90 and 91 are relatively prime, the way they can be relatively prime is to have no factors in common-
90- 2x3x3x5
91- 7x13
Answer:
$262.50
Step-by-step explanation:
7 Months is approximately 30 weeks.
25 x 30 = $750
10% = $75
5% = $37.50
60% = (75x6) = $450
$450 + $37.50 = $487.50
$750 - $487.50 = $262.50
Answer:
see explanation
Step-by-step explanation:
The missing angle is 45°, thus the right triangle is isosceles.
Then the 2 sides y and 7 are congruent.
Hence y = 7
Using Pythagoras' identity to calculate x
x² = 7² + 7² = 49 + 49 = 98
Take the square root of both sides
x = = = 7 ≈ 10
Answer:
4ti + 5tj + k
Step-by-step explanation:
Initial condition V(0) = k
at t = 0
general equation for v(t )
V(0) = 0i + 0j + c = k
when we compare V(0) and solve for c , c = k
back to general equation
V(t) = 4ti + 5tj + c = 4ti + 5tj + k
