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

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

Jumper costs £13

Step-by-step explanation: (s = shirt j = jumper)

We know that 2s + 1j = £29

We also know that 1s + 1j = £21

29-21 = £8

This means that the shirts cost £8  each

We now need to multiply: 8 x 2 = £16  which means that the shirts in total cost £16

So, 29 - 16 = £13  which means one jumper costs £13

The cost of one jumper is $13.

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that, two shirts and one jumper cost £29 while one shirt and one jumper cost £21, we need to find the cost of one jumper,

Let jumper is represented by j and that of shirt by s,

Establishing the equations,

2s + j = 29

j = 29 - 2s......(i)

s + j = 21

j = 21 - s.......(ii)

Solving the equations,

21 - s = 29 - 2s

s = 8

Put s = 8 in eq (ii)

j = 21 - 8

j = 13

Hence, the cost of one jumper is $13.

Answer:

x/121 + y/9 = 1

Step-by-step explanation:

The major axis is 22 units long, in a horizontal line, and the center is in the middle of the major axis line segment. The center is at the origin. The distance of the whole axis is 22, and its endpoints are 11 units from the center. The axis length is 2a = 22, so a = 11.

Becasue the major axis is horizontal, this ellipse is wider than it is tall.

The minor axis is perpendicular to the major axis and it always shoter (hence the name 'minor'). In this case, it is vertical, is 6 units long, so we say that 6 = 2b, and b = 3.

The ellipse center is (h,k). But in this case, the center is the origin, so h = 0 and k = 0.

The equation for a horizontal ellipse is (x-h)²/a² + (y-k)²/b² = 1, a>b

(x-0)²/11² + (y-0)²/3² = 1

*** x/121 + y/9 = 1

The equation for a vertical ellipse is (x-h)²/b² + (y-k)²/a² = 1, a>b

If the bigger denominator is under 'x' term the ellipse is horizontal, with the longer axis being horizontal.

If the bigger denominator is under the 'y' term, the ellipse is vertical, with the longer axis being vertical.

Answer:

y= -2/3x-3

Step-by-step explanation:

Formula of volume of a Sphere is : V = 4/3 πr³

Here, Diameter (2r) = 12, so radius (r) = 12/2 = 6 feet

Substitute it into the formula,

V = 4/3 π(6)³

V = 4/3 *216π

V = 288π Ft² [ Answer in the term of π ]

You can also solve it for numeral value by substituting the value of π = 22/7

V = 288 * 22/7 = 905.15 Ft² [ Answer in numbers ]

Answer:

288 pi ft squared

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%.

Answer:

The two angles are 85 and 95 degrees

Step-by-step explanation:

Supplementary angles add to 180

Let x be one angle

The supplement is 10 less,  ( x-10)

They add to 180

x+ ( x-10) = 180

2x -10 = 180

Add 10 to each side

2x-10+10 =180-10

2x= 190

Divide by 2

2x/2 =190/2

x=95

The other angle is 95-10 = 85

The two angles are 85 and 95 degrees

Answer:

15 mph

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.

Answer:

1.   2x + 8y = 10xy

2.   13ab + 15ab = 28ab

Step-by-step explanation:

  This is because for question 2 the "a" and "b" stay together since it's on 13 and 15. So that is why you would get 28ab. For question 1 it's basicly the same but instead, you combine the two to get your answer.

Complete Question:

There are 10 marbles. What is the probability of drawing 2 blue marbles if the first marble is NOT placed back in the bag before the second draw.

2 yellow, 3 pink, 5 blue    

Answer:

[tex]P(B_1\ and\ B_2) = \frac{2}{9}[/tex]

Step-by-step explanation:

Given

[tex]Blue = 5[/tex]

[tex]Pink = 3[/tex]

[tex]Yellow = 2[/tex]

[tex]Total = 10[/tex]

When the first blue marble is selected, the probability is:

[tex]P(B_1) = \frac{n(Blue)}{Total}[/tex]

[tex]P(B_1) = \frac{5}{10}[/tex]

Since the first marble is not returned, we have the following marbles left

[tex]Blue = 4[/tex]

[tex]Pink = 3[/tex]

[tex]Yellow = 2[/tex]

[tex]Total = 9[/tex]

The probability of picking a second blue marble is:

[tex]P(B_2) = \frac{n(Blue)}{Total}[/tex]

[tex]P(B_1) = \frac{4}{9}[/tex]

So, the required probability is:

[tex]P(B_1\ and\ B_2) = P(B_1) * P(B_2)[/tex]

[tex]P(B_1\ and\ B_2) = \frac{5}{10} * \frac{4}{9}[/tex]

[tex]P(B_1\ and\ B_2) = \frac{5*4}{10*9}[/tex]

[tex]P(B_1\ and\ B_2) = \frac{20}{90}[/tex]

[tex]P(B_1\ and\ B_2) = \frac{2}{9}[/tex]
