Answer:

When the force exerted by one team slackens, the force exerted by their third law, each team pulls the opposite team with equal force in a tug of war.  So the two forces don't balance each other and the rope accelerates towards the stronger team.

Answer:

Step-by-step explanation:

It does not need to be an improper fraction.

For example, the numerator and denominator of 10/11 are both greater than 9, but 10/11 is not an improper fraction.

Answer:

Remember that a number divided by itself is 1. That means if the numerator and denominator are the same, the fraction is equal to 1. So all of the following are equal to 1: 2/2, 3/3, 4/4, and so on and so forth. so a good one you could do is 9/9

Step-by-step explanation:

Answer:

2 2/5

Step-by-step explanation:

We need to find out how many gallons of water so,

16/20 = water

3 gallons * 16/20 = 48/20 = 2 8/20 = 2 2/5

this works because then cranberries would be:

2 2/5/16 = 15/100

and for sugar that means

15/100 * 3 = 45/100

so in total

2 40/100 + 45/100 + 15/100 = 3 gallons

and if we simpilfy 2 40/200 we get 2 2/5

Step-by-step explanation:

boy count is 1476

Explanation:

There is an important difference between the way counts are viewed in ratio to that in fractions.

The ratio of boys : girls

→

4

:

5

so you have 4 boys and 5 girls making the whole count

4

+

5

=

9

in its simplest form.

So to change the ratio proportion into fraction proportion we have:

boys

→

4

9

of the whole.

girls

→

5

9

of the whole.

It is given that the whole is 3321 therefore the count of boys is:

4

9

×

3321

=

1476

The younger sister is 10 years old and the elder sister is 15 years old.

Let's represent the present ages of the two sisters as x and y, where x is the age of the elder sister and y is the age of the younger sister.

According to the given information, the product of their present ages is 150:

x * y = 150 ---(1)

It is also stated that 5 years ago, the elder sister was twice as old as her younger sister:

x - 5 = 2 * (y - 5) ---(2)

We can now solve these two equations simultaneously to find the ages of the two sisters.

From equation (2), we can simplify:

x - 5 = 2y - 10

x = 2y - 10 + 5

x = 2y - 5

Substituting this value of x into equation (1), we have:

(2y - 5) * y = 150

2y^2 - 5y = 150

2y^2 - 5y - 150 = 0

Now we can solve this quadratic equation either by factoring, completing the square, or using the quadratic formula. By factoring, we find:

(2y + 15)(y - 10) = 0

This gives us two possible solutions for y:

2y + 15 = 0 --> y = -7.5 (Discard this since age cannot be negative)

y - 10 = 0 --> y = 10

So, the younger sister is 10 years old.

To find the elder sister's age, we can substitute this value of y into equation (2):

x = 2y - 5

x = 2 * 10 - 5

x = 20 - 5

x = 15

Therefore, the elder sister is 15 years old.

for such more question on ages

Answer:

Rhombus

Step-by-step explanation:

Sketching out the shape shows us that it is neither a square nor rectangle (alternatively, we could tell from the points since if it was a rectangle/square, there would be two sets of x co-ordinate values and y-co-ordinate values only).

Find the length of MN:

MN²=(Yn-Ym)²+(Xn=Xm)²

MN²=(4-1)²+(3-1)²

MN²=3²+2²

MN²=9+4

MN=√13

Find the length of MP:

MP²=(Yp-Ym)²+(Xp-Xm)²

MP²=(3-1)²+(4-1)²

MP²=2²+3²

MP²=4+9

MP=√13

Since the side lengths are equal, the shape must be a rhombus.
