Answer:
0.7 kg
Step-by-step explanation:
x = mass of the empty container (just the container alone)
y = mass of the sand in the full container.
x + y = 1.26 kg
x + 5/8 × y = 1.05 kg
=>
x = 1.26 - y
(1.26 - y) + 5y/8 = 1.05
8×(1.26 -y) + 5y = 8×1.05
8×1.26 - 8y + 5y = 8×1.05
10.08 - 3y = 8.4
3y = 1.68
y = 0.56 kg
x = 1.26 - 0.56 = 0.7 kg
Parallel because they have the same slope. Y+4= -1/2(x-2) is in point slope form, simplified to y intercept form is y=1/2-5... The slope (m) in both equations is the same, if you graphed the equations they would be parallel
Answer:
y = 2 -> (-5, 2)
Step-by-step explanation:
To solve questions like these, you plug in the variable you know, which in this case, is <em>x = -5</em>.
That gives us <em>-5 - 5y = -15</em>.
Then, you solve it like a normal equation.
-5y = -10 (add 5 to both sides)
-y = -2 (divide by 5)
y = 2. (divide by -1)
Because the 2 triangles formed by the 2 guy ropes and the post are congruent by HL The H hypotenuse are the guy ropes equal in length and the L is the height of pole where the 2 guy ropes are attached.
