Answer:
Step-by-step explanation:
2.788 x 10^7
so 2.788 x 10 to the power of 7 = 1 mile
Answer:
Combine like terms
Step-by-step explanation:
-2x+4x=2x
6+5=11
So the answer is 2x+11
Green = -1x - 1
Black = -2x
Orange = Y = 4
Blue = X = -4
Answer:
y = 16.3
Step-by-step explanation:
We would apply the formula for altitude of a right triangle which is given as:
h = √(xy)
Where,
h = 14
x = 12
y = y = ?
Plug in the values
14 = √(12*y)
14² = (√(12*y) (squaring both sides)
196 = 12*y
196/12 = 12y/12 (division property of equality)
16.3 = y (nearest tenth)
y = 16.3
To find this answer, we need to multiply 3.57 by 12.
Therefore, 12 planks will cost $42.84.
