Answer:
u
Step-by-step explanation:
Collect like terms giving u -95+5 less than or equals to 6q then -90 less than or equal 6q. the answer is -15 less than or equals q
Answer:
A rectangle doesn't has a diameter
________________________________
But if you are asking about perimeter.
Step-by-step explanation:
Perimeter = 2(l + b)
l = 9cm
b = 5cm
Perimeter = 2(l + b)
= 2(9 + 5)
= 18 + 10
= 28cm
Answer:
92/100
Step-by-step explanation:
Answer:
-4/5
Step-by-step explanation:
Please use a symbol such as x or Ф to represent an angle; your 0 is too easily confused with zero.
If Angle Ф lies in the second quadrant, and sin Ф=3/5, find cos Ф.
The sine of an angle is the ratio of the length of the opposite side to the length of the hypotenuse: sin Ф = opp / hyp = 3 / 5. Thus the opp side has length 3 and the hyp has length 5. By the Pythagorean Theorem,
the adj side has length √(5² - 3²), or √(25-9), or √16, or ±4. Because the angle is in the 2nd quadrant, choose adj = -4.
Then the cosine of this angle is cos Ф = adj / hyp = -4 / 5
