Answer:

y = 3x

Step-by-step explanation:

Note the values of y are 3 times the corresponding values of x, that is

x = 4 → y = 4 × 3 = 12

x = 7 → y = 7 × 3 = 21

x = 10 → y = 10 × 3 = 30

x = 13 → y = 13 × 3 = 39

Thus the equation describing the proportion is

y = 3x

Tricky but not crazy hard. You could use th x/y method where you turn it into a cross multiplication fiasco.

or you can try your guesses through what ever equals 1/2 when you add one to the denominator. the answer you are looking for is 2/3

2/3 + 1 for the numerator = 1.

2/3 + 1 for the denominator = 1/2.

The total surface area of a cone whose radius is 2 r and slant height 2l is

vampirchik [111]

Answer:

$A=4\pi r(l+r)$

Step-by-step explanation:

The total surface area of a cone is given by :

$A=\pi rl+\pi r^2\\\\=\pi r(l+r)$

Put r = 2r and l = 2l in the above formula

$A=\pi \times 2r(2l+2r)\\\\A=2\pi r(2l+2r)\\\\=2\pi r \times 2(l+r)\\\\=4\pi r(l+r)$

Hence, the total surface area of the cone is $4\pi r(l+r)$ .

A room is 12cm long, 7cm wide and<br>4cm high find the area <br>the ceiling

aksik [14]

Hey there!
I think that it safe to say that this room is a rectangular prism. Therefore, the top and bottom (floor and ceiling) have the same area. We see that our floor dimensions are 12 cm long and 7 cm wide. This also applies to the ceiling. Let’s take our two sides and multiply then to find our area.

12(7)=84

Therefore, the area is 84 square centimeters.

I hope that this helps!
