60% more than regular size. 230.4.
0 = -16t² + 36t + 4
0 = -8t² + 18t + 2 ← Complete the square to solve
-8(t² - 9t/2) = -2
8(t² - 9t/4 + 81/64) = 2 + 81/8
8(t - 9/8)² = 97/8
(t - 9/8)² = 97/64

Answer:
25p+45 < 480
Step-by-step explanation:
An integer is a whole number.
The answer isn't A, because 6/3=2 and 2 is a whole number.
The answer isn't C, because 6/2=3, and 3 is a whole number.
The answer therefore has to be B, because 3/6=1/2 and 1/2 isn't a whole number or an integer.
Answer:
C = 28.26 cm
Step-by-step explanation:
The figure shows a circle of diameter 9 inches.
The person has taken radius r as 9 inches which is wrong.
The radius must be (9/2) = 4.5 inches, such that,
Circumference = 2πr
= 2×3.14×4.5
= 28.26 cm
Hence, this is the required solution.
