Answer:

Step-by-step explanation:

The problem, in part, that you are having is that you are giving fractions for answers and they want miles.

1 whole trip = 1000 miles

3/8 of a trip = x miles.

You have a proportion

1/(3/8) = 1000/x Cross multiply

1 *x = (3/8) * 1000 Combine of the left. Multiply on the right.

x = 3/8 * 1000

x = 3000 / 8

x = 375 miles.

If Ryan has already driven 375 miles, then how many miles remain?

James faces 1000 - 375 = 625 miles.

James wisely decided that he is only going to drive 2/5 of what is left.

625 * 2/5 = 1250/5 = 250 miles.

Answer

Ryan 626 miles

James 250 miles

brilliants [131]

To find the third side of a triangle (there are two answers you could get), you need to use the Pythagorean formula: a^2+b^2=c^2. First answer, 20^2+30^2=c^2. Solve for c. c=36.06. The second answer, 20^2+b^2=30^2. Solve for b. b=26.36.

In 1985, there were 285 cell phone subscribers in Arlington. The number of subscribers increased by 75% per year since 1985. Fin

ANTONII [103]

Answer:

The number of subscribers in 2008 is 110,845,988

Step-by-step explanation:

The number of cell phone subscribers in Arlington, in t years after 1985, can be modeled by the following equation.

$N(t) = N(0)(1+r)^{t}$

And which N(0) is the number of subscribers in 1985 and r is the rate it increases per year, as a decimal.

In 1985, there were 285 cell phone subscribers in Arlington.

This means that $N(0) = 285$

The number of subscribers increased by 75% per year since 1985.

This means that $r = 0.75$

$N(t) = 285(1.75)^{t}$

Find the number of subscribers in 2008.

2008 is 2008-1985 = 23 years after 1985. So we have to find N(23).

$N(23) = 285(1.75)^{23} = 110,845,988$

The number of subscribers in 2008 is 110,845,988

Find the numerical values of -3|x|+2x-1 if x=-5. PLSSSS HELP

Kisachek [45]

Answer:

Step-by-step explanation:

Since x = -5, we can replace x with it's numerical -5, right? The problem tells you that x is equal to -5. So, just replace any x you see with -5.

So in this case,

$-3|x|+2x-1$

turns into:

$-3|(-5)|+2(-5)-1$

You can use a calculator or solve it by hand to see what the answer is.

$-3|(-5)|+2(-5)-1\\-3(5)+2(-5)-1\\-15+(-10)-1\\-25-1\\-26$
