Answer:
The work will be finished in 10 days.
Step-by-step explanation:
Rashid can do a piece of work in 8 days
This means that each day he works, Rashid does of the work.
Tipu can finish in 12 days.
This means that each day he works, Tipu does of the work.
Each 2 days:
Each 2 days they work, the amount done is given by:
Each 2 days, 5/24 of the work is done:
The number of periods of 2 days that is needed to finish the work(100% = 1 completed), is given by:
2*4.8 = 9.6
Rounding up
The work will be finished in 10 days.
All of the telephones * all of the telephones minus one (because one is in use)
85 * 84 = 7140 connections
15% of 125 = 18.75 the tip
125 + 18.75 = 143.75 full price
Hope it helps!
Answer:
5. a) 2.140 + 1.725 = 3.865
b) 29.99 + 1.42 = 31.41
c) 6.157 - 1.009 = 5.148
6) 7.4 - 0.0022 = 7.2978 ✅
7.39 - 0.0012 = 7.3888
7. 140minutes / 2 hours and 20 minutes
Answer: First option 13
Solution
If ABCD is a rhombus, the diagonals must be perpendicular, then the angle (5x+25)° must be a right angle (90°):
(5x+25)°=90°
5x+25=90
Solving for x: Subtracting 25 both sides of the equation:
5x+25-25=90-25
Subtracting:
5x=65
Dividing both sides of the equation by 5:
5x/5=65/5
Dividing:
x=13
Answer: The value of x must be 13
