Step-by-step explanation:

The minimum force needed to start the box moving is slightly greater than 75 N.

In order for an object to start moving, the force applied to it must be greater than the static friction force. Static friction is the force that acts between two surfaces that are not moving relative to each other, and it opposes any motion between the two surfaces. The static friction force is equal in magnitude to the normal force (the force exerted by the surface the object is resting on) multiplied by the coefficient of static friction between the two surfaces.

In this case, the normal force on the box is 75 N, and the coefficient of static friction between the box and the surface it is resting on is typically between 0 and 1. Therefore, the static friction force is also between 0 and 75 N. The minimum force needed to start the box moving is slightly greater than the static friction force since the static friction force must be overcome in order for the box to start moving.

Peter left Town A around 10 a.m., traveling at an average speed of 84 km/h. William would reach Town B at 1:23 PM.

Firstly, we need to find the distance between Town A and Town B which can be calculated by calculating the distance travelled by Peter

Time taken by Peter = 2PM - 10AM

= 4 hrs

Speed of Peter = 84 km/h

Distance travelled by Peter = speed × time

= 84 × 4

= 336 km

So, the distance between Town A and Town B  = distance travelled by Peter = 336 km.

Now, we will calculate time taken by William.

Speed of William = 70 km / hr

Distance travelled by William = distance between Town A and town B = 336 km

Time taken by William = distance / speed

= 336 / 70 hr

= 4.8 hr

This can b converted into hrs and minutes

4.8 hr = 4 hr + 0.8 × 60

= 4 hr 48 mins

Time William took off = 10 AM - 1hr 25 mins

= 8:35 AM

Now, we will calculate the time William would reach town B.

Time = 8:35 + 4hr 48 mins

= 1:23 PM

I hope it helps ❤️

Answer: A and C

Step-by-step explanation:

Determine the answer by solving for x in each equation.

A. x + 4= 7    subtract 4 from both sides

        -4   -4

   x =  3    

B.   x/9 = 3    multiply both sides by  9  

       x=27

C. 5-x =2   subtract 5 from both sides

    -5    -5

   -1x = -3

   x= 3

D.  8x = 32   divide both sides by 8

    x = 4

E .  x -10 = 7  Add 10 to both sides

          +10  +10

x = 17

A baker makes 90 cakes in a 60-hour week

A baker makes 18 cakes in a 12-hour day.

So, the number of cakes she makes in an hour would be,

18/12 = 1.5 cakes/hour

We need to find the number of cakes she make in a 60-hour week.

Using unitary method we find the required number of cakes,

1.5 * 60 = 90

Therefore, a baker makes 90 cakes in a 60-hour week

Answer:

(B) \(b + 2b - 83 = 259\)

Step-by-step explanation:

We can first create the equation \(b + g = 259\), since we know that there are a total of 259 students in this freshman class.

Now, the amount of girls is 83 less than twice the number of boys, so that is \(2b - 83\).

Now, we can substitute this in the previous equation as g.

Let's assume there are 3 personal checks and individuals

First let's find the recurrence relation for the number of ways these checks can be place in the right envelope

Explanation: Person A has a 1/3 chance of getting the right envelope, person B has a better chance of 1/2 since envelope A is already taken, and finally, person C has a 1/1 chance

Thus, we can also write this as,

Now, to find the recurrence relation for the number of ways these checks can be place in the n envelopes so that no check is in the right envelope, we just need to substrac 1 - P , which is,

Answer:

  134°

Step-by-step explanation:

You want the measure of exterior angle x, given the remote interior angles are 34° and 100°.

The exterior angle of a triangle is equal to the sum of the remote interior angles:

  x = 34° +100°

  x = 134°

__

Additional comment

The sum of interior angles is 180°, and the sum of a linear pair is 180°. If Q is the unmarked third angle of the triangle, you have ...

  34° + 100° + Q = 180° = x + Q

Subtracting Q gives the equation above.

This is a variation of the notion "angles supplementary to the same angle are congruent." Both x and the angle sum are supplementary to Q.

The results of operations between vectors are, respectively:

Case A: u + w = <- 3, - 1>

Case B: - 6 · v = <6, 6>

Case C: 3 · v - 6 · w = <- 21, - 15>

Case D: 4 · w + 3 · v - 5 · u = <39, 4>

Case E: |w - v| = √(4² + 3²) = 5

In this problem we must determine the operations between vectors, this can be done by following definitions:

Vector addition

v + u = (x, y) + (x', y') = (x + x', y + y')

Scalar multiplication

α · v = α · (x, y) = (α · x, α · y)

Norm of a vector

|u| = √(x² + y²)

Case A:

u + w = <- 3, - 1>

Case B:

- 6 · v = - 6 · <- 1, - 1>

(1.985, 15.815)

Step-by-step explanation:

Given that:

Sample size (n) = 20

Standard deviation (s) = 11.986

Mean (m) = 8.9

α = 99%

Using the relation :

Confidence Interval = Mean ± Error

Where ;

Error = Zcritical * standard deviation / sqrt(n)

Zcritical at 99% = 2.58

Hence,

Error = 2.58 * (11.986/sqrt(20))

Error = 2.58 * 2.6801510

Error = 6.91478958

Hence,

Lower boundary = 8.9 - 6.91478958 = 1.98521042

Upper boundary = 8.9 + 6.91478958 = 15.81478958
