Answer:
B = Base area of a cone
Step-by-step explanation:
Renzo used the formula V = 1/3 B h to determine the volume of a cone. What is the meaning of B in the formula?
The formula for the volume of a cone = 1/3 πr²h
A cone has a base area = B and the formula = πr²
Substituting this into the formula for a cone
The volume of a cone = 1/3 BH
Hence, B = Base area of a cone

Answer:
A. 4x * 2x^2 + 4x * (-2) + 1 * 2x^2 + 1 * (-2)
Step-by-step explanation:
We have the binomial (4x + 1)(2x^2 - 2) and are asked to see how it looks like expanded.
When solving binomials, we need to follow the FOIL method :
First - First number in first parenthesis multiplied by first number in second parenthesis
Outer - First number in first parenthesis multiplied by second number in second parenthesis
Inner - Second number in first parenthesis multiplied by first number in second parenthesis
Last - Second number in first parenthesis multiplied by second number in second parenthesis
If we follow the definitions given, we can find our correct answer and also see where all the other answers mess up at :
A. 4x*2x^2+4x*(-2)+1*2x^2+1*(-2)
This follows FOIL entirely from start to finish.
B. 4x*2x^2+4x*(-2)+1*4x+1*(-2)
This did not follow the Inner part of FOIL.
C. 4x*2x^2+4x*(1)+1*2x^2+1*(-2)
This did not follow the Outer part of FOIL.

The whole numbers between 20 and 50 are 20, 24, 28, 32, 36, 40, 44, 45, 48.
What are whole numbers?A whole number is defined merely as any positive number that does not consider a fractional part or any decimal part of the numbers.
For example, the numbers 0, 1, 2, 3, 4, 5, 6, and 7 are all whole numbers. Numbers such as -9, 6.2, or 2 ½ are not whole numbers.
Therefore, the whole numbers that are on the gap between of 4 between 20 and 50 are the 20, 24, 28, 32, 36, 40, 44, 45, 48.

Jacqueline is deciding between two mortgages for her new home. The first
mortgage is an 80/20 mortgage with interest rates of 4.75 and 7.525%,
respectively. The second mortgage is a 30-year mortgage with a 5.25% and a
$58.30 monthly PMI. If the house price is $145,000, which mortgage payment
will be lower initially, and by how much?
A. 30-year mortgage by $49.93
B. 80/20 mortgage by $41.34
C. 80/20 mortgage by $50.62
D. 30-year mortgage by $33.56
Answer:
80/20 mortgage by $37.25
Step-by-step explanation:
First mortgage
0.8 × 145000 = 116000 PMT multiply both of them
= 116000(.0475/12) / [1 - (1 + .0475/12)^(-12 * 30)] PMT = 605.11
The 2nd Mortgage 0.2 × 145000 = 29000
2nd mortgages are normally only interest payments
I = 29000(.07525/12) I = $181.85 divide the interests by the denominator
605.11 + 181.85 = 786.96
Second Mortgage
PMT = 145000(.0525/12) / [1 - (1 + .0525/12)^(-12 * 30)] divide the mortage
PMT = 800.70
800.7 + 58.3 = 859.00
Therefore, the 80/20 mortgage is lower by $37.25¢

Billy and Tommy are playing a dice game with a six-sided die. Billy needs to roll a 5 or higher to win the game. What is the probability that Billy will roll a 5 or higher?
Answer:
Probability that Billy will roll a 5 or higher [tex]=\frac{1}{3}[/tex]
Step-by-step explanation:
Probability refers to chances of occurrence of any event.
If a six-sided die is thrown, possible outcomes are [tex]1,2,3,4,5,6[/tex].
Billy needs to roll a 5 or higher to win the game.
So,
Favorable outcomes are [tex]5,6[/tex]
Number of favorable outcomes [tex]=2[/tex]
Total number of outcomes [tex]=6[/tex]
Probability that Billy will roll a 5 or higher
= Number of favorable outcomes ÷ Total number of outcomes
[tex]=\frac{2}{6}[/tex]
[tex]=\frac{1}{3}[/tex]

A fashion blog has 22,000 page views so far. In addition, that number grows 25% every week. Which function can be used to determine the number of page views the blog will have after x weeks?
Answer: 22,000 * 1.25^ x
Step-by-step explanation:
The number of pages grows at 25% every week. This number is based on the previous week's number of pages so the increase in page number is being compounded.
Use the future value equation to determine the number of pages after x weeks.
FV = Amount * ( 1 + rate of increase) ^ time
= 22,000 * ( 1 + 25%) ^ x
= 22,000 * 1.25^x

Consider these three squares with known area. 3 squares. The smallest square is labeled 25, the next square is 144, and the largest square is 169. Can a right triangle be formed using these squares?
Answer:
The answer is "5, 12, and 13".
Step-by-step explanation:
Please find the complete question in the attached file.
The right triangle is a triangle with only an angle of 90 degrees, as well as the go in the angle of 90 degrees, which is considered a hypotenuse.
The hypotenuse calculation square is equivalent to both the squared measures of the other two sides:
[tex]C^2=A^2+B^2[/tex]
And even those squares do verify the equation:
[tex]169 = 144 + 25[/tex]
So, it's a rectangular (right) triangle, with sides spanning [tex]5, 12, \ and \ 13.[/tex]

Step-by-step explanation:
the manager of a bookstore uses the equation s = p - 3.5 to find the price a student pays for books
The sale price 's' of a book is $3.50 less than the original price 'p'. This situation is represented by the given equation s = p - 3.5.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is s = p - 3.5, where 's' represents the sale price and 'p' represents the original price of a book.
The equation shows that to get the sale price 's', the original price 'p' is reduced by $3.50.
If the sale price 'p' of a book is $3.50 less than the original price 's', then we can rewrite the equation as p = s + 3.5.
This situation is not represented by the given equation.
If the sale price 's' of a book is $3.50 more than the original price 'p', then the equation would be s = p + 3.5.
This situation is also not represented by the given equation.
Hence, the sale price 's' of a book is $3.50 less than the original price 'p'. This situation is represented by the given equation s = p - 3.5.

In right △ABC altitude overlineBD is drawn to hypotenuse overline{AC} If AD = 5 and BC = 2√ 21, find DC, BD, and ABAB.
Answer:
[tex]\overline {DC}[/tex] = 7
[tex]\overline {BD}[/tex] = √35
[tex]\overline {AB}[/tex] = 2·√15
Step-by-step explanation:
Please find attached the drawing of right triangle ABC created with MS Visio
Let 'x' represent [tex]\overline {BD}[/tex] let 'y' represent [tex]\overline {DC}[/tex], and let 'z' represent [tex]\overline {AB}[/tex], we get;
5² + x² = z²...(1)
x² + y² = (2·√21)² = 84
x² + y² = 84...(2)
84 + z² = (5 + y)²...(3)
From equation (1), we have;
x² = z² - 5²...(4)
From equation (2), and equation (4), we have;
x² + y² = 84 = (z² - 5²) + y² = 84
∴ z² = 84 - y² + 5² = 109 - y²
z² = 109 - y²...(5)
From equation (3), and equation (5), we have;
84 + z² = (5 + y)² = 84 + (109 - y²) = (5 + y)²
84 + (109 - y²) = (5 + y)²
(5 + y)² - (84 + (109 - y²)) = 0
2·y² + 10·y - 168 = 0
y² + 5·y - 84 = 0
y = (-5 ± √(5² - 4 × 1 × (-84)))/(2 × 1)
y = 7, or y = -12
We note that 'y' is a natural number, therefore, the correct option of the two options is y = 7
y = [tex]\overline {DC}[/tex] = 7
From equation (2), we have;
x² + y² = 84
x² = 84 - y² = 84 - 7² = 35
x = √35
x = [tex]\overline {BD}[/tex] = √35
z² = 109 - y²
∴ z² = 109 - 7² = 60
z = √60 = 2·√15
z = 2·√15
z = [tex]\overline {AB}[/tex] = 2·√15.
