Answer: Calendar

Step-by-step explanation:

Basically, the Mayan Calendar was going through cycles, and December 21 2012 was the end of a cycle. It was close to the 13th Bak’tun, but instead of moving towards the next Bak’tun and so on, the Mayan calendar actually reset itself back to 0. But the Mayans did not predict the end of the world, we decided to interpret the calendar that way.

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.

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.

Answer:

The independent variable (x) represents the members to go paintballing.

The dependent variable (y) represents the total cost.

Step-by-step explanation:

The y is always dependent on the x. The number of people attending affects the total cost of the trip. The more people attend, the more it costs.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept. y=2x-4 is the slope-intercept form of the line with a slope of 2 and a y-intercept of -4.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope intercept form of a line is y=mx+b,

where m is slope and b is the y intercept.

slope-intercept form of the line with a slope of 2 and a y intercept of -4.

m=2 and b=-4

Substitute the m and b value in slope intercept form.

y=2x-4.

Hence y=2x-4 is the slope-intercept form of the line with a slope of 2 and a y-intercept of -4.

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:

Answer:

C.

Step-by-step explanation:

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

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

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°
