Answer:

1/2

Step-by-step explanation:

The denominator is the number of sides, in this case 6.

The numerator is how many occurrences within that number is desired outcome. In this case they want odd numbers, so in a six sided dice there are 3 odd numbers (1, 3, 5). So your probability is 3/6 or 1/2.

Step-by-step explanation:

A six sided dice contains even numbers on three sides and odd numbers on remaining three sides.

Therefore,

Probability of rolling an odd number

$= \frac{3}{6} \\ \\ = \frac{1}{2}$

A ladder is leaning against a wall. The top of the ladder is 9 feet (ft) above the ground. If the bottom of the ladder is moved

Komok [63]

Step 1

First situation

when a ladder is leaning against a wall

Let

x-------> the distance of the bottom of the ladder from the wall

L-------> the length of the ladder

Find the length of the ladder

Applying the Pythagorean Theorem

$L^{2} =x^{2}+ 9^{2}$ ------> equation $1$

Step 2

Second situation

when the ladder will be lying flat on the ground

Find the length of the ladder

In this situation the length of the ladder is equal to

$L=x+3$

square both sides

$L^{2}=(x+3)^{2}$ ------> equation $2$

Step 3

equate equation $1$ and equation $2$

$x^{2}+ 9^{2}=(x+3)^{2}\\x^{2}+81=x^{2} +6x+9\\ 6x=81-9\\6x=72\\x=12\ ft$

therefore

the answer is

the length of the ladder is $12\ ft$

Find the unknown number 5/12+()=1/2

xenn [34]

Hello from MrBillDoesMath!

Answer: 1/12

Discussion:

We solve 5/12 + x = 1/2 for x. Begin by subtracting 5/12 from each side

5/12 - 5/12 + x = 1/2 - 5/12

0 +x = 6/12 - 5/12 (as 1/2 = 6/12)

So x = 1/12

one fruit punch had 40% fruit juice and another is 90% fruit juice. how much of the 40% punch should be mixed with 30 gallons of

sashaice [31]

A = fruit juice 40%

B= 90% juice

then

30 gallons + A = 55• C/100

30 gallons + N • (40/100) = (30 + N)• (55/100)

Now solve this equation, for N

3000 + 40N = (30+N) •55

then

3000 - 1650 = 55N - 40 N = 15N

1350 = 15 N

then

N= 1350/15 = 90

Then answer is

Should be mixed 90 gallons of 40% fruit punch
