Find the perimeter of the rectangle

Answer:

Angle B = 24°

Step-by-step explanation:

Given:

that means, Angle A = 5 ( Angle B + 7.2 )

Now,

Let Angle B = x (say)

•.• Angle A = 5 ( x + 7.2 )

Therefore, As it is given that the angles are supplementary , the sum of Angle A and Angle B will be equal to 180°.

Angle A + Angle B = 180°

[tex]⇢x + 5(x + 7.2) = 180[/tex]

[tex]⇢x + 5x + 36 = 180[/tex]

[tex]⇢6x = 180 - 36[/tex]

[tex]⇢6x = 144[/tex]

[tex]⇢x = \frac{144}{6} [/tex]

Now, substituting the value of x. . .

Thus, Angle B comes out 24°

Step-by-step explanation:

Kiran can know for sure that it is incorrect by substituting x with 1/4

Solving for the equation gives 4(1/4 + 3) = 7
distributing gives 1 + 3 = 7
obviously this is incorrect

b)
Andre's error is that he didnt distribute 7
Distributing 7 results in
4x + 12 = 7
then subtracting 12 from both sides
4x = -5
x = -5/4

Answer:

x=-1.25

Step-by-step explanation:

well he was wrong about the 4x = 1.

4(x+3)=7

4x+12=7    1. - 12 on both sides

4x=-5   2. 4 on both sides

x=-1.25

A rectangle with proportions close to the Golden Ratio of approximately 1:1.618 is believed to be aesthetically pleasing.

A rectangle with sides that are in the golden ratio, or roughly 1:1.618, is referred to as a golden rectangle. This ratio has been employed in art, architecture, and design for ages since it is seen to be aesthetically beautiful.

To build a golden rectangle, start with a square and then add a smaller square to one of its sides to form a rectangle. The smaller rectangle is then used to repeat this procedure until you obtain a rectangle whose sides are in the golden ratio.

The layout of credit cards is one instance of a situation in real life that makes use of a golden rectangle. Golden rectangles are a popular shape for credit cards because of their attractive proportions and visual balance. A golden rectangle may also be used in credit card designs to help the card stand out from other cards and be simpler to recognize. The dimensions of several paintings, sculptures, and structures are more instances of how golden rectangles are used in the design.

Formula for the circumference of a circle = pi x 2 x radius

Circumference = 3

pi = 3.14

radius = r

---To find the radius, we will need to solve for it. Start by plugging in what we know.

3 = 3.14 x 2 x r

---Simplify by multiplying 3.14 by 2

3 = 6.28 x r

---Divide both sides by 6.28 to solve for r

r = 3 / 6.28 = 0.4777

---Round the decimal to the nearest tenth

r = 0.5

In the Triangle BCD, Angle B is 90° since tangent and radius are perpendicular to one another.

Now, let's find Angle C using Angle sum property of a triangle.

[tex]\qquad \tt \dashrightarrow \:\angle C + \angle B + \angle D = 180[/tex]

[tex]\qquad \tt \dashrightarrow \:\angle C + 90 + 45= 180[/tex]

[tex]\qquad \tt \dashrightarrow \:\angle C + 135= 180[/tex]

[tex]\qquad \tt \dashrightarrow \:\angle C= 180 - 135[/tex]

[tex]\qquad \tt \dashrightarrow \:\angle C= 45 \degree[/tex]

Now, we know that Angle made by an arc on the centre is twice the Angle made by same arc on boundary of circle, hence we can infer that :

[tex]\qquad \tt \dashrightarrow \:2\angle C = 10x[/tex]

[tex]\qquad \tt \dashrightarrow \:10x = 2 \times 45[/tex]

[tex]\qquad \tt \dashrightarrow \:x = 90 \div 10[/tex]

[tex]\qquad \tt \dashrightarrow \:x = 9[/tex]

So, the required value of x is 9

The percent of children who are between the ages 5 and 10 will have their birthday party at home is 10.91%.

Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.

Percentage is usually denoted by the symbol '%'.

Given that,

There are total of 325 children in different ages who have their birthday party in different ways.

Number of children in between the ages 5 and 10 = 110

Number of children of the ages 5-10 who have their birthday party at home = 12

In order to find the percentage, divide part with the whole.

Percentage = 12 / 110 = 0.1091

Percentage is 10.91%

Hence the required percentage is 10.91%.

The solution to the given system of equations is the point (1, 5).

Here we have the system of equations:

g(x) = 3x + 2

f(x) = |x - 4| + 2

To solve this, first you can see where the graphs intercept on the graph (the intercept point is the solution to the system)

But we can also solve it analytically. To do it, we have:

g(x) = f(x)

3x + 2 =  |x - 4| + 2

3x =  |x - 4|

Notice that the only solution of the above equation is x = 1, so we know that it is the x-value of the solution.

To get the y-value, we just evaluate one of the two given functions on x = 1.

f(1) = |1 - 4| + 2= 3 + 2 = 5

Then the solution to the system is the point (1, 5).

Answer:

C

Step-by-step explanation:

Use the pythagorean theorem.

32^2+b^2=48^2

1024+b^2=2304

Subtract 1024

b^2=1280

Square root

b=sqrt(1280)

Now simplify sqrt(1280)

sqrt(1280) = sqrt(256*5)

You can take the square root of 256 since it is a perfect square so take it out of the radical.

sqrt(256*5)=16sqrt(5)
