What is the volume of a sphere with a radius of 24.2 ft, rounded to the
nearest tenth of a cubic foot?
Answer:
V is about 59335.5 cubic feet
Step-by-step explanation:
The formula to find the volume of a sphere is V=4/3πr^3.
If the radius is 24.2, we just need to substitute numbers into the equation.
V=4/3(3.14)(24.2^3)
V=4/3(3.14)(14172.488) **Find 24.2 cubed**
V=(4*14172.488)/3*3.14
V=(56689.952)/3*3.14 **Multiply the numerator**
V=18896.65067*3.14 **Divide the numerator by the denominator**
V=59335.48309 **Multiply by the simplified pi**
V is about 59335.5 cubic feet
It's a bit long of work but I hope I was able to have helped! Good Luck!
Answer:
The volume of given sphere is 59,335.5 cubic feet
Step-by-step explanation:
Given that
Radius of sphere=r= 24.2 feet
The volume of a sphere is calculated by the formula:
[tex]V = \frac{4}{3}\pi r^3[/tex]
We can use 3.14 or 22/7 for the value of pi
Putting the values, we get
[tex]V = \frac{4}{3} * 3.14 * (24.2)^3\\= \frac{12.56}{3} * 14,172.488\\=\frac{178,006.44928}{3}\\=59,335.48309[/tex]
Rounding off to nearest tenth of cubic feet
59,335.5 cubic feet
Hence,
The volume of given sphere is 59,335.5 cubic feet

5. The 7th grade has 386 students. There are 32 more girls than boys in the grade.
How many boys are in the 7th grade?
Answer:
161 boys
Step-by-step explanation:
First you find the even amount of boys and girls out of 386
386 divided by 2 = 193
Then you subtract 32 boys and add the 32 to girls since there are 32 more girls than boys
(boys) 193 - 32 = 161
(girls) 193 + 32 = 225
So there are 161 boys and 225 girls

A study of 40 English composition professors showed that they spent, on average, 13 minutes correcting a student's term paper. The standard deviation was 2 min. a. Find and the 90% confidence interval for the mean grading time of all composition papers. < μ < b. intrepret the meaning of the confidence interval you found in part a. b. Does the confidence interval, at 90% confidence level, provide sufficient evidence that the mean time English composition professors spend on grading term papers exceeds 11 minutes? Write an appropriate inequality to justify your answer.
Answer:
a)
90% confidence interval for the mean grading time of all composition papers.
(12.47981 , 13.52019)
b)
Appropriate inequality
The interval is ( 12.47981 < μ < 13.52019)

The value of the expression 3x - y² when x = 8 and y = -2 is -12.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
3x - y²
Substitute x = 8 and y = -2
3 x 8 - 9(-2)²
24 - 9 x 4

Answer:c
Step-by-step explanation:c
The product of a number and 2 is 3 less than the quotient of a number and 5 .
Answer:
The sentence you have can be expressed in algebra (using x as 'the number'):
2x + 5 = x / 3. (We add 5 to the left side because that product is less than the right side.)
Now all you have to do is to combine the x terms on one side of equation, putting the constant on the other side of the equation, and solve for x.
or
Let the unknown number that we are solving for be x.
The product of a number and 2 means 2*x
5 less than the quotient of a number and 3 means x/3 - 5.
So,
2*x = x/3 - 5 subtract x/3 from both sides of the equation
2x - x/3 = -5 , now find the least common denominator for the left side of the equation
6x/3 - x/3 = -5
(6x - x)/3 = -5
5x/3 = -5, now multiply both sides of the equation by 3
5x = -15 now divide both sides of the equation by 5
x = - 3. So the number is -3.
Step-by-step explanation:
Building an equation and solving for the number, it is found that the number is [tex]x = -\frac{3}{2}[/tex]
----------------------
The number can be called x.Product of a number and 2 is [tex]2x[/tex]3 less than the quotient of a number and 5 is: [tex]\frac{x}{5} - 3[/tex]Equal, thus:
[tex]2x = \frac{x}{5} - 3[/tex]
Multiplying everything by 5:
[tex]10x = x - 15[/tex]
[tex]9x = -15[/tex]
[tex]x = -\frac{15}{9}[/tex]
[tex]x = -\frac{3}{2}[/tex]

Answer:
B. Ramp with a length of 200 feet and a height of 50 feet.
Step-by-step explanation:
When it comes to slope, y is on top and x is on the bottom. The fraction gives us a ratio. In this case, the x is 4 times bigger than the y. In this instance, the length of the ramp is 4 times bigger than the height of the ramp.
You check by seeing if they reduce to 1/4:
50/200 = 1/4

Answer:
x=17
Step-by-step explanation:
The exterior angle theorem states that one exterior angle of a triangle is equal to the sum of its opposite interior angles. Knowing this, we can set up the following equation:
(8x-11)=(5x)+(2x+6)
Open up the parentheses
8x-11=5x+2x+6
8x-11=7x+6
Add 11 to both sides
8x-11+11=7x+6+11
8x=7x+17
Subtract both sides by 7x
8x-7x=7x+17-7x
x=17
