The total number of customers who took the survey was 320. You can write it out like this :
45 144
—- = ——
100 ?
Then you can cross multiply (144 x 100 = 14,400) then divide that answer by 45 (14,400 \ 45 ) The answer you get it 320!!

a concrete pillar has the shape of a cylinder. it has a diameter of 6 meters and a height of 7 meters. concrete cost $116 per cu

GrogVix [38]

Answer:

The cost of the pillar is $22,947.12

Step-by-step explanation:

Diameter of the pillar = 6m

Radius = diameter / 2 = 6 / 2 = 3m

Height if the pillar = 7m

Volume of the pillar = πr²h

π = 3.14

V = 3.14 × 3² × 7

V = 3.14 × 9 × 7

V = 197.82m³

Volume of the pillar is 197.82m³

If 1m³ = $116

197.82m³ will cost $x

X = (197.82 × 116) / 1

X = $22,947.12

The cost of the pillar is $22,947.12

If 60% of a numbet is 18,what is 89% of the number

aliya0001 [1]

What is this number?

if 60%x=18

then

$\frac{60}{100}$ x=18

$\frac{6}{10}$ x=18
$\frac{3}{5}$ x=18
3x=18*5
x=6*5
x=30

and 89% of it:
$\frac{89}{100}$ *30= $\frac{89}{10}$ *3=26.7 which is the answer
