thanks. .dssss
First, converting R percent to r a decimal
r = R/100 = 5.3%/100 = 0.053 per year.
Putting time into years for simplicity,
53 days / 360 days/year = 0.147222 years.
Solving our equation:
A = 502.45(1 + (0.053 × 0.147222)) = 506.3704997767
A = $506.37
The total amount accrued, principal plus interest, from simple interest on a principal of $502.45 at a rate of 5.3% per year for 0.147222 years (53 days) is $506.37.
Integers
An integer is a whole number that is not a fraction
Whereas real numbers include fractions and so do rational numbers.
Rational numbers include terminating decimals and fractions. Meaning, they have an end number.
Pi for instance is an irrational number because it never ends
Answer:
The ratio of the surface areas and volume is 8((5y+5x) /25xy)
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes.
Let us assume that the radius =x
Radius r=5x/4
And the height =y
Height h= 5y/4
We know that the total surface area of a cylinder is
A total = 2πrh+2πr²
We can factor out 2πr
A total = 2πr(h+r)
The volume of a cylinder is given as
v= πr²h
The surface area and volume ratios
Can be expressed as
2πr(h+r)/πr²h= 2(h+r)/rh
= (2h+2r)/rh= 2h/rh + 2r/rh
= 2/r + 2/h
= 2(1/r + 1/h)
Substituting our value of x and y
For radius and height we have
= 2(1/5x/4 + 1/5y/4)
=2(4/5x + 4/5y)
=2*4(1/5x + 1/5y)
= 8 (5y+5x/25xy)
As we know that the sum of two sides of a triangle is greater than the third side ...
Option A is correct because 4+5=9>8
Option B is correct because 9+12=21>15
Option C is correct because 12+5=17>13
Hope it helps.....
