Answer:
4.5 inch
Step-by-step explanation:
Given: A candle is 7 inch tall after burning for 1 hour.
Same candle is 5.5 inch tall after burning for 4 hours.
Lets assume time to burn candle be "x" and height of candle be "y".
Now, finding the rate of changes in height of candle per hour.
Let "m" represent the changes in height of candle per hour.
we know, 
∴ m= 
m= 
Next, forming an equation to know the original height of candle.
using equation; 
We know, A candle is 7 inch tall after burning for 1 hour.
⇒ 
⇒ 
Adding both side by 0.5
⇒
Hence, the original height of candle was 7.5 inches.
Again using the same equation to find the height of candle after burning for 6 hour.
⇒ 
∴ y= 4.5 inches.
Hence, The candle will be 4.5 inches tall after burning for 6 hour.
Answer:
Guy's Graphix = y=7.5x+30
Patty's Printing = y = 5.5x+50
Step-by-step explanation:
Okay so, I am assuming the model is smaller so it would be 0.34m long.
The model has to be 200 times smaller than the actual plane
Divide 68/200 and you get 0.34
Then to check your answer, multiply 0.34 by 200 which is 68 meaning
0.34:68 is equal to 1:200
Assuming the model is bigger (just in case) it would be 13,600m long.
The in this scenario, the model has to be 200 times bigger so it would be 68(200) which is 13,600
Hope this helps
To solve the problem divide the number of elephants by 8 (48 divided by 8 is 6), and then multiply the solution by 5 (6 times 5 is 30).
You can put it in a table like this:
5 10 15 20 25 30 - Monkeys
8 16 24 32 40 48 - Elephants
The answer is B. She sells each orange for $0.50 and the question is asking for the total amount of money she will make by selling a certain amount of oranges. t represents the total so the equation will to equal to t. c is the number of oranges she will sell so c multiplied by $0.50 will give the total amount of money she will make.
