Answer:
48
Step-by-step explanation:
There are 3 one-digit numbers: 3, 5, 7.
There are 15 two-digit numbers: 33, 35, 37, 43, 45, 47, 53, 55, 57, 63, 65, 67, 73, 75, 77.
There are 30 3-digit numbers, from 333 to 477. The leading digit must be 3 or 4; the trailing digit must be 3, 5, or 7; and the middle digit can be any of the 5 digits, for a total of 2×5×3 = 30 possible 3-digit numbers. (That is, 300 or 400 can be added to any of the 15 2-digit numbers.)
Using the given digits, 3+15+30 = 48 odd numbers less than 500 can be written.
Answer:
No there is no solution
Step-by-step explanation:
X cannot be found no matter how you try to solve the simultaneous equation so therefore y can also not be found.

Answer:
Step-by-step explanation:
The answer is w = 3, in other words A, I took the test.
The object reaches the lowest height at 5 seconds
<h3>How to determine the time?</h3>
The function is given as:
f(t) = -2t² +22t + 6
Differentiate the function
f'(t) = -4t +22
Set to 0
-4t +22 = 0
Subtract 22 from both sides
-4t = -22
Divide both sides by -4
t = 5.5
Remove decimal points
t = 5
Hence, the object reaches the lowest height at 5 seconds
