Answer:

s = 10

______________

To get from 4 to 8, you multiply by two. Because the triangles are congruent, you would do the same thing with 5 to S. 5 * 2 = 10. So S = 10

Step-by-step explanation:

As the triangles are similar,

The sides are proportional too.

So, we can see that

Side AB is proportional to XY

So, XY side is half of AB.

So, BC will be 5×2 = 10

So, 10 is the correct answer.

Select all that apply.Several pennies are tossed in the air. Twelve land heads up and fifteen land tails up. Which of the follow
OverLord2011 [107]
The information we've been given is:

12 heads
15 tails

From those, we find that there are 12 + 15 = 27 coins.

Let's examine these ratios as such:

- 12 heads to 27 coins -
There are indeed 12 heads and 27 coins, so this comparison agrees with our data.

- 15 tails to 12 heads - 
Again, nothing here contradicts with our data, so this would be correct as well

- 12 heads to 15 tails -
Simply a reversed version of the ratio above; still a completely valid way to compare the relative quantities of heads and tails

- 5 tails to 9 coins -
This one needs a little more examination. We observe that the ratio of tails to coins with our given data is 15 tails to 27 coins. This seems to go against our data, but we can simplify our ratio by dividing both the number of tails and the number of coins by 3, which indeed gives us the ratio 5 tails to 9 coins.

So, all of the given ratios are correct.

Eli Moran is an accountant at J & R Tax Prep, and during tax season he works overtime to meet the demand. He is paid $32 per
Sati [7]

Answer :

The value of number of hours overtime per week will he needed to achieve his earning goal = 5 hours

Step-by-step explanation:

Payment for first 40 hours = $ 32 per hour

Payment over 40 hours = $ 48 per hour

Eli’s goal is to earn = $ 1520 per week ------- (1)

Total payment for first 40 hours = 32 × 40 = $ 1280 ------ (2)

Suppose person worked x_{} hours in overtime, then

The total payment for x_{} hours = 48 × x_{}  = $ 48x_{} ------------ (3)

Total earnings of the person in a week ⇒ $ 1280 +  $ 48x_{} = $ 1520

⇒ 1280 + 48x_{} = 1520

⇒ 48x_{} = 1520 - 1280

⇒ 48x_{} = 240

⇒ x_{} = 5 hours

This is the value of number of hours overtime per week will he needed to achieve his earning goal.
