Step-by-step explanation:
[tex]\frac{9.00 - 7.50}{7.50} \times 100\% = 20\% \: increase[/tex][tex] \frac{6.50 - 5.00}{5.00} \times 100\% = 30\% \: increase[/tex][tex] \frac{4.50 - 2.00}{2.00} \times 100\% = 125\% \: increase[/tex][tex] \frac{2.00 - 2.50}{2.50} \times 100\% = - 20\%[/tex]In order to get the increase or decrease, we need to get the difference of the two prices first. Then, pick a "reference year".
From the calculations, notice how I made the earlier years as my reference points. If the calculations produced positive results, therefore, it has increased. If it produced a negative results, from the reference year's price, it has decreased in price.

Find an equation in point-slope for the line having the slope m m = - 6 and containing the point (8,6)
Answers
Answer:
y-6 = -6(x-8)
Step-by-step explanation:
Here, we want to get the equation of the line in point-slope form
The point slope form is;
y-y1 = m(x-x1)
(x1,y1) represents the slope
We have this as ;
y-6 = -6(x-8)

A loaf of bread is cut into slices.
1. If each slice is 1/2 of a loaf, how many slices are there?
:
2. If each slice is 1/5 of a loaf, how many slices are there?
:
3. What happens to the number of slices as each slice gets smaller?
:
Answers
1. There would be 2 slices as the denominator is 2.
2. There would be 5 slices as the denominator is 5.
3. As each slice gets smaller, the denominator gets bigger, because the bigger the denominator is, the more pieces it needs to make a whole.
Hope this helps :)
There are 2 pieces if each slice is 1/2 of a loaf, and 5 pieces if each slice is 1/5 of a loaf, and the total number of pieces get increases if each slice gets smaller.
What are fractions on number lines?When fractions are represented on a number line, we can plot them on a number line just like we can with whole numbers and integers. Parts of a whole are represented by fractions. In order to depict fractions on a number line, equal pieces of a whole are divided.
Given A loaf of bread is cut into slices.
1. If each slice is 1/2 of a loaf, how many slices are there,
here slices are 1/2 of the loaf so the loaf is divided into two equal parts,
1/2 + 1/2 = 1
2. If each slice is 1/5 of a loaf, how many slices are there,
here loaf has 5 equal parts,
1/5 + 1/5 + 1/5 +1/5 + 1/5 = 1 loaf
3. What happens to the number of slices as each slice gets smaller?
the value of the denominator in fraction goes on increasing and since the value is increasing the number of slices also gets increases.
Hence there are 2 pieces for 1/2 of the loaf,
5 pieces for 1/5 of the loaf,
and the number of slices increases when each slice gets smaller.

Step-by-step explanation:
Note that 0.8 is a factor of the three coefficients -0.8, -6.4 and 7.2. Thus,
-0.8x2 - 6.4x + 7.2 = 0.8(-1x^2 - 8x + 9), or, equivalently,
= -0.8(x^2 + 8x - 9), which factors further as follows:

Answers
Answer:
E, F, B, and C
Step-by-step explanation:
Im just learning about these kind of things and this is a challenging question not going to lie.
I chose B because expanding and building more factories is apart of economics. You need more land to expand your business, but this will also affect the economy.
C seems like a good answer also because writing about economic trends is an important thing in economics. This also helps others learn out the economy and what not to do and what to do to help make our environment a better place.
I chose E because starting a business is apart of economics. A lot of business are apart of economic systems and help money come into our economy.
F is a good answer for me because the U.S government has been apart of America's economic system for a long time just like they are involved with everything else. The government is a big help and a big part of our economy, especially for america.

We can find the magnitude of the big rectangle. We will need to find the total length and total breadth of the big rectangle
Then we remove the area of the four squared cut out from the big rectangle.
Total length of the rectangle is 5+1+1=7m
Then the length of the breath of the rectangle is 2+1+1=4m
So area of rectangle is given as length × breadth
Area= l×b
Area=7×4=28m²
Area of the big rectangle is 28m²
Then the squared is made of dimension 1m by 1m
Area of a square is s²
Then, a=1m
Area of the square= 1²=1m²
There are four squared side
Then, the total area of the four squared is 4×1=4m²
Then the required area is
Area=Total area - area of four squared side
Area=28m²-4m²
Area =24m²
Area of the figure is 24m²
The correct option is A.

Jane and 3 friends decided to split the cost of a pizza evenly. The total cost was $25.48. How much does each friend have to pay?
Answers
Answer:
$6.37
Step-by-step explanation:
Jane and 3 friends = Jane + another 3 people
= 4 people in total
Total Cost of pizza = $25.48
If 4 people split $25.48 evenly,
Amount each friend has to pay = Total Cost of pizza/Total number of people
= $25.48/4
= $6.37 per friend
Each friend has to pay $6.37 each if $25.48 is splitted evenly amongst them

Answers
Answer:
There are 37 marbles.
Probability = (# favorable outcomes) / (# total outcomes)
P (r or g) = 25/37
3) 25/37
Step-by-step explanation:
The probability of red or green marbles is 0.676
How to determine the probability?The given parameters are:
8 red marbles, 12 blue marbles, and 17 green marbles
The number of red or green marbles is:
Red or Green = 8 + 17
Evaluate
Red or Green = 25
The probability of red or green marbles is:
P = 25/(8 + 12 + 17)
Evaluate
P = 0.676
Hence, the probability of red or green marbles is 0.676
