Answer:

[tex]\frac{901}{999}[/tex]

Step-by-step explanation:

we know that

A Recurring Decimal, is a decimal number with a digit (or group of digits) that repeats forever.

In this problem we have

0.901 recurring

that means

0.901901901..

Let

[tex]x=0.901901901..[/tex]

Multiply x by a power of  [tex]10[/tex], one that keeps the decimal part of the number the same:  

[tex]1,000x=901.901901..[/tex]

Subtract [tex]x[/tex] from [tex]\\1000x[/tex]

[tex]1,000x-x=901.901901..-0.901901..=901[/tex]

The repeating decimals should cancel out

[tex]\\999x=901[/tex]

solve for x

Divide by [tex]999[/tex] both sides

[tex]990x/990=135/990[/tex]

[tex]x=\frac{901}{999}[/tex]

Answer:

The slope is 0. However, it is a horizontal line where x=-6.

Step-by-step explanation:

Use the equation m= y2-y1/x2-x1 to get 12--8/-6--6. Two negatives means a positive, so you get 20/0. This means there is no slope, because you cannot divide by 0. However, you notice that both x-values are -6, so you can safely assume that there is a horizontal line where x=-6.

The slope is undefined and the line is vertical and parallel to the y-axis.

Given points (-6, -8) and (-6, 12)

First, the slope of line is

Slope= (change in y/ change in x

         = (12 - (-8)) / (-6 - (-6))

         = (12 +8) / (-6 +6)

         = 20 /0

         = ∞

Since we have a division by zero in the denominator, the slope is undefined.

This indicates that the line is vertical and parallel to the y-axis.

Thus, the slope is undefined.

Answer:

The answer would be m= -9

Step-by-step explanation:

6(9-m)

You will multiply the 6 with the 9 and -m inside of the parenthesis

54-6m

Divide by -6 on both sides and you will get m= -9

I hope this helps you with this question and have a nice weekend

The equivalent expression to 6(9 - m) is 54 - 6m, determined by applying the distributive property of multiplication over addition and subtraction.

The expression given is 6(9 - m). To identify an expression equal to this, we should look for expressions that maintain the same relationship between the numbers and the variable m. When we distribute the 6 across the parentheses, we multiply 6 by 9, and 6 by -m, resulting in 54 - 6m.

Distributing a number across a subtraction in a parenthesis follows the distributive property of multiplication over addition and subtraction, which allows us to multiply each term inside the parentheses by the number outside.

Answer: Second Option

20%

Step-by-step explanation:

We have 5 red marbles, 8 blue marbles and 12 green marbles in a bag.

In total there are 5 + 8 + 12 = 25 marbles

This means that the experiment "get a marble out of the bag" has 25 possibilities.

Then, the chances of getting a red marble are 5, because there are 5 red marbles.

Finally the probability of drawing a red marble is:

[tex]P_{red} = \frac{5}{25}\\\\P_{red} = \frac{1}{5}\\\\P_{red} = 0.20[/tex]

[tex]P_{red} =20\%[/tex]

Answer:

The answer is 7/8 chance.

Step-by-step explanation:

To find this answer, you have to divide the blue marbles by red marbles. Then, you will get 28/32.

You can simplify it, so simplify it to the smallest possible number, therefore getting 7/8.

8 times 2/3 is 16/3, which when simplified is 5 1/3

To evaluate 8(2/3), you need to multiply 8 by 2/3. The value of 8(2/3) is 16/3.

To evaluate 8(2/3), you need to multiply 8 by 2/3. To do this, you can simplify 2/3 by dividing both the numerator and denominator by their greatest common factor, which is 1.

This simplifies 2/3 to 2/3. Then, multiply 8 by 2/3 to get the final answer.

Therefore, the value of 8(2/3) is 16/3.

B.. skewed left

Step-by-step explanation:

Answer:

Option B. skewed left.

Step-by-step explanation:

In the figure attached maximum frequency of the data is at the 45. Distribution on the right side of the maximum frequency is upto 48 and in the left it is upto 36.

As we can see point 36 is more distant from peak point 45 as compared to point 48.

Therefore, distribution of the data is more in the left than in the right.

Therefore, the shape of this distribution is skewed left.

Option B. skewed left is the correct answer.

Divide bags of sand by gallons of water:

14 /6 = 2.33

21/9 = 2.33

The ratio is the same, so this means for every gallon of water you need 2.33 bags of sand.

Convert the fractions into decimals and you will get 7/3 = 2.33

The answer for Part 1 is D) 7/3

For part 2, multiply the gallons of water by 2.33 to get the number of sand bags needed:

12 x 2.33 = 27.99, which rounds to 28.

The answer is C) 28 bags.

Answer:

A) [tex]\frac{3}{7}[/tex]

C) 28 bags

Step-by-step explanation:

Part 1 :

By the given table,

[tex]\frac{\text{Gallon of water}}{\text{bags of sand}}=\frac{6}{14}=\frac{9}{21}=\frac{15}{35}=\frac{3}{7}[/tex]

Hence, the proportion of gallons of water to bags of sand is same,

Which is [tex]\frac{3}{7}[/tex]

OPTION A) is correct.

Part 2 : Let x bags of sand should be mixed with 12 gallon of water,

Then the ratio of gallon of water and number of bags of sand = [tex]\frac{12}{x}[/tex]

By part 1,

[tex]\frac{12}{x}=\frac{3}{7}[/tex]

[tex]84 = 3x[/tex] ( by cross multiplication )

[tex]\implies x = \frac{84}{3}=28[/tex]

Hence, 28 bags of sand should be mixed.

OPTION C) is correct.

2x = 24 ( divide both sides by 2 )

x = 12

Answer:

2541 peanut cookies were sold

Step-by-step explanation:

A system of equations can be written to match the problem description. Let p and c represent the initial numbers of peanut and chocolate cookies, respectively. Then we have ...

p - c = 1820 . . . . Lyn had 1820 more peanut cookies

After selling 35% of her peanut cookies, Lyn had 1-0.35 = 0.65 of the original number left. Likewise, after selling 15% of her chocolate cookies, she had 1-0.15 = 0.85 of the original number left. Then after the sales, the difference in cookie count was 95:

0.65p -0.85c = 95

We only need to know the original number of peanut cookies (p), so we can use Cramer's rule to find the solution for p.

p = (-95 +0.85·1820)/(-0.65+0.85) = 1452/0.20 = 7260

The original number of peanut cookies Lyn had was 7260, so the number she sold is ...

0.35 · 7260 = 2541

Answer:  D. 2x4+x3–x+2 is prime

Step-by-step explanation:

Given the point (9,2) is on the graph of f(x), the corresponding point for the function f(-3/4x) is found by multiplying the x-coordinate of the given point by -3/4. This yields the corresponding point (-6.75, 2).

The given point is (9,2). In the function f(-3/4x), the variable is multiplied by the factor -3/4. We apply this factor to the x-coordinate of the given point to find the x-coordinate of the corresponding point in the function f(-3/4x).

Therefore, the x-coordinate of the corresponding point is 9×-3/4 = -27/4 = -6.75. The y-coordinate remains the same because the transformation corresponds only to the x-coordinates of points. So, the corresponding point in the function f(-3/4x) is (-6.75,2).
