4,000,000
because the hundred thousand place value is the digit 5 or higher, the millions rounds up!! in this case, the 3 in the millions rounds up to 4 and the rest of the digits on the right turn to 0, also remember commas!!!!!
3 887 860 rounded to the nearest million is 4 000 000.
From the given number 3 887 860, stating the place value of each digit
We have 0 ones (or unit), 6 tens, 8 hundreds, 7 thousands, 8 ten thousands, 8 hundred thousands and 3 million.
Hence, the number we are rounding is 3 (since we are asked to round to the nearest million)
To round a number, we either round up or round down.
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down; and if the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.
Since, the number that follows the digit we are rounding is 8, then we round up. We round up by adding 1 to the digit we are rounding and turn the remaining numbers to zeros.
(3+1 = 4)
Hence, 3 887 860 rounded to the nearest million is 4 000 000.

2. If you know the volume of a cube, how do you find its
edge length?
nel
[tex]\huge\boxed{\sqrt[3]{\text{V}}}[/tex]
The volume of a cube is found by cubing the edge length — or multiplying it by itself twice.
In other words, the volume of a cube is as follows:
[tex]V=e*e*e[/tex]
Simplified:
[tex]V=e^3[/tex]
To find the edge length from the volume, you'd have to do the opposite, which is to find the cubic root.
To make the sum or difference of 3/4+1/3
Answer:
13/12 or 1 1/12
Step-by-step explanation:
First, I like to line up the fractions like this:
3/4
1/3
You can't add them yet because they have different denominators, so we have to get them to the same denominator first. What is a number 3 and 4 can be multiplied by? Let's use 12. So, we want both of their denominators to be 12. How do we do that? 4 times what equals 12? 3. However, whatever you multiply the denominator by, you have to do to the numerator as well. Here is what we have:
3/4 x 3
1/3
3x3 equals 9, so your first fraction is 9/12. Then, do the second fraction. 3 times what equals 12? 4. So, multiply the numerator, 1, by 4 to get 4. So, your second fraction is 4/12. Now, you have to add them together, 9+4 = 13. The denominator stays the same. So, your sum is 13/12. If you want to, you can also simplify it to a mixed number into 1 1/12.

Alice has 800 MB of data. Bob has 1500 MB of data. Jack has 750 MB of data. Will it all fit on Alice's 4 GB thumb drive?
Answer:
Ill walk you through
Step-by-step explanation:
How many MBs are in a GB??
Remember that 1000 MB = 1 GB.
Start by adding together all the MB values.
800 MB + 1500 MB + 750 MB = 3050 MB.
Next, convert to GB by dividing by 1000.
3050 MB / 1000 = 3.05 GB
Since 3.05 < 4, YES. It will all fit in Alice's 4 GB thumb drive.

The bartender of a poolside bar prepares 96 fluid Ounces of mocktail by blending
the juice of cranberries and oranges. He uses three times the amount of cranberry
juice than orange juice to prepare the mocktail. He also adds 24 ounces of lemon
extract. How many fluid Ounces of orange juice was used in all?
Cloubt 1tbe ofroncorn
Answer:
18
Step-by-step explanation:
cranberries, oranges and lemon extracts makes =96 fluid Ounces of mock-tail
i.e cranberries+oranges+lemon extracts=96 fluid Ounces of mock-tail....... (1)
let fluid ounces of orange=xthen fluid ounces of cranberry=3x; \\ because it is three times of orangeand lemon extract is given as 24 ounces.putting these values in (1), we get
[tex]3x+x+24=96[/tex]
[tex]4x+24=96\\4x=96-24\\4x=72\\x=\frac{72}{4}\\ x=18[/tex]
fluid Ounces of orange juice was used in all=18
Final answer:
To find the amount of orange juice used in the mocktail, we set up an equation and solve for 'x'. We find that the bartender used 18 fluid ounces of orange juice in the mocktail.
Explanation:
To find the number of fluid ounces of orange juice used, we need to set up an equation. Let's say the amount of orange juice used is represented by 'x'. According to the problem, the amount of cranberry juice used is three times the amount of orange juice, so it can be represented as '3x'.
We know that the total amount of mocktail prepared is 96 ounces, and the lemon extract added is 24 ounces. So, we can set up the equation: x + 3x + 24 = 96. Simplifying this equation, we get 4x + 24 = 96.
Next, we need to isolate 'x'. Subtracting 24 from both sides of the equation, we get 4x = 72. Dividing both sides by 4, we find that x = 18.
Therefore, the bartender used 18 fluid ounces of orange juice in the mocktail.

A manufacturing plant is looking at units shipped for a 3-year period. In 2005, the plant shipped 12,500 units. In 2008, the
plant shipped 16,000 units. Find the rate of change of units shipped over the 3-year period.
A. 3,500/
2,008
B. 3,500/
2,005
C. 3,500/3
D. 9,500
Option C - 3500/3
Step-by-step explanation:
Step 1 :
Number of units shipped in the year 2005 = 12,500 units
Number of units shipped in the year 2008 = 16,000 units
Time period = 3 years
We have to determine the rate of change of units over the 3 year period. This is obtained by dividing the difference in units by the time period.
Step 2:
The difference in units over the 3 year period = 16000 - 12,500 = 3500 units.
Hence the required change rate over the 3 year period = 3500/3
Option C is the answer.

What is the algebraic way to solve 2000 (X -0.03)= 6000 by using the dividing each side first method
To solve the equation 2000 (X - 0.03) = 6000, divide both sides by 2000 to get X - 0.03 = 3, and then add 0.03 to each side to find X = 3.03.
Explanation:To solve the algebraic equation 2000 (X - 0.03) = 6000 using the divide each side method, we can follow these steps:
Divide both sides of the equation by 2000 to isolate the term with the variable X.This simplifies the equation to X - 0.03 = 3.Add 0.03 to both sides to solve for X.This gives us X = 3.03 as the solution.Now X has been isolated, and we have found the value that satisfies the equation.
a square green rug has a yellow square in the center. The side of the yellow square is x inches the width of the green band that surrounds the yellow square is 7 inches. What is the area of the green band?
Answer:
28x +196 in^2
Step-by-step explanation:
The outside dimension of the square green rug is (x+14), so its area is (x+14)^2. The area of the green band will be the difference between this and the area of the yellow square, (x^2).
green band area = (x +14)^2 -(x^2) = x^2 +28x +196 -x^2
green band area = 28x +196 . . . . square inches

1,500 crickets
1,600 crickets
2,000 crickets
1,638,400 crickets
Answer:
Starting population of crickets is 50. It doubles in size every 4 months.
5 years = 60 months
60 : 4 = 15
The equation is:
f ( x ) = 50 * 2^x ( an exponential function )

(-0,0) U(39) U (18,co), but only [18,00) contains viable times for machine 1
Answer:
its B
Step-by-step explanation:
after you find the intervals. you also need to consider that the plant manager knows the two machines will take at least 6 hours, so (0, 3] is taken out of the picture leaving you with B
The correct answer choice is:
(-0,0) U (3,9) U (18,∞), but only the interval [18,∞) contains viable times for machine 1.
Here, we have,
The given inequality represents the condition that the task should take at least 6 hours to complete.
Let's analyze the answer choices:
(0.31 U 9.18] both contain viable times for machine 1:
This answer choice includes the interval (0.31, 9.18], which contains values less than 6.
Therefore, it does not satisfy the condition of at least 6 hours.
(0, 3] U (9,18]; only (9, 18] contains viable times for machine 1:
This answer choice includes the intervals (0, 3] and (9, 18].
Both of these intervals contain values less than 6, so they do not satisfy the condition of at least 6 hours.
(-∞,0) U (13,9) U (18,∞), no interval contains viable times for machine 1:
This answer choice does not include the interval (0, 3] where viable times for machine 1 exist.
(-0,0) U (3,9) U (18,∞), but only [18,∞) contains viable times for machine 1:
This answer choice includes the intervals (0, 3] and (18,∞), which contain viable times for machine 1. However, the interval [18,∞) specifically represents viable completion times for machine 1.
Therefore, the correct answer is (-0,0) U (3,9) U (18,∞), but only the interval [18,∞) contains viable times for machine 1.
