Answer:

1/12

Step-by-step explanation:

1) covert 1/2 to 3/6 to subtract 2/6 from it. this gets 2/6, which simplifies to 1/3

2) divide 1/3 by 4 which gets 1/12

Answer:

By using pythagoras theorem the problem can be solved;

(hypotenuse)^2=(pythagoras)^2+(base)^2

h^2=(20 mi)^2+(40 mi)^2

h^2=(400+1600) mi^2

h^2=2000 mi^2

h=√2000 mi^2

h=20√5 mi

Answer:

2/13

Explanation:

The bag has 6 red, 3 green, 4 blue.

Total marbles = 13

Probability of getting blue the first time would be 4/13 because 4 of the 13 total marbles are blue

Because you're not putting back the first marble, the total would go down to 12, so the probability of getting red the second time would be 6/12 or 1/2

The probability that the first marble is blue and the second marble is red = (4/13)(6/12) = 2/13

The distance of the jungle gym to swing is 120 feet.

We have given that the diagram

we have to find the distance between jungle gym and swings is,

suppose that x is shorter length then the hypotenuse is 2x and  [tex]x\sqrt{3}[/tex]

is the longer length

By using the Pythagoras formula we have

The length of CA is,

[tex]CA=60(2)=120[/tex]

Therefore the distance of the jungle gym to swing is 120 feet.

Answer:

C

Step-by-step explanation:

we should set the equations based on what we know using y=mx+b

in the first set, we have m=5 and the +b as 100. This gives y=5x+100

in the second, we  m=20  and the +b of 10. This gives y=20x+10

I belive C would match this. Hope this helps!

Answer:

D.   150°

Step-by-step explanation:

∠X and ∠W are supplementary

Let a = m∠X

Then 5a = m∠W

m∠X + m∠W = 180

a + 5a = 180

6a = 180

a = 30

m∠W = 5a = 5(30) = 150°

Answer and Step-by-step explanation:

Anything that is to the power of 0 is equal to 1. This is why 2 to the power of 0 is equal to 0.

0 is the only number such that for any number x, x + 0 = x. So, the reason that any number to the zero power is one is because any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1.

Answer:

The triangle will not be possible.

this is because two side lengths can't expand 14 units.

in order for the triangle to work, the sum of the two short side lengths must be greater than the longer side.

however, 6+6 does not equal 14 it equals 12 this means that the triangle is not possible
