Answer:
6.0435*10²⁴
Step-by-step explanation:
Moon: 7.35*10²²
Earth: 5.97*10²⁴
7.35*10²² = 0.0735*10²⁴
then:
0.0735*10²⁴ + 5.97*10²⁴ = (0.0735 + 5.97)*10²⁴
= 6.0435 *10²⁴
Answer: B. d - 0.2
Step-by-step explanation: 20%= 20/100= 0.2
Which means = d-0.2
Hope this helped.

Answer:
1) ΔACD is a right triangle at C
=> sin 32° = AC/15
⇔ AC = sin 32°.15 ≈ 7.9 (cm)
2) ΔABC is a right triangle at C, using Pythagoras theorem, we have:
AB² = AC² + BC²
⇔ AB² = 7.9² + 9.7² = 156.5
⇒ AB = 12.5 (cm)
3) ΔABC is a right triangle at C
=> sin ∠BAC = BC/AB
⇔ sin ∠BAC = 9.7/12.5 = 0.776
⇒ ∠BAC ≈ 50.9°
4) ΔACD is a right triangle at C
=> cos 32° = CD/15
⇔ CD = cos32°.15
⇒ CD ≈ 12.72 (cm)

Answer:
The final result is 1
Step-by-step explanation:
Remember the following:
And that x^0= 1
We have: 8^7 / 8^7= 8 ^ (7-7)=8^0=1
