Answer:
-6r+6
Step-by-step explanation:
Simplify
8−(6r+2)
Distribute the Negative Sign:
=8+−1(6r+2)
=8+−1(6r)+(−1)(2)
=8+−6r+−2
Combine Like Terms:
=8+−6r+−2
=(−6r)+(8+−2)
=−6r+6
-6r+6 is equivalent to 8-(6r+2)
bag is filled with 12 green marbles, 4 white marbles, and 2 blue marbles. What is the probability of drawing a marble that is blue?
A) 2% B)11% C)13% D) 20%
Answer:
B 11%
Step-by-step explanation:
The total number of marbles is
12+4+2 = 18
P( blue) = number of blue marbles / total marbles
= 2 blue/ 18 total
= 1/9
=.11111
= 11.11%
Please answer this correct
Answer:
C), or y = 200(1.18)^x, because we have 200 bacteria to start with and 1.18 because if you multiply something by 1.18 that is essentially 118% more than the number, or 18% more than the number.
Hope this helps!

WHAT VARIES MORE 6.6 OR 4.3
Drug Name Half-life
-----------------------------------
Acetaminophen 1-4 hours
Ibuprofen 1.8-2 hours
Loratadine 8.4 hours
Lithium 8 hours
Diphenhydramine 5.3-11.7 hours
The table above displays the half-lives of 5 common house hold drugs. The half-life (h) is the time is takes for a substance to reduce to half its initial value (A0). Half life can be used to solve for the amount (A) of a substance left after t time by using the following equation:
A=A^0⋅(12)^t/h
If Scott was administered 300 mg of Lithium, which of the following represents how much lithium, rounded to the nearest hundredth of a mg, could be left in Scott's blood stream after 12 hours?
Select one:
A. 157.23
B. 106.07
C. 212.17
D. 188.99
Answer:
B. 106.07
Step-by-step explanation:
To make use of the given formula for amount remaining, we need to know the original amount (300 mg), the elapsed time (12 h), and the half-life of the substance of interest (8 h).
SetupUsing the given formula with the relevant values, we have ...
A = (300 mg)·(1/2)^(12/8)
EvaluationUsing a calculator to evaluate this expression, we find the amount of Lithium remaining in Scott's system after 12 hours to be ...
A ≈ 106.07 mg

What is the value of x in the figure?
Enter your answer in the box.
x =
We need to do 90-61, which is 29. X = 29, because the base of 61 and the right of the x is equal to a right angle.
Answer:
x=29 degrees
Step-by-step explanation:
Both angles shown ad up to a 90 degree angle. We can see this because on the adjacent side there is a box indicating that it is a right angle. The three angles add up to 180, thus if we subtract 90 degrees due to the angle on the left of the y axis, the angles on the right of the y axis must add up to 90 as well.
Since the angles on the right must add up to 90, we set an equation to solve for x:
61+x=90(subtract 61)
x=29 degrees

Write an explicit formula for a , the nth term of the sequence 7, 14, 28, ...
Answer:
The sequence 7, 14, 28, ... is a geometric sequence with first term 7 and common ratio 2. The explicit formula for a geometric sequence is a_n = a_1 r^(n-1), where a_n is the nth term, a_1 is the first term, and r is the common ratio. In this case, a_n = 7 (2)^(n-1).
Here are the first few terms of the sequence:
n = 1: a_1 = 7
n = 2: a_2 = 14
n = 3: a_3 = 28
n = 4: a_4 = 56
n = 5: a_5 = 112
As you can see, the formula works for all values of n.

You are a waiter at a restaurant. A family had a bill of $116.17. They leave you a 20% tip. How much of a tip did you get?
Answer:
Hello there! :) The tip they would leave you would be of $23.23
Step-by-step explanation:
The first step is to devide 116.17 by 100, which would equal 1.1617, which is obviously not your answer or a valid amount of money. But, you now take this 1.1617 by 20. Why? Becuase 20% is the same as 20 out of 100. Now you multiply 1.1617 × 20 and you will get $23.23.

Step-by-step explanation:
I'm 43
Answer:
Length x height x width.
Step-by-step explanation:
Examples:
1 x 2 x 3 = 1 x 2 = 2 + 0 = 2 x 3 = 3 + 3 = 6 so the answer is 6.
2 x 3 x 2 = 2 x 3 = 3 + 3 = 6 x 2 = 6 + 6 = 12 so the answer is 12.
Here's one more in a different way:
3 x 5 x 4 = 5 + 5 + 5 = 15 = 15 + 15 = 30 x 2 = 30 + 30 = 60.
whats the slope and y-intercept sorry i keep getting it wrong
Answer:
-2 & 3/2
Step-by-step explanation:
=> -4x - 2y = -3
=> -4x + 3 = 2y
=> (-4/2)x + (3/2) = y
Compare this to y=mx+c
m=slope = -4/2 = - 2
y-intercept = c = 3/2
Answer:
2 & 3/2
