Yolanda deposits $300 per month in an account with an APR of 6%, while Zach deposits $3600 at the end
bonufazy [111]

Answer:

Yolanda will have a balance of $34,043.10 in 14 years.

Step-by-step explanation:

This is an Ordinary annuity question where you pick the hint from the equal and recurring monthly payment.

To find the Future value of Yolanda's savings after 14 years, use Future value of annuity formula FVA = \frac{PMT}{r}[1-(1+r)^{-t} ]\\

PMT= recurring payment = $300

r = discount rate; monthly rate in this case = 6% / 12 =0.5% or 0.005 as a decimal.

t = total duration ; 14 *12 = 168 months

Next, plug in the numbers into the FVA formula;

FVA = \frac{300}{0.005} [ 1-(1+0.005)^{-168} ]

FVA = 60,000 * 0.5673849

FVA = 34,043.0969

Therefore, Yolanda will have a balance of $34,043.10 in 14 years

What is the surface area of the cone to the nearest whole number? Use 3.14 for π.
IRISSAK [1]
Hello!

We know that surface area of a cone = pi(r^2) + pi(rL) where L is the Slant height and R is the Radius and h is Height.
So, 30 is height, and half of 32 is the radius, then we just plug and chug,

An in Short, Your Answer would be 2512, Option "A"

Hope this Helps! :)

Mr. Baldwin is packing the shipping box with ring boxes that are cubes with an edge length of 3/2 inches. If he completely fills
Alinara [238K]

Answer:

10 ring boxes

Step-by-step explanation:

First, we need to calculate the total surface area of each cube ring boxes

The surface area of each square boxes = 6L²

Given that L =1.5inches

Total surface area = 6(1.5)²

Total surface area = 6(2.25)

Total surface area = 13.5in²

<em>Since the question is incomplete. Let us assume the total surface area of the shipping box is 135in²</em>

<em></em>

Number of ring boxes he can ship = 135/13.5

Number of ring boxes he can ship = 10

Hence the number of ring boxes he can ship is 10 ring boxes

<em />

<u><em>NB: The total surface area of the shipping box was assumed</em></u>

<u><em></em></u>
