Answer:
It seems there's more information in you question that you haven't posted.
7 months = 7 * (365/12) = 213 days
The half-life of chromium 51 is 27.7 days.
After 7 months, chromium 51 will have undergone 7.69 half-lives.
To solve for the ending amount we'll use the formula:
Ending Amount = Beginning Amount / 2^n where 'n' = # of half-lives
We'll say the beginning amount =1
Ending Amount = 1 / 2^7.69
Ending Amount = 0.0048426082
Basicaly if you started with 1 gram of chromium 51, after 7 months you would have 0.0048426082 grams.

Step-by-step explanation:
Answer:
since the formula of a triangle is ab/2 and since there is four simply multiply 3x4 which is 12 and divide by 2 which is 6 and 6x4= 24 and add that tp 9 since the base is just 3x3 which results for an answer of 33.

The given differential equation is :
xy′−3y=6
We want to determine which of the following options is a solution to the differential equations.
The function that satisfies the differential equation is a solution.
We can verify that
satisfy this differential equation.
We differentiate to get:
We substitute the function and its derivative into the differential equation to get:
We expand and simplify on the left:
This simplifies to:
Verified.
We can show that all the other functions do not satisfy this differential equation
Answer:
x = 100
Step-by-step explanation:
Alex's house (point F) lies on the same street as her school (point H). Alex's bus stop (point G) lies between her house and her school. Given FG=2x meters, GH=1,000 meters and FH=1,200 meters. What is the value of x in meters?
FG=2x meters, GH=1,000 meters and FH=1,200 meters.
FH = FG + GH
1200 = 2x + 1000
1200 - 1000 = 2x
200.= 2x
x.= 200/2
x = 100
Answer:
2√3
Step-by-step explanation:
So √12 is in radical form. I think what you are asking for is to reduce the expression to its **simplest** readical form.
So 12 = 4*3, √12 = √4 * √3.
So 12 = 4*3, √12 = √4 * √3.
We can ‘reduce’ this by noting that √4 =2, so the expression becomes 2√3.
This cannot be further reduced because 3 isn’t a square or divisible by a square, so 2√3 is the simplest radical form.
