Draw a point B, then draw any two other points D and E. The rays BD and BE are essentially arrows that both start at B and pass through D and E, respectively. See the attached sketch. Note that the points D and E need not lie on a circle like the dotted one in the sketch; they can be placed anywhere along the ray.
Then:
• (I) is sometimes true. Rays can be parallel as long as they are collinear, meaning the three points B, D, and E would need to lie on the same line. (The first sketch shows one example)
• (II) is always true.
• (III) is sometimes true, if the angle the two rays form is a right angle. (The second sketch shows one example)
• (IV) is never true, because B would have to lie on the circle itself. The center does not.
Without knowing what Damiana's/Valeria's drawing looks like, the most we can do is rule out C and D.

From a cylinder of height of 24cm and base diameter 14cm, a cone having equal radius and height is hollowed out. Find the volume of the remaining solid of the cylinder.
Answers
Answer:
2463 cm^3
Step-by-step explanation:
Given that a cylinder of height of 24cm and base diameter 14cm, a cone having equal radius and height is hollowed out. Find the volume of the remaining solid of the cylinder.
Let first calculate the volume of the cylinder
V = πr^2h
Where the radius = 7 cm
V = π × 7^2 × 24
V = 3694.5 cm^3
Let's calculate the volume of a cone
V = 1/3πr^2h
V = 1/3 × π × 7^2 × 24
V = 1/3 × 3694.5
V = 1231.5 cm^3
To Find the volume of the remaining solid of the cylinder, minus the volume of a cone from the volume of a cylinder
Remaining volume V = 3694.5 - 1231.5
V = 2462.99 cm^3
V = 2463 cm^3 approximately

Rachel and David were shopping for holiday gifts when they noticed a Thanksgiving sweater on the discount rack. Rachel really wanted the sweater, even though she wouldn’t be wearing it until Thanksgiving of 2021! Part A: If the original price of the sweater was $24.00, and the sweater is on sale for 60% off, what is the sale price?
Answers
Answer:
[tex]Sales\ Price = \$9.60[/tex]
Step-by-step explanation:
Given
[tex]Price = \$24.00[/tex]
[tex]Discount = 60\%[/tex]
Required
Determine the sales price
First, we calculate the discount price
[tex]Discount\ Price = Price * Discount[/tex]
[tex]Discount\ Price = \$24.00 * 60\%[/tex]
[tex]Discount\ Price = \$14.4[/tex]
The sales price is then calculated by subtracting the discount price from the original price of the item
[tex]Sales\ Price = Price - Discount\ Price[/tex]
[tex]Sales\ Price = \$24.00 - \$14.40[/tex]
[tex]Sales\ Price = \$9.60[/tex]

Answers
Answer:
x=5 and y=-6
Step-by-step explanation:
2(5) + 5(-6) = -20 (so true)
and
2(5) - 3(-6) = 28 (true)
Answer:
2x=-20-5y
divide both sides by 2
x=-20-5y/2
2x-3y=28
-3y=28-2x
divide both sides by -3
y=28-2x/-3

Estimate the number of words in your textbook, without using a calculator.(The book has about 500 pages, with an average of 38 lines on a page, 12 words on a line.)
Answers
Answer:
[tex]500\ Pages = 228000[/tex]
Step-by-step explanation:
Given
[tex]Pages = 500[/tex]
[tex]Lines = 38[/tex]
[tex]Words = 12[/tex]
Required
Determine the number of words in the book
First, we need to calculate the number of words in a page.
[tex]1\ Page = Words * Lines[/tex]
[tex]!\ Page = 12 * 38[/tex]
[tex]1\ Page = 456[/tex]
Next, we calculate number of words in 500 pages
Multiply both sides by 500
[tex]500 * 1\ Page = 456 * 500[/tex]
[tex]500\ Pages = 228000[/tex]
Hence, there are 228000 words in the book

Answers
Answer:
(4a + b)/(2ab + b)Step-by-step explanation:
Givena = log9 2b = log5 4To findlog6 15 in terms of a and bSolutionRewrite the given
log9 2 = a ⇒ log2/log9 = a ⇒ 1/2*log2/log3 = a ⇒ log3 = 1/2*log2/alog5 4 = b ⇒ log4/log5 = b ⇒ log5 = 2*log2/bRewriting the log6 15:
log6 15 = log15/log6= (log 5 + log3)/(log2 + log3)Substitute as follows:
(log 5 + log3)/(log2 + log3) =(2*log2/b + 1/2*log2/a)/(log2 + 1/2*log2/a) =(2/b + 1/(2a))/(1 + 1/(2a)) =(4a + b)/2ab ÷ (2a + 1)/2a =(4a + b)/(2ab + b)Which is a simplified form of the following expression?
