Charra [1.4K]

Answer:

90 people

Step-by-step explanation:

Total: $775

DJ: $250

Cake: $75

Unknown party guests each getting $5

Let the unknown be x

We can form an equation; DJ + Cake + x number of party guests = $775

250 + 75 + 5x = 775

325 + 5x = 775

Subtract 325 from both sides of the equals sign.

5x = 450

Make x the subject and divide both sides by 5

x = 90

There were 90 party guests.

Answer:

4:25

Step-by-step explanation:

Given that,

r₁ = 15 inches, r₂ = 6 inches

The area of the cylinder is given by :

$A=2\pi rh+2\pi r^2$

The ratio of surface areas of two cylinders,

$\dfrac{S_2}{S_1}=\dfrac{2\pi r_2h_2+2\pi r_2^2}{2\pi r_1h_1+2\pi r_1^2}\\\\\dfrac{S_2}{S_1}=(\dfrac{r_2}{r_1})^2\\\\=\dfrac{6}{15}^2\\\\=\dfrac{4}{25}$

Hence, the required ratio is 4:25.
