Answer:
Solution:
Total volume of water = amount of water in each bottle x total number of bottles.
W = b x 17
Therefore,
W/b = 17
The equation that relates the number of bottle of water (b) to the total volume of the water (w) in fluid ounces is w = 17b.
We can multiply W by 1/b to get the amount of water stored in one bottle
Step-by-step explanation:
Substitute x = -4y into x+5y = 2.
-4y + 5y = 2
y = 2. Substitute this value into the first equation: x = -4 × 2 = -8.
So the answer is (-8,2).
Answer:
A. 19.3ft B. 5.2ft
Step-by-step explanation:
So the ladder leaning against the wall forms a triangle. The hypotenuse of
triangle is the ladder (20) and the angle given between ladder an ground is 75 degrees. Use trig to find the height of the wall which is the leg of the triangle.
Sine of Angle is opposite side/hypotenuse
Cosine of Angle is adjacent side/hypotenuse
so Sine of 75 degrees = Wall height/20
Wall height = 20 times Sine of 75 degrees
Sine of 75 degrees = .9659
20 times (.9659) = 19.3ft
So now use Cosine to find the other leg of the triangle (the distance between the bottom of ladder to the wall)
Cosine of 75 degrees = Distance wall to base of ladder / 20
Cosine of 75 degrees = .2588
20 times (.2588) = 5.2ft
