Answer:

c) 32°

Step-by-step explanation:

The bisector of an angle is the line or line segment that divides the angle into two equal parts.  So Ray HJ divides ∠GHI into 2 equal parts.

Therefore, ∠GHJ = ∠IHJ

As we are told that ∠IHJ = 32° then ∠GHJ = 32°

10.4476119402

Step-by-step explanation:

If you want a reasonable answer it would be 10.44 or 10.4!

Step-by-step explanation:

all coefficients are integers, the rational zeros theorem can be applied.

that means each rational solution ("root") x = p/q, written in most simplified terms so that p and q are relatively prime, can be found for the polynomial

an×x^n + an-1×x^(n-1) + ... + a1×x + a0

p is an ± integer factor of the constant term a0, and

q is an ± integer factor of the leading coefficient an.

in our case here

an = a4 = 1

a0 = 8

the only factor for 1 is ±1.

the factors for 8 are

±1, ±2, ±4, ±8

so, we get

1/1, 2/1, 4/1, 8/1, -1/1, -2/1, -4/1, -8/1, 1/-1, 2/-1, 4/-1, 8/-1, -1/-1, -2/-1, -4/-1, -8/-1

that leaves us with the different values of

1/1, 2/1, 4/1, 8/1, -1/1, -2/1, -4/1, -8/1

sorted from smallest to largest

-8/1, -4/1, -2/1, -1/1, 1/1, 2/1, 4/1, 8/1

or simply

-8, -4, -2, -1, 1, 2, 4, 8

Answer:

supplementary

Consecutive angles are supplementary (A + D = 180°). If one angle is right, then all angles are right. The diagonals of a parallelogram bisect each other. Each diagonal of a parallelogram separates it into two congruent triangles.

Answer:

Supplementary

Step-by-step explanation:

The consecutive angles of a parallelogram are supplementary.

Two angles that add up to 180° are called supplementary angles.

This can be proven by creating a parallelogram and extending all segments to create two parallel lines transversing another set of two parallel lines.

I drew a diagram of this shape and considering that all the opposite lines are parallel, the central shape is a parallelogram.

Looking at the diagram attached, we know that the angle of a straight line is 180° (represented by the yellow of Angle 1 and the pink angle next to it) All angles of the same color are congruent by angle theorems consisting of corresponding and vertical angles.

If pink is x, and yellow is y, then we can say that x + y = 180°

So, therefore we can say that the consecutive angles of the parallelogram (Angle 1 and Angle 2) sum up to 180°, because they are made up of one pink angle and one yellow angle ( x and y )

Using proportions, it is found that you would expect to get a sum of 3 22 times.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

When two dice are rolled, there are 36 total outcomes. 2 of them, (1,2) and (2,1), result in a sum of 3, hence the proportion is given by:

p = 2/36 = 1/18.

Out of 396 tosses, the expected value is given by:

E = 1/18 x 396 = 22.

Answer:The  median of the distribution is (first option)

Step-by-step explanation:

The values on the given table are presented as follows;

Value of spin: 0,1,2,5,10

Probability: 0.4,0.2,0.2,0.1,0.1

To find the median, we calculate the cumulative probabilities to find the value of the spin art which the cumulative probability is 0.5 as follows;

Cumulative probability, starting from the left, is therefore;

Probability for spin of 0, 0.4 + Probability for spin of 1, 0.2 = 0.6
Therefore, given that the probability of 0.5 occurs within the Value of Spin 1, the median of the probability distribution is 1

The solution is : The  median of the distribution is (first option) 1

In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value.

An equation is formed of two equal expressions. There is no solution set of the equation 3x+13 = 3(x+6)+1.

The equation can be solved in the following manner,

[tex]3x+13 = 3(x+6)+1\\3x+13=3x+18+1\\3x+13=3x+19[/tex]

The way to find sidewalk area :")

Answer:

Exact - 40n m²

Step-by-step explanation:

Exact area of the sidewalk - n * (11 m)² - n * (9 m)²

- n * 121 m²- n * 81 m²

Exact area of the sidewalk - 40n m²

To find the approximate area of side walk let us substitute pi equals 3.14.

40*3.14 m²

Approximate area of the side walk - 125.6 m²

Therefore the exact area is 40n m² , the approximate area is 125.6 m²

Answer:

Step-by-step explanation:

Let function p(x) be the price that is reduced by 15% if the bill is x dollars.

Since the price is not payed in full 100% is reduced by 15% we only pay

100 - 15 = 85 % of the original price.

p(x) = x· (100% - 15 %)  = x· 85% = 0.85 x

The function used to calculate any bill that is reduced by 15% is:

p(x) = 0.85x

x - is the bill before being reduced by the coupon

Answer:

D.

Step-by-step explanation:

We know that to find unit price, we divide the unit in the numerator by the quantity in the denominator.

For the first option, we must put $1.49 as the numerator and 8 as the denominator. It will then look like this:

For our second option, we must put $2.29 as the numerator, and 12 as the denominator. It will look like this:

For our third option, we must put $2.75 as the numerator, and 15 as the denominator. It will look like this:

For our final option, we must put $3.89 as the numerator, and 20 as the denominator. It will look like this:

Therefore, the last option is the best buy because $0.18625 > $0.18333.

The salaries will be the same in year 20 and she will be earning $80,000. So, the first option is correct.

The equation of the straight line has its slope and given point.

If we have a non-vertical line that passes through any point(x1, y1) has gradient m. then general point (x, y) must satisfy the equation

                  y-y₁ = m(x-x₁)

Which is the required equation of a line in a point-slope form.

We will first create an equation to represent the data.

To find the slope we use the formula

m = (y₂-y₁)/(x₂-x₁)

= (60,000-55,000) / (12-10)

= 5,000/2 = 2500

Writing this in point-slope form, we have

y-y₁ = m(x-x₁)

y-55,000 = 2500(x-10)

Converting to slope-intercept form,

y-55,000 = 2500 × x - 2500 × 10

y - 55,000 = 2500x - 25,000

y = 2500x + 30,000  

Now we set this equal to the equation from the graph:

2500x + 30,000 = 2000x + 40,000

Subtract 2000x from both sides:

2500x + 30,000 - 2000x = 2000x + 40,000 - 2000x

500x + 30,000 = 40,000

500x = 40,000 - 30,000

500x = 10,000

x = 10,000/500

x = 20

The salaries will be the same in year 20.

y= 2000(20) + 40,000

y= 40,000 + 40,000

= 80,000

The salary in year 20 will be $80,000.

Answer:

Option c

(3,1)

Step-by-step explanation:

Solving system of equations:

y = -x + 4  ----------(I)

y = x - 2 -----------(II)

Add equation (I) & (II). So, x will be eliminated and we can find the value of y.

      (I)       y = -x + 4

     (II)       y = x -  2   {Now add}

               2y = 2

Divide both sides by 2

                y = 2/2

y =1

Substitute y = 1 in any of the equations. Here, we are substituting in equation  (II)

1 = x - 2

1 + 2 = x
