Answer:

$144

Step-by-step explanation:

To find the total with the 20% tip, multiply 120 by 1.2

120(1.2)

= 144

So, the total is $144

Answer:

  y +2 = -1/2(x -7)

Step-by-step explanation:

The line PQ has a rise of 6 units for a run of 3 units, so its slope is ...

  m = rise/run = 6/3 = 2

A line perpendicular to PQ will have a slope that is the opposite reciprocal of that, so ...

  -1/m = -1/2

We have the slope of the desired line, and a point it needs to pass through, so we can use the point-slope form of the equation of a line.

  y -k = m(x -h) . . . . . . line with slope m through point (h, k)

An equation for the desired line is ...

  y +2 = -1/2(x -7)

__

This can be rearranged to other forms.

  y = -1/2x +3/2 . . . . . slope-intercept form

  x +2y = 3 . . . . . . . . . standard form

Answer:

A. No

Step-by-step explanation:

the point (2, 9) means x = 2 and y = 9.

plug this into the equation:

9 = -5 * 2 + 1

9 = -10 + 1

9 = -9

Answer:

Since the triangles are congruent, AB=ED so AB=14

Angles F is congruent to angle C so F=39 degrees

Step-by-step explanation:

Answer:

Step-by-step explanation:

AS the triangles are congruent corresponding sides and angles are congruent.

So AB = DE = 14.

m < F = m < C =  39 degrees.

Step-by-step explanation:

|-80|=80

|x| -≥ this symbol is named as mod

we use this to find the absolute value...

it can be explained easily as meaning like rounding off

I'm that even the number given inside in negative we should write the answer only in positive

negative number can never be the answer of absolute value

Answer:

6,120

Step-by-step explanation:

The computation of the total fund is shown below

Given that

The ratio between Sean, barry and Cian is 4:3:2

And, Cian got 1224

Now the total of ratio is

= 4 + 3 + 2

= 10

And, cian ratio is 2

So, the total fund is

= 1224 × 10 ÷ 2

= 6,120

Answer:

option A is correct answer of this qn

The word which best describes XV is Angle Bisector.

A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.

Sum of the interior angles of a triangle is 180 degrees.

Given is a triangle XYZ.

Here a line segment is drawn from the vertex X to the opposite side YZ.

Median is the line segment joining the vertex of a triangle to the mid point of the opposite side.

Here, it is not given that, YV = ZV, so it is not median.

Altitude is the perpendicular line joining the vertex to the opposite side.

Here, it is not given the line is perpendicular. so it is not altitude.

Perpendicular bisector is a line that bisects the opposite line in to right angles. It is also not given.

Angle bisector is a line which divide the angle from which the line is drawn. here it is given that both angles equal to 40°.

So the line is angle bisector.

Hence the correct option is Angel Bisector.

Item a:

x = 7, hence, the solution is:

[tex]y > 2 + 9(7)[/tex]

[tex]y > 67[/tex]

67 > 65, hence it is a solution.

Item b:

x = 8, hence, the solution is:

Answer:

-15 5/6

Step-by-step explanation:

Combine the given terms (through addition and subtraction).

14 7/8  -  15  -  5/6  -  14 7/8

Identify the LCD:  It is 24

Therefore we have:

14 21/24 - 15 - 20/24 - 14 21/24

Combining the whole numbers, we get

14 - 15 - 14, or -15

and combining the fractions, we get

21 - 20 - 21

----------------- = -20/24

       24

and so we have -15 - 20/24, or -15 - 5/6, or -15 5/6

Answer:

if it is a trapzium then area will 14.5 ft sq

Answer:

area = 14.5 ft^2

Step-by-step explanation:

area = (6.5 x 2) + (0.5)(1.5)(2)   (the base of the triangular shape is 8 - 6.5 = 1.5)

area = 13 + 1.5 = 14.5 ft^2
