Does a linear equation have no solution, one solution, or infinitely many solutions?

I think that a linear equation can have no solution, one solution, or infinitely solutions. It just depends on what is the equation. That's what I think

What’s the height of the can?

kondaur [170]

Answer:

5 inches

Step-by-step explanation:

The formula to find the surface area of a cylinder is A = 2πrh + 2πr²

Since we need the height we will need to solve for h

First we can subtract 2πr² from both sides to get A - 2πr² = 2πrh
Then we can divide both sides by 2πr to get $h=\frac{A-2\pi r^{2} }{2\pi r}$

Now we can plug in our known values and solve for h

Here we were given the diameter, d, however this formula is in terms of the radius, r.
The diameter is equivalent to double the radius, d = 2r
Therefore the radius is equivalent to half the diameter, $r=\frac{1}{2} d$
Plugging in d to solve for r we get $r=\frac{1}{2}(2)$ which simplifies to r = 1

The two variables for this equation we have no obtained, A = 12π and r = 1, so we can plug them into our equation to solve for the height

$h=\frac{12\pi -2\pi (1)^{2} }{2\pi (1)}=h=\frac{12\pi -2\pi }{2\pi }=\frac{10\pi }{2\pi } =5$
The height is 5 inches

Please help answer and explanation im very confused.

Veseljchak [2.6K]

Answer:

1) 18m²

2) 25cm²

Step-by-step explanation:

a = ½ × b × h
a = ½ × 9 × 4
a = ½ × 36
a = 18m²

a = ½ × b × h
a = ½ × 10 × 5
a = 5 × 5
a = 25 cm²

If w = 10 units, x= 5 units, and y= 6 units, what is the surface area of the figure?

qwelly [4]

Answer:

456.2 units²

Step-by-step explanation:

The area of the square base is ...

base area = w² = (10 units)² = 100 units²

The lateral area is 4 times the area of one rectangular face:

lateral area = 4wx = 4(10 units)(5 units) = 200 units²

The area of one triangular face is half the product of its base length (w) and its slant height (h). The latter is found using the Pythagorean theorem:

h² = y² +(w/2)² = (6 units)² +((10 units)/2)² = 61 units²

h = √61 units

So, the area of 4 triangles is ...

area of triangular faces = 4(1/2)wh = 2(10 units)(√61 units) ≈ 156.2 units²

Now we have the areas of the parts, so we can add them together to get the total surface area:

surface area = base area + lateral area + area of triangular faces

= 100 units² + 200 units² + 156.2 units²

surface area = 456.2 units²

Please help I’d appreciate it I don’t understand thank you

Alexus [3.1K]

Your answer is the 3rd option.

$c = \pi \times d$
You must divide by π on both sides, therefore d=c/π
