You look at the tenths place(the number behind the decimal) then you look at the the numbers behind it if the one directly behind it is more than five then you round it up one so like this would be 4.000 because u leave the number in front alone until you have figured the other things out so leave the three alone for right now the look at the nine then look at the eight it is more than five so you round the nine to ten(which would be 4) then turn everything else to zeros so the answer is 4.000 or just 4

PLEASE HELP ME! A skydiver parachutes to the ground. The height y (in feet) of the skydiver after x seconds is y = -10x + 3000.
tatuchka [14]
A) Plot a point at (0, 3000), then subtract 10 for every second that passes by.
B) The slope is negative because the skydiver is falling and the graph is plotting his descent, his x intercept is at (300, 0) which means he will touch land after 300 seconds
To find the the x intercept, make y equal 0 so 0=-10x+3000, subtract by 3000 on each side, and you end up with -3000=-10x, you then divide both sides by -10 and you end up 300=x or x=300

A soccer team uses 5-gallon coolers to hold water during games and practices. Each cooler holds 640 fluid ounces. The team has s
polet [3.4K]
<h3>Answer:   640c - 6.25s - 8.75g</h3>

===============================================

Work Shown:

s = number of small cups

g = number of large cups

c = number of coolers

----------

1 cooler = 640 fluid ounces

c coolers = 640c fluid ounces

1 small cup = 6.25 fluid ounces

s small cups = 6.25s fluid ounces

1 large cup = 8.75 fluid ounces

g large cups = 8.75g fluid ounces

----------

T = total amount of water poured

T = (amount from small cups) + (amount from large cups)

T = 6.25s+8.75g

L = amount of water left

L = (original total amount of water) - (amount of water poured out)

L = 640c - T

L = 640c - (6.25s+8.75g)

L = 640c - 6.25s - 8.75g

How many times greater is the value of the 4 in 4,735 than the value of the 4 in 6,412? How many times greater is the value of t
nalin [4]

Answer:

10 times

Step-by-step explanation:

Since the leftmost value is called ones place.

the second leftmost value is called tens place.

the third leftmost value is called a hundred place.

the fourth leftmost value is called a thousand place and so on.

So, The value of 4 in 4,735 is 4 thousand = 4,000

and the value of 4 in 6,412 is 4 hundred = 400.

Hence, the value of the 4 in 4,735 is 10 times the value of the 4 in 6,412.
