Answer:
Given is a sculpture that is built up of metal and wood, and the weight of this sculpture is 14.9 kilograms.
It says that three-fourth of the total weight is metal and says to find the weight of wooden part.
We can find the weight of metal part and then subtract it from the total weight to calculate the answer.
Step-by-step explanation:
Total weight = 14.9 kilograms.
Metal part = three-fourth of total weight =
Wooden part = 14.9 - 11.175 = 3.725 kilograms.
Hence, the wooden part is 3.725 kilograms.

Suppose Enrique has two building blocks. The area of one face of one of the blocks is 4 square centimeters and the area of the face of the other block is 100 square centimeters. What is the scale factor from the smaller block to the larger block?
Answer:
I think the larger block has a scale 25 times bigger than the smaller block since 100 divided by 4 equals 25
Please tell me if I'm wrong
I hope this helps
:D
Answer:
The Scale factor is 5.
Step-by-step explanation:
Because the area has cm^2 to find the scale factor you find the number it takes to get from one area to the next and take the square root.
4X = 100
X = 100/4
X = 25 (Take the sqrt because of area)
X = sqrt(25)
X = 5
The Scale factor is 5.
The mass of 1 L of water is 1 kg. The mass of gasoline is 0.68 times the mass of water. What is the mass of the gasoline in a full tank that holds 75 L.
Hence, the mass of the gasoline in a full tank that holds [tex]75L[/tex] is [tex]680[/tex]grams.
What is the mass?
Mass refers to the quantity of matter in an object. Mass is generally measured by how much something weighs. The more matter something has, the more it will weigh.
Here given that,
The mass of [tex]1[/tex] L of water is [tex]1[/tex] kg. The mass of gasoline is [tex]0.68[/tex] times the mass of water.
As we know,
[tex]1L=1000ml[/tex]
So, [tex]0.68[/tex]×[tex]1000=680grams[/tex]
As per this the mass of water is greater than the mass of gasoline.
Hence, the mass of the gasoline in a full tank that holds [tex]75L[/tex] is [tex]680[/tex]grams.

Answer:
Melinda saves 2 less dollars than Marcus each week.
Step-by-step explanation:
Y = 12x + 75 is Melinda's equation. Y = 14x + 25 is Marcus's equation. First we'll disregard how much money they have saved already to see how much they save weekly. So Melinda's new equation is Y = 12x, and Marcus's new equation is Y = 14x. Now we'll do Marcus's equation (14x) - Melinda's equation (12x) to see how much more money Marcus saves each week, which will in turn will tell us how much less money Melinda saves each week.
14 x - 12x = 2. (x-x=0) This tells us Marcus saves 2 more dollars than Melinda each week.
Which gives us our answer, Melinda saves 2 less dollars than Marcus each week.

What is the value of the expression when c=0 and d=-6 ?
cd-d2/4
Answer:
-9
Step-by-step explanation:
This what you wrote:
[tex] cd - \dfrac{d^2}{4} = [/tex]
[tex] = (0)(-6) - \dfrac{(-6)^2}{4} [/tex]
[tex] = 0 - \dfrac{36}{4} [/tex]
[tex] = -\dfrac{36}{4} [/tex]
[tex] = -9 [/tex]
Maybe this is what you meant to write:
[tex] \dfrac{cd - d^2}{4} = [/tex]
[tex] = \dfrac{(0)(-6) - (-6)^2}{4} [/tex]
[tex] = \dfrac{-36}{4} [/tex]
[tex] = -9 [/tex]

if you have a bacteria cell that you touch at 9:00 am (so now you have one cell on you) and it multiplies every 20 mins how much will i have on me at 4:00
Well, 9:00 AM to 4:00 PM would be 7 hours. 7 hours into minutes would be 420. 420 divided by 20 is 21. This means it multiplies 21 times from 9:00 to 4:00. Since it multiplies by 2, than you need to skip count with the pattern multiply by 2 and stop once you have 21 numbers.
1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, 65536, 131072, 262144, 524288, 1048576. That would be 21 numbers.

A summer camp cookout is planned for the campers and their families. There is room for 200 people. Each adult costs $4, and each camper costs $3. There is a maximum budget of $750. Write the system of inequalities to represent this real-world scenario, where x is the number of adults and y is the number of campers. x + y ≤ 200 4x + 3y ≤ 750 x + y ≤ 750 4x + 3y ≤ 200 x + y ≤ 200 3x + 4y ≤ 750 x + y ≤ 750 3x + 4y ≤ 200
Answer:
I think its A
Step-by-step explanation:
The required system of inequalities is x + y ≤ 200 and 4x + 3y ≤ 750. Hence, the first option is the correct choice.
What is inequality?Inequality is a non-equal relation between two expressions involving variables and constants.
The sign of the inequality can be, less than (<), greater than (>), less than or equal to (≤), or greater than or equal to (≥).
How to solve the question?In the question, we are asked to write the system of inequalities to represent the given scenario, where x is the number of adults and y is the number of campers.
We are informed that there is a room for 200 people.
Thus, the total number of people, that is, the number of adults + the number of campers, or, x + y should be less than or equal to 200.
This gives us an inequality:
x + y ≤ 200.
We are informed that the cost of an adult is $4 and the cost for a camper is $3, and the total budget is $750.
Thus, the total cost, that is, the cost of all adults + the cost of all campers, or, 4x + 3y should be less than or equal to 750.
This gives us an inequality:
4x + 3y ≤ 750.
Thus, the required system of inequalities is x + y ≤ 200 and 4x + 3y ≤ 750. Hence, the first option is the correct choice.

evaluate this expression when c= -2 and d= 2:
Step-by-step explanation:
you just have to put the given values in place of the variable names and then simply calculate.
(-2² + 2²) - 2(-2² - 2²) = (4 + 4) - 2(4 - 4) = 8 - 2×0 = 8
so, B is the right answer.
please remember the correct sequence of operations :
first are brackets.
then exponents.
then multiplications and divisions.
and then (at last) additions and subtractions.
and also please remember : multiplying a negative number with a negative number creates a positive result.
that is of course also true for squaring a negative number, as ² just means that the negative number is multiplied with itself.
now you also know the result of -2³, right ?
as this means -2 is multiplied 3 times by itself. what does that do to the sign ?
-2 × -2 = 4 (positive).
but now we have to multiply a third time
4 × -2 = -8 (because multiplying a positive number with a negative number creates a negative result).
a stack of 500 pieces of paper is 1.875 inches tall derion guesses that each piece of paper is 0.015 inches thick. explain how you know that derions answer is not correct.
compute the thickness of each piece of paper. show your reasoning
Answer:
Derions answer is not correct becuase 500 x 0.015=7.5 inches. If he got this as an answer that would meen that the stack of paper is 7.5 inches tall, which is not correct.
If we divide 1.875 by 500 we get 0.00375 which is the thickness of each sheet of paper.
Done the first two but i dont know how to do the mean of it
To find mean:
1) Add up all data values to get the sum
2) Count the number of values in your data set
3) Divide the sum by the count
First we have to find all the data values. We do this by finding all of the peas, not just the information numbers of peas in a pod.
4 x 2 = 8
5 x 10 = 50
6 x 18 = 108
7 x 14 = 98
8 x 6 = 48
8 + 50 + 108 + 98 + 48 = 312 total number of peas
2 + 10 + 18 + 14 + 6 = 50
312 / 50 = 6.24 peas per pod
So in our example the mean number of peas in a pod is 6.24.
I hope this helps! :)
