Jack said that if you take a number and multiply it by a fraction,the product will always be smaller than what you started with.
1 answer:
Answer:
No
If the fraction is an improper fraction, the product would be higher
if the numerator of the fraction is smaller than the denominator, the product would be lower
2 x 3/4 = 3/2 = 1 1/2
2 x 4/3 = 8/3 = 2 2/3
Step-by-step explanation:
an improper fraction is a fraction in which the numerator is greater than the denominator
The numerator is the number above. While the denominator is the number below
an example of a fraction =
4 is the numerator while 5 is the denominator

Answer: 42.21 km
Step-by-step explanation:
We can solve this using trigonometry, since we have the following data:
is the the angle of elevation
is the horizontal distance between the plane and the radar station
is the hypotenuse of the right triangle formed between the radar station and the airplane
Now, the trigonometric function that will be used is <u>cosine</u>:
because
is the adjacent side of the right triangle

3 times a number minus 2 equals 13
3 × n - 2 = 13
3n - 2 = 13
take 2 to the other side
3n - 2 + (2) = 13 + (2)
3n = 15
Divide by 3 on either sides to isolate n
= 
3 and 3 cancels out
n = 5
check:
3 times 5 minus 2 equals 13
3 × 5 - 2 = 13
15 - 2 = 13
13 = 13
The number is 5
3 times a number minus 2 equals 13
3 × n - 2 = 13
3n - 2 = 13
take 2 to the other side
3n - 2 + (2) = 13 + (2)
3n = 15
Divide by 3 on either sides to isolate n
3 and 3 cancels out
n = 5
check:
3 times 5 minus 2 equals 13
3 × 5 - 2 = 13
15 - 2 = 13
13 = 13
The number is 5
