Find the volume of the figure

Mathematics
1 answer:
mote1985 [20]3 years ago
4 0

Answer:

<h2>V = 1920 cm³</h2>

Step-by-step explanation:

We have two rectangular prisms:

14cm × 8cm × 10cm and 8cm × 10cm × 10cm

The formula of a volume of a rectangular prism l × w × h:

V = lwh

Substitute:

V₁ = (14)(8)(10)=1120 cm³

V₂ = (8)(10)(10) = 800 cm³

The volume of the figure:

V = V₁ + V₂ → V = 1120 + 800 = 1920 cm³

Which ordered pair can be plotted together with these four points, so that the resulting graph still represents a function?
MrRissso [65]

Answer:

B.(-1,2)

Step-by-step explanation:

In a function, there can not be two different values of y corresponding to the same value of x.

See the graph attached.

Here, the points on the graph are (1,2), (2,-3), (-2,-2) and (-3,1).

If we consider point (-2,2) then there will be two points corresponding to the same x value i.e. (-2,-2) and (-2,2).

Similarly, if we consider the point (2,-2) or (2.-1) then also there becomes more than one values of y for a single value of x i.e. x = 2.

So, if we consider the ordered pair (-1,2) then only the graph still represents a function. (Answer)

A motor boat travels 60 miles down a river in 3 hours but takes 5 hours to return upstream. Find the rate of the boat in still w
prohojiy [21]

Step-by-step explanation:

Given that,

A motor boat travels 60 miles down a river in 3 hours but takes 5 hours to return upstream,

We know that,

Speed = distance/time

The rate while moving downstream=\dfrac{60}{3}=20\ mph

The rate while moving upstream =\dfrac{60}{5}=12\ mph

The rate of the boat in still water is the average of these:

v_s=\dfrac{20+12}{2}=16\ mph

The rate of the current is the difference between the boat speed and actual speed = 16 mph - 12 mph = 4 mph

Hence, this is the required solution.
