Troy drew the diagram below. The inner circle has a radius of 2 units, and the outer circle has a radius of 5 units. Troy says the two circles are similar.
Which statement best explains whether Troy is correct, and why?
He is correct because the inner circle is a dilation of the outer circle.
O
He is correct because the inner circle has the same center as the outer circle.
O
He is not correct because the inner circle's radius is less than the outer circle's radius.
He is not correct because the inner circle's radius is not half of the outer circle's radius.
o
Answer:A he is correct because the inner circle is a dilation of the outer circle
Step-by-step explanation: just did the test
The statement "He is correct because the inner circle is a dilation of the outer circle" is the best explanation.
What is dilation?Dilation is the process of modifying the size of an item or form by reducing or expanding its dimensions according to specific scaling variables.
The radius of the inner circle is 2 units, while the radius of the outer circle is 5 units.
Since dilations provide similar figures because multiplying by the scale factor yields proportionate sides while keeping the angle measure and form constant.
Troy is accurate if he claims the two circles are similar.
Hence, the statement (A) "He is correct because the inner circle is a dilation of the outer circle" is the best explanation.

(x+y)² + 2(x+ y)(x- y) + (x– y)²
Answer:
2x(x+y)(x-y)
Step-by-step explanation:
Given the expression;
(x+y)² + 2(x+ y)(x- y) + (x– y)²
Factorize
(x+y)² + (x+ y)(x- y) + (x+ y)(x- y) + (x– y)²
= (x+y)[x+y+(x-y)] +(x-y)[(x+y)+(x-y)]
= (x+y)(x-y)(x+y+(x-y))
= (x+y)(x-y)(x+y+x-y)
= (x+y)(x-y)(2x)
hence the expanded form is 2x(x+y)(x-y)

Answer:
(n + 1) (5m + 4)
Step-by-step explanation:
⇒ (n + 1) (5m + 4)
⇒ 5mn + 4n + 5m + 4
⇒ 5mn + 5m + 4n + 4
Answer:
(n + 1)(5m + 4)
Step-by-step explanation:
Given
5mn + 5m + 4n + 4 ( factor the first/second terms and the third/fourth terms )
= 5m(n + 1) + 4(n + 1) ← factor out (n + 1) from each term

Answer:
y=67.7 Degrees
Step-by-step explanation:
You're given the opposite and adjacent sides to angle Y, so we use Tan to find the angle:
Tan(y)= 100/41
We then inverse tan to isolate y
y=tan^-1 100/41
y=67.7 Degrees

7x10^6 is _________ x the value of 2x10^4
Answer:
350
Step-by-step explanation:
so the first step is to find the values of each of them
7x10^6=7000000
2x10^4=20000
then we divide 7000000 by 20000
7000000/20000=350
so the answer is 350

P varies inversely with x. If P = 7 when x = 8, find the value of P when x = 7. A. 0.125 B. 1 C. 7 D. 8
Step-by-step explanation:
P = 8
Step-by-step explanation:
Given that P varies inversely with x then the equation relating them is
P = \frac{k}{x} ← k is the constant of variation
To find k use the condition P = 7 when x = 8 , then
7 = \frac{k}{8} ( multiply both sides by 8 )
56 = k
P = \frac{56}{x} ← equation of variation
When x = 7 , then
P = \frac{56}{7} = 8

The sum of two numbers is 48.if the smaller number is subtracted from the larger the difference is 12 find the number
Answer:
18
Step-by-step explanation:
30 + 18 = 48
30 - 18 = 12
Both true, so our solution is correct.
The value of the larger number is 30 and the value of the smaller number is 18.
What is a number system?A numeral system is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set in a consistent manner using digits or other symbols. In different numeral systems, the same sequence of symbols can represent different numbers.
Given that the sum of two numbers is 48. if the smaller number is subtracted from the larger the difference is 12. The two numbers will be calculated as,
x + y = 48
x - y = 12
________
2x = 60
x = 30
y = 30 - 12
y = 18
Therefore, the value of the larger number is 30 and the value of the smaller number is 18.

What is the Greatest Common Denominator or factor between 244 & 48
Answer:
GCF = 4.
Step-by-step explanation:
Find the prime factors:
48 = 2*2*2*2*3
244 = 2*2*61
The greatest common factor, the GCF) (picking out the common values) =
2 *2 = 4.
A really clever way of finding the GCF of 2 numbers is Euclid's algorithm. It can be used for very large numbers where it would be time consuming and/or rather difficult to find prime factors:
Given two whole numbers where a is greater than b, do the division a ÷ b = c with remainder R.
Replace a with b, replace b with R and repeat the division.
Repeat step 2 until R=0.
When R=0, the divisor, b, in the last equation is the greatest common factor.
So applying this to our problem:
244 / 48 = 5 remainder 4
Replacing a (244) with 48 and b (48) with R (4):-
48/4 = 12 remainder 0.
So the GCF is 4.
