Answer:

[tex]\boxed{Selling\ Price = Rs.\ 424}[/tex]

Step-by-step explanation:

Cost Price = Rs. 400

Profit = 4 % of Cost Price

=> [tex]\frac{4}{100} * 600[/tex]

=> 4 * 6

=> Profit = Rs. 24

Now, Selling Price = Cost Price + Profit

Selling Price = 400+24

Selling Price = Rs. 424

Answer:

Selling price = ₹ 416

Step-by-step explanation:

Cost Price = ₹ 400

Profit% = 4 %

Profit  =  4 % of  cost price

          = [tex]\frac{4}{100}*400\\\\[/tex]

          = 4 * 4

          = ₹ 16

Selling price = Cost price + profit

                    = 400 + 16

                    = ₹ 416

Answer:

26.25 cm²

Step-by-step explanation:

The area of the shaded part is the area of the shaded triangle subtract the area of the white triangle.

Since the triangles are similar then the ratios of corresponding sides are equal.

let the height of the white triangle be h, then

[tex]\frac{12}{9}[/tex] = [tex]\frac{10}{h}[/tex] ( cross- multiply )

12h = 90 ( divide both sides by 12 )

h = 7.5

shaded area = [tex]\frac{1}{2}[/tex] × 12 × 10 - [tex]\frac{1}{2}[/tex] × 9 × 7.5 = 60 - 33.75 = 26.25 cm²

Answer:

17,725/14.

Step-by-step explanation:

Let's say that the blank is represented by x.

Since the question asks what is 16.8% of x, we can set up a proportion where 16.8 out of 100 is equivalent to 212.7 out of x. The 100 represents the "whole" number, which corresponds to x. The 212.7 IS the 16.8 of x.

[tex]\frac{16.8}{100} =\frac{212.7}{x}[/tex]

16.8 * x = 212.7 * 100

16.8x = 21,270

x = 21,270 / 16.8

x = 212,700 / 168

x = 17,725 / 14 = 1,266.071429

To check our work, 1,266.071429 * 0.168 = 212.7.

Hope this helps!

Answer:

[tex]P(Brown\ or\ Green) = \frac{13}{25}[/tex]

Step-by-step explanation:

Given

[tex]n(Brown) = 20[/tex]

[tex]n(Green) = 6[/tex]

[tex]n(Blue) = 17[/tex]

[tex]n(Hazel) = 7[/tex]

Required

Determine the probability of Brown or Green eyes

First, the total number of respondents have to be calculated;

[tex]Total = 20 + 6 + 7 + 17[/tex]

[tex]Total = 50[/tex]

The events described above is a mutually exclusive event and as such, the required probability will be calculated by;

[tex]P(Brown\ or\ Green) = P(Brown) + P(Green)[/tex]

Calculating P(Brown)

[tex]P(Brown) = \frac{n(Brown)}{Total}[/tex]

Substitute 20 for n(Brown) and 50 for Total

[tex]P(Brown) = \frac{20}{50}[/tex]

Calculating P(Green)

[tex]P(Green) = \frac{n(Green)}{Total}[/tex]

Substitute 6 for n(Green) and 50 for Total

[tex]P(Green) = \frac{6}{50}[/tex]

So;

[tex]P(Brown\ or\ Green) = P(Brown) + P(Green)[/tex]

[tex]P(Brown\ or\ Green) = \frac{20}{50} + \frac{6}{20}[/tex]

Take LCM

[tex]P(Brown\ or\ Green) = \frac{20+6}{50}[/tex]

[tex]P(Brown\ or\ Green) = \frac{26}{50}[/tex]

Divide the numerator and denominator by 2

[tex]P(Brown\ or\ Green) = \frac{13}{25}[/tex]

Answer:

13/25

Step-by-step explanation:

Total number of people = 50

Probability of choosing a person with brown eyes [P(A)] = 20/50

Probability of choosing a person with green eyes [P(B)] = 6/50

Using the addition rule of mutual exclusive events (since they have specified brown OR blue, we use this formula):

P(A U B) = P(A) + P(B)

=> P(A U B) = 20/50 + 6/50 = 26/50 = 13/25

Therefore the probability of a person choosing a group that has brown or green eyes = 13/25

Also I got it right on edge haha, if you're still worried!!!!!!!!

Answer:

The market price of the article is Rs. 978.72

Step-by-step explanation:

Let x represents the market price.

Let y represents the selling price.

Let z represents the cost price.

if an article is sold with 20% discount then there will be a profit of 15%.

SP = CP+Profit =z+0.15z=1.15z

ATQ

[tex]0.80x = 1.15z\\0.80x- 1.15z = 0[/tex]

If it is sold at 10% discount then there will be a profit of Rs.200

ATQ

[tex]0.9x - z = 200[/tex]

Now we are supposed to find the market price of an article.

[tex]0.9x - z= 200[/tex]

Multiplying 1.15 both sides

[tex]0.9x \times 1.15 - 1.15z = 200 \times 1.15\\1.035x - 1.15z = 230[/tex]

We know that[tex]1.15z = 0.80x[/tex]

[tex]1.035x - 0.80z = 230\\0.235x = 230\\x = \frac{230}{0.235}\\x= Rs. 978.72[/tex]

Hence The market price of the article is Rs. 978.72

Answer:

$1280000

Step-by-step explanation:

Given that :

John has a life insurance policy that will pay his family $32,000 per year if he dies

If interest rates are at 2.5% when the insurance company has to pay

The amount of the lump sum that the insurance company must out into a bank account can be determined by the division of the amount to be paid by the interest rate.

i.e

the amount of the lump sum = $32000/2.5%

the amount of the lump sum = $32000/0.025

the amount of the lump sum = $1280000

Answer:

the trig function you would use to find x would be cosine becuase its adjacent/ hypotenuse.

solving it would give you 49 becuase its cosine(x)=13/20 and you have to multiply by the inverse of cosine

to solve for y you would use sine of y which would be opposite/ hypotenuse = 13/20

Answer:

There is no solution.

Rewrite -2x + y = -6 so it starts with y =...

y = 2x - 6

Substitute that in 2/3x - 1/3y = -2 gives:

2/3x - 1/3*(2x -6) = -2

2/3x - 2/3x + 2 = -2

0 + 2 = -2

This statement is not true, and that means there is no solution.

Answer:

18

Step-by-step explanation:

Let's say x is Oscar's age, and y is Vanessa's age.

When Oscar was Vanessa's age, Vanessa was y−(x−y) = 2y−x years old.  Oscar is five times older than this:

x = 5 (2y − x)

x = 10y − 5x

6x = 10y

3x = 5y

When Vanessa is Oscar's age, Oscar will be x+(x−y) = 2x−y years old.  The sum of their ages will by 72.

2x−y + x = 72

3x − y = 72

Substituting:

5y − y = 72

4y = 72

y = 18

Vanessa is 18.  Which means Oscar is 30.

Let's check our answer.  When Oscar was 18, Vanessa was 6.  Oscar is 5 times older than that (30).  When Vanessa is 30, Oscar will be 42, and their ages will add up to 72.

Answer:

1) Factor form : [tex]h(t)=-5t(t-8)[/tex]

2) 8 second after launch.

Step-by-step explanation:

The height of the ball (in meters above the ground) t seconds after launch is modeled by

[tex]h(t)=-5t^2+40t[/tex]

To find the time when ball hit the ground, we need to find the factor form of the given function.

[tex]h(t)=-5t(t-8)[/tex]

When ball hi the ground, then height of the ball from the ground is 0.

[tex]h(t)=0[/tex]

[tex]-5t(t-8)=0[/tex]

Using zero product property, we get

[tex]-5t=0\Rightarrow t=0[/tex]

[tex]t-8=0\Rightarrow t=8[/tex]

Ball hit the ground at t=0 and t=8. It means ball hit the ground in starting and 8 second after launch.

Answer:

-5t(t - 8) and it hit 8 seconds after launch.

Step-by-step explanation:

First let's solve for the value in the parentheses.

[tex]0.35 \cdot 100 = 35[/tex]

We know this is correct because if we multiply a value by 100, the decimal point is moved 2 places to the left.

35 - 35 = 0, so the value of this expression equals out to be 0.

Answer:

moves it up 6 units

Step-by-step explanation:

y = f(x) + C C > 0 moves it up

f(x) = f(x) + 6 moves it up 6 units

Answer:

Vertical shift, 6 up.

Step-by-step explanation:

The entire function f(x) has a value of six added to it. That means that regardless of where f(x) was plotted on the coordinate plane, after the translation f(x) + 6, every single point would increase its value by six. Since all points would increase their values by six, the entire function would shift 6 up.

Answer:

140°

Step-by-step explanation:

Every triangles angles when combined equals 180°

In an isosceles triangle there are 2 acute angles and one obtuse angles.

It was given that the base angle/acute angle is 20°

This brings us to our equation. 20° + 20° + x = 180°

20 + 20 = 40

40 + x = 180

Now we solve algebraically:

180-40= 140

Therefore the answer is x = 140°

Answer:

x = 73

Step-by-step explanation:

The measure of the sum of the arcs in a circle = 360°.

Sum the given arc measures and equate to 360, that is

95 + 52 + 67 + 2x = 360

214 + 2x = 360 ( subtract 214 from both sides )

2x = 146 ( divide both sides by 2 )

x = 73

Answer:

The correct answer is C. ​Sample, because the collection of temperatures for four state capitals is a subset of all state capitals.

Step-by-step explanation:

we cannot fully understand this answer without first defining the parameters that are involved in the questions, the two key terms are; Population or sample.

Population: a population contains all the set of data which is in consideration and

Sample: Sample is the range of values in an experiment.

The main difference between a population :A population basically includes all  the elements from a set of data while  a sample only consists of  one or more observations drawn from the population.

we can say safely that a sample is a subset of a population.

Since we it have been stated that the temperatures of from four states capitals out of 50 states then our explanation supports our answer.

Answer:

288 in²

Step-by-step explanation:

The formula used to solve this question is :

Lateral Surface Area = s( P1 + P2)

Where s = slant height = 2 inches

P1 and P2 = Perimeter of the bases

Perimeter of base 1 = 4 × length of the end of the small square

4 × 17 inches = 68 inches

Perimeter of base 2 = 4 × length of the end of the large square

4 × 19 inches = 76 inches

Lateral Surface Area = 2 × (68 + 76)

= 2 × 144

= 288 in²
