This tree diagram shows the possible outcomes for tossing a nickel and tossing a penny. What is the probability of both coins landing tails up

Answer: 300 feet

Step-by-step explanation:

Note that:

.

Then the balloon rises at a constant rate of 30 meters per minute.

We can represent this situation through an arithmetic sequence as shown below

Where is the first term of the sequence and is the n-th term of the sequence and is the common difference between two consecutive terms.

In this case we look for the height of the balloon after 8 minutes.

Then we look for

Answer:

Step-by-step explanation:

You have an arithmetic sequence in which

a₁ =  90

a₂ = 120

a₃ = 150

1. Calculate the explicit formula

This is an arithmetic sequence, because there is a constant difference of 30 between consecutive terms.

The explicit formula for the nth term of an arithmetic sequence is

aₙ = a₁ + d(n - 1 )

a₁ is the first term, and d is the difference in value between consecutive terms. Thus,  

aₙ = 90 + 30(n - 1) = 90 + 30n - 30

aₙ = 30n + 60

2. Calculate the eighth term

a₈ = 30 × 8 + 60 = 240 + 60 = 300

Answer:

y=1/10C-23/8x

Step-by-step explanation:

Linear Equation:

Ax+By=C

Slope Intercept Form:

y=mx+b

So, the linear equation is the following;

28.75x+10y=C

Now, to change it into slope intercept form you must get 'y' alone;

28.75x+10y=C

-28.75x         -28.75x            

_________________

10y=C-28.75x                        

10y/10=C/10-28.75x/10

y=1/10C-23/8x
