Okay. So, Amber used 1/2 of the 4/5 bag for the art project. Let’s do 4/5 / 2. 4/5 * 1/2 is 4/10 or 2/5 in simplest form. Amber uses 2/5 of a pound of sand for her art project.
let the original price be x.
then,
x- 25% of x= 24
x- 25x/100 = 24
x- x/4=24
3x/4=24
3x= 96
x= 32
in short...the original price= 32 dollars
Answer:
r = 14.998 yd
Step-by-step explanation:
Volume of a cone
V = πr^2h/3
Given:
V = 3,532 yd cubed
π - 3.14
r = h
Since the radius and the height of the cone are equal
So, let r = h = x yd
V = 3.14 * x^2 * x/3
3532 = 3.14x^3/3
3532 = 1.047x^3
Divide both sides by 1.047
3532/1.047 = x^3
3373.45 = x^3
x = 14.998 yd
Since r = h = x
r = h = 14.998yd
r = 14.998yd
Hint: to check if the value of radius and the height are correct, insert the values into the formula
V = πr^2h/3
V = 3.14 * 14.998^2 * 14.998/3
= 3.14 * 224.940 * 4.999
= 3530.852
≈ 3531 yd cubed
Due to approximations
The answer you are looking for is 3.
To find this, you must first distribute the 3 into the parenthesis. 3 x 9 = 27 and 3 x 4 = 12.
Next, you subtract 12 from 27. 27 - 12 = 15.
Finally, divide 15 by 5 to get your final answer as 3.
I hope this helps!
Answer:
A) 8%
Step-by-step explanation:
A confidence interval of proportions has an upper end and a lower end.
The margin of error is the difference between these points divided by two. Also, it is the upper end subtracted by the estimated proportion, or the estimated proportion subtracted by the lower end.
In this problem, we have that:
Upper end: 0.68
Lower end: 0.52
Margin of error
The margin of error is 8%.
So the correct answer is:
A) 8%
