The answer would be 34.3. Since you are rounding to the nearest tenth, you have to look at the hundreds place which is 8. 8 rounds up so therefore, 2 rounds up and becomes 3. Hope this helps!
Answer:
8xy that is the answer...................
Does it say if the angles are congruent?
Answer:
1) x = 14°, y = 5°
2) x = 18.5°, y = 37°
Step-by-step explanation:
1) ∠AOC and ∠BOD are vertical angles, then ∠BOD = 25°
∠MOD = ∠MOB + ∠BOD = 90°
3x + 23° + 25° = 90°
3x = 90° - 23° - 25°
x = 42°/3
x = 14°
∠LOB = ∠LOM + ∠MOB = 90°
5y + 3x + 23° = 90°
5y = 90° - 23° - 3(14°)
y = 25°/5
y = 5°
2) ∠AOC and ∠BOD are vertical angles, then ∠BOD = 16°
∠EOB = ∠EOD + ∠DOB = 90°
2y + 16° = 90°
y = (90° - 16°)/2
y = 37°
∠DOF = ∠BOF + ∠DOB = 90°
4x + 16° = 90°
x = (90° - 16°)/4
x = 18.5°
Answer: $786
Step-by-step explanation:
first hour = $50
Second hour = $60
Third hour = $72
Total amount after 24 hours :
4th hour = 72 + 1 4 = 86
5th = 86 + 16 = 102
6th = 102 + 18 = 120
7 = 120 + 20 = 140
8 = 140 + 22 = 162
9 = 162 + 24 = 186
10 = 186 + 26 = 212
11 = 212 + 28 = 240
12 = 240 + 30 = 270
13 = 270 + 32 = 302
14 = 302 + 34 = 336
15 = 336 + 36 = 372
16 = 372 + 38 = 410
17 = 410 + 40 = 450
18 = 450 + 42 = 492
19 = 492 + 44 = 536
20 = 536 + 46 = 582
21 = 582 + 48 = 630
22 = 630 + 50 = 680
23 = 680 + 52 = 732
24 = 732 + 54 = 786
