Answer:

0.64

Step-by-step explanation:

4 out of 5 free throws is 0.8 as a decimal.

The probability that Brian will make <em>2 free throws</em> is 0.8 for the first one, and then 0.8 of that for the second one. That means you multiply the two to get your answer and 0.8 times 0.8 = 0.64.

The half-life of a radioactive kind of tellurium is 25 minutes. If you start with 88 grams of it, how much will be left after 50
LUCKY_DIMON [66]

Notice that 50 minutes is twice the half-life.

After 25 minutes, half of the starting amount remains, so that 88g decays to 44g.

After another 25 minutes (a total of 50 minutes), the 44g will decay to 22g.

bonufazy [111]

Answer:

y = 2

Step-by-step explanation:

Given

\frac{2y-1}{15} = \frac{y}{10} ( cross- multiply )

10(2y - 1) = 15y ← distribute left side

20y - 10 = 15y ( subtract 15y from both sides )

5y - 10 = 0 ( add 10 to both sides )

5y = 10 ( divide both sides by 5 )

y = 2

Solve by substitution. Show each step of your work.
zaharov [31]

5x + y = 15

y = -5x + 15

Substituting y= -5x+15 from first equation into second equation:

3x + 2y = 16

3x + 2·(-5x + 15) = 16

3x - 10x + 30 = 16

-7x + 30 = 16

7x = 30 - 16 = 14

x = 2

Substituting x=2 into the first equation:

5x + y = 15

5(2) + y = 15

10 + y = 15

y = 15 - 10

y = 5

So your final answers are x=2 and y=5.
