Answer:

$14.4

Step-by-step

c = x + 0.07x + 0.18x

18 = x + 0.07x + 0.18x

18 = 1.25x (simplify)

14.4 = x  (divide both sides by 1.25)

Answer:

Step-by-step explanation:

A rational number is one that can be expressed as a fraction. Pi cannot be. If I tell you that the 2000th digit of pi is an 8 (which it probably isn't) and I ask you to tell me the 2001 value of pi, you have no better odds that 1/10 of getting it right.

A rational number can always be reduced to a fraction. 20 1/2 can be expressed as a fraction. It is 20.5

Pi is irrational. I don't know the value of pi beyond what a calculator can tell me.  3.14159265 The next digit is a 4. I know this only because that is what the calculator tells me.

Repeating decimals call always be represented as a fraction. For ex

x = 0.123123123123123

1000x = 123.123123123123

       x =       .123123123123123      Subtract

999x = 123

This comes about because in both cases what is after the decimal is the same.

x = 123/999 = 41/333

Answer:

135c^7

Step-by-step explanation:

[tex]135c^7[/tex] is the simplified equation of the given expression.

Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.

To simplify [tex]5c(3c^2)^3[/tex], we need to apply the power rule of exponents, which states that [tex](a^m)^n = a^{(m*n)[/tex].

In this case, we have [tex](3c^2)^3[/tex], which means we need to multiply the exponent 3 by the exponent 2, giving us 6. So, we can rewrite the expression as:

[tex]5c(3c^2)^3 = 5c(3^3c^{(2*3)})[/tex]

Simplifying further, we get:

[tex]5c(3^3c^6) = 5c(27c^6)[/tex]

Finally, we can simplify by multiplying 5 and 27, and adding the exponents of c:

[tex]5c(27c^6) = 135c^{(1+6)} = 135c^7[/tex]

Therefore, [tex]5c(3c^2)^3[/tex] simplifies to [tex]135c^7[/tex].

Answer/Step-by-step explanation:

Area of trapezium = ½*(AD + BC)*AB

Area = 42 cm²

AD = (x + 8) cm

BC = (x + 5) cm

AB = x cm

Plug in the values into the equation

42 = ½((x + 8) + (x + 5))*x

42 = ½((x + 8 + x + 5)*x

42 = ½(2x + 13)*x

Multiply both sides by 2

42*2 = (2x + 13)*x

84 = 2x² + 13x

2x² + 13x = 84

Subtract both sides by 84

2x² + 13x - 84 = 0

Explanation:Solve for x by simplifying both sides of the inequality, then isolating the variable.

Answer:

1 = 50°,  2 = 130°,  3 = 50°,  4 = 130°,  5 = 40°,  6 = 140°,  7 = 90°,  8 = 140°

Step-by-step explanation:

The sum of the angles of a triangle is 180°. A flat angle measures 180° as well.

Angle 1: 180 - 90 - 40 = 50°

Angle 2: 180 - 50 = 130°

Angle 3: 180 - 130 = 50°

Angle 4: 180 - 50 = 130°

Angle 5: 180 - 90 - 50 = 40°

Angle 6: 180 - 40 = 140°

Angle 7: 180 - 90 = 90°

Angle 8: 180 - 40 = 140°

Answer:

80.4

Step-by-step explanation:

Use the tan formula

The value of X is approximately 80.38 units.

Here, we have,

To find the value of X, we can use trigonometric functions.

In this case, we'll use the tangent function, which relates the angle and the sides of a right triangle.

The tangent of an angle is defined as the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.

In this scenario, we have the angle between the hypotenuse and the base as 15°, and the base of the triangle is given as 300 units.

Using the tangent function, we can set up the equation:

tan(15°) = X / 300

Now, let's solve for X:

X = 300 * tan(15°)

Using a calculator, we find:

X ≈ 80.384

Rounding to the nearest tenth, the value of X is approximately 80.38 units.

Answer:

0.20148

Step-by-step explanation:

We solve using z score formula

z = (x-μ)/σ, where

x is the raw score = 230

μ is the population mean = 184

σ is the population standard deviation = 55

z = 230 - 184/55

z = 0.83636

P-value from Z-Table:

P(x<230) = 0.79852

P(x>230) = 1 - P(x<230) = 0.20148

Therefore, the probability that the eye contact time is greater than 230 seconds is 0.20148

Answer: Dhs 29312.4

Step-by-step explanation:

For a leap year, we should note that there are 366 days. Since there were 52 Sundays, the number of days worked by Aden will be:

= 366 - 52

= 314 days

Since she got Dhs 354003 as her annual salary last year, the amount received per day will be:

= 354003 / 314

= Dhs 1127.4

The amount earned in March will be:

= (31 - 5) × 1127.4

= 26 × 1127.4

= Dhs 29312.4
