In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
7.1 x 10-3
standard form = ?
Step 02:
standard form
7.1 x 10-3 ====> 0,0071
The answer is:
0,0071
Answer:
88%
Step-by-step explanation:
(73+75+84+x)/4=80
x4 to both sides
73+75+84+x=80x4
73+75+84+x=320
232+x=320
x=320-232
x=88
Answer: The answer would be two because one of the lines would be a parabolic line and parabolic lines only have at the most two solutions
Answer:
Step-by-step explanation:
given that a sign in the shape of a right triangle has one leg that is 28(inches) longer than the other leg.
the perimeter is 120 inches
Let the shorter leg have length x inches Then the other leg has length as x+28 inches
The hypotenuse = 120- length of two legs together
= ![92-2x](https://tex.z-dn.net/?f=92-2x)
Since right angled triangle Pythagorean theorem is satisfied
i.e.
![x^2+(x+28)^2 = (92-2x)^2\\2x^2 +56x+784 =8464-368x+4x^2 \\2x^2-424x-7660=0\\x^2-212x-3830 =0\\](https://tex.z-dn.net/?f=x%5E2%2B%28x%2B28%29%5E2%20%3D%20%2892-2x%29%5E2%5C%5C2x%5E2%20%2B56x%2B784%20%3D8464-368x%2B4x%5E2%20%5C%5C2x%5E2-424x-7660%3D0%5C%5Cx%5E2-212x-3830%20%3D0%5C%5C)
We get x as negative or 228.744
this is not possible as perimeter is 120 inches only
Hence no solution
