Answer:
1670.8 cm³
Step-by-step explanation:
Volume of square Pyramid = ⅓*a²*h
h = 15.3 cm
a = 18.1 cm
Plug in the values
Volume of the pyramid = ⅓*18.1²*15.3
Volume = 1670.81 ≈ 1670.8 cm³ (nearest tenth)
I believe the answer is 9
This is because in order to take out a three, There would need to be 2 3's and 9 is 3x3, so the answer is 9.
Answer:
Write a time equation, time = dist/speed
:
go time + return time = total time
d%2F16 + d%2F15 = 7.75 hrs
multiply equation by the least common multiple 240, cncel the denominators:
15d + 16d = 240(7.75)
31d = 1860
d = 1860/31
d = 60 km one way
total dist = 120 km
:
Check this, find the actual time each way
60/16 = 3.75 hrs
60/15 = 4 hrs
-----------------
total time 7.75 hrs
Step-by-step explanation:
Z=95° as opposite angles are equal
The angle next to 120° is 60° as angles on a straight line sum to 180°
This means that y=25° because angles in a triangle sum to 180°
Therefore x=155° as angles on a straight line sum to 180°
Elimination because u could multiply the second equation by -3 which would cancel the x and allow you to solve for y and then everntually x but yea elimination is the best method
