Answer:
$65 + $(-25) = $40
$65 - $25 = $40
Step-by-step explanation:
Profit made last week = $65
Profit made this week = - $25
Addition expression for her profit over the two weeks
Last week profit + this week's profit:
$65 + $(-25) = $40
Subtraction expression for her profit over the two weeks :
$65 - $25 = $40
Volume=heiht times area of base
base=circle
area of circle=pir^2
volume=hpir^2
diameter=2r
diametr/2=r
diameter=8.5
find radius
r=8.5/2
r=4.25
h=11.5
subsitute
v=11.5 times pi times 4.25^2
v=11.5 times pi times 18.0625
v=pi times 207.71875
round to hundreth
v=207.72pi in^3
volue=207.72pi in^3
if you want to aprox pi to 3.14 and solve for that then
v=207.72 times 3.14
v=652.24
so
v=207.72pi in^3 or
v=652.24 in^3 aprox (both aer eequatal)
Answer:
$4.68
Step-by-step explanation:
4.75+0.57=5.32
10-5.32=4.68
