V = 1/3 pi r^2 h
7065 = 1/3 * 3.14 * 30 * r^2
r^2 = 7065 / (1/3 * 3.14 * 30)
r^2 = 7065 / 31.4 = 225
r = sqrt 225 = 15.

what are the y-intercepts to graph the equation-4x - 3y = 36
Answer:
Y-Int = -12
Step-by-step explanation:
First, I would change the equation to slope intercept form:
-3y = 36 + 4x
3y = -36 - 4x
y = -12-4/3x
y = -4/3x - 12
-12 is the y-intercepts to graph the equation-4x - 3y = 36
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The given equation is -4x-3y=36
Now let us convert the given equation to slope intercept form y=mx+b
where m is the slope and b is the y intercept
Isolate the term y
-3y=36+4x
Divide both sides by 3
-y=36/3+4/3x
Multiply both sides by -
y=-12-4/3x
y=-4/3x-12
Slope is -4/3 and y intercept is -12
Hence, -12 is the y-intercepts to graph the equation-4x - 3y = 36

Determine whether the expression is a polynomial. If it is a polynomial, find the degree
and determine whether it is a monomial, binomial, or trinomial.
3y^2 – 2
Answer:
This expression is a polynomial. The largest exponent is 2, therefore, it is in the quadratic degree. It is a binomial because it has two parts: 3y² and -2.
find th length of size ab give your answer to 3 significant figures
Answer: 8.856cm
Step-by-step explanation:
To solve the question, we will use the formula:
Sin 41° = opposite / hypothenuse
0.656 = opposite / hypotenuse
0.656 = AB / 13.5
Cross. Multiply
AB = 13.5 × 0.656
AB = 8.856cm

PLSS HELP the length of a rectangle is 3 meters greater than 2 times the width the perimeter of a rectangle is 30 m what is the length of the rectangle
Answer:
Width: 4 meters. Length: 11 meters
Step-by-step explanation:
If you do it correctly, the length should be 3 more greater than 4*2. 4*2= 8 +3= 11. Your perimeter= 30 meters. 11+11 accounting for both long sides of the rectangle= 22. Accounting for both sides of the width, so 4*2=8 + our 22= 30 meters. Yw.
The length of the rectangle width 4 meters and length 11 meters.
If you do it correctly,
The length should be 3 more greater than
What is the perimeter of a rectangle?
P=2(l+w)
L= Length
W = Width
4*2. 4*2= 8 +3= 11.
Your perimeter= 30 meters.
11+11 accounting for both long sides of the rectangle= 22.
Accounting for both sides of the width,
So 4*2=8 + our 22= 30 meters.
Therefore we get the length of a rectangle is 11 meters.

Children 12 and under eat free at a local restaurant. If x represents age, write an inequality to represent people who do not get a discount.
Answer:
12 ≤ x
Explanation:
Kids 12 and under, meaning that the age of someone who enters the restaurant has to be less than or equal to 12 to eat free
The inequality which represents the age of the people who do not get the discount is x > 12.
What is Linear Inequalities?Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.
Given that,
Children 12 and under eat free at a local restaurant.
Let x represents the age of the people.
Since the children who are 12 and under will get the discount, the age of the people who do not get the discount is the people with age greater than 12.
That is the inequality representing this situation is,
x > 12
Hence the required inequality is x > 12.

About 0.2of all the students in the fifth grade are boys. If the fifth grade has 75 students, how many of the students are ?
Answer:
15 boys
Step-by-step explanation:
About 0.2of all the students in the fifth grade are boys. If the fifth grade has 75 students, how many of the students are boys?
The number of boys can be calculated as:
0.2 × Number of fifth grade students
Number of fifth grade students = 75 students
Therefore,
The number of boys =
0.2 × 75 students = 15
The number of boys = 15 boys
