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]

[tex]5x-4x=56[/tex]

[tex]x =56[/tex] mph

Step-by-step explanation:

The equation x + |y| = y + |x| that contains the absolute values of x and y, is satisfied when the values of x and y are given by the iniquities;

The absolute value or modulus of a real number gives its non negative value irrespective of the sign (positive or negative) of the number.

The given equation is presented as follows;

x + |y| = y + |x|

The possible values of x and y are;

-10 ≤ x ≤ 10 and -10 ≤ y ≤ 10

Collecting the absolute values of the equation on one side gives;

|y| - |x| = y - x, which gives;

+y - +x = y - x

The equation is therefore satisfied when both x and y are larger than zero.

Therefore, x + |y| = y + |x|, gives;

0 ≤ x ≤ 10, and 0 ≤ y ≤ 10

The bacteria present at t=37 minutes is found to be 8.40, with no change in growth rate.

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

As a result, the bacteria that will be present in t=37 minutes is found to be 8.40 with no change in growth rate.

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.

In the question ,

it is given that

Money deposited by Manvita =  Rs 5000 .

Money withdrawn by Manvita = Rs 3748 .

Since , amount deposited is a positive integer ,

So, the amount withdrawn will be a negative integer

Balance in Manvita's account = Money deposited + Money Withdrawn

Substituting the values , we get

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.

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.
