Answer:

Step-by-step explanation:

28 cows × 6 days = 168 cow-days

(168 cow-days)/(21 cows) = 8 days

If a field of grass feeds 28 cows for 6 days, the number of days that the same field would feed 21 cows is 8 days.

This question involves the use of inverse proportion to solve.

According to this question, a field of grass feeds 28 cows for 6 days. The number of days it would take 21 cows is calculated as follows:

28 cows is fed for 6 days

21 cows will be fed for (28 × 6) ÷ 21 = 8 days.

Therefore, If a field of grass feeds 28 cows for 6 days, the number of days that the same field would feed 21 cows is 8 days.

Step-by-step explanation:

The given expression is :

[tex]8.29 \times \frac{ - 5.62 + 5.62}{5.62}[/tex]

We can solve the expression as follows :

[tex]\frac{ - 5.62 + 5.62}{5.62}=\dfrac{0}{5.62}[/tex] (As -5.62+5.62 equals to 0)

Any number multipled to 0 gives 0.

Hence, the value of the given expression is equal to 0.

Step-by-step explanation:

The number of hours he spent babysitting is 12 hours and the number of hours he spent mowing lawns last week is 8 hours.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Given that, John works two jobs. He earns $10 an hour babysitting his neighbour's children and $15 an hour mowing lawns in his neighbourhood. Last week he worked a total of 20 hours and earned a total of $240.

Let the x be the number of hours he spent babysitting and y be the number of hours he spent mowing lawns last week,

Establishing the equation, we get,

x+y = 20

x = 20-y......(i)

10x+15y = 240.......(ii)

Using the equation (i) in (ii), we get

10(20-y)+15y = 240

200-10y+15y = 240

5y = 40

y = 8

Put y = 8 in eq(i)

x = 20-8

x = 12

Hence, the number of hours he spent babysitting is 12 hours and the number of hours he spent mowing lawns last week is 8 hours.

Answer:

Step-by-step explanation:

In parallelogram, diagonals bisect each other

DP = IP

7x - 8 = 3x

7x       = 3x + 8

7x - 3x = 8

      4x = 8

       x = 8/4

     x = 2

NP = YP

3y = 7x - 2

3y = 7*2 - 2

3y = 14 - 2

3y = 12

y = 12/3

y = 4

Isosceles triangle has two equal sides and two congruent bases.

Step-by-step explanation:

Isosceles triangle has three sides out of which two are equal. It has two congruent sides. The angle opposite to base is vertex. The two sides of the triangle are congruent and the angles opposite to these sides are also congruent. It is a special type of triangle which is also called equilateral triangle.

For the given triangle the statement that is true for length x is -

x < 9

What are triangles?

Triangles are a particular sort of polygon in geometry that have three sides and three vertices. Three straight sides make up the two-dimensional figure shown here. An example of a 3-sided polygon is a triangle. The total of a triangle's three angles equals 180 degrees. One plane completely encloses the triangle.

The length of 1 side is = 5 units

The length of second side is = 4 units

A key geometrical concept that connects the lengths of a triangle's sides is the triangle inequality theorem.

It stipulates that the length of the remaining side must be greater than the sum of the lengths of any two sides of a triangle.

The triangle inequality theorem can be written out as follows if a, b, and c are the lengths of a triangle's sides:

b + c > a

a + c > b

b + a > c

Since the sum for the given triangle is 5 + 4 = 9

So, the third side must be less than 9.

Therefore, the inequality is x < 9.

Answer:

y = [tex]\frac{b}{1-m}[/tex]

Step-by-step explanation:

In order to get y by itself, we need to pull y out of 1 and m on the right side.

b = y(1 - m) since y(1 - m) is the same as y - my.

Once we have pulled y out of 1 and m, we can divide both sides by 1 - m

[tex]\frac{b}{1 - m}[/tex] = [tex]\frac{y(1 - m)}{1 - m}[/tex]

We can cancel out the 1 - m on the right side since (1 - m) / (1 - m) = 1

Finally we get our answer:

[tex]\frac{b}{1-m}[/tex] = y

This is the same as y = [tex]\frac{b}{1-m}[/tex]

P(E) = 0.5

P(A) = 0.2

P(N) = 0.3

Conditional probability ;

0.47

Step-by-step explanation:

Let :

E = Excellent ; A = Average ; N = not up to standard

P(E) = 0.5

P(A) = 0.2

P(N) = 0.3

If Leo shows up ; this type of probability is called a conditional probability. It is the likelihood of an event based on a certain or already satisfied condition.

The probability that Leo is coming :

Leo ; Excellent = 0.7

Leo ; Average = 0.3

Leo; Not up to standard = 0.2

Hence, probability they Leo is coming :

(0.5 * 0.7) + (0.2 * 0.3) + (0.3 * 0.2)

0.35 + 0.06 + 0.06

= 0.47

Answer:

177

Step-by-step explanation:

If the top 5 performers are not considered, the average drops by 2.

Thus,average without top 5 performers = 85 - 2 = 83

Total scored with 5 table toppers = 52 × 85 = 4420

Total scored without 5 table toppers = 47 × 83 = 3901

Total scores of top 5 table toppers = 4420 - 3901 = 519

We are told that each of the 5 top scorers had distinct integral scores.

Also, all of them will score greater than 83.

Thus,possible maximum score of table topper = 519 - (84 + 85 + 86 + 87) = 177

Step-by-step explanation:

Odds to probability:

Odds of a:b

The probability is given by:

[tex]p = \frac{a}{a+b}[/tex]

Anne Hathaway 2:11

So [tex]p = \frac{2}{2+11} = \frac{2}{13} = 0.154[/tex]

Angelina Jolie 1:20

So [tex]p = \frac{1}{1+20} = \frac{1}{21} = 0.048[/tex]

Melissa Leo 1:33

So [tex]p = \frac{1}{1+33} = \frac{1}{34} = 0.029[/tex]

Meryl Streep 3:10

So [tex]p = \frac{3}{3+10} = \frac{3}{13} = 0.231[/tex]

Kate Winslet 5:2

So [tex]p = \frac{5}{5+2} = \frac{5}{7} = 0.714[/tex]
