Answer:

10 cm is your answer right answer

Answer:

40 m²

Step-by-step explanation:

First, find the perimeter. Using the perimeter formula, p = 2l + 2w, solve for the side lengths of the length and width.

Let w represent the width. The length can be represented by w + 3, since the length is 3 m longer than the width.

Plug in 26 as the perimeter, and plug in w and w + 3 for the width and length:

p = 2l + 2w

26 = 2(w + 3) + 2w

Simplify and solve for w:

26 = 2w + 6 + 2w

26 = 4w + 6

20 = 4w

5 = w

Find the length by adding 3 to this:

5 + 3

= 8

Now, find the area using the area formula, A = lw

Plug in the length and width:

A = lw

A = 8(5)

A = 40

So, the area of the rectangle is 40 m²

Answer:

y=2/3x-2

Step-by-step explanation:

y-y1=m(x-x1)

y-(-6)=2/3(x-(-6))

y+6=2/3(x+6)

y=2/3x+12/3-6

y=2/3x+4-6

y=2/3x-2

Answer:

Ali ran 25.13 m more than bily

Step-by-step explanation:

From the diagram, we can see that bully runs with the inner track line while Ali runs with the outer track line.

Thus;

Diameter of inner semi circle = 20 m

Diameter of outer semi circle = 20 + 4 + 4 = 28 m

Perimeter of inner semi circle = πD/2 = 10π

Perimeter of outer semi circle = πD/2 = 14π

Now, perimeter of Billy = 80 + 80 + 10π + 10π = 222.83 m

Perimeter of Ali = 80 + 80 + 14π + 14π = 247.96 m

Thus, in one lap, difference in distance between Ali and billy = 247.96 - 222.83 = 25.13 m

Cars with ABS or anti-lock brakes do not leave skid marks is a false statement.

Four-wheeled vehicle designed primarily for passenger transportation and commonly propelled by an internal-combustion engine using a volatile fuel.

Cars with ABS or anti-lock brakes are designed to prevent skidding during sudden braking.

However, it is not entirely true that they do not leave skid marks.

Skid marks can still be present, especially in certain situations such as emergency braking on a wet or slippery road surface.

ABS helps to prevent the wheels from locking up, which can reduce the length of skid marks, but they may still be present to some extent.

Therefore, it is not accurate to say that cars with ABS or anti-lock brakes do not leave skid marks, so it is false.

Answer:

c.  40.32%

Step-by-step explanation:

Given:

Loss percent is 13%.

Selling price = 1475

To find:

The loss or gain if the goods are sold for Rs.1615?

Solution:

Let x be the cost price of goods.

Loss percent is 13% and selling price is 1475.

[tex]1475=x-\dfrac{13}{100}x[/tex]

[tex]1475=x-0.13x[/tex]

[tex]1475=0.87x[/tex]

[tex]\dfrac{1475}{0.87}=x[/tex]

[tex]1695.4023=x[/tex]

[tex]x\approx 1695.40[/tex]

The cost price of goods is 1695.40.

We need to find the loss or gain if the goods are sold for Rs.1615.

Cost price is greater than the selling price because 1695.40 > 1615. It means , it is a loss.

[tex]Loss=CP-SP[/tex]

[tex]Loss=1695.40-1615[/tex]

[tex]Loss=80.40[/tex]

The loss percent is

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

[tex]Loss\%=\dfrac{80.40}{1695.40}\times 100[/tex]

[tex]Loss\%\approx 4.74\%[/tex]

Therefore, the loss is 80.40 and the loss percent is about 4.74%.

Step-by-step explanation:

The time perry used is 7/8 of a minute

a minute equals to 60 seconds

so the time perry used is 7/8 x 60 = 52.5 seconds

The winner used 14/15 of 52.5 seconds (perrys time)

so 14/15 x 52.5 = 49 seconds

Answer:

Step-by-step explanation:

The equation of a line with a slope of "a" and containing a given point (x₀, y₀) is:

y - y₀ = a(x - x₀)

a = 11,  x₀ = -7,  y₀ = -1

So:

y - (-1) = 11(x - (-7))  

y = 11x + 77 - 1

y = 11x + 76

Answer:

a. $256

Step-by-step explanation:

The computation of the maximum allowable recurring debt is shown below:

Given ratio = 28:36

And the monthly income is $3,200

So the maximum expense on housing = 28% of $3,200 = $896

And, the maximum expense on total debt = 36% of $3,200 = $1,152

Now the maximum alloweable recurring debt is

= $1,152 - $896

= $256

Explanation:

The term with the largest exponent will go first, followed by the next largest exponent, and so on. This will get the polynomial into standard form. So 4+5x^2-x turns into 5x^2-x+4. You can think of this as 5x^2-x^1+4x^0. Note the exponents counting down: 2,1,0.

Each term is separated by a plus or a minus. We can think of 5x^2-x+4 as 5x^2+(-x)+4

The leading term is the first term 5x^2. It has the coefficient of 5, so the leading coefficient of the overall polynomial is 5.

The constant is the term without any variables attached to it. So the constant is 4. As the name implies, the constant doesn't change no matter what x changes to. In contrast, the 5x^2 term does change as x changes.

The degree is the largest exponent, so in this case it would be 2. After you get the polynomial into standard form, it's the first exponent on the left.

As mentioned earlier, each term is separated by a plus or a minus. So we have three terms here. We consider this a trinomial since "tri" means "three". More specifically, this is a quadratic trinomial. Any quadratic will have the largest exponent being 2.
