Answer:
The diameter is 7.6 cm
Step-by-step explanation:
Mathematically, the volume of a cylinder can be calculated using the formula;
V = pi * r^2 * h
From the question;
V = 900
r = ?
h = 20
Substituting these values
900 = 3.142 * r^2 * 20
r^2 = (900)/(3.142 * 20)
r^2 = 14.32
r = √14.32
r = 3.78 cm
Mathematically, the diameter is 2 times the radius
We have this as;
2 * 3.78 = 7.6 cm
tent: If a function f has an inverse and f(-3) = 6, then f-1(6)
The value of [tex]f^{-1}(6)[/tex] is [tex]-3[/tex].
Given:
The function [tex]f[/tex] has an inverse and [tex]f(-3)=6[/tex].
To find:
The value of [tex]f^{-1}(6)[/tex].
Explanation:
If a point [tex](a,b)[/tex] lies on the function [tex]f(x)[/tex], then the point [tex](b,a)[/tex] must lies on the inverse function [tex]f^{-1}(x)[/tex].
According to the given value [tex]f(-3)=6[/tex], the point [tex](-3,6)[/tex] lies on the function [tex]f(x)[/tex]. So, the point [tex](6,-3)[/tex] must be lies on [tex]f^{-1}(x)[/tex].
[tex]f^{-1}(6)=-3[/tex]
Therefore, the value of [tex]f^{-1}(6)[/tex] is [tex]-3[/tex].

Step-by-step explanation:
Find the values of k so that each remainder is three.
10. (x^2+ 5x + 7) = (x + k)
Answer:
[tex]k=1\text{ or } k=4[/tex]
Step-by-step explanation:
We can use the Polynomial Remainder Theorem. It states that if we divide a polynomial P(x) by a binomial in the form (x - a), then our remainder will be P(a).
We are dividing:
[tex](x^2+5x+7)\div(x+k)[/tex]
So, a polynomial by a binomial factor.
Our factor is (x + k) or (x - (-k)). Using the form (x - a), our a = -k.
We want our remainder to be 3. So, P(a)=P(-k)=3.
Therefore:
[tex](-k)^2+5(-k)+7=3[/tex]
Simplify:
[tex]k^2-5k+7=3[/tex]
Solve for k. Subtract 3 from both sides:
[tex]k^2-5k+4=0[/tex]
Factor:
[tex](k-1)(k-4)=0[/tex]
Zero Product Property:
[tex]k-1=0\text{ or } k-4=0[/tex]
Solve:
[tex]k=1\text{ or } k=4[/tex]
So, either of the two expressions:
[tex](x^2+5x+7)\div(x+1)\text{ or } (x^2+5x+7)\div(x+4)[/tex]
Will yield 3 as the remainder.

Given:
32 and 28 are the two numbers.
To find:
(a) The GCF of 32 and 28.
(b) Using the GCF, find the factor of (32-28).
Solution:
(a)
The factor forms of the given numbers are:
[tex]32=2\times 2\times 2\times 2\times 2[/tex]
[tex]28=2\times 2\times 7[/tex]
It is clear that, 2 and 2 are the common factors in both.
[tex]GCF(32,28)=2\times 2[/tex]
[tex]GCF(32,28)=4[/tex]
Hence, the GCF of 32 and 28 is 4.
(b)
Using the GCF we need to find the factor of (32-28).
[tex]32-28=4\times 8-4\times 7[/tex]
Taking out the GCF, we get
[tex]32-28=4\times (8-7)[/tex]
Hence, [tex]32-28=4\times (8-7)[/tex].

I need to find out what makes m ll n I’m in geometry and this is big ideas please help if can
============================================
Explanation:
On that diagram, the unmarked angle above the (6x-8) is equal to (5x+12). This is because the unmarked angle and the angle marked with (5x+12) are corresponding angles. Corresponding angles must be congruent if you want line m to be parallel to line n.
From here we add up (5x+12) and (6x-8) and set that sum equal to 180. Solve for x
We get the following:
(5x+12)+(6x-8) = 180
5x+12+6x-8 = 180
(5x+6x)+(12-8) = 180
11x+4 = 180
11x = 180-4
11x = 176
x = 176/11
x = 16

Yes, this is correct
WE can multiply 1*5 and 4*5 to get 5 to 20
19
Wrong
3 to 11, 1 to 3 isn't correct
For example, if we were to divide 3 by 3 to get one, 11/3 is 2. (6)
So, no
20
2/3 is 2 to 3
14/21 is 14 to 21
If we multiply 2*7 and 3*7, we get 14 to 21
21 25 to 30 is equal to 35 to 42

Answer:
4
Step-by-step explanation:
Given that :
Total fraction of paint Carin has = 2/3 bottle
Fraction used to paint a model airplane = 1/6
Number of model. Airplanes 2/3 of a bottle could paint ;
Total fraction of paint / fraction used to paint a model airplane
(2/3) ÷ (1/6)
2/3 * 6/1
= 12 / 3
= 4 model airplanes

Answer:
part 1:
see in the picture, E is the centre of the kite
1) AC = 2.EC = 40
2) CD = sqrt( ED² + EC² ) = sqrt(21² + 20²) = 29
3) ABE = 90⁰ - 51⁰ = 39⁰
4) BCE = BAE = 51⁰
part 2:
we have:
3x + 7 = (3x - 1 + 8x)/ 2
<=> 3x + 7 = 5.5x - 0.5
<=> 2.5x = 7.5
<=> x = 3
5) with x = 3 => UV = 3.3 - 1 = 9 - 1 = 8
6) XY = 3.3 + 7 = 9 + 7 = 16
7) TW = 8.3 = 24
9) the width of the base is x (x > 0)
we have:
28.5 = (x + 25)/2
<=> x + 25 = 57
<=> x = 32
