Hello,
Answer:
The last graph (2;3)
Step-by-step explanation:
2x + 3y = 12
2x – 3y = 0
2x + 3y = 12
2x = 3y
3y + 3y = 12 ⇔ 6y = 12 ⇔ y = 12/6 = 2
2x + 3 × 2 = 12 ⇔ 2x + 6 = 12 ⇔ 2x = 6 ⇔ x = 6/2 = 3
Circumference of the wheel = pi*d = 26pi ins = 13pi / 6 feet
there are 8280 feet in 1 mile
The number of revolutions in travelling 1 mile = 5280 * 6
----------- = 776 revs
13 pi
Answer:
225 thousand.
Step-by-step explanation:
You are dividing the number in half every time.
Answer:
37°
Step-by-step explanation:
since <1 +<6=180° (sum of co interior angles)
143°+<6= 180°
<6=180°-143°
<6= 37°
m<6=m<7 (vertically opposite angles)
Hence m<6=37°
m<7=37°
