Answer:
The answer to this would be B.
Step-by-step explanation:
When finding the volume of a three-dimensional object you want to use the formula, (Length) x (Height) x (Width) = (Volume)
In this case, 6 cm is your height
3 cm is your length,
and 2 3/4 cm is your width.
When you plug in those numbers, the only equation that matches is B. 6x3x2 3/4.
Hope this helped!

Answer:
44 words
Step-by-step explanation:
Step one:
given data
The dimension is
7cm long and = 0.07mm
5mm in diameter
radius= 2.5mm
The volume = πr^2h
Volume= 3.142*2.5^2*0.07
Volume= 3.142*6.25*0.07
volume= 1.4 mm^3
If 1.4 mm^3 will write 310 words on an average
1/5(0.2mm^3) liter will write x
cross multiply we have
x= 0.2*310/1.4
x=62/1.4
x=44 words
Answer:
A geodesic dome is composed of two different types of triangular panels. One of these is an isosceles triangle. In one geodesic dome, the measure of hte third angle is 58.5 degrees more than the measure of either of the two angles. Find the measure of the three angles.
Step-by-step explanation:
d = 36 mi the distance traveled in one direction
t1 = 1.5 hr the time of the trip upstream
t2 = 1 hr the time of the trip downstream
s = the speed of the stream
v = the speed of the boat in still water
the speed of the boat upstream is: v - s
the speed of the boat downstream is: v + s
traveling upstream
(v - s)*t1 = d
(v - s)*1.5 = 36
traveling downstream
(v + s)*t2 = d
(v + s)*1 = 36
by solving the system of equations
(v - s)*1.5 = 36
v + s = 36
we find
s = 6 mph
v = 30 mph
