Lin is reading a 47-page book. She read the first 20 pages in 35 minutes. Rounding to the nearest minute, how long will it take Lin to finish the entire book?
Answer: 82.25 minutes
Step-by-step explanation:
First convert the minutes she took to hours. This would be:
= 35/60
She is reading at a speed of 20 pages per 35/60 hours.
To finish 47 pages therefore, she will take:
= (47 * 35/60) / 20
= 1.37083 hours
Converted to minutes that would be:
= 1.37083 * 60 mins
= 82.25 minutes

Step-by-step explanation: Since the equation of this line is written in
slope-intercept or y = mx + b form, its slope or m is represented by the
coefficient of the x term which in this case is 8/5.
It's y-intercept or b is represented by
the constant term which in this is -5.
To graph the line, start with the y-intercept of -5.
So go down 3 units on the y-axis, plot a point at (0, -3).
From there, take your slope of 8/5, so rise 8 units
and run 5 units the right which should leave you at (5, 3).
Graph the line through those points.

Answer: x = 4 and y = -3
Step-by-step explanation:
2x + 4y = -4
2x = -4 - 4y
x = -2 - 2y
Now that we have solved the first equation for x, we plug (-2 - 2y) into the other equation in place of x and then solve for y.
3(-2 -2y) + 5y = -3
-6 - 6y + 5y = -3
-y = 3
y = -3
Now that we know y, we plug it into the original equation and solve for x.
2x + 4(-3) = -4
2x + -12 = -4
2x = 8
x = 4
You can check the answer by plugging both x and y into either of the original equations.
Solve each compound inequality. Graph your solutions.
5 + m > 4 or 7m< -35
Answer:
Solving the inequality [tex]5 + m > 4\: or\: 7m< -35[/tex] we get [tex]\mathbf{m>-1\:or\: \:m<-5}[/tex]
The graph of the inequality is shown in figure attached.
Step-by-step explanation:
We need to Solve each compound inequality [tex]5 + m > 4\: or\: 7m< -35[/tex]
Solving the inequalities
For solving compound inequalities we solve both inequalities simultaneously and find the value of m.
For solving 5+m > 4, we subtract 5 from both sides.
While solving 7m < -35, we divide both sides by 7 to get value of m
Applying these functions we get:
[tex]5 + m > 4\: or\: 7m< -35\\m>4-5\:or\:m<\frac{-35}{7}\\m>-1\:or\:m<-5[/tex]
So, solving the inequality [tex]5 + m > 4\: or\: 7m< -35[/tex] we get [tex]\mathbf{m>-1\:or\: \:m<-5}[/tex]
The graph of the inequality is shown in figure attached.
Carlos wants to rent a car for the particular car you on gentle rental charges 185 per week plus $0.25 per mile driven rental charges a flat fee of 275 per week what is the number of miles driven so that rented from dental rental cause carlos less than renting from rental giant
Answer:
The indifference point is 360 miles.
Step-by-step explanation:
Giving the following information:
Rental 1:
Total cost= 185 + 0.25*x
x= miles driven
Rental 2:
Total cost= $275
Now, we need to equal both formulas and isolate x:
185 + 0.25x = 275
0.25x = 90
x= 90/0.25
x= 360
The indifference point is 360 miles.

Write an equation of the line that passes through the point (2,3) and is perpendicular to the line x = -1
Answer:
y = 3
Explanation:
Any equation of a line that is written as x = # (meaning x equaling whatever number) is vertical on the graph. Therefore, x = -1 is a vertical line. And since x equals -1, all the points on the graph must have an x-value of -1.
We need to find a line that is perpendicular to it - and what would be perpendicular to a vertical line would be a horizontal line. Horizontal lines are represented by the equation y = # (meaning y equaling whatever number). Whatever number is written there is the y-value of all the points the horizontal line intersects.
We know that the line has to pass through (2,3). Therefore, take the y-value of that point - which is 3 - giving us y = 3.

Find -0.5D D=[18. 16] [-14 -6]
Options are: A. [9 8] [-14 -6] B. [9 8] [7 3] C. [9. 8] [-7 -3] D. [-9 -8] [7 3]
Answer:
The correct answer is Option D: [-9 -8] [7 3]
Step-by-step explanation:
Given that
D = [18 16][-14 -6]
We have to find -0.5D
In order to find the required values of D we only have to multiply the individual elements with -0.5, this might change the signs of elements and reduce the magnitude.
So,
[tex]-0.5D = [-0.5*18\ \ -0.5*16][-0.5*-14\ \ \ -0.5*-6]\\-0.5D =[-9\ \ \ -8][7\ \ \ 3][/tex]
Hence,
The correct answer is Option D: [-9 -8] [7 3]
The length and width or a rectangular courtyard is 40 feet and 30 feet, respectively. In order to make the courtyard larger, an additional 15 feet is being added to the width
Answer:
The new area is 1800feet^2
Step-by-step explanation:
Step one:
Given data
The length and width or a rectangular courtyard is 40 feet and 30 feet
we can calculate the area of the courtyard as
Area= 40*30
Area= 1200 feet^2
when the extra 15 feet is added to the width
the new width is= 30+15= 45feet
The new area is
Area= 40*45
Area= 1800 feet^2
in all the area will increase by 1800-1200= 600feet

if the tire pressure gauge is showing the reading 8% higher, the what is the actual pressure if the reading is 39.42?
Answer:
The actual pressure is 36.50
Step-by-step explanation:
Given that:
Tire pressure reading = 8% higher
Reading = 39.42
As 100% will be the actual reading.
New reading = (100+8)% = 108%
Let,
x be the actual pressure of the tire
108% of x = 39.42
[tex]\frac{108}{100}x=39.42\\1.08x = 39.42[/tex]
Dividing both sides by 1.08
[tex]\frac{1.08x}{1.08}=\frac{39.42}{1.08}\\x=36.50[/tex]
Hence,
The actual pressure is 36.50

A company that makes hair-care products had 4,000 people try a new shampoo. Of 4,000 people, 24 had a mild allergic reaction. What percent of the people had a mild allergic reaction?
Please help me!!!
the answer is 0.6% i think hope this helps
Answer:
0.6%
Step-by-step explanation:
[tex]\frac{24}{4000}[/tex] = 0.6%
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 4000 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 4000, so we can write it down as 100%=4000.
4. We know, that x% equals 24 of the output value, so we can write it down as x%=24.
5. Now we have two simple equations:
1) 100%=4000
2) x%=24
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=4000/24
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 24 is what percent of 4000
100%/x%=4000/24
(100/x)*x=(4000/24)*x - we multiply both sides of the equation by x
100=166.666666667*x - we divide both sides of the equation by (166.666666667) to get x
100/166.666666667=x
0.6=x
x=0.6
now we have:
24 is 0.6% of 4000

slope = 4
y intercept = 0
====================================================
Explanation:
Two points on this line are (8,32) and (12,48)
Apply the slope formula to get
m = (y2-y1)/(x2-x1)
m = (48-32)/(12-8)
m = 16/4
m = 4
The slope is 4.
Use a point like (x,y) = (8,32) and the slope we found to determine the y intercept b
y = mx+b
32 = 4*8+b
32 = 32+b
32-32 = 32+b-32 ... subtract 32 from both sides
0 = b
b = 0
------------------
We found that m = 4 is the slope and b = 0 is the y intercept
We go from y = mx+b to y = 4x+0, which simplifies to y = 4x
In short: the y coordinate is 4 times that of the x coordinate.
For instance, if x = 16, then
y = 4x = 4*16 = 64
Which leads to the point (16,64)
Note: the slope of 4 means it costs 4 dollars per gallon. We can think of this as the unit rate, or rate of change.
Answer:
y = 4x
Step-by-step explanation:
The relation is proportional ⇒ y = kx , k = [tex]\frac{y}{x}[/tex]
~~~~~~~~~~
(8, 32)
(12, 48)
(16, 64)
k = 32 ÷ 8 = 4
y = 4x
