A block of wood has a mass of 120g and a volume of 200cm3. What is the density of the wood?
Please provide an explanation!
Answer: [tex]0.6\ g/cm^3[/tex]
Step-by-step explanation:
We know that the formula to find density is given by :_
[tex]\text{Density}=\dfrac{\text{Mass}}{\text{Volume}}[/tex]
Given : Mass of block of wood = 120 g
Volume = [tex]200\ cm^3[/tex]
Then, the density of wood is given by :_
[tex]\text{Density}=\dfrac{120}{200}=0.6\ g/cm^3[/tex]
Hence, the density of wood = [tex]0.6\ g/cm^3[/tex]

What is the greatest 3 digit number you can subtract from 426 so that you would need to regroup?
Answer:
419
Step-by-step explanation:
Regrouping in subtraction: If we borrow from one group (tens group) and give to another (Once group) so that the operation can be completed, then this process is called regroup.
For example: We need to find the value of 52-39
[tex]52=50+2[/tex]
[tex]39=30+9[/tex]
We can not subtract 9 from 2. So we will borrow 10 from 50 and give to 2.
[tex]52=40+12[/tex]
Now,
[tex]52-39=(40+12)-(30+9)[/tex]
[tex]52-39=(40-30)+(12-9)[/tex]
[tex]52-39=(10)+(3)[/tex]
[tex]52-39=13[/tex]
We need to find the greatest 3 digit number that can subtract from 426 so that we need to regroup.
To use regroup, the once digit must be more that 6. So, maximum value for once place is 9.
Therefore, the greatest 3 digit number that can subtract from 426 by using regroup is 419.
4:189. Estimate the quotient
Final answer:
The estimated quotient of 4 divided by 189 is approximately 0.02, obtained by rounding 189 to 200 for easier calculation.
Explanation:
To estimate the quotient of 4 divided by 189, we can round the numbers to figures that are easier to work with and that will give us a ballpark figure of the actual quotient. Now, 189 can be rounded to 200 for estimation purposes because it is the nearest number that is easy to divide with 4. Then, we divide 4 by the rounded-up figure:
4 ÷ 200 = 0.02
This result indicates that the estimated quotient is 0.02. Keep in mind that this is a rough estimate and the actual quotient will be slightly higher since we rounded 189 up to 200.

a root beer factory produces 132 554 cases in 100 days. About how many cases does the factory produce in 1 day? round your answer to the nearest tenth of a case. Show yohr thinking on the number line.
The robot beer company produces [tex]\fbox{\bf1325.5}[/tex] cases in one day.
Further explanation:
Given:
There is a robot beer factory that produces 132554 cases in 100 days.
Calculation:
As it is know that m objects produces [tex]x[/tex] cases in [tex]n[/tex] days, then [tex]m[/tex] objects produces cases in 1 day is [tex]\dfrac{x}{n}[/tex].
As it is given that the robot beer factory that produces 132554 cases in 100 days.
That means robot factory has total 132554 case which is produced by the worker of this company in 100 days.
Then the robot beer factory produces [tex]x[/tex] cases in 50 days is,
[tex]\begin{aligned}x&=132554\times\frac{{50}}{{100}}\\&=66277\\\end{aligned}[/tex]
That means if the robot beer company works for 50 days then the company produces 66277 cases which is the half of the 132554 cases as the number of days reduces to half.
The robot beer factory produces [tex]x[/tex] cases in 1 days is,
[tex]\begin{aligned}x&=132554\times\frac{1}{{100}}\\&=1325.54\\\end{aligned}[/tex]
That means if the robot beer company works for 1 days then the company produces 1325.54 cases which is the one hundredth of the 132554 cases as the number of days reduces to hundred times.
Since, we have to round the cases up to one decimal, the robot beer company produces [tex]\fbox{\bf1325.5}[/tex] cases in one day.
The robot beer company produces [tex]\fbox{\bf1325.5}[/tex] cases in one day.

Keywords:robot, factory, beer, 132554, cases, 100, days, 1, time, work, ratio, multiplication, division, 1325.54, 1325.5, produces.
Factory produces 1325.5 cases to the nearest tenth in 1 day.
What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now it is given that,
Number of cases produced by factory = 132,554
Number of days = 100 days
Thus, Number of cases produce in 1 day = Number of cases produced / Number of days
⇒ Number of cases produce in 1 day = 132,554/100
⇒ Number of cases produce in 1 day = 1325.54
Round to nearest tenth, We look at the second decimal place which is 4
that is less than 5 so we leave the tenth place alone
⇒ Number of cases produce in 1 day = 1325.5
Thus, Factory produces 1325.5 cases to the nearest tenth in 1 day.

donovan. and three friends go to a fair they each spend 1/2 of their money on rides. then, they each spend $3 on food. at the end of the day, donovan and his friends have a total of $8 remaining how much money did each person spend
Answer:
Each person spent $10.
Step-by-step explanation:
Let the money spent by each friend = $x
Number of persons including Donovan = 4
Total amount spent by all friends all together = $4x
Since each spent half of their money on rides so amount spent on rides = [tex]\frac{4x}{2}[/tex] = $2x
Then they each spent $3 on food so total money spent = $(2x + 12)
Remaining money = $8
Now the equation will be
$4x - $(2x + 12) = $8
4x - 2x - 12 = 8
2x - 12 = 8
2x = 12 + 8
x = $10
Therefore, each friend spent $10.
To find out how much each person spent, we formulate a math equation representing each person's spending and savings, solve for the initial amount, and then subtract the remaining money.
Explanation:Let's start by stating the problem clearly. Donovan and three friends go to a fair. They each spend 1/2 of their money on rides. Then, each spends $3 on food. At the end of the day, they have a total of $8 remaining. To find out how much they each spent, we need to first work out the total amount of money they started with. Let's denote each friend's initial amount of money as X.
They each spend X/2 on rides and $3 on food. So at the end of the day, each has X - X/2 - 3 left. Sum this for Donovan and three friends and set this equal to $8. Therefore 4(X - X/2 -3) = $8. This equation can be used to solve for X, thus letting us know how much money each of them started with. See how much each spent by subtracting the remaining $2 (because $8 total remaining ÷ 4 = $2 per person) from this amount.

Which equation will help you solve this problem? Each boxcar in a toy train is the same length. There are 3 boxcars. Their total length is 21 inches. How long is each boxcar?
To find the length of each boxcar, we can use the equation length of each boxcar multiplied by the number of boxcars equals the total length. Applying this equation to the given problem, we find that each boxcar is 7 inches long.
Explanation:To solve this problem, we can use the equation
In this case, the length of each boxcar is the unknown we are trying to find, the number of boxcars is 3, and the total length is 21 inches.
So, the equation will be where x represents the length of each boxcar. To find x, we need to divide both sides of the equation by 3. Thus, x=7
Therefore, each boxcar is 7 inches long.
How do you write " Five less than the product of a number n and 26 is at least 8"
To write 'Five less than the product of a number n and 26 is at least 8', we can use an inequality to represent the given information.
Explanation:To write "Five less than the product of a number n and 26 is at least 8", we can use an inequality to represent the given information. The word "less than" suggests the use of the less than symbol '<'. 'Product' means multiplication, so we have n * 26. The word 'is' indicates the use of the equal sign '=', and 'at least' means greater than or equal to, so we use the greater than or equal to symbol '>='. Combining all the information, the equation becomes:
n * 26 - 5 >= 8
Using this equation, you can find the value of n that satisfies the inequality.
