The total profit she earned over 5 years was $23,255. First, you have to find 20% of 3125, which can be found by multiplying 0.2 by 3125. Then, you add the product, 625, to 3125. The sum, 3750, is the profit she earned in year 2. You repeat these same steps until you reach year five (find 20% of 3750, add, repeat with new sum). Once you have each amount of each year, you add all of them together, giving you the total, $23,255.
Year 1- 3125
Year 2-3750
Year 3-4,500
Year 4-5400
Year 5-6480
Answer:
he bought 60 stamps
Step-by-step explanation:
6*5=30
30*2=60
3/4 miles
work:
1/3 x 4 = 4/12
4/12 + 5/12 = 9/12(answer)
9/12 ÷ 3 = 3/4(simplified)
Answer:
inches
Step-by-step explanation:
Let x inches be the length of one side of the frame. The frame is the square, so all sides have the same lengths.
Use formula connecting the area of the square and the side length of the square.
Since the area ofthe square is 55 square inches, we have
Answer:
110°
Step-by-step explanation:
This quadrilateral have the same size in AD and CD, and BA and CA, so it means that, if you cut this figure in the middle (from B to D), the two triangles will be identical, and the sum of the internal angles of a triangle is 180°, so:
(110°÷2) + (30°÷2) + <C = 180°
55° + 15° + <C = 180°
70° +<C = 180°
<C = 180° - 70°
<C = 110°
And you can test it making the sum of the internal angles of the quadrilateral. The sum of the internal angles of a quadrilateral is 360°, and the angles A and C have the same measure because AD=CD and AB=BC, so:
<A + <B + <C + <D
110° + 110° + 110° + 30° = 360°
