The cost of a phone is reduced by 20%. The new cost is $70.40. What was the original price?

Answer:

x = 19

Step-by-step explanation:

x-42+x-32+180-x+17 = 180

3x +123 = 180

3x = 57

x=19

x = 91.

Putting 91 into the two equations inside the triangle makes the angles 59 and 49, and makes the outside angle 108. Those two angles must add and equal the outside angle, and they do, meaning x = 91.

Answer:

Step-by-step explanation:

take 52 degree as reference angle

using tan rule

tan 52=opposite/adjacent

1.27=x/21

1.27*21=x

26.67=x

26.9=x

Answer:

C

Step-by-step explanation:

Answer:

a = 65°

(what's missing for a half turn)

c = 30°

(bc same angle as upper left)

b = 85°

(bc a+b+c must be 180° in sum, as always in triangles)

please brainliest

Answer:

a = 45

b = 105

c = 30 .

Step-by-step explanation:

a +  135 = 180  {Linear pair}

         a = 180 - 135

a = 45

d = 30    {Vertically opposite angles}

WA // YZ

c = d   { Alternative interior anlges}

c = 30

a +  b+ c = 180  {Angle sum property of triangle}

45 + b + 30 = 180

       b + 75 = 180

b = 180 -75

b = 105

Answer:

The mark up is $2.20 and the new price of each T-shirt is $6.20.

Step-by-step explanation:

Before we find the new price of each T-shirt we must find the markup (by how much were raising the price).

The problem states each T-shirt costs $4.00, but then marks up the price of each by 55%.

Step 1 would be to find 55% of $4.00.

0.55 * 4 = 2.2

So that is the mark up, the price is going up by $2.20. To find the new price of each T-shirt, you take that $2.20 and add it to the original $4.00.

$4.00 + $2.20 = $6.20

So the mark up is $2.20 and the new price of each T-shirt is $6.20.

Answer:

3C1 * 7C6 * 3C2 * 3C3

Step-by-step explanation:

Dado que solo tres saben cómo conducir, de estos tres uno estará en la posición de conducción, por lo tanto, el número de formas en que este conductor puede elegir entre estos tres es 3C1 * 7C6

Ahora, 2 de los conductores se sentarán en los asientos de los pasajeros junto con otros tres 3C2 * 3C3

Número total de oportunidades = 3C1 * 7C6 * 3C2 * 3C3

Option 'D' is the correct option.

The correct diagram for Beyunka creating is given in option D.

What is Right triangle?

When an angle of a triangle is measure 90 degree then the triangle is called a right triangle.

Given that;

Beyunka is creating a diagram to prove that certain triangle is a right triangle.

Since, The right triangle is satisfy the Pythagoras theorem.

Now, By option D;

Let sides of a triangle are,

Hypotenuse (H) = c

Perpendicular side (P) = a

Then, The base of the right triangle = √H² - P² = √c² - a²

And, All other diagrams are not satisfy the Pythagoras theorem.

Thus, The correct diagram for Beyunka creating is given in option D.

Answer:

y=1/3x+3

Step-by-step explanation:

the general equation for a straight line is y=mx+c.where c is the y cut therefore the y cut on our graph is at (0,3)therefore c is 3

we then find the gradient which is "m" on our equation using the formula m=y2-y1/x2-x1

then we substitute the m and c then tha is the equation.

Hello! answer: a = 8

Step-by-step explanation:

2.4 × 8 = 19.2

19.2 + 8 = 27.2 therefore a = 8 hope that helps!

Answer:

a = 8

Step-by-step explanation:

2.4a + 8 = 27.2

2.4a + 8 - 8 = 27.2 - 8

2.4a = 19.2

2.4a ÷ 2.4 = 19.2 ÷ 2.4

a = 8
