#1) so if the ratio is 2/3 and the other fraction is 16/?, all you have to do is figure out what it took to get there. For example, if the beginning fraction is 2/3 and the second one is 16/?, we at least know that 2 times 8 is 16, so all we have to do is multiply 3 times 8 to get the bottom number which is 24. So 24 is the amount of tan tiles they will need.

2. You are creating a cone-shaped hat for a kid’s costume. You measure the circumference of the child’s head and find it to be 2
Monica [59]
Just draw a triangle(front view) and the slant/inclined sides of it are known to be 8 and you found out radius as 3.26. so mark the diameter by doubling radius.

so the material required would be a slice(like pizza slice) of a circle of radius= 8 and arc length = circumference given ,that is 20.5

now using this find the area of sector/slice. its the answer to the last bit.

now coming to next question, go to the kitchen and take any can and measure its dia and height by using a scale. and you might already know the formula to find the suface area of cylinder.

Write the formula for a function d(x) that describes the distance between the point P and a point (x,y) on the line. You final a
vlabodo [156]

Answer:

d(x) = √[(x - 2)² + (3x - 1)²]

Step-by-step explanation:

The distance between two points with coordinates (x₁, y₁) and (x₂, y₂) is given as

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

So, the distance between point (2,0) and a point (x,y)

d = √[(x - 2)² + (y - 0)²]

d = √[(x - 2)² + (y)²]

But the point (x,y) is on the line y = 3x - 1

We can substitute for y in the distance between points equation.

d(x) = √[(x - 2)² + (3x - 1)²]

The answer is 6 people.
