Answer:

The cockroach is faster

Step-by-step explanation:

The strategy which would eliminate a variable in the system of equations is to multiply the top equation by 3 ,multiply the bottom equation by -2 then add the equation and is denoted as option B.

This is a mathematical term which is made up of two expressions and is connected by an equal sign.

In the example given below:

2x + 8y = -3

3x + 6y = -4

We can multiply the top by 3 and the bottom by -2 which will result in:

6x + 24y = -9

-6x - 12y = 8

They are then added to each other to give:

6x - 6x + 24y - 12y = -9+8

12y = -1

y = -1/12

From this we can notice that the variable x was eliminated which is why option B is the correct choice.

The rational numbers are -√25, -√25, √100, √0.36, √0.0144 and -√36/49. Select them

A rational number is a number that can be expressed as a fraction where both the numerator and the denominator in the fraction are integers e.g 2/3, 7/1, √100 = 10/1, etc.

An irrational number is any real number that cannot be expressed as the quotient of two integers. This is the opposite of rational numbers. They are usually of roots that cannot give integers e.g 3√5, √8, etc.

√75 = √(25 x 3) = √25 x √3 = 5 x √3 = 5√3    (This is not rational)

-√25 = -5 = -5/1   (This is rational)

2*√7 = 2√7        (This is not rational)

√100 = 10 = 10/1  (This is rational)

√0.36 = √(36/100) = 6/10   (This is rational)

√0.0144 = √(144/10000) = 12/100  (This is rational)

√3/7 = √3/7  (This is not rational)

-√36/49 = -6/7  (This is rational)

Answer:

[tex]\frac{6}{5}[/tex]

Step-by-step explanation:

[tex]\frac{2}{3} *\frac{9}{5} =\frac{18}{15} =\frac{6}{5}[/tex]

The value of the product of 2/3 × 9/5 is 6/5.

In the given question, we have to attempt fraction multiplication.

For fraction multiplication, we simply multiply the respective numerators and denominators with each other.

Here, in 2/3 × 9/5 ⇒ 18/15 (since 2×9=18) (since 3×5=15)

Now, since we can see that both the numerator and denominator in the solution can get divided by 3, we can simplify the fraction by dividing both the numerator and denominator by 3.

On dividing by 3, we get ⇒ 6/5

So, on multiplying 2/3 and 9/5, we get 18/15 which we later simplify into 6/5.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Vivian has 18 signatures, and Kyle has 14.

Vivian is collecting signatures at an average rate of 1 per day, whereas Kyle is averaging 3 signatures every day.

Now,

Since, Vivian has 18 signatures, and Kyle has 14.

And, Vivian is collecting signatures at an average rate of 1 per day, whereas Kyle is averaging 3 signatures every day.

Let number of days it take the same number of signature = x

So, We can formulate;

⇒ 18 + x = 14 + 3x

Solve for x as;

⇒ 18 + x = 14 + 3x

⇒ 18 - 14 = 3x - x

⇒ 4 = 2x

⇒ 2x = 4

⇒ x = 2

Thus, The number of days it take the same number of signature will be 2 days.

Let the sides of the old rectangle are l and w.

Answer: Hence the answer is 27 square feet.

Please look at the images for more details.

The cost of covering the field with grass pallets is $40996.58.

Given that the rectangular field measures 90 m and 162 m.

Hence, the area of the field is 90 X 162 m²

The grass pallets are sure in shape with an area covering 90 square yards.

1 m = 1.09 yards

Hence,

1 m² = 1.09² square yards

Hence,

90 X 162 m² = 90 X 162 X 1.09² square yards

Hence the number of pallets to be used is

(90 X 162 X 1.09²) / 90

= 162 X 1.09² pallets.

= 192.4722 pallets.

1 pallet costs $213

Hence,

192.4722 pallets cost

192.4722 X 213

= $40996.58

Therefore we get the cost of covering the field with grass is  $40996.58.

Events A and B are non-overlapping. Option(2) is correct.

The sets of photographs that don't overlap are the sets where no two pictures (correctly) don't overlap. They are the expansion of the cross-bifix-free sets of strings to two dimensions is called non-overlapping.

A red die and a blue die are rolled.

Assume that Event A is receiving the number 9.

Event B: You receive a double.

Whether events A and B overlap or not is what we want to determine.

When two red dice and two blue dice are thrown, a sample space is then provided by,

S = {(1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (2,1), (2,2), (2,3), (2,4), (2,5), (2,6), (3,1), (3,2), (3,3), (3,4), (3,5),(3,6), (4,1), (4,2), (4,3), (4,4),(4,5),(4,6) (5,1), (5,2), (5,3), (5,4),(5,5),(5,6),(6,1), (6,2),(6,3)(6,4),(6,5),(6,6)}

The two dice are rolled, and there are a total of 36 outcomes.

n(S)=36

Assume that Event A is receiving the number 9.

The probable results for A = (3,6), (4,5), (5,5), (5,6), (6,3)

And let's say that you receive a double in Event B.

The events that may occur if B=(1,1),(2,2),(3,3),(4,4),(5,5),(6,6)

The page is in landscape mode with a width : height is 3: 2

Given that,

The printable area is should be 42 square inches on a rectangular page. The margins at the top and bottom of the page are each one inch, while the margins on one side are one inch and two inches, respectively.

x = length of the horizontal side of the printable area

y = length of the vertical side of the printable area

XY = 42 inch²

y = 42/x

page height = y + 1 + 1

page width = x + 1 + 2

A = area of an entire sheet of paper

  = (x+3)(y+2)

  = (x+3)(42/x+2)

  = x(42/x+2)+3(42/x+2)

  = 42+2x+126/x+6

A = 2x+126/x+48

Extremes occur when A' = 0:

A' = 0 = 2 – 126/x²

1 = 63/x²

x² = 9*7

x = 3√(7), x has to be positive

y = 42/x = 42/(3√(7)) = 14√(7)/7 = 2√(7)

What should the dimensions of the page be so that the least amount of paper is used?

page width = x + 3 = 3√(7) + 3 = 3(√(7) + 1)

page height = y + 2 = 2√(7) + 2 = 2(√(7) + 1)

So, the page is in landscape mode with width: height is 3: 2.

The effect of eliminating the lowest value, 0, from the data set have on the mean and median of the data set is;

The mean of a given data is the sum of all observations divided by the number of observations

The median of a given set of data refers to the middlemost observation, obtained after arranging the data in ascending or descending order.

Given data:

0, 40, 60, 70, 75, 80, 85, 95, 95, 100

a) Mean without '0' = (40+ 60+ 70+ 75+ 80+ 85+ 95+ 95+ 100) / 9

= 700/9

= 77.777

Median without '0' = 40, 60, 70, 75, 80, 85, 95, 95, 100

= 80

Mean with ' 0' = 0+ 40+ 60+ 70+ 75+ 80+ 85+ 95+ 95+ 100 / 10 = 70

Median with '0' = 0, 40, 60, 70, 75, 80, 85, 95, 95, 100

= (75 + 80) / 2

= 77.5

So therefore,

Difference in mean = Median without '0' - Mean with ' 0'

= 77.77 - 70

Difference in median = Median without '0' - Median with '0'

The solution for x in the expression given as 15 + ax/5 =  10 is x = -25/a

From the question, the algebraic expression is given as

15 + ax/5 =  10

There is a constant to add to or subtract from the expression

So, the we subtract 15 from both sides

- 15 + 15 + ax/5 =  10 - 15

Evaluate

ax/5 = -5

Multiply both sides of the equation by 5

This gives

5 * ax/5 = -5 * 5

Evaluate the products

So, we have the following equation

ax = -25

Multiply both sides of the equation by 1/a

This gives

1/a * ax = -25 * 1/a

Evaluate the products in the above expression
