exis [7]

9x + 3 = 7x +19

2x + 3 = 19

2x = 16

x = 8

So, x (8) is the number of chairs in each row with these setups.

Plug 8 into one of the equations and you will find how many chairs total there are.

9(8) + 3 = 75

There are 75 chairs total

Alisiya [41]

Answer:

5cm

Step-by-step explanation:

Given parameters:

Volume = 45cm³

Radius = 3cm

Unknown:

Height of the cone = ?

Solution:

Volume of cone is given as ;

V = $\frac{1}{3} \pi$ r² h

r is the radius

h is the height

45 = $\frac{1}{3} \pi$ x 3² x h

45 = 3π x h

h = $\frac{45}{3 x3.142}$ = 4.77cm

5cm is the closest answer choice
