Answer:
Step-by-step explanation:
$15,000×0.08 = $1,200 interest for 360 days
$1,200 × 30/360 = $100 interest
1) For number 1, you want to find the area of the square and the circle, then subtract: Area of square - area of circle. That will give you the area of the shaded region.
Area of square: 8² = 64, Area of circle: π4² = 50.27
64 - 50.27 = 13.73 ft²2)
For number 2, subtract the area of the rectangle by the area of the traingle.
Area of rectangle: (10)(6) = 60, Area of triangle:
= 21
60 - 21 = 39 in²3) For number 3, you could either find the entire rectangle and the empty space, and subtract the rectangle by the empty space, or cut the rectangle into sections and find each of the sections, then add them up. I'm going to find the entire rectangle then subtract it by the empty space. I think the problem is set up to be easier that way.
Area of rectangle: (12)(8) = 96, Area of empty space: (4)(4) = 16
96 - 16 = 80 in²
4) Find the area of the rectangle and the area of the semicircle. Subtract the rectangle by the semicircle.
Area of rectangle: (13)(6) = 78, Area of semicircle: π3² / 2 = 14.14
78 - 14.14 = 63.86 yd²
Answer:
1/4x + 3
Step-by-step explanation:
The question said one-third(1/3) not one-fourth(1/4).
1/3x + 4 can also be written as x/3 + 4.
Answer: 10.6
Step-by-step explanation: it has a .3% increase each time, therefore it would be D. 10.6
1. 3in =5ft, 6in=10ft, 9in=15ft, 12in=20ft, 18in=30ft, 21in=35ft (multiples of 3 for the top row, the bottom row is multiples of 5. when the second column appears 3x2 is 6 and 5x2 is 10, and keep going. whatever number you multiply 3 by is the same number you multiply 5 by.)
a) 30ft
b) Actual is 2.5ft and would be the bottom row. You would divide 5 by 2. Do the same for 3 and it is 1.5in.
2. Scale 2in = 4ft.
The scale dimensions of a room is 14x7
2×x=14 x=7 7×2in=14in. The actual wall would be 7×4=28ft
The scale drawing is 7in. 3.5×2=7in Then 3.5×4=14ft
Final dimensions, 28ft x 14 ft.
3. 2cm = 5m Scale
10cm = 25m. 10cm=2×5. 5m×5=25m
6cm = 15m, 6cm=2×3. 5m×3=15m
