A CFL football player has an annual salary of $305 000. The player donates 1/8 of his salary to charity . What amount is this ?

Answer:

25 percent.

Step-by-step explanation:

25 divided by 100 is equal to 0.25. You then multiply that by 100 to get percent, which is 25 percent.

In this case, they are both centimetres, so they remain constant. The true size, 15km, is then multiplied by 13/ 1. Then, 20 × 13 = 195. As a result, the answer is 195 kilometres.

Therefore,

The map has a scale  = 1 cm

Corresponds to  = 15 kilometers

Map centimeters apart​ = 13 cm

Then you simply multiply the true size

= 15km, by 13/ 1.

Then, 20 x 13 = 195.

Hence, the answer is 195 kilometers.

The  total cost for the group of ten people after discount is 10 t - 0.5 t.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Discount = 5%

Total tickets= 10

We have t represents the cost of one ticket.

So, For 10 person the cost of the ticket = 10t

Now, after discount the price of tickets

= 5% of 10t

= 0.5 t

Hence, the total cost for the group of ten people after discount is 10 t - 0.5 t.

[tex]\textsf{Factored function}: \quad f(x)=(x+2)(3x-5)(x-1)[/tex]

[tex]\textsf{Zeros}: \quad x=-2, \quad x=\dfrac{5}{3},\quad x=1[/tex]

Step-by-step explanation:

Given function:

[tex]f(x)=3x^3-2x^2-11x+10[/tex]

If (x + 2) is a factor then:

[tex]\implies f(x)=(x+2)(ax^2+bx+c)[/tex]

Expand:

[tex]\implies f(x)=ax^3+bx^2+cx+2ax^2+2bx+2c[/tex]

[tex]\implies f(x)=ax^3+2ax^2+bx^2+2bx+cx+2c[/tex]

[tex]\implies f(x)=ax^3+(2a+b)x^2+(2b+c)x+2c[/tex]

To find a, compare the coefficients of x³:

[tex]\implies a=3[/tex]

To find b, substitute the found value of a into the coefficient for x² and compare:

[tex]\implies 2a+b=-2[/tex]

[tex]\implies 2(3)+b=-2[/tex]

[tex]\implies b=-8[/tex]

To find c, compare the constants:

[tex]\implies 2c=10[/tex]

[tex]\implies c=5[/tex]

Therefore:

[tex]\implies f(x)=(x+2)(3x^2-8x+5)[/tex]

Now factor (3x²-8x+5):

[tex]\implies 3x^2-3x-5x+5[/tex]

[tex]\implies 3x(x-1)-5(x-1)[/tex]

[tex]\implies (3x-5)(x-1)[/tex]

Therefore the factored function is:

[tex]\implies f(x)=(x+2)(3x-5)(x-1)[/tex]

Zero Product Property

[tex]\boxed{\text{If \; $a \cdot b = 0$ \; then either \; $a = 0$ \;or \;$b = 0$ (or both)}.}[/tex]

To find the zeros, set each factor equal to zero and solve for x:

[tex]\implies x+2=0 \implies x=-2[/tex]

[tex]\implies 3x-5=0 \implies x=\dfrac{5}{3}[/tex]

[tex]\implies x-1=0 \implies x=1[/tex]

Therefore, the zeros of the function are:

[tex]x=-2, \quad x=\dfrac{5}{3},\quad x=1[/tex]

The distance of all the side of ΔABC and ΔA'B'C' are equal which makes them congruent triangles.

What is congruent triangles?

When all 3 corresponding sides and every one 3 corresponding angles area unit equal in size, 2 triangles area unit aforementioned to be congruent.

Main Body:

First let us find the co-ordinates of both the triangles.

A= (3,5)

B = (-2, 3)

C= (-4,-1)

A' =(10,-5)

B'= (5, -3)

C' =(3,1)

Distance between two points =  d=√((x₂ – x₁)² + (y₂ – y₁)²).

In ΔABC

Distance of side AB =  √((3 –(-2) )² + (5 –3 )²)

                                 = √5² +2²

                                 = √29

Distance of side BC = √((-2-(-4) )²+ (3 -(-1 )²)

                                 = √20

Distance of side CA = √((3-(-4) )² + (5-(-1) )²)

                                 = √7² + 6²

                                 = √85

Distance of side A'B' = √((10 -5)² + (-5-(-3))²

                                   = √(5² +2²)

The 2.51 × 10⁻⁵ Watts/cm² sound intensity of the sound from the rocket engine has a decibel level of 114 dB

A decibel is a unit to measure the relative loudness of sound or to express the ratio electrical or acoustic power.

The intensity of the sound of the rocket engine = 2.51 × 10⁻⁵ Watts/cm²

Converting the unit of the sound intensity to Watts/m² gives;

1 cm² = 0.0001 m²

10,000 cm² = 1 m²

2.51 × 10⁻⁵ Watts/cm² = 10000 × 2.51 × 10⁻⁵ Watts/m² = 0.251 Watts/m²

The equation for the decibel from the power of sound is presented as follows;

[tex]\beta\ (dB)=10\cdot log_{10}\left(\dfrac{I}{I_0} \right)[/tex]

Where;

I₀ = 10⁻¹² W/m²

Which gives;

[tex]\beta\ (dB)=10\cdot log_{10}\left(\dfrac{0.251 }{10^{-12}} \right) = 113.9967373215 \approx 114[/tex]

An equilateral triangle in geometry is a triangle with three equal-length sides. An equilateral triangle has congruent sides, which means that each side is the same length. The triangle MDE is equilateral only because it is midpoint of ACB

If the square of the longest side is smaller than the sum of the squares of the two smaller sides, the triangle is said to have an acute angle according to Pythagoras's theorem. Given a triangle with sides "a," "b," and "c," with side "a" being the longest, the triangle is steeply angled if "a2" exceeds "b2" plus "c2."

By adding the squares of the triangle's two smaller sides and comparing the result to the square of the largest side, you may determine whether the triangle is acute, right, or obtuse. The triangle is sharp because this total is higher.

Isosceles, equilateral, or scalene acute triangles are all possible. An acute triangle's longest side is located across from its biggest angle.

We have to find her hourly overtime rate.

India is working overtime so her regular hourly rate is 1/2.

Evaluating the expression

We find her hourly overtime rate in percentage.

She receive overtime rate for 1 time is 1/2 rate.

We can write 1/2 as 0.5.

To express it as percentage we multiply and divide by 100.

Given that, an equation of the line that passes through the point (−6,−8) and is parallel to the line x−2y=6.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

We know that, the slope of a line parallel to given line is m1=m2.

Here, x−2y=6

⇒ 2y=x-6

⇒ y=x/2-3

So, slope = 1/2

The slope of a line parallel to the given line = 1/2

Now, put m=1/2 and (x, y)=(-6, -8) in y=mx+c and solve for c

-8=1/2(-6)+c
