9. A rectangle has an area of 45m²

love history [14]

Answer:

$Lenght=3\,m$

Product of length and width= $45$

Step-by-step explanation:

The product of the length and width of the rectangle is called the area of the rectangle.

Area of the rectangle= $45\,m^2$

$Width=15\,m$

Area of the rectangle= $Length\times Width$

$45=Length\times 15\\\\Length=\dfrac{45}{15}\\\\ Length=3\,m$

The product of the Length and Width of the rectangle is :

$=3\times15\\\\=45 m^2$ i.e area of the rectangle.

2/7m-1/7=3/14<br><br> Please solve showing work

lawyer [7]

(2/7)m - (1/7) = 3/14
2m/7 =(3/14) + (1/7)
2m/7 = (3/14) + 2(1/7)
here we are multiplying 2 with 1/7 to make the denominator same for addition.
2m/7 = (3/14) +(2/14)
2m/7 = (3 + 2)/14
2m/7 = 5/14
2m = (5 *7)/14
2m = 35/14
2m = 5/2
m = 5/4
m = 1.25
So the value of "m" is 1.25

What is the balance after 15 years in a savings account that earns 2% interest compounded bimonthly when the initial deposit is

Ierofanga [76]

Answer:

$1348.07

Step-by-step explanation:

Hello!

<h3>Compound Interest Formula: $A = P(1 + \frac rn)^{nt}$ </h3>

A = Account Balance
P = Principle/Initial Amount
r = Rate of Interest (decimal)
n = Number of times compounded (per year)
t = Number of Years

<h3>Given Information</h3>

Account Balance = ?
Principle Amount = $1000
Rate of Interest = 0.02

Why is the Rate 0.02?

This is because we are gaining money, so the multiplier should be greater than 1. We already added 1, which is 100% so you simply add the 0.02 for the extra 2%.
