Answer:

68

Step-by-step explanation:

The shape is 5 sides polygon.

Sum of interior angles of a 5 sided polygon = 540,

7x + 4 + 8x + 3 + 4x + 8 + 10x - 4 + 6x + 4 = 540

7x + 8x + 4x + 10x + 6x + 4 + 3 + 8 + 4 - 4 = 540

35x + 4 + 3 + 8 = 540

35x + 15 = 540

35x = 540 - 15

35x = 525

Divide 35 on both sides,

x = 525 / 35

x = 15

Angle R = 4x + 18

Substitute the value of x,

Angle R = 4 ( 15 ) + 8

             = 60 + 8

Angle R = 68

Here is how you solve for x:

9x - 43/ 3x + 29

1: First, you add like terms. In this case, it is 9x and 3x. 9x + 3x= 12x

2: Then, you have -43 and 29 left. -43 + 29= -14 because you do 43 - 29 and keep the sign of the larger number.

3: Lastly, we have a one-step equation left to solve: 12x-14. So, now we do this:

- divide both sides by 12.

- -14/12= 1.67

x= -1.67

Answer:

10 9/64

Step-by-step explanation:

To answer this, multiply '1 3/8 miles' by '7 3/8.'  

The improper fraction form of '1 3/8' is 11/8, and that of 7 3/8 is 59/8.

Multiplying 11/8 by 59/8, we get 649/64, or (as a mixed number) 10 9/64

Answer:

$7,350.00

Step-by-step explanation:

To find out the total amount of money, you need to know the total amount of tickets sold.

So, find out what 20% of 350 is for the second hour and add it to the 350 from the first hour

350 x 0.20 = 70

350 + 70 = 420 total tickets

now you multiply 420 by the amount of money per ticket in order to know the price for all the tickets in both hours

420 x 17.50 = 7,350 dollars total

Answer:

Asymptotic discontinuities at [tex]x = (-2)[/tex] and [tex]x = 4[/tex].

Step-by-step explanation:

A linear function has an asymptotic discontinuity at [tex]x = a[/tex] if [tex](x - a)[/tex] is a factor of the denominator after simplification.

The numerator of this function, [tex](x - 1)[/tex], is linear in [tex]x[/tex].

The denominator of this function, [tex](x^{2} - 2\, x - 8)[/tex], is quadratic in [tex]x[/tex]. Using the quadratic formula or otherwise, factor the denominator into binominals:

[tex]\begin{aligned}y &= \frac{(x - 1)}{x^{2} - 2\, x - 8} \\ &= \frac{(x - 1)}{(x - 4)\, (x + 2)}\end{aligned}[/tex].

Simplify the function by liminating binomials that are in both the numerator and the denominator.

Notice that in the simplified expression, binomial factors of the denominator are [tex](x - 4)[/tex] and [tex](x + 2)[/tex] (which is equivalent to [tex](x - (-2))[/tex].) Therefore, the points of discontinuity of this function would be [tex]x = 4[/tex] and [tex]x = (-2)[/tex].

Answer:184yards

Step-by-step explanation:

First of all, the formulae for finding the perimiter is 2xlength + 2xwidth

which can also be written as 2l + 2w

solution:

=2l + 2w

=2x33 + 2x59

=66 + 118

= 184

Therefore the perimeter of the rectangle is 184yards.

Answer:

y = 2x

Step-by-step explanation:

Use y = mx + b to write an equation. The y-intercept is zero. This is where the line crosses the y -axis, kind of the "starting point" So in the equation the b is a zero.

You can grab a couple points from the line to do a calculation for slope. BUT, you can actually SEE the slope on this line and save yourself the calculation. Starting from zero, see that you go UP 2 and OVER 1 to get to the next point. UP2OVER1 gets you to the next point and the next point. UP2OVER1 is the slope 2/1, which is 2, which is the m in the equation.

y = 2/1 x + 0

y = 2x + 0

y = 2x

**in case you have to show a calc for slope. Grab two points and do y-y, put that on top and then x-x and put that on the bottom.**

Question 2

The correct answer to the simplified form of the mixed fraction equation is determined as [tex]\frac{67x}{10} + 9[/tex].

The given fraction is written as follows;

[tex]3 (\frac{7}{5} x + 4)-2(\frac{3}{2} -\frac{5}{4} x)[/tex]

[tex]=3 (\frac{7}{5} x + 4)-2(\frac{3}{2} -\frac{5}{4} x)\\\\= \frac{21}{5} x + 12 - 3 + \frac{5x}{2} \\\\= \frac{21}{5} x +9 + \frac{5x}{2}\\\\= \frac{42x + 90+ 25x}{10} \\\\= \frac{67x}{10} + 9[/tex]

Thus, the correct answer to the simplified form of the mixed fraction equation is determined as [tex]\frac{67x}{10} + 9[/tex].

Using the z-distribution, it is found that the correct option regarding the question in the problem is given by:

B. No, since the confidence interval includes values less than 50%, his opponent may get more votes.

A confidence interval of proportions is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which:

In this problem, we have a 95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.

In this problem, the parameters are given as follows:

[tex]\pi = 0.52, n = 1000[/tex]

Hence, the bounds are given by:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.52 - 1.96\sqrt{\frac{0.52(0.48)}{1000}} = 0.489[/tex]

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.52 + 1.96\sqrt{\frac{0.52(0.48)}{1000}} = 0.551[/tex]

The lower bound is below 0.5, hence option B is correct.

C. 6cm and 7 cm

Step-by-step explanation:

The volume of a cube is calculated by finding the third power of a side length which is basically multiplying the value by itself three times (a^3 = a*a*a)

Let a represent the side length

a^3 = 250.047 cm^3 (approximately 250) we can try each option one by one to find the nearest result:

A)

the third power of 4 is 64 and the third power of 5 is 125 so this is not the answer we are looking for

B)

The third power of 5 is 125 and the third power of 6 is 216 so this is also not the answer we are looking for

C)

the third power of 6 is = 216 and the third power of 7 is 343

now 250 is between these values so this is the answer we are lookign for

The cost of 1 purse will be £14.

And, The cost of 1 watch will be £13.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The cost of 1 purse and 1 watch is £27.

The cost of 2 purses and 1 watch is £41.

Now,

Let the cost of 1 purse = x

And, The cost of watch = y

So, We can formulate;

⇒ x + y = £27    ......(i)

And, The cost of 2 purses and 1 watch is £41.

So, We can formulate;

⇒ 2x + y = £41          ..........(ii)

Subtract (i) from (ii), we get;

⇒ 2x + y - x - y = 41 - 27

⇒ x = £14

And, From equation (i), we get;

⇒ x + y = £27

⇒ £14 + y = £27

⇒ y = £27 - £14

⇒ y = £13

Thus, The cost of 1 purse will be £14.

And, The cost of 1 watch will be £13.
