Review the following problem and answer the questions that follow.


1) What mistake did I make?

2) What suggestion would you give me to avoid making that same mistake in the future?

Answer:

2,000,000

Step-by-step explanation:

First of all, I think that you are asking:

[tex]\sqrt{10}*\sqrt{10}*10*10\sqrt{10}*100*2\sqrt{10}[/tex]=?

So, because multiplication is commutative, we are allowed to group together what we know and what we will deal with later:

[tex]\sqrt{10}*\sqrt{10}*10*10\sqrt{10}*100*2\sqrt{10}[/tex] can be rewritten as

[tex](10*10*100*2)*\sqrt{10}* \sqrt{10}*\sqrt{10}*\sqrt{10}[/tex]

10*10*100*2=20,000

[tex]20,000(\sqrt{10}*\sqrt{10}*\sqrt{10}*\sqrt{10})[/tex]

So, what we do know is that when we take the square root of a number and multiply it by itself (or "square" it) we will get back the number that we started with.

So:

[tex]\sqrt{10}*\sqrt{10} =10[/tex]

We can rewrite what we had up top as:

[tex]20,000((\sqrt{10})*(\sqrt{10}))*((\sqrt{10})*(\sqrt{10}))[/tex]

[tex]20,000(10)(10)[/tex]

[tex]20,000(100)[/tex]

[tex]20,000(100)=2,000,000[/tex]

Answer:

27

Step-by-step explanation:

w = 6

x = 2

5w

= 5 x 6

= 30

w / x

= 6 / 2

= 3

5w - w / x

= 30 - 3

= 27

Answer:

4y - 3x = -25

Step-by-step explanation:

The equation of a line in point-slope form is expressed as

y - y0 = m(x - x0)

(x0, y0) is the point

m is the slope

Given

(x0, y0) = (3, -4)

Also given the equation;

8x + 6y = 15

Rewrite in standard form;

6y = -8x+15

y = -8/6 x + 15/6

y = -4/3 x + 5/2

Slope m = -4/3

Since the required line is perpendicular to the given line =,

Slope = -1/(-4/3) = 3/4

Substitute into the formula;

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

y + 4 = 3/4(x-3)

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

4y + 16 = 3x - 9

4y - 3x = -9-16

4y - 3x = -25

This gives the required equation

Answer:

0.05223

Step-by-step explanation:

0.05723 is 0.05223 greater than 0.005.

A decimal number is one in which the whole number component and the fractional component are separated by a decimal point. The decimal point is the dot seen in decimal numbers. The decimal point is followed by digits that represent a number less than one.

As an illustration, consider the decimal value 17.48, where 17 is the entire integer and 48 is the decimal portion.

When one number exceeds another, the phrase "more than" is used. Even greater than is utilised to compare the two weights.

Take the difference

0.05723-0.005=0.05223

Hence, 0.05723 is 0.05223 greater than 0.005.

Answer:

Step-by-step explanation:

a. The sample space for this spinner would be A, B or C . Since these are the only possible outcomes in this specific spinner.

b. The spinner has a total of 6 sections but each letter has 2 sections dedicated to it. Therefore, this makes only 3 possible outcomes in which the spinner will only land on 1. This means that the probability of each letter would be 1/3

The opposite of a function is its inverse

The ordered pairs that represent the inverse of function f(x) are (-2,4), (-2,-2), (-2,-1)

From the function, we have the following ordered pairs

(x,y) = (4,-2), (-2,-2), (-1,-2)

The inverse of a function (x,y) is (y,x).

So, we have:

(y,x) = (-2,4), (-2,-2), (-2,-1)

Hence, the ordered pairs that represent the inverse of function f(x) are (-2,4), (-2,-2), (-2,-1)

Step-by-step explanation:

2(3s + t) + 2(3s - 9t)

6s + 2t + 6s - 18t

12s + 2t - 18t

12s - 16t

Answer:Perimeter of the rectangle =(12s -16t)centimeters.

Step-by-step explanation:

The perimeter of a rectangle is given as 2(l+w)

Given that  width of the  rectangle=(3s+t)centimeters. and

Length of the  rectangle=(3s-9t)centimeters.

Solving we have

Perimeter= 2(l+w)

Perimeter=2(3s+t +3s-9t)

Perimeter=2(3s+3s -9t+t)

Perimeter=2(6s-8t)

Perimeter=(12s -16t)centimeters.

I don't know if you got this pic but this is the answer for this pic

Answer:

y = x²+8x+7

Step-by-step explanation:

according to the table, we get the point :

(-4, -9) as the vertex and (0, 7) as y-intercept

y = ax²+bx+c

=> the symetry axis :

x = -b/2a = -4

b=-4×2a = 8a

let a=1, => b = 8(1) = 8

y-intercept = (0, c) =(0, 7) => c =7

so, the equation might be :

y = x²+8x+7

Hi there! Given the equation below.

[tex] \large{r + \sqrt{x} = 9}[/tex]

First is to subtract both sides by r-term to isolate x-term.

[tex] \large{r + \sqrt{x} - r = 9 - r} \\ \large{ \sqrt{x} = 9 - r}[/tex]

Because the x-term is in square root form. We have to square both sides to get rid of the square root.

[tex] \large{( \sqrt{x})^{2} = {(9 - r)}^{2} } \\ \large{x = {(9 - r)}^{2} }[/tex]

Alternative Solution

Answer:

P(black): 4/9

P(yellow): 2/9

P(orange): 3/9

Step-by-step explanation:

There are 4 black cubes, 2 yellow cubes, and 3 orange cubes. Add all of the cubes together to know how many cubes there are total.

4+2+3 = 9

Now that you know there are 9 cubes, you see how many black cubes you can draw out of 9. You can draw 4 black cubes out of the 9 total cubes, so the probability is 4/9.

You see how many yellow cubes you can draw out of 9. You can draw 2 yellow cubes out of the 9 total cubes, so the probability is 2/9.

You see how many orange cubes you can draw out of 9. You can draw 3 orange cubes out of the 9 total cubes, so the probability is 3/9.

Answer:

x = [tex]\frac{83}{36}[/tex]

Step-by-step explanation:

Given

x - 2 [tex]\frac{1}{4}[/tex] = [tex]\frac{1}{18}[/tex] ( change mixed number to improper fraction )

x - [tex]\frac{9}{4}[/tex] = [tex]\frac{1}{18}[/tex]

Multiply through by 36 ( the LCM of 4 and 18 ) to clear the fractions

36x - 81 = 2 ( add 81 to both sides )

36x = 83 ( divide both sides by 36 )

x = [tex]\frac{83}{36}[/tex]

Answer:

Step-by-step explanation:

This factors using a perfect square trinomial. You can recognize this by several characteristics. First off, the leading coefficient is a perfect square (25); second, the constant is also a perfect square (4). Third, the second sign is a + which means that both the signs inside the parenthesis are the same and they are both whatever the first sign is, - . Factoring this then, is the (square root of the leading coefficient times x - square root of the constant):
