Write a formula that shows the dependent of the mass of a piece of cork on its volume note the density of the cork is 0.18 g/cm^3. Then use the formula to find the answer.
The volume of a piece of cork with a mass of 64.8g
Answer:
43.2 grams
Step-by-step explanation:
We will use density formula to solve our given problem:
he mass of a piece of cork with a volume of 240 cm³ is 43.2grams
The formula for calculating the density of a substance with mass "m" and volume "v" is expressed as:
m is the mass of the substance
v is the volume of the substance
Given the following parameters
Density = 0.18g/cm³
Volume = 240cm³
Substitute the parameters into the formula to get the mass:

Hi there!
We know that:
m∠WXZ = 112°
Since m∠1 is 48° greater than m∠2, we can write an expression:
m∠2 = x°
m∠1 = (x + 48)°
Since both angles sum up to m∠WXZ, we can write this as:
112° = x° + (x + 48)°
Solve for x:
112 = 2x + 48
64 = 2x
x = 32°

the water slide is 6 feet tall and the end of the slide is 9 feet from the base of the ladder about what slope does the slide have?
The slope of an object is the ratio of the rise to the run. It measures the degree of steepness of an object or a projection. Hence. The slope of the slide is 1.5
Height of water slide = 9 feetsHorizontal length = 6 feetsSlope = Rise / Run
From the question ;
Height of water slide = Rise Horizontal length = RunHence,
Slope = 9 / 6 = 3/2 = 1.5
Therefore, the slope of the water slope ls 1.5.

For g(x) = −4x, find g(x) when x = −6 and when x = 2.
answer;
when x=-6
g=4
when x=2
g = 4
Step-by-step explanation
every where you see x put -6 there
g(-6)=4(-6)
-6g=-24
-6g/-6=-24/-6
g=4
when x= 2
anywhere you see x put 2 there
g(2)=4(2)

Step-by-step explanation:
First we divide 1125 by 225 to get the ratio of the two distances. We can see that 1125 goes into 225 exactly 5 times. Then we do 5 times 3 to get 15.

Indira is climbing and starts at 182.5 meters above sea level each hour she descends 36.5 meters the table shows the function relating in inDara‘s height to the number of hours she mountain climbing
The function relating in indira‘s height to the number of hours she mountain climbing is: y = -36.5x + 182.5
A linear equation is given by:
y = mx + b;
where m is the slope(rate of change), b is the initial value of y, y is the dependent variable and x is the independent variable.
Let x represent the number of hours spent climbing the mountain and y represent the distance above see level.
She starts at 182.5 meters above sea level, hence; b = 182.5 meters
She descends 36.5 meters each hour, hence m = -36.5 meter per hour
Therefore the equation becomes:
y = -36.5x + 182.5

Yesterday the children at Deion’s preschool chose to pursue various play with stuffed animals 15, read books 2, paint 1, play math game 1, Based on past data, if 24 preschoolers are at school today, how many should you expect to read books?
Based on past data, we can expect that 2 preschoolers will be reading books today out of the total of 24 preschoolers present. we can apply this ratio to the total number of preschoolers present today.
To determine the expected number of preschoolers who should be reading books today, we can use the ratio of the number of preschoolers who chose to read books yesterday to the total number of preschoolers present yesterday.
Yesterday, there were 24 preschoolers present, and 2 of them chose to read books. Therefore, the ratio of preschoolers reading books to the total number of preschoolers yesterday is:
2 / 24
To find the expected number of preschoolers reading books today, we can multiply this ratio by the total number of preschoolers present today (which is 24):
(2 / 24) * 24
Simplifying this expression, we find:
2

Part A: Write a sentence to describe the number of cups of yellow paint that Greg mixed with each cup of blue paint. (4 points)
Part B: How many cups of blue paint should Greg add to each cup of yellow paint to make the shade of green? Explain your reasoning. (4 points)
Part C: If Greg purchased 6 cups of yellow paint for $54, what is the unit price per cup of yellow paint? (2 points)
(GIVING 15 points)
Answer:
Part A: A ratio of 2:1 means that he uses 2 cups of yellow paint for each cup of blue paint.
-------------------------------------------------------------------------------------------------
Part B: The ratio of yellow to blue is 2:1 = 2/1. So, if for 2 yellow is 1 blue, then for 1 yellow is x:
2/1 = 1/x
x = (1*1) / 2
x = 1/2
For each cup of yellow paint, Greg should add 1/2 cup of blue paint.
-------------------------------------------------------------------------------------------------
Part C: 6 cups cost $54, then 1 cup cost:
54 / 6 = 9
The price per cup of yellow paint is $9.
A. The number of cups of yellow paint that Greg mixed with each cup of blue paint is (1/2) cup.
B. Greg should add 2 cups of blue paint to each cup of yellow paint.
C. The unit price of per cup of yellow paint is 9 dollars.
What is the ratio?The ratio compares similar quantities in simplest form.
Given that the ratio of the number of cups of yellow paint to the no. of cups of blue paint to make a green shade paint is 2:1.
This can also be written as
(yellow paint/blue paint) = (2/1).
∴ 1 cup of yellow paint and 2 cups of blue paint is required to make a green shade of paint.
A. The number of cups of yellow paint that Greg mixed with each cup of blue paint is (1/2) cup.
B. Greg should add 2 cups of blue paint to each cup of yellow paint.
C. The unit price of per cup of yellow paint is (54/6) = 9 dollars.
