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.

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]

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.

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.

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 coordinates of A are (-5, -5).

How to determine the midpoint of a given segment?
The center point of a straight line can be located using the midpoint formula. We can use this midpoint formula to determine the coordinates of the supplied line's midpoint in order to discover its location on a graph. Assuming that the line's endpoints are (x₁, y₁) and (x₂, y₂), the midpoint (a, b) is determined using the following formula:
(a , b) ≡ (((x₁ + x₂)/2), ((y₁ + y₂)/2))

Given, the line segment under consideration is AB as endpoints.
And, the co-ordinate of B is = (6, 1)
Also, the midpoint of segment AB i.e. M is = (0.5, -2)
Let the co-ordinate of A be = (x, y)
Using the available literature and formula, we get
(0.5, -2) ≡ (((x + 6)/2), ((y + 1)/2))
Equating both parts in the given equation,
0.5*2 = x + 6 ⇒ 1 = x + 6 ⇒ x = -5
and, (-2)*2 = y + 1 ⇒ -4 = y + 1 ⇒ y = -5
Therefore, the co-ordinates of A are (-5, -5).

If he gets paid $20 per hour to work at the grocery store and $2 per hour to work at nursery,

Part a

He will earn $449 if he works 13 hours at the grocery store and 9 hours at the nursery

Part b

He will earn 20g + 21n, if he works g hours at the grocery store and n hours at the nursery

The payment at the grocery store per hour = $20

The payment at the nursery per hour = $21

Part a

Number of hours he works at the grocery store = 13 hours

Number of hours he works at nursery = 9 hours

Total pay = 13×20 + 9×21
