To find the volume of a cone you need to know this formula
1/3 x pie x r^2 x the length
R^2 : is the radius squared
Answer:
-343
Step-by-step explanation:
tn=a+(n-1)d
0(50-1)*-7
-343
-8x + 4 > 5 - 3x
Adding 3x to both sides,
-5x + 4 > 5
Subtracting by -4 on both sides,
-5x > 1
Dividing both sides by -5,
x < - 1/5
Answer:
12 days
Step-by-step explanation:
Set up an equation with y = mx + b, where m is the rate and b is the y-intercept (starting value)
Let x represent how many days it takes and y represent how many pages he read:
445 = 24x + 157
Solve for x:
288 = 24x
12 = x
So, it will take him 12 days to finish the book
2x+34 = 4(x+5)
2x+34 = 4x+20
-2x = - 14
x = 7
