In a tug-of-war, Team A is pulling to the left with 6 Newtons and Team B is pulling to the right with
4 Newtons. What is the net force?

Answer:

15%

Step-by-step explanation:

Since the problem is to find how much 69 is as a percent if 60 is 100%, we can use a rule of three, simple, direct proportion to do it:

60 = 100%

68 = x

x = 69x100/60

x = 115

That means 69 is 115% of 60, which means that the error is of:

115 - 100 = 15%

Hope this helps, have a great day! :D

Answer: x= -32

Step-by-step explanation:

6+x/2=1/4(x-4)-1

6 +x/2 = 1/4x -1 -1         distribute

6+ x/2 = 1/4x -2            combine like terms

(6+x/2) = (1/4x -2)        Find GCF for denominator

4(6+x/2) = 4(1/4x -2)      GCF is 4 so multiply by 4 on both sides

24 +x = x-8                 add 8 on both sides

32+x=x                        subtract x

32=-x                           divide by -1 on both sides

-32= x

1 is the greatest common factor of 8 and 15 .

GCF stand for greatest common factor.It is a set of numbers is the largest factor that each and all the number share. GCF is also often used to find the common denominator.

First we need to write common factor of each number.

The common factors of 8 = ( 1,2,4,8)

The common factor of  15= (1,3,5,15)

1 is the  only one common factor here which is divides both 8 and 15.

So 1 is the only and GCF of 8 and 15.

Thus, 1 is the right answer.

The probability of spinning an even number and flipping heads is 1/5

The sections on the spinner are given as

Sample space (sections) = {1, 2, 3, 4, 5}

These sections mean that

P(Even number) = Count of even numbers/Number of sections

So, we have the following representation

P(Even number) = 2/5

Also, we have

Coin = {H, T}

This means that

P(Head) = 1/2

So, we have the probability equation

P(Even and Head) = P(Even) * P(Head)

This gives

P(Even and Head) = 2/5 * 1/2

Evaluate

P(Even and Head) = 1/5

So, the probability is 1/5

Option B, The center 95% of players had an average weight of 151 pounds.

Football players' weights have a mean of 200 pounds as well as a standard deviation of 25 pounds, which corresponds to a normal distribution.

So, let x represent a football player's weight.

X ≅ N(200, (25)²)

The minimal weight of the center 95% of the members is

P(X > 95) = P((95 - 200) ÷ 25) < (X - µ) ÷ σ)

P(X > 95) = P(-4.2 < z)

P(X > 95) = - P(z < -4.2)

P(X > 95) = 0.1512

The needed percentage is 0.1512 × 100 = 151.2 percent.

Answer:

perpendicular

Step-by-step explanation:

Find the slope for both lines and compare. Same slope would mean parallel. Different slopes means intersecting lines. But specifically if the slopes are opposite sign and reciprocals (one is flipped over from the other) then they are perpendicular.

Put them in slope-intercept form to find the slope.

y = mx + b

m is the slope (number by the x)

y = 3(x+7)

distribute the 3.

y = 3x + 21

This line has a slope of 3.

y + 5 = -1/3 x

y = -1/3 x - 5

This line has a slope of -1/3.

-1/3 and 3 are negative reciprocals. They have opposite signs. Also 1/3 is just 3 but flipped over. They are perpendicular.

what is number system ?

A numeral system, also known as a mathematical notation, is a way of writing numbers that uses digits or other symbols to represent the numbers in a given set in a standardised way. In different numeral systems, the same set of symbols may represent various numbers.

Solution:

we want the integers b such that

2013 = 3 ( modb)

=> b is a factor of 2010

since 2010 has 2 * 3 * 5* 67 it has

(1+1)(1+1)(1+1)(1+1) = 16 factors

since b cannot equal to 1, 2, or 3, as these cannot have 3 in there base representation, our answer is 16 - 3 =13.

are all the real numbers.

Here we have a really trivial inequality, which is:

|-2c - 3| > -4

Notice that we have an absolute value there, and the absolute value is defined as:

|x| = x   if x ≥ 0

|x| = -x if   x < 0

Then the absolute value |x| is always equal to or larger than zero, so:

|x| > -4

Is true for any value of x.

Answer:

180-20=60

Answer:

120°

Step-by-step explanation:

Your question didn't include an image or angle names, so it was pretty confusing to get what you were asking for. If you were asking for the exterior angle of the missing angle, then here's your answer:

The 3 angle measures of a triangle will always equal 180.

Since we've already got two angles, all we need to do is a simple equation to get our missing angle:

180-(50+70)=60

Now that we've got the missing angle, we need to calculate the exterior angle, the thing we're here for. We know (hopefully at this point) that an exterior angle and its interior angle are a linear pair, meaning that the two add up to 180. Knowing this, we can do this equation to finish off the question:

180-60=120

And there's your answer, 120°

An equation that can be used to determine the tree's height is 22.5/8.25 = x/5.5.

The height of this tree is equal to 15 feet.

The distance of this person from the tree is equal to 14.25 feet.

In Geometry, two (2) triangles are similar when the ratio of their corresponding sides are equal in magnitude and their corresponding angles are congruent.

Additionally, two (2) geometric figures are considered to be congruent only when their corresponding side lengths are congruent and the magnitude of their angles are congruent.

Now, we can write an equation that can be used to determine the tree's height. Since the ratio of the corresponding sides of similar triangles are equal in magnitude, we have the following mathematical expression (equation):

22.5/8.25 = x/5.5

Where:

x represents the height of the tree.

22.5/8.25 = x/5.5

Cross-multiplying, we have:

8.25x = 22.5 × 5.5

8.25x = 123.75

x = 123.75/8.25

x = 15 feet.

The distance of this person from the tree can be calculated as follows;

Distance = Length of tree's shadow - Length of person's shadow

Distance = 22.5 - 8.25
