Which represents a side length of a square that has an area of 450 square inches? 15 sqrt 2 in. 15 sqrt 3in. 112.5 in. 115.5 in.
15√2
area = s² = 450 ← s is length of side
to find s take the square root of both sides
s = [tex]\sqrt{450}[/tex] = [tex]\sqrt{2(9)(25)}[/tex]
= √2 × √9 × √25 = √2 × 3 × 5 = 15√2
15√2 represents a side length of a square that has an area of 450 square inches.
The answer is option A.
How to find the side length of a square?The area of any quadrilateral can be determined by multiplying the length of its base by its height.
area = s² = 450 ← s is length of side
to find s take the square root of both sides
s = √450 = √2(9)(25)
= √2 × √9 × √25 = √2 × 3 × 5 = 15√2
Since we know the shape here is square, we know that all sides are of equal length. From this, we can work backward by taking the square root of the area to find the length of one side.

A bag contains 4 Green Marbles and 5 white marbles suppose a marble is randomly selected what are the odds in favor of picking a white marble
The odds in favor of picking a white marble from a bag with 4 green and 5 white marbles are 5 to 4.
This is calculated by comparing the number of white marbles to the number of green marbles.
Explanation:To determine the odds in favor of picking a white marble from a bag containing 4 green marbles and 5 white marbles, we need to calculate the ratio of the number of successful outcomes (picking a white marble) to the number of unsuccessful outcomes (not picking a white marble).
In this case, the successful outcomes are the 5 white marbles, and the unsuccessful outcomes are the non-white marbles, i.e., the 4 green marbles.
The odds in favor are therefore 5 to 4, or simply, 5:4.
Here's how to calculate odds using a probability example:
The probability of drawing a white marble on the first try isSo, the odds in favor of picking a white marble are 5 to 4.

what is the sine value of 7pi/6
A. - sqrt 3 over 2
B. Sqrt 3 over 2
C. - 1/2
D. 1/2
Answer:
C. -1/2
Step-by-step explanation:
7π/6 radians is equivalent to (7π/6)(180°/π) = 210°, a 3rd-quadrant angle whose reference angle is 30°. The sine of angles in the 3rd quadrant is negative.
sin(30°) = 1/2
sin(210°) = -sin(30°) = -1/2
_____
In radians mode, your calculator can tell you this result directly.
C - [tex]\frac{1}{2}[/tex]
sin(7π / 6 )
note 7π\6 is in the third quadrant where sin is negative
the related acute angle to 7π/6 is 7π/6 - π = π/6
sin (7π/6) = - sin(π/6) = - [tex]\frac{1}{2}[/tex]
The graph below represents the distance of a dog from a trainer after a command is given.
Which statement could describe the dog’s movement 5 seconds after the command was given?
The dog stopped to lie down and obey the trainer’s command.
The dog was running towards the trainer to receive a treat.
The dog was running away from the trainer to chase a squirrel.
The dog was stopped but began running towards the trainer.
Answer:
The dog was running towards the trainer to receive a treat
Step-by-step explanation:
At the point on the graph where Time is 5 (seconds), the slope of the distance vs time curve is negative, indicating the dog is moving toward the trainer. The motivation of the dog is unknown, so the above answer choice involves speculation that is not supported by the problem statement.
Answer:B.The dog was running towards the trainer to receive a treat.

Note that both numbers are multiple of 3: you can simplify the ratio as follows
[tex] \dfrac{6}{603} = \dfrac{3\cdot 2}{3\cdot 201} = \dfrac{2}{201} [/tex]
The ratio can't be further simplified because 2 and 201 are coprime. So, the only thing you could do is write down the decimal expansion of the number.
For the record, its period is 33 digits long, and it is

Step-by-step explanation:
Your car needs fixing and you have two friends that offered to help. Abe can fix it for $70 per hour with a $130 part, but Gabe can fix it for $80 an hour with a $40 part. If Abe could find the part for only $60 instead of $130, how will this affect your decision?
In this case we do not know for how long have they worked. But lets assume that they both will fix the car in an hour.
Case 1: Lets talk about Abe first.
Abe will charge $70.00 per hour plus a part which costs $130.00.
Now, the total cost to be paid to Abe to fix the car is [tex]70+130=200[/tex] dollars.
So we will have to pay $200.00 to Abe to fix the car.
Case 2: Lets talk about Gabe now,
Gabe can fix it for $80 an hour and finds the part just for $60.
Now, the total cost to be paid to Gabe to fix the car is [tex]80+40=120[/tex] dollars.
So we will have to pay $120.00 to Gabe.
Considering the two cases above we can ask Gabe to fix our car but there is another case.
Case 3: What if Abe finds a part for $60.00 rather $130.00
In that case, we will have to pay [tex]70+60=130[/tex] dollars in total to Abe.
Now, we need to pay $130.00 to Abe to fix the car.
Still we can see that we need to pay $10.00 less to Gabe so will ask Gabe to fix the car (since [tex]130-120=10[/tex]).
a. Is it possible for a shape to have both reflectional and rotational symmetry? If so, provide an example with a line of symmetry for reflectional rotation and the minimum degree of rotation for rotational symmetry. If not, explain why.
Yes. For example, the shape I will use is the circle.
No matter how you rotate the circle, it will always look the same. If you reflect the circle over any drawen line in which it passes through the middle, the two halves created would be congruent.

what does 2 3/5 divided by 1 1/25 equal
Alright, so let's make 2 3/5 into an improper fraction.
2 x 5 = 10 + 3 = 13
So 13/5 / 11/25.
Keep, change, flip rule: 13/5 x 25/11.
Now you multiple the numerator and denominator from both fractions. (I'm not going to do the math for you. Hope this helped and sorry if my explanation is...yeah.)
The division of 2 3/5 by 1 1/25 is equal to 2.5.
To perform the division, convert the mixed numbers to improper fractions. 2 3/5 becomes 13/5, and 1 1/25 is 26/25. Now divide the fractions: (13/5) ÷ (26/25) = 13/5 * 25/26 = 325/130 = 2.5.

PLEASE HELP ! Find the number of real solutions for the equation. x^2 - 3x +8 = 0
to determine the nature of the solutions use the discriminant
Given a quadratic equation in standard form : ax² + bx + c = 0
then the discriminant is b² - 4ac
• If b² - 4ac > 0 , then there are 2 real and distinct solutions
• If b² - 4ac = 0, there are 2 real and equal roots
• If b² - 4ac < 0 , there are no real solutions
for x² - 3x + 8 = 0 with a = 1, b= - 3 and c = 8
b² - 4ac = (- 3)² - (4 × 1 × 8 ) = 9 - 32 = - 23

What is the measure of ∠ A in this quadrilateral?
Answer:
30°
Step-by-step explanation:
The sum of the angles of a quadrilateral is 360°. You have 3 angles given, so can find the fourth using that fact. (The double arcs on angles B and C mean those angles are congruent. Same symbols are used to mark same-size angles.)
... 360° = A + B + C + D
... 360° = A + 115° + 115° + 100°
... 360° -330° = A = 30°

mary has 81 coins that have a total value of $5.40. if all of the coins are nickels and dimes how many of each does mary have
54 nickels and 27 dimes
1 dime = 10 cents = $0.1
1 nickel = 5 cents = $0.05
setting up 2 equations
let n = amount of nickels and d = amount of dimes, then
n + d = 81 → (1)
0.05n + 0.1d = 5.4 → (2)
multiply (2 ) by 10
0.5n + d = 54 → (3)
subtract (3) from (1) to eliminate d
0.5n = 27 ( divide both sides by 0.5 )
n = [tex]\frac{27}{0.5}[/tex] = 54
substitute n = 54 in (1)
54 + d = 81 ( subtract 54 from both sides )
d = 27
Mary has 54 nickels and 27 dimes

What is an equation of the line parallel to the line on the graph that passes through (3, 35)?
Answer:
B. y = 2x + 29
Step-by-step explanation:
The given graph has a slope of 2 (a rise of 10 for a run of 5), so the last two chioices are not viable. Clearly a parallel line through the given point will have a positve y-intercept, so the first choice is not viable.
The appropriate choice is the second one:
... B. y = 2x + 29
Hence the line parallel to this is y = 2x + 29.
Hence, option B is correct.
What is line?A straight group of points that stretch in opposing directions is what is known as a line. It is endless in both directions and lacks any ends. It is not thick. It only has one dimension.
In the given graph,
The line is passing through (0, 15) and (10, 35).
Therefore the slope of this lien is,
m = (35-15)/(10-0)
= 2
Now the parallel line to this line will have same slope.
Which passes through (3, 35),
Hence the line be ,
y - 35 = 2(x - 3)
y - 35 = 2x - 6
y = 2x + 29
Hence the line is y = 2x + 29.

Raj tried to solve the system below.
9x-y=15
2x+8y=28
Raj’s Work
9x - y = 15 2x + 8y(15 + 9x) = 28 9(-46/37) - y = 15
-y = 15 - 9x 2x + 120 + 72x = 28 -414/37 - y = 15
y = -15 + 9x 74x + 120 = 28 y = 969/37
74x = -92
x = -46/37
What error did Raj make?
A) Rag forgot to multiply the value of x by 9 when solving for the value of y.
B) When Raj solved for the value of x, he subtracted 120 from both sides.
C) Raj forgot the negative when substituting –15 + 9x for y.
D) Raj found the value of –y instead of y.
Answer: Option C) Raj forgot the negative when substituting -15+9x for y.
Solution:
(1) 9x-y=15
(2) 2x+8y=28
Isolating y in the first equation. Subtracting 9x both sides of the equation:
(1) 9x-y-9x=15-9x
Subtracting:
(1) -y=15-9x
Multiplying both sides of the equation by -1:
(1) (-1)(-y)=(-1)(15-9x)
(1) y=-15+9x
Then Raj found the value of y. It's not option D.
Substitutng y by -15+9x in the second equation:
(2) 2x+8(-15+9x)=28
Then option C) is the answer: Raj forgot the negative when substituting -15+9x for y.
Eliminating the parentheses applying the distributive property in the multiplication:
(2) 2x-120+72x=28
Adding similar terms:
(2) 74x-120=28
Solving for x. Adding 120 both sides of the equation:
(2) 74x-120+120=28+120
Adding:
(2) 74x=148
Dividing both sides of the equation by 74:
(2) 74x/74=148/74
Dividing:
(2) x=2
Solving for y: Replacing x by 2 in the first equation:
(1) y=-15+9x
(1) y=-15+9(2)
Multiplying:
(1) y=-15+18
Subtracting:
(1) y=3
