Given two points (x₁,y₁) and (x₂,y₂), the midpoint of the segment will be:
( (x₁+x₂) / 2 , (y₁+y₂)/2  ).
In this case:
J(-3,18)
T(7,-10)

The midpoint will be:
( (-3+7)/2  ,  (18-10)/2 )=(4/2 , 8/2)=(2, 4).

Answer: the midpoint of segment JT is (2,4)

Iodine-125 has a half-life of about 60 days. How many milligrams of a 1000 mg sample will remain after 240 days?
Tomtit [17]

240 days is 4 times the half-life, which means that a sample of 1000 mg will decay to

\dfrac{1000}{2^4}=\dfrac{125}2=62.5\,\mathrm{mg}

after 240 days.

<u>Step-by-step explanation:</u>

Blue = 5, Red = 3, Green = 2, Total = 10

Probability   =  First draw    and      Second draw

                    =        \frac{5}{10}             x                 \frac{2}{10}      

                    =                      \frac{10}{100}

The circle graph shows how the annual budget for a company is divided by department. If the amount budgeted for Media and Sales
Tcecarenko [31]

Answer:

125,000,000

Step-by-step explanation:

In percentage,

Media + Sales = 3 + 17 = 20%

Let total budget be "t", so we can say:

20% of total budget is 25,000,000

"of" means "multiplication" and "is" means "equal to", so we can convert word equation to algebraic equation. Shown below:

20% * t = 25,000,000

20% = 20/100 = 0.2

Thus, the final equation is:

0.2t = 25,000,000

Solving for t, we get:

0.2t = 25,000,000\\t=\frac{25,000,000}{0.2}\\t=125,000,000

The total budget is (125 million) = 125,000,000
