Answer:
36(5)^-2.
Step-by-step explanation:
5^-2 * 9
= 9(5)^-2
2^4 * 4 ^ -3
= 2^4 + (2^2)^-3
= 2^4 * 2^-6
= 2^-2
So the answer is
9(5^)-2 / 2^-2
= 9(5)^-2 * 2^2
= 4*9(5)^-2
= 36(5)^-2.
(8r⁶s³ - 9r⁵s⁴ + 3r⁴s⁵) - (2r⁴s⁵ - 5r³s⁶ - 4r⁵s⁴)
8r⁶s³ - 9r⁵s⁴ + 4r⁵s⁴ + 3r⁴s⁵ - 2r⁴s⁵ - 5r³s⁶
8s⁶r³ - 5r⁵s⁴ + r⁴s⁵ - 5r³s⁶
Answer:
open circle
Step-by-step explanation:
open circle is greater than < and less than > and closed circle are the ones with the line under the symbol
Height of each floor = 5 meters
time to travel from the first floor to 68th floor = ?
Speed of elevator = 7.5m/s
While an elevator travels from 1st floor to 68th floor, we will multiply the height of floor with 67 to get the distance covered by the elevator form 1st floor to 68th floor, the height of 68th floor will not be counted in the distance because an elevator reaches the 68th floor not covered the height of that floor.
Distance = 5 x 67 = 335m
Now calculate the time by using the formula;
time = distance / speed
= 335m / 7.5m/s
= 44.667 seconds
Thus, an elevator will take 44.667 seconds to reach 68th floor.
M is smaller than km
1000m=1km
so divide by 1000
basically move decimal 3 places to left
put zero in front
0.0548km
