Answer:
Here's what I get
Step-by-step explanation:
aₙ is the nth term in the arithmetic sequence and aₙ₋₁ is the term that comes immediately before it in the sequence.
We know that a₅ = 23. To find a₈, we must find a₆ and a₇.
a₅ = 23
a₆ = a₅ + 5 = 23 + 5 = 28
a₇ = a₆ + 5 = 28 + 5 = 33
a₈ = a₇ + 5 = 33 + 5 = 38
Answer:
20 cm
Step-by-step explanation:
∵ S is the centroid of ΔNLM
∴ S divides NG at ratio 1 : 2 from the base
∴SQ = 1/2 NS
∴3x - 5 = 1/2 (4x)
∴3x - 5 = 2x
∴3x - 2x = 5
∴x = 5
∴ NS = 4 × 5 = 20 cm
D + r = 95.....d = 95 - r
8d + 5r = 628
8(95 - r) + 5r = 628
760 - 8r + 5r = 628
-8r + 5r = 628 - 760
-3r = -132
r = -132/-3
r = 44 <== regular cones
d + r = 95
d + 44 = 95
d = 95 - 44
d = 51 <== deluxe cones
Answer:8.9
Step-by-step explanation:
192/43 is about 4.46
4.46*2 is about 8.9
The ratio is 11 : 7. I.e the number of red apples are 11 and that of green are 7
