Volumeofasphere = ar A Walmart employee has decided that they would like to completely fill the
ball bin in the toy section with one type of ball.
The ball he decided to use had a radius of 16 cm. The ball bin is 210 centimeters tall and the opening at the
top is 150 centimeters by 150 centimeters. How many balls should fit inside the bin?
Number of balls should fit inside the bin are 216 balls.
Given:
Radius of spherical ball = 16 cm
Height of cylinder = 210 cm
Diameter of opening = 150 cm
Find:
Number of balls should fit inside the bin
Computation:
Volume of sphere = [tex][\frac{4}{3}] [\pi ][r^3][/tex]
Volume of sphere ball = [tex][\frac{4}{3}] [\pi ][16^3][/tex]
Volume of sphere ball = 17164.19 cm³
Radius of cylinder = Diameter of opening / 2
Radius of cylinder = 150 / 2
Radius of cylinder = 75 cm
Volume of cylinder = [tex][\pi ][r^2][h][/tex]
Volume of cylinder = [tex][\pi ][75^2][210][/tex]
Volume of cylinder = 3,712,500 cm³
Number of balls should fit inside the bin = Volume of cylinder / Volume of sphere ball
Number of balls should fit inside the bin = 3,712,500 / 17,164.19
Number of balls should fit inside the bin = 216.293
Number of balls should fit inside the bin = 216 balls (Approx.)

Answer:

Step-by-step explanation:
Hi there!
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] where two points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
We're given that the campsite is located at (1,7) and the checkpoint station is located at (4,6). We must calculate the distance between them. Plug these points into the formula:
[tex]d=\sqrt{(x_2-1)^2+(y_2-7)^2}\\d=\sqrt{(4-1)^2+(6-7)^2}\\d=\sqrt{(3)^2+(-1)^2}\\d=\sqrt{9+1}\\d=\sqrt{10}\\d\approx3.16[/tex]
Therefore, the distance between the campsite and the checkpoint is 3.16 miles when rounded to the nearest hundredth.

Step-by-step explanation:
Starting from standard form ...
ax +by = c
and solving for y, we get the slope-intercept form ...
y = (-a/b)x +c/b
The coefficient of x is the slope: -a/b.
For your equation x+2y=16, the slope is -1/2 = -0.5.

What is the value of x?
Evaluate:

hello, anyone can help me if you don't mind, I am getting confused.
Thanks, I really appreciate
Recall some identities:
sin²(x) + cos²(x) = 1
cos(2x) = cos²(x) - sin²(x)
and from the first identity, you can establish that
cos(2x) = 2 cos²(x) - 1
So, rewrite the integrand as much as possible in terms of cos(x) :
[tex]\sin^3(x) \cos(2x) = \sin(x) \sin^2(x) (\cos^2(x)-\sin^2(x)) \\\\ \sin^3(x) \cos(2x) = \sin(x) (1-\cos^2(x)) (2\cos^2(x) - 1)[/tex]
Then in the integral, substitute u = cos(x) and du = -sin(x) dx. With some rewriting, you end up with
[tex]\displaystyle \int_1^2 \sin^3(x) \cos(2x) \,\mathrm dx = -\int_{x=1}^{x=2} (1-\cos^2(x))(2\cos^2(x)-1) (-\sin(x)\,\mathrm dx) \\\\ = -\int_{u=\cos(1)}^{u=\cos(2)} (1-u^2)(2u^2-1)\,\mathrm du \\\\ = \int_{\cos(1)}^{\cos(2)} (1-3u^2+2u^4) \,\mathrm du \\\\ = \left(u-u^3+\frac25u^5\right)\bigg|_{\cos(1)}^{\cos(2)} \\\\ = \left(\cos(2)-\cos^3(2)+\frac25\cos^5(2)\right) - \left(\cos(1)-\cos^3(1)+\frac25\cos^5(1)\right) \\\\ = \boxed{\cos(2) - \cos^3(2) + \frac 25 \cos^5(2) - \cos(1) + \cos^3(1) - \frac25 \cos^5(1)}[/tex]

A cube has a volume of 125 cubic inches. What is the length of each edge?
Enter your answer in the box.
(Needs to be in inches)
The formula for the volume of a cube is V = a^3.
We know the volume is 125 cubic inches.
125 = a^3
Take the third square root
5 = a
The length of each edge is 5 inches
Answer:
So the length of the edge of a cube with a volume of 125 is 5 inches
Step-by-step explanation:
All the edges of a cube have the same length, and the volume of a cube is the length of an edge taken to the third power.
So if we take the edge of the cube to be of length x, then:
Volume=x3
125=x3
5=x
Solve the equation. Check your solution.
Answer:
x = 5
Step-by-step explanation:
x^2/(x + 5) = 25/(x+5) Subtract the right side from both sides.
x^2/(x + 5) - 25/(x + 5) = 0
x^2 - 25
======= = 0
x + 5
(x + 5)(x - 5)
============= = 0
(x + 5)
Cancel x + 5 in the numerator and denominator.
x - 5 = 0
x = + 5
Does it check?
x^2/(x + 5) = 25/(x + 5)
x = 5
5^2/(10) = 25/10
25/10 = 25/10 Yes it checks.
y + (2/25) = 11/15
What’s y
Answer:
[tex]\frac{49}{75}[/tex]
Step-by-step explanation:
y= [tex]\frac{11}{15}[/tex]-[tex]\frac{2}{25}[/tex]
y= [tex]\frac{49}{75}[/tex]
Answer:
49/75
Step-by-step explanation:
y + 2/25 = 11/15
now, we could do it like the other answer and do fraction arithmetic, or we try and multiply everything out to eliminate the fractions :
15y + 30/25 = 11
375y + 30 = 275
375y = 245
y = 245/375 = 49/75
the same result, of course, but a slightly different way to get there.

what is the equation of a line parallel to y = -1/2x + 6 that passes through (-4, 1)
Answer:
y = -1/2x - 1
Step-by-step explanation:
A line that is parallel to another will have the same slope. All we need to do is find the new y-intercept. We can do that by using the slope intercept form equation [ y = mx + b ].
1 = -1/2(-4) + b
1 = 2 + b
-1 = b
Now we can input the information we know and solved for back into the formula.
y = -1/2x - 1

The sixth grade teachers bought food for a reward party. They purchased 64 bags of chips and 80 bottles of water . What is the largest number of students that can be invited to the party so they each get the same amount of chips and water?
Answer:
64
Step-by-step explanation:
Since each student must get the same amount of chips and water, the ratio of the number of chips to water received by each student is 1:1.
Hence, a maximum of 64 students can be invited to the party, as the bags of chips is lower than that of the number of bottles of water, and we take it as a 64.
