Answer:

1999 The most points scored in an NHL career is 2,857, achieved by Wayne Gretzky (Canada) while playing for the Edmonton Oilers (Canada), Los Angeles Kings, St Louis Blues and New York Rangers (all USA) from 1979 to 1999. The points total comprises 894 goals and 1,963 assists in 1,487 games.

Step-by-step explanation:

a) Wayne Gretzky's average points per game is approximately 1.9202.

b) Wayne Gretzky would have scored approximately 151.5438 more points if he had played 79 more games.

a) To calculate Wayne Gretzky's average points per game, we divide the total points scored (2857) by the total number of games played (1487):

Average points per game = Total points scored / Total games played

Average points per game = 2857 / 1487 ≈ 1.9202

Wayne Gretzky's average points per game is approximately 1.9202.

b) To find out how many more points Wayne Gretzky would have scored if he had played 79 more games, we can use the average points per game calculated in part (a).

We know that his average points per game is approximately 1.9202. So, to find the additional points in 79 games, we can multiply the average points per game by the number of additional games:

Additional points = Average points per game * Additional games

Additional points = 1.9202 * 79 ≈ 151.5438

Wayne Gretzky would have scored approximately 151.5438 more points if he had played 79 more games.

Answer:

x=20  and  x=-50

Step-by-step explanation:

To find the roots, we need to simply solve for x. We do this by first moving all of the terms to the left and setting the right side equal to 0.

-1000

x^2+30x-1000=0

Now, factor it.

What adds up to 30 but multiplies to get -1000?

-10 and 40? No, because they multiply to get -400.

-20 and 50? Yes, because they add up to 30 and multiply to get -1000.

(x-20)(x+50)

x-20=0

x=20

x+50=0

x=-50

So, the roots are x=20 and x=-50

Given :-

To Find :-

Solution :-

As we know that if the quadratic equation is in standard form which is ,

[tex] ax^2+bx + c =0[/tex]

Then its roots are given by ,

[tex] x =\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

So on converting the equation in standard form ,

[tex] x^2+30x -1000=0[/tex]

With respect to the standard form ,

Substitute in the Quadratic formula ,

[tex] x =\dfrac{-30\pm \sqrt{(30)^2-4(1)(-1000)}}{2(1)}[/tex]

Simplify,

[tex] x =\dfrac{-30\pm\sqrt{900+4000}}{2}[/tex]

Add the numbers inside square root ,

[tex] x =\dfrac{-30\pm\sqrt{4900}}{2}[/tex]

Divide each term in numerator by 2,

[tex] x =\dfrac{-30}{2}\pm\dfrac{\sqrt{70^2}}{2}[/tex]

Simplify ,

[tex] x = -15 \pm 35 [/tex]

Separate the two solutions ,

[tex] x = -15 + 35 , -15 -35[/tex]

Simplify ,

[tex]x = 20 , -50 [/tex]

Hence the solution of the equation are 20 and -50 .

Answer:

225,000 (selling price) 75,000 (profit)

Step-by-step explanation:

x = (150,000 ÷ 2) x 3

x = 75,000 x 3

x = 225,000

225,000 (sell) - 150,000 (cost)

= 75,000 (profit)

Answer: I GOT YOU

Step-by-step explanation: The poster says, "Open an account of ​$3,500 and earn at least ​$10 interest in 1​ month!" is correct

He decides to make a poster advertising a simple interest rate of 4.8%.  

We have to find what must the principal be if the bank manager also wants to advertise that one can earn  $10 the first month

So, the statement is correct.

Hence, the amount to be invested is $2500 and the poster says correctly.

answer:

(x,y)=( -4, -3)

Answer:

{x,y}={-4,-3}

Step-by-step explanation:

// Solve equation [1] for the variable  y

 [1]    y = 2x + 5

// Plug this in for variable  y  in equation [2]

  [2]    -4x + 3•(2x+5) = 7

  [2]    2x = -8

// Solve equation [2] for the variable  x

  [2]    2x = - 8

  [2]    x = - 4

// By now we know this much :

   x = -4

   y = 2x+5

// Use the  x  value to solve for  y

   y = 2(-4)+5 = -3

Solution :

{x,y} = {-4,-3}

Answer:

[tex]-1\frac{7}{9}[/tex]

Step-by-step explanation:

Rewriting our equation with parts separated

[tex]2+\frac{8}{9} -4+\frac{2}{3}[/tex]

Solving the whole number parts

[tex]2-4=-2[/tex]

Solving the fraction parts

[tex]\frac{8}{9} -\frac{2}{3} =?[/tex]

Find the LCD of 8/9 and 2/3 and rewrite to solve with the equivalent fractions.

LCD = 9

[tex]\frac{8}{9} -\frac{6}{9} =\frac{2}{9}[/tex]

Combining the whole and fraction parts

[tex]-2+\frac{2}{9} =-1\frac{7}{9}[/tex]

Hence, -1 7/9 is the correct Answer.

Step-by-step explanation:

it is the area of the square minus 4 quarter circles (which means 1 full circle) with radius of 10 ft (the half of a side of the square).

we know how to calculate the area of a square "As"

As = side²

we know how to calculate the area of a circle "Ac"

Ac = pi×radius²

so, the shaded area "Ashade"

Ashade = side² - pi×radius² = 20² - pi×10² =

= 400 - pi×100 = 85.84073464... ft²

I don't know, if you need to round the answer in some way.

if it is to e.g. 2 digits after the decimal point (hundredths), then it would be

5/8+2/8+7/8 = 5+2+7/8 = 14/8 = 1 6/8 = 1 3/4 or 1.75

Answer: 1 3/4 or 1.75

Step-by-step explanation:

Answer:

Matter of deleting not useful facts and using what we know and need.

Mrs.Chau.ke is 66 years old is not useful since this age doesn’t ask for age or the effect of age.

Earns 180 per hour and works 8 hours a day is useless since we’re already given the monthly income.

The monthly income 32040 is the most important here since we need to find the ANNUAL income which means yearly.

32040 per month * 12 months is 384480

384480 is the annual income

Mrs. Chauke's annual income if she earns R32 040 per month is

R384 480​

The given parameters are:

Hourly rate = R180

Work time = 8 hours a day

Monthly income = R32040

There are 12 months in a year.

So, the annual income is:

Annual = 32040 * 12

This gives

Annual = 384480

Hence, Mrs. Chauke's annual income if she earns R32 040 per month is

R384 480​

Step-by-step explanation:

m<FDE = 45° (alternate angles)

w = 70° (corresponding angles)

x = 42° (atlernate angles)

x + z = 180° (linear pairs)

or, z = 180° - 42°

I do not agree with the solutions, b=-30, reasoning below.

Step-by-step explanation:

Mai made an error between the first and second line, she added one to the right when she should have subtracted one:

2/5b+1=-11

2/5b=-12

She then multiplied by 5/2 which was correct, however she multiplied it by -10 when it should have been -12:

b=-12*5/2

b=-30

Tyler made an error between the first and second line when he did not multiply the 1 on the left by 5 also:

2/5b+1=-11

2b+5=-55

He did the next steps correctly, however he had the incorrect value, it should look like this:

2b=-60

b=-30

Step-by-step explanation:

Squaring the given equation gives

[tex]t^2+(2\cdot t \cdot \frac{1}{t} )+ \frac{1}{t^2}=9.[/tex]

The [tex]t[/tex] and [tex]\frac{1}{t}[/tex] terms cancel out nicely, which is one of the reasons for squaring the equation.

Simplifying gives

[tex]t^2+2+\frac{1}{t^2}=9,[/tex]

[tex]t^2+\frac{1}{t^2}=7.[/tex]

The question asks for [tex]t^5+\frac{1}{t^5},[/tex] so we can square the equation again and simplify to get higher powers into the expression:

[tex](t^2+\frac{1}{t^2})^2=49,[/tex]

[tex]t^4+(2 \cdot t^2 \cdot \frac{1}{t^2}) + \frac{1}{t^4}=49,[/tex]

[tex]t^4+2+ \frac{1}{t^4}=49,[/tex]

[tex]t^4+\frac{1}{t^4}=47.[/tex]

Multiplying this expression by [tex]t+\frac{1}{t}[/tex] to try and get a fifth power gives

[tex](t^4+\frac{1}{t^4})(t+\frac{1}{t})=t^5+t^3+\frac{1}{t^3}+\frac{1}{t^5}.[/tex]

The only thing left we need is [tex]t^3+\frac{1}{t^3}[/tex] to subtract from this; we know everything else. Since [tex]t^3+\frac{1}{t^3}[/tex] can be written as [tex](t+\frac{1}{t})(t^2-1+\frac{1}{t^2}),[/tex] we can simply plug in the values we know for [tex]t+\frac{1}{t}[/tex] and [tex]t^2+\frac{1}{t^2}:[/tex]

[tex]t^3+\frac{1}{t^3}=(3)(7-1)=18.[/tex]

All that is left is to plug it in our equation here:

[tex](t^4+\frac{1}{t^4})(t+\frac{1}{t})=t^5+t^3+\frac{1}{t^3}+\frac{1}{t^5},[/tex]

[tex](47)(3)=t^5+\frac{1}{t^5}+18,[/tex]

Multiplying and rearranging gives:

[tex]t^5+\frac{1}{t^5}=123.[/tex]

The statement that must be true about the two similar triangles based on the triangle similarity theorem is: option 2 and option 3.

The triangle similarity theorem states when a segment intersects the other two sides of a triangle, and the segment is parallel to the third side, then the two triangles formed are similar, and the corresponding sides are proportional to each other.

Given that line segment BD is parallel to line segment AE, therefore, triangles CBD and CAE are similar triangles, their corresponding angles are congruent, while their corresponding sides are proportional.

Therefore, the statement that must be true about the two similar triangles based on the triangle similarity theorem is: option 2 and option 3.
