Answer:

The answer is below

Step-by-step explanation:

Triangles are polygons with three sides and three angles. Types of triangles are isosceles, equilateral, scalene and right angled triangles.  

Trigonometric identities are equations that uses trigonometric functions to show the relationship between the angles in a right angle triangle and the sides of the right angled triangle.

If θ be an acute angle in a right angled triangle, hyp. is the hypotenuse side of the angle, opp. is the opposite side to the angle and adj. is the adjacent side to the angle, then:

sinθ = opp. / hyp.v;  cosθ = adj. / hyp. ; tanθ = opp. / adj.

Answer: 3

Step-by-step explanation:

48 divided by 16 is 3

The number of pounds expected to use this month is 3 pounds.

It is the conversion of one unit to another unit with its standard conversion.

Example:

1 hour = 60 minutes

1 minute = 60 seconds

1 km = 1000 m

We have,

16 oz = 1 lb

Multiply 3 on both sides.

48 oz = 3 lb

Thus,

3 pounds of wood is in 48 oz.

Answer:

x = 16

Step-by-step explanation:

For the triangle to be isosceles then AB = CB , that is

5x - 9 = 4x + 7 ( subtract 4x from both sides )

x - 9 = 7 ( add 9 to both sides )

x = 16

Answer:

I think its B

Step-by-step explanation:

Let's solve your equation step-by-step.

3(2x−5)=4(x+3)

Step 1: Simplify both sides of the equation.

3(2x−5)=4(x+3)

(3)(2x)+(3)(−5)=(4)(x)+(4)(3)(Distribute)

6x+−15=4x+12

6x−15=4x+12

Step 2: Subtract 4x from both sides.

6x−15−4x=4x+12−4x

2x−15=12

Step 3: Add 15 to both sides.

2x−15+15=12+15

2x=27

Step 4: Divide both sides by 2.

The equation is equivalent to given equation is 2x=27. Therefore, option B is the correct answer.

Algebraic equations with equivalent solutions or roots are called equivalent equations. An analogous equation is one that is created by adding or removing the identical quantity or expression from both sides of a given equation. An equation is equivalent if both sides are multiplied or divided by the same non-zero value.

The given equation is 3(2x-5)=4(x+3).

Now, 6x-15=4x+12

6x-4x=12+15

2x=27

The equation is equivalent to given equation is 2x=27. Therefore, option B is the correct answer.

Determine the number of tiles in 11 points

Represent this with x. So, we have:

[tex]1\ tile = \frac{1}{3}\ points[/tex]

[tex]x = 11\ points[/tex]

Cross Multiply

[tex]x * \frac{1}{3} = 11 * 1[/tex]

Answer:  2.815 kilograms

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

Work Shown:

1 layer = 0.5 kg

5 layers = 5*(0.5 kg) = 2.5 kg

icing = 15 g = 15/1000 = 0.015 kg

1 candle = 100 g = 100/1000 = 0.1 kg

3 candles = 3*(0.1 kg) = 0.3 kg

------------------------

The five layers combine to 2.5 kg. On top of that we have 0.015 kg of icing, and then finally the three candles add 0.3 kg more weight.

The total weight is therefore: 2.5+0.015+0.3 = 2.815 kilograms

Answer:

it's 4 on edge

Step-by-step explanation:

I got it right

The value is in the domain of f(x) is 4, the correct option is C.

The domain of a function is defined as the set of all the possible input values that are valid for the given function.

The range of a function is defined as the set of all the possible output values that are valid for the given function.

We are given that;

f(x) =-2x + 3,0 < x < 4

Now,

The domain of a function is the set of all possible input values for which the function is defined. In this case, the function f(x) is defined by two different expressions depending on the value of x. The first expression, 2x + 5, applies when -6 < x < 0. The second expression, -2x + 3, applies when 0 < x < 4. Therefore, the domain of f(x) is the union of these two intervals:

Domain of f(x) = (-6, 0) U (0, 4)

Therefore, by the domain the answer will be 4.

Answer: 9.6 days

Step-by-step explanation:

Rashid can do a piece of work in 8 days. Rashid work rate will then be:

= 1/8 owe day.

Tipu can finish in 12 days. Tipu's work rate will be: = 1/12 owe day.

Their work rate together will then be:

= 1/8 + 1/12

= 3/24 + 2/24

= 5/24

From the calculation, together they will finish the work in:

= 1 ÷ 5/24

= 1 × 24/5

= 24/5 days

= 4.8 days

Busy since they are working on alternate days, then this will be multiplied by 2 which will be:

= 4.8 × 2

= 9.6 days
