Answer:
253.5 ft³
Step-by-step explanation:
Volume of a pyramid = 
× base area × height
Volume of a prism = base area × height
Volume of the pyramid
= × (6×6.5÷2) × 9
= × 19.5 × 9
= 58.5 ft³
Volume of the prism
= (6×6.5÷2) × 10
= 195 ft³
Volume of the solid
= 58.5 + 195
= 253.5 ft³
<h3>
Answer: 43 km per hour</h3>
==================================================
Work Shown:
total distance = 43+40+46 = 129 km
total time = 1+1+1 = 3 hours
average speed = (total distance)/(total time)
average speed = (129 km)/(3 hrs)
average speed = (129/3) (km/hr)
average speed = 43 km per hour
Answer:
3/16
Step-by-step explanation:
Step-by-step explanation:
DC is equal to 180°, so subtract 105 from 180.
180-105=75
180 is the total of the the angles when added together.
67°+75°=142
180-142=38
x=38
