Step-by-step explanation:

100 + 55 = 155

180 (Interior Angles of a Triangle Rule) - 155 = 25

Answer:

6 + (t x 2) = 33

T = Ticket Cost

6 - 6 + (t x 2) = 33 - 6

t x 2 = 27

t x 2/2 = 27/2

t = 13.5

Each ticket cost 13.50$

Answer:

Angle A = 30.8

Angle B = 33.2

Step-by-step explanation:

180 - 116 = 64  

This means that the other two angles need to add up to 64.

I just plugged in numbers until it worked.

I got that x = 14.6

2x + 4

2(14.6) + 4

29.2 + 4

33.2

3x - 13

3(14.6) - 13

43.8 - 13

30.8

Those are your angles. To make sure they are correct you just need to add up all the angles and make sure that they equal to 180.

116 + 33.2 + 30.8 =

180

Answer:

933mounths=77years and 9 mounts

Answer:

[tex]77\frac{3}{4}[/tex] years = 933 months

77.75 years = 933 months

Step-by-step explanation:

1 year = 12 months

y = 933 months

[tex]\frac{1}{12}= \frac{y}{933}[/tex]

12 × y = 933 × 1

12y = 933

12y ÷ 12 = 933 ÷ 12

y = 77.75

Answer:

x = 51

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

x² = 45² + 24² = 2025 + 576 = 2601 ( take the square root of both sides )

x = [tex]\sqrt{2601}[/tex] = 51

Answer:

x = 51.

Step-by-step explanation:

The triple you require is 17-15-8

We have x-45-24

- that is three times each number in the triple.

So x = 3*17 = 51.

Answer:

m∠A = 30°

m∠B = 80°

m∠C = 70°

Step-by-step explanation:

By applying cosine rule in the given triangle,

b² = a² + c² - 2ac[cos(∠B)]

From the given triangle,

a = 14 m

b = 28 m

c = 24 m

(28)² = (14)² + (24)² - 2(14)(24)cos(B)

784 = 196 + 576 - 672cos(∠B)

cos(∠B) = 0.1786

∠B = [tex]\text{cos}^{-1}(0.1786)[/tex]

∠B = 79.71°

∠B = 80°

By applying sine rule in the given triangle,

[tex]\frac{\text{sinA}}{a}= \frac{\text{sinB}}{b}= \frac{\text{sinC}}{c}[/tex]

[tex]\frac{\text{sinA}}{14}= \frac{\text{sin(79.71)}}{28}= \frac{\text{sinC}}{24}[/tex]

[tex]\frac{\text{sinA}}{14}= \frac{\text{sin(79.71)}}{28}[/tex]

[tex]\text{sinA}= \frac{\text{sin(79.71)}\times 14}{28}[/tex]

sinA = 0.491958

A = 29.47°

A ≈ 30°

By applying triangle sum theorem,

m∠A + m∠B + m∠C = 180°

30° + 80° + m∠C = 180°

m∠C = 70°

Answer:

125 units^3

Step-by-step explanation:

Volume is l*w*h = V. A cube has all equal sides so wecan divide 1000 by 3 and get our side lengths.

You then divide the sides by 2 because the question says the second cubes sides are half the size

5*5*5 = 125

The volume of the second cube is 125 units³.

In mathematics, ‘Volume’ is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface.

Given that a cube has volume 1000 units³ and another smaller cube has smaller volume has side only half as long.

We need to find the volume of the second cube,

So, let the side of the first cube be x,

We know that the volume of a cube = side³

Therefore,

x³ = 1000

x = ∛1000

x = 10 units

Therefore, the second cube will have a side of 10/2 = 5 units

Volume of second cube = 5³ = 125 units³.

Hence the volume of the second cube is 125 units³.

Step-by-step explanation:

Given that,

The area of the square base, A = 36 cm²

Slant height, s = 12 cm

We need to find the lateral area of the regular pyramid. The formula is :

[tex]S=A+\dfrac{1}{2}p\times s[/tex]

Where

A is the area of base

p is perimeter of base

s is slant height

Area of square, A = side²

So,

[tex]side=6\ cm[/tex]

Put values in the above formula.

[tex]S=36+\dfrac{1}{2}\times 4\times 6\times 12\\\\=36+144\\\\=180[/tex]

So, the lateral area of the regular pyramid is equal to 180 cm².

Answer:

25 cm

Step-by-step explanation:

[tex]C=2\pi r[/tex] where r is the radius of the circle

Plug in the given radius (4 cm)

[tex]C=2\pi (4)\\C=8\pi\\C=25[/tex]

Therefore, the circumference of the opening is approximately 25 cm.

Marketing entrepreneurs choose a marketing niche first to prepare to launch their business. Thus, option B is correct.

The portion of a market that a particular product is targeted toward is called a niche market. The product's market niche determines its price range, level of production, target demographics, and feature set that is intended to address a particular market need. Additionally, it is a small market sector. A product or service may occasionally be created specifically to meet the needs of a niche market.

Not all products can be classified by their market niche. The highly specialised niche market competes against numerous super companies and strives to remain viable. Even well-known companies develop products for specific markets; Hewlett-Packard produces separate machines in addition to all-in-one printing, scanning, and faxing units that are aimed at the home office market.
