Formula for Length Change due to Thermal Expansion: The formula for calculating the change in length of a substance due to thermal expansion is ΔL=αLΔT Δ L = α L Δ T where L is the original length of the substance and ΔT is the change in temperature of the substance either in degrees Celsius or in Kelvin.
For comparision of temperature -
Subtract the final temperature from the starting temperature to find the difference. So if something starts at 50 degrees Celsius and finishes at 75 degrees C, then the change in temperature is 75 degrees C – 50 degrees C = 25 degrees C.
Given data
temperature of tuesday = 55 degree
temperature of saturday = 60 degree
Difference between temperature = 60 -55 = 5 degree.
Hence, 5 degree more colder was Tuesday then Saturday.

if 8/9 is multiplied by 3/7 will the product be greater than either of the 2 factors
Answers
If 8/9 is multiplied by 3/7 then the product will not be greater than either of the two factors.
According to the question
on multiplying 8/9 by 3/7 we get
=8/9*3/7
=(8*3)/(9*7)
=24/63
=0.38095 ...(i)
On comparing it with two factors,
8/9 = 0.88888 .....(ii)
and
3/7 = 0.42857 ......(iii)
As we can see that on comparing equation (i) with equation (ii) and
equation (i) with equation (iii) , we get that the product of 8/9 and 3/7 is less than both 8/9 and 3/7 .
Therefore , if 8/9 is multiplied by 3/7 then the product will not be greater than either of the two factors.

How long does it take to ride a bicycle 100 miles at each of the following speeds: 5 mph, 10 mph, 15 mph, 20 mph, 25 mph? What is always true about the product speed x time?
Answers
Answer:
5 mph ⇒ 20 h10 mph ⇒ 10 h15 mph ⇒ 6 2/3 h20 mph ⇒ 5 h25 mph ⇒ 4 hspeed × time = 100 miles
Step-by-step explanation:
The graph shows an inverse relation between speed and time. You want to know what is true about the product of speed and time.
Inversely proportionalTwo quantities are inversely proportional when one is proportional to the inverse of the other. A constant of proportionality will be involved. The relation can be written ...
y = k(1/x)
where x and y are the quantities inversely related, and k is the constant of proportionality.
ApplicationIn the present case, we have a graph of the relation ...
time = distance/speed
where the distance is 100 miles.
Comparing this to the above inverse proportion relation, we see that "distance" is the constant of proportionality (k):
time = (100 miles)/speed
The times at various speeds are ...
5 mph ⇒ 20 h10 mph ⇒ 10 h15 mph ⇒ 6 2/3 h20 mph ⇒ 5 h25 mph ⇒ 4 hMultiplying both sides of this equation by speed, we get ...
speed × time = speed × (100 miles)/speed
speed × time = 100 miles
The product of speed and time is always 100 miles in this scenario.

The factors are 17 and 3.
The given conditions are two factors of the first number, 51 such that their product is 51 and the sum is the second number 20.
let say, the factors are x and y.
therefore, we can write, x.y = 51 ... (1) and x + y = 20 .... (2)
Putting the value of x from equation (2) in equation (1) we get,
(20 - y).y = 51
or, 20y - y² = 51
or, y² - 20y + 51 = 0

Answers
The total cost of the used cell phone in Canadian dollars is C$130.16.
Su Mei should buy the used cell phone because it is cheaper than the new cell phone.
Which phone should Su Mei buy?
The exchange rate is the rate at which one unit of a currency is exchanged for another currency. For example, if the exchange rate of the US dollar and the Canadian dollars is 1.00903. It means that 1 unit of the US dollar would buy 1.00903 of the Canadian dollars.
The first step is to determine the total cost of the used cell phone in US dollar. The total cost would be the sum of the used cell phone and the shipping cost.
Total cost of the used cell phone = $99 + $30 = $129
The next step is to convert the cost of the used cell phone that is priced in the US dollar to Canadian dollars.
129 x 1.00903 = $130.16

How to calculate the probability?A. It should be noted that probability has to do with the chance of a particular thing happening.
In this case, the odds in favor of his character casting a spell are 1/6, therefore the probability of his character casting a spell is 1/6.
B. When a child has a box full of colored building blocks and he chooses one block without looking, the probability of choosing a green block is 7/9, therefore, the odds against choosing a green block will be:
= 1 - P(green block)
= 1 - 7/9

• c. One cannot tell from the information given.
O d. $60,000

Thus the profit of the manufacturer is 240000$ per month
It is given that a product costing 60 cents per unit to produce had been selling at the average rate of 1,200,000 units per month.
After the product was improved, sales increased to an average of 2,000,000 units per month.
It is also given that the new product cost five percent more to produce.
If the manufacturer's selling price in each instance was 75 cents per unit, We are required to find what was the manufacturer's added profit per month with the newer product.
Cost price is the price which the manufacturer pays for each unit
It is given that the cost price of new version is 5 percent more than the previous one.
Thus, the cost price of each unit of product = 60 cents +5 percent of 60 cents = 60+5/100*60=63 cents
It is also given that selling price of each unit is 75 cents
Profit=selling price- cost price
= 75-63= 12 cents
Thus, total profit on selling the 2000000 products= 2000000x12cents
Now we know that 100 cents = 1 dollar
Thus the profit in dollars will be = 2000000*12/100=240000
Thus the profit of the manufacturer is 240000$ per month
