Write an equation of the line that passes through (3,2) and is perpendicular to the line y= 1/3x-3
Answer:
y = - 3x + 11
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{1}{3}[/tex] x - 3 ← is in slope- intercept form
with slope m = [tex]\frac{1}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3, then
y = - 3x + c ← is the partial equation
To find c substitute (3, 2) into the partial equation
2 = - 9 + c ⇒ c = 2 + 9 = 11
y = - 3x + 11 ← equation of perpendicular line
Nikki used the calculations shown to determine whether a carton of 12 eggs or a carton of 18 eggs was the better buy.
A carton of 12 eggs cost $2.39, and a carton of 18 eggs cost $3.39.
Unit price of the 12-egg carton = ($2.39)(12 eggs) = $28.68 per egg
Unit price of the 18-egg carton = ($3.39)(18 eggs) = $61.02 per egg
The 12-egg carton has the lower unit cost, so it is the better buy.
She is right, however her explanation is wrong.
In order to find the unit price, you need to divide the amount by the cost.
You will then see that 12 divided by 2.39 < 18 divided by 3.39.
The smaller unit price is obviously the better buy.
The sales tax on clothing that cost $24 is $1.68. How much would sales tax be on clothing that cost $96?
Answer:
$6.72
Step-by-step explanation:
1.68 is 7% of 24, so there is a 7% tax.
96x.07= 6.72
Answer: The sales tax would be 6.72
Step-by-step explanation: 24 is 1/4 of 96 so that means that you have to multiply the sales tax number by 4 and 1.68 x 4 = 6.72
VSpeeding A trucker handed in a ticket at a toll booth showing that in 2 h she had covered 159 mi on a toll road with speed limit 65 mph. The trucker was cited for speeding. Why
Answer:
The trucker was cited for speeding because his speed was above that of the speed limit of the toll road by 14.5mph
Step-by-step explanation:
Step 1
We calculate the speed of the trucker
Speed = Distance(miles)/Time(hours)
Distance = 159 miles
Time = 2 hours
Speed = 159 miles/2 hours
Speed = 79.5 miles per hour = 79.5 mph
From the question, we are told that: that toll road has a speed limit of 65mph
Step 2
We calculate the difference
= 79.5 mph - 65 mph
= 14.5 mph
Hence, the trucker was cited for speeding because his speed was above that of the speed limit of the toll road by 14.5mph

Y= 8x +3 What is the slope and y-intercept of the equation? Slope = 8; y-intercept = (3, 0) Slope = 3; y-intercept = (0, 8) Slope = -8; y-intercept = (0, 3) Slope = 8; y-intercept = (0, 3)
Answer:
Slope = 8 Y-intecept = (0, 3)
Step-by-step explanation:
Slope-intercept form: y = mx + b
m = slope
b = y intercept value
y = 8x + 3
m = 8
y = 3
A student has $78 in his checking account. If the student spends $12 on lunch, which number could be combined with the amount left in the account to make zero? –90 –78 –66 –12
Given:
A student has $78 in his checking account.
The student spends $12 on lunch.
To find:
The number that could be combined with the amount left in the account to make zero.
Solution:
We have,
Amount in account = $78
Money spend on lunch = $12
Remaining amount = Amount in account - Money spend on lunch
= $78 - $12
= $66
Remaining amount is $66. So, -66 could be combined with the amount left in the account to make zero.
[tex]66+(-66)=66-66=0[/tex]
Therefore, the correct option is C.
Answer:
c

henry has his own dog washing business. his current business model charges by the weight of the dog
Incomplete question. I provided an explanation about the term, "business model."
Explanation:
Usually, when mention is made of the term business model it simply refers to the decided way a business plans to make profits.
In other words, it includes information about services or products to be offered by the business in other to keep the business alive, but not just been alive but to continue growing profit-wise.
Hence, we can say, Henry's business model should contain information about the dog charges which would be profitable to his business.
Which fraction is equivalent to eight twelfths?
Answer:
2/3
Step-by-step explanation:
Pretty simple to find. Divide both the top and the bottom by 4, and see that it makes 2/3. Easy way to figure out any of these is just to simpliy them. Like 10/12 would equal 5/6

The perimeter of a rectangular room is 52 feet. The length is 2 more than the width. What is the width of the room?
A. 10 feet
B. 14 feet
C. 13 feet
D. 12 feet
Answer:
10
Step-by-step explanation:
i think its 10 maybe cuz if u see
the perimeter of a rectangular room is 52 feet. right?
then then height is 2 more than the width. what is the width of the room? so am I right copying the question? yes the question is right copied ok!
now see when u subtract 2 from 12 it gives u 10 and length i as 2 more than the width so maybe 10

how to multiply and add number subtracting them and equating them
Answer:
Over time, mathematicians have developed a set of rules called the order of operations to determine which operation to do first. The rules are: Multiply and divide from left to right. Add and subtract from left to right.
Step-by-step explanation:
Order of operations tells you to perform multiplication and division first, working from left to right, before doing addition and subtraction. Continue to perform multiplication and division from left to right. Next, add and subtract from left to right.
Answer:

Which linear equation can be used to represent a line perpendicular to Line W passing through point (-3,-2)?
line on graph is x=8 Help please
Answer:
D) y = -2
The equation of the perpendicular line to the given line is y = -2
Step-by-step explanation:
Explanation:-
Given point (-3,-2)
In graph the equation of line x = 8 ( parallel to y- axis )
1 x + o y - 8 =0
The equation of the perpendicular line to the given line
b x - a y + k =0
o x - 1 y + k =0 ...(i)
The equation (i) is Paases through the point ( -3,-2)
0 ( -3) -1(-2) + k =0
2 + k =0
k = -2
∴The equation of the perpendicular line to the given line is
put k = -2 in equation (i)
o x - 1 y + k =0
- y +(-2) =0
- y = 2
y = -2
Final answer:-
∴The equation of the perpendicular line to the given line is y =-2

A telephone poll of an SRS of 1234 adults found that 62% are generally satisfied with their lives. The announced margin of error for the poll was 3%. Does the margin of error account for the fact that some adults do not have telephones
Answer:
No. The margin of error only includes sampling variability.
Step-by-step explanation:
The margin of error would be considered for the sampling error
In the case when some adults does not have telephones so it is called as error selection bias this is not a sampling error
The selection bias, unresponse bias and the response would be the examples of an error but it is not a sampling errors
So there is no margin of error as it only involved the variability in the sampling
Dan rolls a fair dice and flips a fair coin. What is the probability of obtaining an even number and a head
Answer: 1/4
Step-by-step explanation:
A die has 6 figures which are 1, 2, 3, 4, 5 and 6. There are 3 even numbers which are 2, 4 and 6. A coin has 2 outcomes which are head or tail.
The probability of getting an even number is 3/6 = 1/2.
The probability of getting a head is 1/2.
Therefore, the probability of obtaining an even number and a head will be:
= 1/2 × 1/2
= 1/4
Suppose that an individual has a body fat percentage of 15.9% in weighs 168 pounds how many pounds of his weight is made up of fat round your answer to the nearest 10th
Answer:
26.7pounds
Step-by-step explanation:
Suppose that an individual has a body fat percentage of 15.9% in weighs 168 pounds
This is calculated as:
Pounds of his weight that is made up of fat is calculated as
Body fat percentage × Body weight in pounds
= 15.9% × 168 pounds
= 15.9/100 = 168 pounds
= 26.712 pounds
Approximately to the nearest tenth = 26.7 pounds
