Answer:
75
Step-by-step explanation:
When you normally find a percentage of something you multiply. So, if you do the reverse operation, or divide, you'll get your answer.
18/24% is 75. And when you double check this by multiplying 75 by 24% you get 18. So, the bag of skittles <u>had</u> a total of 75 skittles.
Radius of circle= 4
a) circle circumference=2(pi)r
circumference=2(pi)4=25.13
P=2W+2L
p=2(5)+2(10)
P=30
b) area of circle=pi(r^2)=pi(16)=50.27
area of rectangle=L×W= 5×10= 50
c) I think you can figure it put
Answer:
512
Step-by-step explanation:
Beacuse 4x3 =32 32 x 16 =512
Step-by-step explanation:
h(t) = -5t² + 20t + 18
this is a parabola (the curve an object follows when thrown up into the air and then falling back down).
and as such it will most likely have 2 solutions (one for when going up, and one for when falling back down again).
33 = -5t² + 20t + 18
15 = -5t² + 20t
-3 = t² - 4t
t² - 4t + 3 = 0
the solution of such a quadratic equation is
t = (-b ±sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = -4
c = 3
t = (4 ±sqrt(16 - 4×1×3))/(2×1) = (4 ±sqrt(16-12))/2 =
= (4 ±sqrt(4))/2 = (4 ± 2)/2
t1 = (4+2)/2 = 6/2 = 3
t2 = (4-2)/2 = 2/2 = 1
the object reaches the height of 33 m first after 1 second (while going up), and then again after 3 seconds (while falling down again).
