Answer: -8

Step-by-step explanation:

We must remember that, in geometric sequences, the ratio between the consecutive terms is constant.This is called "Common ratio" and is represented with "r".

We need to find the common ratio of this geometric sequence:

Divide one term by the previous term:

$r=\frac{-4}{-2}\\\\r=2$

Then, the next term asked in the exercise can be found by multiplying -4 by 2.

Therefore, this is:

$next\ term=(-4)(2)\\\\next\ term=-8$

2 1/2 ÷ 1 5/8 =<br><br> Two and a half divided by one and five eights

LUCKY_DIMON [66]

So first of all we can't start by changing them both into improper fractions

So it would be:
5/2 divided by 13/8
From there you would do 5/2 * 8/13 which could convert to
5/1 * 4/13 which would be 20/13

A freight train leaves a station and travels north at 60 mph. 4 hours later, a passenger train leaves on a parallel track and t

harkovskaia [24]

Answer:

first do:

60mph * 4 hours= 240mi

Let D = the distance the passenger train has to

travel to catch the freight train

Start a stopwatch when the passenger train leaves

Let t = the time on the stopwatch when they meet

Equation for freight train:

d-240=60t

Equation for passenger train:

d=100t

all together:

100t-240=60t

we can do 100t-60t because they both have (t)= 40t

40t=240 *now divide 240 by 40= 6

THEN do:

D= 100mph x 6= 600mi

They will meet 600 mi from the station

to check:

d-240=60t x 6

600-240= 360

60 x 6= 360

360=360

The numbers on a football field indicate 10 yard increments. You walk around the perimeter of a football field between the pylon

Roman55 [17]

Answer:

5,333 square yards.

Step-by-step explanation:

Football fields have standard 100 yards length, if you walk the perimeter of a football field you will walk the twice the length and twice the width. Therefore, the width of the field can be found as follows:

$306.667 = 2L +2W\\W = \frac{306.667 - 2*100}{2} \\W= 53.33$

The area of the playing field is the product of the length by the width

$A = L*W\\A= 100*53.33\\A=5333$

The area of the playing field is 5,333 square yards.
