very urgent
1.) solve the equation: 2p/25=6 and find p.
2.) find product, using suitable properties :
(26)x(58) – (16)x(58)
3.) An elevator descends into mine at the rate of 6m/min. If the descent starts from 10m above the ground level ,how long will it take to reach -350m.
4.) neha reads novel for 11/4 hours everyday . she reads entire book in 8 days . how many hours in all were required by her to read the novel ?
Answers
Answer:
1) 2p/25=6
=2p=6×25
=2p=150
=p=150/2
=p=75
2) (26)x(58) – (16)x(58)
=58(26-16)
=58×10
=150
3)Total distance covered by an elevator
=10−(−350)m=10+(350)=360mSo, time taken to cover a distance of 6m=1 min
Therefore, time taken to cover
360m= 360 ÷ 6 = 60minutes(1 hour =60 minutes)
Thus, the elevator will reach –350m from 10m in 1 hour.

Answer:
1)
2p/25=6
2p=6×25
p=150/2
p=75
2)
(26×58)-(16×58)
=1508-928
=580
3)
total distance an elevator has to decend=10+350=360m
rate of elevator is 6m/min
let the total time required will be x mins
6m/1min=360m/x min
6x=360
x=360/6
x=60min
ans: it will take 1 hr to reach -350 deep
4)
neha reads a novel for 11/4 hr everday
a day has 24hr
therefore its 11/4part will be 66 min i.e 1hr 6 min
she reads entire book in 8 days
total no. of hrs she required to read a novel = 1.6×8=8.48hrs
ans- she required 8.48hrs i.e 8hrs 48min to read entire novel
