Answer:

 Perimeter of the polygon p = 24

Step-by-step explanation:

Step(i):-

Given the vertices of a polygon are

P(0,4) ,Q( 5,4) ,R( 5,-3) and S(0,-3)

The distance of PQ

 [tex]a = PQ = \sqrt{(4-4)^{2} +(5-0)^{2} } = \sqrt{25} =5[/tex]

The distance of QR

[tex]b = Q R= \sqrt{(-3-4)^{2} +(5-5)^{2} } = \sqrt{49} =7[/tex]

The distance of RS

[tex]c = RS = \sqrt{(0-5)^{2} +(-3+3)^{2} } = \sqrt{25} =5[/tex]

The distance of PS

[tex]d = PS = \sqrt{(0-0)^{2} +(-3-4)^{2} } = \sqrt{49} =7[/tex]

Step(ii):-

Perimeter of the polygon

       = sum of all sides of polygon

p = a+ b+ c+ d

p = 5+7+5+7

p = 24

Final answer:-

 Perimeter of the polygon p = 24

Answer:

Step-by-step explanation:

r = 1.5 in ,    V = 56.52 in³

V = π × r² × h

56.52 = π × (1.5)² × h

56.52 = π × 2.25 × h

[tex]h=\dfrac{56.25}{2.25\pi}=\dfrac{25}{\pi}\ in=7.9577...\ in\approx8\ in[/tex]

Answer:

B. 2x + 12 = 28

Step-by-step explanation:

x is representative of the wingspan of the vampire bat. suppose the ghost bat has a wingspan of 28 inches.

if the wingspan of a ghost bat is 12 more than twice the vampire bat's, then 2x + 12 is the equation used to find the ghost bat's wingspan. we already know the ghost bat's wingspan is 28, therefore the equation is 2x + 12 = 28

Answer:

'Twice the sum of a number and 5' can be translated into variable expression such as:

Step-by-step explanation:

Given the phrase

Twice the sum of a number and 5

First, let us breakdown the English Phrase

Let the number be = n

The sum of a number 'n' and 5 = n + 5

now, twice the sum of a number and 5 can be determined by multiplying (n+5) with 5.

Thus,

'Twice the sum of a number and 5' can be translated into variable expression such as:

Answer:

x^2+2x-15

Step-by-step explanation:

Answer:

x² + 2x - 15

Step-by-step explanation:

Solve by using FOIL (First, Outside, Inside, Last). This distributes the numbers:

(x + 5)(x - 3)

Use FOIL:

x(x) + x(-3) + 5(x) + (5)(-3)

Simplify:

x(x) + x(-3) + 5(x) + (5)(-3)

x² + x(-3) + 5(x) + (5)(-3)

x² - 3x + 5(x) + (5)(-3)

x² - 3x + 5x + (5)(-3)

x² - 3x + 5x - 15

Combine like terms.

x² + 2x - 15

Your final answer would be x² + 2x - 15

Answer:

x=-2/3 y+ 5/3

Step-by-step explanation:

3x+2y+−2y=5+−2y

3x=−2y+5

3x/3 = -2y+5/3

x = -2/3 y+5/3

x=-2/3 y+ 5/3

Answer:

The greatest common factor of 14x² - 4x is: 2x

Step-by-step explanation:

Given the expression

14x² - 4x

The first step is to factor out the greatest common factor from each term

14x² = 2 · 7 · 14 · x · x

4x = 2 · 4 · x

so

G.C.F = 2 · x

G.C.F = 2x

Therefore, the greatest common factor of 14x² - 4x is: 2x

Answer:

Step-by-step explanation:

m = y2-y1 / x2-x1

-7/2 = -5 - 2 / x -3

-7/2 = -7 / x-3

x-3 = -7 * -2/7

x-3 = 2

x=5

The number x = 27/7.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

If a line passes through two points (3 ,2) and (x, -5) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

And m = -7/2 (given)

Now,

-7/2 = (-5+2)/(x-3)

Using cross multiplication,

-7x + 21 = -6

x = 27/7

Therefore, the x is 27/7.

Answer:

Options 2 and 3

Step-by-step explanation:

If there are 2 boys and 5 altogether, means there are 3 girls. The ratio of boys to girls would be 2:3.

Look at all the first and second options as fractions to make things simpler. Simplify the fractions and see which ones are equivalent to 2/3

4/10 = 2/5 FALSE

8/12 = 2/3 TRUE

Options 3, 4, and 5 are comparing boys to all students, so whatever matches the ratio 2/5 is true.

10/25 = 2/5 TRUE

20/30 = 2/3 FALSE

9/15 = 3/5 FALSE

Answer:

The area of the triangle is 13.5 square units

Step-by-step explanation:

The easiest way to find the area of of a triangle is to find the area of rectangle surrounding it, and divide by two.

In this case, we can use the bottom line and the distance from that to the top point as the side lengths of our "rectangle"

The bottom line has a length of 9, and the distance from that line to the top point is 3.  We can say then that the area of the triangle is half of three times nine:

3 × 9 ÷ 2 = 3 × 4.5 = 13.5

So the total area of the triangle is 13.5 square units

Answer: GCF is 24 ^-^

Answer:

The first step to find the gcf of 72 and 96 is to list the factors of each number. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36 and 72. The factors of 96 are 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48 and 96. So, the Greatest Common Factor for these numbers is 24 because it divides all them without a remainder.

Question:

There are 33.8 fluid ounces in a litre. There are 128 fluid ounces in a gallon. About how many litres are in a gallon?

Is your estimate larger or smaller than the actual number of litres in a gallon? Explain how you know

Answer:

It is larger

Step-by-step explanation:

Given

[tex]33.8\ fl\ oz = 1\ litre[/tex]

[tex]128\ fl\ oz = 1\ gallon[/tex]

Required

Estimate number of litres in a gallon

[tex]33.8\ fl\ oz = 1\ litre[/tex]

[tex]128\ fl\ oz = 1\ gallon[/tex]

Cross Multiply

[tex]128\ fl\ oz * 1\ litre = 33.8\ fl\ oz * 1\ gallon[/tex]

[tex]128 * 1\ litre = 33.8* 1\ gallon[/tex]

Divide both sides by 33.8

[tex]\frac{128 * 1\ litre}{33.8} = \frac{33.8* 1\ gallon}{33.8}[/tex]

[tex]\frac{128 * 1\ litre}{33.8} = 1\ gallon[/tex]

[tex]3.78698224852\ litre = 1\ gallon[/tex]

Approximate

[tex]3.787\ litres = 1\ gallon[/tex]

The estimate is larger than the actual litres to gallon conversion because, in standard units of conversion;

[tex]3.785\ litres = 1\ gallon[/tex]

We solve the above question using Lowest Common Multiple Method.

Find and list multiples of each number until the first common multiple is found. This is the lowest common multiple.

Multiples of 6:

6, 12, 18, 24, 30, 36, 42

Multiples of 15:

15, 30, 45, 60

Therefore,

LCM(6, 15) = 30

Answer:

1,172.5cm²

Step-by-step explanation:

Total surface area of a box = 2(LW + WH + LH)

L is the length = 11.5cm

W is the width = 7cm

H is the height = 1.5cm

Substitute

TSA = 2(11.5(7) + 7(1.5) + (11.5)(1.5))

TSA = 2(80.5+10.5+17.25)

TSA = 2(117.25)

TSA = 234.5cm²

Hence  the total surface area of a stack of five such compact disc boxes will be 5(234.5) = 1,172.5cm²

Answer:

$5,400

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3.5%/100 = 0.035 per year,

then, solving our equation

I = 4000 × 0.035 × 10 = 1400

I = $ 1,400.00

The simple interest accumulated

on a principal of $ 4,000.00

at a rate of 3.5% per year

for 10 years is $ 1,400.00.

Answer:

The expression that represents the width of the rectangle is 4w + 9

Step-by-step explanation:

The formula of the area of the rectangle is A = length × width

Let us solve the question

∵ The area of a rectangle is 8w + 18 square feet.

∴  A = 8w + 18

∵ The HCF of 8 and 18 is 2

→ Divide each term of the area by 2 to get 2 as a common factor

∵ 8 ÷ 2 = 4 and 18 ÷ 2 = 9

∴ A = 2(4w + 9)

∵ The length of the rectangle is 2 feet

→ Substitute it in the formula of the area above

∵ A = 2 × width

∴ A = 2 width

→ Equate the two right sides of the area

∴ 2 width = 2(4w + 9)

→ Divide both sides by 2

∴ The width = 4w + 9

∴ The expression that represents the width of the rectangle is 4w + 9
