The length of a rectangle is 5m longer than its width. If the perimeter of the rectangle is 54m, find its length and width.

Answers

Answer:

Width=11

Length=16

Step-by-step explanation:

P=2L+2W

54=2(5+w)+2w

Open the brackets

10+2w+2w=54

10+4w=54

Collect the like terms

4w=54-10

4w/4w=44/4

W=11

Since the length is 5m longer

Therefore:11+5=16

Width=11

Length=16

A TV and Washing machine were purchased for Rs 15000 each. If together, they are sold at Rs 35000, What is Profit and Profit%

Answers

Given:

A TV and Washing machine were purchased for Rs 15000 each.

Together, they are sold at Rs 35000.

To find:

The profit and profit%.

Solution:

A TV and Washing machine were purchased for Rs 15000 each. So, the total cost price is

[tex]C.P.=15000+15000[/tex]

[tex]C.P.=30000[/tex]

Together, they are sold at Rs 35000. So, the selling price S.P. is 35000.

Now,

[tex]Profit=S.P.-C.P.[/tex]

[tex]Profit=35000-30000[/tex]

[tex]Profit=5000[/tex]

And,

[tex]Profit\%=\dfrac{Profit}{C.P.}\times 100[/tex]

[tex]Profit\%=\dfrac{5000}{30000}\times 100[/tex]

[tex]Profit\%=\dfrac{50}{3}[/tex]

[tex]Profit\%\approx 16.67[/tex]

Therefore, the profit is Rs. 5000 and the profit percent is 16.67%.

The water level in a harbor is described by the function y = 7 cosine (pi x/6) + 25, where y represents the water level measured in feet, and x represents the number of hours since high tide. After approximately how many hours is the water expected to reach a depth of 28 feet the second time? Round to the nearest hour.

1 hour
2 hours
10 hours
12 hours

Answers

Answer:

10 hours

Step-by-step explanation:

The total number of hours the water is expected to reach a depth of 28 feet the second time is 2 hours and this can be determined by using the given data.

Given :

Function  ---  [tex]\rm y = 7cos\dfrac{\pi x}{6}+25[/tex]Where y represents the water level measured in feet, and x represents the number of hours since high tide.

Substitute the value of y = 28 in the given function in order to determine the total number of hours water expected to reach a depth of 28 feet the second time.

[tex]\rm 28 = 7cos\dfrac{\pi x}{6}+25[/tex]

Subtract 25 on both sides in the above function.

[tex]\rm 3= 7cos\dfrac{\pi x}{6}[/tex]

Divide on both sides by 7 in the above expression.

[tex]\rm \dfrac{3}{7}= cos\dfrac{\pi x}{6}[/tex]

Further, simplify the above expression.

[tex]\rm 64.62= \dfrac{\pi x}{6}[/tex]

Cross multiply in the above expression.

[tex]\rm x = \dfrac{64.62\times 6 }{\pi}[/tex]

To convert into radian multiply the above expression by [tex]\pi/180[/tex].

[tex]\rm x = \dfrac{64.62\times 6 }{\pi}\times \dfrac{\pi}{180}[/tex]

x = 2.42 hours

x [tex]\approx[/tex] 2 hours (round off to the nearest hour)

Step-by-step explanation:

You need to find how much each side of the table is changing each time and change that into a fraction. In this example, the change in time is .5 hours. Repeat with the other side to get 12.5 miles. Next you change it into a fraction with the distance over the time to get 12.5/.5. Type this into the calculator to get the answer which is 15 mph.

The base of a regular pyramid is a hexagon.

What is the area of the base of the pyramid?
Enter your answer in the box. Express your answer in radical form.

Answers

Answer:

Step-by-step explanation:

For the single triangle

sin60=h/14, h=14sin60

cos60=b/(2(14)), b/2=14cos60 so the total area is nhb/2 where n is the number of sides

A=n(14sin60)(14cos60), since n=6

A=6(14sin60)(14cos60)

A=114.75cm^2

The hexagon is divided into 6 equal triangles. Then the area of the base of the pyramid is 509 square cm.

What is Geometry?

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The base of a regular pyramid is a hexagon.

The hexagon is divided into 6 equal triangles. Then the height of the triangle will be

[tex]\rm a = 14 \sin 60^o\\\\a = 12.12[/tex]

Then the area of the triangle will be

[tex]\rm Area \ of \ triangle = 0.5 \times 14 \times 12.12\\\\Area \ of \ triangle = 84.84 \ cm^2[/tex]

Then the area of the base of the pyramid will be

[tex]\rm Area \ of \ base \ pyramid = 6 \times Area \ of \ triangle\\\\Area \ of \ base \ pyramid = 6 \times 84.84\\\\Area \ of \ base \ pyramid = 509.04 \approx 509 \ \ cm^2[/tex]

so all of the angles added together will equal 180 and if angle qrt and angle srt are congruent then they are equal to each so first we subtract 76 from 180 and get 104. then we divide it by 2 because the two missing angles are congruent. 104/2=52 so h and j =52

An hour before show time, only 105 people have arrived to the concert. According to the statistics, 95% of the people have yet to arrive. How many tickets were sold for the concert?

Answers

Answer: 2,100 tickets

Step-by-step explanation:

105 people have arrived for the concert yet it is said that 95% of people are yet to arrive. This means that the 105 people are 5% of the tickets sold.

Assume the total number of tickets sold is x:

5% * x = 105

0.05x = 105

x = 105 / 0.05

x = 2,100 tickets

Answer:

2100

Step-by-step explanation:

x= 2,100

5% x = 105

0.05x = 105

x = 105/0.05
