simple interest:
principal x ( 1 + (rate as decimal x number of years))
example if you put 100 dollars in a bank for 5 years at 5% interest at the end of the 5 years you would have:
100 x (1+(0.05 x 5)) = 100 x (1+(0.25)) = 100 x 1.25 = 125 dollars
125-100 = 25 dollars interest
Answer:
Formula for the SA (Surface Area) is 2πrh+2πr^2.
Replace the values and you get answer of 251.999570694 = 252pi
Answer:
62 cm
Step-by-step explanation:
Given the expressions for width (3x + 1) and length (5x - 2) as well as the formula for the perimeter of a rectangle: 2(5x - 2) + 2(3x +10), we can first solve for the simplified expression of 'x' and then substitute the given value of x = 4cm to find the total distance:
Distribute: 2(5x - 2) + 2(3x +1) = 10x - 4 + 6x + 2
Combine like terms: 16x - 2
Plug in '4' for 'x': 16(4) - 2 = 64 -2 = 62 cm
Answer:
5 cm
Step-by-step explanation:
32 / 4 = 8
40 / 8 = x
40 / 8 = 5
32 and 4 are corresponding, and 40 and x are as well. Find the relation between 32 and 4, then apply it to 40 to find the value of x.
Let x and y be your two consecutive whole numbers
x < sqrt(142) < y
x^2 < 142 < y
So, we are looking for x and y such that x^2 < 142 and y^2 > 142.
The closest squared number to 142 is 144 = 12^2.
Next is 11^2 = 121.
11 and 12 are consecutive.
11^2 = 121 < 142 < 144 = 12^2
Thus, 11 and 12 are your numbers
