Sloan [31]
The answer is C

The reason: There are two width and two length sides. So, therefore, if you want the fencing to equal 40 feet around the perimeter, 8 · 2 + L · 2 has to = 40.
You would factor 2 out, and you get 2(8 + L) = 40.

The half-life of a radioactive kind of ruthenium is 40 days. If you start with 240 grams of it,
Vlad [161]

Answer: 30g

Step-by-step explanation:

In this question (t½) of isotope is 40 days, which means that after 40 days half of the sample would have decayed and half would be left as it is.

After 40 days ( first half life) 240 /2 = 120 g decays and 120 g remains left.

After another 40 days ( two half lives or 80 days) 120 /2 = 60 g decays and 60 g remains left .

after three half lives or 120 days, 60/2 = 30g decay and 30 g of the isotope will be left.

Which ordered pair is the best estimate for the solution of the system of equations? y=−1/2x+4y=1/2x−3
tamaranim1 [39]
If we add the 2 equations the terms in x dssappear and we get

2y = 1
so y = 1/2 

Substitute in first equtaion:-

1/2 = - 1/2 x + 4
-1/2 x = 1/2 - 4 = - 7/2
x = -7/2 * -2 =  14/2 = 7  

answer is (7, 1/2)
