A sphere has a volume of approximately 24,416.64 cubic inches (using 3.14 for ).
The diameter of the sphere is ___ inches.
Answers
Answer:
diameter = 36 in.
Step-by-step explanation:
V = 4π r^3/3
24416.64 = (4(3.14) r^3)/3
73249.92 = 12.56 r^3
r^3 = 5832
r = cube root of 5832 = 18
diameter = 36 in.

Actually Welcome to the concept of areas,
we know that, area of rectangle = length * width,
here, length = x-2 and width = x-1
hence, area = (x-2) (x-1)
==> area = x^2 -x -2x +2
==> Area = x^2 - 3x + 2
hence the Option D.) is correct

i hope you have a great day :)
Answer:
10 and 2
Step-by-step explanation:
a + b = 12
a - b = 8
let 'a' = 8 + b
substitute:
8 + b + b = 12
2b + 8 = 12
2b = 4
b = 2
a must be 10 then

Identify the slope and the y-intercept of the following equation 1/2x - 1 = y
b =
m =
uto: Which is the “first point” given, the slope or the y-intercept ?
Answers
Answer:
see below
Step-by-step explanation:
Our equation is y = 1/2x - 1. This mirrors our standard linear parent function of y = mx + b.
m is the slope and b is the y-intercept.
From this, we can see that
m = 1/2
and
b = -1.
The first point given is the y-intercept because with y-intercepts, we know the coordinates right away. A y-intercept's coordinates will always have an x-value of 0. This allows it to lie on the y-axis, hence the name. Our y-value of the coordinates is given with the b value of the equation. Therefore, by simply looking at the end of the equation, we know our first point.
Hope this helps!

please helpppppp asap (triangle inequality theorem) show the work
Answers
Answer:
a - yes
b - no
Step-by-step explanation:
triangle inequality theorem - the sum of any 2 sides of a triangle must be greater than the measure of the third side
For a
5 + 4 must be greater than 7 for the set to be measures of the sides in a triangle
5 + 4 = 9
9 is greater than 7 therefore 4,5, and 7 can be measures of the sides in a triangle
For b
3 + 2 must be greater than 6 in order for the set to be measures of the sides in a triangle
3 + 2 = 5
5 is less than 6 therefore 2,3 and 6 can not be measures of the sides in a triangle
visitors spend 1/3 of their time waiting in line for rides. Of the santos family spends 53/4 hours at the park how long do they wait in line
Answers
Answer: 1 11/12 hours
Step-by-step explanation:
Since visitors spend 1/3 of their time waiting in line for rides and the Santos family spends 5¾hours at the park.
The tune spent waiting in line will be calculated by multiplying ⅓ by 5¾. This will be:
= ⅓ × 5¾
= ⅓ × 23/4
= 23/12
= 1 11/12 hours
Therefore, they'll wait in the park for 1 11/12 hours

Isaac has a points card for a movie theater. He receives 45 rewards points just for signing up. He earns 11.5 points for each visit to the movie theater. He needs 160 points for a free movie ticket.
Answers
Answer: 10 visit
Step-by-step explanation:
Given
45 Points earned by signing up
11.5 points earned for each visit to the theatre
160 points are needed for a movie ticket
Suppose, after x visit he gets enough points to buy a movie ticket
[tex]\therefore 160=45+11.5x\\\Rightarrow 115=11.5x\\\Rightarrow x=10[/tex]
So, after 10th visit, he earns a movie ticket

S = 2πr(r + h)S₁ = 2π*4*(4 + 5) = 72π in²S₂ = 2π*12*(12 + 5) = 408π in²The difference is:
S₂ - S₁ = 408π - 72π = 336π in²A cylinder has a radius of 4 inches and a height of 5 inches. If the radius of the cylinder is tripled and the height remains the same to create a new cylinder, what will be the difference in the surface areas of the two cylinders ? Answer in terms of Pi.
Answer:-Given:-A cylinder has a radius of 4 inches and a height of 5 inches.
To Find:-If the radius of the cylinder is tripled and the height remains the same to create a new cylinder, what will be the difference in the surface areas of the two cylinders ?
Solution:-Let in case of 1st cylinder,[tex] \bullet [/tex] Radius [tex] (r_1) [/tex] is 4 inches
[tex] \bullet [/tex] Height is 5 inches
And in case of 2nd cylinder,[tex] \bullet [/tex] Radius [tex] (r_2) [/tex] is 3 × 4 = 12 inches [as in the question it is given that the radius of the cylinder is tripled]
[tex] \bullet [/tex] Height is 5 inches
Now,
Surface area [tex] (s_1) [/tex] of 1st cylinder
is 2πr(r + h) = 2π × 4(4 + 5)
= 8π(9)
= 72π sq inches
Surface area [tex] (s_2) [/tex] of 2nd cylinder
is 2πr(r + h) = 2π × 12(12 + 5)
= 24π(17)
= 408π sq inches
[tex] \therefore [/tex] The difference in the surface areas of the two cylinders is = [tex] (s_2 \: - \: s_1) [/tex] = (408π - 72π) = 336π sq inches
The difference in the surface areas of the two cylinders is 336π sq inches. [Answer]A man's salary is increased by $925 to $1036. Find the percentage increase. What would have been his new salary if the increase had been 16%
Answers
Answer:
See the solutions below
Step-by-step explanation:
Initial Salary= $925
Final salary= $1036
% increase= Change/initial *100
substitute
% increase= 1036-925/925 *100
% increase=111/925 *100
% increase=0.12 *100
% increase=12%
2. Let us find 16% of $925
=16/100*925
=0.16*925
=$148
Hence the salary would have been
=148+925
=$1073

Step-by-step explanation:
340/45 = 7 5/9
Answer:
7.6 pages
Step-by-step explanation:
Okie, so this is a standard unit rate problem, so what you're going to do is divide the number of whatever, in this case, pages, by the time, so:
340 ÷ 45 = 7.6 (rounded)
So you read 7.5 pages per minute
