Mai has a jar of quarters and dimes. She takes at least 10 coins out of the jar and has less than $2.00.
Write a system of inequalities that represents the number of quarters, , and the number of dimes, , that Mai could have.
Is it possible that Mai has each of the following combinations of coins? If so, explain or show how you know. If not, state which constraint—the amount of money or the number of coins—it does not meet.
3 quarters and 12 dimes
4 quarters and 10 dimes
2 quarters and 5 dimes

Problem 8
A stadium can seat 63,026 people. For each game, the amount of money that the organization brings in through ticket sales is a function of the number of people, , in attendance.
If each ticket costs $30.00, find the domain and range of this function.
Answer:
The system of inequalities that can represent the situation is25q+0.1d<2.00 and x+y≥10.
Yes, it is possible because 3 + 12≥10 and 3 quarters and 12 dimes total $1.95 which is less than $2.00.
This is not possible because 4 quarters and 10 dimes is exactly $2.00, which is not less than $2.00.
This is not possible because 2 quarters and 5 dimes is only 7 coins, which is not at least 10 coins.

If 30% of people that enter a comic store buy something on an average day how many people entered that comic store if 45 people made a purchase?
Answer:
150 people entered the comic store.
Step-by-step explanation:
First, divide 45 by 3 to turn the %30 into %10, a better number to get to a %100 easier. You get 15. Then multiply 15 by 10 to get to %100, which is 150.

20/3 = ?/6 what is the answer to the question mark
Answer:
40. 3*2 is equal to 6 so 20*2 equals 40
The value of the missing number in the equation is 40.
What is the value of the missing number?Given the equation in the question:
20/3 = ?/6
Let x represent the missing number:
Hence:
20/3 = x/6
To solve for x, we cross-multiply and simplify:
20/3 = x/6
Cross multiplying, we get:
3 × x = 20 × 6
Multiply 3 and x:
3x = 20 × 6
Multiply 20 and 6:
3x = 120
Divide both sides by 3:
x = 120/3
x = 40
Therefore, the value of x is 40.

Answer:
use the definition of isosceles to claim congruent sides (or angles), and use the shared side and the fact that angles at C are 90°. Claim HL or AAS congruence.
Step-by-step explanation:
Approach to the problem
Of course, AC is congruent to itself. AC ⊥ BD means ∠ACB ≅ ∠ACD ≅ 90°. Then the fact that the larger triangle is isosceles lets you claim angle B = angle D, or AB = AD (or both).
If you use the congruence of angles, you can claim AAS congruence for the triangles. If you use the congruence of sides, you can claim HL congruence for the right triangles.
Specifics
1. ∠ACB ≅ ∠ACD (= 90°) . . . . definition of perpendicular
2. AB ≅ AD . . . . definition of isosceles triangle
3. AC ≅ AC . . . . reflexive property of congruence
4. ∆BAC ≅ ∆DAC . . . . HL congruence theorem
Suppose that Prolog facts are used to define the pred- icates mother(M, Y) and father(F, X), which represent that M is the mother of Y and F is the father of X, re- spectively. Give a Prolog rule to define the predicate grandfather(X, Y), which represents that X is the grand- father of Y. [Hint: You can write a disjunction in Prolog either by using a semicolon to separate predicates or by putting these predicates on separate lines.]
Answer and Explanation:
The Prolog rule expresses that logical implication (:-) describes the relationship between facts.
Prolog expressions are containing truth-functional symbols, which have the same intervention as in predicate calculus.
For example:
English Predicate calculus prolog
and ^ ,
or v ;
By using information, given in the question,
We can make prolog:
Grandfather(X, Y) :-mother(M,Y), father(X,M); father (F, Y), father(X,F)
Prolog (:- ) means define,
Prolog (,) represents a conjunction
And
Prolog (;) represent a disjunction

What is the slope of the line defined by the equation --3x + 1 = y?
A: -3
B: -1
C: 1
D: 3
Write an equation for a line parallel to y =4x + 3 and passing through the point (3,-11).
HELP
Answer:
y = -4x + 1
Step-by-step explanation:
y = -4x + 3
Passing through point (3, -11)
y = mx + b
-11 = -4(3) + b
-11 = -12 + b
b = 1
Use b from above to make new equation of line going through given point (3, -11)
y = -4x + 1
Original: y = -4x + 3
One that pass through given point: y = -4x + 1
The slope is -4 in both equations so they are parallel.

Arman is building a bench. The bench comes out from the wall and there is a brace supporting the bench as shown in the figure below. The angle created between the wall and the brace is 52.6°. Which equation can be used to solve for the missing angle?
Answer:
x+ 52.6°.+90=180--------1
Step-by-step explanation:
Hey!!!, we can imagine the right angles triangle formed. ok, let imagine it this way.
1. the bench comes out perpendicular to the wall
2. The brace forms an angel of 52.6
3. then the angle formed between the bench and the wall is 90°.
we know that the sum of angles in a triangles is 180°
let the third angle be x
Therefore the equation to find the missing angle is
x+ 52.6°.+90=180---------------1
x+142.6=180
x=180-142.6
x=37.4°

Answer:
x = -8
Step-by-step explanation:
Step 1: Write equation
1/2x + 13 = 9
Step 2: Solve for x
Subtract 13 on both sides: 1/2x = -4Multiply both sides by 2: x = -8Step 3: Check
Plug in x to verify it's a solution.
1/2(-8) + 13 = 9
-4 + 13 = 9
9 = 9
Answer:
-8
Step-by-step explanation:
you use inverse operation
meaning opposite signs
subtract -13 from 13 cross it out
subtract 13 from 9
you get 1/2x=-4
divide 1/2 on both sides
-4 divided by 1/2 =-8
True or False: f(2)= - 8 for the function f(x)= 3x - 14
Answer:

Step-by-step explanation:
Step 1: Write equation
f(x) = 3x - 14
f(2) is x = 2
Step 2: Substitute and Evaluate
f(2) = 3(2) - 14
f(2) = 6 - 14
f(2) = -8

What is the value of 4n-2n=4
Answer:
n=2
Step-by-step explanation:
subtract 4n - 2n
2n=4
divide by 2 to get rid of the two on the n side
n=2
The value of n in the equation 4n - 2n = 4 is n = 2.
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
To find the value of n in the equation 4n - 2n = 4, combine like terms on the left side of the equation:
4n - 2n = 4
(4 - 2)n = 4
2n = 4
To isolate n, we divide both sides of the equation by 2:
2n/2 = 4/2
n = 2
Therefore, the value of n in the equation 4n - 2n = 4 is n = 2.
