Answer:
It's the last answer choice.
Step-by-step explanation:
We need to solve for b, so divide each side by H, and then multiply each side by 2 to get rid of the 1/2
2.451, 2.5, 2 5/8
this is the right answer

If the number is x
the expression is -
x/2 - 7= 1 + 5/10
Answer: 6 movies
Step-by-step explanation:
$20+$1.50= $21.50
$3.50x6= $21
The angle between two vectors is given by:
cos (x) = (v1.v2) / (lv1l * lv2l)
We have then:
v1.v2 = (2, -5). (4, -3)
v1.v2 = (2 * 4) + (-5 * (- 3))
v1.v2 = 8 + 15
v1.v2 = 23
We look for the vector module:
lv1l = root ((2) ^ 2 + (-5) ^ 2)
lv1l = 5.385164807
lv2l = root ((4) ^ 2 + (-3) ^ 2)
lv2l = 5
Substituting values:
cos (x) = (23) / ((5.385164807) * (5))
x = acos ((23) / ((5.385164807) * (5)))
x = 31.33 degrees
Answer:
The angle between the two vectors is:
x = 31.33 degrees
