What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

What is the quotient?

When two numbers are divided by each other, the result is a quotient. For instance, when we divide 6 by 3, the result is 2, which is the quotient. An integer or a decimal number can be the quotient. We have an integer as the quotient for precise divisions, like 10 5 = 2, and a decimal for erroneous divisions, like 12 5 = 2.4.

As shown in the table, the words- is, gives, and yields will have the equal sign

Another name for subtraction is a difference. Times, product, and multiplication will have the same symbols.

The correct statement about the area and perimeter of Triangle 2 is true are,

⇒ The perimeter is 4.1 times the perimeter of Triangle 1, and the area is 16.81 times the area of Triangle 1.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

Triangle 1 is dilated by a scale factor of 4.1 using the origin as the center of dilation to create Triangle 2.

Now, We get;

The Triangle 1 is dilated by a scale factor of 4.1 using the origin as the center of dilation to create Triangle 2.

Hence, The perimeter of triangle 2 is 4.1 times the perimeter of Triangle 1.

And, We know that;

Area of triangle = 1/2 x Base x Height

So, The area of triangle 2 is 16.81 times the area of Triangle 1.

Answer:

53 weeks (rounded)

Step-by-step explanation:

First, subtract 16.25 from 108 (108 - 16.25), resulting in 91.75

Next, you divide. 91.75/1.75

You would get 52.42... but you would have to add a week to actually get the game.

Answer:

b

Step-by-step explanation:

You have to solve all the equations to find which one equals 8

For a, you can take away the zero which leaves you with 72/9 which is 8. Then you add the zero back to the answer which gives you 80.

For b, you can cancel out the zeroes from 720 and 90 which gives you 72/9 again. That leaves you with 8.

For c, take away the zeroes leaving you with 72/9. Then you have 800 when you add the zeroes back.

For d, you can cancel out one of the zeroes which will give you 720/9. Then you take away the zero and now you have 72/9 again. Then add the zero to the answer which will give you 80.

Because b is the only equation that equals 8, it must be the answer.

Answer:

1=0

4= -16

5=56

6=14

7=12

8=5

Step-by-step explanation:

1 foot = 0.305 m

12 ft = 12 × 0.305 = 3.66m

26 ft = 26 × 0.305 = 7.93m

14ft = 14 × 0.305 = 4.27m

volume = lwh

V = 3.66 × 7.93 × 4.27 = 123.9m³

to the nearest cubic meter = 124m³

The correct equation that represents Y, the gas company’s monthly charge in dollars for using X hundred cubic feet of natural gas is:

Y = 0.6924X + 16

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

The correct equation that represents Y, the gas company’s monthly charge in dollars for using X hundred cubic feet of natural gas is:

Y = 0.6924X + 16

Now,

Option A has the correct variable coefficients, but the constant term is negative, which is not correct as a monthly service fee is always positive.

Option B has the correct constant term but the variable coefficient is positive, which doesn't make sense as the company charges per hundred cubic feet of natural gas used.

Option C has a similar problem as option A.

Option D has incorrect variable and constant terms.

Therefore,

The correct equation is Y = 0.6924X + 16.

let the interior angle of a triangle be 4x,6x and 8x

According to the question,

The interior angles of the triangle=180

4x+6x+8x=180

or, 18x=180

or,x=180÷18

therefore ans x=10

1st angle=4x( putting the value of x)

Given equation:

If n is negative then we get:

If n is negative then x is less than - 5.

Example:

Answer:

x < -5

Step-by-step explanation:

Now the value of x is,

→ 5 + x = n

→ x = n - 5

The value of n when negative,

→ n < 0 ---- {n = 0}

When n is a negative number,

→ x < 0 - 5

→ [ x < -5 ]

Hence, the answer is x < -5.

Answer: The actual distance between the towns is 70 miles

Actual distances

Given that the map scale is 1 inch to 20 miles

If the distance between Milltown and Summerville is 3.5 inches on a map, the actual distance between the towns is expressed as:

Actual distance = 3.5 * 20

Actual distance = 70 miles

Hence the actual distance between the towns is 70 miles
