Answer:

The percent of increase from 6 to 9 is 50%

Step-by-step explanation:

Percentages

To calculate the percentage increase:

Work out the difference (increase) between the two numbers you are comparing.

Increase = New Number - Original Number.

Divide the increase by the original number and multiply the answer by 100.

We are required to find the percent increase from 6 to 9. Here: New number=9, Original number = 6

Increase = 9 - 6 = 3

Divide 3 by 6 and multiply the answer by 100:

3 / 6 * 100 = 50%

The percent of increase from 6 to 9 is 50%

The percent of increase from the number 6 to 9 is 50 percent.

The given numbers are 6 and 9.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

The difference of the given numbers

= 9-6

= 3

The percent of increase = 3/6 ×100

= 0.5×100

= 50%

Therefore, the percent of increase from the number 6 to 9 is 50 percent.

Answer:

b= 26

Step-by-step explanation:

First, find the slope using the slope formula,

[tex]m=\frac{5-\left(-2\right)}{-3-\left(-4\right)}[/tex]       solve and simplify, m=7

plug in one pair of coordinates for the y and x for the slope intercept form,

(I'll just use (-3,5))

y=mx+b

5=7(-3)+b

5=-21+b

5+21=21-21+b

b=26                       After solving the problem, b=26

Rewrite the whole as a fraction using  9  as the denominator :

   6 =  —  =  —————

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 :

6.1    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:

 -v-59

 ————— • 9 = 0 • 9

   9  

Now, on the left hand side, the  9  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  -v-59  = 0

Solving a Single Variable Equation:

6.2      Solve  :    -v-59 = 0

Add  59  to both sides of the equation :

                     -v = 59

Multiply both sides of the equation by (-1) :  v = -59

Answer:

Measure of third angle = 80°

Step-by-step explanation:

Property of an isosceles triangle,

Opposite angles of the equal sides of an isosceles triangle are equal in measure.

Since, base angles of an isosceles triangle are equal,

(3x + 2) = (5x - 30)

5x - 3x = 2 + 30

2x = 32

x = 16

Now measure of the base angles will be = (3×16) + 2 = 50°

Let the measure of third angle = y°

Since, sum of interior angles of a triangle = 180°

50° + 50° + y° = 180°

y + 100 = 180

y = 80°

Therefore, measure of third angle is 80°.

Step-by-step explanation:

Probability = expected outcome/total outcome

If a bag contains 3 red balls, 8 blue balls and 11 white balls, then the total outcome will be;

Total outcome = 3 + 8 + 11 = 22 balls

Since we are drawing two balls with replacement;

Probability of drawing red ball = number of red/total outcome = 3/22

Probability of drawing white ball = number of while/total outcome = 11/22 = 1/2

Probability of drawing red first and then white = 3/22 * 1/2

Probability of drawing red first and then white  = 3/44

To the nearest tenth, 3/44= 0.1

The value of the unknown fourth interior angle of the polygon is 114 degrees.

Hence option B)114° is the correct answer.

A polygon is simply a two-dimensional a plane shape enclosed by line segments called sides.

The formula for calculating the sum of interior angles of a polygon is;

S =  ( n − 2 ) × 180°

Where n is the number of sides.

Given that the polygon is the diagram has 4 sides, n = 4

Hence

the sum of interior angles of the polygon is;

S =  ( n − 2 ) × 180°

S =  ( 4 − 2 ) × 180°

S = 2 × 180°

S = 360°

Now, we add the total interior angles in the given polygon and equate to the sum of interior angles of a polygon with 4 sides.

82° + 51° + 113° + x = 360°

246° + x° = 360°

x = 360° - 246°

x = 114°

The value of the unknown fourth interior angle of the polygon is 114 degrees.

Hence option B)114° is the correct answer.
