<h3>Answer:  D) 10</h3>

===========================================================

Explanation:

y = 5 because the long leg is exactly sqrt(3) times that of the short leg.

The short leg is always opposite the 30 degree angle.

The hypotenuse x is twice that of y, so x = 2y = 2*5 = 10

All of these rules only apply to 30-60-90 triangles. You can use trig ratios as an alternative route.

Minchanka [31]

Answer:

There are 26 alternative schools in the country

Step-by-step explanation:

Let

x------> the number of charter schools

y----->  the number of alternative schools

we know that

x=48

x=2y-4 -----> equation A

substitute the value of x in the equation A and solve for y

48=2y-4

2y=48+4

2y=52

y=26

A small company's net income for the first six months of the year was $76,500 and for the last six months it was $100,000 what i
Talja [164]
<span>The<u> correct answer</u> is:

153/200.

Explanation<span>:

The amount for the first 6 months is 76500 and the amount for the last 6 months is 100000. This makes the ratio 76500/100000.

Both of these end with two 0's; this means they are both divisible by 100. 76500/100 = 765 and 100000/100 = 1000; this makes the ratio 765/1000.

Since these end with a 5 or a 0, they are divisible by 5; 765/5 = 153 and 1000/5 = 200; this makes the ratio 153/200.

153 is only divisible by 3 or 9; 153/3 = 51 and 153/9 = 17. None of these will divide evenly into 200, so we stop at 153/200.</span></span>
