Answer:
Step-by-step explanation:
1. Write an expression to show how to calculate the number of buses needed. Make sure to include parenthesis to show what should be done first since order of operations is important.
(9*25)+4+(2*4)=237 (total number of people going to the museum
Each bus,excluding the driver,holds 44 people
237/44 = 5.3863636363.......
2. How many buses will be needed?
6 buses are needed
3. Why must the answer to the problem be a whole number?
Buses cannot be divided in fractions It should be or 5 buse or 6
But 5 buses are not enough
4. Why shouldn't you round the answer the usual way?
Even when rounded it is still a decimal and buses need to be counted by whole number
5. Can your answer be classified as a rational number? Explain why or why not.
6 is a rational number (whole number)
5.38636363.......is rational ( repeating decimal
Answer: The length is 12 inches while the height is 5 inches
Step-by-step explanation: It the Television has a diagonal of 13 inches, and a height of H inches, then the length would be (H + 7) inches. It’s length is 7 inches more than the height. At this point we can draw up a right angled triangle with the hypotenuse as 13 (diagonal side) and the other two sides as H and (H + 7)
Then we can apply the Pythagoras theorem which states that
AC^2 = AB^2 + BC^2
(Where AC is the hypotenuse and AB and BC are the two other sides)
Hence,
13^2 = H^2 + (H + 7)^2
169 = H^2 + (H^2 + 14H + 49)
169 = 2H^2 + 14H + 49
By collecting like terms we now have
169 - 49 = 2H^2 + 14H
120 = 2H^2 + 14H
By re-arranging all terms on one side of the equation, we arrive at
2H^2 + 14H - 120 = 0
Divide all sides by 2
H^2 + 7H - 60 = 0
To solve the quadratic equation, we now factorize and we have,
H^2 + 12H - 5H - 60 = 0
(H + 12) (H - 5) = 0
Therefore
Either H + 12 = 0 OR
H - 5 = 0
Hence, Either H = -12 or H = 5
The dimension can not be a negative value so we shall take h equals 5.
Having calculated the height of the television as 5 inches, the length which was given as H + 7 can now be calculated as
Length = H + 7
Length = 5 + 7
Length = 12
Therefore, the length of the Television is 12 inches and the height is 5 inches
Area=(base x height)/2
base=5.8 cm
height=2.4 cm
Area=(5.8 cm * 2.4 cm) / 2=6.96 cm²
The answer is A 6.96
