The half-life of a certain radioactive element is 35 hours. If there are 904 grams of this element, how much will be left after 70 hours? (please help I might fail Math.)
Answer:
226 grams
Step-by-step explanation:
The half-life of a radioactive substance is the time taken for half the quantity of the substance to decay such that the amount life after the given period of time is half the original quantity.
As such, given that the half-life of a certain radioactive element is 35 hours and there are 904 grams available, it means that after 35 hours,
Amount decayed = 1/2 * 904 grams
= 452 grams
Amount left = 904 grams - 452 grams
= 452 grams
After another 35 hours (now a total of 70 hours),
Amount decayed = 1/2 * 452 grams
= 226 grams
Amount left = 452 grams - 226 grams
= 226 grams

What is “rate of change”? Hint: it’s NOT “y=mx+b.” What term (begins with an S!) is it very closely related to?
Answer:
Standard Form
Step-by-step explanation:
Answer:
Rate of change refers to the change in one variable (i.e. independent variable) as a result of a change in another (i.e. dependant variable). A very common example is speed as it refers to the change in distance per a change in time. Graphically representing the relationship between two variables, the rate of change will be the gradient or slope of the graph.

Sara solved the equation -6(x-2) + 3x = -3(x+3) + 21 What is the solution?
pls help :)
To solve you can use inverse operations.
Here are the steps to find the answer:
1. Write out the equation: -6(x-2)+3x= -3(x+3) +21
2. Distribute both sides: -6x+12+3x= -3x-9+21
3. Simplify both sides: -3x+12=-3x+12
4. This equation is true for all values, or infinity, because the equation is the same on both sides

If the radius of a circle is multiplied by 3, which is true?
Answer:
I think that both are true...
If it's one, it's the circumference.
Step-by-step explanation:
So say the radius is x.
The area is πx^2
The circumference is 2xπ
If you multiply it by 3:
The area is 3πx^2
The circumference is 6xπ
Answer:
The circumference is tripled
Step-by-step explanation:
If the radius started as 2 the area would be 12.57 and the circumference would be 12.57.
Then if multiply the radius by 3 it would be 6 and the area would be 113.1 and the circumference would be 37.7.
12.57x3=37.7
Therefore the circumference triples when the radius is multiplied by 3.

Step-by-step explanation:
Here’s my dilemma, I can accept a $1000 bill or play a game ten times. For each roll of the single die, I win $500 for rolling 1 or 2, I win $400 for rolling 3; and I lose $300 for rolling 4,5,or 6. Based on the expected value, I should accept the $1000 bill.
Answer:
you should accept the $1,000 bill
Step-by-step explanation:
Given the information:
$500 for rolling 1 or 2$400 for rolling 3lose $300 for rolling 4,5,6P (rolling 1 or 2) = 1/6 + 1/6 = 2/6 = 1/3
P (rolling a 3) = 1/6
P (rolling 4 or 5 or 6) = 3/6 = 1/2
Hence, the expected value for 1 time is:
E = (1/3)*500 + (1/6)*400 - (1/2)*300
E = $166 + $66 - $150
E = $82
Expected value is linear so if you roll the die 10 times, expected value is: 10*82 = $820
The expected value is $82, meaning you should accept the $1,000 bill

Given f(x) - 3x= 1 and g(x) - 2x-3, for which value of x does g(x)= f(2)?
Answer:
Best Answer: f(x) = 3x - 1, g(x) = 2x - 3
f(2) = 3(2) - 1 = 6 - 1 = 5.
2x - 3 = 5
2x = 8
x = 4. This value ensures g(x) = f(2).

Each month, Daniel budgets $1230 for fixed expenses, $780 for living expenses, and $160 for
annual expenses. His annual net income is $30,300.
Which statement best describes his monthly budget?
It shows a deficit of $355
It shows a surplus of $355.
It shows a surplus of $515.
It is balanced.
Answer:
B
Step-by-step explanation:
Monthly net income = 30300/12 = $2525
Total monthly expenses = 1230+780+160 = $2170
Surplus = 2525 - 2170 = $355
The value of the cash flow will be $355 which is surplus. Then the correct option is B.
What is cash flow?The cash balance of liquid assets coming into and going out of a business is referred to as cash flow. Money spent and money received reflect inflows and outflows, respectively.
The cash flow is the difference between outflow and inflow.
Cash flow = outflow - inflow
If the value of the cash flow is negative that means the expense is more.
If the value of the cash flow is positive that means the income is more.
Every month, Daniel spending plans $1230 for fixed costs, $780 for everyday costs, and $160 for yearly costs. His yearly overall gain is $30,300.
Then the Cash flow is calculated as,
Cash flow = ($30,300 / 12) - ($1,230 + $780 + $160)
Cash flow = $2,525 - $2,170
Cash flow = $355
The value of the cash flow will be $355 which is surplus. Then the correct option is B.

Step-by-step explanation:
Pythagorean thm. says a^2+b^2=c^2 where a and b are the legs of the triangle and c is the hypotenuse.
The hypotenuse, c = 17
Leg b =8
a^2=c^2-b^2
a^2=17*17-8*8
a^2=289-64
a^2=225

Answer:
t = -4
Step-by-step explanation:
First you add the 7 on both sides and you get -6t=24. Then, you divide both sides by -6 to solve for t. And you get -4 as your answer. Hope this helped you.
-6t - 7 = 17
First add 7 to both sides of the equation.
-6t - 7 + 7 = -6t ,,,, 17 + 7 = 24
-6t = 24
Now divide 24 by -6.
24 ÷ -6 = -4
Answer:t = -4
Check:-6 × -4 = 24 ,,,, 24 - 7 = 17

7- (3 * 4)
Answer:
A 4* (7 - 3)
Step-by-step explanation:
Let's do this part by part. First we have "subtract 3 from 7:" this means we are taking 3 out of 7.
7 - 3
Next we have "then multiply by 4." So we need to take the above quantity and multiply the whole thing by 4.
(7-3) x 4

Find the next two terms of the sequence:

The next two terms of the sequence are
Answer:
The answer is 1690, and then 1630
Step-by-step explanation:
2050, 1990, 1930, 1870, 1810, 1750, 1690, 1630
Each number is going down by 60
===============================================================
Explanation:
This is an arithmetic sequence. We are adding -60 to each term to get the next term. Put another way, we are subtracting 60 from each term to get the next.
term 1 = 2050
term 2 = (term1) + (-60) = (term1) - 60 = 2050 - 60 = 1990
term 3 = (term2) + (-60) = (term2) - 60 = 1990 - 60 = 1930
term 4 = (term3) + (-60) = (term3) - 60 = 1930 - 60 = 1870
and so on
Keeping this pattern up, we get these next two terms
1750 - 60 = 1690
1690 - 60 = 1630
which are the two answers
-----------
If you want to use a formula, then a1 = 2050 is the first term and d = -60 is the common difference. We get this nth term formula
a(n) = a1 + d(n-1)
a(n) = 2050 + (-60)(n-1)
a(n) = 2050 - 60n + 60
a(n) = -60n + 2110
Then note that six terms of the sequence are given to us. This means we want to find the 7th term, so we plug in n = 7 to get
a(n) = -60n + 2110
a(7) = -60(7) + 2110
a(7) = -420 + 2110
a(7) = 1690
The 7th term is 1690
Repeat for n = 8
a(n) = -60n + 2110
a(8) = -60(8) + 2110
a(8) = -480 + 2110
a(8) = 1630
The 8th term is 1630
