The sum of the first 75 terms of the arithmetic sequence that has 10th term as 16 and the 35th term as 66 is 5400.
<h3>How to find the sum of terms using Arithmetic sequence formula</h3>
aₙ = a + (n - 1)d
where
Therefore, let's find a and d
a₁₀ = a + (10 - 1)d
a₃₅ = a + (35 - 1)d
Hence,
16 = a + 9d
66 = a + 34d
25d = 50
d = 50 / 25
d = 2
16 - 9(2) = a
a = 16 - 18
a = -2
Therefore, let's find the sum of 75 terms of the arithmetic sequence
Sₙ = n / 2 (2a + (n - 1)d)
S₇₅ = 75 / 2 (2(-2) + (75 - 1)2)
S₇₅ = 37.5 (-4 + 148)
S₇₅ = 37.5(144)
S₇₅ = 5400

Answer:
Circle
Step-by-step explanation:
When a plane passes through a 3-dimensional figure to create a cross section that is parallel to the base, the resulting 2-dimensional shape of the cross section is the same as the shape of the base.
The base of an ice cream cone is a circle, therefore the answer is circle
Answer:
24, 48, 108
Step-by-step explanation:
2:9:4
2x+9x+4x=180
15x=180
x=12
2(12)=24
9(12)=108
4(12)=48
Answer:
1496
Step-by-step explanation:
A = lw
22 x 16 = 352 ( bedroom)
22 x 18 = 396 (living)
352 + 396 = 748
748 x 2 = 1496
