Is 8.78778777
a rational or irrational number?

Answer:

11

Explanation:

Because 57 minus 2 games already equals 55, so 55 games divided by 5 months equals 11, so 11 games each month will get u to 57.

The number of games must his team win per month will be;

⇒ x > 11

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

Steve Conway wants his team to win more than 57 games this year.

And, His team has already won 2 games this season and there are 5 more months to play.

Now,

Let number of games must his team win per month = x

So, We can formulate the inequality as;

⇒ 5x + 2 > 57

Solve for x as;

⇒ 5x > 57 - 2

⇒ 5x > 55

⇒ x > 11

Thus, The number of games must his team win per month will be;

⇒ x > 11

Answer:

x = 30

Step-by-step explanation:

5/6x- 1/5x =19

Get a common denominator of 30

5/6x * 5/5  - 1/5x * 6/6 = 19

25/30x - 6/30x = 19

19/30x = 19

Multiply each side by 30/19

19/30x * 30/19  = 30/19 * 19

x = 30

Answer:

5/6x- 1/5x =19

5/6x- 1/5x =19

?/30x=19

19/30x = 19

x = 19 / 19/30

x = 19 * 30/19

x = 30

Slope is 1.5

Y intercept is (0,1) A

Equation y = (3x/2) + 1 = 1.5x + 1A

What does it mean by another solution?

If it means the other way to do slope (y=mx+b)

b=4−(3/2) * 2 = 1

The answer is still y=(3x/2)+1

Answer:

250x^3 - 500x^3i

Step-by-step explanation:

We have a = 5x

b = 2 - 4i

Now,

= a^3b

= (5x)^3(2 - 4i)

= 125x^3 (2 - 4i)

= 250x^3 - 500x^3i

When the shadow is 45 meters long, it should be noted that the height of the utility pole will be 24 meters.

It should be noted that from the information, Antonio knows that a antenna that is 16 meters tall casts a shadow that is 30 meters long and he wants to calculate the height of a nearby pole.

Let the height be x.

Therefore, this will be illustrated as:

16 / 30 = x / 45

Cross multiply.

30 × x = 45 × 16

x = (45 × 16) / 30

= 24

Therefore, when the shadow is 45 meters long, it should be noted that the height of the utility pole will be 24 meters.

Answer:

  Change on Day 1 = 29.80 °C

  Change on Day 2= 30.60 °C

  the most change occurred on Day 2

Step-by-step explanation:

Given a table of days and temperatures, you are asked for the changes each day, and you are asked which day changed the most.

In general, the change in an amount is the difference between the final amount and the beginning amount. Here we have temperatures at the beginning of the day and the end of the day. We presume the change of interest is the difference between the temperature at the end of the day and that at the beginning.

  end of day temp - beginning temp = 18.74 -(-11.06) = 29.80 . . . °C

  end of day temp - beginning temp = 21.29 -(-9.31) = 30.60 . . . °C

The day 2 change is larger than the day 1 change, so the most change occurred on day 2.

  Radical already isolated

    √163 = x

Raise both sides to the second power

    (√163)2 = (x)2

    After squaring

    163 = x2  Rearranged equation

    x2  -163 = 0

    This equation has two real roots:

      x1 = ( 0 + sqrt(652) ) / 2 = 12.7671

     x2 = ( 0 - sqrt(652) ) / 2 = -12.7671  Original equation

    √163 = x

    Plug in 12.7671 for  x  

     √163 = (12.7671)

     Simplify

     √163 = 12.767

x=5.6

Step-by-step explanation:

The equation is

2/1.6=7/x

1.25=7/x

1.25x=7

x=7/1.25

x=5.6

Answer:

Step-by-step explanation:

We will use a proportion to solve this. All we need are two corresponding values. One is x and 7, we'll pick the other as 32 and 4.

Now, we'll set up the proportion

[tex]\frac{x}{7} = \frac{32}{4}[/tex]

To solve a proportion, we cross multiply the means and extremes.

4x = 32 x 7

4x = 224

x = 56

We can check the proportion by substituting our answer in for x and seeing if the products equal. If they do, we know we have the correct answer.

4(56) = 32 x 7

224 = 224 ✅

Answer:

9.25×10^7

Step-by-step explanation:

2.5 × 3.7 =9.25 and 10^2+10^5=10^7

The final expression after simplifying

[tex](-y^2-3y-5) - (3y^2-7y+4)-(2y^2+4y-9)-(2y^2-10y+4)-(2y^2-7y-9)-(-2y^2-10y-1)[/tex]

is [tex]\bold{-8y^2+27y+6}[/tex].

The given expression is

[tex](-y^2-3y-5) - (3y^2-7y+4)-(2y^2+4y-9)-(2y^2-10y+4)-(2y^2-7y-9)-(-2y^2-10y-1)[/tex]

We will solve this step-by-step. Also remember that (a -b) = -(b -a), when

a < b and -a-b = -(a + b)

So first solving by subtraction,[tex](-y^2-3y-5)-(3y^2-7y+4)=-y^2-3y-5-3y^2+7y-4= -4y^2 +4y-9[/tex]

Next, [tex]-4y^2+4y-9 -(2y^2+4y-9)=-4y^2+4y-9-2y^2-4y+9=-6y^2[/tex]

i.e., [tex]-6y^2-(2y^2-10y+4) = -8y^2+10y-4[/tex]

which gives, [tex]-8y^2+10y-4-(2y^2-7y-9)=-10y^2+17y+5[/tex]

And finally,[tex]-10y^2+17y+5-(-2y^2-10y-1)=\bold{-8y^2+27y+6}[/tex]
