Calculating Multipliers :

3.2    Calculate multipliers for the two fractions

   Denote the Least Common Multiple by  L.C.M

   Denote the Left Multiplier by  Left_M

   Denote the Right Multiplier by  Right_M

   Denote the Left Deniminator by  L_Deno

   Denote the Right Multiplier by  R_Deno

  Left_M = L.C.M / L_Deno = x

  Right_M = L.C.M / R_Deno = 7

Making Equivalent Fractions :

3.3      Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example :  1/2   and  2/4  are equivalent,  y/(y+1)2   and  (y2+y)/(y+1)3  are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

  L. Mult. • L. Num.      4 • x

  ——————————————————  =   —————

        L.C.M              7x  

  R. Mult. • R. Num.      40 • 7

  ——————————————————  =   ——————

        L.C.M               7x  

Adding fractions that have a common denominator :

3.4       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

When a fraction equals zero :

5.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 4•(x-70)

 ———————— • 7x = 0 • 7x

    7x  

Now, on the left hand side, the  7x  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  4  •  (x-70)  = 0

Equations which are never true:

5.2      Solve :    4   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

5.3      Solve  :    x-70 = 0

Add  70  to both sides of the equation :

                     x = 70

One solution was found :

x = 70

An expression is combination of variables, numbers and operators.

The given expression is [tex](\sqrt[6]{x^5} )^7[/tex]

We have an exponential property [tex]\sqrt[b]{x^a} =x^\frac{a}{b}[/tex]

By using this property we solve the given expression  [tex](\sqrt[6]{x^5} )^7[/tex]

We have to convert to rational exponent.

[tex](\sqrt[6]{x^5} )^7=(x^\frac{5}{6})^7[/tex]

=[tex]x^\frac{35}{6}[/tex]

Hence, [tex](\sqrt[6]{x^5} )^7[/tex] expression can be written in rational exponent as [tex]x^\frac{35}{6}[/tex]

The mean height for each sample from the basketball team will be 79, 77.5, 79, 78.5, 80, and 78.5

For sample 1, the mean will be:

= (78 + 80)/2 = 79.

For sample 2, the mean will be:

= (78 + 77)/2 = 77.5

For sample 3, the mean will be:

= (78 + 80)/2 = 79

For sample 4, the mean will be:

= (80 + 77)/2 = 78.5

For sample 5, the mean will be:

= (80 + 80)/2 = 80

The value of x from the given figure is 8

A triangle is a 2-dimensional shape with 3 sides an interior angle

Since the sum of the interior angles of a triangle is 180 degrees, hence;

8x - 4 + 76 + 44 = 180

8x + 116 = 180

8x = 180 - 116

8x = 64

x = 64/8

x = 8

Hence the value of x from the given figure is 8

Answer:

What is the difference between entering a formula and entering data ??

1. The area of the triangle = 40 m².

2. The area of the semicircle = 64.3 m²

Area = 1/2(base × height)

Area = 1/2(πr²)

1. Area of the Triangle = 1/2(base × height) = 1/2(10 × 8)

Area of the triangle = 40 m².

2. Use Pythagorean Theorem to find the hypotenuse of the triangle which is the diameter of the semicircle.

Hypotenuse = √(10² + 8²) = 12.8 m

Radius of the semicircle = 12.8/2 = 6.4 m

Area of the semicircle = 1/2(3.14 × 6.4²) = 64.3 m²

15 days

Step-by-step explanation:

if she eats 1/3 cup of outmeal each day then in 3days she will have eaten 1 cup so to get to 2cups he will have to eat for 3 more days so it goes 3 days by 3 days this will be easy to do on a number line but you could also just multiplying the 3days times the 5 cups because thats how many cups you want to get to finish so it will be 15 the 15 days it took me time to understand ‍ hope this was helpful

The number of days is 15 days.

A rate is a ratio that compares two quantities of DIFFERENT. kinds of UNITS. A unit rate has a denominator of 1 unit when the rate is written as a fraction. To write a rate as a unit rate: divide the numerator and the denominator of the rate by the denominator.

here, we have,

to determine the number of days

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

Size = 5 cups

Rate = 1/3 cup per day

The question illustrates unit rates

A unit rate is a rate in which the denominator of a ratio is 1 unit.

In other words, it is the amount of something per one unit of another thing.

Using the above as a guide, we have the following:

Number of days = 5/(1/3)

Evaluate the quotient

Number of days = 15/1 days

This gives

Number of days = 15 days

Hence, the number of days is 15

The total possble combinations = 5 * 5 = 25 ways.

The number of ways to get exactly 12

The ways to get > 12

= 3,10  4,9  4,10  5,8  5,9  5,10  =  6 ways.

So the number of ways to get < 12 = 25 - 4 - 6 = 15 ways.
