B is also correct answer for this question.
Answer:
x =
, y = 2
Step-by-step explanation:
using the tangent ratio and the exact value tan45° = 1 , then
tan45° =
=
= 1 , then
x = 
----------------------------------
using the cosine ratio in the right triangle and the exact value
cos45° =
, then
cos45° =
=
=
( cross- multiply )
y =
×
=
= 2
Answer:
c
Step-by-step explanation:
3⁶ * 4² * 12 = 3⁶ * 4² * 4*3 = 3⁷ * 4³
3³ * 4 * 5
GCF= 3³ * 4
Only common factor with minimum power
Answer:
6 gallons of gas
Step-by-step explanation:
20.00 - 2.12 = 17.88
17.88 divided by 2.98 equals 6
|x-6| < 1 + 10 (move 10 to the right side)
|x-6| < 11
1)x-6 < 11 (here x >= 6)
2)-x+6 < 11 (here x < 6)
1)x<17
2)x>-5
so we get -5 < x < 17
the answer: (-5; 17)
