Answer:
<h2>9</h2>
Step-by-step explanation:
(-)(-) = (+)
(-)(+) = (-)
(+)(-) = (-)
(+)(+) = (+)
-(-21) = (-)(-21) = (+)21 = 21
-12 - (-21) = -12 + 21 <em>use commutative property: a + b = b + a</em>
= 21 + (-12) = 21 - 12 = 9
$30
You can get this by setting up the equation below.
75 =
Then you would cross multiply to see what the base cost is. Then you could divide that number by the new number, 5000, to get the new cost.
Thhe answer is equal to A. x = 2.5.
Answer:
$3283.2
Step-by-step explanation:
Given data
Principal= $2700
Rate= 4%
Time= 5 years
Required
the final Amount A
The compound interest formula is
A=P(1+r)^t
Substitute
A=2700(1+0.04)^5
A=2700(1.04)^5
A=2700*1.216
A=$3283.2
Hence the balance in the account after 5 years is $3283.2
Answer:
Radius = 3.38 cm
Step-by-step explanation:
<em>Here</em><em>'s</em><em> </em><em>your</em><em> </em><em>sol</em><em>ution</em>
<em> </em><em> </em>=> The volume of cylinder = 720π cm^3
=> The height of cylinder = 20 cm
=> Radius = ?
=> Formula of volume of cylinder = πr^2h
=> 22/7 * r^2 * 20 = 720π cm^3
=> r^2 = (720*7)/20*22
=> r^2 = 11.45
=> r = √11.45
=> r = 3.38 cm
