Janet invested $10,000, part at 2% and part at 12%. if the total interest at the end of the year is $600, how much did she invested at 2%
Answers
Janet invested $6000 at 2 %.
Let x = amount invested at 2 %. Then 10 000 - x = amount invested at 12 %
interest at 2 % + interest at 12 % = 600
0.02x + 0.12(10 000 – x) = 600
0.02x + 1200 – 0.12x = 600
0.10x = 600
x = 600/0.10 = 6000

The amount of money that Emerson makes if she sells all of the treat bags will be $119.
What is Algebra?
Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Emerson made 408 hand-crafted canine treats to sell at a nearby pet store. She places 24 treats in each pack and sells the sacks for $7 each.
The number of the treats will be given as,
⇒ 408 / 24
⇒ 17
Then the amount of money that she earns will be given as,
⇒ $7 x 17
⇒ $119
The amount of money that Emerson makes if she sells all of the treat bags will be $119.

Beth should buy 3 bags of fertilizer
Step-by-step explanation:

a. The figure consists of 9 isosceles triangles of side lengths 11 and vertex angle = 360/9 = 40°
Hence base angles = (180 - 40)/2 = 70°
Therefore, the base of the triangles = sin(40) × 11/sin(70) = 7.52
Hence area of figure = 9 × 0.5 × 7.52 × √(11² - (7.52/2)²) =349.99 ≈ 350 unit²
b. Area of a decagon
We note that the vertex angle = 36°
∴ Half the base = tan(18) × 5 = 1.62
Area = 10 × 1.62 × 5 = 81.23 unit²
c. The area of a hexagon =
s = 4 therefore, the area =

Area, A of a regular pentagon =
a = 15 ft., therefore, A = = 387.11 ft.²
Therefore, since a bag of fertilizer can fertilize 150 ft.², the number of bags of fertilizer that will fertilize 387.11 ft.² will be 387.11/150 = 2.58 bags
Therefore, since 2 bags of fertilizers will not be enough, Beth should buy 3 bags of fertilizer.
