Answer:

Answer to 6/9-2/3= 0; Lowest common denominator = 3;

Step-by-step explanation:

You can only reduce 6/9 to 2/3, you cant reduce the fraction any further.

The resultant of subtraction of both vectors is

|r - s| = √(r² + s² - 2rscos{15})

A vector is an object that has both a magnitude and a direction.

Given is that |r| = 6 at an angle of 30° and |s| = 11 at an angle of 225°.

For the subtraction of vectors, we can write its magnitude as -

|r - s| = √(r² + s² - 2rscos{15})

Therefore, the resultant of subtraction of both vectors is

|r - s| = √(r² + s² - 2rscos{15})

A line that shows the number of hair barrettes she makes and the total number of beads she uses is y = 75x.

In order to put the equation in y-intercept (y=mx+b) form and determine the equation of a graphed line, you must first determine the slope and y-intercept. The slope is the ratio of the change in y to the change in x. Find two locations on the line, and then draw a sloping triangle joining them.

A line is a perfectly straight, one-dimensional figure that extends infinity in both directions and has no thickness. To stress that a line has no "wiggles" anywhere along its length, it is sometimes referred to as a straight line or, more archaically, a right line.

Two points on the line are (2, 150) and (5, 375)

y - 150 = ( (375-150) / (5-2) )  (x-2)

y - 150 = 75 (x-2)

y = 75x

Equation of line is y = 75x

On solving the provided question we can say that - the increased value in fraction will be [tex]3\frac{1}{4}[/tex]

Any number of equal portions, or fractions, can be used to represent a whole. Fractions in standard English indicate how many units of a certain size there are. 8, 3/4. A whole includes fractions. The ratio of the numerator to the denominator is how numbers are expressed in mathematics. Each of these is an integer in simple fractions. In the numerator or denominator of a complex fraction is a fraction. True fractions have numerators that are less than their denominators. A fraction is a sum that constitutes a portion of a total. By breaking the entire up into smaller bits, you can evaluate it. Half of a full number or item, for instance, is represented as 12.

Step-by-step explanation:

Answer: Her total earnings would be $28+$54=$82.

Step-by-step explanation:

Lori's base salary is calculated by multiplying her hourly rate by the number of hours she works. If Lori works 4 hours on a Tuesday and earns $7/hr, her base salary would be 4*$7=$28.

Lori's tips are calculated as 18% of her food sales. If Lori has $300 of food sales on a Tuesday, her tips would be 18%*$300=$54.

Lori's total earnings for the day would be the sum of her base salary and her tips. In this case, her total earnings would be $28+$54=$82.

1. The vertex of am angle is formed when two lines join together. The vertex of the angle shown in the diagram is located outside the circle.(<R)

2. The lines that created <FRT (lines FR & TR) are secants

3. The major arc = FT = 140°

minor arc = QS = 44°

4. Formula of Exterior angles of a circle = (major arc - minor arc)/2

x = (140 - 44)/2

x = 96/2

x = 48°

Answer:

7

Step-by-step explanation:

The required probabilities are
• Exactly 2 are male = 0.08

• At least 7 are male = 0.14

• None are male = 0.60

• Less than 3 are male = 0.12

• There are 3 or 4 males = 0.019

• At least 1 is male = 0.04

Probabilities to college reported that 40% of its population is male. Nine students are selected at random.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

For Exactly 2 are male = 2 * 0.04
                                       = 0.08
Similarly,
• At least 7 are male = 0.14

• None are male = 1 -0.40 = 0.60

• Less than 3 are male = 0.12

• There are 3 or 4 males = 0.12 *0.16 = 0.019

• At least 1 is male = 0.04

Thus, the required probability is given above.

The combined mass of the compounds is 13/12 grams

From the question, we have the following parameters that can be used in our computation:

3/4 gram sodium chloride and 1/3 gram potassium chloride

The combined mass of the compounds is then calculated as

Combined mass = sodium chloride + potassium chloride

Substitute the known values in the above equation, so, we have the following representation

Combined mass = 3/4 + 1/3

Evaluate the sum

Combined mass = 13/12

Hence, the combines mass is 13/12 grams

Answer:

They are not inverse functions

Step-by-step explanation:

Given

[tex]f(x) = 5x[/tex]

[tex]f^{-1}(x) = x[/tex]

Required

Determine if both are inverse functions

First calculate the inverse of f(x)

[tex]f(x) = 5x[/tex]

Replace f(x) with y

[tex]y = 5x[/tex]

Swap x and y

[tex]x = 5y[/tex]

Make y the subject

[tex]y = \frac{1}{5}x[/tex]

Replace y with f-1(x)

[tex]f^{-1}(x) = \frac{1}{5}x[/tex]

By comparison:

[tex]f^{-1}(x) = x[/tex] and [tex]f^{-1}(x) = \frac{1}{5}x[/tex] are not the same:

Hence:

[tex]f(x) = 5x[/tex] and [tex]f^{-1}(x) = x[/tex] are not inverse functions
