I'm assuming your teacher wants you to calculate the speed
1/2 = 0.5
3 & 1/2 = 3 + 1/2 = 3 + 0.5 = 3.5
If a plane flies 840 miles in 3.5 hours, then,
speed = distance/time
speed = (840 mi)/(3.5 hr)
speed = (840/3.5) mph
speed = 240 mph
<h3>Answer: 240 mph</h3>
Answer:
ABD = 40, CD = 143, X = 43.5, AB = 140, BC = 126
Sorry I'm in a hurry right now so I can't give explanations but I hope this helps!
Volume of the original cube is a³ .
That's (a · a · a) .
If you decrease the sides to 20% of their original size,
then the new volume is (0.2a · 0.2a × 0.2a).
That's 0.008a³ or (0.2a)³ .
Take your choice. I can't decide which one is simpler.
The answer
3. measure of DEA is 43°
proof: 90° +47° + mDEA= 180°, so mDEA= 43°

Answer:
G 45
Step-by-step explanation:
If Z is the circumcenter, it is equidistant from the vertices T, U, V. That is, ΔZUV is an isosceles triangle and Y is the midpoint of UV.
If Y is the midpoint of UV, then UY = VY = 22.5, and UV = UY +VY = 45.
The length of UV is 45.
