Answer:
275=n× n by 216
Step-by-step explanation:
The mean of a set of numbers is the sum divided by the number of terms.So, 20+24+12+44+68 / 5
mean = 33.6
Answer:
64 bags
Step-by-step explanation:
number of bags sold by Takis Scorpion BBQ = x
Number of bags sold by Takis Valcano Quesco = 3x - 6
the total number of bags = x + ( 3x - 6 )
x + 3x - 6 = 250
therefore, 4x - 6 = 250
4x = 250 + 6
4x = 256
dividing through by 4
x = 64
it takes 5 seconds to reach a height of 40 ft. and It takes 2.5 seconds to reach maximum height.
Let h(t) represent the height of the ball at time t.
Given that the height is given by:
h(t) = -16t² + 80t + 40
1) For the ball to reach a height 0f 40 ft, h(t) = 40, hence:
40 = -16t² + 80t + 40
16t² - 80t = 0
t(t - 5) = 0
t = 0 or t = 5
Hence it takes 5 seconds to reach a height of 40 ft.
2) The maximum height is at h'(t) = 0,
h'(t) = -32t + 80
-32t + 80 = 0
32t = 80
t = 2.5
It takes 2.5 seconds to reach maximum height.
