The perimeter of a rectangle is the sum of all four sides of the rectangle.

(Perimeter = 2width + 2length)

Let's assume the width of the rectangle to be x.

For length, the statement says that is equals to 3 times the width (= 3x) and 5cm more meaning 5cm would be added to 3 times the width.

Width = x

Length = 3x + 5

Perimeter = 2x + 2(3x+5)

74 = 2x + (6x+10)

74 = 8x + 10

solve for x

8x = 74 - 10

x = 64/8, x=8

Width = 8

length = 3(8)+5 = 29

(5,1)

x=5

y=1

m=1/2

Use this formula

y-y1=m(x-x1)

y-1=1/2(x-5)

y-1=x/2-5/2

Isolate for y

y=x/2-3/2

Hope this helps.

Answer:x-2y=3

Step-by-step explanation:

Given

Lines passes  through (5,1) and slope of 0.5

i.e. [tex] tan\theta =0.5[/tex]

where [tex]\theta [/tex]is the angle made by line with horizontal

equation of line can be given by

[tex]\frac{y-1}{x-5}=tan\theta [/tex]

2y-2=x-5

x-2y=3 is the required line

Divide total miles driven by the total amount of gas used to find the number of miles per gallon.

Then multiply that by the number of gallons you want to find out:

268 miles / 12 gallons = 22.333 miles per gallon.

22.333 miles per gallon x 9 gallons = 201 total miles.

Answer:

7/8

Step-by-step explanation:

The strip is 21 7/8 inches long. You need to make this into an improper fraction so you multiply 21x8= 168 and then add 7 to that which = 175. So the improper fraction is 175/8 (instead of 21 7/8). Now you just divide 175 by 25 which is 7. Each stamp is 7/8 inches long.

To find the new length of the strip after Vanessa uses one stamp, we first divide the initial length of the strip by the total number of stamps to find the length of one stamp. We then subtract this from the original length of the strip. The new length is 21 inches.

This question is asking how long a strip of stamps is after Vanessa uses one of them. Given that the original strip is 21 7/8 inches long and includes 25 stamps, we can find the length of one stamp by dividing the total length of the strip by the total number of stamps. So, the length of one stamp is 21 7/8 ÷ 25.

We then subtract the length of this one stamp from the original length of the strip to find the new length:

The new length of the strip, after Vanessa uses one stamp, is therefore 21 inches.

The result of the division of x³-7 by x+2 will be (x²−2x+4)−15/(x+2).

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Division = divide any two numbers or variables called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

Division of (x³-7) ÷ (x+2)

Keep quotient x² → (x³-7) - (x³+2x²) ⇒ remainder = -7-2x²

Next quotient -2x → (x³-7) - (-2x²-4x) ⇒ remainder = -7+4x

Next quotient 4 →  (x³-7) - (8+4x) ⇒ reminder = -15

Therefore,

(x³-7) ÷ (x+2) = (x²−2x+4)−15/(x+2).

Hence "The result of the division of x³-7 by x+2 will be (x²−2x+4)−15/(x+2)".

To solve the multiplication problem and simplify the fractions, follow these steps:

Multiply 32/5 × 513/1:

(32/5) × (513/1) = (32 × 513) / (5 × 1) = 16416 / 5

Now, let's find how many novels Jeffrey owns. He owns 230 books, and of them are novels:

Number of novels = (Number of novels) / Total books

Number of novels = (3/9) × 230

Number of novels = (1/3) × 230

Number of novels = 230 / 3

Number of novels = 76⅔ (mixed number)

To simplify the mixed number 76⅔, remember that ⅔ is equivalent to 2/3.

76⅔ = 76 + ⅔ = 76 + 2/3 = (76 × 3 + 2) / 3 = 230 / 3

So, Jeffrey owns 76⅔ novels.

For the standardized test practice, we have two fractions:

Isolate the z. Note the equal sign. Subtract 1/7z to both sides

1/7z (-1/7z) + 2 = -6/7z (-1/7z)

2 = -6/7z - 1/7z

The simplification involves the use of the difference of squares identity on the first two terms, yielding (x - y). There's no further simplification possible for the remaining terms (x + y)(x^2 + y^2) under general conditions, resulting in the expression (x - y)(x + y)(x^2 + y^2).

The question involves the simplification of the given expression (
oot{x} + oot{y})(oot{x} - oot{y})(x + y)(x^2 + y^2). To simplify it, we will use the properties of square roots and algebraic identities.

Firstly, we use the difference of squares identity on the first two terms: (
oot{x} + oot{y})(oot{x} - oot{y}) = x - y.

Now, we look at the second pair of terms and realize that we can reshape the given expression using the properties of exponents: (x + y)(x^2 + y^2). Since both (x + y) and (x^2 + y^2) represent sums of powers of x and y, there is no direct simplification possible without additional constraints on x and y.

Therefore, the multiplication of these expressions gives us (x - y)(x + y)(x^2 + y^2) without further simplification under general conditions.

The density of the object is [tex]0.1067[/tex] grams per cubic centimeter. (Rounded off to 4th decimal)

Step-by-step explanation:

Density = [Mass/Volume]

Here we have been given the dimensions of the object.

Volume = Height * Width * Length

Volume = [tex]3.0cm*15.0cm*5.0cm[/tex]

             =[tex]225cm^{3}[/tex]

Now we can substitute the Mass and the Volume to the density equation.

Density = [Mass/Volume]

             =[tex]\frac{24grams}{225cm^{3} }[/tex]

             =[tex]0.1067[/tex] grams per cubic centimeter. (Rounded off to 4th decimal)

The area of the stretched triangle is four times the area of the original triangle

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let's assume that the original triangle has sides of length a, b, and c, and that its area is A. Without loss of generality, we can assume that side a is the shortest side.

After the rubber is stretched, each side of the enlarged triangle will be twice the length of its original length. Thus, the lengths of the sides of the stretched triangle will be 2a, 2b, and 2c.

Since the rubber is stretched equally from all sides, we know that each angle of the original triangle will be doubled. Therefore, the stretched triangle will be similar to the original triangle.

The area of a triangle is given by the formula:

A = (1/2) x base x height

where the base and height are the lengths of any two sides of the triangle that are perpendicular to each other.

Since the stretched triangle is similar to the original triangle, we can use the ratios of corresponding sides to find the lengths of the corresponding altitudes. Specifically, we have:

(altitude of stretched triangle corresponding to side 2a) = 2 x (altitude of original triangle corresponding to side a)

(altitude of stretched triangle corresponding to side 2b) = 2 x (altitude of original triangle corresponding to side b)

(altitude of stretched triangle corresponding to side 2c) = 2 x (altitude of original triangle corresponding to side c)

Therefore, the area of the stretched triangle is given by:

A' = (1/2) x (2a) x (2b) x (2/2) + (1/2) x (2b) x (2c) x (2/2) + (1/2) x (2c) x (2a) x (2/2)

Simplifying this expression gives:

A' = 4A

Hence , the area of the stretched triangle is four times the area of the original triangle.

Final answer:

Exponents are used for repeated multiplication of the same number, hence, (3 inches)(5 inches) and (5 feet)(2 feet) cannot be simplified using exponents since they involve different numbers. Exponents and conversion factors are distinct mathematical tools, with the latter used for converting units of measure.

Explanation:

The question addresses using exponents to express products of the same units in a simpler form. The product of (3 inches)(5 inches) suggests multiplying these two measurements, however, when writing this product using exponents, we should consider that both are units of length, and thus their product will result in a unit of area, which is square inches (in2). We cannot simplify this expression further using exponents as they are not repeated multiplication of the same number.

On the other hand, for the product (5 feet)(2 feet), we again get an area, but this time in square feet (ft2). Still, there's no need for using exponents in this expression because we are not dealing with repeated multiplication of the same number.

It is important to note that exponents are used to represent repeated multiplication of the same number. For example, if we had (5 inches)(5 inches), we could write this as 5 inches squared (5 in)2, because it's 5 inches multiplied by itself. On the contrary, when multiplying different numbers, exponents don't apply.

When converting between different units of measure, as in converting feet to inches, we use conversion factors. For instance, 1 foot equals 12 inches, so by multiplying feet by 12, we can convert it to inches. Similarly, inches can be converted to feet by dividing by 12.
