The length of a rectangle is 15cm more than its width and perimeter is 150cm. Find the length and width of the rectangle.

Pls help as I'm preparing for my exams

Answers

Answer 1

Answer:

Hope this helps you..

Brainliest plsssss

All the Best for your exams

Step-by-step explanation:

let the breadth=x

the length  =x+15

given perimeter= 150

Perimeter of rectangle = 2x(l+b)

150 = 2( x+ x+15)                            

75 = 2x +15

60 = 2x

30=x  

therefore breadth = 30 cm  

length   = 30 +15  = 45 cm

Verification:

150 = 2( 45+30)

150 = 2(75)

150 = 150  

LHS=RHS

Hence, proved..

Answer 2

Answer:

Step-by-step explanation:

Let the breadth(b) be x . Then by the question

Length (L) = ( x + 15 )cm

Perimeter = 150 cm

or 2( L + b) = 150

2 ( x + 15 + x ) = 150

2x + 15 = 75

2x = 75 - 15

2x = 60

x = 30 cm

Therefore breadth or width is 30 cm

Similarly

Length = 30 + 15 = 45

hope it helps :)

Answers

Answer:

The surface area of the shape is 292 in^2

Step-by-step explanation:

Here, we want to find the surface area of the cuboidal shape

Mathematically, the area of a cuboid can be calculated using the formula;

A = 2(lb + lh + bh)

where l is the length which is 7 inches

b is the breadth which is 6 cm

h is the height which is 8 cm

Substituting these values, we have

A = 2((8 * 6) + (7 * 6) + (8 * 7))

A = 2(56 + 42 + 48)

A = 2 * 146

A = 292 in^2

N January, the price of a dozen eggs at a grocery store was $0.89. By June, the price had increased to $0.99. What was the percent of increase in the price, to the nearest tenth of a percent?

Answers

11.236% increase
hope this helped

The initial price of eggs is $0.89 which is then increased to $0.99, so the percentage increase in the price is 11.23%.

What is Percentage?

The Latin term "per centum," which signifies "by the hundredth," was the source of the English word "percentage." Segments with a denominator of 100 are considered percentages. In other terms, it is a relationship where the worth of the entire is always considered to be 100.

As per the given data in the question,

The price of dozen eggs = $0.89

The price increase by June = $0.99

The percentage increase in the price,

% increase = (0.99 - 0.89)/0.89 × 100

% increase = 11.2%

Therefore, the increase is 11.2%.

please help!!!!!!

Answers

Answer:

DP = 15.

Step-by-step explanation:

I am assuming that DP EP and FP are peroemdicular bisectors of the sides of ABC.

D is the midpoint of AB so

2x + 14 = 8x - 52

14+52 = 8x - 2x

6x = 66

x = 11.

So side AD = 2(11) + 14 = 36.

Now PC = PA = 39.

So by pythagoras:

DP^2 = AP^2 - AD^2

= 39^2-36^2 = 225

DP = sqrt 225

= 15.

The volume is 3150 cubic feet

Answer:

3150 ft³

Step-by-step explanation:

Since this is a rectangular prism, we need to do length × width × height to find the volume. Now despite the shape being tilted at an angle, nothing is different.

So we can see that the length is 25, the width is 18 and the height is 7

Rewrite the formula for volume replacing variables

25 × 18 × 7

Now solve.

25 × 18 = 450

450 × 7 = 3150

Now before we finalize our answer, there are two more things we need to do.

We need to add the measurement unit which is feet or ft

We also need to add ³ since it is volume

Add both of these to the end

3150 ft³ is your final answer

Answers

Answer:

x=5, y=6

Step-by-step explanation:

7x+2y=47

5x-4y=1

to use elimination method , you want to add the two equations together so that either x or y cancels out. For these equations, we will multiply the first equation by 2. (This will cancel out y value)

2(7x+2y)=2(47)

14x+4y =94

————————

add above equation to second equation:

14x+4y=94 above equation

5x-4y=1 second equation

19x=95 added together

x=5

—————————————

‘solve for y by substituting x value (5) into either original equation

5x-4y=1

5(5)-4y=1

25-4y=1

-4y=-24

y=6

Efectivamente, la suma de la medida de los ángulos internos de cualquier figura triangular es igual a 180º. Ahora bien, la oración posee un error de redacción, pues tanto los triángulos rectos como los equiláteros o los isósceles poseen dicha característica, es decir, no es únicamente una característica de los triángulos rectos. Además, la suma de los ángulos interiores de dos triángulos rectos sería igual a 360º, no a 180º.
