A sphere with a radius of 3 cm has the same volume as a cone with a radius of 6 cm. What is the height of the cone?!
2 cm
3 cm
4 cm
5 cm
Answer:
Step-by-step explanation:
VC = (1/3)·pi·r2·h
VC = volume of a cone
r = radius of base of cone = 6 cm
h = height
VC = (1/3)·pi·62·h
VC = 12·pi·h
VS = (4/3)·pi·r3
VS = volume of a sphere
r = radius of base of sphere = 3 cm
VS = (4/3)·pi·33
VS = 36·pi
Since the volume of the cone and the sphere are equal:
VC = VS
12·pi·h = 36·pi
Solve for h.

Maya is working two summer jobs, making $7 per hour babysitting and $11 per hour landscaping. Last week Maya earned a total of $96 and worked 3 times as many hours babysitting as she worked hours landscaping. Determine the number of hours Maya worked babysitting last week and the number of hours she worked landscaping last week.
The number of hours Maya worked babysitting and landscaping last week is 2.4 hours and 7.2 hours respectively
Given:
Earnings for babysitting = $7
my Earnings for landscaping = $11
Total earnings = $96
Iet
number of hours babysitting = x
number of hours landscaping = y
y = 3 × x
y = 3x (1)
y = 3x (1)7x + 11y = 96 (2)
substitute (1) into (2)
7x + 11y = 96 (2)
7x + 11(3x) = 96
7x + 33x = 96
40x = 96
x = 96/40
x = 2.4 hours
substitute x = 2.4 into (1)
y = 3x (1)
y = 3(2.4)
y = 7.2 hours
Therefore, the number of hours Maya worked babysitting and landscaping last week is 2.4 hours and 7.2 hours respectively

7 - 9 = 7+(-9)
Add.
The required sum of 7 and -9 is -2. Adding a negative number to a positive number results in a negative sum.
When adding the numbers 7 and -9, we follow the rules of addition with positive and negative numbers. To add a positive number and a negative number, we can think of it as subtraction. In this case, we have 7 + (-9), which is the same as 7 - 9.
To perform the addition, we subtract 9 from 7:
7 - 9 = -2
Therefore, the sum of 7 and -9 is -2. Adding a negative number to a positive number results in a negative sum. In this case, subtracting 9 from 7 gives us -2.

What is the value of x? Enter your answer in the box.
(3x + 50)
(6x – 10)
x=
Answer:
First of all (3x + 50) is equal to (6x - 10) so (3x + 50) = (6x - 10) 3x + 50 = 6x - 10 60 = 3x 20 = x
Step-by-step explanation:
Answer:
Step-by-step explanation:
(3x + 50)(6x + -10) = 0
Reorder the terms:
(50 + 3x)(6x + -10) = 0
Reorder the terms:
(50 + 3x)(-10 + 6x) = 0
Multiply (50 + 3x) * (-10 + 6x)
(50(-10 + 6x) + 3x * (-10 + 6x)) = 0
((-10 * 50 + 6x * 50) + 3x * (-10 + 6x)) = 0
((-500 + 300x) + 3x * (-10 + 6x)) = 0
(-500 + 300x + (-10 * 3x + 6x * 3x)) = 0
(-500 + 300x + (-30x + 18x2)) = 0
Combine like terms: 300x + -30x = 270x
(-500 + 270x + 18x2) = 0
Solving
-500 + 270x + 18x2 = 0
Solving for variable 'x'.

What is the GCF of 5 , 6 , and 8
Answer:
The GCF of 5, 6, and 8 would be 1.
Step-by-step explanation:
To find the GCF (Greatest Common Factor) of any amount on numbers, you would find the factors of the numbers and find which is the greatest one that they have in common.
To find the GCF of 5, 6, and 8, we must first find the factors of 5, 6, and 8.
Factors of 5: 1, 5
Factors of 6: 1, 2, 3, 6
Factors of 8: 1, 2, 4, 8
Now we found the factors of 5, 6, and 8. to find the GCF, we must now find which factors they have in common.
The factors 5, 6, and 8 have in common is 1. Since they have no other factors in common, 1 would be the GCF.
The GCF of 5, 6, and 8 would be 1.
I hope this helps. :)
Final answer:
The Greatest Common Factor (GCF) of the numbers 5, 6, and 8 is 1, as it is the only common factor among all the numbers.
Explanation:
The Greatest Common Factor (GCF) of the numbers 5, 6, and 8 is found by determining the largest number that divides each of the given numbers without leaving a remainder. To find the GCF, we can list the factors of each number:
Factors of 5: 1, 5Factors of 6: 1, 2, 3, 6Factors of 8: 1, 2, 4, 8Looking at the factors, 1 is the only number that is common to all three, making it the GCF.
Hence, the GCF of 5, 6, and 8 is 1. This methodically derived GCF encapsulates the common factor that unifies the numerical trio.

A magazine contains thirteen pages. You
open to a random page. The page number
is two or ten.
If a magazine contains thirteen pages, it means that the pages are numbered from 1 to 13. When you open the magazine to a random page, there are two possibilities for the page number: it can either be two or ten.
Page number in a magazine
In the context of a magazine, the page number refers to the physical numbering of the pages within the publication.
The page number is typically printed near the top or bottom of each page, allowing readers to navigate through the content.
In this case, if you randomly open the magazine to page two, you will find the content printed on that page. Similarly, if you randomly open the magazine to page ten, you will find different content printed on that page.
A cone has a volume V, radius r, and a height of 12 cm. A cone has the same height and 1/3 of the radius of the original cone. Write an expression for its volume.
Answer:
[tex]\displaystyle \frac{4r^2\pi }{9} \text{ cm}^3[/tex]
Step-by-step explanation:
We will write an expression for the second cone's volume. Let r be equal to the radius of the first cone.
The volume of a cone can be found with the following formula. Here, h is the height, r is the radius, and V is the volume.
[tex]\displaystyle V=\frac{1}{3} \pi r^2h[/tex]
We will substitute our given values and simplify.
[tex]\displaystyle V=\frac{1}{3} \pi (\frac{1}{3}*r )^2(12)[/tex]
Square.
[tex]\displaystyle V=\frac{1}{3} \pi \frac{r^2}{9} (12)[/tex]
Divide 12 by 3.
[tex]\displaystyle V=\pi \frac{4r^2}{9}[/tex]
Move π to the numerator.
[tex]\displaystyle V=\frac{4r^2\pi }{9}[/tex]
The volume of the new cone, with the same height but one-third of the original radius, is represented by the expression (4 / 9)πr².
The volume of a cone is given by the formula V = (1/3)πr²h.
For a cone with a radius r and height 12 cm, its volume can be expressed as:
[tex]V = (\frac{1}{3})\pi r^2(12) = 4\pi r^2[/tex]
Now, consider a cone with the same height, but with 1/3 of the original radius. Let the new radius be (1/3)r. Using the volume formula again:
[tex]V = (\frac{1}{3})\pi (\frac{1}{3}r)^2(12) = (\frac{1}{3})\pi(\frac{1}{9}r^2)(12) = (\frac{12}{27})\pi r^2 = \frac{4}{9}\pi r^2.[/tex]
Thus, the expression for the volume of the new cone is (4 / 9) πr².
the half-life of isotope X is 2.0 years. How many years would it take for a 4.0mg sample of X to decay and have only 0.50 mg of it remain
After 2.0 years, the 4.0 mg sample decays to 2.0 mg.
After another 2.0 years (total 4.0 years), the 2.0 mg sample decays to 1.0 mg.
And after another 2.0 years (total 6.0 years), the 1.0 mg sample decays to 0.50 mg.
So it takes 6.0 years for 4.0 mg to decay to 0.50 mg.
It takes for a 4.0 mg sample of X to decay and have only 0.50 mg of it remain is 6 years.

What's the value of x? 40000mg =10x g
The value of x is 4. So 40000 mg= 40 g.
Step-by-step explanation:
The given is 40000mg = 10x g
Step:1
Take given equation as equation (1)
40000 mg= 10x g.................(1)
where, X is known value.
Step:2
Standard value for mg to g for the purpose of conversion of units,
1 milligram = 0.001 gram (or)
1 gram = 1000 milligram
Step:3
From the standard data values,
= 40000 mg
it converted mg to g by dividing 1000
= [tex]\frac{40000}{1000}[/tex] g
= 40 g.......................(2)
Step:4
From the Equations (1) and (2),
40=10x
x=4
Result:
The value of x is 4. So, 40000mg = 40 g.

you have to loan Rs 75000 for 2 years for a purpose. if a finance company A lends money at 10% per annum compounded annually and Finance Company B lends money at 8% per annum compounded semi annually for which Finance Company will you take the loan and why give your reason with calculation
He will take the loan from Company B.
Step-by-step explanation:
Given,
For Company A
Principal (P) = Rs 75000
Time (T) = 2 years
Rate of interest (R) = 10%
For Company B
Principal (P) = Rs 75000
Time (T) = 2 years
Rate of interest (R) = 8%
To find the amount of the loan he has to pay for both the companies.
Formula
Amount =P [tex](1+\frac{R}{100} )^{T}[/tex]
Amount= P[tex](1+\frac{R}{100Xn} )^{nT}[/tex]
For Company A
Amount = 75000[tex](1+\frac{10}{100}) ^{2}[/tex] [ Here, P= 75000, T=2 and R = 10%]
= 194530 (approx)
For Company B
Amount = 75000([tex](1+\frac{8}{200} )^{4}[/tex] [ Here, P= 75000, T=2, n = 2 and R = 8%]
= 87739 (approx)
Hence,
He will take the loan from Company B, because he has to pay less money for this company.
