Circumference of a circle = 
Circumference = 
Answer:
1/3
Step-by-step explanation:
We require the quantities to have the same dimensions.
Using the conversion
1 metre = 100 cm, then
2.1 m = 2.1 × 100 = 210 cm
The fraction can then be expressed as
70/210← divide numerator/ denominator by 70
= 1/3 ← in simplest form
Answer:
See below
Step-by-step explanation:
Remember that y=mx+b:
1) y = -3x+7
2) y = 1/4x-5
I guess the function is a parabola with vertex at (0,0) and opens down so the range is (-infinity, 0].
Step-by-step explanation:
k =70 because all triangles angles add up to 180° and it's an acute angle cause all the angles are lower than 90° hope this helps
