Jessie deposited $920 into a savings account that pays a simple annual interest rate of 1.79%. how much interest will he earn after 5 years?

$82.34 interest will he earn after 5 years

Step-by-step explanation:

Use the formula:

             ......[1]

where,

I is the interest

P is the principal

R is the rate in decimal

T is the time in years.

As per the statement:

Jessie deposited $920 into a savings account that pays a simple annual interest rate of 1.79%.

⇒P = $920 , R= 1.79% = 0.0179

We have to find interest will he earn after 5 years.

T = 5 years

Substitute the given values in [1] we have;

Simplify:

I = $ 82.34

Therefore, $82.34 interest will he earn after 5 years

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )

answer: ratio of volume of cone (with 3 times the height and equal diameter) to volume of cylinder is 2 to 1. the value of π is not used.

step-by-step explanation:

radius is diameter/2 = 4.

area of circle is π r^2.

volume of cylinder is height × area of base = hπr^2 = 3(4^2) π = 48π cubic inches.

not knowing the formula for volume of cone, i calculate it using calculus (which is for calculating things).

volume of cone is integral 0 to h area(y) dy. area(y) is π r(y)^2. r(y) runs r to zero as y runs zero to h, r(0) = r, r(h) = 0.

r(y) = r - r/h y

area(y) = π (r - r/h y)^2 = π (r^2 - 2r^2y/h + r^2y^2/h^2) = π r^2(1-2y/h+y^2/h^2)

antiderivative area(y) = π r^2 (y-y^2/h+y^3/(3h^2))

integral 0 to h = π r^2(h-h^2/h+h^3/(3h^2) - (0)) = π r^2(h - h + h/3) = π r^2(h/3) = π/3 r^2 h

volume of this cone is π/3(4^2)18 cubic inches.

= 6 16 π = 96π cubic inches.

cone has twice the volume, 96/48.

cone height is 6 times the cylinder.

ratio of volume formula: π r^2 cancels.

cone over cylinder ratio is 6h/3 to h, 2 to 1.
