Answer:
HCFD
Step-by-step explanation:
a² + b² = c² => a² = c² - b² => a = √(c² - b²)
=> the height of the window = √[(the given length of the latter)² - (the distance from the latter to the base of the building, 3.5 meters)²]
A) √(5.5² - 3.5²) ≈ 4.24 => H
B) √(8.8² - 3.5²) ≈ 8.07 => C
C) √(9.3² - 3.5²) ≈ 8.62 => F
D) √(7.9² - 3.5²) ≈ 7.08 => D
Answer:
Step-by-step explanation:
1 hour = 3600 seconds
Distance traveled in 90 seconds = 5 feet
Distance traveled in 1 second = 5/90
Distance traveled in 3600 seconds = 5*3600 / 90
= 5 * 40 = 200 feet
Answer:
p = 5 and q = -3
Step-by-step explanation:
nth term = pn^2 + qn where n is the sequence number.
first term = p + q = 2.....................(1)
2nd term = p(2)^2 + 2n = 14
4p + 2q = 14
2p + q = 7 .......................(2)
Subtract equations (2) -(1) :-
p = 7 - 2 = 5
and q = 2 - 5 = -3
Answer:
D) 31 child tickets and 49 adult tickets
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
To know the scale factor here, just know that 16/4 = 4, and 8/2 = 4 too, so the scale factor is 4.
Just that the respective sides need to have the same ratio.
Note, if it was from B to A, it'd be 1/4.
