Answer:
The correct answer is 0.0667 centimeters.
Step-by-step explanation:
Diameter of earth is 12700 kilometers.
Width of the solidified ocean crust is 35 kilometers.
Ratio between the diameter of the earth and the solidified crust is
.
Now the earth is shrunken to a size of a basketball with the diameter as 24.2 centimeters. Let the thickness of the Earth's crust in this model be x centimeters.
Ratio between the diameter of the model earth and the solidified crust is
.
But this ratio of the real Earth and its model must be equal.
∴
= 
⇒ x = 0.0667 centimeters.
Answer:
y=-3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-3-(-3))/(3-(-4))
m=(-3+3)/(3+4)
m=0/7
m=0
y-y1=m(x-x1)
y-(-3)=0(x-(-4))
y+3=0(x+4)
y+3=0
y=0-3
y=-3
Answer:
500
Step-by-step explanation:
First we make an equation to find the score for the bonus round. x is the score for the bonus round .
300 + x = 800
Next we subtract 300 from both sides of the equation
300 - 300 + x = 800 - 300
Which get us
0 + x = 500
x = 500
Her score in the bonus round is 500
