Answer:
x = 2.4/20= 0.12
Step-by-step explanation:
Multiply both sides by 4 to eliminate the fraction 1/4:
1 20
--- = ------
x 2.4
Next, we cross-multiply. This eliminates the fractions:
20x = 2.4
Dividing both sides by 20 results in an equation for x: x = 2.4/20= 0.12
Answer:
m = 12.728 or 18/root (2)/2, n = 9
Step-by-step explanation:
To find m, we can use sin(45) and cos(45).
Since sin(45) = root (2)/2 and this equals 9/m.
We set the equation root (2)/2 = 9/m and solve for m.
9 divided by root (2)/2 would give us 18/root (2), or 12.728.
m is 12.728.
Same process for n but we are using cosine this time.
cos(45) = root (2)/2 and this equals n/12.728.
Solving for n would give us root (2)/2 times 12.728.
This gives us that n is 9.
The answer is W. (Please make me Brainliest.) Hope this helps!
