You would divide 530 and 50 to get ur answer of 10.6
Answer:
x = 12/7
Step-by-step explanation:
in order to solve this formula x/4 + x/3 = 1
<u>solutio</u>n
x/4 + x/3 = 1
the first step to do is to take lcm of the left hand side
[3(x) + 4(x)] /12 = 1
[4x +3x]/ 12 = 1
7x/12 = 1
cross multiply
7x/12 = 1
7x = 12 × 1
7x = 12
divide both sides by 7
7x/7 = 12/7
x = 12/7
Answer:
600
Step-by-step explanation:
Percentage required to pass = 40%
Passing marks = 205+35 = 240
Maximum Marks = 240/40 *100
=600

Answer for that: 13.2 = 8.8 - 4.4
Answer:
sqrt(2)/2
Step-by-step explanation:
Given tan(x)=2-cot(x), find sin(x).
Rewrite in terms of sine and cosine:
sin(x)/cos(x)=2-cos(x)/sin(x)
Multiply both sides by cos(x)sin(x):
sin^2(x)=2sin(x)cos(x)-cos^2(x)
Rewrite cos^2(x) using the identity sin^2(x)+cos^2(x)=1:
sin^2(x)=2sin(x)cos(x)-(1-sin^2(x))
Distribute:
sin^2(x)=2sin(x)cos(x)-1+sin^2(x)
Subtracting sin^2(x) on both sides:
0=2sin(x)cos(x)-1
Add 1 on both sides:
1=2sin(x)cos(x)
Use identity sin(2x)=2sin(x)cos(x) to rewrite right:
1=sin(2x)
Since sin(pi/2)=1, then 2x=pi/2.
Dividing both sides by 2 gives x=pi/4.
So sin(pi/4)=sqrt(2)/2
