Five metal cubes with sides of 7 cm are melted and then casted into a spherical ball.
Find the radius of the sphere that is formed. Round your answer to the nearest
hundredth.
To find the radius of the sphere formed by melting five metal cubes with 7 cm sides, calculate the combined volume of the cubes and equate it to the volume of the sphere; then solve for the radius, which is approximately 7.24 cm.
To find the radius of the sphere formed by melting five metal cubes, we need to equate the total volume of the cubes to the volume of the sphere. The volume of a cube with a side length of 7 cm is found by the formula V = s³, where s is the side length of the cube. For one cube, this is V = 7 cm x 7 cm x 7 cm = 343 cm³. Since there are five cubes, the total volume is 5 x 343 cm³ = 1715 cm³.
The volume of a sphere is given by the formula V = 4/3 * π * r³, where r is the radius of the sphere. We must solve for r when the volume is 1715 cm³. Setting the volumes equal gives 4/3 * π * r³ = 1715 cm³. Solving for r yields:
r³ = (1715 cm³) / (4/3 * π)
r = (1715 cm³) / (4.14159)^√(1/3)
r ≈ 7.24 cm
Therefore, the radius of the sphere is approximately 7.24 cm.

First, divide the data set into halves:
70, 70, 72, 75, 79
80, 80, 84, 89, 95
Now, find the median of the two sets. The median of set #1 is 72, as that is the number in the middle of the data.
The median of set #2 is 84 for the same reason.
Upper and lower quartiles are just different words for upper and lower medians. The upper quartile is the higher number, and the lower quartile is the lower number.
Bethany used the steps below in an attempt to solve for angle B in triangle ABC.
4.1 cm
2.7 cm
4.5 cm
[Not drawn to scale]
4.12 - 4.52+2.72 -2(4.5)(2.7)cos B
4.1=4.5+2.7-24.3cos B
-3.1--24 3cOSB
0.1276= COS B
Final answer:
To solve for angle B in triangle ABC, you can use the Law of Cosines. Rearrange the equation to isolate the cosine of angle B and then take the inverse cosine to find the value of angle B. The value of angle B is approximately 99.99 degrees.
Explanation:
To solve for angle B in triangle ABC, you can use the Law of Cosines. The Law of Cosines states that the square of one side of a triangle is equal to the sum of the squares of the other two sides minus twice the product of the other two sides and the cosine of the angle between them.
In this case, you are given the lengths of sides AB, BC, and AC as 4.1 cm, 2.7 cm, and 4.5 cm respectively. You are also given the equation 4.1 = 4.5 + 2.7 - 24.3cos B. To solve for angle B, you can rearrange the equation to isolate the cosine of angle B and then take the inverse cosine to find the value of angle B.
Let's go step-by-step:
Start with the equation 4.1 = 4.5 + 2.7 - 24.3cos B
Subtract 4.5 and 2.7 from both sides: 4.1 - 4.5 - 2.7 = -3.1 - 24.3cos B
Combine like terms: -3.1 - 24.3cos B = -7.1
Add 7.1 to both sides: -3.1 - 24.3cos B + 7.1 = -7.1 + 7.1
Simplify: -3.1 + 7.1 - 24.3cos B = 0
Subtract -3.1 + 7.1 from both sides: -3.1 + 7.1 - 3.1 + 7.1 - 24.3cos B = -3.1 + 7.1
Simplify: -24.3cos B = 4.0
Divide both sides by -24.3 to isolate cos B: (-24.3cos B) / -24.3 = 4.0 / -24.3
Simplify: cos B = -0.1645
Take the inverse cosine of -0.1645 to find the value of angle B: B = cos-1(-0.1645)
Using a calculator, you can find that angle B is approximately 99.99 degrees.

A student said the volume of a cylinder with a 7-inch diameter is two times the volume of a cylinder with
the same height and a 3.5-inch radius. What is the error?
Answer:
When you find the volume of the cylinder you square instead which isn't equal to multiplying so the answer will be more then doubled.
Step-by-step explanation:
Answer:
The volume of the first is not 2 * volume of the second. They both have the same volume.
Step-by-step explanation:
The 2 cylinders described are identical. The diameter = 2 times the radius, so the radius of the first cylinder = 1/2 * 7 = 3.5 in, which is the same as the radius of the second one. Also the heights are the same so the volumes are the same too.

Find the length of the unknown side round your answer to the nearest 10th
Answer:
A. 20
Step-by-step explanation:
[tex]a^{2} + b^{2} = c^{2}[/tex]
Plug in the numbers
[tex]15^{2} + b^{2} = 25^{2}[/tex]
Simplify the equation
225 + b = 625
Subtract both sides by 225
625 - 225 = 400
Your equation should look like
b = 400
Because you squared it, now you have to get it back to the formula you started with first. To do this, just find the square root.
The square root of 400 is 20
[tex]15^{2}+ 20^{2} =25^{2}[/tex]

in the diagram below chords AB and CD intersects at E. If mAC=72 and mAEC=58. how many degrees are in mDB?
Answer:
44°
Step-by-step explanation:
∠ DEB and ∠ AEC are vertical and congruent
Thus ∠ DEB = 58°
The measure of the chord- chord angle DEB is half the sum of the measures of the arcs intersected by the angle and its vertical angle, that is
[tex]\frac{1}{2}[/tex] (DB + AC ) = 58° ( multiply both sides by 2 )
DB + AC = 116°, that is
DB + 72° = 116° ( subtract 72° from both sides )
DB = 44°
Answer:
Hey, and also, The Answer to Your question is 44 Degrees.
Step-by-step explanation:
∠ DEB and ∠ AEC are vertical and congruent
Thus ∠ DEB = 58°
The measure of the chord- chord angle DEB is half the sum of the measures of the arcs intersected by the angle and its vertical angle, that is
(DB + AC ) = 58° ( multiply both sides by 2 )
DB + AC = 116°, that is
DB + 72° = 116° ( subtract 72° from both sides )
DB = 44°...... Stay safe Guys.
Solve the logarithmic equation for x.

x= [
(smaller value)
X
=
(larger value)
Answer:
x = 2 or x = 4
Step-by-step explanation:
Solve: 2 log x = log 2 + log(3x - 4)
log (x^2) = log 2 + log (3x - 4)
log (x^2) = log [2*(3x - 4)]
x^2 = 2*(3x - 4)
x^2 = 6x - 8
x^2 - 6x + 8 = 0
factor:
(x - 2 )(x - 4) = 0
x = 2 or x = 4
Which equation and solution can be used to solve this problem? Twenty-two less than a number is twenty-four. q + 22 = 24: Subtract 22 from both sides. The answer is 2. 24 + q = 22: Subtract 22 from both sides. The answer is 2. q minus 24 = 22: Add 24 to both sides. The answer is 46. q minus 22 = 24: Add 22 to both sides. The answer is 46.
Answer:
D. q minus 22 = 24: Add 22 to both sides. The answer is 46.
Step-by-step explanation:
From the list of options, one would notice that the number is represented with letter q.
So, we'll analyse the question base on the assumption that the number is represented with letter q.
The statement "Twenty-two less than a number is twenty-four".
First, this statement can be splitted into two.
"Twenty-two less than a number" and "is twenty-four."
Taking them one after the other.
"Twenty-two less than a number" as it is means; q - 22
Then we have "is twenty-four."
is represents =
twenty-four = 24
This gives "= 24"
Bringing the two expressions together;
q - 22 = 24
To get the value of q; simply add 22 to both sides
q - 22 + 22 = 24 + 22
q = 46
Hence, option D is correct.

a baseball league finds the speeds of pitches are normally distributed, with a mean of 89 mph and a standard deviation of 2.4 mph. One pitch is thrown at a speed of 85.2 mph. What is the z-score of this pitch? Round your answer to two decimal places.
Answer:
-1.58
Step-by-step explanation:
We have that the mean (m) is equal to 89 and the standard deviation (sd) 2.4
They ask us for P (x <85.2)
For this, the first thing is to calculate z, which is given by the following equation:
z = (x - m) / (sd)
We have all these values, replacing we have:
z = (85.2 - 89) / (2.4)
z = -1.58

Answer:
A company wants to select 3 new employees.
We have 8 candidates, 6 males, and 2 females.
1) What is the number of combinations in which the new employees can be selected?
We have 3 positions.
For the first position, we have 8 options.
For the second position, we have 7 options, because we already selected one.
For the third position, we have 6 options, because we already selected two.
The number of different combinations is (8*7*6)/(3*2*1) = 56
The division by 3*2*1 is because if we no divide by this, we are counting multiple times the same combination of employees, but they are contracted in different orders.
2) How many ways you can select only one male?
In this case, we have 3 positions, two of those positions must be for the 2 women, so in the other position, we can select only one male.
We have 6 different males for that position, so we have only 6 combinations in this case.
3) In how many ways we can select at least one male?
Previously found that we have 56 combinations in total.
We only have 2 women and 3 positions, so in all of these combinations, we have at least one male. So there are 56 combinations with at least one male.
The number of combinations in which these 3 new employees can be selected is equal to 56.
Given the following data:
Number of candidates = 8 candidates.Number of males = 6 males.Number of females = 2 females.Number of employees = 3 new employees.How to find the number of combinations?Since the company needs 3 employees, it simply means there are 3 vacant positions. Thus, the number of combinations in which these 3 new employees can be selected is given by:
_nC_r = \frac{n!}{r!(n-r)!}
Combination(n, k) = n!/(r!(n - r)!)
Combination(8, 3) = 8!/(3!(8 - 3)!)
Combination(8, 3) = 8!/(3!(5)!)
Combination = (8 × 7 × 6)/(3 × 2 × 1)
Combination = 336/6
Combination = 56.
How many ways can a single male be selected?Two (2) of the 3 vacant positions must be taken by 2 women, so we can only select one male. Thus, the number of ways is given by:
Number of ways = 6 × 1
Number of ways = 6.
In how many different ways can at least one male candidate be chosen?Choosing 1 male = 6 ways
Choosing 2 males = two males from 6 males and 1 male from two females.
Comb(6, 2) × 2 = 6!/(2!(6 - 2)!) × 2
Comb(6, 2) × 2 = 6!/(2!(4)!) × 2
Comb(6, 2) × 2 = 15 × 2
Comb(6, 2) × 2 = 30 males.
Choosing 3 males = three males from 6 males;
Comb(6, 3) = 6!/(3!(6 - 3)!)
Comb(6, 3) = 6!/(3!(3)!)
Comb(6, 3) = 20 males.
Total combination = 6 + 30 + 20
Total combination = 56.

Combine the like terms to create an equivalent expression:
- 4y - 4+ (-3)
Answer:
4y - 7
Step-by-step explanation:
Like terms are terms that have the same variable part. Variable part means the part of a term that is one or more variables and the exponents of the variables.
For example, in 2x^2 + 4xy + 5x^2 + 2y + 5 - 3y, the terms 2x^2 and 5x^2 have x^2 as their variable part. They are like terms. Likewise, 2y and -3y have y as their variable part. They are like terms. 2x^2 and 5x^2 can be combined into 7x^2. 2y and -3y can be combined into -y. The terms 4xy and 5 are not like terms and cannot be combined. By combining like terms in 2x^2 + 4xy + 5x^2 + 2y + 5 - 3y, you end up with 7x^2 + 4xy - y + 5.
Now we deal with your problem.
-4y - 4 + (-3)
The term -4y has a y as a variable. There is no other term with a y in it, so the term -4y cannot be combined.
The terms -4 and -3 have no variables. These two terms are like terms and can be combined.
-4y - 4 + (-3) =
-4y - 7

What is the quotient?
Answer:
4 x 10^12
Step-by-step explanation:
4,000,000,000,000
The quotient is 4*10^12.
(6*10^8) / (1.5*10^-4) = 4*10^(8-(-4)) = 4*10^12
6 divided by 1.5 is 4. When the base is the same, and you're dividing, you subtract the exponents. They both have a base of 10, so 8-(-4) gives you 12. So, it would be 10^12.
