Answer:
21.01 cubic metres
Step-by-step explanation:
We have to find the value of 1 cubic foot and then convert to cubic metre.
1 foot = 0.3048 m
1 cubic foot =
= 0.02832 cubic metre
A volume of 742 cubic foot will therefore be:
742 * 0.02832 = 21.01 cubic metres
The volume in cubic metres is 21.01 cubic metres
<span>7/10x-1/5=4 should be written as (7/10)x - 1/5 + 4
or as 7x/10 - 1/5 = 4.
Multiply all 3 terms of the latter equation by 10 to eliminate fractions:
7x - 2 = 40
Then 7x =42, and x = 6.</span>
Given that N is the incenter of △ABC, NS = 4.
<h3>What is the Incenter of a Triangle?</h3>
- The incenter of a triangle is the point of concurrency of the three angle bisectors of a triangle.
- The perpendicular distances from each sides of the triangle to the incenter are equal.
Given the image where:
NQ = 2x
NR = 3x − 2
NQ = NR = NS (equidistant from the incenter)
Thus:
2x = 3x - 2
2x - 3x = -2
-x = -2
x = 2
NQ = NS = 2x
NS = 2(2)
NS = 4
Therefore, given that N is the incenter of △ABC, NS = 4.

Answer:
Step-by-step explanation
The length of the left sloping line
= √ (5^2 + 7^2) = √74.
The right sloping line
= √(5^2 + 5^2) = √50.
So the perimeter:
= √74 + √50 + 2 + 2 * 4 + 14
= 39.67 to nearest hundreth.
Area = 1/2 * 5 * 7 + 2*5 + 1/2 * 5 * 5 + 4*14
= 96.
