Answer:
a) 2 new printers
b) 11 min
Step-by-step explanation:
Given:
5 old printers take 30 min to produce a batch of comic books
4 new printers take 18 min to produce a batch of comic books
.
a) First, we need to find how long does one old and new printer take to produce a batch of comic books:
.
Since 5 old printers take 30 min to do the job, one printer would take 5 times more than this (5 printers work together and they do the job faster than one, that's why we have to multiply):
.
1 old printer does the job in:
5 × 30 = 150 min
1 new printer does the job in:
4 × 18 = 72 min
.
Since one old printer does the job in 150 min, 6 old printers would do this job 6 times faster (that's why we divide):
6 old printers would take:
150 / 6 = 25 min
2 new printers would take:
72 / 2 = 36 min
.
25 < 36
That means, 2 new printers would do this job faster
.
b) In order to find how much less time would this take, we have to subtract:
.
36 - 25 = 11 min

A bag contains 6 red marbles, 4 blue marbles and 7 green marbles. If three marbles are drawn out of the bag, what is the exact probability that all three marbles drawn will be green?
the exact probability of drawing three green marbles from the bag is 0.0735 or approximately 7.35%.
To find the probability of drawing three green marbles from the bag, we need to use the formula for calculating the probability of multiple independent events. The probability of multiple independent events occurring together is the product of the individual probabilities of each event.
Let's first calculate the probability of drawing a green marble on the first draw. We have a total of 6 + 4 + 7 = 17 marbles in the bag, and 7 of them are green. So the probability of drawing a green marble on the first draw is:
P(green on first draw) = 7/17
After we draw a green marble on the first draw, we have 16 marbles left in the bag, including 6 red marbles and 4 blue marbles. Since we don't replace the marble after we draw it, the probability of drawing a green marble on the second draw is:
P(green on second draw) = 6/16
Finally, after we draw a green marble on the second draw, we have 15 marbles left in the bag, including 5 green marbles. So the probability of drawing a green marble on the third draw is:
P(green on third draw) = 5/15
To find the probability of drawing three green marbles in a row, we need to multiply these probabilities:
P(three green marbles) = P(green on first draw) x P(green on second draw) x P(green on third draw)
P(three green marbles) = (7/17) x (6/16) x (5/15)
Simplifying this expression, we get:
P(three green marbles) = (7 x 6 x 5) / (17 x 16 x 15)
P(three green marbles) = 0.0735
Therefore, the exact probability of drawing three green marbles from the bag is 0.0735 or approximately 7.35%.

A family wants to send supplies to a hospital via a suitcase they want to fill it up with as many supplies as possible. Their suitcase height is 5 ft and length 4 ft and width 4 f. Each supply has a base area of 9. And they can put 5120 supplies in the trunk. what is the height of each supply?
Answer:
approximately 0.0018 feet, or about 0.0216 inches.
Step-by-step explanation:
The volume of the suitcase is:
V_suitcase = height x length x width
V_suitcase = 5 ft x 4 ft x 4 ft
V_suitcase = 80 cubic feet
The volume of each supply is:
V_supply = base area x height
We know that the base area of each supply is 9 square feet. Let's assume that the height of each supply is h.
So, the total volume of all the supplies that can be put in the suitcase is:
V_total_supplies = V_supply x number of supplies
V_total_supplies = (9 ft^2 x h) x 5120
We want to find the height of each supply, so we can rearrange the equation above to solve for h:
h = V_total_supplies / (9 ft^2 x 5120)
Substituting the values we know:
h = (80 ft^3) / (9 ft^2 x 5120)
Simplifying, we get:
h = 0.0018 ft
So the height of each supply is approximately 0.0018 feet, or about 0.0216 inches.
A van travels at a constant speed. The distance y in miles tat the van has traveled after x hours is shown in the table below.
The van would have traveled approximately 8 miles of distance after 12 minutes.
To calculate the distance traveled by the van after 12 minutes, we can use the formula:
y = mx
Where m is the rate of travel, and x is the time in minutes.
To find the value of m, we can use the first two data points:
m = (y2 - y1) ÷ (x2 - x1)
m = (8 - 0) ÷ (10 - 0)
m = 8 ÷ 10
m = 4 ÷ 5
Therefore, the formula becomes:
y = (4 ÷ 5) x
Now, we can substitute x = 12 to find the distance traveled after 12 minutes:
y = (4 ÷ 5) × 12
y = 0.8 × 12
y = 9.6
y ≈ 8 miles

Solve 4 x squared equals 5 left parenthesis 4 x minus 5 right parenthesis.
The solution to the equation [tex]4x^2 = 5(4x - 5)[/tex] is x = 5/2."
To solve the equation [tex]4x^2[/tex] = 5(4x - 5), we first simplify the right-hand side by using the distributive property:
Next, we bring all the terms to one side of the equation by subtracting 20x and adding 25 to both sides:
[tex]4x^2 - 20x + 25 = 0[/tex]
This equation is now in the form of a quadratic equation [tex]ax^2[/tex] + bx + c = 0, where a = 4, b = -20, and c = 25. We can solve for x using the quadratic formula:

Chang is building a circular sandbox with a circumference of 31.4 meters. She uses a string tied to a metal stake to trace out a circle in her backyard.
Mr. Chang's string will therefore be about 10 meter long rounded to nearest meter
What exactly is pi?
The proportion of a circle's circumference to its diameter is denoted by the mathematical constant pi (). It cannot be written as a simple fraction since it is an irrational number. Pi is approximately equal to 3.141592, or 3.15.
We must first determine the circle's radius in order to determine the length of Mr. Chang's string.
C = 2πr, where C is the circle's circumference and r is its radius, is the formula for a circle's circumference.
Given that the circle's circumference is 31.4 meters, we can solve for r using the following method:
C = 2r 31.4
=2x3.14xr
= 31.4/(2x3.14)r
= 3.14/6.28r
r = 5
Thus, the circle's radius is roughly 5 meters.
The diameter of the circle, which is twice as long as its radius, will be equal to Mr. Chang's stake because it is in the center of the circle.
Mr. Chang's string will therefore be about 10 meter long rounded to nearest meter

For a rectangle that is 8 inches long, 3 inches on the bottom, and 5 inches on the side, there are a few things you can do.
The perimeter of a rectangle is the sum of the lengths of all four sides.
To calculate the perimeter, add the lengths of the top and bottom sides (8 + 3 = 11) and the lengths of the two side lengths (5 + 5 = 10).
To find the area of a rectangle with an 8-inch long side, a 3-inch bottom side, and a 5-inch side, follow these steps:
Identify the dimensions of the rectangle.
The dimensions are given as 8 inches long, 3 inches on the bottom, and 5 inches on the side.
However, a rectangle only has two different side lengths, so we can assume that the 3-inch measurement is irrelevant.
Confirm the side lengths.
In this case, the side lengths are 8 inches and 5 inches. The 8-inch side is the length, and the 5-inch side is the width.
Calculate the area of the rectangle.
To find the area, multiply the length by the width. In this case, that is 8 inches (length) multiplied by 5 inches (width).

The equation for the new function F(t) is F(t) = 9t - 256/9.
What is function?
In mathematics, a function is a relationship between two sets of elements, called the domain and the range, such that each element in the domain is associated with a unique element in the range. In simpler terms, a function is a set of rules that takes an input value and produces a corresponding output value.
