A sphere has a volume of 4,500 cubic feet. Find the radius of the sphere.
Step-by-step explanation:
Volume of a sphere is
[tex]v = \frac{4}{3} \times \pi \times {r}^{3} [/tex]
We are given the volume, v, and asked to find the radius, r.
Substitute 4500 ft^3 for v, solve for r.
[tex]4500 = \frac{4}{3} \times \pi \times {r}^{3} [/tex]
Multiply both sides by 3/4 to eliminate 4/3
[tex] \frac{3}{4} \times 4500 = \frac{4}{3} \times \pi \times {r}^{3} \times \frac{3}{4} [/tex]
[tex] \frac{13500}{4} = \pi \times {r}^{3} \: \\ then \: divide \: by \: \pi[/tex]
[tex] \frac{3375}{\pi} = {r}^{3 \: \: take \: the \: cubed \: root \: of \: both \: sides} [/tex]
[tex] \frac{ \sqrt[3]{ {15}^{3} } }{ \sqrt[3]{\pi} } = \sqrt[3]{r} [/tex]
[tex] \frac{15}{ \sqrt[3]{\pi} } = r [/tex]
That approximates to 10.27 ft^3

|6-8|=2
Step-by-step explanation:
You see, absolute value makes any number positive. It doesn't matter if the number was already positive or negative. |x|>=0. If that makes sense. So, 6-8 would be -2. But -2 in absolute value would be 2.

What is the length of r and t ?
The width of a rectangle measures (2p-5) centimeters, and its length measures (8p+8)centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?
Answer: The expression that represents the perimeter, in centimeters, of the rectangle=20p + 11 centimeters
Step-by-step explanation:
Perimeter of a rectangle = 2(l+w)
length measures (8p+8)centimetres.
width measures (2p-5) centimeters,
Such that Perimeter= 2 L +2 W
Perimeter= 2( 8p+8) + 2(2p-5 ) This gives the expression to solve for the Perimeter
Solving
Perimeter= 2( 8p+8) + 2(2p-5 )
Permeter= 16p+ 16+ 4p-5
Perimeter= 16p+4p+16-5
Perimeter= 20p + 11 centimeters
Use the distributive property to remove the parentheses.
-4(p - 212) = 44
Solve for the remaining two step equation.
I need this very quickly
Answer:
P = 201.
Step-by-step explanation:
In mathematics, distributivity is a property of binary operations in which the multiplication is distributed, dividing the same multiplier by the different multipliers to obtain the result.
Thus, to solve the equation -4 (P - 212) = 44 the following calculation must be performed:
-4 (P - 212) = 44
(-4 x P) - (-4 x 212) = 44
-4P - (-848) = 44
-4P + 848 = 44
-4P = 44 - 848
-4P = -804
P = -804 / -4
P = 201

use the graph to estimate the solution to the system of equations shown.
A. x=5 1/2, y= 3 1/4
B. x= -3 1/2, y= -5 1/4
C. ×= 3 1/2, y= 5 1/4
D. x= -5 1/2, y= -3 1/4
==============================================================
Explanation:
The solution occurs where the two lines intersect. From this intersection point, draw a vertical line upward until you reach the x axis. We arrive somewhere between -5 and -6. A good estimate is to say that we're at the midpoint, so x = -5 & 1/2 is one possible estimate
Since only choice D has this x value, this must mean choice D is the answer. The y coordinate of y = -3 & 1/4 seems to fit as well since we can draw a horizontal line from the point of intersection to the y axis, and arrive somewhere just a little below -3.
Graph the line with a slope of 2/3 that contains the point (−3,−5)
Answer:
Step-by-step explanation:
So for the given information, it would be easiest to use slope-intercept form, which is y=mx + b, where m is the slope and b is the y-intercept.
We can plug in 2/3 for the slope, because we are given that.
y=2/3x + b.
To find the y-intercept, plug in the given point for x and y and solve for b.
-5 = 2/3 · (-3) + b
-5 = -2 + b
b = -3
So now we have the complete equation of the line.
y = 2/3x -3
Now to graphing.
We can put the y-intercept, (0, -3), and the given point, (-3, -5) on a graph.

what is the slope of the line containing the points (1,10) and (-3,10)
Answer:
0
Step-by-step explanation:
Slope is Rise over Run (y / x).
For 2 points, you would take the difference of y-coordinates and divide by the difference of x-coordinates.
(Y1 - Y2) / (X1 - X2)
Since both y-coordinates are the same (ten minus ten), your slope is zero (zero divided by anything is zero).

a typical tip in a restaurant is 18% of the bill. If the bill is 150,what would the typical tip be
You want to leave a 18% tip on a meal that cost $150.
First, convert the 18% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 18%) by 100%.So, the conversational term "18%" becomes 18% / 100% = 0.18 in terms of a real mathematical number.
Second, you need to find out what 18% of your $150 meal cost is.This is always done by multiplying 0.18 by $150.00, or
0.18 x $150.00=$27.00.
So, the amount of tip you are going to leave is $27.00.
This makes the total cost of your meal (to write on your charge slip or other payment)
$150.00 + $27.00 = $177.00.

Given that a = 6 cm and b = 5 cm,
work out the height of the triangle.
The height of the triangle is 4 cm if the a = 6 cm and b = 5 cm and applying Pythagoras theorem.
What is the Pythagoras theorem?The square of the hypotenuse in a right-angled triangle is equal to the sum of the squares of the other two sides.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We can draw a right angle triangle to find the hieght of the triangle.
Applying Pythagoras theorem.
Let h be the height:
b² = (a/2)² + h²
5² = (6/2)² + h²
5² = (3)² + h²
h = 4 cm
Thus, the height of the triangle is 4 cm if the a = 6 cm and b = 5 cm and applying Pythagoras theorem.

2(3x – 1) = 6x – 2 number of solutions
Answer: All real numbers are solutions.
Step-by-step explanation:
Let's solve your equation step-by-step.
2(3x−1)=6x−2
Step 1: Simplify both sides of the equation.
2(3x−1)=6x−2
(2)(3x)+(2)(−1)=6x+−2(Distribute)
6x+−2=6x+−2
6x−2=6x−2
Step 2: Subtract 6x from both sides.
6x−2−6x=6x−2−6x
−2=−2
Step 3: Add 2 to both sides.
−2+2=−2+2

what is the value of p so that the expession 6x+3-(8x-5) is equivalent to (px+8)?
Answer:
-2
Step-by-step explanation:
The first equation simplifies to -2x+8 so p should be replaced with -2
The value of p so that the expression 6x+3-(8x-5) is equivalent to (px+8) is, -2
What are expressions?An expression is a sentence with at least two numbers or variables having mathematical operation. Math operations can be addition, subtraction, multiplication, division.
For example, 2x+3
Given that,
An expression, 6x+3-(8x-5)
another expression, (px+8)
Value of p for which both the expressions are equivalent = ?
So now, we can compare both the expressions
⇒ 6x+3-(8x-5)
⇒ 6x+3-8x+5
⇒ -2x+8
if compare it with (px+8)
then, p = -2
Hence, the values of p is -2

In addition to the information given below in the drawing, which statement is sufficient to prove triangle STW similar to triangle XYZ?
The additional information which needed to prove triangle STW similar to triangle XYZ are SW = 15 and TW = 24
What are similar triangles?Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles. If two or more figures have the same shape, but their sizes are different, then such objects are called similar figures.
Given that, two triangles STW and XYZ, ST = 27, XY = 9, YZ = 8 and XZ = 5
We need to select a statement which will complete the proof of Δ STW ~ Δ XYZ
We know that, Similar triangles have the same corresponding angle measures and proportional side lengths.
If we consider Δ STW ~ Δ XYZ,then we get,
ST / XY = TW / YZ = SW / XZ = 3
Therefore,
SW / XZ = 3
SW / 5 = 3
SW = 15
Also,
TW / YZ = 3
TW / 8 = 3
TW = 24
Hence, the additional information which needed to prove triangle STW similar to triangle XYZ are SW = 15 and TW = 24
