okay so its going up in 3

starting from 8

8,11,14,17,20,23

Answer:

Step-by-step explanation:

1). JL = 36

   Reason : Since, PN is the segment joining midpoints of sides JK and LK,

   Therefore, JL = 2(PN)

   JL = 2(36)

   JL = 72

   False.

2). ML = 36

    Reason: Since, ML = [tex]\frac{1}{2}(JL)[/tex]

    ML = [tex]\frac{1}{2}(72)[/tex]

          = 36

    True.

3). MP = 48.5

    Reason : By the same property, MP = [tex]\frac{1}{2}(LK)[/tex]

    MP = [tex]\frac{97}{2}[/tex]

    MP = 48.5

    True.

4). ∠JLK = 102°

    Reason: Segment joining midpoints of two sides of a triangle is parallel and measures half of the third side of the triangle.

     Since, PM║LK and JL is a transversal line,

     ∠JMP ≅ ∠JLK [Corresponding angles]

     m∠JLK = 102°

     True.

5). ∠PNK = 102°

    Reason : Since, PN║JL and LK is a transversal line,

    ∠JLK ≅ ∠PNK [Corresponding angles]

    ∠PNK = 102°

     True.

6). MP║PK

    Reason : MP and PK are intersecting each other at P.

    Therefore, they can not be parallel.

     False.

Answer:

E is the answer

Step-by-step explanation:

This is a cyclic quadralterial so 21x-2 and 38x+5 is supplementary since they are opposite angles.

[tex]21x - 2 + 38x + 5 = 180[/tex]

[tex]59x + 3 = 180[/tex]

[tex]59x = 177[/tex]

[tex]x = 3[/tex]

Substitute 3 into angle A

[tex]38(3) + 5 = 119[/tex]

Since HA, is the intercepted arc of Angle G Angle G is twice the size of Arc HA,

Angle G=238

Sol➜

We have, tan(A + B) = √3

⇒ tan(A + B) = tan60°

∴ A + B = 60° -----[i]

Again, tan(A - B) = 1/√3

⇒ tan(A - B) = tan30°

∴ A - B = 30° -----[ii]

Now, Adding [i] and [ii], we get

A + B + A - B = 60° + 30°

2A = 90° ⇒ A = 45°

Putting the value of A in [i], we have

45° + B = 60°

∴ B = 60° - 45° = 15°

Hence, A = 45° and B = 15°.

Answer:

[tex] \displaystyle A = {45}^{ \circ} \\ B = {15}^{ \circ}[/tex]

Step-by-step explanation:

we are given two equation and condition

[tex]\displaystyle \begin{cases}\tan(A+B)=\sqrt{3} \\ \tan(A - B) = \dfrac{1}{ \sqrt{3} } \end{cases}( {0}^{ \circ} < A+B < {90}^{ \circ} ) \: \text{and} \: A > B[/tex]

let's work with first equation

recall unit circle so A and B should be in Q:I

[tex] \displaystyle \: A+B = \arctan( \sqrt{3} )[/tex]

[tex] \displaystyle \: A+B = {60}^{ \circ} \cdots \: \text{I}[/tex]

let's work with second equation:

[tex] \displaystyle \: \tan(A - B) = \frac{1}{ \sqrt{3} } [/tex]

[tex] \displaystyle \: A - B = \arctan(\frac{1}{ \sqrt{3} } )[/tex]

[tex] \displaystyle \: A - B = {30}^{ \circ} \cdots \: \text{II}[/tex]

now let's use elimination method to figure out A and B

to do so combine equation I and II

[tex] \displaystyle \underline{\begin{array}{c c c}A+B = {60}^{ \circ} \\ A - B = {30}^{ \circ} \end{array}} \\ 2A = {90}^{ \circ} [/tex]

divide both sides by 2:

[tex] \displaystyle \: \frac{2 A}{2} = \frac{ {90}^{ \circ} }{2} \\ A = {45}^{ \circ} [/tex]

substitute the value of A to the second equation:

[tex] \displaystyle \: {45}^{ \circ} - B = {30}^{ \circ} [/tex]

cancel 60° from both sides:

[tex] \displaystyle \: - B = { - 15}^{ \circ} [/tex]

divide both sides by -1

[tex] \displaystyle \: B = {15 }^{ \circ} [/tex]

hence,

[tex] \displaystyle \: A = {45}^{ \circ} \\ B = {15}^{ \circ} [/tex]

Step-by-step explanation:

The rectangular prism has a volume equal to V=xyz. V=(1/3)3(5/3)=5/3 in^3. The cube has a volume equal to V=s^3. The volume of the cube is equal to the prism when

[tex]s^3=(1/3)(3)(5/3)\\ \\ s^3=5/3\\ \\ s=\sqrt[3]{\frac{5}{3}}in\\ \\ s\approx 1.19in[/tex]

Answer:

A. 9.8 h

Step-by-step explanation:

1. Use the formula d = rt. Find t for r = 46.6 m/h and d = 456.68 m. Show your work.

2. Express 0.578 in words

1. d = rt

456.68 = 46.6 times t

divide both sides by 46.6 to get 9.8  

So the time is 9.8

2. 0.578 is five hundred seventy-eight thousandths

Hope this helps

For the first problem all you have to do is plug in r and d in the equation and solve for t.  So here is how we do that:

d=rt

546.68=46.6t

11.73=t

All we did there was divide both sides to isolate t (get t by itself).

For the second one you just need to know the places after the decimal point.  The first spot is the tenths, the second is the hundredths, and the third is the thousands.  So you would read 0.578 as:

Five-hundred and seventy-eight thousandths.

Substituting:

456.68 = 46.6t, so, dividing ach side by 46.6:

t = 456.68/46.6, so

t = 9.8

2. nought point five seven eight.

Answer:

Lesser r = - 7 - √11  or -10.32 to nearest hundredth.

greater r = - 7 + √11  or -3.68 to nearest hundredth.

Step-by-step explanation:

(x + 7)^2 – 11 = 0

(x + 7)^2 = 11

x + 7 = ±√11.

Yes, GCF stands for (greatest common factor)

so to find it do this:

   List the prime factors of each number.

   Circle every common prime factor — that is, every prime factor that's a factor of every number in the set.

Answer:

4 Hours

Step-by-step explanation:

The original boating fee is $60 then you add $20 per hour so 20 x 4 = 80

80+60=140 $140

Answer: 140=60+20x. He kept the boat for 4 hours

Step-by-step explanation:

x=hours

y=final cost and the final cost is $140

to find x you would use the equation: 140=60+20x

you would first subtract 60 from both sides and you would get:

80=20x

Now you would divide 20 from both sides

So x is 4

0

Because if you drank the jukebox and threw it away you wouldn't have anymore

Answer:

23 x-29y=98.......(1)

29 x-23y=110.......(2)

adding (1) and (2)we get

52 x-52y=208

52(x+y)=208

x-y=4...(3)[we get four by dividing 208 with 52]

subtract (2) from (1) we get

-6 x-6y=-12

x-y=2.....(4)

adding (3) and (4) we get

2x=6

therefore x=3

now from (4) we get

x-y=2 [we substitute xfor 3]

3-y=2

y=2-3

y=-1( that is the answer for your first question)

Step-by-step explanation:

99x+101y=499.....(1)

101x+99y=501.....(2)

add (1) and (2)

(99+101)x+(101+99)=(499+501)

200x+200y=1000

200(x+ y)=1000

x+y=5.....(3)

subtract (2)from(1) we get

2x-2y=2

2(x-y)=2

x+y=1.......(4)

x+y=5

x-y=1(add them together)

2x=6

x=3

substitute x equal to 3 in equation (3)

x+y=5

3+y=5

y=2

y equal to 2 and x equal to 3
