Answer: 96 green pens sold
Step-by-step explanation:
Black = 3 pens
Red = 5 pens
Green = 6 pens
--
Black = 7 packs
Red = 2 packs
Green = 4 packs
--
Black = 3 x 7 = 21 total pens
Red = 5 x 2 = 10 total pens
Green = 6 x 4 = 24 total pens
Total units for total pens = 21 + 10 + 24 = 55u
55u = 220
1u = 220/55
= 4
24u = 4 x 24
= 96 green pens sold
--
96 green pens were sold.
Answer:
A = $13,660.81
Step-by-step explanation:
P (principal) = $4,800.00
I (interest) = $8,860.81
First, convert R as a percent to r as a decimal
r = R/100
r = 6.2/100
r = 0.062 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 4,800.00(1 + 0.062/4)(4)(17)
A = 4,800.00(1 + 0.0155)(68)
A = $13,660.81
Answer:
Step-by-step explanation:
Hello,
We need to use the <u>distributive property</u> which means that for a, b and c real numbers a(b+c)=ab+ac
So here we can write
do not hesitate if you have any question
A) The greatest rectangular area will be the area of a square 10 m on each side, 100 m^2.
b) The new dimensions will be 11 m × 11 m.
.. The new area will be (11 m)^2 = 121 m^2.
c) The area was increased by 121 m^2 -100 m^2 = 21 m^2, or 21%.
d) Yes, and no.
.. If you increase the dimensions by 10%, the area will increase by 21%.
.. (40 m)^2 = 1600 m^2
.. (44 m)^2 = 1936 m^2 = 1.21*(1600 m^2), an increase of 21% over the original.
.. If you increase the dimensions by 1 unit, the area will increase by (2x+1) square units, where x is the side of the original. For x≠10, this is not 21 square units.
.. (41 m)^2 = 1681 m^2 = 1600 m^2 +(2*40 +1) m^2 = 1600 m^2 +81 m^2
