Answer:
[tex] \sf \: x = {20}^{o} [/tex]
Step-by-step explanation:
Let's take the value of y as,
→ y = 90°
(Because, it is a right angle)
Forming the equation,
→ x + y + 70° = 180°
Now the value of x will be,
→ x + y + 70° = 180°
→ x + 90° + 70° = 180°
→ x + 160° = 180°
→ x = 180° - 160°
→ [ x = 20° ]
Hence, the value of x is 20°.

Define tractable problem.An algorithm that can solve a tractable problem in a polynomial amount of time. Polynomial describes the upper bound. An intractable problem is one that cannot be resolved in a polynomial amount of time. Exponential is the lower bound.
Here,
Tractable refers to "manageable," hence the word is used to indicate issues that can be resolved in a reasonable amount of time.
This leads to the definition of a problem as tractable as the existence of a polynomial-time algorithm that can solve it.

I really need help on a) Complete the frequency tree, I don't know how to work that one out.
Answers
The missed value in the frequency tree is 224.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
Given that 400 people are asked if they drink tea.
7/10 say Yes and 20% of the people who say Yes drink at least 3 cups each day
7/10 of 400 is 280
Which means 280 people drink tea.
The remaining people does not drink tea.
Remaining =400-280=120.
Now let us find 20% of 280
20/100×280
0.2×280=56
So 56 drink at least 3 cups each day.
280-56=224
So 224 people drink tea but not three cups.
Hence, the missed value in the frequency tree is 224.

1.write a function that correctly depicts this scenario
2. How much will this cost 10 years from now ( round your answer to the nearest cent)
3 how much did this cost 15 years ago ( round your answer to the nearest cent
Answers
Answer:
The function that correctly depicts the scenario is:
cost(n) = 18.50 * 1.06^n
This function takes the number of years n as input and returns the cost of eating at the all-you-can-eat buffet after n years.
The cost of eating at the all-you-can-eat buffet 10 years from now can be calculated as follows:
cost(10) = 18.50 * 1.06^10 ≈ $30.59
The cost of eating at the all-you-can-eat buffet 15 years ago can be calculated as follows:
cost(-15) = 18.50 * 1.06^(-15) ≈ $8.01

The Bolwarra resident also raced in two rounds of the Australian Formula 4 Championship with AGI Sport and finished all but one race in the top seven.[2] However, due to Mansell being a guest driver he was not classified in the standings.For 2020 Mansell moved over to the United Kingdom to race full-time in the F4 British Championship, partnering Zak O'Sullivan and Matias Zagazeta at Carlin. Whilst the Australian only managed to score one win at the Brands Hatch Circuit, in contrast to O'Sullivan's nine over the course of the season, he did score four more podiums, which included two third places and a second place at the final round. This led to Mansell finishing seventh in the championship at the end of the year.

which equation represents a line perpendicular to the given line x-4y=7
Answers
The equation of the line perpendicular to x - 4y = 7 can be written as:
y = 4*x + b
Where b could be any real number.
Which equation represents a line perpendicular to x - 4y = 7?Two lines are perpendicular if the product between the slopes of the lines is equal to -1.
Where a general line in the slope-intercept form is written as:
y =a*x +b
And the given line is:
x - 4y = 7
Writing this in the slope-intercept form we will get:
-4y = -x - 7
y = (-1/4)*x + 7/4
So the slope is -1/4, then the slope of our line must be such that:
a*(-1/4) = -1
a = -4*-1 = 4
a =4
So the line perpendicular to the given one is:
y = 4*x + b
Where b can be any real number.

If a trapezoid has an area of 135cm^2 and it’s height is 10cm and one base is 12 cm, find the other base length.
thxxx <333
Answers
The length of other base is 15 cm.
The area of a trapezoid can be found by using the formula:
Area = (b1+b2) * h / 2 where b1 and b2 are the lengths of the bases, and h is the height.
Given that the area of the trapezoid is 135 cm^2, the height is 10 cm, and one base is 12 cm, we can substitute these values into the formula to find the length of the other base.
Area = (b1+b2) * h / 2 = 135cm^2
We can solve for the other base length by isolating b1
b1 = 2*Area/h - b2
b1 = 2*135/10 - 12 = 27 - 12 = 15
So, the other base length is 15 cm.
Therefore, The length of other base is 15 cm.

As per the decimal number system, the cost of 25 tickets is $32.5
The term decimal in math is defined as the numbers, which consist of two parts namely, a whole number part and a fractional part separated by a decimal point.
Here we have given that the product of 3 student tickets at $4.
Here we have know that the ticket cost for 3 students is $4.
Then the cost of one person is calculated by dividing the cost by the number of students then we get,

=> 1.3
So, if the cost for one person or ticket is $1.3 then the cost of 25 tickets is calculated as,

The perimeter of a rectangle is 54cm. If the length of rectangle is 18cm,find its area
Answers
Answer:
162cm squared
Step-by-step explanation:
The perimeter of a rectangle can be calculated by length+length+width+width.
We know the length is 18, so our equation of finding the width is:
54-(18*2) divided by 2.
54-36=18.
18/2=9.
The area of a rectangle can be calculated by length * width. We already have the length, and now we have the width.

Answers
The final value of a_5 is 27a.
The equation a_n=a_{n-1}+5a is a recursive formula that gives the value of a_n in terms of the value of a_{n-1}. To find the value of a_5, we need to apply this formula repeatedly, starting with the given initial value of a_1=7a.
Using the recursive formula:
a_2 = a_1 + 5a = 7a + 5a = 12a
a_3 = a_2 + 5a = 12a + 5a = 17a
a_4 = a_3 + 5a = 17a + 5a = 22a
a_5 = a_4 + 5a = 22a + 5a = 27a
so a_5 = 27a
This is the final result and no need to calculate more.
Thus the final value of a_5 is 27a.
