Answer:
500 cm³
Step-by-step explanation:
Using the given values in the given formula, we find the volume to be ...
[tex]V=\dfrac{4}{3}\pi r^3\\\\V=\dfrac{4}{3}(3)(5\text{ cm})^3 = 4(125\text{ cm}^3) = \boxed{500\text{ cm}^3}[/tex]
The volume of the sphere is about 500 cubic centimeters.

Additional comment
The actual value of pi would add about 4.72% to this figure, bringing the estimate to about 523.6 cm³.
Step-by-step explanation:
Step 1: Formula
Solve for: Volume
Formula: V=4/3 πr^3
Explanation in words (Short Form)
- The first step is to use the formula and simplify it. So first we will use the formula which is V = 4/3 π and then divide it by 3, 3 times.
- The second step is to solve and at the end the answer will result as 523.59. Here is the full explanation and how I solved it.
V = 4/3 π r³ = 4/3 × π × 5³ = 523.59878
Answer:
V≈523.6
Full Answer: 523.59878 OR 500

He studies for 50 minutes.
Then he plays for 30 minutes.
Complete the steps below to determine what time he finishes playing.
Fadi finishes studying at 4 : 20 and he finishes playing at 4 : 50.
What is Addition?Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.
The process of doing addition is also called as finding the sum.
Given that Fadi starts studying at 3 : 30.
Length of studying was 50 minutes.
3 : 30 adding 50 minutes gives 4 : 20.
Hence he finishes studying at 4 : 20.
Fadi starts playing at 4 : 20.
Length of playing was 30 minutes.
4 : 20 adding 30 minutes gives 4 : 50.
Hence he finishes studying at 4 : 50.
Hence the end time of studying and playing is 4 : 20 and 4 : 50 respectively.

Answer: -15.36, -1.44, 0.85, 4
Step-by-step explanation:
Step 1: Evaluate (solve) all of the expressions (equations)#1: -4.8x3.2= -15.36
#2: 2 1/4+ -1 2/5
2 1/4= 2.25
-1 2/5= -1.4
2.25+-1.4
*Whenever you have a +- something, it always becomes -
2.25 - 1.4= 0.85
#3: 4.32÷-3= -1.44
#4: -2 3/5 - -12/5
2 3/5= 2.6
-1 2/5= -1.4
2.6 - -1.4
*Whenever you have 2 minuses like - -, it always becomes a +.
So 2.6 - -1.4 becomes 2.6+1.4
2.6+1.4= 4
Step 2: List from least to greatest.Okay so the numbers we have are:
-15.36, 0.85, -1.44, 4
The least number is the one farthest away from 0. This number would be -15.36, because, here's a rule to remember:
The "bigger" the negative number looks, the smaller it actualy is beacuse it is farther away from 0. For example, -29 is smaller than -1 even though it looks bigger because -29 is farther from 0. If it were positive numbers, 29 would definitely be greater though.So -15.36 is the smallest or the least.
Next, you see that -1.44 is the next in line because its the only remaining negative number and it has to be smaller than the others, which are positive.
3rd of all, i know that 0.85 comes next on the list because it is smaller than 4. It is still above 0, making it positive.
Finally, 4 is the greatest. It's bigger than 0.85, which obviously is less than 1. Now here's the list of numbers from least--> greatest:
-15.36, -1.44, 0.85, 4
Now all you have to do is put these numbers into the boxes in order. If it doesn't make sense, try putting the first 2 numbers into the first 2 boxes. By doing this you get -15.36<-1.44, which is a true statment. If you want to go further, put 0.85 in the 3rd bubble to get -1.44<0.85 which is also true. Finally, when you put 4 in the last bubble, you get 0.85<4, which is true. That's how i know my answer is correct.

[tex]\large{\boxed{ \sf x = 1, \ x = 0 }[/tex]
Explanation:[tex]\sf \Rightarrow \dfrac{x}{x-2\:}+\:\dfrac{x-1}{x+1}=\:-1[/tex]
[tex]\sf \Rightarrow \dfrac{x(x+1)+(x-1)(x-2)}{(x-2)(x+1)}=\:-1[/tex]
[tex]\sf \Rightarrow \dfrac{x^2+x+x^2-2x-x + 2}{x^2 - 2x + x - 2}=\:-1[/tex]
[tex]\sf \Rightarrow 2x^2-2x+ 2=\:-1(x^2 - 2x + x - 2)[/tex]
[tex]\sf \Rightarrow 2x^2-2x+ 2=\:-x^2 + 2x - x + 2[/tex]
[tex]\sf \Rightarrow 2x^2+x^2 -2x - x+ 2-2=0[/tex]

[tex]\sf \Rightarrow 3x = 0 , \ x - 1 = 0[/tex]
[tex]\sf \Rightarrow x = 0 , \ x =1[/tex]
Answer:
x = 0 or x = 1
Step-by-step explanation:
Given equation:
[tex]\dfrac{x}{x-2}+\dfrac{x-1}{x+1}=-1[/tex]
Multiply the two denominators to get the same denominator:
Multiply the numerator of the first fraction by the denominator of the second fraction to get the new numerator of the first fraction.
Multiply the numerator of the second fraction by the denominator of the first fraction to get the new numerator of the second fraction.
[tex]\implies \dfrac{x(x+1)}{(x-2)(x+1)}+\dfrac{(x-2)(x-1)}{(x-2)(x+1)}=-1[/tex]
Add the numerators and keep the denominator so that there is now one fraction:
[tex]\implies \dfrac{x(x+1)+(x-2)(x-1)}{(x-2)(x+1)}=-1[/tex]
Simplify the numerator by expanding the brackets:
[tex]\implies \dfrac{x^2+x+x^2-3x+2}{(x-2)(x+1)}=-1[/tex]
[tex]\implies \dfrac{2x^2-2x+2}{(x-2)(x+1)}=-1[/tex]
Simplify the denominator by expanding the brackets:
[tex]\implies \dfrac{2x^2-2x+2}{x^2-x-2}=-1[/tex]
Multiply both sides by the denominator of the left side:
[tex]\implies 2x^2-2x+2=-1(x^2-x-2)[/tex]
Simplify and move everything to the left side:
[tex]\implies 2x^2-2x+2=-x^2+x+2[/tex]
[tex]\implies 3x^2-3x=0[/tex]
Factor:
[tex]\implies 3x(x-1)=0[/tex]
Therefore:
[tex]\implies 3x=0 \implies x=0[/tex]
[tex]\implies x-1=0 \implies x=1[/tex]
Therefore, x = 0 or x = 1

The volume of the given right circular cylinder is 256ℼ cubic yards. If h, the height of the cylinder is 16 yards, what is r the radius of the base?
A. 4 yd.
B. 6 yd.
C. 12 yd.
D.16 yd.
Answer: 4 yards
Step-by-step explanation: The formula for the volume of a cylinder is Pi * Radius squared * height.
If the end result is 256pi, and the height is 16, then the radius must be 4, because 4^2 = 16, and 16*16 = 256, and 256*pi = 256pi.
Please mark as brainliest if this was helpful.
Answer:
r = 4yd (Answer A)
Step-by-step explanation:
The volume of a cylinder of radius r and height h is V = πr²h, and the applicable V value here is 256π yd³. We divide this by 16 yd to find the area of the base: 16π yd².
The base is a circle of radius r, which is to be determined:
πr² = 16π yd²
This reduces to r² = 16 yd², and so r = 4yd (Answer A)

-8
Answer: -8
Step-by-step explanation:
3+(-4)-7
Whenever you have a +(- something), it ALWAYS becomes a -
So 3+(-4)= 3-4
Now we have:
3-4-7
PEMDAS states that you must do the subtraction from left to right. So you start with the 3-4.
3-4-7
-1-7
-8
Whenever you have a negative number minus a number , the result will always be negative.
Hence, thats why the answer is -8

Answer:
(d) x = -3/4; y = -3 1/2
Step-by-step explanation:
You are asked for the coordinates of the point of intersection of the lines on the graph. This requires interpolation, because not all grid lines are marked, and the point is not on any grid line.
InterpolationThe idea of "interpolation" is figuring the value of a point that lies between points whose values are known. The answer choices here suggest that we are to interpolate to the nearest 1/4 unit. This requires that you mentally (or actually) divide the space between grid lines into 4 equal sections, and figure where the point lies relative to those divisions.
In the case of the x-coordinate, the first grid line left of the y-axis is not marked, but we notice it lies halfway between x=0 and x=-2. That means we can safely assume that the unmarked vertical grid line has a value of x=-1.
Applicationhorizontal coordinate
The location of the point of intersection of the two lines is horizontally closer to the -1 (unmarked) grid line than it is to the y-axis. Its x-value will be between -1 and 0. The answer choices tell us it is -3/4, consistent with it being about 3/4 of the distance toward -1 from 0.
x = -3/4
vertical coordinate
The location of the point of intersection of the two lines is vertically about halfway between -3 and -4. The answer choices tell us it is -3 1/2.
y = -3 1/2

f(x) = one sixteenth (x − 2)2 + 2
f(x) = one eighth (x − 2)2 − 2
f(x) = −one sixteenth (x + 2)2 − 2
Answer:
f(x)=1/16(x-2)^2+2
Step-by-step explanation:
The Equation can be written like this:
f(x) = 1/(4p)(x -h)^2 +(k-p)
where (h, k) is the focus, and p is half the distance between focus and directrix. Here, (h, k) = (2, 6) and p=(6-(-2))/2 = 4. So the equation is ...
