Answer:
11.3 ft
Step-by-step explanation:
[tex]V_{gravel}=3,200\: ft^3\\\\height \:(h) =24\: ft\\\\ To \: find:\: radius\:(r)[/tex]
Since, gravel is in the shape of right circular cone.
[tex]\implies V_{gravel}= \frac{1}{3}\pi r^2 h\\\\\implies 3,200= \frac{1}{3}(3.14) r^2 (24)\\\\\implies r^2=\frac{3,200\times 3}{3.14\times 24}\\\\\implies r^2=\frac{9,600}{75.36}\\\\\implies r^2=127.388535\\\\\implies r=\pm\sqrt{127.388535}\\\\\implies r=\pm 11.286653\\radius\: can't\: be\: negative\\\\\implies r=11.286653\\\\\implies r \approx 11.3 \: ft[/tex]
OAB is a triangle
OA = 4a and OB = 5b
M is the midpoint of OB
AN:NB = 2:3
Find OP:PN
Answer:
5:2
Step-by-step explanation:
ON = OA + AN
AN = 2/5AB
AB = 5b-4a
AN = 2b - 8/5a
ON = 4a - 8/5a +2b
ON = 12/5a+2b
OP = k(12/5a+2b)
OP = OA + AP
AP = x(AM)
AM = 5/2b-4a
OP=4a-4ax+5/2bx
OP=4a-4ax+5/2bx and OP=12/5ak+2bk
Coefficients of A
4-4x=12/5k
k=(20-20x)/12
Coefficients of B
5/2x=2k
k=5/4x
(20-20x)/12 =5/4x
20=35x
x=4/7
k=5/4 * 4/7 = 5/7
OP=k(ON)
OP = 5/7
PN = 2/7
OP:PN = 5:2

In order to isolate 'x', we can use the number 'e' to cancel the natural log. The 'e' will cancel the natural log because they are inverse to each other:

[tex]2\sin^2 x =\sin x \\\\\implies 2 \sin^2 x - \sin x=0\\\\\implies \sin x(2 \sin x -1) =0\\\\\implies \sin x = 0~~\text{or}~~ 2 \sin x -1 =0\\\\\implies \sin x = 0~~ \text{or}~ ~ \sin x = \dfrac 12\\\\\text{For}~~ \sin x = 0\\\\x=n\pi \\\\\text{In the interval,}~~[0, 2\pi)\\\\x=0, \pi\\\\\text{For}~~ \sin x = \dfrac 12\\\\x=n\pi+(-1)^n \dfrac{\pi}6 \\\\\text{In the interval,}~~[0, 2\pi)\\\\x=\dfrac{\pi}6,~ \dfrac{5\pi}6\\\\\text{Hence,}~ x = 0,~\pi,~ \dfrac{\pi}6, ~\dfrac{5 \pi}6[/tex]
Answer:
[tex]x=0, \dfrac{\pi}{6},\dfrac{5\pi}{6},\pi \:\sf(for\:the\:given\:interval)[/tex]
Step-by-step explanation:
given interval [0, 2π) = 0 ≤ x < 2π
[tex]2\sin^2(x)=\sin(x)[/tex]
subtract sin(x) from both sides:
[tex]\implies 2\sin^2(x)-\sin(x)=0[/tex]
factor:
[tex]\implies \sin(x)[2\sin(x)-1]=0[/tex]
[tex]\sin(x)=0[/tex]
[tex]\implies x=0 \pm2 \pi n, \pi \pm2 \pi n[/tex]
[tex]\implies x=0, \pi \:\sf(for\:the\:given\:interval)[/tex]
[tex]2\sin(x)-1=0[/tex]
[tex]\implies \sin(x)=\dfrac12[/tex]
[tex]\implies x=\dfrac{\pi}{6} \pm2 \pi n, \dfrac{5\pi}{6} \pm2 \pi n[/tex]
[tex]\implies x=\dfrac{\pi}{6},\dfrac{5\pi}{6}\:\sf(for\:the\:given\:interval)[/tex]
Final solution:
[tex]x=0, \dfrac{\pi}{6},\dfrac{5\pi}{6},\pi \:\sf(for\:the\:given\:interval)[/tex]

If the candy was in whole of in peices
Step-by-step explanation:
A dependant variable is something you do to change a result, so breaking tha candy would be the dependant variable because they werre trying to see if breaking the candy would lead to diffrent results.
Just so you remember for next time:
an Indipendent variable is something that is constant that we can not change
and a dependent variable is something that we change to get a diffrent response.
If a student wants to multiply by 8 they can?
A. Multiply by 2 three times
B Multiply by 2 four times
C Multiply by 4 twice
D Multiply 2 and multiply by 4 and add them together
Hello Brainly user,
A. Multiply by 2 three times if you want to multiply by 8.
Proof:
For example, if you want to multiply 2 by 8 --> 2x8 then you can just do 2x2 = 4 4x2 = 8 8x2 = 16.
TO CHECK:
You can do 8x2 = 16.
Hence, this answer is 100% correct.

The figure below is made of 2 rectangular prisms.
What is the volume of this figure?
Answer:
1800.Step-by-step explanation:
First: split the figure into 2:
(5 * 9 * 2)*(5 * 4)Then, solve the first:
5 * 9 * 2= (5 * 9) * 2= 45 * 2= 90Next, solve the second part:
5 * 4= 20Finally, multiply both parts:
90 * 20= 1800.Answer is 1800.

Step-by-step explanation:
The angle measures for the triangle is 60, 60 and 60.
What is Triangle?A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.
We have,
The measure of three sides are 6 ,6 and 6.
Now, we know a triangle whose three sides are equal is called as Equilateral Triangle.
Also, three angles are Equal.
Using Angle Sum property
x + x + x = 180
3x= 180
x= 60
Thus, the measure of three angles are 60, 60 and 60.

39. Algebra A rectangle has a base of x units. The area is (4x2-2x)
square units. What is the height of the rectangle in terms of x?
A (4 - x) units
(x-2) units
B (4x3 - 2x2) units
D (4x - 2) units
-
-
The area of the rectangle is the product of its base and height
The height of the rectangle is 4x - 2 units
How to determine the height?The given parameters are:
Area = 4x^2 - 2x
Base = x
The area of the rectangle is:
Area = Base * Height
This gives
4x^2 - 2x = x * Height
Divide through by x
4x - 2 = Height
Rewrite as:
Height = 4x - 2
Hence, the height of the rectangle is 4x - 2 units

Give the equation the circle (X+5)^2+(y-1)^2=16, which correctly gives the center and radius of the circle
Answer:
Step-by-step explanation:
You have:
[tex](x+5)^2+(y-1)^2=16[/tex]
[tex](x+5)^2+(y-1)^2=4^2[/tex]
To find the center of the circle, you want to find the 'x' and 'y' values which make their respective term equal zero:
[tex](x+5)^2=0[/tex]
[tex](y-1)^2=0[/tex]
[tex]x=-5[/tex]
[tex]y=1[/tex]
The radius of the circle would be 4 due to the right side of the circle equation. Our circle is centered at (-5, 1) and has a radius of 4 units.
