Answer:
r ≈ 7.963 cm
Step-by-step explanation:
Given the following dimensions of a cylinder:
Volume (V) = 3785 cm³
Height (h) = 19 cm
In order to find the value of the radius, it is necessary to determine the formula for finding the radius of a cylinder.
The formula for finding the volume of a cylinder is: V = πr ²h
To isolate the radius, start by dividing both sides by π × h :
[tex]\mathsf{\frac{V} {\pi\times\:h}\:=\:\frac{\pi\:r^{2}\:h} {\pi\times\:h}}[/tex]
[tex]\mathsf{\frac{V} {\pi\times\:h}\:=\:r^{2}}[/tex]
Next, take the square root of both sides to isolate r :
[tex]\mathsf{\sqrt{\frac{V}{\pi\times\:h}} = \sqrt{r^{2}}}[/tex]
[tex]\mathsf{\:r\:=\:\sqrt{\frac{V}{\pi\times\:h}}}[/tex]
Now, we can finally substitute the given values into the formula for radius, r:
[tex]\mathsf{\:r\:=\:\sqrt{\frac{3785}{\pi\times\:19}}}[/tex]
r ≈ 7.963 cm
Therefore, the radius of the cylinder is 7.963 cm.

Translate the following phrase into an inequality:
"A number n minus 3.5 is less than or equal to 4."
PLEASE HELP I HAVE 6 MATH MISSING ASSIGNMENTS, I HATE HIGH SCHOOL
Answer:
The term "at least" means the lowest number you can have. In other words, you cannot have a number less than that point. So we use the greater than or equal symbol.
x - 3 ≥ - 5
Add 3 on both sides of the inequality.
x ≥ -2
x is any number greater than or equal to -2.
If the term was "at most", then that is the highest number you can have, and you can go no higher than that. In this case, we would have used the less than or equal to symbol.
These terms are important to understand when working with inequalities.
The value of the inequality form of the phrase "A number n minus 3.5 is less than or equal to 4." is (n - 3.5) ≤ 4 .
Used the concept of inequality that states,
A relation by which we can compare two or more mathematical expressions is called an inequality.
Given that;
The phrase is,
"A number n minus 3.5 is less than or equal to 4."
Now it can be written in inequality form as,
(n - 3.5) ≤ 4
Therefore, the inequality is,
(n - 3.5) ≤ 4

put the polynomial in standard form -4b+7b2+1
Answer:
[tex]7b^2-4b+1[/tex]
Reasoning:
A polynomial is said to be in its standard form, if it is expressed in such a way that the term with the highest degree is placed first, followed by the term which has the next highest degree, and so on.
Thus, this will be the polynomial in standard form:

IDENTIFY A PAIR OF SEGMENTS THAT ARE MARKED PERPENDICULAR TO EACH OTHER.
WILL GIVE BRAINLIEST. PLEASE HELP.
Answer:
AB is perpendicular to IB
A pair of segment that are marked perpendicular to each other are JC and CD.
As per the figure given,
∠JCD = 90°
In geometry, when it's stated that angle JCD is 90°, it means that angle JCD is a right angle. When two line segments or rays intersect to form a right angle, it indicates that they are perpendicular to each other.
In the context of the figure given, JC is a line segment , and CD is another line segment. The fact that angle JCD is a right angle (90°) tells that JC is perpendicular to CD.
Hence, as angle JCD is given as 90°, it establishes that JC is perpendicular to CD in the context of the figure given.

can someone please help me!! this assignment is due at 11:59 I need this done
Answer:
Step-by-step explanation:
Tan (theta) = opposite / adjacent
theta = 60 degrees
opposite = 15
adjacent = opposite / Tan(theta)
adjacent = 15 / tan(60)
tan(60) = sqrt(3)
sqrt(3) = 1.732
adjacent = 15 /1.732
answer: adjacent = 8.6603
What is (n+9) - (2-2n)
Answer:
Simplifying
(n + 9) + -1(2 + -2n) = 0
Reorder the terms:
(9 + n) + -1(2 + -2n) = 0
Remove parenthesis around (9 + n)
9 + n + -1(2 + -2n) = 0
9 + n + (2 * -1 + -2n * -1) = 0
9 + n + (-2 + 2n) = 0
Reorder the terms:
9 + -2 + n + 2n = 0
Combine like terms: 9 + -2 = 7
7 + n + 2n = 0
Combine like terms: n + 2n = 3n
7 + 3n = 0
Solving
7 + 3n = 0
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-7' to each side of the equation.
7 + -7 + 3n = 0 + -7
Combine like terms: 7 + -7 = 0
0 + 3n = 0 + -7
3n = 0 + -7
Combine like terms: 0 + -7 = -7
3n = -7
Divide each side by '3'.
n = -2.333333333
Simplifying
n = -2.333333333

Answer: i think its A
Step-by-step explanation:
Let's say that a is 8, b is 17, and c is x,
Maximum:
a + b > c
8 + 17 >c
c < 25
Minimum:
b + c > a
17 + c > 8
c > -9
(As it cannot be negative, we will call this 9.)
So, our answer is D as c, x, must be less than 25 and greater than 9.
