Hey!
First, we need to know how many millimeters are in a centimeter.
<em>10 mm = 1 cm</em>
Okay, now we can write an equation.
<em>360 mm ÷ 10</em>
To solve this equation, we simply divide.
<em>360 mm ÷ 10 = 36 cm</em>
<em>So, if </em><span><em>Anoki bought 360 millimeters of fabric, that means he has </em> 36.0 centimeters <em>of fabric.</em>
Hope this helps!

Answer:
y=3
Step-by-step explanation:
Multiply 9 from both sides to cancel it out.
-27=-y/9
/9 /9
-3=-y
We can't have a negative variable, so we divide -1 from both sides.
-3=-y
/-1 /-1\
3=y

Option C:
x = 90°
Solution:
Given equation:
<u>To find the degree:</u>
Subtract 1 + cos²x from both sides.
Using the trigonometric identity:
Let sin x = u
Factor the quadratic equation.
u + 2 = 0, u – 1 = 0
u = –2, u = 1
That is sin x = –2, sin x = 1
sin x can't be smaller than –1 for real solutions. So ignore sin x = –2.
sin x = 1
The value of sin is 1 for 90°.
x = 90°.
Option C is the correct answer.
All you have to do is multiply 84 by 25%
And that's your answer.
I hope this helped
