Answer:

c)2:1..................

Answer:

C

Step-by-step explanation:

Find the distance of AB:

Distance formula: [tex]\sqrt{[(-8)-(-2)]^2+(9-1)^2}[/tex]

[tex]\sqrt{(-6)^2+(8)^2}=\sqrt{36+64}=\sqrt{100}=10 units[/tex]

Find the distance of BC:

Distance formula: [tex]\sqrt{[(-2)-1]^2+[1-(-3)]^2}[/tex]

[tex]\sqrt{(-3)^2+4^2}=\sqrt{9+16} =\sqrt{25} =5 units[/tex]

AB=10 units

BC=5 units

AB:BC = 10:5=2:1

Step-by-step explanation:

Answer:

x = 3.5

x = 0.1

x = 4

x = 20

(In order top to bottom)

Step-by-step explanation:

2(x) = 7

/2     /2

x = 3.5 (1st one)

60(x) = 6

/60    /60

x = 0.1 (2nd one)

12(x)=48

/12    /12

x = 4 (3rd one)

1/20(x)=1

x20    x20

x = 20 (4th one)

Equations:

1. 2 • x = 7

2. 60 • x = 6

3. 12 • x = 48

4. x • 1 over 20 = 1

Value of x (Answers):

1. 3.5

2. 0.1

3. 4

4. 20

Explanations:

For number 1;

7 ÷ 2 = 3.5

3.5 • 2 = 7

Therefore, 3.5 is your answer for number 1.

For number 2;

6 ÷ 60 = 0.1

0.1 • 60 = 6

Therefore, 0.1 is your answer for number 2.

For number 3;

48 ÷ 12 = 4

4 • 12 = 48

Therefore, 4 is your answer for number 3.

For number 4;

1 over 20 = 0.05

1 ÷ (1 over 20) = 20

20 • 1 over 20 = 1

Therefore, 20 is your answer for number 4.

Hope I made it clear for you, have a nice day!!! (I'm sorry that I am 4 months late.)

Answer:

[tex]t=4.4594[/tex]

Step-by-step explanation:

We can take the log 2 of both sides to get [tex]t=\log_2(22)[/tex].

We know that [tex]2^4<22<2^5[/tex], so [tex]4<t<5[/tex].

So, the solution is [tex]\boxed{t=4.4594}[/tex] because it's the only answer that works.

Step-by-step explanation:

the average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.

so,

(g(-3) - g(-9)) / (-3 - -9)

g(-3) = (-3)² + 10×-3 + 20 = 9 - 30 + 20 = -1

g(-9) = (-9)² + 10×-9 + 20 = 81 - 90 + 20 = 11

-3 - -9 = -3 + 9 = 6

(-1 - 11) / 6

-12/6 = -2

the average change rate in this interval is -2 (or fully -2/1).

Flat rate is the y- intercept b = 11.2

Charge per mile is the slope m = 3.1

The equation is:

Answer:

104

Step-by-step explanation:

∠JTS = ∠SRT  + ∠TSR   {exterior angles equals sum of opposite interiror angles}

27x - 4 = 18x + 2 + 30

27x  - 4 = 18x + 32

Add 4 to both sides

27x = 18x + 32 + 4

27x = 18x + 36

Subtract  18x from both sides

27x - 18x = 36

9x = 36

Divide  both sides by 9

x = 36/9

x = 4

∠JTS = 27x - 4

         = 27*4 - 4

         = 108 - 4

        = 104

Answer:

18

Step-by-step explanation:

You can cross multiply for this problem. So:

[tex]\frac{6}{10}=\frac{21}{K}\\6K=210\\K=35[/tex]

So K=35!

buuin ang mga sumosunod na hulwarang ritmo grade 4 mosic

If side JM = 30 and side LM = 8, the length of side KM is equal to 15.49 units.

In this exercise, we would assign the variable x to the length of side KM. Based on the information provided about triangle JKM and triangle KML, we can logically deduce the following parameters;

Side JL = [(30 + 8) × x]/2

Side JL = 38x/2

Side JL = 19x.

Since point M is the perpendicular bisector of both triangle JKM and triangle KML, the length of side KM can be calculated as follows;

19x = √[(30² + x²)(x² + 8²)]/2

38x = √[(30² + x²)(x² + 8²)]

By taking the square of both sides, we have:

38²x² = (900 + x²)(x² + 64)

38²x² = 900x² + 57,600 + x⁴ + 64x²

38²x² = 964x² + 57,600 + x⁴

(x² - 240)² = 0

x² = 240

x = √240

x = 15.49 units.

Answer:

  1 < x < 29

Step-by-step explanation:

The triangle inequality requires the sum of the two shortest sides exceed the longest side.

When x and 14 are the shortest:

  x + 14 > 15

  x > 1

When 14 and 15 are the shortest:

  14 +15 > x

  29 > x

Then the requirement for the length of x is ...

  1 < x < 29

Additional comment

The length of the third side of a triangle can be between the difference and sum of the two given sides.

Answer:

55°

Step-by-step explanation:

25 + 30 = 55°

180-55°=125° (x)

x adjacent with y

180-125=55

So y = 55°

Answer:

The choice C) 34°

Step-by-step explanation:

[tex]75 + (x + 42) + (x + 79) = 180 \\ 2x + 196 = 180 \\ 2x = 180 - 196 \\ 2x = - 16 \\ \\ x = \frac{ - 16}{2} \\ \\ x = - 8 \\ \\ x + 42 = > - 8 + 42 = 34[/tex]

Answer:

The answer is B because x = 4 so 12x4-3=45

Answer:

[tex]15x + 12x - 3 + 75 = 180 \\ 27x = 180 - 75 + 3 = 108 \\ x = 108 \div 27 = 4 \\ a = 12x - 3 = 12 \times 4 - 3 = 48 - 3 = 45[/tex]

Answer:

233.4 Centimeters

Step-by-step explanation:

48 x 10 = 480

48 x 4 = 192

480 + 192 = 672

139 x 10 = 1390

139 x 2 = 272

1390 + 272 = 1662

1662 + 672 = 2334

2334mm = 233.4cm

Answer:

[tex]s=-1[/tex]

Step-by-step explanation:

[tex]7=-10s-3[/tex]

[tex]-10s-3=7[/tex]

Add 3 to both sides:

[tex]-10s-3+3=7+3[/tex]

[tex]-10s=10[/tex]

Divide both sides by -10:

[tex]\frac{-10s}{-10}=\frac{10}{-10}[/tex]

[tex]s=-1[/tex]
