Answer:

0.000002015 is not equal to 2.015x10^6

Step-by-step explanation:

When a power of 10 is positive the dot must be moved to the right, and when the power of 10 is negative, the dot must be moved to the left.

For example 50.000x10^3=50000 and 45.00x10^{-3}=0.045

So

2.015x10^6=2,015,000

wich is clearly not equal to 0.000002015

the correct scientific notation for 0.000002015 must be:

2.015x10^{-6}

With a negative in the power of 10, referring to a small quantity.

In the rhombus, angle 1=9x, angle 2=y+x, and angle 3=15z. Find the value of each variable. The diagram is not to scale.
notka56 [123]
From the diagram, all three angles are 90° (Diagonals of a Rhombus)

Angle 1 = 9x = 90
⇒ 9x = 90
x = 90/9
x = 10


Angle 2 = y + x = 90
⇒ y + x = 90
since x = 10,
y + 10 = 90
y = 90 - 10
y = 80


Angle 3 = 15 z = 90
⇒ 15z = 90
z = 90/15
z = 6

Answer is Option C
<span>C. x = 10, y = 80, z = 6</span>
