Answer:

14 N

Step-by-step explanation:

Let the mass of the box be m.

F = ma → F = 5 x 4.2 = 21 N

When mass = 2.8 kg, let the acceleration is a. For same force:

=> 21 = a x 2.8

=> 21/2.8 = a

=> 7.5 m/s² = a

Answer:

7.5M/s^2

[tex]2\sqrt{2} :1[/tex]

Step-by-step explanation:

This question was linked from another one regarding the lengths of the cubes, you can find it here: https://brainly.com/question/22396279

That question gave you the ratio of the lengths, which is [tex]\sqrt{2} :1[/tex]. Now in geometry, a general rule about solids is that if they are similar, the ratio of their volumes is the cube of the ratio of their edges. In a cube's case, every single cube known to mankind is similar as all the edges are the same length.

So the ratio of volumes would be [tex]\sqrt{2} ^3:1^3[/tex], which can be simplified as [tex]2\sqrt{2} :1[/tex].

The measure of the angle m∠1 is 31 degree and the measure of the angle m∠2 is 106 degree.

When two lines or rays converge at the same point, the measurement between them is called a "Angle."

We have:

m∠4=74° and m∠3=43°

m∠4 + m∠2 = 180

74 + m∠2 = 180

m∠2 = 106 degree

m∠3 + m∠2 + m∠1 = 180  (sum of angles in triangle is 180 degree)

43 + 106 + m∠1 = 180

m∠1 = 31 degree

Thus, the measure of the angle m∠1 is 31 degree and the measure of the angle m∠2 is 106 degree.

Point 2 is 106°

Point 1 is 31°

Bit by bit clarification:

every triangle's total angle is 180

first you 180 - 74 = 106 for angle 2

angle 2 you had to use the angle two total then you add it with angle three like this 106 + 43 = 149 then you do  180 - 149 = 31 will give you your angle one

Answer:

x+y≤15

Step-by-step explanation:

We need to write an inequality that represents the sum of x and y is at most 15. At most in inequality is defined as less than or equal to i.e. ≤.

Sum of x and y means x+y

The inequality becomes,

x+y≤15

Hence, the correct option is (b).

The inequality which represents the sum of x and y is at most 15 is; Choice (b) x+y_<15

According to question;

In essence, the sum of x and y is either equal to or lesser than 15.

Therefore, the inequality is Choice B; x+y_<15

The function representing the number of bacteria present each day is

[tex]\rm f(t) = 2032(0.85)^{t}[/tex] .

A function from a set X to a set Y assigns to each element of X exactly one element of Y.

The set X is called the domain of the function and the set Y is called the codomain of the function

A bacteria population starts at 2032 and decrease by 15% everyday.

a function representing the number of bacteria present each day

[tex]\rm f(t) = 2032(1-.15)^{t}[/tex]

[tex]\rm f(t) = 2032(0.85)^{t}[/tex]

Therefore [tex]\rm f(t) = 2032(0.85)^{t}[/tex] is the correct answer .

First, subtract 4 from both sides of the equation:

6x + 4 (-4) = 22 (-4)

6x = 22 - 4

6x = 18

Next, divide 6 from both sides of the equation:

(6x)/6 = (18)/6

x = 18/6

x = 3

That would be 19! / 10!, which is 33522128640

If to create a CD 9 songs are needed and user have 19 songs then he can create 33522128640 such CD's if solving through permutations.

It is basically an arrangement of objects in a certain order.It is expressed as n[tex]P_{r}[/tex] and it is equal to n!/(n-r)!.

We have been given that user have 19 songs and 1 CD is made from 9 songs so the number of CD's which can be made is basically the number of ways these 9 songs are arranged from 19 songs in CD's. So, the number of CD's will be 19[tex]P_{9}[/tex]=19!/(19-9)!

=19!/10!

=19*18*17*16*15*14*13*12*11*10!/10!

=19*18*17*16*15*14*13*12*11

=335322128640 CD's

Hence 335322128640 CD's can be made from 19 songs by the user.
