Answer:
The angle is in the second quadrant so only the sine is positive .
Length of the hypotenuse = sqrt (-1^2 + 3^2) = sqrt10
sine = 1/sqrt10 = 0.3162 to 4 dec places
tangent = 1 / -3 = -0.3333 to 4 d p's
cosine = -3/sqrt10 = -0.9487 to 4 d, p's.
Yes, it this somehow related to mathematics? Was this a question?
Answer:
56 lbs
Step-by-step explanation:
Answer:
11/4
Step-by-step explanation:
<em><u>Step 1: Simplify both sides of the equation.</u></em>
12x+3−1=35
12x+3+−1=35
(12x)+(3+−1)=35(Combine Like Terms)
12x+2=35
12x+2=35
<em><u>Step 2: Subtract 2 from both sides.</u></em>
12x+2−2=35−2
12x=33
<em><u>Step 3: Divide both sides by 12.</u></em>
12x / 12 = 33 / 12x =
11 / 4
A) d + q = 27
B) .10d + .25q = 4.35
Multiplying equation A by -.1
-.1d -.1q = -2.7 then adding it to equation B
.1 d + .25q = 4.35 equals
.15q = 1.65
The number of quarters = 11
putting 11 quarters into equation A
d + 11 = 27
dimes = 16
