Which of the following is an obtuse triangle? A. Triangle BB. Triangle CC. Triangle A D. Triangle D

Answer:

b is -4

Step-by-step explanation:

we're given:

|2b + 2| = 6

substituting b for -4 :

|2(-4) + 2| = 6

|-8 + 2| = 6

|-6| = 6

any negative number between absolute value becomes positive.

Hence b is -4

The value of x if H is the midpoint of GJ is 31 units.

The midpoint is the middle point of a line segment.

It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints.

The midpoint is halfway between the two end points.

Therefore, H is the midpoint of GJ

Hence,

GJ = GH + HJ

GJ = 4x - 8

GH = 120

Therefore, GH and HJ are congruent because H is the midpoint of GJ

GH = HJ

Hence,

4x - 8 = 120 + 120

4x - 8 = 240

4x = 240 + 8

4x = 248

x = 248 / 4

x = 31

Answer:

$71.39

Step-by-step explanation:

So we can go ahead and add the extra money they paid (sales tax and tip).

15% + 6% = 21%

Then we can find 21% of 59 then that will be our extra money we're paying.

59 × 0.21 = 12.39

Then we add that amount to our 59 to get the total amount.

59 + 12.39 = 71.39

The equation of the line passing through (0, 0) and (2, –3) is y = - 3 / 2 x

The equation of a line can be described as follows:

y = mx + b

where

Therefore, using (0, 0)(2, -3)

m = y₂ - y₁ / x₂ - x₁

m = -3 - 0 / 2 - 0

m = - 3 / 2

Therefore, the y-intercept is 0.

Answer: 40

Step-by-step explanation:

The smallest number that all three numbers go into evenly is 40.

Therefore the LCM of 8, 11, and 20 is 40.

Answer:

440

Step-by-step explanation:

To find the Least common multiple (L.C.M) of 8, 11 and 20, it means that:

8 = 2,2,2

11 = 1, 11

20= 2,2,5

LCM of 8,11,20 = 2× 2 × 2 × 11 × 5

= 440

On solving the simultaneous equations 3x+2y=7 and 2x-3y=-4 , the value of x is 1 and the value of y is 2  .

In the question,

it is given that the simultaneous equations are

3x+2y=7   ....(i)

and

2x-3y=-4    ...(ii)

to solve these equations ,

we multiply equation(i) with 2 and

multiply equation(ii) with 3 .

So , the equations become

6x+4y=14 ...(iii)

and

6x-9y=-12 ....(iv)

we subtract equation (iv) from  (iii) ,

So,

(6x+4y)-(6x-9y)=14-(-12)

Solving further ,

6x+4y-6x+9y = 14+12

4y+9y = 26

13y = 26

y = 26/13

y = 2

Substituting the value of y as 2 in equation (iii) , we get

6x+4(2) = 14

6x + 8 = 14

6x = 14-8

6x = 6

x=6/6

x=1

hence x=1 and y=2 .

Therefore , On solving the simultaneous equations 3x+2y=7 and 2x-3y=-4 , the value of x is 1 and the value of y is 2  .

Answer:

∠1 = 103.9° ;  ∠2 = 27.8°

Step-by-step explanation:

Supplementary angles = 180°

So, Let the angles be 'x'

Then, x + x -27.8° = 180°

         2x - 27.8° = 180°

         2x = 180° + 27.8°

         2x = 207.8°

          x = 207.8°/2

          x = 103.9°

Therefore ∠1 = 103.9° ; ∠2 = 27.8°

the numerical value of x in fraction and decimal form are 11/2 and 5.5 respectively.

A midpoint is simply a point that divides a line segment into two equal halves.

Given the data in the question;

Since that T is the midpoint of segment SU, segment ST and segment TU are two equal halves of of segment SU.

Segment ST = Segment TU

a)Percentage increase is 23.07%.

b)Percentage increase is 28.5%.

Percentage is a relative value that represents hundredths of any quantity. Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified. By dividing the value by the entire value and multiplying the result by 100, one may determine the percentage. The percentage calculation formula is

([tex]\frac{value}{total value}[/tex])100%.

Given Data

Percentage increase = [tex]\frac{final value - starting value}{starting value}[/tex]× 100

a) Cost = $65

New cost = $70

Difference = 5

Equating,

Percentage increase = [tex]\frac{70-65}{65}[/tex] × 100

Percentage increase = [tex]\frac{15}{65}[/tex] × 100

Percentage increase = 23.07%

Percentage increase is 23.07%.

b) Cost = $45

New cost = $35

Equating,

Percentage increase = [tex]\frac{45-35}{35}[/tex] × 100

Percentage increase = [tex]\frac{10}{35}[/tex] × 100

Because triangle SRT and VUW are similar, all sides of triangle SRF are scaled up by an amount.

We calculate the scale factor : 9/5.4 = 5/3

-> The corresponding side of SR (UV)  is scaled down 5/3 times from the length of SR
-> UV = 6 : 5/3 = 3.6 (inches).

Answer:

x = 132°

Step-by-step explanation:

Sum of interior angles = (n - 2) x 180, where n is number of sides of the polygon.

Sum = (6 - 2) x 180 = 720°

sum = 160 +75 + 132 + 113 + 108 + x

sum = 588 + x

720 = 588 + x

x = 720 - 588

x = 132°

y = -5/2x-8 is the slope-intercept form for the lines that passes through the point (-6,7) and parallel to 5x+2y = 10.

Given that, the line 5x+2y = 10 passes through the point (-6,7) and is parallel to the given equation. Now, we have to write an equation in the slope-intercept form.

The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept( the y-coordinate of the point where the line intersects the y-axis).

The slope intercept form equation for a straight line with a slope, 'm', and 'b' as the y-intercept can be given as: y = mx + b.

where, m is the slope of the line and b is the y-intercept of the line.

Let's proceed to find the equation.

5x+2y = 10

2y = -5x+10

y = -5/2x+10/2

y = -5/2x+5

Now, comparing with y = mx+b (slope-intercept form)

m = -5/2 and b = 5

As the two lines are parallel with each other then the slope of other line will also be same as m = -5/2

Now, the line passing through the point (-6,7)

⇒ x₁ = -6 and y₁ = 7

y-y₁ = m(x-x₁) ..........(1)

putting values in equation (1), we get

y-7 = -5/2(x-(-6))

⇒ y-7 = -5/2(x+6)

⇒ y = -5/2x-15+7

⇒ y = -5/2x-8

This is the slope-intercept form for the lines that passes through the point (-6,7) and parallel to 5x+2y = 10.

Hence,  y = -5/2x-8 is the required answer.
