<span>the formula d = rt
</span><span>
r = d/t (</span>c. d over t = r<span>)
</span>t = d/r (a. d over r = t)
d = rt (<span>d. d over rt = 1)

so answer
</span>b. r = dt ......not equivalent to the formula d = rt
Sin A = opposite / hypotenuse
If angle A is in the first quadrant, that means both x and y coordinate are positive.
Now you can draw triangle. Since sinA = 1/3, opposite side may be 1, so then hypotenuse side must be 3.
Now you can use Pythagorean Theorem to solve for the length of adjacent side:
a² + b² = c²
1 + b² = 9
b² = 8
b = 2√2
So adjacent side is 2√2.
So now we can solve for cosA:
cosA = adjacent / hypotenuse = 2√2 / 3
Final answer: 2√2 / 3
Answer:
x=1/6 or 1.16 (6 repeating) or x=6^-1
Step-by-step explanation:
y=6x-1
substitute y =0
0=6x-1
Move the variable to the left
-6x =-1
Divide on both dies

Answer:
5 gallons
Step-by-step explanation:
3/4 + 6/8 + 20/8 + 1
6/8 + 6/8 + 20/8 + 8/8
40/8 = 5 gallons
