\bf \begin{array}{ccllll}
total\ weight&muscle\ weight\\
-----&-----\\
140&60\\
x&90
\end{array}\implies \cfrac{140}{x}=\cfrac{60}{90}

solve for "x".

A floor is made up of 20 triangular tiles, each with sides 40 cm, 24 cm and 32 cm. Find the cost of polishing the floor at the r
pochemuha

Answer:

15360\,\,rupees

Step-by-step explanation:

Let sides of the triangle be a,b,c

a=40\,,\,b=24\,,\,c=32

Semi-perimeter (s) = \frac{a+b+c}{2}

=\frac{40+24+32}{2}\\ =\frac{96}{2}\\=48

Area of one tile =\sqrt{s(s-a)(s-b)(s-c)}

=\sqrt{48(48-40)(48-24)(48-32)}\\ =\sqrt{48(8)(24)(16)}\\ =\sqrt{147456} \\=384\,\,cm^2

So,

Area of 20 tiles =20(384)=7680\,\,cm^2

Cost of polishing the floor at the rate of 2 rupees per sq.cm = 7680(2)=15360\,\,rupees

Convert the angle in degrees to radians. Express your answer as a multiple of π.
Elena L [17]
Converting 25 degrees to radians:

180° = π radians.

1° =  π/180  radians.

25° =  (π/180  radians) * 25

       =    (25/180) * π  radians.

Leaving the answer in terms of π,  25/180 = 5/36

=    (25/180) * π  radians = (5/36)π  radians  or ≈ 0.1389π radians.


Therefore 25° = (5/36)π  radians  or ≈ 0.1389π radians

I hope this explains it.

I think why you did not get it was because you did not leave your answer in terms of π or as a multiple of π, so as a multiple of π our answer is:

= (5/36)π  radians  or ≈ 0.1389π radians

Correct answer gets brainliest and 5 stars
Serggg [28]

Answer:

A is false

Step-by-step explanation:

notice how in both diagrams, there are 4 triangles with lengths a, b, c, but in each diagram the triangles are just rotated and positioned differently. if there are the same amount of triangles in both diagrams, and the have equal lengths then the area of the remaining figure, should both match up.

basically the area of the big square in Step 2, is equal to both of the shaded squares, combined area, in Step 1.

Which number satisfies the inequality 9h + 15 > 55?
zalisa [80]

When you say "Which number ...", I expect to see a list of choices at the
end of the question, and I get very upset when there's nothing there.

                                            9h + 15 > 55

Subtract  15  from each side:          9h > 40

Divide each side by  9 :                  <em>  h > 40/9</em>

Any number greater than (4 and 4/9) satisfies the inequality.
