Step-by-step explanation:

Use the “ %/100 = is/of ” method

45          ?

__    =     __

100          45

cross mutilps 45(45) = 2,025

then divide 2,025 by 100 = 20.25

Answer:

(a) 33.7 cm

(b) 79.25 cm²

Step-by-step explanation:

(a)

Find the perimeter of the semicircle (circumference ÷ 2).

10 cm is the diameter of the semicircle.

The perimeter of the semicircle

= (10 × 3.14) ÷ 2

= 31.4 ÷ 2

= 15.7 cm

The perimeter of the shape

= 15.7 + 10 + 4 + 4

= 33.7 cm

(b)

Find the area of the circle then divide to 2

The formula of the area of a circle

= πr²

The radius of the circle

= 10 ÷ 2

= 5 cm

The area of the semicircle

= (3.14 × 5²) ÷ 2

= 78.5 ÷ 2

= 39.25 cm²

The area of the rectangle

= 4 × 10

= 40 cm²

The area of the shape

= 39.25 + 40

= 79.25 cm²

Step-by-step explanation:

Angle 1 2 and 3 are angles that are in a triangle and all the angles in a triangle always add up to 180

so <1 +<2 +<3=180

When flipping, the y-levels of E' and F' do not change, meaning that as they are transferred across the y-axis, they keep their parallel to the original points.

Answer:

53.57%

Step-by-step explanation:

Answer:

53.57%

Step-by-step explanation:

Answer:

Step-by-step explanation:

This figure is called a cyclic quadrilateral. The vertices of all sides lie on a circle.

That's property one.

Property 2 is that the opposite angles add to 180 degrees.

6y - 4 + 5y - 3 = 180 is the y angles. Combine like terms.

11y - 7 = 180                                         Add 7 to both sides.

11y - 7 + 7 = 180 + 7

11y = 187                                              Divide by 11

y = 187/11

y = 17

H = 17 * 6 - 4

H = 102 - 4

H =  98

F = 5y - 3

F = 5*17 - 3

F = 85 - 3

F = 82

=====================

11x + 8 +  8x + 1 = 180

19x + 9 = 180

19x = 171

x = 171/19

x = 9

E = 9*11 + 8

E = 99+8

E = 107

G = 8*9 + 1

G = 72 + 1

G = 73

Answer: [tex]432\pi \text{ cubic centimeters}[/tex] or [tex]1356.48\text{cubic centimeters}[/tex]

Step-by-step explanation:

Volume of right circular cylinder = [tex]\pi r^2 h[/tex]

Given: Radius = 6 centimeters

Height = 12 centimeters

Then, the volume of this cylinder = [tex]\pi (6)^2 \times (12)= 432\pi \text{ cubic centimeters}[/tex]

Hence, the volume of this cylinder = [tex]432\pi \text{ cubic centimeters}[/tex]

At [tex]\pi=3.14[/tex]

The volume of this cylinder[tex]=432\times3.14=1356.48\text{cubic centimeters}[/tex]

Answer:

Centre = (2, -3)

radius = 5units

Step-by-step explanation:

The standard form of a circle is expressed as;

x²+y²+2gx+2fy+c = 0

Centre = (-g, -f)

radius r = √g²+f²-c

Given the equation;

x²+y²-4x+6y-12 = 0

Compare

2gx = -4x

2g = -4

g = -2

Similarly;

2fy = 6y

2f = 6

f = 3

Centre = (-(-2), -3)

Centre = (2, -3)

Radius = r = √(-2)²+3²+12

r = √4+9+12

r = √25

r = 5 units

Water is the Adjacent of this right triangle. 350 yards is the length of the Hypotenuse. We have given angle B, 40 degrees.

_________________________________________________________

According to SOH CAH TOA, we use CAH (cosineΘ = adjacent/hypotenuse).

cosine40 = x/350

[multiply both sides by 350]

350 · cosine40 = x

[put calculator in degree mode]

x ≈ 268 yards

So, the distance across the water from sailboat to the island is 268 yards.

_________________________________________________________

Let's use pythagorean theorem since we already know the adjacent and hypotenuse to find the opposite (opposite is also known as height).

a^2 + b^2 = c^2

a^2 + (268)^2 = (350)^2

a^2 + 71824 = 122500

a^2 = 122500 - 71824

a^2 = 50676

[square both sides]

[tex]\sqrt{a^2}[/tex] = [tex]\sqrt{50676}[/tex]

a = [tex]\sqrt{50676}[/tex]

a ≈ 225

So, the height, opposite, of the lighthouse is 225 yards.

Answer:

14000

Explaination:

spwithvat = sp without vat + 13% of sp without vat

let, sp without vat be x.

sp with vat= x + 13% of x.

or, 13447 = x + 13/100 × x

or, 1344700 = 113x

or, x= 1344700/113

x = 11900

Let, mp be y.

sp with vat = mp - 15% of mp

or, 11900 = y - 15/100 × y

or, 1190000 = 85y

or, y= 1190000/85

y= 14000

Answer:

Distribute the term outside of the parenthesis, multiply each term inside the parenthesis by the term outside of the parenthesis.

(12)(2x) - (12)(3y) + (12)(4)

24x - 36y + 48

Answer: t=8

Step-by-step explanation:

The highest ticket price that they can charge in order to not lose money on the event will be $8.16.

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

Sally's secondary school is arranging their spring melodic. The income, R, is created still up in the air by the capability R(t) = -33t² + 360t, where t addresses the cost of a ticket. The creation cost, C, of the melodic is addressed by the capability C(t) = 700 + 5t.

The highest ticket price that they can charge in order to not lose money on the event will be given as,

C(t) = R(t)

700 + 5t = -33t² + 360t

33t² - 355t + 700 = 0

Solve for 't', then we have

t = [-(-355) ± √((-355)² - 4 × 33 × 700)] / (2 × 33)

t = [355 ± 183.37] / 66

t = 5.378 ± 2.778

t = 5.378 + 2.778, 5.378 - 2.778

t = 8.16, 2.60

Answer:

35

Step-by-step explanation:

The measure of an inscribed angle whose endpoints are points S and T will be 35°.

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

The central angle is double the angle at the periphery that was subtended by the same chords.

The central angle of arc ST is 70°.

The measure of an inscribed angle whose endpoints are points S and T is given by the half of the central angle of arc ST. Then we have

Inscribed angle = 70° / 2

Inscribed angle = 35°

The measure of an inscribed angle whose endpoints are points S and T will be 35°.
