you wrote the answer for D wrong.
ANSWER: D. 73/150
Given:
r = 3.8x10⁵ km = 3.8x10⁸ m, the distance between the earth and moon,
F = 20.46x10²⁵ N, the gravitational force between the earth and the moon,
G = 6.674x10⁻¹¹ m³/(kg-s²), gravitational constant
M = 5.972x10²⁴ kg, the mass of the earth.
Let m = mass of the moon.
Then
F = (G*M*m)/r^2
or
m = (F*r^2)/(G*M)
In SI units,
m = [20.46×10²⁵ * (3.8×10⁸)²]/[6.674×10⁻¹¹ * 5.972×10²⁴]
= 7.4125×10²⁸ kg
Answer: 7.4125x10²⁸ kg
6 pencils = 2 rulers
1ruler= 2 eraser
12 pencil = 4 rulers
4rulers=8 eraser
so 8 erasers are equal to 12 pencils
5 7/8 - 2 9/10
we can make 5 7/8 into an improper fraction of 47/8
we can also make 2 9/10 into an improper fraction of 29/10
find a common multiple between the denominators 10 and 8 - the smallest would be 40
47/8 will be made into 235/40
29/10 will be made into 116/40
235/40 - 116/40 = 119/40
simplify 119/40 and you get 2 39/40
decimal form is 2.975
Answer:
E. 22
Step-by-step explanation:
Hello!
We know that b>6, and we are asked to find the possible values for 3b + 3.
Let's directly substitute 6 for b:
Now, because b is greater than 6, and not equal to 6, any value greater than 21 will work.
The correct option is E. 22.
