1. 30/23, do the math, if you cant do simple math, use a calculator
2a. 2.60 x 35 = distance of the laps together
t = d/s
t = distance of the laps ÷ 182m/h
2b. You have the info, do it urself
3a. 30 x 6. Not that hard, giving you hints here
3b. Look at the answer at 3a, now look at what your friend wrote. Clearly he/she listened to some dumb person on brainy
4. s = d/t
s = 22/30. Again, use a calculator
I did basically all the work for you. Just get up your lazy butt to get a calculator. Not that hard! I probably am smaller and younger than you!
I better get brainilest for this...
You're welcome :)
Answer:
x=πn, n∈Z
Step-by-step explanation:
if sin²2x=1-cos²2x, then
1-cos²2x-2cos2x+2=0; ⇒ cos²2x+2cos2x-3=0; ⇔ (cos2x+3)(cos2x-1)=0;
Answer:
i think x its 8

Answer:
Y= 5
Step-by-step explanation:
14+13Y=20Y-21
-13y -13y
14=7y-21
+21 +21
35/7=7y/7
y=5
Answer:
2464 yd²
Step-by-step explanation:
Use the circle circumference formula: 2πr
2·
·r=176
r=176
r=176·
r=28
Area of circle formula: πr²
·r²
·28²
·784
=2464 yd²
