Percentile and Percentile rank are frequently used in the reporting of norm-referenced test scores. For example, a score in the 86th percentile, where 86 is the percentile rank, corresponds to a value below which 86% of the observations can be found. In contrast, a score in the 86th percentile indicates that it is at or below the value at which 86% of the observations can be found.

We know that,

μ = 50,

and σ = 7,

First, we need to find the z-score associated to this percentile.

We need to find the value [tex]Z_{p}[/tex] that solves the equation below.

[tex]Pr(Z < Z_{p}) = 0.78[/tex]

The value of [tex]Z_{p}[/tex] that solves the equation above cannot be made directly, it is solved either by looking at a standard normal distribution table or by approximation.

Based on this, we find that that the solution is [tex]Z_{p}[/tex] 0.772, because from the normal table we see that

Pr(Z<0.772)=0.78

Therefore, the percentile we are looking for is computed using the following formula:

[tex]P_{78}[/tex] = μ+ [tex]Z_{p}[/tex] × σ

= 50+0.772×7

= 55.405

Therefore, it is concluded that the corresponding 78-th percentile is found to be [tex]P_{78}[/tex] is 55.405.

Solve the radical equation. Be sure to check all solutions to eliminate extraneous solutions. 7t+5−−−−−√=7 Enter the exact answers.

Answers

The given equation is

[tex]\sqrt[]{7t+5}=7[/tex]

Square both sides to cancel the square root

[tex]\begin{gathered} (\sqrt[]{7t+5})^2=(7)^2 \\ 7t+5=49 \end{gathered}[/tex]

Subtract 5 from both sides

[tex]\begin{gathered} 7t+5-5=49-5 \\ 7t=44 \end{gathered}[/tex]

Divide both sides by 7

[tex]\begin{gathered} \frac{7t}{7}=\frac{44}{7} \\ t=\frac{44}{7} \\ t=6\frac{2}{7} \end{gathered}[/tex]

The solution is t = 44/7 OR t = 6 2/7 (mixed number)
