How to solve the problem in different ways

Fiona purchased 400 m2 of plastic sheeting and needs to cut it into rectangles of area 500 cm2. This can be done with no waste.

Answer:

8000

Step-by-step explanation:

The number will be ...

(400 m^2)/(500 cm^2) = 0.8 (m/cm)^2 = 0.8 ((100 cm)/(1 cm))^2

= 0.8·100^2 = 8000

Fiona can cut 8000 rectangles from the plastic sheeting she bought.

Carter randomly selected some red and yellow clothing items at a store and recorded their prices. The tables below show the data

sukhopar [10]

Answer:

You have to compare if true some of the statements.

Most of these type questions would be compare the first three data

1. Prices of red to yellow mean we need to add them all up to begin with. 10 x £29.95 + 5 x 35.99 etc. = 15 items or add one zero (x10) to 29.95 and for 35.99 we add zero (x10) then divide by 2 ie) 359.9/2 = 360/2-0.2 = 180 - 0.2 = $179.98

2. Higher and lower comparisments we just take away from total.

3. The difference or how much more something is we subtract from the full total.

This would be a 4 way thought process below;

1. Prices in $ could mean groups, mean high or low we need to count how many items and add up all the prices to find the mean by adding them together.

2. Colour's could mean more red than yellow over a certain price or under a certain price.

3. Colour could also mean how many as a combined data were higher or lower than a certain price. ie) Higher than $29.99 would mean all the data set at $30.00 more. LEss would mean lower than $29.98

4. Mean and fx would be all the prices added together + all the items togather for the fx we multiply the individual groups and create a new box. We then multiple it to the other totals. This can also help establish or be compared to the percentage for advanced data tables.

I'll do problem 1 to get you started.

The answer to problem 1 is <u>3400 miles</u>

============================================================

Explanation for problem 1:

We're asked to find the perimeter, which is the total distance around the exterior or outside. In other words, we need to add up the four side lengths of this quadrilateral.

We'll need the distance formula to find the lengths of the slanted sides AB and BC

----------------------------------------

Let's first find the length of segment AB

A = (x1,y1) = (0,0)

B = (x2,y2) = (400,300)

d = Length of AB

$d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(0-400)^2 + (0-300)^2}\\\\d = \sqrt{(-400)^2 + (-300)^2}\\\\d = \sqrt{160000 + 90000}\\\\d = \sqrt{250000}\\\\d = 500\\\\$

The distance from A to B is 500 miles. This is the same as saying segment AB is 500 miles long.

----------------------------------------

Now find the length of segment BC

B = (x1,y1) = (400,300)

C = (x2,y2) = (-800,800)

d = length of BC

$d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(400-(-800))^2 + (300-800)^2}\\\\d = \sqrt{(400+800)^2 + (300-800)^2}\\\\d = \sqrt{(1200)^2 + (-500)^2}\\\\d = \sqrt{1440000 + 250000}\\\\d = \sqrt{1690000}\\\\d = 1300\\\\$

----------------------------------------

The length of CD is fairly easy to find without needing the distance formula. This is because it is a vertical line. We subtract the y coordinates of C and D to get 800-0 = 800. So CD is 800 miles long.

Segment DA is a similar story. But we subtract the x coordinates. This only works for horizontal lines. DA is 800 miles long because |-800-0| = 800. Absolute value is used to make sure the distance is never negative.

----------------------------------------

To summarize everything so far, we found these four side lengths

AB = 500
BC = 1300
CD = 800
DA = 800

The perimeter is going to be the sum of those four sides, leading to...

perimeter = sum of sides

perimeter = AB+BC+CD+DA

perimeter = 500+1300+800+800

perimeter = 3400 miles

This is the total distance traveled if you started at city A, went to B, then to C, then to D, and then finally went back to A.
