Answer:

Part 1: Less.

Part 2: Greater.

Part 3: Greater.

Part 4: Less.

Part 5: Equal.

Step-by-step explanation:

Part 1: Assume that the value is x initially.

So, 55% decrease of value of x will give [tex]x(1 - \frac{55}{100}) = 0.45x[/tex].

Again, 25% increase of the value obtained will give [tex]0.45x(1 + \frac{25}{100}) = 0.45 \times 1.25 \times x = 0.5625x[/tex]

So, it is less than x. (Answer)

Part 2: Assume that the value is x initially.

So, 75% increase followed by [tex]33\dfrac{1}{3}  = 33.33[/tex]% decrease will give [tex]x \times (1 + 0.75) \times (1 - 0.333) = x \times 1.75 \times 0.667 = 1.167x[/tex]

So, it is greater than x.

Part 3: Assume that the value is x initially.

So, 20% decrease followed by 40% increase will give [tex]x \times (1 - 0.2) \times (1 + 0.4) = x \times 0.8 \times 1.4 = 1.12x[/tex]

So, it is greater than x.

Part 4: Assume that the value is x initially.

So, 30% increase followed by 30% decrease will give [tex]x \times (1 + 0.3) \times (1 - 0.3) = x \times 1.3 \times 0.7 = 0.91x[/tex]

Hence, it is less than x.

Part 5: Assume that the value is x initially.

So, 100% increase followed by 50% decrease will give [tex]x\times (1 + 1) \times (1 - 0.5) =x \times 2 \times 0.5 = x[/tex]

Hence, the final value is same as x. (Answer)

Answer:

[tex]slope =\frac{5}{4}[/tex]

Step-by-step explanation:

A(0,-1)  B(5,3) is missing in the question

The points for A  and B are missing. A(0,-1)  B(5,3)

To find the slope of line AB using the formula

[tex]slope =\frac{y_2-y_1}{x_2-x_1}[/tex]

A(0,-1) is (x1,y1)

B(5,3) is (x2,y2). plug in the values in the formula

[tex]slope =\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]slope =\frac{5-0}{3+1}[/tex]

[tex]slope =\frac{5}{4}[/tex]

To calculate the slope of line CD, you need two points on the line. The slope is the 'rise over run' between these points, calculated with the formula (y2 - y1) / (x2 - x1), but coordinates for line CD were not provided.

To determine the slope of line CD, you need two points on line CD. The slope is found by calculating the rise over run between two points on the line. According to the information provided, we can use the general process for calculating slope which entails subtracting the y-coordinate of the starting point from the y-coordinate of the ending point (change in y), and dividing that by the subtraction of the x-coordinate of the starting point from the x-coordinate of the ending point (change in x). If we had the actual coordinates for line CD, the formula would look like this:

slope = (y2 - y1) / (x2 - x1)

However, specific coordinates for line CD are not provided in the question. To accurately calculate the slope, you would need to refer to the graph or data given for line CD and choose two distinct points to use in the slope formula.

Answer:

Essentially, the slope that is parallel to the pair is the the slope of the pair of points.

Using the formula [tex]\frac{y_1-y_2}{x_1-x_2}[/tex], the answer is [tex]\frac{-2}{-12}=\frac{1}{6}[/tex]

Answer: shown below

Step-by-step explanation:

It’s hard to explain but,

First you need to find the slope and y intercept of the equation and graph that. Graph y=3x-5. Graph y= -2x+3. Graph y=2. (In case you don’t know, f(x) is y.)

Then use the equation after the “if”. For example, to graph -1 < x < 4 for the equation y= -2x+3, find the numbers -1 and 4 located on the graph and find the points y=-2x+3 has on number -1 and 4. Both numbers are a open circle.

Do the same for the rest of the equations.

For the equation y= 2, the equation is x>4 (there’s a line under >, just can’t add it), Locate 4 on the graph. Find the point above 4. It is a closed circle pointing to the right because it is all numbers greater than or equal to 4.

Then for the equation y= 3x-5, the equation for it is x< -1. (Again, there’s a line under <) Find -1 on the graph. Look for the point y=3x-5 has under -1. It is a closed circle because all numbers are less than or equal to -1.

Answer:

C = 6500 + 225n

Step-by-step explanation:

It will cost $6500 to rent a truck plus $225 for each ton of sugar transported.

So, in the equation which relates the total cost for transporting sugar in a truck, $6500 will be the initial value and $225 will be the rate of transporting sugar per ton.

Hence, for transporting n tons of sugar, the total cost C in dollars is given by the following equation  

C = 6500 + 225n (Answer)

The dimensions of the box are 10 ft and 5 ft

The maximum volume is 500 ft³

Step-by-step explanation:

A rectangle box with

Surface area of a box without top (SA) = perimeter of base × height + area of the base

Volume of a box (V) = base area × height

Assume that the length of the side of the square base is x and the height of the box is y

∵ It needs to be made using 300 ft² of material

∴ The surface area of the box is 300 ft²

∵ Its base is a square of side length x ft

∴ Perimeter of the base = 4 × x = 4 x

∴ Area of the base = x²

∵ The height of the box = y ft

∵ SA = perimeter of base × height + area of the base

∵ SA = (4x)(y) + x²

∴ SA = 4xy + x²

∵ SA of the box = 300 ft²

- Equate the two expressions of SA

∴ 4xy + x² = 300

Now let us find y in terms of x

- Subtract x² from both sides

∴ 4xy = 300 - x²

- Divide each term by 4x to find y

∴ [tex]y=\frac{75}{x}-\frac{1}{4}x[/tex]

∵ V = area of the base × height

∴ V = x² × y = x²y

- Substitute y by the equation of it above

∴ [tex]V=x^{2}(\frac{75}{x}-\frac{1}{4}x)[/tex]

∴ [tex]V=75x-\frac{1}{4}x^{3}[/tex]

∵ The volume of the box is greatest

- That means differentiate V and equate it by 0

∵ [tex]\frac{dV}{dx}=75-\frac{3}{4}x^{2}[/tex]

∵ [tex]\frac{dV}{dx}=0[/tex] ⇒ greatest volume

∴ [tex]75-\frac{3}{4}x^{2}=0[/tex]

- Subtract 75 from both sides

∴ [tex]-\frac{3}{4}x^{2}=-75[/tex]

- Divide both sides by [tex]-\frac{3}{4}[/tex]

∴ x² = 100

- Take √ for both sides

∴ x = 10

Substitute the value of x in the equation of y

∵ [tex]y=\frac{75}{10}-\frac{1}{4}(10)[/tex]

∴ y = 5

The dimensions of the box are 10 ft and 5 ft

∵ [tex]V=75x-\frac{1}{4}x^{3}[/tex]

∵ x = 10

∴ [tex]V=75(10)-\frac{1}{4}(10)^{3}[/tex]

∴ [tex]V=750-\frac{1}{4}(1000)[/tex]

∴ V = 750 - 250

∴ V = 500 ft³

The maximum volume is 500 ft³

Answer:

5.898

Step-by-step explanation:

There are 365 days in a year.

There are 24 hours in a day.

There are 60 minutes in an hour.

In a day, there are 60 minutes each hour x 24 hours = 1440 minutes

In a year, there are 1440 minutes per day x 365 days = 525600 minutes

3.1 million = 3,100,000

3,100,000 / 525600 = 5.898 (rounded from 5.89802130898)

To calculate deaths per minute from an annual total of 3.1 million, we divide the total by days in a year, then by hours in a day, and finally by minutes in an hour, resulting in approximately 6 deaths per minute.

To find out how many deaths occur per minute from an annual total of approximately 3.1 million, we use a step-by-step mathematical calculation.

We start by dividing the total annual deaths by the number of days in a year, and then further dividing by the number of hours in a day, and finally by the number of minutes in an hour.

Therefore, on average, there are approximately 6 deaths per minute worldwide given an annual total of 3.1 million deaths.

Answer:

1)121.5 sq.yards

2)157.92 m²

3)5.434 ft²

4)147.4513 cm²

5)147 cm²

6)56 in²

Step-by-step explanation:

1) Area of shaded region= Area of rectangle-Area of triangle

Area of rectangle= Length*Breadth=18*9 sq.yards=162 sq.yards(length=18 yards and breadth=9 yards)

Area of triangle= [tex]\frac{1}{2}*Base*Height[/tex]=[tex]\frac{1}{2}*9*9[/tex]=40.5 sq.yards(base=9 yards and height= 9 yards)

Therefore,Area of shaded region=162-40.5=121.5 sq.yards

2) In the following figure,

Length of rectangle, l= 21 m

breadth of rectangle, b= 15 m

Radius of circles, r= 5 m

Area of rectangle=l*b=21*15=315 m²

Area of circle= π[tex]r^{2}[/tex]=π*[tex]5^{2}[/tex]=78.54 m²

Therefore,Area of shaded region= Area of rectangle-2*Area of circle

                                                       =315-2*78.54=157.92 m²

3) In the following figure,

Radius of circle, r= 2 ft

Base of triangle, b= 6 ft

Height of triangle, h=6 ft

Area of circle= π[tex]r^{2}[/tex]=π*[tex]2^{2}[/tex]=12.566 ft²

Area of triangle= [tex]\frac{1}{2}*Base*Height[/tex]

                         =[tex]\frac{1}{2}*6*6[/tex]=18 ft²

Therefore,Area of shaded region= Area of triangle- Area of circle

                                                       = 18-12.566=5.434 ft²

4) In the following figure,

Radius of circle, r= 6 cm

Length of rectangle, l= 17 cm

breadth of rectangle, b= 2*r= 12 cm

Area of semi-circle= π[tex]\frac{r^{2}}{2}[/tex]=π*[tex]\frac{6^{2}}{2}[/tex]

                               =56.5487 cm²

Area of rectangle=l*b=17*12=204 cm²

Therefore,Area of shaded region= Area of rectangle- Area of semi-circle

                                                       = 204-56.5487=147.4513 cm²

5) In the following figure,

Side of bigger square, a=14 cm

Side of smaller square, b=7 cm

Area of bigger square= [tex]a^{2}[/tex]=[tex]14^{2}[/tex]=196 cm²

Area of smaller square= [tex]b^{2}[/tex]=[tex]7^{2}[/tex]=49 cm²

Therefore,Area of shaded region= Area of bigger square- Area of smaller                                                                                              square

                                                       =196-49=147 cm²

6) In the following figure,

Length of rectangle, l= 10 in

breadth of rectangle, b= 8 in

Base of triangle, b= 8 in

Height of triangle, h=6 in

Area of rectangle=l*b=10*8=80 in²

Area of triangle= [tex]\frac{1}{2}*Base*Height[/tex]

                         =[tex]\frac{1}{2}*8*6[/tex]=24 in²

Therefore,Area of shaded region= Area of triangle- Area of circle

                                                       = 80-24=56 in²

Answer:

37 : 46

Step-by-step explanation:

I nickel is equivalent to 0.05 dollars.

So, 37 nickels are equivalent to (0.05 × 37) = 1.85 dollars.

Again, we can write 1 dime is equal to 0.1 dollars.

So, 23 dimes are equivalent to (23 × 0.1) = 2.3 dollars.

Therefore, to compare 37 nickels to 23 dimes as a ratio reduced to lowest term will be 1.85 : 2.3 = 185 : 230 = 37 : 46 (Answer)

Final answer:

To write the comparison of 37 nickels to 23 dimes as a ratio in lowest terms, you convert the value of nickels and dimes to cents and simplify the ratio value-wise, resulting in a simplified ratio of 37:46.

Explanation:

The student is asking to express the comparison of 37 nickels to 23 dimes as a ratio reduced to lowest terms. Since both nickels and dimes are types of coins, it helps to understand that their value does not directly translate to a quantity ratio but rather a value ratio. A nickel is worth 5 cents, and a dime is worth 10 cents. Therefore, the value ratio of nickels to dimes is 5 cents per nickel to 10 cents per dime.

To find the simplified ratio, we can represent the comparison of the value of 37 nickels to 23 dimes as:

This ratio can be reduced by dividing both terms by the greatest common divisor of 185 and 230, which is 5:

So, the simplified ratio is 37:46.

do the multiplication first and then add

When adding numbers in scientific notation, align the exponents and then add the coefficients. The sum of 1.2 x 10^5 and 5.35 x 10^6 is 5.47 x 10^6.

To add these two numbers in scientific notation, we need to first align the exponents. In this case, we can rewrite the first number as 0.12 x 10^6 and the second number as 5.35 x 10^6. Now, we can add the numbers together:

0.12 x 10^6 + 5.35 x 10^6 = 5.47 x 10^6. Thus, the sum of 1.2 x 10^5 and 5.35 x 10^6 is 5.47 x 10^6.

Answer:

A.) -9

Step-by-step explanation:

it is observed that triangles ABL and KML are similar triangles

hence the following ratios are valid:

LA / LK = LB/LM = AB/KM

we can see that LA/LK = LB/LM = 1/2

hence the above ratio becomes

1/2 = AB/KM  (rearranging)

KM = 2AB

We are given that KM = (x + 21) and AB = (x + 15)

hence

KM = 2AB

(x + 21) = 2 (x + 15)

x + 21 = 2x + 30

x - 2x = 30 - 21

-x = 9

Answer:

81 and -31

Step-by-step explanation:

x + (x - 112) = 50

2x - 112 = 50

2x = 162

x = 81

the other number is x-112 = 81 - 112 = -31

Final answer:

To find the two numbers, set up a system of equations based on the given information. Solve the system of equations to find the values of the two numbers, which are -31 and 81.

Explanation:

To find the two numbers, we can set up a system of equations based on the given information.

Let's assume one number is x, and the other number is y.

According to the problem, the sum of the two numbers is 50, so we can write the equation:

x + y = 50

We are also told that one number is 112 less than the other, so we can write another equation:

x = y - 112

Now we can solve this system of equations to find the values of x and y.

Substituting the value of x from the second equation into the first equation, we have:

(y - 112) + y = 50

Combining like terms, we get: 2y - 112 = 50

Adding 112 to both sides of the equation, we have: 2y = 162

Dividing both sides by 2, we get: y = 81

Substituting this value of y into the second equation, we have: x = 81 - 112

Simplifying, we get: x = -31

Therefore, the two numbers are -31 and 81.

Answer:

It is not a right triangle.

Step-by-step explanation:

We can prove this by Pythagorean theorem because it represents to a right triangle.

Pythagorean theorem:

a² + b² = c²

Now substitute the values.

Note: the longest side will represent c

So,

a = 10 m

b = 16 m

c = 20 m

10² + 16² = 20²

The objective here is to make them equal.

100 + 256 = 400

356 ≠ 400

They are not equal so it is not considered a right triangle.

By applying the Pythagorean theorem to the triangle with side lengths of 10 metres,16 metres, and 20 metres, we can verify that it is a right-angled triangle due to the equality 10² + 16² = 20².

In Mathematics, specifically in Geometry, we can determine if a triangle is a right triangle using the Pythagorean theorem. This theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This formula is expressed as a² + b² = c² where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

Applying the Pythagorean theorem to the triangle with side lengths of 10 metres,16 metres, and 20 metres, we set 20 metres (the largest measurement) as c (the hypotenuse) and the other two measurements as a and b. Thus, the equation becomes 10² + 16² = 20². After calculating, we find that 100 + 256 does indeed equal 400. Because these values are equal, the triangle is a right angled triangle.

Answer:

1. Collinear

2. Parallel

3. Oblique

Step-by-step explanation:

1. The system of linear two variable equations are  

3x - 2y = 2 ........... (1) and  

6x - 4y = 4, ⇒ 3x - 2y = 2 ........... (2) {Dividing both sides with 2}

So, equations (1) and (2) are identical.  

Therefore, the lines are collinear. (Answer)

2. The system of linear two variable equations are  

4x - 3y = 12  

⇒ 3y = 4 x - 12

⇒ [tex]y = \frac{4}{3} x - 4[/tex] {In slope-intercept form} ......... (3)

And, - 12x + 9y = 10

⇒ 9y = 12x + 10

⇒ [tex]y = \frac{4}{3} x + \frac{10}{9}[/tex] {In slope-intercept form} .......... (4)

Since, equation (3) and (4) has the same slope, so, they are parallel. (Answer)

3. The system of linear two variable equations are  

3x + 2y = 19

⇒ [tex]y = - \frac{3}{2} x + \frac{19}{2}[/tex] ........... (5)

And, 4x - 5y = 10

⇒ [tex]y = \frac{4}{5}x - 2[/tex] ........ (6)

So, from the equations (5) and (6) we can say that the straight lines are oblique (intersecting). (Answer)
