Answer:

Follows are the solution to this question:

Step-by-step explanation:

Given:

[tex]\to P+Q+R=180[/tex]

prove that [tex](\frac{\cos p}{\sin q \cdot \sin r}) +(\frac{\cos q}{\sin r \cdot \sin p})+ (\frac{\cos r}{\sin p \cdot \sin q})=2[/tex]

Solving the L.H.S part:

[tex]\to (\frac{\cos p}{\sin q \cdot \sin r}) +(\frac{\cos q}{\sin r \cdot \sin p})+ (\frac{\cos r}{\sin p \cdot \sin q})\\\\[/tex]

Solve the above value by taking L.C.M:

[tex]\to (\frac{\cos p \sin p+\cos q \sin q +\cos r \sin r}{ \sin p \cdot \sin q \cdot \sin r}) \\\\\to (\frac{\cos p \sin p+\cos q \sin q +\cos r \sin r}{ \sin p \cdot \sin q \cdot \sin r}) \\\\[/tex]

multiply the above value by [tex]\frac{2}{2}[/tex]:

[tex]\to (\frac{\cos p \sin p+\cos q \sin q +\cos r \sin r}{ \sin p \cdot \sin q \cdot \sin r}) \times \frac{2}{2} \\\\\to \frac{2 \cos p \sin p+ 2 \cos q \sin q + 2 \cos r \sin r}{2 \sin p \cdot \sin q \cdot \sin r} \\\\\therefore \sin 2A = 2 \sin A \cdot \cos A\\\\\because\\\\\to \frac{ \sin 2p+ \sin 2q + \sin 2r}{2 \sin p \cdot \sin q \cdot \sin r} \\\\\therefore \ \\ \bold{\sin 2p+ \sin 2q + \sin 2r= 4 \sin p \cdot \sin q \cdot \sin r}\\[/tex]

[tex]\to \frac{4 \sin p \cdot \sin q \cdot \sin r}{2 \sin p \cdot \sin q \cdot \sin r} \\\\\to \frac{2 \sin p \cdot \sin q \cdot \sin r}{ \sin p \cdot \sin q \cdot \sin r} \\\\\to 2[/tex]

So, L.H.S=R.H.S

Responder:

a) 2

b) 5

c) 4

d) 3

Explicación paso a paso:

Debemos encontrar el MCD de los siguientes números

a) 54, 76, 114

encontrar los factores primos de cada

54 = 2 * 3 * 3 * 3

76 = 2 * 2 * 19

114 = 2 * 2 * 2 * 2 * 3 * 3

De los factores anteriores, podemos ver que solo 2 es común a todos los factores, por lo tanto, el MCD de 54, 76 y 114 es 2

b) Para 35, 50 y 120

35 = 5 * 7

50 = 2 * 5 * 5

120 = 2 * 2 * 2 * 3 * 5

De los factores anteriores, podemos ver que solo 5 es común a todos los factores, por lo tanto, el MCD de 35, 50 y 120 es 5

c) Para 12, 16 y 20

12 = 2 * 2 * 3

16 = 2 * 2 * 2 * 2

20 = 2 * 2 * 5

De los factores anteriores, (2 * 2) es común a todos ellos, por lo tanto, el MCD de 12, 16 y 20 es 4

d) Para 56 y 120

56 = 2 * 2 * 2 * 7 = 8 * 7

120 = 2 * 2 * 2 * 3 * 5 = 8 * 3 * 5

De los factores anteriores, podemos ver que solo 8 es común a todos los factores, por lo tanto, el MCD de 56 y 120 es 8.

Por tanto, c = 8

Necesario

24 / c

= 24/8

= 3

Por tanto, el resultado de 24 / c es 3

Answer:

4

Step-by-step explanation:

we can see that the big square is twice as large as the small one

which makes x=4

The scale factor is 2. Then the value of the variable 'x' is 1 cm.

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.

The scale factor is given as,

SF = 14 / 7

SF = 2

Then the value of the variable 'x' is calculated as,

x = 8 / SF

x = 8 / 2

x = 4 cm

The scale factor is 2. Then the value of the variable 'x' is 1 cm.

Answer:

y=-4x-5

Step-by-step explanation:

Use the equation of the line formula, y=mx+b

since we know that the slope is -4, we just have to find b

plug the points into the equation, y=-4x+b

(3)=-4(-2)+b

simplify

3=8+b

subtract 8 from both sides

b=-5

plug b into the equation

y=-4x-5

Answer:

10,000

Step-by-step explanation:

Given that :

Decreed production level by the ministry :

Monthly widget production = 4000

Monthly gizmos production = 10,000

Deadweight loss for gizmos :

0.5(p2 - p1) * (Q2 - Q1)

0.5(70 - 60) * (10000 - 8000)

0.5 * 10 * 2000

10,000

Hence, Deadweight loss on gizmos is 10000

Deadweight loss occurs when equilibrium output is not attained.

Step-by-step explanation:

we start out with 50 flyers, then a volunteer takes away 5. This puts us now at 45 flyers, then another volunteer takes 18 flyers, leaving us at 27. We now have to equally share the remaining flyers with 3 volunteers. To do this we do 27 divided by 3, which gives us 9. Meaning we give 9 flyers to each of the remaining 3

Answer:To thank Mai five volunteers, Mai gave each of them the same number of stickers then she gave them each two more stickers altogether she gave them a total of 30 stickers

If a store raises a coffee mug's price from $6.25 to $8.77. The price increase was 40.32%. Option C is correct.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.

It is given that, A retailer marks up the price of a coffee mug from $6.25 to $8.77.

We have to find the percentage by which the price increase,

% increment = New rate - old rate / old rate × 100

% increment =(8.77 - 6.25)× 100

% increment =40.32%

Thus, if a store raises a coffee mug's price from $6.25 to $8.77. The price increase was 40.32%. Option C is correct.

[tex]\color{plum}\tt \: \bold{(A) 12x - 4 = 10x + 10 ; x = 7}[/tex]

Since these angles are corresponding angles and lie on two parallel lines, their value will be equal.

Which means :

[tex] = \tt12x - 4 = 10x + 10[/tex]

[tex] = \tt12x - 4 - 10x = 10[/tex]

[tex] = \tt12x - 10x = 10 + 4[/tex]

[tex] = \tt2x = 14[/tex]

[tex] =\tt x = \frac{14}{2} [/tex]

[tex] =\color{plum}\tt x = 7[/tex]

Thus, the value of x = 7.

Let's place 7 in the place of x and see if their value matches :

[tex] = \tt12 \times 7 - 4[/tex]

[tex] = \tt84 - 4[/tex]

[tex] = \tt80[/tex]

Thus, ∠12x - 4 = 80°

[tex] =\tt 7 \times 10 + 7[/tex]

[tex] = \tt70 + 10[/tex]

[tex] = \tt80[/tex]

Thus, ∠10x + 10 = 80°

Since the value of these two angles are equal, we can conclude that we have found out the correct measure of each angle.

Therefore, the correct option is - (A) 12x - 4 = 10x + 10; x = 7
