Answer:
30 cubic feet
Step-by-step explanation:
Here we are given the volume of rectangular pyramid as 90 cubic feet as we are required to find the volume of rectangular prism.
For that we need to use the theorem which says that
the volume prism is always one third of the volume of the pyramid . Whether it is rectangular of triangular base. Hence in this case also the volume of the rectangular prism will be one third of the volume of the rectangular pyramid.
Volume of Rectangular prism =
* Volume of rectangular pyramid
=
* 90
= 30
The first is an irrational number and the rest are rational
Any number that can be reduced or written as a fraction is a rational number

Answer:
x=2
Step-by-step explanation:
The diagram is attached below
TU=TW+WU
x+7=3+WU
WU=x+7-3
WU=x+4
To determine the value of x, we apply the theorem of intersecting chords.
TW X WU = CW X WV

Answer:
14C + 70B
Step-by-step explanation:
Let us represent:
The number of cans = C
The number of bottles = B
Her truck is filled with cans that weigh 14 ounces each and bottles that weigh 70 ounces each. There is a combined total of 880 cans and bottles in her truck.
The expression for the combined total weight (in ounces) of the cans and bottles in her truck is given as
Total weight in out = 14 × C + 70 × B
= 14C + 70B
When:
C + B = 880
