It's gonna be an irrational number because the length of the hypotenuse is 6.40312....... cm

[tex] {4}^{2} + {5}^{2} = {41}^{2} [/tex]

[tex] \sqrt{41} = 6.403124237[/tex]

An irrational number cannot be written as a simple fraction and the decimals would keep on going without a pattern (if it was repeating, it would be rational).

Answer:

If the legs are equal to 4 cm and 5 cm, respectively we can rewrite the equation 42+52=c2 -> 16+25=41=c^2 so then, c= the square root of 41, which is an irrational number.

Hope this helps!

The act of factoring is to reduce numbers down to their prime number.

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

A prime number is a positive integer having exactly two factors that are 1 and the number itself. Any number that does not follow this is termed a composite number.

For example:

Let the number 2310, then the factor of the number 2310 will be

2310 = 2 × 3 × 5 × 7 × 11

Where, 2, 3, 5, 7, and 11 are the prime numbers.

Answer:

16.5

Step-by-step explanation:

A is the correct answer

Step-by-step explanation:

If you plug y=x+10 in for the Y variable you just have to solve by multiplying.

1.) It should look like this:

2x + 3(x +10) = 40

2.) You will distribute the three which will make the equation look like this:

2x + 3x + 30 = 40

3.) Add like terms. Then subtract 30 from both sides. Then divide 5 by both sides to get the variable x alone.

but 16.5 is the answer

Step-by-step explanation:

The parameters of the workers in the office are;

The number of staffs in the office = 60 staffs

The take-aways are pizza, curry, fish & chips, kebab and other

The frequency for the above take-aways = 14, 6, 4, 14, and 22 respectively

The variables for the angles representing the above take-aways on the pie chart = 'a', 'b', 'c', 'd', and 'e'; respectively

In order to find the size of the angles that represent each group of workers in the pie chart, we find the ratio of the group size to the total number of workers and we multiply the result by 360° as follows;

∠a = 360° × 14/60 = 84°

∠b = 360° × 6/60 = 36°

∠c = 360° × 4/60 = 24°

∠d = 360° × 14/60 = 84°

∠e = 360° × 22/60 = 132°

The equation of the line that passes through the points

(5,-5) and (-5,-1)  is  y=-2/5x-3.

Answer:

37°

Step-by-step explanation:

(4x + 2)° = 150° [Vertically Opposite Angles]

=> 4x = 150 - 2

=> 4x = 148

[tex] = > x = \frac{148}{4} [/tex]

=> x = 37° (Ans)

Angle (4x+2)° and angle 150° are vertically opposite angles so, their measures will be equal.

Which means :

[tex] =\tt 4x + 2 = 150[/tex]

[tex] =\tt 4x = 150 - 2[/tex]

[tex] = \tt4x = 148[/tex]

[tex] =\tt x = \frac{148}{4} [/tex]

[tex]\hookrightarrow \: \color{plum}x = 37[/tex]

Let us check whether or not we have found out the correct measure of x by placing 37 in the place of x:

[tex] =\tt 4 \times 37 + 2 = 150[/tex]

[tex] = \tt148 + 2 = 150[/tex]

[tex] =\tt 150 = 150[/tex]

Since the measures of both the angles are equal we can conclude that we have found out the correct value of x.

Thus, the value of x in this figure = 37

Therefore, the correct option is (A) 37.

Answer: 4.8x+3

Step-by-step explanation:

The portion of the phone that is not occupied by the screen is 4.9x + 3 cm².

For each three-dimensional geometrical shape, surface area and volume are determined. The area or region that an object's surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has. There are numerous shapes and dimensions in geometry, including sphere, cube, cuboid, cone, cylinder, etc. Each form has its own volume and surface area. Nevertheless, we can only estimate the area that two-dimensional figures like a square, circle, rectangle, triangle, etc. cover; there is no volume available.

As per the given data:

The width of the screen = x cm

Height of the screen = 1.9 times the width = 1.9x

Dimensions of the phone are given in the diagram.

The area of the screen = height × width

= 1.9x × x = 1.9x² cm²

The area of the phone = (1.9x + 3)(x + 1)

= 1.9x² + 1.9x + 3x + 3

= 1.9x² + 4.9x + 3 cm²

Area of the phone not occupied by screen:

= area of the phone - area of the screen

= 1.9x² + 4.9x + 3 - 1.9x²

= 4.9x + 3 cm²

Hence, the portion of the phone that is not occupied by the screen is 4.9x + 3 cm².

Charles bought 60 packs

60 packs x 12 pens = 720 pens

Step 2: Find out how much Charles spent

2.80 per pack

Charles bought 60 packs

60 x 2.80 = 168 pounds

Step 3: Find out how many pens Charles sold

Charles sold 2/3 of his pens

2/3 x 720 = 480

Step 4: Find out how manypens he sold

Charles sold the pens for 40p

40p x 480 = 19200p

Step 5: Convert pences to pounds

19200p = 192 pounds

Step 6: Find the profit

192 - 168 = 24 pounds

formula to find area of a triangle:

A=1/2 × base × height(h)

insert the values into the formula:

24=1/2 × 4 × h

solve for h :

24=2h

24/2=h

h = 12 cm ( Ans )

The height of triangle will be 12 cm.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

The triangle has a base length of 4 cm.

And, A total area of 24 cm².

Now,

We know that;

Area of right triangle = 1/2 × Base × Height

⇒ 24 = 1/2 × 4 × h

⇒ 24 = 2 × h

⇒ h = 24 / 2

⇒ h = 12 cm

Thus, The height of triangle = 12 cm.

Answer:

The first six terms of the sequence [tex]f\left(n\right)=\left(-3\right)^n[/tex] are:

[tex]-3, 9, -27, 81, -243, 729[/tex]

Step-by-step explanation:

Given the sequence

[tex]f\left(n\right)=\left(-3\right)^n[/tex]

Here [tex]n[/tex] represents any term number in the sequence

Determining the first term

substitute n = 1 in the sequence to determine the first term

[tex]f\left(n\right)=\left(-3\right)^n[/tex]

[tex]\:f\left(1\right)=\left(-3\right)^1[/tex]

[tex]f\left(1\right)=-3[/tex]

Thus, the first term is -3.

Determining the 2nd term

substitute n = 2 in the sequence to determine the 2nd term

[tex]f\left(n\right)=\left(-3\right)^n[/tex]

[tex]\:f\left(2\right)=\left(-3\right)^2[/tex]

[tex]\:f\left(2\right)=9[/tex]

Thus, the 2nd term is 9.

Determining the 3rd term

substitute n = 3 in the sequence to determine the 3rd term

[tex]f\left(n\right)=\left(-3\right)^n[/tex]

[tex]f\left(3\right)=\left(-3\right)^3[/tex]

[tex]f\left(3\right)=-27[/tex]

Thus, the 3rd term is -27.

Determining the 4th term

substitute n = 4 in the sequence to determine the 4th term

[tex]f\left(n\right)=\left(-3\right)^n[/tex]

[tex]f\left(4\right)=\left(-3\right)^4[/tex]

[tex]f\left(4\right)=81[/tex]

Thus, the 4th term is 81.

Determining the 5th term

substitute n = 5 in the sequence to determine the 5th term

[tex]f\left(n\right)=\left(-3\right)^n[/tex]

[tex]f\left(5\right)=\left(-3\right)^5[/tex]

[tex]f\left(5\right)=-243[/tex]

Thus, the 5th term is -243.

Determining the 6th term

substitute n = 6 in the sequence to determine the 6th term

[tex]f\left(n\right)=\left(-3\right)^n[/tex]

[tex]f\left(6\right)=\left(-3\right)^6[/tex]

[tex]f\left(6\right)=729[/tex]

Thus, the 6th term is 729

Therefore, the first six terms of the sequence [tex]f\left(n\right)=\left(-3\right)^n[/tex] are:

[tex]-3, 9, -27, 81, -243, 729[/tex]

The (45,3) and (30,0) are the correct-ordered pairs that correspond to input-output pairs for the function.

Each element of X receives exactly one element of Y when a function from one set to the other is used. The sets X and Y are collectively referred to as the function's domain and co-domain, respectively.

Given the function:

y = 5t +30,

Here y is the no of gallons and t is the time.

Take the values of option A and substitute in the function,

45 = 5 × 3 +30

45 = 45

Hence, it is the correct-ordered pair,

Similarly, take option b

3 = 45 × 5 +30

3 ≠ 255

Now take option c,

0 = 30 × 5 +30

0 ≠ 180

Take the last option,

30 = 0 × 5 +30

30 = 30

Hence, it is also the ordered pair.

Therefore, the (45,3) and (30,0) are the correct-ordered pairs that correspond to input-output pairs for the function.
