Answer:
√689 ≈ 26.2 leagues
Step-by-step explanation:
For the purpose of calculating the distance between the marked points, the line is considered to be the hypotenuse of a right triangle. The horizontal distance between the points is one leg of the triangle, and the vertical distance is the other leg. The Pythagorean theorem relates these distances.
Pythagorean relationThe Pythagorean theorem relates right triangle sides 'a' and 'b' to hypotenuse 'c' with the formula ...
c² = a² +b²
Taking the square root, we have an expression for 'c' in terms of 'a' and 'b'.
c = √(a² +b²)
Application to distanceThe horizontal distance between the points is the difference of their x-coordinates:
a = x2 -x1 = 2 -(-18) = 20
The vertical distance between the points is the difference of their y-coordinates:
b = y2 -y1 = -10 -7 = -17
When we square these numbers, we find their signs to be irrelevant.
c = √(a² +b²) = √(20² +(-17)²) = √(400 +289) = √689
c ≈ 26.249
The distance between the given points is about 26.2 leagues.

Step-by-step explanation:
First, you would want to subtract the 3 on the left side to the right side to get the 1/5x to be alone.
1/5x>6
Next, we need to solve for x, by multiplying 5 to cancel out the 1/5.

How do you find the surface area of this?
Answers
Answer:
132
Step-by-step explanation:
No way you can find the whole area with one solution. So we have to go by each shape.
Let's start with the triangle on top, only one part of it. We know that half of the base is 3. We could go long and hard and use the pythagorean theorem and then repeat that 8 times. Instead, you can imagine moving the 2 triangles into a rectangle. Now you have a rectangle that is 3x4 inches. Repeat 4 times for each of the triangles. Then just the square which is 6x6. Add them and bam!

The circumference of a circle is 125.6 millimeters. What is the circle's diameter?
Use 3.14 for .
Answers
Answer:
C = 2 pi r, so diameter is 40!
Step-by-step explanation
125.6 = 2 pi r
125.6 divided by 2 is 62.8.
Now its, 62.8 = pi times r
62.8/3.14 = 20.
r = 20
but this is the radius so the diameter is 2 times for than the radius. 20 x 2 = 40

-You cant really see what 1 says but it says (The net below can be folded to make the triangular prism? Label the dimensions of the prism.)
And 8 says (Calculate the total area of the net and the surface area of the triangular prism from Problem 7. area net= surface area= ___ cm^2)
Answers
Answer:
1. Left side = 3 inches, Bottom side = 4 inches, Right side = 2 inches, Top side = 5 inches
2. A = 6 inches²
3. A = 8 inches²
4. A = 10 inches²
5. A = 12 inches²
6. A = 36 inches²
7. Left side = 5 cm, Bottom side = 12 cm, Right side = 4 cm, Top side = 13 cm
8. A = 180 cm²
Step-by-step explanation:
1. Label the dimensions of the prism:
Left side = 3 inches
Bottom side = 4 inches
Right side = 2 inches
Top side = 5 inches
2. Area of the red rectangle:
Formula:
LH = A (Length x Height = Area)
A = 3 x 2
A = 6 inches²
3. Area of the blue rectangle:
Formula:
LH = A (Length x Height = Area)
A = 4 x 2
A = 8 inches²
4. Area of the green rectangle:
Formula:
LH = A (Length x Height = Area)
A = 5 x 2
A = 10 inches²
5. (They gave the formula of the two triangles, but the question said green rectangle? They must've meant yellow triangles)
Area of the yellow triangles:
Formula:
2 (1/2 Bh) (2 (half of base x height))
A = 2(1/2 3 x 4)
A = 2(1/2 12)
A = 2(6)
A = 12 inches²
6. Total surface area of the triangular prism:
Formula:
LH + LH + LH + 2 (1/2 Bh) = Surface Area of the triangular prism (Area of the red rectangle + Area of the blue rectangle + Area of the green rectangle + Area of the yellow triangles = Total surface area of the triangular prism)
A = 6 inches² + 8 inches² + 10 inches² + 12 inches²
A = 36 inches²
7. Label the dimensions of the prism:
Left side = 5 cm
Bottom side = 12 cm
Right side = 4 cm
Top side = 13 cm
8. Total surface area of the triangular prism:
First, we can find the area of each shape, as we had previously to find the total area of the net and the surface area of the triangular prism.
Area of the red rectangle:
Formula:
LH = A (Length x Height = Area)
A = 5 x 4
A = 20 cm²
Area of the blue rectangle:
Formula:
LH = A (Length x Height = Area)
A = 12 x 4
A = 48 cm²
Area of the green rectangle:
Formula:
LH = A (Length x Height = Area)
A = 13 x 4
A = 52 cm²
Area of the yellow triangles:
Formula:
2 (1/2 Bh) (2 (half of base x height))
A = 2(1/2 5 x 12)
A = 2(1/2 60)
A = 2(30)
A = 60 cm²
Total surface area of the triangular prism:
LH + LH + LH + 2 (1/2 Bh) = Surface Area of the triangular prism (Area of the red rectangle + Area of the blue rectangle + Area of the green rectangle + Area of the yellow triangles = Total surface area of the triangular prism)
A = 20 cm² + 48 cm² + 52 cm² + 60 cm²
A = 180 cm²

Put the following equation of a line into slope-intercept form, simplifying all fractions. 2x-10y=-20
Answers
Slope-intercept form:
y = mx + b
First, you must get y alone by subtracting 2x on both sides of the equation and then dividing both sides by -10:
-10y = -2x - 20
y = -2/-10x - 20/-10
Simplify: y = 1/5x + 2
Answer: y = 1/5x + 2

What is the volume of this figure?
these are two cuboids side by side, Volume = L * W * h, we find the volume of both and then we add.
4 * 2 * 8 = 64 ft ^ 3
2 * 2 * 3 = 12 ft ^ 3

Find the surface are of this figure
Answers
Answer:
If I am correct, I think the surface area is 448.
Step-by-step explanation:
First start by finding the area of all the sides
Front side. 12 x 10 = 120
2 triangle sides: 8 x 10 = 80, 80 x 2 = 160
Bottom side: 6 x 12 = 72
Back side: 8 x 12 = 96
Then add up the surface area
120 + 160 + 72 + 96 = 448
Btw I don't know if I am correct, but I think this is the way you find surface area.
