Answer:
The equation of line perpendicular to given line equation and passing through point (4,3) is y = 3 x - 9 .
Step-by-step explanation:
Given as :
The given equation of one line = y = [tex]\dfrac{-1}{3}[/tex]x + 5
∵ Equation of line in slope-intercept form is written as
y = m x + c
where m is the slope of line
And c is the intercept of y
Now, Comparing given line equation with standard slope intercept line equation
∴ m = [tex]\dfrac{-1}{3}[/tex]
Slope of this line = m = [tex]\dfrac{-1}{3}[/tex]
Now, another line is perpendicular to the given line
For perpendicular lines , the products of slope of lines = - 1
Let the slope of another line = M
So, from perpendicular lines condition
m × M = - 1
∴ M = [tex]\dfrac{-1}{m}[/tex]
I.e M = [tex]\frac{-1}{\frac{-1}{3}}[/tex]
So, M = 3
∴ The slope of other line = M = 3 , and the line passing through point (4,3)
Now, Again
The equation of line in slope-intercept form
I.e y = M x + c
Now, satisfying the points on line
So, 3 = 3 × 4 + c
Or, 3 = 12 + c
∴ c = 3 - 12
i.e c = - 9
or, The other line equation = y = 3 x - 9
Hence, The equation of line perpendicular to given line equation and passing through point (4,3) is y = 3 x - 9 . Answer
The 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 and f(x) represents the quarts of oil used. If f(4a) = 80, what is the value of a?
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
The value of a is 4.2

Answer:
73155 is the required 3rd number that will complete the sequence as: 88511, 16351, 73155 , 10251.
Step-by-step explanation:
So, let us consider 88511 and determine the pattern to find the next number and so on to complete the sequence.
Adding the first 2 digits in the number 88511 i.e. 8 + 8 = 16
Subtracting the 3rd digit from the 2nd digit i.e. 8 - 5 = 3
Multiplying the 3rd digit and 4th digit i.e. 5 × 1 = 5
Dividing the 4th digit by the 5th digit i.e. 1 ÷ 1 = 1
Hence, using these steps would get us the number 16351.
So, the next number would be obtained using same steps:
Adding the first 2 digits in the number 16351 i.e. 1 + 6 = 7
Subtracting the 3rd digit from the 2nd digit i.e. 6 - 3 = 3
Multiplying the 3rd digit and 4th digit i.e. 3 × 5 = 15
Dividing the 4th digit by the 5th digit i.e. 5 ÷ 1 = 5
Hence, using these steps would get us the number 73155.
So, the next number would be obtained using same steps:
Adding the first 2 digits in the number 73155 i.e. 7 + 3 = 10
Subtracting the 3rd digit from the 2nd digit i.e. 3 - 1 = 2
Multiplying the 3rd digit and 4th digit i.e. 1 × 5 = 5
Dividing the 4th digit by the 5th digit i.e. 5 ÷ 5 = 1
Hence, using these steps would get us the final number 10251.
So, from this pattern method, we determine that 73155 will be the 3rd number in the sequence: 88511,16351,?,10251.
So, the complete sequence would be: 88511, 16351, 73155, 10251.

A gym has two membership plans.
The Gold Plan costs 50 dollars per month and 3 dollars per visit.
The Platinum Plan costs 20 dollars per month and 6 dollars per visit.
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
6. 40 adults and 26 kids went to
see a movie for $486.70. At the
same price, another group of 20
1 adults and 31 kids went to see
the same move for $332.45.
How much was an adult ticket
and how much was a kid ticket?
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).

Step-by-step explanation:
Given:
Charlie and his friend Jay went to the fair. They were having a sale and the admission was 25% off.
The regular ticket price was $9.00.
And the tax is 6%.
Now, to find Charlie’s total.
So ,we deduct the 25% off first:
[tex]\$9.00-25\%\ of\ \$9.00[/tex]
[tex]=9-\frac{25}{100} \times 9[/tex]
[tex]=9-\frac{225}{100}[/tex]
[tex]=9-2.25[/tex]
[tex]=\$6.75.[/tex]
Now, including tax :
[tex]\$6.75+6\%\ of\ \$6.75[/tex]
[tex]=6.75+\frac{6}{100} \times 6.75[/tex]
[tex]=6.75+0.06\times 6.75[/tex]
[tex]=6.75+0.405[/tex]

If my rent is 2795 a month, I agree to pay 75 more than my roommate how much do I owe and how much does my roommate owe
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

A jumbo size 90 ounces drink at a certain gas station has 890-calories. How many calories are there in a 14 ounce drink
To find the calories in a 14 ounce drink, we first determine the calorie content per ounce from a 90 ounce drink. We find it to be about 9.89 calories per ounce. Multiplying this by 14 gives us approximately 138.46 calories in a 14 ounce drink.
Explanation:To find the calories in a 14 ounce drink, we need to first determine the calorie content per ounce in the 90-ounce drink. This is found by dividing the total calories (890) by the total ounces (90). The number we get from this division (calories per ounce) can then be multiplied by the ounces in the smaller drink (14) to get the number of calories in that drink.
First, divide 890 calories by 90 ounces to find the number of calories per ounce. 890 ÷ 90 = 9.89 calories/ounceNext, multiply this number by the number of ounces in the smaller drink. 9.89 * 14 = 138.46 calories.Therefore, a 14 ounce drink from this gas station would have approximately 138.46 calories.

Round your answer to the nearest whole number.
1) 155.91 grams would be left after 10 years
2) The population would be 376,478 in 2040
Step-by-step explanation:
The form of the exponential function is [tex]y=a(b)^{x}[/tex] , where
a is the initial amount (y at x = 0)b is the growth/decay factorb = 1 + r, where r is the rate of growthb = 1 - r, where r is the rate of decay1)
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
∴ y = 155.91
155.91 grams would be left after 10 years
2)
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
- Round it to the nearest whole number
∴ y = 376,478
The population would be 376,478 in 2040

The city of Toronto’s population rose from 2,000,000 to 4,500,000 in the last twenty years of the twentieth
century. What was the annual average percentage increase in population for that period?
(a) 2.5% (b) 22.5% (c) 11.25% (d) 225% (e) none of these
Answer:
E
Step-by-step explanation:
We will first find the percentage increase of 20 years. Then we will divide that by 20 to get the annual average percentage increase.
To get the percentage increase, we will find the increased amount and divide that by original population (2,000,000). Multiply that by 100 to get the percentage.
So,
Increased amount = 4,500,000 - 2,000,000 = 2,500,000
Now the percentage increase:
[tex]\frac{2,500,000}{2,000,000}*100=125[/tex]
So, in 20 years, the percentage increase is 125%
Per Year = 125/20 = 6.25% average per year
No correct answer in the answer choices from A through D, so E is the correct answer, None of These.

The sum of the digits of a three-digit number is 16 .the tens digit is two more than the units digit and the unit digit is triple the hundreds digit .what is the number?
Answer:
286
Step-by-step explanation:
If the three-digit number is xyz, then:
x + y + z = 16
y = z + 2
z = 3x
Substitute the third equation into the second:
y = 3x + 2
Substitute this and the third equation into the first:
x + (3x + 2) + (3x) = 16
7x + 2 = 16
7x = 14
x = 2
y = 3x + 2 = 8
z = 3x = 6
The number is 286.
The three-digit number where the sum of its digits equal 16, the tens digit is two more than the unit's digit, and the unit's digit is triple the hundreds digit is 286.
Explanation:The question involves finding a three-digit number where the sum of the digits is 16, the tens digit is two more than the unit's digit, and the unit's digit is triple the hundreds digit. Let's represent the hundreds digit as 'h,' the tens digit as 't', and the units digit as 'u'. According to the problem, we have three equations:
h + t + u = 16 (sum of the digits)t = u + 2 (tens is two more than units)u = 3h (units is triple hundreds)Substituting the third equation into the first, we get h + (3h + 2) + 3h = 16, which simplifies to 7h + 2 = 16, leading to h = 2. Thus, u = 3h = 6, and t = u + 2 = 8. Therefore, the three-digit number is 286.
For the function y=8−5x, what is the ordered pair when x=7?
Answer:
Ordered pairs are (0,7) , (1,8) , (-1,6) and (-7,0)
Step-by-step explanation:
Answer:
(7, -27)
Step-by-step explanation:
Given y=8-5x and x=7,
We substitute x=7 into the equation y=8-5x.
This would give us y= 8-5(7) and can be further sinplified to y= 8-35 = -27.
Ordered pair refers to 2 numbers that come in a pair to fulfil an equation in the form of (x, y).
