To find the length of the sides of the isosceles triangle with vertices at A(1, -2), B(-5, 2), and C(2, 6), we need to calculate the distances between the points.

Let's first find the distance between points A and B:

Distance AB = √[(x2 - x1)^2 + (y2 - y1)^2]
Distance AB = √[(-5 - 1)^2 + (2 - (-2))^2]
Distance AB = √[(-6)^2 + (4)^2]
Distance AB = √[36 + 16]
Distance AB = √52 ≈ 7.21 (rounded to 2 decimal places)

Next, let's find the distance between points B and C:

Distance BC = √[(x2 - x1)^2 + (y2 - y1)^2]
Distance BC = √[(2 - (-5))^2 + (6 - 2)^2]
Distance BC = √[(7)^2 + (4)^2]
Distance BC = √[49 + 16]
Distance BC = √65 ≈ 8.06 (rounded to 2 decimal places)

Finally, let's find the distance between points C and A:

Distance CA = √[(x2 - x1)^2 + (y2 - y1)^2]
Distance CA = √[(1 - 2)^2 + (-2 - 6)^2]
Distance CA = √[(-1)^2 + (-8)^2]
Distance CA = √[1 + 64]
Distance CA = √65 ≈ 8.06 (rounded to 2 decimal places)

Since the isosceles triangle has two sides with the same length, the length of these sides is approximately 8.06 units (rounded to 2 decimal places).

To find the coordinates of the point where the line 2x + y = 11 crosses the x-axis, we need to set y to 0 and solve for x.

When y = 0, the equation becomes:

2x + 0 = 11

Now, isolate x:

2x = 11

x = 11 / 2

x = 5.5

So, the point where the line crosses the x-axis has coordinates (5.5, 0).

A square measures 8 inches on each side. What is its area rounded off to the nearest square centimeter? (

Answers

The area of any rectangle is (length) x (width).
Your square is a rectangle, with length=width.

Using  1 inch = 2.54 centimeters, the square's area is

               (8 x 2.54 cm)  x  (8 x 2.54 cm)

           =     (20.32 cm)  x  (20.32 cm)  =  412.90⁺ cm²

Rounded to the nearest cm², it's 413 cm² .

Here is a problem from way back from my bro's math (elementary)3 cats eat 3 cats in 3 minutes
how long does it take for 100 cats to eat 100 fish?

show all work




(hint: answer is not 100 minutes, and if you answer 100 minutes you are wrong and will be reported)

Answers

3 cats -------------- 3  fish -------------3 minutes
100 cats------------100 fish -----------  x

The cats and fish are variables directly proportional, the cats and the time are varibles inversely proportional,
Therefore, 

3 cats * 100 fish * x=100 cats * 3 fish * 3 minutes
x=(100 cats * 3 fish * 3 minutes) / (3 cats * 100 fish)
x=3 minutes.

Answer: the time will be 3 minutes. 

What is the equation of the given line in standard form? Use integer coefficients y = 5/7x - 12 A. -5x + 7y = -12 B. -5x - 7y = -84 C. -5x + 7y = -84 D. 5x + 7y = -84

Answers

y = 5/7 x - 12  / * 7 ( we will multiply both sides of the equation by 7 )
7 y = 5 x - 84
7 y - 5 x = 5 x - 5 x - 84
7 y - 5 x = - 84
- 5 x + 7 y = - 84
Answer:  The equation in standard form is C ) - 5 x + 7 y = - 84 

Saturn’s rings span up to about (7.5 · 10-1) of the distance between the Earth and its moons. If Saturn’s rings span up to (2.82 · 105 kilometers, what is the distance between Earth and its moons. 3.76 · 105 km
21,150 km
21.15 · 104 km
2.115 · 105 km

Answers

The distance between Earth and its moons is 2.115 · 10⁵ km. Then the correct option is D.

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

Saturn’s rings span up to about (7.5 · 10⁻¹) of the distance between the Earth and its moons. If Saturn’s rings span up to (2.82 · 10⁵ kilometers).

The distance between Earth and its moons is calculated as,

⇒ 7.5 · 10⁻¹ x 2.82 · 10⁵

⇒ 0.75 x 2.82 · 10⁵

⇒ 2.115 · 10⁵ km

Thus, the correct option is D.

2.82 × 10^5 = (7.5×10^-1) × Length between the earth and the moon
Length between the earth and the moon = (2.82×10^5)÷(7.5×10^-1)                                                                     = 376000                                                                     = 3.76×10^5
