Answer:
The total surface area of this cuboid is 132.5 sq.cm
Answer:
1 ten.
Step-by-step explanation:
1 ten = 10 ones/units
The 24th term is 152
Step-by-step explanation:
The formula of the nth term of an arithmetic sequence is:
, where
- a is the first term
- d is the common difference between consecutive terms
The third term means n = 3
∵
∴
∵ = 5
- Equate the right hand sides of the third term
∴ a + 2d = 5 ⇒ (1)
The fifth term means n = 5
∵
∴
∵ = 19
- Equate the right hand sides of the fifth term
∴ a + 4d = 19 ⇒ (2)
Now we have a system of equations to solve it
Subtract equation (1) from equation (2) to eliminate a
∴ 2d = 14
- Divide both sides by 2
∴ d = 7
- Substitute the value of d in equation (1) to find a
∵ a + 2(7) = 5
∴ a + 14 = 5
- Subtract 14 from both sides
∴ a = -9
The twenty fourth term means n = 24
∵ a = -9 and d = 7
- Substitute the values of a and d in the formula of the nth term
∴
∴
∴
∴
The 24th term is 152

Answer:
26. D) $252
27. A) -6.7 + 6.8
Step-by-step explanation:
26. 400 * 0.3 = 120
400 - 120 = 280
280 * 0.1 = 28 (because the 10% is additional, cannot add it to the original 30%)
280 - 28 = 252
27. -4.5 + 4.4 = -0.1
- 6.7 + 6.8 = 0.1
-0.1 + 0.1 = 0
