Answer:
5 batch of cookies.
Step-by-step explanation:
A batch of cookie requires cups of sugar.
Ty has cups of sugar.
He can make the total number of batches = ÷
= ÷
= ×
=
= 5 batches of cookies
Ty can make 5 batches of cookies.
To determine the total number of people surveyed when given the number who preferred swimming and the percentage they represent, you set up an equation based on the percentage and then solve for the total. With this data, 40 people were surveyed.
The question pertains to the mathematical concept of percentages. You mention that 27.5 percent of the surveyed population favored swimming and this equaled to 11 people. To calculate the total number of people surveyed, we let the total number be 'x'. Therefore, the mathematical equation, based on the provided data, becomes 27.5% of 'x' = 11. In mathematical terms, it can be written as 0.275x = 11. For finding 'x', divide both sides of the equation by 0.275. Thus 'x' = 11 / 0.275 = 40. Therefore, based on the given percentages and data, it's inferred that a total of 40 people were surveyed.

1 ) D
2 ) D
Step-by-step explanation:
The general form of the straight line is given by y=mx+c, where m is the slope and c is y-intercept.
1 ) According to the graph, we get the co-ordinates (0,-1) and (-1,0).
Using these so-ordinates, we will find the equation of the line.
i.e. Slope
i.e.
i.e. m = -1
Now, substituting m and (0,-1) in general form, we get c = -1.
So, the equation of this straight line is y = -x-1.
We will now use 'Zero Test' i.e. substitute (0,0) in the required equation and since the given regions are away from the origin, this pair of points will not satisfy the equation.
So, we get y < -x-1 and as the region is given to less than x= -3.
Hence, option D is correct.
2) Now, according to the second graph, we get the points (0,-2), (-2,0) and (0,1), (-1,-1) for two lines respectively.
Solving as in 1) we get that the equations of the lines are given by x+y = -2 and y = 2x+1 respectively.
Again using 'Zero Test', we see that these pair of points does not satisfy the equations.
So, we get x+y < -2 and y > 2x+1.
Hence, option D is correct.
Answer: C and B
Step-by-step explanation:
The required model is attached in the image and the division of 3/4 by 3 /12 is 3.
Given that,
To draw the model to represent 3/4 divided by 3/12.
In mathematics, it deals with numbers of operations according to the statements.
Model hs been attached below for the given problem of division,
= 3 * 4 / 3 * 12
For a rectangle space, drawing 4 column and 12 raws,
Now for 3 / 4 3 of the 4 column to be filled by red, for 3 / 12 every 3 cells in the row have been filled by red.
Calculating number of cells in 3 / 4 = 36
calculating number of cells in 3 / 12 = 12
Now ratio of the cells = 36 / 12 = 3
Thus, the required model is attached in the image and the division of 3/4 by 3 /12 is 3.

The answer you are looking for is 1/3.
First, you must look at the denominators of each fraction, to see if you can simply divide straight across. In this case, you cannot, which means you must multiply by the reciprocal or "flipped" number. Generally when you multiply by the reciprocal, you flip the number with the smaller denominator to multiply.
So, you have 4/3 * 3/12. You then multiply straight across (4 * 3)/(3 * 12), to get an answer of 12/36, which simplified (divided by 3/3) gives you a final answer of 1/3.
I hope this helps!
