WILL GIVE BRAINLY Find the perimeter of the figure below, in meters.
(Note: diagram is NOT to scale)

Answer:

Step-by-step explanation:

∠1 + ∠2 + ∠3 + a = 360   {Sum of all angles of quadrilateral}

76 + 27 + 17 + a = 360

          120 + a = 360

                    a = 360 -120

a = 240°

a + ∠4 = 360    

240 + ∠4 = 360

∠4 = 360 - 240

∠4 = 120°

Scalene:  F, B

Equilateral:  H, D, C

Isosceles:  G, E, A,

Hope this helped!

Answer:

A = 8

B = 6

C = 4

D = 7

Top = 29

Side = 20

Step-by-step explanation:

To get A on the bottom side row you divide 32 by 4 and get 8.

To get D, on the first side row, subtract A, 8, now it's 21, 21 divided by 3 is 7.

To get B, on the first top row, subtract A and D, now divide by 2 and you get 6.

To get C, on the third side row, subtract B and divide by 2 and you get 4.

Answer:

  n = 24

Step-by-step explanation:

Multiply the given equation by the product of denominators. Then subtract 6n and go from there.

  [tex]\dfrac{6}{n-6}=\dfrac{8}{n}\\\\6n=8(n-6)\qquad\text{rid of fractions}\\\\0=2n-48\qquad\text{subtract 6n, simplify}\\\\0=n-24\qquad\text{divide by 2}\\\\\boxed{24=n}\qquad\text{add 24}[/tex]

Alternate solution

Any proportion can be written 4 ways. If we write this one "sideways," we have ...

  6/8 = (n -6)/n

  1 -1/4 = 1 -6/n . . . . . expand in parallel fashion

  6/n = 1/4 . . . . . . . . subtract 1, multiply by -1

  n = 24 . . . . . . . . . multiply by 4n

__

Another alternate solution (can be done mentally)

The above "sideways" proportion can be reduced to ...

  3/4 = (n -6)/n

The difference between values on the left is 1 unit. On the right, the difference between values is 6. (The numerator is 6 less than the denominator.) The denominator on the left (4) is 4 times the difference, so the denominator on the right (n) will likewise be 4 times the difference: n = 4·6 = 24. Check: 3/4 = 18/24.

Answer:

x= -1 y=3

Step-by-step explanation:

Answer:

x = -1

y = 3

Step-by-step explanation:

2x +y =1 3x -y= -6

Add the two equations together to eliminate y

2x +y =1

3x -y= -6

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

5x = -5

Divide by 5

5x/5 = -5/5

x = -1

2x+y = 1

2(-1) +y = 1

-2 +y =1

Add 2 to each side

y = 1+2

y =3

Answer:

Basic wage rate = $9.375 per hour

Step-by-step explanation:

Given :

Fortnight wage = $750

Basic week, hours worked per week = 40 hours

Weekly basic wage rate :

Fortnight = 2 weeks

Hence, weekly wage = fortnight wage / 2 = 750 /2 = $375

Weekly basic wage rate = $375 / Number of hours worked per week = $375 / 40 = $9.375 per hour

From the graph, the given points are (2,-1) and (4,0). Use the distance between two points formula:

[tex] \large \boxed{ \sqrt{ {(x_2 - x_1)}^{2} + {(y_2 - y_1)}^{2} } }[/tex]

Substitute these points in the formula.

[tex] \large{ \sqrt{ {(2 - 4)}^{2} + {( - 1 - 0)}^{2} } } \\ \large{ \sqrt{ {( - 2)}^{2} + {( - 1)}^{2} } } \\ \large{ \sqrt{4 + 1} \longrightarrow \sqrt{5} }[/tex]

Hence, the distance is √5

Answer

Answer:

x ≤ 5.5

Step-by-step explanation:

Amount with Tyler = $600

Cost of new bicycle = $233.09

Cost of 3 bicycle reflectors = $16.38 * 3

= $49.14

Cost of bike gloves = $29.13

Cost of biking outfit = $52.48

Number of biking outfit = x

233.09 + 49.14 + 29.13 + 52.48x ≤ 600

311.36 + 52.48x ≤ 600

52.48x ≤ 600 - 311.36

52.48x ≤ 288.64

x ≤ 288.64/52.48

x ≤ 5.5

Number of biking outfit = x

x ≤ 5.5

Answer:

-x²+8x-15

Step-by-step explanation:

There are two solutions: 3 and 5

First, let's write the equation in this form (pay attention, the parabola here is going up so it won't be like your graph):

(x-3)(x-5)

For resolve our problem, let's re-write it with a minus before:

-(x-3)(x-5)

You can also expand it and the result will be like this:

-x²+8x-15

Answer:

x-5

x-2

Step-by-step explanation:

Questions 1:

√(x²-10x+25)

x²-10x+25= (x-5)²

√(x-5)²= x-5

question 2:

x²-4x+4= (x-2)²

√(x-2)²= x-2

10m by 20m

12 m by 18 m

14m by 16m

Step-by-step explanation:

The perimeter of a rectangle is

P = 2(l+w)

60 = 2(l+w)

Divide each side by 2

30 = l+w

Let l = 10

Then w = 30 - 10 = 20

Let l = 12  then w = 30 - 12 = 18

Let l = 14  then w = 30 -14 = 16

Answer:

25

Step-by-step explanation:

The pattern is + 1, + 3, + 6,...   i.e. + 1, + (1 + 2), + (1 + 2 + 3),...

.'. Missing number = 15 + (1 + 2 + 3 + 4) = 25.

Answer: 25!

Step-by-step explanation:

5, 6, 9, 15, ?, 40

5 + 1 = 6

6 + 1 + 2 = 6 + 3 = 9

9 + 1 + 2 + 3 = 9 + 6 = 15

15 + 1 + 2 + 3 + 4 = 15 + 10 = 25

25 + 1 + 2 + 3 + 4 + 5 = 25 + 15 = 40

Answer:

The number is  2

Step-by-step explanation:

Twice a number (z) = 2*z = 2z

Twice a number (z) added to 21  = 2z + 21

9 times the number added to 7 = 9z + 7

9z + 7 = 2z + 21

Subtract 2z form both sides

9z - 2z + 7 = 21

       7z + 7 = 21

Subtract 7 from both sides

7z = 21 - 7

 7z = 14

Divide both sides by 7

z = 14/7

z = 2

Answer:

[tex]H=20(0.8)^{n}[/tex]

Step-by-step explanation:

So, lets just go over this step by step and make sense of it.

20 clearly must be what we start with, and as you see in your answers, all of them have that as the number you multiply the parethese by.

Its what next that we dont know about.

We know that the ball rebounds 80% of its previous height.

It for sure cannot be a or d because a would mean that it would only rebound 20% of its height, and d would mean that it rebound 180% of its height.

Its now between b and c.

Lets just think about it.

Pull out your calculator or pull it up on your electronic. Multiply 10 by 0.9. This will get you 9. Multiply 9 again by 0.9, and youll get 8.1.

What did we actually do there? We did 10*0.9^2

Pull out your calculator again and try 10* 0.9^2. Youll see that 0.9 squared is 0.81. This times 10 is 8.1, and that is exactly what you got before.

Understanding this, it is clear that we must use an exponent to fidn future values.

In answer b, it shows that you can just multiply by n.

In answer c however, it uses n as an exponent, which is the correct thing to do.

So c is your answer.

The actual formula for this is: [tex]first_.term(change)^t^e^r^m ^[/tex]

The first term in this case is the first height, which is 20. The change is a rebound of 80%(0.8).

The term is just n, but in most problems n is time.

Translation 5 units up is correct

Answer:

Perimeter = AB + AC + BC = 26.55 units

Step-by-step explanation:

The perimeter of a triangle is the sum of lengths of all sides.

Here we have a right triangle, right-angled at C

angle B = 46°

AB = 11

We continue to calculate

AC = (11)sin(46°) = 7.91

BC = (11)cos(46°) = 7.64

Perimeter = AB + AC + BC = 26.55 units

Answer:

Points that lie along the same line are said to be "collinear" and collinear points must have the same slope between any pair of points.

~ƒöᏝϗʆѻʁᶥąռ¹₃

[tex]\huge\boxed{\underline{\bf \: Answer}}[/tex]

The answer will be option 1 :-

Well, for a straight line the points formed are known as collinear points & the points given ->( -1, –4), (0, 1), (1, 4) are not collinear as they are not formed in the same line of the graph. Also, graphs have straight lines. From this we can see that none of the other options work. Hence, option 1 is the correct answer (✓).

Answer:

An equation with -8 as the slope.

Step-by-step explanation:

I can't see your choices but you need to look for an equation in which the slope is -8. A line with an opposite reciprocal slope is needed in order to be perpendicular to the line y = 1/8x + 3. The opposite reciprocal of 1/8 is -8.
