Answers
Answer:
1. x = 58
2. x = 44
Step-by-step explanation:
#1:
2x + 5 + x + 2x + 7 + x = 360
Step 1: Combine 2x, x, 2x, and x to get 6x.
6x + 5 + 7 = 360
Step 2: Add 5 & 7 to get 12.
6x + 12 = 360
Step 3: Subtract 12 from both sides
6x = 360 - 12
6x = 348
Step 4: Divide both sides by 6.
x = 348/6
x = 58
#2:
3x + 2 + 2x + 2x + 1 + x + 5 = 360
Step 1: Combine like terms.
8x + 2 + 1 + 5 = 360
8x + 8 = 360
Step 2: Subtract 8 from both sides.
8x = 360 - 8
8x = 352
Step 3: Divide both sides by 8.
x = 352/8
x = 44

A 256- gallon barrel of radioactive Urikium is spilled at a factory. The entire area is evacuated. Experts say that the area can be deemed safe after only 2 gallons remain. Unfortunately, it is to toxic for any clean-up efforts, so residents will just have to wait for the Urikium to evaporate. Fortunately, Urikium has a half-life of only three hours. That means that half of the Urikium will evaporate every three hours
Answers
Answer:
21 hours
Step-by-step explanation:
Since 2^8 = 256, that means it will take 7 half-lives to become two gallons
7 half-lives * 3 hours = 21 hours
256, 128, 64, 32, 16, 8, 4, 2
Answer:
Experts say that the area can be deemed safe after only 2 gallons remain. Unfortunately, it is too toxic for any clean-up efforts. She residents will
Step-by-step explanation:
To solve half-life problems, you use the equations:
f(t) = T0 (1/2)^(t/t1/2). where T0 is the initial mass and T1/2 is the half-life.
So we get f(20)= 5 = T0•(1/2) ^ 20/11
T0 = 17.63 mg
For the second part of the question, we plug 0.5 mg into the equation:
0.5 = 17.63 • (1/2)^ t/11
t = 56.5 days

What is the value of BD
Answers
Well, by the segment addition postulate, 3x + 5 + 5x - 7 = BD, so BD = 8x - 2.
Because you didn't include the instructions in the picture, I can't be sure if this is a rhombus or a rectangle, but if it is either, then 3x + 5 = 5x - 7, and x = 6
If this is true, then BD = 48 - 2 = 46, but only if the shape is either a rhombus or rectangle (or both would make it a square).
