Line c has a slope of -9/2. line d is parallel to like c. what is the slope of line d?

In this case, we must use trigonometry to find the value of x:

        [tex]tan(\alpha )=\frac{side-opposite-angle}{side-beside-angle} \\tan(70) = \frac{x}{3} \\3*tan(70) = x\\x = 3*tan(70)\\x = 8.24[/tex]

Thus the value of x rounded to the nearest tenth is 8.2

Step-by-step explanation:

The fraction 6/10 can be reduced to simplify the addition.

  9/5 -(-6/10) = 9/5 +6/10 = 9/5 +3/5

  = 12/5 = 2.4

The value of each angle for the given regular polygon is 161.05°.

A regular polygon can be defined as a polygon having all of its sides and angles equal to one another. The expression for each angle of a regular polygon is 180(n - 2)/n.

Suppose each angle of the regular polygon be x.

Since the sum of all the interior angles of a regular polygon with n sides is given as 180(n - 2).

As per the given problem the number of sides n = 19.

Then, the following equation can be written as follows,

19x = 180(19 - 2)

=> 19x = 180 × 17

=> x = (180 × 17)/19

       = 161.05

Hence, each angle of the given regular polygon with 19 sides is 161.05°.

Answer:

1. Alike

2. Opposite

3. Common factor

Step-by-step explanation:

1. To have a positive number, you can only have alike signs, for example, any positive number times another positive number is always positive. The same is true for negative numbers multiplied by each other.

2. To have a negative number, there has to be one negative number and one positive number being multiplied together. Always. For example:

3 x -5 =-15

10 x -1 = -10

3. You can factor out a common factor to simplify a polynomial before you factor it.

Answer:Examples of quadratic equations are: 6x² + 11x – 35 = 0, 2x² – 4x – 2 = 0, 2x² – 64 = 0, x² – 16 = 0, x² – 7x = 0, 2x² + 8x = 0 etc. From these examples, you can note that, some quadratic equations lack the term “c” and “bx.”

Step-by-step explanation:

A quadratic equation in the variable x is an equation of the form ax^2 + b x + c = 0, where a, b, c are real numbers, a ≠ 0.

Quadratics can be defined as a polynomial equation of a second degree, which implies that it comprises a minimum of one term that is squared. It is also called quadratic equations.

The standard form of a quadratic equation is;

Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = ax^2 + bx + c where a, b, c, ∈ R and a ≠ 0.

These are the following examples of the quadratic equation;

x^2-2x

x^2+5x+6

x^2-5x

Any equation of the form p (x) = 0, where p (x) is a polynomial of degree 2, is a quadratic equation.

If we write the terms of p (x) in decreasing order of their degrees, then we get the standard form of the equation.

Divide the area by the side length to find the length of the other side:

227.9/5.3 = 43 m

now calculate the perimeter:

43 + 43 + 5.3 + 5.3 = 96.6m

Answer: 96.6m

Answer:

96.6 m

Step-by-step explanation:

Let the length of the other side b x m .

Then the area = 5.3 * x

227.9 = 5.3x

x = 227.9 / 5.3

= 43 m

So the perimeter = 2 * (width + length)

= 2(5.3 + 43)

= 2 * 48.3

= 96.6 m

Answer:

(4x+5)=57 (2x+7)=33

Step-by-step explanation:

So, if a complementary angle is 90, our equation is (4x+5)+(2x+7)=90, and we get 13, so x=13, and we put that into our equation, so our first equation is now

Our first solution is (4(13)+5), which equals 57, and our second model is (2(13)+7), which equals 33, hence the angles' degrees are 57 and 33.

Unit conversion is a way of converting some common units into another. Kari cannot afford to see Genoa, because it would put her $84. 48 over budget.

Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.

The cost of the Kari visiting the Vatican, Rome, Naples, Venice, and Milan are €68.77, €95.41, €71.06, €113.38, and €49.69. Therefore, the total cost of visiting these places would be,

Total Cost = €68.77 + €95.41 + €71.06 + €113.38 + €49.69

                  = €398.31

Now, as it is given that 1$ is equal to 0.6859€, therefore, if we convert the amount that is already spent by Kari to visit these places in dollars, we will get,

[tex]\rm Total\ cost = \dfrac{398.31 }{0.6859} = \$\ 580.72[/tex]

The amount that is left with Kari,

[tex]\rm \text{Amount left with Kari} = (Budget\ of\ Kari)-(Total\ cost)[/tex]

                                    [tex]= \$585-\$580.72\\\\=\$4.28[/tex]

Also, the cost of visiting Genoa is €60.85, now, if the cost is converted to dollars we will get the cost to visit Genoa,

[tex]\text{Cost of visiting Genoa} = \dfrac{60.85}{0.6859}=\$88.72[/tex]

Thus, the cost of visiting Genoa is $88.72, while the amount of budget that is left with Kari is $4.28, therefore, Kari cannot afford to see Genoa, because it would put her $84. 48 over budget.

Answer:

8 (or 8.4)

Step-by-step explanation:

First, the problem states the words: Distinct and positive.

That means that the smallest number we can use is 0.

We can make 10 blanks for 10 numbers for us to fill in.

_ _ _ _ _ _ _ _ _ _

Since 10 is an even number, and the median is not one single number, it will be the middle of the two numbers.

In this case, our two numbers are the 5th and 6th blank.

Any two numbers can be used, as long as they are the same actual value from 10.

Let us first put in the numbers we can, which are the numbers before the two middle blanks.

0,1,2,3, _ _ _ _ _ _

To find the median between two numbers, we can do:

(a+b) divided by 2 = median

We can use the smallest following number, 4. Then the 6th number will have to be 16 for 10 to be in the middle.

Also try the largest possible number for the 5th blank, 9. Then the 6th number will be 11.

4+16 and 9+11 both equal 20, and 20 divided by 2 is 10. So both of these work.

Now let's place the other numbers in for these two equations.

0,1,2,3,4,16,17,18,19,20

0,1,2,3,9,11,12,13,14,15

If we add the numbers of each together, we get:

0,1,2,3,4,16,17,18,19,20=100

0,1,2,3,9,11,12,13,14,15= 80

If we now divide each sum by 10 (to find the average) we get:

10

8

Since both of these were the most we could go, one with the 5th number as small as possible and one with the 5th number as large as possible.

Since the smaller answer we got was 8, the answer must be 8.
