Answer:

$SA=62.1\ m^2$

Step-by-step explanation:

step 1

Find the surface area of the smaller rectangular prism

$SA=2B+Ph$

where

B is the area of the base

P is the perimeter of the base

h is the height of the prism

$SA=2[(2.5)(1.5)]+2(2.5+1.5)(1.5)$

$SA=7.5+12=19.5\ m^2$

step 2

Find the surface area of the cube

$SA=6s^2$

where

s is the length side of the cube

$SA=6(2.5^2)=37.5\ m^2$

step 3

Find the lateral area of the cylinder

$LA=\pi DL$

where

D is the diameter of the base

L is the length of cylinder

$LA=(3.14)(0.5)(3.5)=5.495\ m^2$

step 4

Find the area of the base of cylinder

$A=\pi r^{2}$

we have

$r=0.5/2=0.25\ m$ ----> the radius is half the diameter

$A=(3.14)(0.25)^{2}=0.19625\ m^2$

step 5

Find the surface are of the composite figure

we know that

The surface area of the composite figure is equal to the surface area of the smaller rectangular prism plus the lateral area of the cylinder, plus the surface area of the cube, minus the area of the two bases of cylinder

$SA=19.5+5.495+37.5-2(0.19625)=62.1\ m^2$

A woman making $1500 per month has her salary reduced by 10% because of sluggish sales. One year later, after a dramatic improve

UkoKoshka [18]

Answer:

after the raise, her salary is $1755 per month
this is a +17% change from her original salary

Step-by-step explanation:

The multiplier of her original salary to her reduced salary is ...

(1 - 10%) = 0.90

The multiplier of her reduced salary after her raise is ...

(1 +30%) = 1.30

The multiplier of her raised salary from her original salary is ...

(0.90)(1.30) = 1.17 = (1 +17%)

Her salary after the 17% raise is ...

1.17·1500/mo = $1755/mo
