N-5=m
6m-3n=3
6(n-5)-3n=3
6n-30-3n=3
3n=33
n=11
m=6
just use substitution to plug in m in terms of n and solve
Answer:
- WY = 2.2
- m∠W = 63.4°
- m∠Y = 26.6°
Step-by-step explanation:
It is convenient to use the Pythagorean theorem to find the hypotenuse, given the side lengths.
WY² = WX² +XY²
WY² = 2² +1² = 4 +1 = 5 . . . . . fill in the given numbers
WY = √5
WY ≈ 2.2
_____
It is convenient to use the tangent relation to find the angles.
tan(W) = XY/XW = 2/1 = 2
W = arctan(2) ≈ 63.4°
You can do likewise for angle Y, or you can simply find the complement of angle W. (The acute angles in a right triangle are complements of each other.)
Y = 90° -W = 26.6°
The angle measures are ...
Answer:
A. 107 kg
B. 49 kg
Step-by-step explanation:
Answer:
No this is not true.
Step-by-step explanation:
An integer is a whole number and not a fraction.
An integer can be 0, 1, 3, 16, 18, 100, etc.
But an integer is either 0 - infinity.
For 8 * 10^m to equal 8, it has to be a fraction.
So, m can not be a integer. This is wrong.
Hope this helps! :)
Answer:
53,775J
Step-by-step explanation:
KE = ½ mv2
KE = ?
m = 478kg
v = 15m/s
KE = ½ (478kg) (15 m/s)2
KE = ½ (478kg)(225)
KE = 53,775J
