Answer:
C = 12.57
Step-by-step explanation:
Circumference formula: C = 2πr
divide 4 by 2
4/2 = 2
plug it in
C = 2π(2)
C = 12.57
Answer:
x+1
Step-by-step explanation:
Y=-4
This line also is equals Zero, if that makes any sense lol but y= -4 is the correct equation.
Answer:
x = 6
Step-by-step explanation:
3x + 5 = 5x - 7
Combine like terms:
3x - 5x + 5 = -7
-2x + 5 = -7
Subtract 5 on both sides
-2x + 5 - 5 = -7 - 5
-2x = -12
x = 6
Hope this helps!! :)
Answer:
The altitude is 33 thousand feet at the given temperature
Step-by-step explanation:
We firstly would need to write out the rule.
We can do this by by doubling h, subtracting 15 and multiply the result by -1
Kindly note that h is in thousands of feet
That would be ;
T = (2 * h - 15) * -1
T = -1(2h - 15)
T = -2h + 15
T = 15 - 2h
So for the altitude in feet at a temperature of - 51 degrees Fahrenheit
We simply substitute the value of -51 for the temperature
So we have;
-51 = 15 - 2h
2h = 15 + 51
2h = 66
h = 66/2
h = 33 thousand feet
