Answer:
39
Step-by-step explanation:
The formula for volume of a prism is length x width x height
If we plug in the given numbers: 4.2 x 7 x 15
We get an answer of 441 cm^3
-2/3x +1/3 +x = 2/5
⇒ 1/3x + 1/3 = 2/5
⇒ 1/3x = 2/5 -1/3
⇒ x/3 = 1/15
⇒ 15x = 3
⇒ x = 3/15
⇒ x = 1/5
Answer: 4/25 ILY <3
Step-by-step explanation:
Given:
The base is a rectangle of dimension 7 cm×6 cm.
The length of each diagonal side = 10 cm
To find the height of MT.
Formula
By Pythagoras theorem we get,

where, h be the hypotenuse
b be the base and
l be the height.
Now, in this diagram,
The perpendicular distance of M from BC = 3 cm
Slant height = 10 cm
Taking, b = 3 and h = 10 we get,

or, 
or, 
or, 
Hence,
The height of MT is 9.5 cm.
