Write and solve an equation to find the width of the box if its volume is 80 cubic centimeters. Then find its surface area.
Lelu [443]

Answer:

L=4.30cm

SA=  110.94cm^2

Step-by-step explanation:

Given data

Volume of box= 80 cm^3

We know that the volume of a box is given as

V= l^3

80=l^3

l= ∛80

l= 4.30cm

also the surface area of a box is given as

SA=2lw+2lh+2hw

SA= 2* 4.30* 4.30+2* 4.30* 4.30+ 2* 4.30* 4.30

SA= 36.98+36.98+36.98

SA= 110.94cm^2

Find out how long it takes a $3,500 investment to double if it is invested at 7%
Gala2k [10]

Answer:

9.99 years

Step-by-step explanation:

P=$3,500

r=7%=0.07

n=4(quarterly)

A= double of $3,500=

$3,500×2=$7,000

t=?

A=p(1+r/n)^nt

$7,000=$3,500(1+0.07/4)^4t

$7,000=$3,500(1+0.0175)^4t

$7,000=$3,500(1.0175)^4t

Divide both sides by $3,500

2=(1.0175)^4t

Take the log to base 10 of both sides

log2=4t × log1.0175

0.30103=4t × 0.00753

0.30103=4(0.00753)t

0.30103=0.03012t

t=0.30103/0.03012

t=9.99435

Approximately

9.99 years
