Answer:
$0.25
Step-by-step explanation:
To find unit rate divide number of shirts by cost of package
$2.00/8 = $0.25
So each individual golf tee costs $0.25

Answer:
The 8th term in the sequence is -128
Step-by-step explanation:
The given series is a geometric progression (G.P) with the starting term as -1.
Let the starting term be a and the common ratio be r.
a = -1
r = 2
The formula for the nth term of a geometric progression (G.P) :
n = 8
Therefore, the 8th term in the sequence is -128
Step-by-step explanation:
x = one odd number
the second odd number is (x+2), as both are consecutive.
so,
x × (x + 2) = 195
x² + 2x = 195
x² + 2x - 195 = 0
the formula to solve this is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = 2
c = -195
x = (-2 ± sqrt(4 - 4×1×-195))/(2×1) =
= (-2 ± sqrt(4 + 4×195))/2 = (-2 ± sqrt(784))/2 =
= (-2 ± 28)/2 = -1 ± 14
x1 = -1 + 14 = 13
x2 = -1 - 14 = -15 which is invalid as the numbers are positive.
so, the two numbers are 13 and 15.
Answer:
30 min
Step-by-step explanation:
She takes 45 minutes to run 6 miles.
Lets simplify this. If we divide by 3, then we know that:
She takes 15 minutes to run 2 miles.
Therefore, to find the amount of time it takes to run 4 miles, we just multiply 15 by 2.
Therefore it takes her 30 mins to run 4 miles.
