Find the volume of a right circular cone that has a height of 13 in and a base with a
circumference of 5.1 in. Round your answer to the nearest tenth of a cubic inch.
Answer:
Step-by-step explanation:
the formula for finding the volume of a cone would be V= 3.14 r sqaured * h/3
so plug that in and it would be 3.14(5.1) sqaured * 13/3
3.14 is the formula of pie which is in the formula for finding the volume of
5.1*5.1= 26.01
3.14* 26.01= 81.67
13/3= 4.34
81.67* 4.34= 354.45
The volume of a right circular cone that has a height of 13 in and a base with a circumference of 5.1 inches is 8.97824.
Calculation of the volume of right circular cone:
Since
We know that
Volume = [tex]\pi r^2 \frac{h}{3}[/tex]
Since the circumference is 5.1 inches
So here the radius be like
Circumference = [tex]2\pi r[/tex]
5.1 = 2(3.14) r
r = 0.8121
Now the volume should be
[tex]= 3.14 \times (0.8121)^2 \frac{13}{3}[/tex]
= 8.97824
Hence, The volume of a right circular cone that has a height of 13 in and a base with a circumference of 5.1 inches is 8.97824.

Which of the following inequalities represents the problem and could be solved to find the maximum number of students,
x, who could attend the movie?
The maximum number of students, x, who could attend the movie are,
⇒ x ≈ 21
What is Inequality?A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
A teacher can spend as much as $125.00 to take students to a movie.
And, A movie theater charges a $10.00 group fee and $5.50 per ticket.
Let maximum number of students, x, who could attend the movie = x
Hence, We can formulate;
5.50x + 10 ≤ 125
Solve for x;
5.50x ≤ 125 - 10
5.50x ≤ 115
x ≤ 115 / 5.50
x ≤ 20.90
x ≈ 21
Thus, The maximum number of students, x, who could attend the movie are,
⇒ x ≈ 21

Answer:
1. see the first attachment for a graph; quadrants I, II, III; vertex (-3, -4); x-intercepts -5, -1; graph is dashed line, shaded inside the parabola, which opens up
2. see the second attachment for a graph; all quadrants; vertex (1, 2); x-intercepts 1±√2; graph is a solid line, shaded outside the parabola, which opens down; (-7, 0) is a solution
Step-by-step explanation:
1. The boundary expression is in vertex form, so the vertex can be read directly.
y = (x -h)^2 +k . . . . . . parabola with vertex (h, k)
y > (x +3)^2 -4 . . . . . (h, k) = (-3, -4)
The leading coefficient is +1, a positive number, so the parabola opens up. The relation is y > ( ), so values of y above the dashed line will be shaded. Those values are inside the parabola. The points (0, 0) and (-7, 0) are not in the shaded area, so are not solutions.
__
2. Again, the boundary expression is in vertex form, so the vertex can be read directly.
y ≥ -(x -1)^2 +2 . . . . . (h, k) = (1, 2)
The x-intercepts are found by solving for x when y=0:
0 = -(x -1)^2 +2
x -1 = ±√2
x = 1±√2
The leading coefficient is -1, so the parabola opens downward. The relation is y ≥ ( ), so y-values above the solid line will be shaded. Those values are outside the parabola. Point (0, 0) is not a solution. Point (-7, 0) is a solution.
_____
Additional comment
As with the graph of any inequality, the boundary line is solid when the "or equal to" case is part of the relation. If the relation is strictly "greater than" or "less than", then the boundary line is dashed.

The height of a golf ball hit in the air is modeled by the equation ℎ(t)=−16t2 + 48t, where ℎ(t) represents
the height, in feet, and t represents the number of seconds that have passed since the ball was hit.
Complete the statement about the function for ℎ(2)=32
If ℎ(2)=32 , then the ball reached a height of _________ feet after _________ seconds.
Answer:
16 feet, 2 seconds
Step-by-step explanation:
as the problem state that h= height and t = time, to get the h you need to isolate it so we divide it by 2 and we get 16 feet. The 2 are already in the problem h(2).

So we have :

Both sides plus 2ab :

Step-by-step explanation:
the question tells you that the angle CBD is 90°.
so, that means that angle DBE and angle CBE add up to 90.
using this, you can make the following equation:
2x - 1 + 5x - 42 = 90
2x + 5x + -43 = 90
7x - 43 = 90
add 43 to both sides
7x = 90 + 43
7x = 133
x = 133/7
x = 19

In 2010, the average finishing time for marathons across the US was approximately 278 minutes, with a standard deviation of approximately 63 minutes. What finishing time defines the fastest 7.93% of runners?
Answer:
336 minutes
Step-by-step explanation:
Mean finishing time: 278 minutes
Standard Deviation: 63 minutes
Confidence interval: [278 - 63] , [278 + 63] = [215 , 341] minutes
What finishing time defines the fastest 7.93% of runners?
This means the 7.93% of time closest to the upper limit of 341 minutes
341 - 215 ≡ 63 × 2 = 126
7.93% of 126 = 0.0793 × 126 = 9.9918
341 - 9.9918 = 331.0082
Hence the finishing time that defines the fastest 7.93% of runners has an interval of [331 , 341] minutes with a mean or average of 336.0041 ≅ 336 minutes

Answer:
1) Expression
2) Equation
3) Equation
4) Expression
Step-by-step explanation:
An equation always contains an equal sign, so in this case, if it doesn't contain an equal sign, it's an expression.
For 2 and 3, you can see that there is an equal sign, but for 1 and 4, there is not.
Therefore, 1 and 4 are expressions and 2 and 3 are equations.
