A lake is 200 feet wide. Two boats start to move towards one another from opposite shores. In one minute, the first boat goes 40

NARA [144]

Answer:

I use faction

Step-by-step explanation:

The first boat.

$\frac{40 feet}{60 seconds}$ ÷ 10 = $\frac{4 feet}{6 seconds}$

$\frac{4 feet}{6 seconds}$ ÷ 2 = $\frac{2 feet}{3 seconds}$

The first boat move $\frac{2 feet}{3 seconds}$

The second one do the same

$\frac{30 feet}{60 seconds}$ ÷ 10 = $\frac{3 feet}{6 seconds}$

$\frac{3 feet}{6 seconds}$ ÷ 2 = $\frac{1.5 feet}{3 seconds}$

That is the speed of each boat.

The first boat need 50 minutes to get to the other side

2000 ÷ 2 =1000

1000 x 3 = 3000

3000 ÷ 60 = 50

The second boat need 66.6666666667 minutes to get to the other side

200 ÷1.5 = 1333.33333333

1333.33333333 x 3 = 4000

4000 ÷ 60 = 66.6666666667

What is the coefficient of the term 67xy 1/7, 6, 6xy, and 6/7 Which one do I pick?

Scorpion4ik [409]

You would pick You would choose 6xy, or 67xy, unless that is with the 1/7,
and this is because the definition of a coefficient is "<span>a numerical or constant quantity placed before and multiplying the variable in an algebraic expression",
so both of these have variables.</span>
