The length of a rectangle is 6 yards longer than its width and
If the perimeter of the rectangle is 72 yards, find its length and width.

Answers

Answer 1

Let...

length=x+6

width=x

x+x+x+6+x+6=72

4x+12=72

4x=60

x=15

x+6=21

answer: length=21 and width=15

Answer 2

To solve for the length and width of the rectangle, we first need to understand the formulas and relationships involved:
- The perimeter (P) of a rectangle is the total distance around its boundary, which is calculated by adding together twice the length (L) and twice the width (W): `P = 2L + 2W`.
- We have two pieces of information to work with:
 1. The length is 6 yards longer than the width, which we can express as `L = W + 6`.
 2. The perimeter is 72 yards, so `P = 72`.
With these equations, we can set up our system to solve for the length and width:
1. Substitute the expression for L from the first piece of information into the perimeter formula:
  `P = 2(W + 6) + 2W`
2. Plug in the value for the perimeter:
  `72 = 2(W + 6) + 2W`
3. Distribute the 2 through the parentheses:
  `72 = 2W + 12 + 2W`
4. Combine the W terms:
  `72 = 4W + 12`
5. Isolate the W term by subtracting 12 from each side:
  `72 - 12 = 4W`
  `60 = 4W`
6. Divide by 4 to solve for W:
  `W = 60 / 4`  
  `W = 15`
Now that we have the width, we can use the first equation to solve for the length:
`L = W + 6`
`L = 15 + 6`
`L = 21`
So, the width (W) is 15 yards and the length (L) is 21 yards.

school spirit club wants to raise money by selling t-shirts. one local company charges a fixed fee of $75 for creating the design and $5 for each shirt that they print. Write an equation describing the spirit club's income if they sell each t-shirt for $8

Answers

Answer:

The profit = $(3x - 75) where x = number of t-shirts sold

Step-by-step explanation:

School spirit club wants to raise money by selling t-shirts. one local company charges a fixed fee of $75 for creating the design and $5 for each shirt that they print.

We have to find the club's income if they sell each t-shirt for $8.

Let the number of t-shirts that the club sell be equal to x.

So the cost of making x t-shirts = 75 + 5x

If the club sells x t-shirts , then the money they earn = 8x

Profit = selling price - cost price

          = 8x - (75 + 5x)

          = $(3x - 75)

The club also needs to sell at least 25 t-shirts to make a profit and from then on makes a profit of $3 on each t-shirt they sell.

ABCD is a trapezium in which AB is parallel to DC, bd is a diagonal and E is the mid point of AD a line is drawn through E parallel to AB intersecting BC at F show that F is the mid point of BC​

Answers

Answer:

F is the mid point of BC. (Proved)

Step-by-step explanation:

See the attached diagram.

Given AB ║ CD and EF is drawn to be parallel to AB.

So, EF ║ AB ║ CD .......... (1)

Now, in Δ ABD, E is the midpoint of AD and EG is parallel to AB.

So, G must be the midpoint of BD.

Now, in Δ BCD, G is the midpoint of DB and GF is parallel to CD. {From relation (1)}

So, we can write F is the midpoint of BC. (Proved)

Two cars travel at the same speed to different destinations. Car A reaches its destination in 15 minutes. Car B reaches its destination in 35 minutes. Car B travels 15 miles farther than Car A. How fast do the cars travel? Write your answer as a fraction in simplest form.

Answers

Answer:

The cars are travelling ar the speed 45 mph.

Step-by-step explanation:

Let the two cars are moving at the speed of x mph.

Now, Car A reaches its destination in 15 minutes i.e. [tex]\frac{15}{60} = 0.25[/tex] hours.

Therefore, Car A travels in 15 minutes by 0.25x miles.

Again, Car B reaches its destination in 35 minutes i.e. [tex]\frac{35}{60} = 0.583[/tex] hours.

Therefore, Car B travels in 35 minutes by 0.583x miles.

Given that, (0.583x - 0.25x) = 15

⇒ 0.333x = 15

x = 45 mph

Therefore, the cars are travelling ar the speed 45 mph. (Answer)

Final answer:

The cars travel at a speed of 3/4 miles per minute.

Explanation:

To find the speed of the cars, we can use the formula Speed = Distance/Time. Let's assume that Car A's speed is x miles per minute. Since Car B travels 15 miles farther than Car A and takes 35 minutes to reach its destination, Car B's speed would also be x miles per minute. Now, using the given information, we can set up two equations:

x * 15 = x * 35 - 15

Simplifying the equation, we get:

15x = 35x - 15

20x = 15

x = 0.75

Therefore, the cars travel at a speed of 0.75 miles per minute or the fraction 3/4 miles per minute.

A typical marathon is 26.2 miles. Allan averages 12 kilometers per 1 hour when running in marathons. How long does it take for Allan to complete a marathon, to the nearest tenth of an hour.

Answers

Answer:

3.5 hours

Step-by-step explanation:

Given: Distance= 26.2 miles

           Speed= 12 km/h

First lets convert the unit of speed from kmh to mph.

Remember, 1 mile= 1.609 km

∴ For speed of 12 km/h= [tex]\frac{12}{1.609}= 7.45\ mph[/tex]

Speed= 7.45 mph

Next, find time taken by Allan to complete a Marathon.

[tex]Time= \frac{Distance}{speed}[/tex]

⇒ Time= [tex]\frac{26.2}{7.45}[/tex]

∴ Time= 3.516 hours ≅ 3.5 h (nearest tenth)

Allan took 3.5 hours to complete marathon.

Allan takes approximately 3.5 hours to complete a marathon. This is determined by converting the marathon distance to kilometers and dividing it by his running speed.

To determine how long it takes Allan to complete a marathon, we need to convert the marathon distance from miles to kilometers and then find the time it takes based on his running speed.

1 mile is approximately 1.60934 kilometers, so:

26.2 miles × 1.60934 km/mile ≈ 42.164 km

Allan runs at an average speed of 12 kilometers per hour. The time (t) needed to complete the marathon can be calculated as:

t = distance / speed

t ≈ 42.164 km / 12 km/h ≈ 3.514 hours

Rounding to the nearest tenth of an hour, Allan takes approximately 3.5 hours to complete the marathon.

what is the sum of 7.09 + 13.95​

Answers

Answer:

21.04

Step-by-step explanation:

Start by adding the hundredths category.  0.09 + 0.05 = 0.14,  this means that your hundredths column will be a 4,  and you will carry the 1 over to the tenths.

Now add your tenths.  0.0 + 0.9 + 0.1 = 1.0,  which means that your tenths column is a 0.  Carry the 1 over to the whole numbers.

Now add your whole numbers.  7 + 13 + 1 = 21.  Combine your terms and you get 21.04

Final answer:

21.04

Explanation:

To find the sum of 7.09 and 13.95, we simply add the two numbers together, aligning the decimal points vertically.

Add the hundredths place: 9 (from 7.09) + 5 (from 13.95) = 14. Write down 4 and carry over 1 to the tenths place.Add the tenths place: 0 (from 7.09) + 9 (from 13.95) + 1 (the carryover) = 10. Write down 0 and carry over 1 to the ones place.Add the ones place: 7 (from 7.09) + 3 (from 13.95) + 1 (the carryover) = 11. Hence, write down 1 and carry over another 1 to the tens place.Add the tens place, which is just the carryover: 1 (from the carryover) + 1 (from 13.95) = 2. So, write down 2.

Putting it all together, we get 21.04 as the final sum.

Sunil takes 5 more days than Anil to a certain work . Anil left the work after 4days,Sunil takes 5days to complete the rest work . How many days they took to complete the work​

Answers

Answer:

Anil would take 10 days and Sunil would take 15 days to complete the work.

Step-by-step Explanation:

To Determine:

How many days they took to complete the work?​

Information Fetching and Solution steps:

Sunil takes 5 more days than Anil to a certain workAnil left the work after 4 daysSunil takes 5 days to complete the rest work

Let is consider,

The number of days taken by Anil to complete the required work = d.

The number of days taken by Sunil to complete the required work = d + 5

Work done by Anil in one day = 1÷d

Work done by Sunil in one day = 1÷ (d+5)

Work done together by Anil and Sunil for one day = 1/d + 1/(d+5)

                                                                                    = (d+5+d)/d(d+5)

                                                                                    = (2d+5)/d(d+5)  

Work done together by Anil and Sunil for 4 days = 4×(2d+5)/d(d+5) ....[A]

Work done by Sunil in 5 days = 5÷ (d+5)  ....[B]

By adding equation [A] and [B], we can determine the complete work

[A] + [B] = 1

((4×(2d+5)/d(d+5))) + (5÷ (d+5)) = 1

8d+20+5d=1d(d+5)

13d+20=d²+5d

−d²+8x+20=0

(−d−2)(d−10)=0

d=−2 or d=10

As number of days can not be negative. So, d = 10. Therefore,

The number of days taken by Anil to complete

the required work = 10 days

The number of days taken by Sunil to complete

the required work = d+5 = 15 days

Hence, Anil would take 10 days and Sunil would take 15 days to complete the work.

An airplane has 29 seats. The price for a coach seat is $600 in the price for a first class seat is $1050. The airline collected a total of $21,900 for the flight. How many coach seats were sold

Answers

Answer:

19 coach seats

Step-by-step explanation:

let the number of coach seats be C and number of first class seats be F

given that the total number of seats is 29,

C + F = 29 ---------(eq 1)

also given that each coach seat = $600, each 1st class seat is $1050 and a total of $21900 was collected,

600C + 1,050F = 21,900 -------(eq 2)

we have 2 equations and 2 unknowns, we can solve the system of equations by elimination

(eq 1) x 1,050 gives us:

1,050 (C + F) = 1,050(29)

1,050C + 1,050F = 30,450 ----- (eq 3)

by elimination, subtract eq 2 from eq 3

(1,050C + 1,050F) - (600C + 1,050F) = 30,450 - 21,900

1,050C - 600C = 8,550  

450C = 8550

C = 855 /450

C = 19

The radius of the given equation is 2 .

Step-by-step explanation:

The equation of a circle whose center (h, k) and radius is r,

(x - h)² + (y - k)² = r² ..............................(i)

Here given that-

x² + y² + 21 = 10 x

x² - 10 x + y² + 21 = 0

( To making perfect square, add and subtract 25 ) -

x² - 10 x + 25 - 25 + y² + 21 = 0

(x² - 10 x + 25) + y² -4 =0

[As we know that -

(x - 5)² = x² - 10 x + 25]

(x - 5 )² + y² = 4

(x - 5)² + (y - 0)² = 4

(x - 5 )² + (y- 0)² = 2² ................................(ii)

On comparing equation (i) and(ii)-

r = 2

Hence the radius of the given equation is 2 and center is ( 5, 0).

Suppose you have $30 to spend on a bag is tootsie rolls that are worth $3 and bags of lolli-pops worth $5.If you have to use all of their money , What combinations of candy bags can they buy ? Construct a liner equation and find /explain the y -intercept,x-intercept ,and slope

Answers

Answer:

Part a) [tex]3x+5y=30[/tex]

Part b) see the explanation

Part c) see the explanation

Step-by-step explanation:

Part a) Construct a liner equation

Let

x ----> the number of bags of  tootsie rolls

y ----> the number of bags of lolly-pops

we know that

The number of bags of tootsie rolls bought multiplied by their price ($3) plus the number of bags of lolly-pops bought multiplied by their price ($5) must equal $30

so

The linear equation that represent this problem is

[tex]3x+5y=30[/tex]

Part b) Find the intercepts

Find the y-intercept

The y-intercept is the value of y when the value of x s equal to zero

In this context, the y-intercept is the number of bags of lolly-pops that i can buy when the number of bags of tootsie rolls is equal to zero

For x=0

[tex]3(0)+5y=30[/tex]

[tex]y=6[/tex]

The y-intercept is the point (0,6)

so

I can buy 6 bags of lolly-pops and 0 bags of tootsie rolls

Find the x-intercept

The x-intercept is the value of x when the value of y s equal to zero

In this context, the x-intercept is the number of bags of tootsie rolls that i can buy when the number of bags of lolly-pops is equal to zero

For y=0

[tex]3x+5(0)=30[/tex]

[tex]x=10[/tex]

The x-intercept is the point (10,0)

so

I can buy 10 bags of  tootsie rolls and 0 bags of lolly-pops

Part c) Find the slope

we have

[tex]3x+5y=30[/tex]

isolate the variable y

[tex]5y=-3x+30[/tex]

[tex]y=-\frac{3}{5}x+6[/tex]

The slope is m=-3/5  ---> is negative because is a decreasing function        

That means ---> For every three less lollipops you get, you can have 5 more tootsie rolls

Six cars pull up to a red light, one at a time. At the light, there are three lanes, one left-turn lane, one straight-going lane, and one right-turn lane. How many ways can the cars stack up so that all three lanes are occupied? Note that if the first car turns left and the second goes straight, this is considered different from the first car going straight and the second car turning left. In other words, the cars are distinguishable, but pull up to the intersection in a fixed order.

Answers

Answer: [tex]540[/tex]

We count the number of ways that some lane can be left empty, and subtract from the total:

Each driver has three choices, so it's [tex]3^6 = 729[/tex].

Now, we count the ways where at least 1 lane is left empty:

But we have double-counted the situations where two lanes are left empty. Since each driver only has one choice, there are [tex]3(1^6)[/tex] situations we overcount. This leaves [tex]729 - (192 - 3) = 540[/tex] ways to fill all three lanes.

You mix 1/3
quart of blue paint for every 1/2
quart of red paint to make 2 1/2
quarts of purple paint. How much blue paint and how much red paint do you use?

Answers

Answer:

1 quart blue + 1 1/2 quart red

Step-by-step explanation:

Given:

Ratio of blue paint : red paint = 1/3 : 1/2

simplifying this ratio into whole numbers by multiplying both sides by 2 and 3, we get:

(1/3) x (3x2) : (1/2) x (3x2)

2 : 3

From this we can determine the fractions of red and blue paint used in any total purple mix

fraction of blue paint = 2/(2+3) = 2/5 of purple mix

fraction of red paint = 3/(2+3) = 3/5 of purple mix

we are given that we want to make 2 1/2  (= 5/2) quarts of purple paint

hence

amount of blue paint

= fraction of blue paint in purple mix x total amount of purple paint

= (2/5) x (5/2) = 1 quart

amount of red paint

= fraction of redpaint in purple mix x total amount of purple paint

= (3 /5) x (5/2) = 3/2 quart = 1 1/2 quart

a circle with radious of 1cm sits inside a 11cm times 12 cm rectangle what is the area of the shaded region

Answers

Answer: 128.86cm²

Step-by-step explanation:

The circle is inscribed in the rectangle. To find the shaded portion, subtract he area of the circle from the are of the rectangle.

Area of the rectangle                                  =  11 x 12

                                                                     =  132cm²

Area of the circle with radius of 1cm          =  πr²

                                                                     = 3.142 x 1²

                                                                     = 3.142cm²

Therefore , area of the shaded  region      = 132cm²  -  3.142cm²

                                                                    = 128.86cm²

Answer:128.86
