Select the perfect square.
23 x 23
924 x 429
18 x 19
Answers
Answer:
23 × 23
Reasoning:
A prefect square is a number times itself
The product of the perfect square can therefore be a sqaure root
23 × 23= 529
Then if we square root 529 it would always be a whole number (23)

b) Measure of Angle E is 112.5, because we know that F and H are vertical angles, so therefore they’re congruent. We also know H and E are adjacent, so H + E = 180.
c) Angles E and K are alternate exterior angles. Measure of Angle K is 112.5.
d) Measure of Angle H is 67.5, because we know that Angle F, which is vertical to Angle H, is 67.5. Vertical angles are congruent.
e) Measure of Angle I is 112.5, because Angle I and Angle K are vertical angles.
f) They’re corresponding angles.

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answers
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143

Answers
Answer:
\(f^{-1}\left(f(576)\right)=\boxed{576}\)
\(f^{-1}(-7)+f(-7)=\boxed{13}\)
Step-by-step explanation:
The inverse of an invertible function with the domain of all real numbers is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).
Given table:
\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&-7&11&-13&6&5&-9\\\cline{1-7}\vphantom{\dfrac12}f(x)&7&12&8&-7&13&5\end{array}\)
Inverse function:
\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&7&12&8&-7&13&5\\\cline{1-7}\vphantom{\dfrac12}f^{-1}(x)&-7&11&-13&6&5&-9\end{array}\)
If we have a function f(x), the inverse function is denoted as f⁻¹(x), and it has the property that f⁻¹(f(x)) = x for all valid inputs x in the domain of f(x).
Therefore:
\(\large\boxed{f^{-1}\left(f(576)\right)=576}\)
The value of f(-7) is the value of f(x) when x = -7. Therefore, reading from the original table, f(-7) = 7.
The value of f⁻¹(-7) is the value of f⁻¹(x) when x = -7. Therefore, reading from the inverse function table, f⁻¹(-7) = 6.
Therefore:
\(\large\boxed{\begin{aligned}f^{-1}(-7)+f(-7)&=6+7\\&=13\end{aligned}}\)

Answers
Answer:

Step-by-step explanation:
1÷1/4 = 1✕4/1 = 1✕4 = 4
The expression is A = 4 and the real life application is solved
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
In an equation, the expressions on either side of the equals sign are called the left-hand side (LHS) and the right-hand side (RHS), respectively. The equals sign (=) indicates that the two expressions have the same value, and that the equation is true for certain values of the variables involved.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. It typically consists mathematical operations, such as addition, subtraction, multiplication, division, and exponentiation.
Given data ,
Let the expression be represented as A
Now , the value of A is
A = 1 / ( 1/4 )
A = 1 x 4 = 4
Now , A real-life application of the expression 1÷1/4 is calculating how long it would take to complete a task if you can complete 1/4 of it in one hour. For example, if you can clean 1/4 of a room in one hour, you can use this expression to calculate how long it would take you to clean the whole room.
1 ÷ 1/4 = 1 x 4/1
On simplifying the equation , we get:
1 ÷ 1/4 = 4
Hence , if you can complete 1/4 of a task in one unit of time, you can complete the entire task in 4 units of time. In the example of cleaning a room, if you can clean 1/4 of the room in one hour, it would take you 4 hours to clean the entire room.

∑ Hey, js1012201 ⊃
Answer:
(A) 4 = 10 - n
(B) 3 = n/2
(D) 8n = 48
Step-by-step explanation:
Given:
Select all the equations where n = 6 is a solution.
Choose 3 answers:
(A) 4 = 10 - n
(B) 3 = n/2
(C) 12 = n + 7
(D) 8n = 48
(E) 5 + n = 8
Solution:
Let's solve each answer choices to see where n = 6 is a solution:
-------------------------------------------------------------------------------------------------------------
(A) 4 = 10 - n
4 + n = 10 - n + n
4 + n = 10
4 + n -4 = 10 - 4
n = 6
(A) n = 6
-------------------------------------------------------------------------------------------------------------
(B) 3 = n/2
Multiply both sides by 2
2n/2 = 3 × 2
n = 6
(B) n = 6
-------------------------------------------------------------------------------------------------------------
(C) 12 = n + 7
Subtract both sides by 7
n + 7 -7 = 12 - 7
n = 5
(C) n = 5
-------------------------------------------------------------------------------------------------------------
(D) 8n = 48
Divide both sides by 8
8n/8 = 48/8
n = 6
(D) n = 6
-------------------------------------------------------------------------------------------------------------
(E) 5 + n = 8
Subtract 5 from both sides
5 - 5 + n = 8 - 5
n = 3
(E) n = 3
