Step-by-step explanation:
Mass (m) = 11 g
volume (v) = 13 ml
density (d) = ?
We know density is defined as mass per unit volume so
d = m / v
= 11 / 13
= 0.85 g/ml
Density (d) = 0.85 g/ml
Answer:
x=−y−1
Step-by-step explanation:
y=−x−1
Step 1: Flip the equation.
−x−1=y
Step 2: Add 1 to both sides.
−x−1+1=y+1
−x=y+1
Step 3: Divide both sides by -1.
−x
−1
=
y+1
−1
x=−y−1
Answer: 1120 feet
Step-by-step explanation:
ANSWER:
10
The length of line BC is 10.
EXPLANATION:
Triangle ABC is four times the area of triangle AYX.
Area of triangle ABC = 4 × Area of triangle AYZ
This is as:
30 = 4 × 7.5
THEREFORE:
The length of line BC must be twice of the length of line XY.
BC = 2 × XY
BC = 2 × 5
BC = 10
