Raquel wants to buy a cellphone that costs ₱ 4,998.50. She has ₱ 3,536.75 now. How much more money does she need to buy the cellphone?

Answer:

x = 15

Step-by-step explanation:

Using the Altitude- on- Hypotenuse theorem

(leg of large Δ )² = (part of hypotenuse below it ) × ( whole hypotenuse )

x² = 9 × (9 + 16) = 9 × 25 = 225 ( take square root of both sides )

x = [tex]\sqrt{225}[/tex] = 15

Answer:

I did this quickly, so please check the logic.

I find x = 15

Step-by-step explanation:

See attached image.  Note that I've defined 3 triangles and their Pythagorean equations.  I also define a third line, RQ, as z.  Rearrange the equations and substitute in a way that allows elimination of all variables except x.

Based on given conditions,

[tex]a²b + 3 ab - (-5 a²b - 9 ab) [/tex]

[tex]→a²b + 3 ab + 5 a²b + 9 ab[/tex]

[tex]→(a²b + 5 a²b) + (3ab + 9 ab[/tex]

Now collecting the coefficients and adding them,

[tex](1 + 5)a²b + (3 + 9)ab[/tex]

[tex]→6 {a}^{2}b + 12ab[/tex]

Hence, the 6a²b + 12ab should be added.

Answer:

60.96

Step-by-step explanation:

127 times 0.48

Answer:

Simplifying the same denominators first:

16/5 - 13/5 = 3/5

So, we're brought down to:

3/5 + 30/7 + 3/2

35 goes into 5 and 7, so I'll simply 3/5 + 30/7 next -

7 x (3/5) to get 21/35

5 x (30/7) to get 150/35

Now add the two to get 171/35

(150+21=171)

Finally find a common denominator for 35 and 2.

(35x2=70)

2 x (171/35) --> 342/70

35 x (3/2) -->  105/70

Add up 342+105 to get 447 & put over 70.

Answer is 447/70

(It can't be simplified any further than this.)

Answer:

$20

Step-by-step explanation:

if one ound = 16 ounces then you would do 1.25x16 witch equals $20

If oranges were 1.25$ per pound. then the cost to buy x pounds of oranges would be 1.25x $.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

If oranges were 1.25$ per pound. We need to find the cost to buy x pounds of oranges.

The cost of oranges per pound = 1.25$

The cost of oranges x pound = 1.25$ × x

                                                 = 1.25x $

Thus, The cost to buy x pounds of oranges would be 1.25x $.

Answer:

B

Step-by-step explanation:

x² - 12x + 11 = 0 ( subtract 11 from both sides )

x² - 12x = - 11

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 6)x + 36 = - 11 + 36

(x - 6)² = 25 ( take square root of both sides )

x - 6 = ± [tex]\sqrt{25}[/tex] = ± 5 ( add 6 to both sides )

x = 6 ± 5

Then

x = 6 - 5 = 1 ⇒ (1, 0 )

x = 6 + 5 = 11 ⇒ (11, 0 )

Answer:

y=0x-7 or y=-7

Step-by-step explanation:

Hi there!

We want to write the equation of the line that passes through the point (-6, -7), but that also has a slope of 0

There are many ways to write the equation of the line; one of the most common ways is to use slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

As we are already given the slope of this line, we can immediately plug it into the equation as m

So substitute 0 as m in the equation:
y=0*x+b

Multiply

y=0x+b

We can also rewrite it as y=b, but for right now, y=0x+b will be helpful for our calculations

We need to find b now.

As the equation passes through the point (-6, -7), we can use it to help solve for b

Substitute -6 as x and -7 as y:

-7=0(-6)+b

Multiply

-7=0+b

Simplify

-7=b

Substitute -7 as b into the equation.

y=0x-7, or y=-7

In essence, the two triangles made by the radii and the twin tangent lines are congruent by SSS or even for right-triangles congruence by LL.

Applying the tangents theorem, the arc measures are:

Arc EG = 140°

Arc EF = 120°

Arc FG = 100°

The tangents theorem states that a tangent to a circle forms a right angle (90 degrees) at the point of tangency, and also, if two tangents meet at point outside a circle, both tangents are equal.

Using the tangent theorem, we would find the central angles opposite arc EF, FG, and GE which are all the same measure as their central angles.

Let the center of the circle be point O.

m∠EOG = 2[180 - m∠PEG + m∠EOP)] (central angle opposite to arc EG)

Substitute

m∠EOG = 2[180 - 90 + 1/2(40)]

m∠EOG = 140°

Arc EG = m∠EOG = 140°

Arc EG = 140°

m∠EOF= 2[180 - m∠QFO + m∠FQO)] (central angle opposite to arc EF)

Substitute

m∠EOF = 2[180 - 90 + 1/2(60)]

m∠EOF = 120°

Arc EF = m∠EOF = 120°

Arc EF = 120°

m∠FOG = 2[180 - m∠RFO + m∠FRO)] (central angle opposite to arc FG)

Substitute

m∠FOG = 2[180 - 90 + 1/2(80)]

m∠FOG = 100°

Arc FG = m∠FOG = 140°

Arc FG = 100°

Therefore, applying the tangents theorem, the arc measures are:

Arc EG = 140°

Arc EF = 120°

Arc FG = 100°

Answer:

105/120

48/120

50/120

Step-by-step explanation:

8, 5, 12

8 = 2³

5 = 5

12 = 2² × 3

LCD = 2³ × 3 × 5 = 8 × 3 × 5 = 120

120/8 = 15

7/8 = (7 × 15)/(8 × 15) = 105/120

120/5 = 24

2/5 = (2 × 24)/(5 × 24) = 48/120

120/12 = 10

5/12 = (5 × 10)/(12 × 10) = 50/120

Step-by-step explanation:

sum of two interior angles is equal one exterior angle....this implies that,

6x + 15x-12 = 19x+2.....make X the subject

6x+15x-19x = 2+12

2x = 14..... divide both sides by 2

x = 7

this implies that, 19x + 2 where x is 7,

= 19(7) +2

=135°

therefore,<MNI = 135°

The angle MNI is 135 degree.

An angle is the figure formed when two rays cross at a common endpoint, according to the definition of angles.

The name of an interior angle of a triangle that is not adjacent to a given exterior angle of the triangle is remote Interior Angle.

Sum of two interior angles is equal one exterior angle.

Here:

(6 x) + (15 x-12) = (19 x+2)

6 x + 15 x - 19 x = 2 + 12

6 x - 4 x = 14

2 x = 14, x =7

Putting the value of x in (19 x + 2).

19 * 7 + 2 = 133 + 2 = 135.

Therefore, the value of 19 x + 2 is 135 degree.

x = 13°

Step-by-step explanation:

The left base angle of the triangle with x as the vertex is vertically opposite 85° and are congruent.

left base angle = 85°

the angle below the right base in the triangle is corresponding to 98° and are congruent.

right base angle = 180° - 98° = 82° ( adjacent angles on a straight line ) , then

x = 180° - (85 + 82)° = 180° - 167° = 13° ( sum of angles in a triangle )

The equation of the line that is parallel to the given line and passes through the point (2, 3) is,

[tex]x+2y=8[/tex]

The equation of the line is the way of representation of a line in the equation form.

The equitation of the lines represents the line by the set of points on which the line lies or passes through in the coordinate system.

Given information-

The points through which the line passes is (2, 3).

The points of the line shown in the image attached below is (-4, 0) and (4, -4).

The slope of the line shown in the image which passes through the point (-4, 0) and (4, -4) is,

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{-4-0}{4-(-4)}\\m=\dfrac{-4}{8}\\m=\dfrac{-1}{2}[/tex]

As the line which passes through the point (2, 3) is parallel to the line shown below. Hence, the slope of it must be equal to that line.

Therefore the equation of the line which passes through the point (2, 3) and has a slope of -1/2, is,

[tex](y-y_1)=m(x-x_1)\\(y-3)=-\dfrac{1}{2}(x-2)\\2(y-3)=-x+2\\2y-6=-x+2\\x+2y=8[/tex]

Thus the equation of the line that is parallel to the given line and passes through the point (2, 3) is,

[tex]x+2y=8[/tex]

Step-by-step explanation:

the equation for right cylinder surface area: 2πrh+2πr^2

Answer:

33π cm²

Step-by-step explanation:

To find surface area you add the area of every face.

Area of the 2 circle faces:

The formula for the area of circle is πr². If the diameter is 6 you divide that by 2 to get a radius of 3. The area of the circle is 9π. Sense the top and bottom are both circles you multiply the area by 2 to get 18π.

Area of side face:

To find the area of the side, it is the same as a rectangle (length [circumference] multiplied by height [2.5]). The forumla for the circumference of a circle is πd. The circumference is 6π so multiply that by the height of 2.5 to get the area of the side of 15π.

Total surface area:

Now add the 18π (area of 2 circle faces) with the 15π (area of side face) to get 33π cm² surface area.
