Based on the weight of the plastic to the weight of the paper, the ratio of plastic to paper in the simplest form is 6 : 1
How to find the ratio?To find the ratio of plastic to paper, there is a need to convert the weights such that they have the same units.
Assuming we convert the plastics to grams, the number of grams of plastic would be:
= 3 kg x 1,000 grams per kg
= 3,000 grams
The ratio then would be:
3,000 grams of plastic : 500 grams of paper
To get to the simplest form, divide both sides by 500:
3,000 / 500 : 500 / 500
6 : 1

41.4 is what percent of 92?
Answer: 45
41.4 is 45 percent of 92
Answer: 45%
Step-by-step explanation:
Solution for 41.4 is what percent of 92:
41.4:92*100 =
(41.4*100):92 =
4140:92 = 45
Now we have: 41.4 is what percent of 92 = 45
Question: 41.4 is what percent of 92?
Percentage solution with steps:
Step 1: We make the assumption that 92 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: 100%=92.
Step 4: In the same vein, x%=41.4.
Step 5: This gives us a pair of simple equations:
$100%=92(1).
$x%=41.4(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100%/x%= 92/41.4
Step 7: Taking the inverse (or reciprocal) of both sides yields
x%/100% = 41.4/92
-> x=45%
Therefore, 41.4 is 45% of 92.

Daniel walks at a speed of 4 miles per hour. Daniel leaves his house at 1:00 p.m. and walks toward a playground exactly 2 miles away.
Daniel's mother plans to walk to the playground too. She walks at a speed of 6 miles per hour.
At what time should Daniel's mother leave the house to arrive at the playground at the same time as Daniel?
Daniel's mother should leave the house at 1:10 P.M. to arrive at the playground at the same time as Daniel.
According to the question,
We have the following information:
Speed of Daniel = 4 miles per hour
So, it means that Daniel covers 4 miles in 1 hour.
1 hour = 4 miles or 4 miles = 1 hour
1 mile = 1/4 hour
1/4 hour means (60/4) minutes or in other words 15 minutes.
Now, Daniel will cover 1 mile in 15 minutes.
So, the time taken by Daniel to cover 2 miles = 15*2 minutes
Time taken by Daniel to cover 2 miles = 30 minutes
So, Daniel will reach the playground at 1:30 P.M.
Now, speed of Daniel's mother = 6 miles per hour
So, we have:
6 miles = 1 hour
6 miles = 60 minutes
1 mile = 60/6 min
1 mile = 10 min
So, to cover 2 miles, Daniel's mother will take (2*10) minutes or 20 minutes.
Now, Daniel will reach the playground at 1:30 P.M.
So, Daniel's mother should start from her house at 1:10 P.M.
Hence, Daniel's mother should start at 1:10 P.M.

Graph the image of rectangle CDEF after a translation 4 units left and 9 units up.
The graph of the image of rectangle CDEF after a translation 4 units left and 9 units up is as shown below.
In this question, we have been given the image of rectangle CDEF.
The coordinates of rectangle CDEF are:
C = (-6, -6)D = (-2, -6)E = (-2, 0)F = (-6, 0)
The rectangle CDEF is a translated 4 units left and 9 units up.
When rectangle CDEF is a translated 4 units left then the coordinates of rectangle would be,
C' = (-10, -6)
D' = (-6, -6)
E' = (-6, 0)
F' = (-10, 0)
Then rectangle C'D'E'F' is translated 9 units up then the coordinates of rectangle would be,

Examples of permutation matrices are the identity matrices with a permutation in rows. Permutation matrices are invertible and the inverse is a permutation matrix as well.
A permutation matrix is a square matrix which contains exactly one 1 in each row and all other entries 0.
So a permutation matrix can be obtained by rearranging the rows or columns of an identity matrix. Identity matrix is also a permutation matrix with entry 1 exactly once in each row and all other entries 0.
Example of a permutation matrix:
[tex]\left[\begin{array}{ccc}1&0&0\\0&0&1\\0&1&0\end{array}\right][/tex]
A permutation matrix is invertible because an identity matrix is invertible [since det(I) = 1] and a permutation matrix is just got by exchanging rows or columns which does not change its determinant. So the determinant of a permutation matrix ≠ 0 and hence invertible.
The inverse of a permutation matrix is its transpose itself. The transpose is again a permutation matrix.

A particular bacterium population is found to double the in 20 minutes. If a laboratory culture
begins with a population of P=340 of this bacteria and there is no change in the growth rate, how
many bacteria will be present in t=37 minutes?
Hint: Use equation P = Poekt, where k is the relative growth. Round to two decimal places.
The bacteria present at t=37 minutes is found to be 8.40, with no change in growth rate.
What does population growth exponentially mean?When a population's per capita growth rate remains constant, regardless of population size, exponential growth occurs, causing the population to grow exponentially as the population increases.
Given:
P = 340
It has been discovered that a specific bacterial population doubles in 20 minutes.
k = 2/20 = 0.1
t = 37 minutes
We know that,
P = P₀[tex]e^{kt}[/tex]
340 = P₀([tex]e^{0.1*37}[/tex])
340 =P₀(40.44)
P₀ = 8.40

Trevon left home and traveled toward the recycling plant. Mike left one hour later traveling 14 mph faster in an effort to catch up to him. After four hours Mike finally caught up. Find Trevon's average speed.
The most appropriate choice for speed will be given by-
Average speed of Trevon is 56 mph
What is speed?
The distance travelled by the body per unit time is called speed of the body.
If d is the distance travelled by the body and t is the time taken, then
speed = [tex]\frac{d}{t}[/tex]
Speed is a scalar quantity as the direction is not taken into account.
Here,
Let the average speed of Trevon be [tex]x[/tex] mph
Average speed of Mike = [tex](x + 14)[/tex] mph
Time for which Trevon driven = [tex](4 + 1)[/tex] h
= [tex]5[/tex] h
Time for which Mike driven = [tex]4[/tex] h
By the problem,
[tex]5 \times x = 4 \times (x+14)[/tex]
[tex]5x = 4x+56[/tex]
