Answer:
Samantha payed 12.71$ for her purchase.
Step-by-step explanation:
I may have misunderstood the question, but it looks like you can use a calculator for this!
6.19 + 2.85 + 2.29 + 1.38 =
12.71
Answer:
± 1/4 sqrt((400-y)) =t
Step-by-step explanation:
Y=-16t^2 + 400
Subtract 400 from each side
y - 400 = -16t^2 +400-400
y-400 = -16t^2
Divide by -16t^2
(y-400)/-16 = t^2
(400-y)/16 = t^2
Take the square root of each side
±sqrt((400-y)/16) =sqrt(t^2)
±sqrt((400-y)) / sqrt(16) =t
± 1/4 sqrt((400-y)) =t
A. Let us assume the width of the pool = x
Then
Length of the pool = 3x + 3
Depth of the pool = 2(3x + 3) - 7
= 6x + 6 - 7
= 6x - 1
B. Area of the land space = Width * length
= x * (3x + 3)
= 3x^2 + 3x
C. Volume of the pool = (6x - 1) * (3x^2 + 3x)
= 18x^3 + 18x^2 - 3x^2 - 3x
= 18x^3 + 15x^2 - 3x
D. The highest degree is actually 3 and the number of terms that we get is also 3.
Probability that the first card is not a club is 1 minus probability that it is a club. i.e. 1 - 1/4 = 3/4
Probability that the second card is not a heart is 1 minus probability that it is a heart. i.e. 1 - 1/4 = 3/4
Probability that the first card is not a club AND the second card is not a heart is 3/4 x 3/4 = 9/16
