Answer: 160 tablespoons
Step-by-step explanation:
Find 20% of 200. 200 x .20 = 40.
Subtract that 20%. 200-40=160.
The input is the y
y = x^2 - 5
plug in what we're given
-1 = x^2 -5
add 5 to both sides
4 = x^2
take the square root of both sides
2 = x
Hope this helps :)
Answer: 646
Step-by-step explanation:
((1/2)^2)^(-3) = (1/4)^(-3) = (1/(1/4))^3 = 4^3 = 64.
When the bucket hits the ground, h = 0. Therefore, set <span>h= -16t^2 + 9 = 0 and solve the resulting equation for t:
9
16t^2 = 9; t^2 = ----- ; taking the positive square root of both sides, t = 3/8 sec
16
Think the painter could or could not catch the bucket in 3/8 sec or less?</span>
1 hour. The experienced painter will paint 3 walls (1 every 20 minutes) while the inexperienced painter will paint one wall in the hour.
