Answer:

7 hrs

Step-by-step explanation:

$187 for 11 hrs

$119 for x hrs

write a proportion.

187/11 = 119/x since Reuben is making money at the same rate.

solve for x:

187x = 1309

x=7

Answer:

7 hours

Step-by-step explanation:

Reuben works for 11 hours to earn $187

This means, his earnings rate is $187 per 11 hours of work

In 1 hour he would earn = 187/ 11 = $17

Therefore, he earns $17 in 1 hour

To find out how many hours he has to work to make $119, we multiply this by the rate.

He will earn $119 in = $119 x (1 hour/ $17) = 7 hours

Reuben has to work 7 hours to make $119

In five-card poker, a straight consists of five cards with adjacent denominations (e.g., 9 of clubs, 10 of hearts, jack of heart
GREYUIT [131]

Answer:

0.000394

Step-by-step explanation:

First we will find the probability of selecting five cards out of pack of cards

Probability of selecting five cards is equal to

^{52}C_5

On expanding we get

\frac{52!}{47! * 5!} \\

\frac{52 * 51 * 50 * 49 * 48 * 47!}{47 ! * 5*4*3*2*1} \\= 2598960

straight high card 9 means five cards with values lesser than 9 but adjacent to it are

9, 8, 7, 6, 5

there are four card for each number

Hence, probability of choosing five cards is equal to

4*4*4*4*4\\= 1024

Probability of getting a straight with high card 9 is equal to

\frac{1024}{2598960}

Write an equation for the line that is parallel to the given line and passes through the given point Y= 1/2 x -8 (-6 ,-17)
mylen [45]
Parallel to : y = 1/2x - 8

Passes through (-6, -17)

Our given slope is 1/2.

Plug the given coordinates into point-slope form.

y - y₁ = m(x - x₁)

y - (-17) = 1/2(x - (-6))

Simplify.

y + 17 = 1/2(x + 6)  ← Your answer.

However, sometimes teachers want this simplified even further.

So, simplify this.

y + 17 = 1/2x + 3

Subtract 17 from both sides.

y = 1/2x + 3 - 17

Simplify.

y = 1/2x - 14 ← Slope-intercept form.

Standard form → -1/2x + y = -14

Need help pls geometry question
Furkat [3]

Answer:

55.94°

Step-by-step explanation:

Reference angle = x

Hyp = 25

Adjacent = 14

Apply CAH:

Cos(x) = \frac{Adj}{Hyp}

Cos(x) = \frac{14}{25}

x = Cos^{-1}(\frac{14}{25})

x = 55.9442023° ≈ 55.94° (to 2 d.p)
