Answer:
The north - south distance across swan lake is 8 km
Step-by-step explanation:
Look to the attached figure
Kendra's house and the distances between it and the North tip, southern tip of swan lake formed a right Δ
∵ Kendra lives 10 Km from the northern tip of swan lake
- That means the length of the hypotenuse of the right Δ is 10
∴ The hypotenuse of the right Δ = 10
∵ Kendra lives 6 Km from the southern tip of swan lake
- That means the length of the horizontal leg of the right Δ is 6
∴ The horizontal leg = 6
- By using Pythagoras Theorem
∵ (hypotenuse)² = (H.leg)² + (V.leg)²
∴ (10)² = (6)² + (x)²
∴ 100 = 36 + x²
- Subtract 36 from both sides
∴ 64 = x²
- Take √ for both sides
∴ 8 = x
∴ The vertical leg of the right triangle = 8
∵ x represents the north-south distance across swan lake
∴ The north - south distance across swan lake is 8 km
Square OSER, ER equals (2a+b) what is the area of square OSER
Answer:
4a² + 4ab + b² units²
Step-by-step explanation:
Area of a square = Length²
ER is a length of the square
ER = (2a + b)
Area of a square = (2a + b)² = (2a + b)(2a + b) = (2a)(2a) + (2a)(b) + (2a)(b) + (b)(b) = 4a² + 4ab + b²
The area of the square OSER = [tex]4a^{2}+4ab+b^{2}[/tex] sq unit
Step-by-step explanation:
Given,
Length of each side(ER) = (2a+b) unit
To find the area of the square OSER.
Formula
The area of a square with each side a unit is [tex]a^{2}[/tex] sq unit
[tex](a+b)^{2}= a^{2} +b^{2} +2ab[/tex]
Now,
The area of the square OSER = [tex](2a+b)^{2}[/tex] sq unit
= [tex]4a^{2}+4ab+b^{2}[/tex] sq unit [ by using the formula of ([tex]a+b)^{2}[/tex]]

= 4 /8
= 1 /2 or 0.5
Answer:
1/2
Step-by-step explanation:
To multiply fractions we do keep change flip, keeping the first fraction, changeing the division into multiplication and flipping the last fraction so we don't have to go into decimals so 1/8 divded by 1/4 becomes
1/8 * 4/1
Now we multiply the numerators together and the denominators together and then put it back in fraction form. Another option is to cross reduce, both will be shown.
Multiplying numerators and denominators
1 * 4 = 4
8 * 1 = 8
Put it into fraction form;
4/8 Now simplify
1/2
Cross Reducing
To cross reduce you can divde two numbers that are accross from each other in a fraction equation (Multiplication only) by the same number
1/8 * 4/1 The four and eight are across from each other so we can cross reduce by 4 because that is there gcf
then we have
1/2 * 1/1 now we multiply the numerators by numerators and the denominators by denominators in this case we don't have to go that far though because 1/1 is 1 and anything times one is itself, therefore the awnser is
1/2

The coordinates of the vertices of quadrilateral ABCD are (7, -7), (4, -10), (1.5, -2.5), and (6, -3), respectively.
If quadrilateral ABCD is rotated 180° counterclockwise about the origin, what are the coordinates of D’?
A. (6, 3)
B. (3, -6)
C. (-6, 3)
D. (-3, 6)
C. Coordinates of D' (-6,3)
Step-by-step explanation:
When any figure is rotated 180° in the counterclockwise direction, then the coordinates of the vertices is changed into its opposite sign.
(x, y) → (-x, -y)
The coordinates of the vertices of quadrilateral ABCD is changed when it is rotated 180 degrees counterclockwise about the origin as,
A (7,-7) → A'(-7,7)
B (4,-10) → B' (-4,10)
C (1.5, -2.5) → C' (-1.5, 2.5)
D (6, -3) → D'(-6,3)
So the coordinates of D' will be (-6,3)

Step-by-step explanation:
that the ansewer if you divid
Final answer:
The length of the rectangle with a perimeter of 60 inches and a width of 12 inches is 18 inches, calculated using the perimeter formula for rectangles and solving for the length.
Explanation:
The question asks us to find the length of a rectangle given its perimeter and width. To solve this, we use the formula for the perimeter of a rectangle, which is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width. In this case, we have P = 60 inches and w = 12 inches.
So, substituting the given values into the formula, we get:
60 = 2l + 2(12)
First, calculate the double of the width:
2(12) = 24 inches
Now, subtract this value from the total perimeter to find the double of the length:
60 - 24 = 36 inches
Finally, divide by 2 to find the length of the rectangle:
36 / 2 = 18 inches
Therefore, option B, 18 inches, is the correct answer for the length of the rectangle.

Solving the elimination method what is 3x-y=9 2x-y=7
Answer:
x = 2 , y = -3
Step-by-step explanation by elimination:
Solve the following system:
{3 x - y = 9 | (equation 1)
2 x - y = 7 | (equation 2)
Subtract 2/3 × (equation 1) from equation 2:
{3 x - y = 9 | (equation 1)
0 x - y/3 = 1 | (equation 2)
Multiply equation 2 by 3:
{3 x - y = 9 | (equation 1)
0 x - y = 3 | (equation 2)
Multiply equation 2 by -1:
{3 x - y = 9 | (equation 1)
0 x+y = -3 | (equation 2)
Add equation 2 to equation 1:
{3 x+0 y = 6 | (equation 1)
0 x+y = -3 | (equation 2)
Divide equation 1 by 3:
{x+0 y = 2 | (equation 1)
0 x+y = -3 | (equation 2)
Collect results:
Answer: {x = 2 , y = -3

(100 POINTS) Can anyone solve this math equation for me? Thank you!
Answer:
Step-by-step explanation:
Given that,
x^8/x^a=x²
Applying indices
Division rule a^m ÷ a^n = a^(m-n)
Then,
x^8/x^a=x²
x^(8-a)=x²
For this to be equal means that, the power are equals since they have the same base
Then, 8-a=2
8+2=a
So, a=10
Taking the second equation
(x^6)^b=x¹²
Using indices again
x^(6b)=x¹²
Also, for this to be equal
6b=12
Then, b=12/6
b=2
Then, b=2 and =10
We need to find b-a.
b-a=2-10=-8
Then, the answer to b-a is -8
Micahdisu please help
Answer:
1) A - 42°
2) 74°
3) B - 45°
4) B - 66°
Step-by-step explanation:
1) E = D+H
87 = 45 + H
H = 42°
2) 180 - 50 - D
D = 180 - 44 - 62 = 74°
3) F = 105
H = 180-105 = 75
I + H = C + E
I + 75 = 83 + 37
I = 45°
4) D = 180 - (E + F)
D = 180 - (30 + 57) = 93°
93 = A + 27
A = 66°
Answer: In figure 1, angle H = 42°. In figure 2, angle F = 56°. In figure 3, angle I = 45° and in figure 4, angle A = 66°
Step-by-step explanation: Please refer to the attached diagram for details.
From figure 1, if angle E measures 87, then angle F would be calculated as
Angle F = 180 - 87 {Sum of angles on a straight line equals 180}
Angle F = 93
Then looking at triangle FHD, we have angles D and F as 45 and 93. Angle H = 180 - (45 + 93) {Sum of angles in a triangle equals 180}
Angle H = 180 - 138
Angle H = 42
From figure 2, if triangle ACB has two angles given as 44 and 62, then the third angle C, would be calculated as
Angle C = 180 - (44 + 62) {Sum of angles in a triangle equals 180}
Angle C = 180 - 106
Angle C = 74
Note that angle D equals angle C {Opposite angles are equal}. So if angle D measures 74, then looking at triangle FED, we have two angles already, E and D which are 50 and 74. To calculate angle F, the equation would be
f = 180 - 50 - 74
f = 56
That is, angle F = 56.
From figure 3, we have angles C and E given as 83 and 37. To calculate angle G
Angle G = 180 - (83 + 37) {Sum of angles on a straight line equals 180}
Angle G = 180 - 120
Angle G = 60
Also, to calculate angle H,
Angle H = 180 - 105 {Sum of angles on a straight line equals 180}
Angle H = 75
Looking at triangle GHI, we have identified two angles which are 60 and 75. To calculate the third angle which is angle I,
Angle I = 180 - (60 + 75) {Sum of angles in a triangle equals 180}
Angle I = 180 - 135
Angle I = 45
From figure 4, if angles B and E measure 27 and 30 respectively then the whole of that angle measures 27 + 30 which equals 57.
So looking at the biggest of all three triangles, two angles have been identified which are angles F and {B + E}
To calculate angle A
Angle A = 180 - (57 + 57) {Sum of angles in a triangle equals 180}
Angle A = 180 - 114
Angle A = 66.
