Answer is (B) Both statements are needed.
Answer:
d ≈ 21.26 units
Step-by-step explanation:
calculate the distance d using the distance formula
d =
with (x₁, y₁ ) = (- 3, 8 ) and (x₂, y₂ ) = (13 - 6 )
d =
=
=
=
=
≈ 21.26 units ( to 2 dec. places )
Answer:
2291,94 mph
Step-by-step explanation:
To solve this we need to consider the distance 2.39x10^5 miles as the distance between the center of the earth and the center of the moon, if not we would need to know the radius of the earth and the moon.
If the distance is 2.39x10^5 miles, the orbit is = 2.Pi.(2.39x10^5) miles=1501681.288miles
It takes 27.3 days, that are, 27.3*24= 655.2hours
1501681.288miles/655.2hours= 2291.94 mph
Answer:
A. in Step 3
Step-by-step explanation:
It is factored correctly. Then separated into two smaller equations correctly. But in solving x + 10 = 0, there is an error.
x + 10 = 0
Add -10 to both sides.
x = -10
So, the error is in step 3.
Answer: If I were you, I would guess 320 students.
Step-by-step explanation:
1.) Think about it, 400 students were asked the same question and 80 chose to fight for lemonade on the school menu. 4/5 or 320 students put Guess.
2.) It's true that 400 students voted, but 80 voted yes, and 320 voted guess.
3.) Further Explanation:
1/5 times 400 equals 80. It's true only 80 students voted yes. 4/5 times 400 equals 320 students voted guess.
