what is the answer?????​

Answer:

C

Step-by-step explanation:

A rational number can be expressed in the form

[tex]\frac{a}{b}[/tex] ← a, b are integers

A

[tex]\sqrt{81}[/tex] = 9 = [tex]\frac{9}{1}[/tex] ← rational

B

9.5 = 9 [tex]\frac{1}{2}[/tex] = [tex]\frac{19}{2}[/tex] ← rational

C

π is irrational then 5π is irrational

D

[tex]\sqrt{3^2}[/tex] = [tex]\sqrt{9}[/tex] = 3 = [tex]\frac{3}{1}[/tex] ← rational

Answer:

c

Step-by-step explanation:

A rational number can be expressed in the form

← a, b are integers

Answer:

Fastest train: 65 mph

slowest: 55 mph

Step-by-step explanation:

Divide 480 by 4

=120

To find average speed divide 120 by 2

=60

call the speed of the slowest train y.

y+(y+10)=120

2y=110

y=110/2=55

y+10=65

Answer:

[tex]\frac{85}{800}[/tex] or [tex]\frac{17}{160}[/tex] simplified

Step-by-step explanation:

In order to find the probability of this sequence of events happening we first need to find the probability of each event happening seperately and then multiply them together.

If there are 40 slip-joint pliers and only 5 are 6-inch then the probability of picking a 6-inch plier is 5/40. If there are a total of 20 rubber malets and only 3 are small then the probability of picking a non-small rubber mallet would be 17/20... Now we simply multiply these two probabilities together...

[tex]\frac{5 *17}{40 * 20}[/tex] = [tex]\frac{85}{800}[/tex] or [tex]\frac{17}{160}[/tex] simplified

Step-by-step explanation:

Answer:

earthquake

Step-by-step explanation:

There is no sign of water on the house materials nor on the pavement so flood and tsunami are out. If a land slide came through, multiply houses would have been seen with this in the back ground which there aren't. So the best possibly choose in my opinion is earthquake.

Answer:

x = 5

Step-by-step explanation:

A quadratic equation:

f(x) = y = a*x^2 + b*x + c

Has a vertex in a point:

(h, k) such that:

h = -b/2a

and:

k = f(-b/2a)

And the axis of symmetry (this is the line that cuts the graph in two halves) is:

x = h.

In this case, the vertex is (5, -6)

Then the axis of symmetry is:

x = 5.

Answer:

[tex]A=256.67ft^2[/tex]

Step-by-step explanation:

From the question we are told that:

Fan oscillates [tex]\theta=250[/tex]

Distance [tex]d=>Raduis\ r=4 feet[/tex]

Since

 [tex]250\textdegree =180\textdegree +70\textdegree[/tex]

Generally the equation for the area A is mathematically given by

 [tex]Area=Area\ of\ semi\ circle\ + area\ of\ 70\textdegree sector[/tex]

 [tex]A=A_{sm}+A_{70\textdegree}[/tex]

Where

 [tex]A_{sm}=\frac{1}{2} \pi r^2[/tex]

 [tex]A_{sm}=\frac{1}{2} 3.14 4^2[/tex]

 [tex]A_{sm}=25.12ft^2[/tex]

 [tex]A_{70\textdegree}=\frac{1}{2}r^2 \frac{70\textdegree}{360\textdegree}[/tex]

 [tex]A_{70\textdegree}=\frac{1}{2}*4^2* \frac{70\textdegree}{360\textdegree}[/tex]

 [tex]A_{70\textdegree}=1.55ft^2[/tex]

Therefore the area A is given as

 [tex]A=A_{sm}+A_{70\textdegree}[/tex]

 [tex]A=25.12ft^2+1.55ft^2[/tex]

 [tex]A=256.67ft^2[/tex]

Answer:

x = 12

Step-by-step explanation:

Both angles have the same measurement, therefor you can set your formula up as

9x + 1 = 11x-23

9x + 1 + 23 = 11x

24 = 2x

24/2 = x

12 = x

Answer:

C. 80 ft

Step-by-step explanation:

Volume=width ×height ×length

5×2×8 = 80

Answer:

Step-by-step explanation:

Isolate by the x from one side of the equation.

First, you have to subtract by 3x from both sides.

[tex]\sf{4x-3x=3x+5-3x}[/tex]

Solve.

x=5

[tex]\large\boxed{x=5}[/tex]

Therefore, the solution is x=5.

Answer:

D =  ( d * 5500 ) / W

Step-by-step explanation:

Diameter of rope " d "  supports "w" weight

i.e.  d = W

d ( inches ) = W ( pounds )

   ? ( inches ) = 5500 pounds

The Unknown diameter  D ( ? ) = d * 5500 / W

Answer:

15

Step-by-step explanation:

i dont know if your looking for the area but i can help you out on that, and im sooper sorry if this is the wrong answer! Plz forgive me if so!

d,a is 3 and from d to c is 5, 3x5=15, thats the area of the square!!

If you were looking for a different answer plz forgive me you didnt exactly tell us what you were looking for so i kinda just guessed it was area of the square real sorry if this is wrong!!

Answer:

XY = 10

Step-by-step explanation:

By the definition of midpoint, XM would be equal to MY, so we can set both equations equal to each other;

XM = MY

8 - t = 5t - 10

=> Now add "t" to both sides of "="

8 = 6t - 10

=> add 10 from each side;

18 = 6t

=> Finally divide 6 on each side

3 = t

Now that we have the value for t, we can substitute 3 in place of "t" in any of the equation above and solve, when we have the answer, multiply it by 2 to get the value for XY.

=> 8 - 3

=> 5

=> XY = 5 * 2

=> XY = 10

Hope this helps!
