Answer:

x=35°   y= 75°   z = 70°

Step-by-step explanation:

Y = x+40   (known)

z = 2x    (known)

x + y + z = 180     (triangle property)

x + (x+40) + 2x = 180   (substitution)

4x + 40 = 180

4x = 140

x = 35

y = x + 40 = 75

z = 2x = 70

Answer:

£54.65

Step-by-step explanation:

Del sells his goods for £54.60 making a 9% loss how much did he pay for the good when he bought them?

We are to find the cost price.

Loss = Cost price - Selling price

Percentage loss =

(Cost price - Selling price/Cost price) × 100

Percentage loss = 9% = 0.09

Selling price = £54.60

Cost price = x

Hence:

0.09 = x - £54.60/x × 100

0.09 = 100(x - £54.60)/x

Cross Multiply

0.09x = 100(x - £54.60)

0.09x = 100x - 5460

100x - 0.09x = 5450

99.91x = 54.50

x = 5460 / 99.91

x = 54.649184266

Approximately, x = £54.65

Therefore, the cost price = £54.65

Answer: E C and A

Step-by-step explanation:

Answer:

Solution of the proportion: [tex]\frac{x-6}{4}=\frac{2}{4}[/tex] is x=8.

Step-by-step explanation:

We need to find solution of the proportion: [tex]\frac{x-6}{4}=\frac{2}{4}[/tex]

For solving the equation, first we will multiply both sides by 4

[tex]\frac{x-6}{4}=\frac{2}{4}[/tex]

[tex]4\times \frac{x-6}{4}=4\times \frac{2}{4}[/tex]

[tex]x-6=4(\frac{2}{4})[/tex]

Simplifying

[tex]x-6=2[/tex]

Adding 6 on both sides

[tex]x-6+6=2+6x=8[/tex]

So, solution of the proportion: [tex]\frac{x-6}{4}=\frac{2}{4}[/tex] is x=8.

Note: Kindly recheck your options as correct answer is x =8.

Answer:

Yes they are equivalent

Answer:

b is the correct answer

y=a(x+n)^2+k

vertex: -b/2a 18/2=9

y=1(x-9)^2

k=9^2-18(9)+52= 81-162+52=-29

y=(x-9)^2-29

Answer:

Una persona necesitará 2 horas y 30 minutos de viaje en bicicleta para quemar el contenido kilocalórico de cinco galletas.

Step-by-step explanation:

De acuerdo con este problema, la cantidad de calorías que se quema es directamente proporcional al tiempo de viaje en bicicleta. Si sabemos que una galleta aporta 150 kilocalorías, entonces 5 galletas equivalen a 750 kilocalorías.

Por regla de tres simple calculamos el tiempo requerido para quemar 750 kilocalorías:

[tex]x = 30\,min \times \frac{750\,kcal}{150\,kcal}[/tex]

[tex]x = 150\,min[/tex]

Es decir, una persona necesitará 2 horas y 30 minutos de viaje en bicicleta para quemar el contenido kilocalórico de cinco galletas.

Answer:

Step-by-step explanation:

A or C

Answer:

The solution to the system of equations represented by these two lines is:

Hence, option C i.e. (2, 0) is correct.

Step-by-step explanation:

Please note that the point of intersection between two lines is the solution of the system of equations.

From the graph, it is clear that two lines intersect at x = 2 and y = 0.

In other words, the point of intersection of the two lines is:

(x, y) = (2, 0)

Therefore, the solution to the system of equations represented by these two lines is:

Hence, option C i.e. (2, 0) is correct.

Answer:

See Explanation

Step-by-step explanation:

Your question is incomplete, as the equations or graph or table(s) were not given.

However, I'll give a general way of solving this.

Take for instance, the equations are:

[tex]y = \frac{4}{3}x - 1[/tex]

[tex]y = \frac{2}{3}x - \frac{1}{2}[/tex]

To do this, we start by equating both equations.

[tex]y = y[/tex]

i.e.

[tex]\frac{4}{3}x - 1= \frac{2}{3}x - \frac{1}{2}[/tex]

Collect Like Terms

[tex]\frac{4}{3}x - \frac{2}{3}x= 1 - \frac{1}{2}[/tex]

Take LCM

[tex]\frac{4x- 2x}{3}= \frac{2 - 1}{2}[/tex]

[tex]\frac{2x}{3}= \frac{1}{2}[/tex]

Cross Multiply

[tex]2x * 2 = 3 * 1[/tex]

[tex]4x = 3[/tex]

Make x the subject

[tex]x = \frac{3}{4}[/tex]

Substitute 3/4 for x in [tex]y = \frac{4}{3}x - 1[/tex]

[tex]y = \frac{4}{3} * \frac{3}{4} - 1[/tex]

[tex]y = 1 - 1[/tex]

[tex]y = 0[/tex]

Hence:

[tex](x,y) = (\frac{3}{4},0)[/tex]

Answer:

The value of sin Ф is [tex]\frac{5}{13}[/tex]

Step-by-step explanation:

In quadrant II, the value of

Let us solve the question

∵ sin²Ф + cos²Ф = 1

∵ cos Ф = [tex]\frac{-12}{13}[/tex]

→ Substitute it in the identity above

∴ sin²Ф + ([tex]\frac{-12}{13}[/tex])² = 1

∴ sin²Ф + [tex]\frac{144}{169}[/tex] = 1

→ Subtract [tex]\frac{144}{169}[/tex] from both sides

∵ sin²Ф + [tex]\frac{144}{169}[/tex]  - [tex]\frac{144}{169}[/tex]  = 1 - [tex]\frac{144}{169}[/tex]

∴ sin²Ф = [tex]\frac{25}{169}[/tex]

→ Take the square root of both sides

∵ √(sin²Ф)= ± [tex]\sqrt{\frac{25}{169}}[/tex]

∴ sin Ф = ± [tex]\frac{5}{13}[/tex]

∵ Ф is in quadrant II

∴ sin Ф is a positive value

∴ sin Ф = [tex]\frac{5}{13}[/tex]

∴ The value of sin Ф is [tex]\frac{5}{13}[/tex]

Step-by-step explanation:

Answer:

option 2

Step-by-step explanation:

Using the cosine and sine ratios in the right triangle and the exact values

cos30° = [tex]\frac{\sqrt{3} }{2}[/tex] , sin30° = [tex]\frac{1}{2}[/tex]

cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{20\sqrt{3} }[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

2x = 60 ( divide both sides by 2 )

x = 30

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

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{y}{20\sqrt{3} }[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2y = 20[tex]\sqrt{3}[/tex] ( divide both sides by 2 )

y = 10[tex]\sqrt{3}[/tex]

Answer:

The correct option is A.

Step-by-step explanation:

It is given that  DEFG is a parallelogram.

Draw the diagonals DF and EG. Place point H where DF and EG intersect.

In triangle HGD and HEF

,

∠HGD ≅ ∠HEF                            (Alternate Interior angle)

∠HDG ≅ ∠HFE                      (Alternate Interior angle)

By the definition of a parallelogram, the opposite sides of a parallelogram are congruent.

DG ≅ EF                                      (Opposite sides of parallelogram)

According to ASA postulate :

two triangles are congruent if any two angles and their included side are equal in both triangles.

So, by using ASA criterion for congruence we get,

ΔDGH ≅ ΔFEH

Since corresponding sides of congruent triangles are congruent, therefore

GH ≅ EH                      (CPCTC)

DH ≅ FH                     (CPCTC)
