Answer:
P ≈ 25 units
Step-by-step explanation:
LM = 12 units ( horizontal line )
use the distance formula to find length of other 2 sides.
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = L (- 3, 2) and (x₂, y₂ ) = M (3, 5 )
LM = [tex]\sqrt{3-(-3))^2+(5-2)^2}[/tex]
= [tex]\sqrt{(3+3)^2+3^2}[/tex]
= [tex]\sqrt{6^2+9}[/tex]
= [tex]\sqrt{36+9}[/tex]
= [tex]\sqrt{45}[/tex]
Repeat with (x₁, y₁ ) = M (3, 5) and (x₂, y₂ ) = N (9, 2)
MN = [tex]\sqrt{(9-3)^2+(2-5)^2}[/tex]
= [tex]\sqrt{6^2+(-3)^2}[/tex]
= [tex]\sqrt{36+9}[/tex]
= [tex]\sqrt{45}[/tex]
Then perimeter P is the sum of the 3 sides
P = 12 + [tex]\sqrt{45}[/tex] + [tex]\sqrt{45}[/tex] = 12 + 2[tex]\sqrt{45}[/tex] ≈ 25 units ( to the nearest unit )

Answers
Answer:
150 sq. in.
Step-by-step explanation:
Because... Suppose the planned dimensions of a rectangular kitchen have a length-to-width ratio of 3 to 2. The length of the original kitchen is 6z feet. The original kitchen can be made larger by adding four feet to each original dimension. Write a polynomial expression that represents the floor area of the larger kitchen in square feet.
The polynomial expression that represents the floor area of the larger kitchen in square feet is 24z² + 40z + 16
What is Area of Rectangle?The area of Rectangle is length times of width.
The length-to-width ratio of the original rectangular kitchen is 3 to 2.
Let the width of the original kitchen "w".
Then the length of the original kitchen is length = 3/2×w
We are also told that the length of the original kitchen is 6z feet. We can use this information to solve for the width of the original kitchen:
6z = 3/2×w
w = 4z
So the width of the original kitchen is 4z feet.
To make the kitchen larger, we add four feet to each original dimension. The new length is:
length = 6z + 4 feet
width = 4z + 4 feet
Area = (6z + 4 feet) × (4z + 4 feet)
Multiplying out the terms, we get:
Area = 24z² + 40z + 16 square feet
Therefore, the polynomial expression that represents the floor area of the larger kitchen in square feet is 24z² + 40z + 16

Answer:
The 1st choice
Step-by-step explanation:
(a) the first and second ones are the only triangles with all three acute angles. The 2nd one has more than 1 line of symmetry so the 1st must be the answer.
(b) This one really depends on which side of the triangle is each length. One way to do it is A squared + B squared = C squared. 8 equals c because it is the largest side and 7.5 is A. This would be put out like 56.25 + B = 64. Subtract 56.25 from both sides to get B = 7.75.
OR, if 8 is not the longest side 7.5 squared + 8 squared = C squared which would be 120.25 = C squared. So, you would find the square root of 120.25 which is 10.97.

Answer:
x(angle A)=18.9 Angle B=94.5 Angle C=66.6
Step-by-step explanation:
Angle A+ angle B+ Angle C= 180
(x)+(5x)+(4x-9)= 180
add the x components: x+5x+4x= 10x
10x-9 =180
add 9 to each side to balance the equation
10x=189
Divide each side by 10 to get x
10x/10=x 189/10= 18.9
x=18.9
Put x back into the equations
B=5x B=5(18.9) B=94.5
C=4x-9 C=4(18.9)-9
C=66.6
Answer:
We first solve for x, then plug that value into all angle measures.
As selected in the first part,
m∠A + m∠B + m∠C = 180°,
We use this formula to solve for x.
Replace those angle variables with its actual equations, knowing that:
Angle A = x °Angle B = 5x°Angle C = 4x - 9°So, set up the equation:
m∠A + m∠B + m∠C = 180°,
x + (5x) + (4x - 9) = 180°
Solve for x;
x + (5x) + (4x - 9) = 180°
Group and combine like terms;
(5x + x + 4x) + (-9) = 180°
10x - 9 = 180°
Get rid of constants;
+9 +9
10x = 189°
Get rid of co-efficient;
÷10 ÷10
x = 18.9°, x is equal to 18.9°.
Now, plug the value of x into angle 'A':-
x °
(18.9) °
∠A = 18.9°.
Then, plug the value of x into angle 'B':-
5x°
5(18.9) °
94.5°
∠B = 94.5°.
Finally, plug the value of x into angle 'C':-
4x - 9°
4(18.9) - 9°
75.6 - 9°
66.6°
∠C = 66.6°.

Answer:

m6=129
Step-by-step explanation:
m1=51
m2 =39
m3=90
m4=51
m5=17
m6=129
For angle 1 we are given an angle of 39 and the other of 90 so the angle 1 is 51.
Also we are provided angle 1 plus 2 is 90 so the angle 2 is 90-51 which is 39.
Angle 4 can be found by 180-90- 39which is 51.
If 3 is 180- 39-51= 90
Angle 5 can be found by 180-90-34-39 =17
Angle 6 is 180-35-17=129

Answer:
Initially, as x increases, y is constant.
Afterward, the slope of the graph of the function equals 2 for all x between x = 3 and x = 5.
The slope of the graph equals -1 for x between x = 5 and x = 9.
The greatest value of y is y = 4, and it occurs when x = 5.
Step-by-step explanation:
Initially, the graph of the function is flat. The quantity y remains constant as x increases from x = 0 to x = 3. The linear equation that corresponds to the function in that region is y = 0. The slope is m = 0 because the graph is a horizontal line. The graph of the function starts to increase starting at x = 3. The slope, rise/run, once we solve it, is equal to 2 for when x is between 3 and 5. After x = 5, y starts to decrease as x increases. The slope of the graph between x = 5 and x = 9 is -1. The maximum value of y occurs at the top of the bump in the graph. The coordinates of the top of the bump are (5,4). Therefore, the maximum value is y = 4, and it occurs when x = 5.

Eddie purchased 15 boxes of paper clips and 7 packages of index cards for a total of $55.40. Finn bought 12 boxes of paper clips and 10 packages of index cards for $61.70. Find the cost of one box of paper clips and one package of index cards
Answers
The cost of one box of paper clips is $1.85 and the cost of one package of index cards is $3.95
Step-by-step explanation:
Eldora and Finn went to an office supply store together
Eldora bought 15 boxes of paper clips and 7 packages of index cards for a total cost of $55.40
Finn bought 12 boxes of paper clips and 10 packages of index cards for a total cost of $61.70
We need to find the cost of one box of paper clips and the cost of one package of index cards
Assume that the cost of one box of paper clips is $x and the cost of one package of index cards is $y
∵ x represents the cost of one box of paper clips
∵ y represents the cost of one package of index cards
∵ Eldora bought 15 boxes of paper clips and 7 packages of
index cards for a total cost of $55.40
∴ 15x + 7y = 55.4 ⇒ (1)
∵ Finn bought 12 boxes of paper clips and 10 packages of
index cards for a total cost of $61.70
∴ 12x + 10y = 61.7 ⇒ (2)
Now we have system of equations to solve it
Multiply equation (1) by -10 and equation (2) by 7 to eliminate y
∵ -10(15x) + -10(7y) = -10(55.4)
∴ -150x - 70y = -554 ⇒ (3)
∵ 7(12x) + 7(10y) = 7(61.7)
∴ 84x + 70y = 431.9 ⇒ (4)
Add equations (3) and (4)
∵ (-150x + 84x) + (-70y + 70y) = (-554 + 431.9)
∴ -66x = -122.1
- Divide both sides by -66
∴ x = 1.85
Substitute the value of x in equation (1) or (2) to find y
∵ 12(1.85) + 10y = 61.7
∴ 22.2 + 10y = 61.7
- Subtract 22.2 from both sides
∴ 10y = 39.5
- Divide both sides by 10
∴ y = 3.95
The cost of one box of paper clips is $1.85 and the cost of one package of index cards is $3.95

A store is giving out cards labeled 1 through 10 when customers enter the store. If the card is an even number, you get a 15% discount on your purchase that day. If the card is an odd number greater than 6, you get a 30% discount. Otherwise, you get a 20% discount. The table shows the results of 400 customers. What is the relative frequency for each discount? If the manager of the store wants approximately half of the customers to receive the 20% discount, does this seem like an appropriate method? Explain.
Answers
Answer:
No
Step-by-step explanation:
It is not an appropriate method because if you add all of the people that got 1, 3, and 5 together to get all the people that got the 20% discount, you get 140/400 people, and in order for it to be half there would have to be, or close enough to, a total of 200/400 people.
15% discount = 185/400 or 46.25%
20% discount = 140/400 or 35%
30% discount = 75/400 or 18.75%

Step-by-step explanation:
Since the mural is 10 feet on one side we can make the size of Ociel's mural just 10². Of course, the same would go for Bill's mural except we square however long one of his sides is. So just subtract Bill's (y²) from Ociel's (10²).
