The number y of perfume bottles in storage after x months is represented by the equation y=-20x+460 . Graph the equation.
Answers
The graph of the linear equation can be seen in the image at the end.
How to graph the linear equation?Here we have the following linear equation:
y = -20*x + 460
To graph the line, we need to find two points on the line, then graph these, and graph a line that connects them.
To get the points, we need to evaluate the linear equation in two values of x.
if x = 0
y = -20*0 + 460
y = 460
if x = 10
y = -20*10 + 460
y = -200 + 460
y = 260
So we have the points (0, 460) and (10, 260), then the graph of the line is:

Answers
The greatest numbers of these rectangles that can be cut from a piece of paper with width 24 and length 60 is 360 which is option D.
Given:
A rectangle with integer side length has perimeter 10.
If the perimeter of rectangle 2(l+b) = 10
l+b = 10/2
l+b = 5.
Two choices:
1. 2 * 3 rectangle of area 6
2. 1 * 4 rectangle of area 4
The piece of paper has area 24×60 = 1440
This can be divided into rectangles with sides 2×3:
= 24/2 * 60/3
= 12*20
= 240
It can be divided into rectangles with sides 1×4:
= 24/1 * 60/4
= 24*15
= 360
Therefore the greatest numbers of these rectangles that can be cut from a piece of paper with width 24 and length 60 is 360 which is option D.

39.7 consumers believe that cash will be obsolete in the next 20 years. assume that 6 consumers are randomly selected. find the probability that fewer than of the selected consumers believe that cash will be obsolete in the next 20 years.
Answers
The probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years is ;
Pr(C & fewer than 3) = 0.1985
What is probability?
Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.
Here, we are required to find the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years.
Let Pr(C) be the number of consumers who believe that cash will be obsolete in the next 20 years.
Therefore, since 39.7% believe so,
Pr(C) = 39.7/100 = 0.397
If 6 consumers are selected randomly, the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years will be;
Probability of 2 out 6 to believe so or Probability of 1 out of 6 to believe so.
Pr(2/6) + Pr (1/6)
Therefore the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years is;
Pr (fewer than 3) = (2/6) + (1/6)
Pr (fewer than 3) = 3/6
Therefore, the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years is ;
Pr(C) × Pr (fewer than 3)
i.e 0.397 × (3/6) = 0.1985
Therefore, the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years is ;
Pr(C & fewer than 3) = 0.1985

If the interest for 4 years on rupees 350 be Rs 112,find the rate percent. In what time will rupees 800 amount to rupees 1120 at the same rate of interest?
Answers
Using Simple Interest formula ,
The rate percent on amount of Rs.300 is 5.5 .
At same rate, R = 5.5 the principle 800 will be Rs1120 in next 7 years .
In first case we have given that ,
principle = Rs.350
time = 4 years
Amount = Rs 1120
simple interest = 1120-350 = Rs.770
let rate of interest be R% .
Using the formul of simple interest
S.I = P×R×t /100
=> 770 = 350×4×R/100
=> R = 5.5 %
In Second case , rate of interest is same as in first case. So,
Amount = Rs. 1120
Principle = Rs. 800
rate of interest (R)= 5.5
Again simple interest formula Used:
Simple Interest = (P × R × T)/100
Simple interest = 1120 - 800 = Rs. 320
Simple Interest = (P × R × T)/100
⇒ 320 = 800×5.5 ×T/100
=> T = 7.27 ~ 7
∴ In the given principle Rs 800 with same rate of interest will be 1120 in 7 next years .

The slope intercept form of equation of required line is
[tex]y = \frac{3}{2}x + \frac{1}{2}[/tex]
What is equation of line in slope intercept form?
The most general form of equation of line in slope intercept form is given by y = mx + c
Where m is the slope of the line and c is the y intercept of the line.
Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.
If [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by
m = [tex]tan\theta[/tex]
The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.
The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.
Here,
Slope of the line = 1.5
The line passes through (21, 32)
Equation of required line =
[tex]y - 32 = 1.5(x - 21)\\y - 32 = \frac{3}{2}(x - 21)\\2y - 64 = 3x - 63\\2y = 3x - 63 + 64\\2y = 3x + 1\\y = \frac{3}{2}x + \frac{1}{2}[/tex]

Answers
30 cars of the delivery company use petrol.
According to the question,
We have the following information:
A delivery company has a total of 160 cars and vans.
The number of cars: the number of vans = 3:7
1/8 of the cars use electricity.
25% of the cars use diesel and rest use petrol.
Let's take the number of cars to be 3x and the number of vans to be 7x.
3x+7x = 160
10x = 160
x = 160/10
x = 16
Number of cars = 3*16
Number of cars = 48
Now, cars that use electricity:
1*48/8
6 cars
Cars that use diesel:
25*48/100
12 cars
Cars that use petrol:
Total number of cars-(number of cars that use electricity and diesel)

Answers
The cost of a box of pasta is $2. 64, then what will you be charged for pasta this week is $1,125.
Define cost.The average cost, or how much it generally costs to produce a unit, can be discovered using the cost function. The average cost function is defined as A(x)=C(x)x, where x > 0. The average cost per unit is calculated by dividing the total cost by the number of units produced.
Given,
Your ending inventories this week for pasta were 35, 41, 32, 19, and 47 boxes. You par value is 120 and a supplier comes each night.
Par level = [(120 - 35) + (120 - 41) + (120 - 32) + (120 - 19) + (120 - 47)]
Par level = [85 + 79 + 88 + 101 + 73]
Par level = 426 units.
Charges = par level × cost
Charges = 426 × 2.64
Charges = 1,124.64

She can see the horizon till 2.604 meters when the person is standing at a height of 5.76 meters above sea level.
Given that,
If a person can see d kilometers into the distance from her eye level, which is h meters above sea level, then d=3.57 √h. Let's say the person is standing at a height of 5.76 meters above sea level.
We have to find she can see the horizon, but how far.
The SI unit of length is the meter. In addition to meters, length can also be expressed in other units like centimeters, inches, feet, and yards.
So,
d=h
3.57 √h= 5.76 meters
Divide both sides by 3.57
√h= 5.76 meter/ 3.57
√h=1.614
