57% people ordered steak. 120 did not. how many customers were there that night?

1 answer:

4 0

X - number of customers

$120+57\%x=x\\
120+0.57x=x\\
0.43x=120\\
x\approx297.07$

There can't be a fraction of the number of people, so there must be some mistake in the question.

Find the area of each figure. Round to the nearest tenth if necessary.

natita [175]

Answer:

Solution given:

diameter(d)=6mm

base(b)=8mm

height (h)=5mm

Area of figure=area of parallelogram +area of semi circle

base*height+½π(d/2)²
8*5+½*π×(6/2)²
40+14.14
54.4mm²
Area :54.14mm²

for triangle

base[b]=6ft

height(h)=9ft

for square

length[l]=9ft

Area of figure=area of square +area of triangle

=l²+½*b*h
=9²+½*6*9
=81+27
=108ft²
Area: 108ft²
