Answer:

6 floors per 1 minute

2 and a half pancakes per minute

etc.

Step-by-step explanation:

Simplify to the ratios lowest form and the compare.

Step-by-step explanation:

If the price increases 3/4 per share, the new price of the stock =

6¾ + ¾ =

27 /4 + ¾ =

30 /4 =

15/2 or 7½

The new price of the stock which increases 3/4 per share is $ 7 1/2.

Given data:

A stock is selling on a stock exchange for 6 3/4 dollars per share.

If the price of the stock increases by 3/4 dollars per share, you can add 3/4 to the current price of 6 3/4 dollars per share:

6 3/4 + 3/4

To add the whole numbers and fractions separately:

6 + 0 + 3/4 + 3/4

Adding the whole numbers and fractions:

6 + 1 1/2

A = 7 1/2

Hence, the price of the new stock is $ 7 1/2

Pulling out like terms

3.1     Pull out like factors :

  8x2 - 8  =   8 • (x2 - 1)  

Trying to factor as a Difference of Squares:

3.2      Factoring:  x2 - 1  

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check : 1 is the square of 1

Check :  x2  is the square of  x1  

Factorization is :       (x + 1)  •  (x - 1)

Theory - Roots of a product

4.1    A product of several terms equals zero.  

When a product of two or more terms equals zero, then at least one of the terms must be zero.  

We shall now solve each term = 0 separately  

In other words, we are going to solve as many equations as there are terms in the product  

Any solution of term = 0 solves product = 0 as well.

Equations which are never true:

4.2      Solve :    8   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

4.3      Solve  :    x+1 = 0  

Subtract  1  from both sides of the equation :  

                     x = -1

Solving a Single Variable Equation:

4.4      Solve  :    x-1 = 0  

Add  1  to both sides of the equation :  

                     x = 1

Two solutions were found :

Using the Empirical Rule and z-scores, we have that:

a) 95% of individuals who sleep between 4.9 and 9.7 hours per day.

b) Z = 0.58.

c) Z = -1.08.

It states that, for a normally distributed random variable:

In item 2, both 4.9 and 9.7 are 2.4 hours from the mean, that is, 2 standard deviations, hence 95% of individuals who sleep between 4.9 and 9.7 hours per day.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

For this problem, the mean and the standard deviation are given as follows:

[tex]\mu = 7.3, \sigma = 1.2[/tex]

The z-score for an adult who sleeps 8 hours per night is:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (8 - 7.3)/1.2

Z = 0.58.

The z-score for an adult who sleeps 6 hours per night is:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Z = (6 - 7.3)/1.2

Z = -1.08.

-3x + 50 = 101

       -50   -50      subtract 50 from both sides, 50's cancel out from the left.

___________     solve for 101 - 50.

-3x = 51

___  ___              divide -3 on both sides, -3's cancel out on the left.

-3     -3                 solve for 51 ÷ -3.

At Cowtown Bowling Center, we can do the same thing. The cost of shoes + the cost of a game= $6.50. If we add the cost of a game two more times, we get $14.50.

The function has a maximum of 2 at [tex]x=1[/tex]

Step-by-step explanation:

The graph is a vertical parabola. The minimum, or min is when the parabola opens up, the vertex is at the lowest point on the graph. The maximum, or maxis when the parabola opens down, the vertex is the highest point on the graph.

Since it asks for "[tex]x[/tex]", we can tell that it is 1. If you look at the x-axis in the graph at where the point lies, you will find that [tex]x=1[/tex]

113.1

Step-by-step explanation:

With this picture, I'm assuming that the diameter of the circle is 12m

If this is the case, the radius is equal to 12/2 = 6

Area = pi*r^2 = pi*36 = 113.1 (rounded to the nearest tenth)

Answer:

113.1 m²

Step-by-step explanation:

Diameter = 12m

Radius = Diameter/2 = 12/2 = 6

A=πr^2 = π·6^2 = 113.09734 m²

Rounded to the nearest tenth = 113.1 m²
