A cylinder has a diameter of 10 inches in the height four times the radius what is the volume
Answer:
500π in^3
Step-by-step explanation:
The radius is half the diameter, so the radius is 5 in. Since the height is four times that, the height is 20 in.
The equation for the volume of a cylinder is:
[tex]V = \pi r^{2}h[/tex]
We can plug in the radius and height:
[tex]V = \pi \times (5)^{2} \times 20\\V = \pi \times 25 \times 20\\V = 500\pi in^{3}[/tex]
Pippa has a box containing n pens.
there are only black pens and red pens in the box.
the number of black pens in the box is 3 more than the number of red pens.
pippa is going to take at random 2 pens from the box.
the probability that she will take a black pen followed by a red pen is
9
35
find the possible values of n.
show clear algebraic working.
The possible values of N from the given probability parameters is; N equals 15 or 21
How to Solve Algebra Problems?We are told that;
Number of pens in the box = N
Let the number of red pens be x
Thus; number of black pens = x + 3
Thus;
x + x + 3 = N
x = (N - 3)/2
The probability that she will take a black pen followed by a red pen is;
P(she will take a black pen followed by a red pen) = (x + 3)/N * x/(N - 1)
Plugging in he relevant values and solving for N gives ;
Solving for N gives N equals 15 or 21

B.) The probability that she will NOT randomly take out two grapefruits in a row,
Probability = 1 - (4/12)² = 0.8264 = 0.8889
C.) The probability that she will NOT randomly take out two apples in a row,
Probability = 1 - (3/12)² = 0.8264 = 0.9375

(3+13-10)+14÷2+4 how do you solve this ?
Answer: 17
Step-by-step explanation:
Don't forget about PEMDAS. (parentheses, exponents, multiplication, division, addition, subtraction)
Start with parentheses
(3+13-10)... 13+3= 16, 16-10=6 ...
so (3+13-10)=6
Now we have...
6 + 14 / 2 + 4
No exponents so we go on.
no multiplication so we go on
Now division...
14 / 2 = 7 because 7 x 2 = 14
Now we have...
6 + 7 + 4
now we do addition, addition is commutative so you can add it in any order you want
6 + 7 = 13, 13 + 4 = 17
therefore, the answer is 17

Danielle is trying to solve the equation [tex]8^x=\frac{1}{64}[/tex]. Explain in detail how Danielle should solve this problem. Then solve it step by step showing all your work and tell Danielle what the answer should be.
Answer:
x=-2
Step-by-step explanation:
Given equation:
8^x= 1/64
Ensure both sides of the equation are in power format by changing 1/64
1/64 = 64^-1
8^x = 64^-1
2^3(x) = 2^6(-1)
The bases will cancel out each other
3(x) = 6(-1)
3x = -6
x = -6/3
x = -2
Check
8^x = 1/64
x = -2
8^-2
= 1/8²
= 1/8*8
= 1/64
James defines a circle as the set of all the points equidistant from a given point. His statement is not precise enough because he should specify that.
A circle has a center, radius, diameter and points in a plane. Depending on the context, the definition of a circle must contain at least one of the following terms:
Center
Radius
Diameter
Points in a plane
The complete question is as follows:-
James defines a circle as "the set of all the points equidistant from a given point." His statement is not precise enough
because he should specify that
A circle includes its diameter
The set of points is in a plane
A circle includes its radius
The set of points is collinear
What is a circle?A circle is a two-dimensional geometry on the plane having a center point and the circular line is drawn equidistant from the center point.
Based on James' definition of a circle, he needed to specify that the points are in a plane (option c).
As presented in his definition "the set of all the points" can be interpreted in several ways. Some of which are:
the set of points on a line
the set of points in a plane
the set of points in a region
Etc
Of these numerous possible interpretations, James should have specified that the set of points is in a plane

Since the paper representing her desk is 1 1/4 inches by 2 1/4 inches, the actual dimensions of her desk are D: 2 ¹/₂ ft by 4 ¹/₂ ft
To answer the question, we need to know what scale is
What is a scale?A scale is the ratio of two dimension and it is given on a scale drawing.
Given that Chelsea makes a scale drawing of the room and cuts out pieces of paper to represent her furniture, and the paper representing her desk is 1 1/4 inches by 2 1/4 inches.
Since on the scale, we have 1/2 in = 1 foot ⇒ 1 in = 2 ft
Actual dimensions of deskSo, the actual dimensions of her desk are
1 ¹/₄ in by 2 ¹/₄ in = 5/4 in by 9/4 in
= 5/4 × 1 in by 9/4 × 1 in
= 5/4 × 2 ft by 9/4 × 2 ft

Write an equation of the parabola in vertex form that passes through ( 3 , -2 ) and has a vertex of ( 5,8 )
Answer:
Parabola in vertex form: y = a(x - h)2 + k
Vertex: (h, k) = (3, 2) and (x, y) = (13, 8)
y = a(x - h)2 + k
y = a(x - 3)2 + 2 <== with substitution (h, k) = (3, 2)
8 = a(13 - 3)2 + 2 <== with substitution (x, y) = (13, 8)
8 = a(10)2 + 2
100a = 8 - 2 ==> 100a = 6 ==> a = 6/100 ==> a = 3/50
Parabola in vertex form: y = a(x - h)2 + k
y = (3/50)(x - 3)2 + 2 (Final Answer - Parabola in vertex form)
Step-by-step explanation:
Answer:
Hi,
Step-by-step explanation:
Parabola has the equation:
y=k*(x-5)²+8
if x=3, y=-2: -2=k*(-2)²+8 ==> 4k=-10==> k=-5/2
So y=-5/2(x-5)²+8
