Answer:

2a + 3c + 4d

Step-by-step explanation:

This is the answer because:

1) Nothing further can be done to this equation since there are no like terms.

Therefore, the answer is 2a + 3c + 4d.

Hope this helps! :D

Answer:

  179/495

Step-by-step explanation:

When the repeating decimal starts at the decimal point, the repeating digits can be turned into a fraction by putting them over the same number of 9s. That is, 0.61616161... is equivalent to 61/99.

Here, the repeating part is 1/10 that value, so is 61/990. This is added to the non-repeating part, which is 0.3 = 3/10.

Then the entire decimal is ...

  0.361_61 = 3/10 + 61/990 = (297 +61)/990 = 358/990 = 179/495

Answer:

Concept: Statistics

Answer and Step-by-step explanation:

It's very easy.

If you have two shapes, let's say triangles, the shapes are said to be similar if the corresponding angles are equal. For instance a triangle ABC with angles A = 45, B = 45 and C = 90 if there is another triangle PQR with angles P = 45, Q = 45 and R = 90, we say triangle ABC and triangle PQR are similar because their corresponding angles are equal.

Two triangles are said to be congruent if they are exactly the same in angles and size. All congruent shapes are similar but not all similar shapes are congruent.

To find area of similar shapes, we need what we call the scale factor of the enlargement.

If we have two similar shapes where by one is an enlargement of the other. Let's say the enlargement is in ratio 2:1. This ratio 2:1 is what we call scale factor. If we want to find the area of one shape given the area of a similar one to it, we make use of

Area = (scale factor)². For instance if we have two similar triangles, the area of the bigger is 16cm² and the scale factor is 2:1, we can find the area or the smaller by:

(2/1)² = 16/X = 4/1 = 16/X

4x = 16 and x = 4.

To find volume we use:

Volume = (scale factor)³ and the process is the same.

Answer:

$240

Step-by-step explanation:

Answer:

The correct answer is D) 200

Step by step explanation:

Let x be the number:

Then,

→15/100(x)=30

→3/20(x)=30

→3x/20=30

→3x=20⋅30

→3x=600

→x=600/3=200

Hope it helps!

Answer:

D 200

Step-by-step explanation:

Let the number we are find be x. We can write this as an equation:

30 = 15%*x = (15/100)x

Multiplying by 100/15 on both sides to isolate x:

x = 30(100/15) = 2(100) = 200

Therefore, 200 is our answer. I hope this helps! :)

Answer:

The Width of each side of the bookmark in centimeters = 5cm

Step-by-step explanation:

A bookmark shaped like a rectangle has a total perimeter of38cm the length of the one of its sides is 14 what is the width of each side of the bookmark in centimeters

The formula for perimeter fo a rectangle =

P = 2L + 2W

Where L = Length

W = Width

Hence: From the above question:

38cm = 2 × 14 cm + 2 W

38cm = 28cm + 2W

2W = 38cm - 28cm

2W = 10cm

W = 10cm/2

W = 5cm

Hence, the Width of the rectangle(each side of the bookmark in centimeters) = 5cm

Step-by-step explanation:

Answer: 6 in. x 10 in.

Step-by-step explanation:

Nash is making a framed enlargement of a Mary Cassatt postage stamp to present to a retired postmaster.

1. The scale of enlargement is 2 inches to 1 centimeter.

2. The actual length of the stamp = 3 centimeters

3. The length of frame =   2 x 3 = 6 inches

4. The actual width of the stamp = 5 centimeters

5. The width of frame =  2 x 5 = 10 inches

Conclusion: Because of this, the dimensions for the scale picture would be 6 by 10 inches

See the attachment below, co-interior angles lie at the same side of the transversal, or the line that crosses between the two parallel lines.

So if you are finding the co-interior angle of ∠AGH, then it is ∠CHG.

They are also supplementary angles and will add up to 180°.

Step-by-step explanation:

It's given that A = 30° . Lets find the sin , cos & tan of A

⇒ [tex]\sin A=\sin30 = \frac{1}{2}[/tex]

⇒ [tex]\cos A = \cos 30 = \frac{\sqrt{3} }{2}[/tex]

⇒[tex]\tan A = \tan 30 = \frac{1}{\sqrt{3} }[/tex]

Lets solve the LHS (Left Hand Side) :-

[tex]2(\sin A \times \cos A) = 2(\frac{1}{2} \times \frac{\sqrt{3} }{2}) = \frac{\sqrt{3} }{2}[/tex]

Now lets solve the RHS (Right Hand Side) :-

[tex]\frac{2\tan A}{1+\tan ^{2}A } = \frac{2 \times \frac{1}{\sqrt{3} } }{1 + (\frac{1}{\sqrt{3} } )^{2} } = \frac{2}{\sqrt{3} } \div ( 1 + \frac{1}{3} ) = \frac{2}{\sqrt{3} }\div \frac{4}{3} = \frac{2}{\sqrt{3} } \times\frac{3}{4} =\frac{\sqrt{3} }{2}[/tex]

∴ LHS = RHS ( Proved )

Answer:

Step-by-step explanation:

Unfortunately you did not post all the options, so .... now just figure it out ...

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identities

tan a = [tex]\frac{sina}{cosa}[/tex], cot a = [tex]\frac{cosa}{sina}[/tex]

sec a = [tex]\frac{1}{cosa}[/tex], cosec a = [tex]\frac{1}{sina}[/tex]

Consider the left side

tana + cota

= [tex]\frac{sina}{cosa}[/tex] + [tex]\frac{cosa}{sina}[/tex]

= [tex]\frac{sin^2a+cos^2a}{cosasina}[/tex]

= [tex]\frac{1}{cosasina}[/tex]

= [tex]\frac{1}{cosa}[/tex] × [tex]\frac{1}{sina}[/tex]

= seca . coseca

= right side , thus proven

Step-by-step explanation:

gradient/slope = 3

y-intercept

2x - 3y = 4

3y = 2x - 4

y = 2/3x - 4/3

so y-intercept is double -4/3 so... -4/3x2 = -8/3

the equation of the line is

y = 3x - 8/3 or 9x - 3y = 8

Answer:

3y=2x-8

Step-by-step explanation:

when y intercept x=0

2(0)-3y=4

-3y=4

y=-4/3

when x intercept y=0

2x -3(0)=4

2x =4

x=2

point (2,-4/3)

gradient

-3y=-2x +4

y=2x/3-4/3

gradient=2/3

equation

y+4/3=2/3(x-2)

3y+4=2x-4

3y=2x-8

Step-by-step explanation:

Answer:

t=10

Step-by-step explanation:

4=t/2.5

4=t/25/10

divide 25and10 by 5=5/2

4=t/5/2

4=t×2/5

multiply both sides of the equation by 5

5×4=t×2/5×5

20=t×10/5

20=t×2

Answer:

cotθ = [tex]\frac{4}{3}[/tex]

Step-by-step explanation:

Using the trigonometric identity

cot x = [tex]\frac{cosx}{sinx}[/tex], then

cotθ = [tex]\frac{-0.8}{-0.6}[/tex] = [tex]\frac{8}{6}[/tex] = [tex]\frac{4}{3}[/tex]
