Answer:
A
Step-by-step explanation:
The area (A) of a triangle is calculated using the formula
A =
bh ( b is the base and h the perpendicular height )
here b = 14 and h = 4, hence
A =
(14 × 4) = 28
Answer: The instrument weigh 204 ounces on Earth.
Step-by-step explanation:
Since we have given that
Instrument weighed on the moon = 34 pounds
As we know that
The force of gravity on Earth is 6 times greater than on the moon.
So, the weight of instrument on the earth is 6 times the weight on the moon.
Mathematically, it is expressed as

Hence, the instrument weigh 204 ounces on Earth.
Answer:
6. D.
7. F.
8. A.
9. B.
10. C.
Step-by-step explanation:
6. 9 + (12 - 10)
12 - 10 = 2
9 + 2 = 11
7. (20 - 15) x 2
20 - 15 = 5
5 x 2 = 10
8. 10 ÷ 5 + 7
10 ÷ 5 = 2
2 + 7 = 9
9. 6 + 2 x 3
2 x 3 = 6
6 + 6 = 12
10. (2 x 4) + 8
2 x 4 = 8
8 + 8 = 16
