Answer:

[tex]D = 1 - \frac{1}{4}[/tex]

[tex]D = \frac{3}{4}[/tex]

Step-by-step explanation:

Given:

1 bag of potting soil

[tex]Peat Moss = \frac{1}{4}[/tex]

Required

What part is dirt?

The whole bag of potting soil is represented as 1;

Let P represent Peat Moss and D represented Dirt; Such that

[tex]P + D = 1[/tex]

Subtract P from both sides

[tex]P - P + D = 1 - P[/tex]

[tex]D = 1 - P[/tex]

Substitute [tex]\frac{1}{4}[/tex] for P

[tex]D = 1 - \frac{1}{4}[/tex]

Take LCM

[tex]D = \frac{4-1}{4}[/tex]

[tex]D = \frac{3}{4}[/tex]

Hence, [tex]1 - \frac{1}{4}[/tex] or [tex]\frac{3}{4}[/tex] of the potting soil is Dirt

We want to compare averages.  From the histogram we have we don't know the exact mean, but if we just assume the average in each bin is the midpoint of the bin we can make an estimate.

Supplier A has

mean = ( 22(64) + 27(66) + 26(68) + 15(70) + 10(72) )/(22+27+26+15+10)

mean = 6728/100 = 67.28 grams

Supplier B has mean 66.5

Answer:

[tex]0.22[/tex]

Step-by-step explanation:

[tex]0.22 =22/100[/tex]

0.22 can be expressed as a fraction. Therefore, it is a rational number.

1/3 is a raional number.

[tex]1/3+22/100=83/150[/tex]

To produce a rational number we add 0.22 to 1/3. So, option C. is the right option.

A rational number is any number of the form p/q, where p, q ∈ Z, q ≠ 0, and p and q have no common factors except 1.

Any number which cannot be expressed in the above form is called an irrational number.

In the question, we are asked to find the number from the given choices, which when added to 1/3, produces a rational number.

We know that adding an irrational number to any number gives an irrational number only. So we simply need to check for the rational number among the given options. Analyzing the options:

∴ We will add 0.22 to 1/3, to produce a rational number. Option C. is the right choice.

Answer:

3 chairs

Step-by-step explanation:

1/2 is the same as 3/6

There are three 1/6 in 3/6.

(3/6) ÷ (1/6) = 3

The requried, she painted 3 chairs as of the given proportion.

Proportionality is the relationship between two or more sets of values, and it describes how these values are related to each other.

Here,
Let's assume that the number of chairs she painted is represented by the variable 'c'.

We know that she used 1/6 of a can of paint for each chair. So, the total amount of paint used for all the chairs can be expressed as:

1/6 x c = c/6

We also know that she used 1/2 of a can of paint in total. So we can set up the equation:

c/6 = 1/2

To solve for 'c', we can multiply both sides of the equation by 6:

c = 3

Therefore, she painted 3 chairs.

The points (2, -5) when reflected across the origin becomes (-2, 5)

Reflection is a mathematical transformation of a shape by moving the vertices of the shape a distance equal to the distance between the line of reflection and the original point.

Other types of transformational processes are: Rotation and translation.

Analysis:

In transformation in the origin, the line of reflection is x = 0 and y = 0.

Which means both coordinates of the point would be changed.

At x = 2, 2 is 2 units from the origin. The only point which is 2 units away from the origin in the opposite side is -2.

Also at x = -5, that is 5 units away from the origin. The only point 5 units away from the origin is 5. so the new coordinate is 5.

In conclusion, the new point after reflection would be (-2, 5)

Answer:

85

Step-by-step explanation:

The discount is original price times the percent off

The sale price is the original price minus the discount

original price - original price * 20 % = 68

Factor out the original price and change the percent to a decimal

original price ( 1 - .20) = 68

original price ( .80) = 68

Divide each side by .80

original price = 68/.80

original price = 85

Answer:

$13.60

Step-by-step explanation:

($68 x 20%) / 100

1360 / 100 = 13.6

The expression for the statement given can be written as 2 + 6n. The correct option is (B).  

An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.

The variable part of an algebraic expression can never be added or subtracted from the constant part.

Suppose the required number be n.

Then, the expression for the statement can be written as follows,

Add 2 to the product of n and 6 to obtain,

2 + 6n

Step-by-step explanation:

since a straight line is equal to 180 degrees line LN is 180 degrees therefore to figure x you must subtract 41 from 180 to get 139 hope this helps! :)

Answer:

z = 139°

Step-by-step explanation:

LON is a straight angle (an angle with 180°). You can tell just by looking at it.

41° is a supplement (meaning it adds up to 180°) of z.

From there you can just do

180° - 41° = 139°

D = 32

Step-by-step explanation:

A+ B + E = 180 since they form a triangle

14+ 45 + E = 180

E = 180 -14-45

E =121

E on either triangle is the same since they are vertical angles

C+D+E = 180 since they form a triangle

27+ D + 121 = 180

D = 180-121-27

The square root of a number is an element that can replicate itself to find that number. The square root symbol is \ sqrt {} square root of, end square root. Finding the square root of a number is the opposite of multiplying a number.

The square root of a number is a number that, when multiplied by itself, is equal to the required value. So, for example, the square root of 49 is 7 (7x7 = 49). The process of multiplying a number itself is called squaring.
