What is the slope of a line that is perpendicular to the line whose equation is 8y−5x=11?
Ill give someone brainlist
9514 1404 393
Answer:
-8/5
Step-by-step explanation:
When you solve for y, the slope of the line is the x-coefficient. For the given line, that is ...
8y = 5x +11 . . . . . add 5x
y = 5/8x +11/8 . . . . divide by 8
The given line has a slope of 5/8. The perpendicular line will have a slope that is the opposite of the reciprocal of this:
-1/(5/8) = -8/5 . . . . slope of perpendicular line
Answer:
The slope of the perpendicular line will be -8/5, or -1.6
Step-by-step explanation:
First we need to rearrange the equation to show the slope, putting in the format y = sx + c:
[tex]8y - 5x = 11\\8y = 5x + 11\\y = \frac{5}{8}x + \frac{11}{8}[/tex]
So the given line has a slope of 5/8.
A line perpendicular to that will have a negative reciprocal of that slope, so it's slope will be -8/5.

Sarah wants to leave a tip of 15%. Her bill before the tip is $23.00. How much should she leave for the tip ? show your work.
Answer:
$26.45.
Step-by-step explanation:
First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.
Second, you need to find out what 15% of your $23.00 meal cost is.This is always done by multiplying 0.15 by $23.00, or
0.15 x $23.00=$3.45.
So, the amount of tip you are going to leave is $3.45.
This makes the total cost of your meal (to write on your charge slip or other payment)
$23.00 + $3.45 = $26.45.

Samiya bought a tree 3 inches long. Each year, the tree expected to grow 5 inches. How long (How many years) it takes the tree to reach the height of 8 feet (or 96 inches)? Let \large y be number of years it takes to reach 96 inches tall;
Answer:
19 years
Step-by-step explanation:
Initial height of tree when Samiya bought the tree = 3 inches
Growth in the height of tree every year = 5 inches
Number of years = [tex]y[/tex]
Growth in the height of tree in [tex]y[/tex] years = 5 inches multiplied by number of years
Growth in the height of tree in [tex]y[/tex] years = 5[tex]y[/tex] inches
To find:
Number of years taken by the tree to be 8 ft or 96 inches.
Solution:
The equation for height of tree after [tex]y[/tex] years can be written as:
3 + 5[tex]y[/tex] which is to be compared with 96 inches.
Therefore, the equation is:
[tex]3 + 5y = 96\\\Rightarrow 5y=93\\\Rightarrow y \approx 19[/tex]
Therefore, it will take 19 years for the tree to reach a height of 96 inches.
Victoria moved into a new apartment and called to install her cable. They told her they charge $45 to install the cable box and $60 for each month of service. Which equation represents how much victoria will owe after x months?
Answer:
[tex]y=45+60x[/tex]
Step-by-step explanation:
Step one:
given data
The charge is $45 to install the cable box and $60 for each month of service
Required
The linear expression for the situation.
Step two:
let the number of months be x and let the total charges be y
Hence the expression for the total charges is
[tex]y=45+60x[/tex]
Sydney has a bag of stuffed animals containing, 1 elephant, 4 bears, 3 cats, and 2 dogs. If she randomly selects 1 stuffed animal from the bag, places it on her bed and then selects another animal. What is the probability that she chooses a bear both times?
Answer:
2/15
Step-by-step explanation:
Step one:
given data
sample space
1 elephant,
4 bears,
3 cats, and
2 dogs.
sample size= 1+4+3+2= 10
Required:
By selecting without replacement, the probability that she chooses a bear both times
Step two:
the first event= Pr(bear)= 4/10= 2/5
the second event, the sample size is now 9 and the number of bears is now 3
Pr(bear)= 3/9= 1/3
Hence, the probability that she chooses a bear both times
= 2/5*1/3
=2/15

A couple of college students get the idea to open a snack stand at the regatta festival this summer. The students sell delicious soft pretzels. They pay the city $648 to set up their stand for the entire regatta. They also figure the cost for dough, coarse salt, and other things they need is $0.20 per pretzel. They sell each pretzel for $2.90. a. What is the cost and the income obtained from selling forty pretzels?
b. If the income from selling the pretzels was $261, how many pretzels did they sell?
c. How many pretzels must they sell to break even, according to the algebraic model?
Answer:
a) The cost of producing 40 pretzels is $656
The income for selling 40 pretzels is $116
b) They sold 90 pretzels
c) They must sell 240 pretzels to break-even
Step-by-step explanation:
Linear Models
A linear model is an equation that describes a relationship between two quantities that have a constant rate of change.
One of the most-used equations of linear models is the slope-intercept form, written as:
y = mx + b
Where m is the slope of the graph of the line and b is the y-intercept.
The total cost of producing soft pretzels is divided into two parts:
* A fixed cost of $648 to set up their stand for the entire regatta.
* A variable cost of $0.20 per each pretzel.
Thus, the cost function can be written as:
C(x)=648+0.20x
Where x is the number of pretzels produced.
The students sell each pretzel for $2.90. This means the income (revenue) function for selling x pretzels is:
R(x)=2.90x
a) The cost of producing x=40 pretzels is:
C(40)=648+0.20*40
C(40)=648+8
C(40)=656
The cost of producing 40 pretzels is $656
The income is:
R(40)=2.90*40=116
The income for selling 40 pretzels is $116
b) If the income from selling pretzels is R=$261, then:
2.90x=261
Solving for x:
x = 261/2.90
x = 90
They sold 90 pretzels
c) To break-even the total cost and the income must be equal:
2.90x=648+0.20x
Subtraction 0.20x:
2.70x=648
Dividing by 2.70:
x = 648/2.70
x = 240
They must sell 240 pretzels to break-even

A map has a scale of 2 cm = 25 km. Two cities are 15 centimeters apart on the map. What is the actual distance between the cities?
Answer:
187.5 km
Step-by-step explanation:
For every 2cm there is 25km, So 2cm/25km. Now you are given 15cm, and you need to find the actual distance in km. Set up the fraction 2cm/25km=15cm/Xkm and solve for X using cross multiplication as follows:
2x=25(15), so 2x=375, X=187.5 km.

Tom sells Tvs at an electronic store. He gets paid $100 for each TV he sells. He also gets a $500 bonus each month for selling above a certain amount. Tom wants to make a least $1,500 this month. How many TVs will he have to sell if he gets $500 bonus?Chose the inequality that best represents this situation.
A. 100t+500≥1,500
B. 100t+500≤1,500
C. 100t+500<1,500
D. 100+500t≥1,500
Explain your reasoning and solve the inequality:
Answer:
The answer is A
Tom will have to sell at least 10 TVs to get the bonus and to get $1,500
Step-by-step explanation:
Total: The same or above 1500
Tom gets paid 100 for each TV = 100t
He can get a 500 bonus by selling a certain amount = 500
100t + 500 ≥ 1,500
100t + 500 - 500 ≥ 1500 - 500
100t ≥ 1000
100t ÷ 100 ÷ 1000 ÷ 100
t ≥ 10
Tom will have to sell at least 10 TVs to get the bonus and to get $1,500
