You have purchased 5 weekday hours.

Step-by-step explanation:

Parking hours purchased = 26

Cost per hour on weekday = $2

Cost per hour on weekend = $10

Total spent = $220

Let,

Number of hours on weekdays = x

Number of hours on weekend = y

According to given statement;

x+y=26      Eqn 1

2x+10y=220    Eqn 2

Multiplying Eqn 1 by 10

[tex]10(x+y=26)\\10x+10y=260\ \ \ Eqn\ 3\\[/tex]

Subtracting Eqn 2 from Eqn 3

[tex](10x+10y)-(2x+10y)=260-220\\10x+10y-2x-10y=40\\8x=40[/tex]

Dividing both sides by 8

[tex]\frac{8x}{8}=\frac{40}{8}\\x=5[/tex]

Answer:

1) angle bisector

2) w = 72°

3) t = 44°

4) t = 51°

5) FG = 16 units

Step-by-step explanation:

1) Given that, ∠VYW ≅ ∠WYV

The line which cuts any angle into equal halves is angular bisector of the angle

⇒ YW is angle bisector

2) In a triangle, sum of two interior angle is equal to exterior angle of other side.

⇒ w-41° + w-31° = w.

⇒ w = 72°

3) Sum of interior angles in a pentagon is 540°

(For a n sided it is (n-2)180° )

⇒ 149° + 139° + t+32° + 3t +t = 540°

⇒ t = 44°

4) sum of all exterior angles taken one at each vertex = 360°

⇒ 2t-50° + 46° + 2t + 34° + 2t-50° + 34° + 40° = 360°

⇒ t = 51°

5) Here, by comparing ΔHGF and ΔHIF

   ∠GHF = ∠IHF

  ∠HGF = ∠HIF

 and HF is common side for both triangles

⇒  ΔHGF ≡ ΔHIF ;  i.e) ΔHGF , ΔHIF are congruent triangles

⇒ FG = FI = 16 units

Answer:

d=125

Step-by-step explanation

edge 2020

The value of d, which is the bottom right angle formed on line s when cut by transversal q, is 125 degrees due to the alternate exterior angles being congruent on parallel lines.

When two parallel lines are crossed by a transversal, certain angles are equal due to the properties of parallel lines. The upper left angle on line s when intersected with the transversal q is given as 125 degrees; this is the alternate exterior angle relative to the bottom right angle formed on line s also intersected by q, which is known as d degrees in the question.

According to the alternate exterior angles theorem, these two angles are equal because the lines r and s are parallel. Therefore, the bottom right angle on line s, or d degrees, is also 125 degrees, because alternate exterior angles are congruent when two parallel lines are cut by a transversal.

Answer:

The number of visit so that both plan cost same is 10 .

Both the plan has equivalent choice of benefit

Step-by-step explanation:

Given as :

A gym has two membership plans.

For Gold plan

The charge per month = $50  

The charge per visit = $3

For Platinum plan

The charge per month = $20  

The charge per visit = $6

Let The number of visit for which each plan be same = n visits

Now, According to question

∵ Each plan cost to be same

So,

The charge per month for gold plan+ The charge per visit × numbers of visit = The charge per month for platinum plan+ The charge per visit × numbers of visit

I.e $50 + $3 × n = $20 + $6 × n

Or, $50 - $20 =  $6 × n  -  $3 × n

Or, $30 = ($6 - $3) × n  

Or, $30 = $3 × n  

∴ n = [tex]\dfrac{30}{3}[/tex]

I.e n = 10

So, The number of visits = n = 10

Now, For Gold plan

The charge per month = $50  

The charge per visit = $3 × 10 = $30

So, Total charge for gold plan = $50 + $30 = $80

Similarly For Platinum plan

The charge per month = $20  

The charge per visit = $6×10 = $60

So, For Platinum plan ,total charge = $20 + $60 = $80

Hence, The number of visit so that both plan cost same is 10

and both the plan has equivalent benefit. Answer

The cost of adult and kid tickets, we set up two equations representing the total cost for separate groups and use the elimination method to solve the system of linear equations. Once we solve for one ticket type, we can use its value to find the cost of the other ticket type.

The problem presented is a system of linear equations where we have two unknowns: the cost of an adult ticket and the cost of a kid ticket. We can set up the two equations based on the given information:

40A + 26K = 486.70 (First group's total cost)

21A + 31K = 332.45 (Second group's total cost)

To solve this system, we can use either substitution or elimination methods. For simplification, let's use the elimination method:

Multiply the second equation by 2: (2 x 21A) + (2 x 31K) = 2 x 332.45, which gives us 42A + 62K = 664.90.

Now subtract the first equation from this new equation: (42A + 62K) - (40A + 26K) = 664.90 - 486.70, resulting in 2A + 36K = 178.20.

Divide the entire equation by 2: A + 18K = 89.10.

We now have an easier equation to work with along with our original first equation.

To find the value of one variable, we could substitute the value of A from the first equation (using the second simplified equation) into the second equation and solve for K.

Once we have the value of K, we can substitute it back into either original equation to solve for A.

These steps will give us the exact cost of an adult ticket (A) and a kid ticket (K).

Answer:

3(6y-11)+2y=7

18y-33+2y=7

20y-33=7

20y=40

y=40/20

y=2

Put equation 1 into equation 2.

3(6y - 11) + 2y = 7

18y - 33 + 2y = 7

18y + 2y = 40

20y = 40

y = 2

x = 6(2) - 11

x = 12 - 11

x = 1

Answer:

x =15°

Step-by-step explanation:

Given that the horizontal line is 90° to the vertical line, then both the angles have to necessarily add up to 90° i.e

(5x-10)° + 25° = 90°

5x - 10 + 25 = 90

5x + 15 = 90  (subtract 15 from both sides)

5x = 90 - 15

5x = 75   (divide both sides by 5)

x = 75 / 5 = 15°

Answer:

61 miles.

Step-by-step explanation:

Given: driving north for 11 miles and drive east for another 60 miles.

As given in the question, the travelling pattern show a right angle triangle, where hypotenuse line is the way to return back directly to starting point. As shown in picture attached.

∴ we can say, adjacent (a) is 11 miles and opposite (b) is 60 miles

Now, using Pythagoras theorem to get distance to return.

[tex]h^{2} = a^{2} +b^{2}[/tex]

⇒ [tex]h^{2} = 11^{2} +60^{2}[/tex]

⇒ [tex]h^{2} = 121+3600= 3721[/tex]

⇒ [tex]h= \sqrt{3721}[/tex]

∴[tex]h= 61[/tex]

∴ 61 miles need to be travel to return back directly to starting point.

Answer:

The rent owe by me is Rs 1435

The rent owe by roommate is Rs 1360

Step-by-step explanation:

Given as :

The total rent of the room = x = Rs 2795

Let The room rent pay by friend = Rs y

And The room rent pay by me = Rs z

Now, According to question

The room rent pay by me = Rs 75 + room rent pay by roommate

i,e Rs z = Rs 75 + Rs y

Now, Again

The total rent of the room = The room rent pay by me + room rent pay by roommate

Or, x = Rs z + Rs y

Or, Rs 2795 = (Rs 75 + Rs y) + Rs y

Or, 2795 = 75 + 2 y

Or, 2 y = 2795 - 75

Or, 2 y = 2720

∴  y = [tex]\dfrac{2720}{2}[/tex]

i.e y = Rs 1360

So, room rent pay by friend = y = Rs 1360

And,The room rent pay by me = Rs 75 + room rent pay by roommate

Or,The room rent pay by me = Rs 75 + Rs 1360

So,he room rent pay by me = Rs 1435

Hence,The rent owe by me is Rs 1435

And ,The rent owe by roommate is Rs 1360    Answer

Answer: OPTION B.

Step-by-step explanation:

When parallel lines are cut by a transversal several angles are formed.

There are pairs of angles called "Alternate Interior angles".

 These angles are not adjacent and they are located between the parallel lines, and on opposite sides of the transversal.

By definition, they are are congruent, or, in other words the measure of Alternate Interior angles are equal.

In this case, you can identify that the [tex]\angle 8[/tex] and the [tex]\angle 2[/tex] are Alternate Interior angles.

Based on the data given in the exercise, you know that the measure of the angle 8 is:

Answer:

Step-by-step explanation:

a + p = 165......a = 165 - p

1.75a + 2.5p = 337.50

1.75(165 - p) + 2.5p = 337.50

288.75 - 1.75p + 2.5p = 337.50

-1.75p + 2.5p = 337.50 - 288.75

0.75p = 48.75

p = 48.75 / 0.75

p = 65 <==== 65 lbs of peaches were sold

a + p = 165

a + 65 = 165

a = 165 - 65

a = 100 <=== there were 100 lbs of apples sold

check...

1.75a + 2.5b = 337.50

1.75(100) + 2.5(65) = 337.50

175 + 162.50 = 337.50

337.50 = 337.50 (correct)

1)

Scientists are studying a 500 grams sample of a radioactive element, which has an annual decay rate of 11%

∵ The initial amount is 500 grams

∴ a = 500

∵ The annual decay rate is 11%

∴ r = 11% = 11 ÷ 100 = 0.11

∵ b = 1 - r ⇒ decay

∴ b = 1 - 0.11 = 0.89

- We need to find how many grams of the sample would be left

  after 10 years

∴ x = 10

- Substitute all of these values in the form of the exponential function

∵ [tex]y=500(0.89)^{10}[/tex]

∴ y = 155.9085996

- Round it to 2 decimal places

In 2000, the population of an Ohio town was 140,212. The population is expected to grow at a rate of 2.5% each year

∵ The population of an Ohio town was 140,212

∴ a = 140.212

∵ The population is expected to grow at a rate of 2.5% each year

∴ r = 2.5% = 2.5 ÷ 100 = 0.025

∵ b = 1 + r ⇒ growth

∴ b = 1 + 0.025 = 1.025

- We need to find the population in 2040

∵ The number of years is 2040 - 2000 = 40 years

∴ x = 40

- Substitute all of these values in the form of the exponential function

∵ [tex]y=140212(1.025)^{40}[/tex]

∴ y = 376478.1709

If f(4a) = 80, then the value of "a" is 4.2

Solution:

Given that cost for the olive oil used to fill the containers on the tables in an Italian restaurant is given by the function:

f(x) = 5x – 4

where "x" represents the number of quarts of olive oil

f(x) represents the quarts of oil used

To find: value of "a" when f(4a) = 80

Substitute x = 4a in given function

f(4a) = 5(4a) - 4

80 = 20a - 4

20a = 84

10a = 42

a = 4.2

Thus the value of "a" is 4.2

We want to know the value of a factor, given that we know f(4a) = 80 and the function f(x).

The value of a is 4.2

Here we start with the function f(x) = 5x - 4

Now we know that:

f(4a) = 5*(4a) - 4 = 80

Then we can just solve the above equation to find the value of a:

5*(4a) - 4 = 80

20*a - 4 = 80

20*a = 80 + 4 = 84

a = 84/20 = 4.2
