You dived 14.28/4.2 by taking the decimal out and when you get the answer put it back
Answer:
The sun is about 390 times farther than earth is from the moon
Step-by-step explanation:
It's kind of hard to understand the question but it's essentially asking how many times farther earth is from the sun than earth is from the Moon. Or basically measure the distance from the earth to the moon. Then show how much bigger the distance from the Earth to the Sun is by comparing it from the earth to the moon. To do this you divide the distance of moon by the distance of the sun to get how many times you could you could fit the distance between the Earth and The Moon from the Earth to the Sun.
Answer:
I'm confused as to what you are asking
You also did not attach any work haha
I cannot answer this
Answer:
OB = 8
OC = 8
OA = 8
AC = 16
BD = 16
OD = 8
Step-by-step explanation:
Given, rectangle ABCD, with diagonals AC and BD, and OC = 3x – 4, OB = x + 4,
thus, since diagonals of a rectangle are equal, therefore, AC = BD.
Invariably, 2*OC = 2*OB
Thus, 
Solve for x
Add 8 to both sides
Subtract 2x from both sides
Divide both sides by 4
OB = x + 4 = 4 + 4 = 8
OC = 3x - 4 = 3(4) - 4 = 12 - 4 = 8
OA = OC = 8
AC = 2*OC = 2*8 = 16
BD = 2*OB = 2*8 = 16
OD = OB = 8
Answer:
value of k = 6
Step-by-step explanation:
sum of all angles forming a straight line = 180°
so,
- 7k + 8 + 90 + 40 = 180
- 7k + 138 = 180
- 7k = 180 - 138
- 7k = 42
- k = 42/7
- k = 6
hence the value of k = 6
