Answer:
1. 16
2. Ram=70 Raj=110
3. d+2, d+4, d+6
Step-by-step explanation:
1. p+2=6
p=6-2
p=4
5p-4=5(4)-4
=20-4
=16
2. Raj=40+Ram
Ram+Raj=180
Ram+40+Ram=180
Ram+Ram=180-40
2Ram=140
Ram=140/2
Ram=70
Raj=40+70
Raj=110
3. d, d+2, d+4, d+6.
Answer:
Step-by-step explanation:
First find the surface area of the clyinder and find the area circles and subtract
Then find the surface area of a cone, remove the circle area and double it.
Clyinder surface area (without circle area) 2πrh+2πr2=2·π·4·6+2·π·42≈251.32741
251.32741 - 50.2 - 50.2
Cone area: A=πr(r+h2+r2)=π·4·(4+32+42)≈113.09734
113.09734 - 50.2 - 50.2
Total: 12.69734 + 150.92741 = 163.62475
Answer:
Please check the explanation.
Step-by-step explanation:
Given the English statement
''The sum of two and number is less than five''.
Let us breakdown the statement.
- The sum of two and number = 2 + n
We know that the less than symbol is denoted by '<' which is used for comparison.
Thus, the statement 'The sum of two and a number is less than five' is algebraically represented as:
Let us solve the algebraic expression.
Subtract 2 from both sides
Simplify
Thus, the solution is:
Please also check the attached solution line graph.
length of pipe= 30m
Inside dia. = 1.2m
Outside dia. = 1.8m
Volume of concrete= (outside dia. - inside dia.)h
V= (pi)
v= [(3.14*0.9*0.9)-(3.14*0.6*0.6)]30
v= (3.3534-1.1304)30
v=(2.233)30 = 66.690m cube
since it's volume the answer 66.690 is in cubic meters.
