Answer:
1.167
Step-by-step explanation:
4/5 + 2/3 + 7/10
LCM 5 * 3 * 2 = 30
24/30 + 20/30 + 21/30
65/30 = 1 5/30 = 1 1/6 = 1.167
Answer:
35/4 =8¾
Step-by-step explanation:
using pythagoras theorem
hyp²=opp²+adj²
recall that tanX= opp/adj
taking our opposite side to be 3 and the adjacent side to be 4 , the hyp² = 3²+4²
hypotenuse = 5
recall also that , sinX = opposite /hypotenuse
= 3/5
CosX= adjacent /hypotenuse
=4/5
so we've known tanx = 3/4 cosX = 4/5 sinx= 3/5
substitute these values into your equation
it will give us 3/5 + 4/5 divided by 4/5 ×(1-4/5)
=35/4 = 8¾
2. F = ma
a.) Solve this equation for a (isolate the a)
F = ma Divide m on both sides
b.) F = -25
m = 10
a = ?
a = -2.5
c.) F = 25
a = 5
m = ?
F = ma
25 = m(5) Divide 5 on both sides
5 = m
(don't forget the units, because I forgot to put the units)
The question is asking for how many minutes it walks. Since it walks 5 meter per minute and walks 62.5 meters, you have to divide 62.5 by 5 to get how many minutes the tortoise walks. 62.5 divide by 5 is 12.5. in minutes, 0.5 is 30 seconds, therefore the tortoise walked for 12 minutes and 30 seconds or 12 1/2 minutes.
